A Global Event: the Coronavirus Pandemic of 2020

Just as COVID-19 was beginning its worldwide tour in February, NASA released a remastered version of the 'Pale Blue Dot' image of the Earth taken 30 years ago from the outer reaches of the solar system by Voyager 1. That image shows how small the Earth really is, and now the coronavirus is delivering that same message in a more visceral fashion.

As a pandemic that is affecting people in every part of our planet, COVID-19 is but the latest global phenomenon that is shaping and changing life all over the Earth. 

We are familiar with the economic changes that we know as globalization. Historians argue that the internationalization of business we see today goes back to the world-girdling empires of the 19th century, often business driven, that relied on advances in transportation such as steamships, railroads, and more recently automotive vehicles and aircraft. One hundred years ago, the large movements of people related to World War I facilitated the great influenza pandemic of 1918 to 1920. 

Since that time, we have seen revolutionary changes in communications such as radio, television, the internet and social media that have tied our world closer together, not always with happy results. 

Fifty years ago this spring, the first Earth Day took place at a time when transnational environmental organizations were first being created and when astronauts came home from the Moon with iconic photos of the whole Earth in the darkness of space. 

The declaration of the COVID-19 pandemic on March 11 and the big changes that are now affecting billions of people constitute a major historical event that will ensure that 2020 is long remembered. Even under the best case scenarios, the world and the lives of most everyone in it will be changed. It remains to be seen what changes will endure.

Beyond the casualties of disease and economic dislocation caused by COVID-19, I am wondering what lessons will be drawn from this universally shared experience. To start off, there are encouraging signs that many people are realizing the value of public health. The majority of people who haven’t understood that our public health departments have saved many more lives than the much more expensive and higher profile acute care system are receiving a powerful lesson from the coronavirus. 

In a time that will never be remembered for the quality of leadership from our political classes or economic elites, public health professionals, many of them women, are stepping in to fill the void. We are learning about the importance of even the lowliest health care workers, the cleaners and janitors, who fight germs despite decades of unfriendly attention from budget cutters and efficiency experts.

Like other plagues and pandemics before it, the coronavirus is exploiting weaknesses in our economic and social structures. It will be interesting to see what lessons are learned in societies that have come to tolerate inequality, poverty, and a lack of social solidarity. To fight COVID-19, we face the paradoxical requests to show social solidarity by social distancing, and to slow the virus by closing borders and doors when COVID-19 has already overcome the walls and the nationalist and populist politics that were supposed to protect many countries from problems originating in other parts of the world.

When the pandemic comes to an end, the population of Earth will have to return to facing the challenges of an even bigger threat to our shared future, climate change. With luck the lessons humanity learns fighting a virus will make a proper impression on those people who have up to now chosen to deny or deprecate the scientific evidence of climate change.

On that pale blue dot where we all live, we will have to learn to think in planetary terms in more than matters of economic gain if humanity hopes to endure.

John S. MacDonald, Entrepreneur, 1936-2019

Engineer and entrepreneur John S. MacDonald stamped his name on the Canadian space business by building a technology, space and information services company literally from the ground up. 
MacDonald Dettwiler and Associates Ltd. or MDA, which Mr. MacDonald founded in 1969 in the basement of his Vancouver home with fellow engineer Werner (Vern) Dettwiler, began producing computer systems, but turned to space when an opportunity arose to build a ground Station in Canada for the Landsat-1 remote sensing satellite following its launch in 1972. 
By 1998, when Mr. MacDonald retired as chair of MDA, the company had overtaken Spar Aerospace as Canada’s largest space contractor and acquired Spar’s space business, including the work of building the Canadarm for the U.S. space shuttle and the International Space Station. 
Just four days after Mr. MacDonald died in Vancouver on December 26 due to cerebral amyloid angiopathy, MDA was back in the news with the announcement that it will return to Canadian ownership in 2020 after two years under the wing of Maxar Technologies Inc.
John Spencer MacDonald was born in Prince Rupert, B.C. on August 13, 1936. He demonstrated his interest in electronics early when he repaired radios in fish boats there while in high school. Mr. MacDonald renewed his links with the area later in life when he served as Chancellor of the University of Northern B.C. from 2010 to 2016.  
After earning an undergraduate degree in applied science at the University of B.C. in 1959, Mr. MacDonald earned a master’s degree in 1961 and a Ph.D. in 1964, both from the Massachusetts Institute of Technology. After teaching at MIT, he returned to Vancouver where be began teaching electrical engineering at UBC.
Mr. MacDonald married his wife Alfredette in 1959 after having met her while on a summer job with Atomic Energy of Canada in Chalk River, Ont. They soon had two sons, Neil and Jay.
Although Mr. MacDonald enjoyed teaching, he noticed that many of the young engineers he was training at UBC were leaving the province to find work, and as he explained to science writer Barry Shanko in an interview, “I wanted to do something meaningful in an engineering sense.”
The result was that he and Mr. Dettwiler founded MDA, which started by building monitoring and control systems for microwave networks and pipelines. Mr. MacDonald was president of the firm until 1982.
MDA principal scientist David Sloan alerted Mr. MacDonald to the fact that the Canadian government wanted to build a ground station to receive images and other data from Landsat. As a result, MDA built a major part of the Canadian ground station, and armed with new designs for portable digital ground stations, MDA went on to capture a major part of the world market for portable civilian ground stations for remote sensing satellites.
Working with the Canadian Centre for Remote Sensing and its director general, Lawrence W. (Larry) Morley, Mr. MacDonald and MDA turned to remote sensing using synthetic aperture radar, where radar signals are used to create high definition images. Satellites and aircraft using this type of radar can obtain images at any time of day or night, and are not impeded by cloudy weather. The images are useful for mapping, environmental monitoring, and following masses of ice. 
MDA developed a digital processor for synthetic aperture radar that flew on Seasat, an American ocean research satellite that was launched in 1978. When the Canadian government launched Radarsat-1 in 1995, Spar Aerospace was the main contractor. MDA was a major subcontractor on Radarsat-1, and it created and sold a whole variety of data products from the satellite for many different users.
Around that time, MDA drew up a concept for Radarsat-2 which had much greater capabilities than the first Radarsat. Spar Aerospace resisted Mr. MacDonald’s pleas to incorporate MDA’s ideas into its Radarsat-2 proposal because it considered them too risky. So MDA bid on the job with its own concepts and in 1998 won the competition to build Radarsat-2. Spar soon left the space business and sold its space divisions to MDA.
“My basic thesis was that if we’re going to compete in the first half of the 21stcentury, we have to have a much more information-rich spacecraft than Radarsat-1,” Mr. MacDonald recalled.
The second Radarsat was so powerful that the U.S. government declined to launch it as it had done for previous Canadian satellites because of security concerns, and so Radarsat-2 was launched by a Russian rocket in 2007 and became another success.
MDA has since built the twin-satellite Radarsat Constellation Mission, which was launched last June atop a Falcon rocket, and has continued work on the Canadarm robot arm on the U.S. space shuttle, Canadarm-2 on the International Space Station, and a new Canadarm planned for the U.S. Lunar Gateway space station. MDA also became known for the information products it has developed from remote sensing data, including images and maps  tracing the movement of ground surfaces and sea surfaces, and images of icebergs, oil spills, and areas affected by natural disasters.
When asked about his major legacy, Mr. MacDonald said: “It’s the people that rank with the best of the world in advanced technology in B.C. and Canada.”
While he tried to hire the best people for his technical teams, Mr. MacDonald did not rely on credentials. He once took on an engineer who expressed surprise at his hiring because he hadn’t yet completed his degree but saw numerous employee diplomas decorating the office wall. “We don’t need any more wallpaper here,” Mr. MacDonald replied.
After 1998, Mr. MacDonald served as chair and CEO of solar energy company Day4 Energy Inc. from 2001 to 2014. 
Mr. MacDonald was an avid amateur astronomer and enjoyed sailing the B.C. coast. He and his wife enjoyed travelling to every part of the world. 
Mr. MacDonald has earned many honours and awards, including the Order of Canada in 1988. He is survived by his wife, two sons, and three grandchildren.

Bruce Aikenhead, Canadian Space Pioneer, 1923-2019

August 21, 2019

In 1959, the National Aeronautics and Space Administration (NASA) introduced America’s first astronauts to the world. Nearly 25 years later, Canada’s first astronauts were chosen. Both groups of astronauts were trained by Bruce Aikenhead, a soft-spoken Canadian who began a long career in spaceflight after losing his job when the CF-105 Avro Arrow jet interceptor was cancelled.
His career also included service in the Royal Canadian Air Force during the Second World War and work at well-known Canadian firms including Electrohome, CAE Inc., and Spar Aerospace, but Mr. Aikenhead, who died this month, will be best remembered as one of the key individuals in the early years of Canada’s space program.
Until the Canadian Space Agency opened for business in 1989, Canada’s space efforts were spread amongst a variety of government agencies and private contractors. No one could match Mr. Aikenhead’s variety of experience in Canada’s space sector or his three years in a key role at NASA.
Shortly after Bruce Alexander Aikenhead was born, on Sep. 22, 1923, in Didsbury, Alta., his family moved to London, Ont., where he was raised. During the war, Mr. Aikenhead joined the RCAF and serviced radar equipment while attached to the Royal Air Force in England and later in India.
Mr. Aikenhead studied radio physics at the University of Western Ontario after the war and completed an Honours Bachelor of Science degree in radio physics in 1950. He married the former Helen Wait in 1947, and together they raised their family. Starting in 1950, Mr. Aikenhead worked at Dominion Electrohome Industries in Kitchener on production engineering of radio receivers, car radios and televisions.
In 1955, Mr. Aikenhead turned to aviation, joining Canadian Aviation Electronics in Montreal, now known as CAE, where he helped develop aircraft simulators. Three years later, he moved to Avro Canada in Malton, Ont., where he worked on the flight simulator for the Avro Arrow, a highly advanced aircraft that was capable of flying twice the speed of sound.
Six months after Mr. Aikenhead started work at Avro, the Conservative government of John Diefenbaker cancelled the Arrow program on Feb. 20, 1959, throwing thousands of skilled people out of work. A few weeks after the cancellation, top officials from NASA flew to Malton and hired 25 former Avro engineers including Mr. Aikenhead to work on Project Mercury, which would launch the first U.S. astronauts into space.
On the day in April 1959 that Mr. Aikenhead reported to work at NASA’s Langley Research Center in Hampton, Va., he was assigned to join the team that would train the Mercury astronauts. He then went through his formal employment induction procedures for NASA alongside the seven astronauts, who had also started work that day. For the rest of his time at NASA, he and the astronauts worked in adjacent offices.
With his experience in simulators, Mr. Aikenhead developed a device that simulated the cabin of the Mercury spacecraft, and he helped train Alan B. Shepard Jr. and Virgil I. Grissom for their suborbital launches in 1961. Mr. Aikenhead and his colleagues were training John H. Glenn Jr. that fall for his first American orbital flight when NASA decided that its human space program would relocate to Houston, Texas.
Along with some of the other engineers from Canada, Mr. Aikenhead decided that Houston was too far away from home, and he was able to get another job at CAE working on aircraft simulators. When his friend Col. Glenn made his historic flight on Feb. 20, 1962, Mr. Aikenhead could only follow it on the radio from his new home in Montreal.
While Mr. Aikenhead's time at NASA evokes movies such as The Right Stuff, he and his family also had to live with the realities of segregation in the U.S. South as depicted in the 2016 film Hidden Figures. Once back in Montreal, Bruce and Helen Aikenhead made sure that their home was open to international students studying at McGill University.
In 1966, Mr. Aikenhead returned to the space sector when he decided to join Dr. Gerald Bull of McGill in the High Altitude Research Program, which sought to develop cannons capable of launching satellites into orbit. The program ended the following year when the Canadian government withdrew financial support, and Dr. Bull went on to notoriety by developing cannons for military clients around the world until his still-unsolved murder in 1990.
After his layoff, Mr. Aikenhead soon found a job at RCA Canada in Montreal, where he was project engineer for the ISIS 2 spacecraft, the fourth and last of Canada’s first generation of satellites that explored the ionosphere as part of the International Satellites for Ionospheric Studies program. Following the launch of ISIS 2 in 1971, he worked on the Communications Technology Satellite, which after its launch in 1976 was known as Hermes and pioneered direct-to-home and other communications technologies.
By then, RCA had been purchased by Spar Aerospace, which assigned Mr. Aikenhead to work with the National Research Council of Canada (NRC) on a program to build the Space Shuttle Remote Manipulator System for the U.S. Space Shuttle. In 1981, Mr. Aikenhead moved to the NRC in Ottawa as deputy program manager for what became known as the Canadarm.
The Canadarm proved itself in early shuttle flights, and in 1983, the Canadian government followed up on NASA’s invitation to fly Canadian astronauts by selecting five men and one woman for the Canadian Astronaut Program. Mr. Aikenhead was involved in the final selections, and with his experience at NASA, he quickly became involved in training the Canadian team. When Marc Garneau was selected to be the first Canadian to fly in space, Mr. Aikenhead’s contacts at NASA helped open many doors in Houston for the Canadians prior to Cmdr. Garneau’s flight in October 1984.
Mr. Aikenhead was put in charge of the Canadian Astronaut Program in 1986, but the program was effectively on hiatus for a time because of the loss of the shuttle Challenger that year. He presided over the program’s transfer from NRC to the CSA in 1989, the shuttle flights of Canadian astronauts Roberta Bondar and Steve MacLean in 1992, and the selection of Canada’s second group of astronauts, including Chris Hadfield and Julie Payette, now the Governor-General of Canada.
In March 1993, Mr. Aikenhead retired and moved to Salmon Arm, B.C. with his wife, Helen, who died in 2005. Mr. Aikenhead was named an officer of the Order of Canada in 1997. During his retirement, Mr. Aikenhead indulged his love of jazz and opera, and became a founder of the Okanagan Science Centre in Vernon, where he developed exhibits on space science and took part in school programs.
Mr. Aikenhead’s death of natural causes in Vernon, B.C. on Aug. 5, brought quick responses from Canadian astronauts. Mr. Garneau, now Canada’s Minister of Transport, praised him as a mentor, Robert Thirsk remembered him as the “go-to guy” when astronauts needed information about space travel, and Mr. Hadfield called him “kind, smart, hard working and humble.”
Mr. Aikenhead, who was 95, is survived by his son, Steve Aikenhead; and daughters, Kasey Bernz, Elizabeth Aikenhead, Barbara Newton and Jane Swaine (who was fostered by the Aikenheads).

Voyager 1 Upended Our View of Space - 40 Years Ago

Jupiter and its four Galilean moons - Io, Europa, Callisto and Ganymede - as seen by Voyager 1. NASA image.
Forty years ago this week we got our first real closeup view of Jupiter and its system of moons, a moment that I believe was a turning point in the history of space exploration.

Voyager 1 flew by Jupiter on March 5, 1979, opening an extraordinary decade of exploration by this spacecraft and and its twin Voyager 2 after their launches toward the outer solar system in 1977. Both spacecraft flew by Jupiter and Saturn, and Voyager 2 went on to visit Uranus in 1986 and Neptune in 1989. Today both spacecraft are still sending back data after having effectively flown outside of the solar system.

When Voyager 1 flew by Jupiter, it sent back eye popping images of Jupiter and its four major moons, Io, Callisto, Ganymede and Europa. For the first time, Jupiter’s complicated atmosphere could be seen with full clarity. The Voyager images transformed the four Galilean moons in the eyes of Earthbound observers from anonymous spheres into worlds of their own: Io was a reddish pockmarked moon that at first glance resembled a pizza, Ganymede was marked with craters and grooves, Europa appeared as an icy but relatively smooth world, and Callisto also was icy but covered with craters. Voyager made many more discoveries about the Jovian system, including a ring around Jupiter and new smaller moons orbiting the biggest planet in our solar system.

The day after the spacecraft’s flyby, Voyager Project Scientist Ed Stone said: “I think we have had almost a decade’s worth of discovery in this two-week period."

Three days after its closest approach to Jupiter, the departing Voyager 1 looked back and shot an image of a crescent Io, mainly to verify the accuracy of Voyager’s navigation system. When a member of Voyager’s navigation team, Linda Morabito, examined the image, she found what looked like a cloud rising from the moon's surface. As the smallest of Jupiter’s four Galilean moons, Io doesn’t have an atmosphere, so Voyager scientists soon reached the then surprising conclusion that Io has active volcanos, the first body other than the Earth known to have them.

In retrospect, I look at Voyager 1’s flyby of Jupiter the first real “wow” event of humanity’s reach into space. The most exciting thing about the space probes that came before Voyager was that humans had actually succeeded in exploring worlds beyond the Earth.

Their discoveries didn't really impress the public. Humanity’s reach for the Moon culminated with landings in places that resembled slag heaps instead of the mountainous spires that many people had expected, our first robotic visits to Mars dashed our hopes of finding life, Venus was shrouded by clouds, and Mercury was a cratered world that resembled our own Moon. Two Pioneer spacecraft had flown by Jupiter in 1973 and 1974, and their flights proved that spacecraft could survive the journey through the high radiation environment surrounding Jupiter. But their rudimentary imaging systems gave us only the smallest hints of the beauty of Jupiter and its moons. 

These “meh” moments were one reason space exploration seemed to fall out of public favour in the 1970s. 

I’m not saying that our early explorations were not important or that their discoveries did not excite scientists, but to the general public, the headlines were that humans had walked on the moon and robots had given us close-up views of other worlds, not what these explorers had actually found.

Finally, in March 1979, Voyager 1 provided images and other data that showed that our solar system contained many surprises. These results drew attention from the public, and more media were on hand when Voyager 2 flew through the Jovian system later in the year. Even bigger crowds and more media coverage were in evidence when the Voyagers provided stunning close-up views of the Saturnian system in 1980 and 1981. 

I joined the media hordes at the Jet Propulsion Laboratory for Voyager 1’s flight through the Saturnian system, and the only disappointment was the opaque cloud layer that shrouded the largest Saturnian moon, Titan. More attention was paid to the spectacular features Voyager found on other moons and the strange findings from Saturn’s rings, including shepherd moons.

Titan eventually gave up its secrets nearly a quarter century later when the Cassini spacecraft arrived for a long visit to Saturn with the Huygens lander that touched down on Titan's surface and found lakes of hydrocarbons and other astonishing features. Jupiter and its moons have also been explored by the Galileo spacecraft and is now being investigated by the Juno spacecraft, which is sending back amazing images of its own. 

Not long after the Voyager planetary flybys came to an end, NASA launched the Hubble Space Telescope in 1990. Although Hubble couldn't operate fully until 1994 due to the problems with its main mirror, it began to send back an amazing stream of images and other data that have helped upend our view of the universe. Hubble images, including those of the marks left on Jupiter by Comet Shoemaker-Levy 9, the ‘Pillars of Creation’ in the Eagle Nebula, the Hubble Deep Fields and many others, have captured the imaginations of many people. 

Hubble has found that the universe is a larger, more colourful and more amazing place than what we had previously thought. Other space telescopes such as Chandra and Spitzer have made discoveries of their own, and the Kepler and TESS space telescopes are finding a variety of unexpected planets orbiting distant stars. In recent years a string of rovers have revealed striking geography on Mars and found tantalizing hints of life on the Red Planet. The New Horizons spacecraft amazed many people on Earth with its surprising views of Pluto in 2014, and it started off 2019 with the first view of a Kuiper Belt object.

Today we see the universe as a very different place from what we imagined forty years ago, and new questions regularly arise about its nature. Today's discoveries are just the latest in a string that followed Voyager 1's astounding findings when it arrived at Jupiter four decades ago.

Looking Back at the RASC's 150th Anniversary

The Royal Canadian Mint's coin celebrating the RASC.

Now that 2019 is well under way, I am looking back on last year’s 150th anniversary celebrations held by the Royal Astronomical Society of Canada, whose membership includes more than 5,200 amateur and professional astronomers from every part of Canada. These celebrations were especially memorable for me because midway through the year I had the honour of becoming President of the RASC, succeeding my friend Colin Haig from Ontario. 

In 2018, the RASC obtained recognition in the form of special stamps issued in June by Canada Post, and a commemorative coin created by the Royal Canadian Mint that includes a piece of a meteorite. As a long-time stamp collector, I was thrilled to help unveil the stamps at the 2018 RASC General Assembly in Calgary. The anniversary coin sold out within hours of going on sale, and I was lucky to find one in a local post office for my own collection.

Much of the credit for this recognition goes to the RASC's Executive Director, Randy Attwood, who persuaded both the Mint and Canada Post to include our sesquicentennial in their 2018 commemorative programs.

The RASC had two national star parties in 2018, and the first one in January was carried live in a nationwide webcast. Members across Canada, including myself, have contributed astrophotos, sketches, and other artwork to our website, and prizes are now being given out. 

My colleagues on the RASC History Committee have been busy. Committee chair Randall Rosenfeld and Board Member Heather Laird have created a great set of podcasts on our shared history in RASC, which can all be found on the website. Much of our General Assembly in Calgary was taken up with an excellent set of papers in a seminar called A Shared Sky: The RASC 1868–2018. We are now working on revising those papers for publication in a book in the near future.

Like many other RASC members, I enjoyed the great hospitality and terrific speakers at the 2018 General Assembly from June 28 to July 1 at the University of Calgary. The opening ceremony involving local First Nations’ speakers and dancers at the U of C’s Rothney Astrophysical Observatory was especially memorable.

During 2018, I was able to visit a number of centres, including the Toronto Centre where the RASC was created in 1868. I also spoke about the Hubble Space Telescope at my home centre in Victoria and at the Vancouver, Winnipeg and Sunshine Coast Centres as well.

A special highlight for me was enjoying the magnificent beauty of Yukon when I spoke at the Northern Nights Dark Sky Festival at Kluane National Park in September, which I wrote about in this blog in October. I rarely get to see the Northern Lights at home on the West Coast, but this display took me back to the time many years ago when I first joined the RASC as an adolescent at the Edmonton Centre, and where I quickly became an enthusiastic auroral observer.

My home centre in Victoria took full part in the RASC sesquicentennial activities, and it also was involved in celebrations led by the National Research Council of Canada marking the 100th anniversary of first light at the 1.8 metre Plaskett telescope at the Dominion Astrophysical Observatory in Saanich. 

In 2019, I have already visited the Edmonton and the Prince George Centres, and I am looking forward to visits soon to the Calgary and Okanagan Centres. The 2019 RASC General Assembly will take place at York University in Toronto June 13 to 16. Members of RASC will be meeting jointly with members of the American Association of Variable Star Observers, and we will be celebrating the 50th anniversary of Apollo 11’s historic landing on the Moon with a talk by James Hansen, author ofFirst Man: The Life of Neil A. Armstrong, the book that inspired the recent movie.

As the RASC’s sesquicentennial goes into the history books, it is being followed up by plenty of RASC activity in 2019.

RASC members and visitors mark the 100th anniversary of public outreach activities at the Dominion Astrophysical Observatory.

Sadness and Celebrations for the Hubble Space Telescope

Nancy Grace Roman in 2017. NASA Goddard Photo.

On prominent display in my office is one part of the Lego Women of NASA set showing astronomer Nancy Grace Roman and the Hubble Space Telescope. On Christmas Day, Roman passed away at age 93. The loss of the woman widely acclaimed as the Mother of HST marks the end of a remarkable month of celebration and sadness for the Hubble Telescope team, now well into its 29th year of operating the great space telescope.

Roman studied astronomy despite being strongly discouraged from doing so, and university astronomy departments actively discriminated against women when Roman completed her graduate work in the 1950s. She took a job at NASA in 1959 a few months after the space agency began operations as its first Chief of Astronomy. During her career at NASA, Roman played an important role in fostering space-based astronomy through small scale space telescopes starting with the Orbiting Solar Observatory and building up to the formal start of work on HST not long before her retirement in 1979. 

Much of her work on HST involved getting astronomers, engineers and contractors to work together, an often difficult task. Her early research work in astronomy showed great promise, but she sacrificed that for the administrative work that helped much great science get off the ground, literally and figuratively. 

Although I didn’t have the opportunity to interview Roman while working on my history book on HST operations (which I hope will soon move to the publication process), I did meet her at a NASA history conference a decade ago. In her recent interviews, Roman expressed her pleasure that there are now many women astronomers in senior positions at NASA and elsewhere, but added there is still much room for improvement.

Many of those women have been or are involved with the Hubble Telescope, and earlier in December, the Space Telescope Science Institute (STScI), which has responsibility for Hubble's scientific operations, announced that their most recent process for awarding research time on HST had succeeded in eliminating gender bias. With support from NASA, STScI has worked for several years to eliminate gender bias from the telescope time allocation process, but the measures from previous years had always fallen short. For the telescope time awarded in 2018, consultants helped ensure that the identities of proposing scientists were not raised in any way during the allocation process. As a result, STScI succeeded in eliminating the gender bias from their process.

This news would doubtless have pleased Roman and also Riccardo Giacconi, the first director of STScI, who died earlier in December at age 87. STScI held a landmark conference on the place of women in astronomy in 1992 with Giacconi’s full support, a conference that helped open many doors to women astronomers at the Institute and around the United States and elsewhere.

Giacconi’s contributions to astronomy went far beyond HST -- he is credited for creating the field of X-ray astronomy and won the Nobel Prize for Physics for his work in that field. In the dozen years he led STScI, Giacconi often caused controversy but made sure that the voices of scientists were always heard in decisions about the space telescope. He hired a top-flight staff for the institute and saw it create an astronomical data archive that will long outlive the Hubble Telescope. By ensuring that all HST data are made available in calibrated form, he has opened it to large numbers of astronomers and other experts who might not otherwise be able to use it.

NASA and STScI also celebrated the 25th anniversary this month of the historic first shuttle servicing mission of HST. The seven astronauts on the STS-61 mission restored HST’s vision, which was afflicted by an incorrectly ground main mirror, by installing two new instruments and by making other needed repairs. Their work turned Hubble from a national embarrassment to a symbol of America’s technological power, and STS-61 was followed by four more servicing missions that upgraded HST and extended its life to the present day and beyond.

I was able to attend part of this celebration, catching up with many friends from STScI and NASA. There I saw the friendships that were forged by the teamwork between the shuttle astronauts, the people who trained them, and the satellite servicing experts from the NASA Goddard Space Flight Center who worked with others from STScI and other NASA contractors to design the ingenious repairs for HST. 

The last shuttle servicing mission flew to HST nearly a decade ago, and no more missions are possible because the shuttle was grounded in 2011. That means HST is slowly breaking down as parts wear out. In October, HST went into safe mode while experts at Goddard dealt with problems with the gyroscopes that measure HST’s motion and are a crucial part of its pointing system. The success of their work and Hubble’s return to service in November no doubt added to the mood of celebration at the party I attended.

Also in December, STScI and NASA issued their 1000th news release on HST’s scientific work since its launch in 1990. "The combination of Hubble’s longevity due to the astronaut servicing missions, the enthusiasm of the astronomer community to trust us to translate and publicize their results, and the skills, hard work and dedication of our news team has brought us to this record-breaking pinnacle,” explained Ray Villard, STScI’s longtime Public Affairs Manager. "The public never tires of our news stories, which chronicle Hubble's extraordinary science history for future generations.”

We won’t have to wait long for new stories of discoveries related to HST. On New Year’s Day, for example, the New Horizons spacecraft will fly by a Kuiper Belt object known informally as Ultima Thule, which was discovered in 2014 by HST. A week later, a major gathering of astronomers in Seattle will see the release of more science from HST.

The people behind the Hubble Telescope hope and believe that it will still be functioning when its successor, the James Webb Space Telescope, undergoes its scheduled launch in 2021. In any case, the legacies of people like Nancy Roman and Riccardo Giacconi will continue to enrich our knowledge of the universe for some time.

Historians Reconsider Apollo 50 Years Later

Opening session of Apollo Dialogues Workshop from the back of the room. Chris Gainor photo.

On December 7, the NASA History Division and the National Air and Space Museum’s Space History Department held the Apollo Dialogues workshop to discuss spaceflight history today and act as an “incubator” for new work in the field. The workshop took place ahead of celebrations for next year's 50th anniversary of the first human footsteps on the Moon on Apollo 11.

There are not many serious historians and writers who specialize in spaceflight history, and so the 70 participants, including me, who came to the workshop at the Smithsonian Institution in Washington D.C. constituted one of the larger recent gatherings of people working in this area.

 The one-day event was divided into four parts, each starting with a speaker followed by discussions around tables organized by topics such as science, international questions, innovation, society, myths, culture, race, gender, and business. Based on their choice of topic tables, every workshop participant had a unique experience.

In opening the workshop, NASA Chief Historian Bill Barry said he is regularly reminded of the public demand for new views of space history when filmmakers call him asking if historians have produced “the next" Hidden Figures, the book and the 2016 hit movie that told the story of the African American women mathematicians who worked for NASA at the dawn of the space age.

Barry and the other organizers promised “provocative” speakers, and Asif Siddiqi of Fordham University, who is renowned for his work on the Soviet and Russian space program, fulfilled that promise with his opening talk.

Apollo, Siddiqi said, has been “overwritten,” particularly in the form of positivist narratives that isolate Apollo from other events of the time. Apollo was an integral part of the Cold War between the U.S. and the Soviet Union, yet this reality is often ignored in histories of Apollo, both by spaceflight historians who concentrate on the Apollo program itself, and by historians writing on the Cold War who often ignore or marginalize the space race in their accounts.

The history of the race to the Moon needs to move beyond the traditional astronaut- and leader-centred accounts to new and broader perspectives, such as those of the women in Hidden Figures who overcame discrimination to help put NASA's first astronauts into space, Siddiqi said. The history of spaceflight must take more account of power relationships in society and the world.

Finally, he spoke about the impact of Apollo on succeeding space programs that have suffered in comparison because Apollo had set the bar of success so high.

The second speaker, Emily Margolis, a Johns Hopkins University postdoctoral fellow at the National Air and Space Museum, discussed the uses of social media in spaceflight history. While social media can be used to trace popular discourse on space and to obtain historical data, its dynamic nature means that it is far from a permanent record.

Washington Post reporter Christian Davenport, the author of The Space Barons: Elon Musk, Jeff Bezos and the Quest to Colonize the Cosmos, spoke about the challenges of getting information on private space companies such as Musk’s SpaceX and Bezos’ Blue Origin that are taking a larger role in space exploration than in the past when governments dominated this area. Bezos has been very secretive about Blue Origin, Davenport said, and Musk has become famous for his thin skin, and these realities affect what we are allowed to know about their work.

The fourth speaker was Johnson Space Center historian Jennifer Ross-Nazai, who addressed the need to give more prominence to the large numbers of women who made Apollo possible. We now know about the small groups of women who worked to join the ranks of the early astronauts or used their special skills in the space program such as the women of Hidden Figures. But these accounts miss much larger numbers of women who worked in clerical and other traditional female occupations to make Apollo a success, Ross-Nazai said. Another forgotten group is women married to men employed in the space program who supported their work by taking on enlarged family responsibilities.

Many interesting discussions took place at the individual tables during the day. In my case, I joined a discussion of the international aspects of Apollo. I have written about the role of Canadian and British experts in Apollo, and others have covered the German and Soviet aspects of early space programs. But Apollo also benefited from scientific work done in other parts of the world, and the first lunar landing expeditions were followed with great interest around the world and even played a role in the diplomacy of the time.

I also took part in a sometimes contentious discussion about Apollo’s impact on science. Almost all historians agree that Apollo was motivated by a desire to establish dominance in the Cold War rather than to advance science, but the limited scientific work on Apollo led to major findings about the development of the Moon and our solar system, including the Earth. Because much of the knowledge gained from Apollo was subject to scientific dispute for several years, Apollo’s scientific legacy is not as well known as it should be.

The fact that Apollo will soon be half a century in the past means that it is already moving out of living memory. Younger people who were born long after the astronauts returned home from the Moon look at Apollo in different ways from the people who made Apollo happen or followed the news coverage in real time on television.

Back in 1969, many people saw Apollo as a part of humankind’s inevitable march of progress. Today the concepts of progress and exploration are looked at with more skepticism than they were at the time of Apollo. The success of Apollo doesn’t appear as inevitable as it once did. Instead, some scholars suggest that Apollo was a fluke or even a stunt. As we know, many people refuse to believe it actually happened at all. Or was Apollo a twenty-first century event that took place prematurely in the 1960s?

These questions and many others raised at the Apollo Dialogues workshop will provide some new perspectives for historians and writers talking about Apollo in the coming anniversary year and beyond.

The Apollo Dialogues workshop will stimulate our historical work in this area, and it may even generate new and thought provoking historical works about our first steps on another celestial body.
