There have been only two orbital rocket launches since my last post on March 28th:
The first launch was a much-anticipated flight from SpaceX. The launch on March 30th was a relatively routine launch of a communications satellite to geosynchronous orbit. What made it unique was the the first stage of the Falcon 9 rocket had previously been flown before on a NASA cargo launch last spring. The launch was flawless, including recovery of the first stage booster on the droneship at sea, marking the first operational reuse of a rocket by a commercial company (components of the Space Shuttle system, such as the Orbiter and the SRBs, were frequently reflown).
The second launch was a Chinese Long March 3B rocket with a communications satellite aboard. This launch was mostly notable for this incredible video of the launch filmed from a dangerously close range:

Meanwhile, things have been very busy at the International Space Station. Astronauts Shane Kimbrough and Peggy Whitson conducted another spacewalk (designated US EVA 41) on March 30th. The pair of experienced spacewalkers managed to complete all planned tasks, including hooking up a new docking port at the front of the space station. However, the EVA was not without some excitement: one of four special thermal “shields” was accidentally dropped overboard and mission control teams had to come up with a plan to replace the shield in order to keep components of the ISS thermally protected.
Shortly after the spacewalk, Commander Shane Kimbrough handed the space station over the Whitson and then returned to Earth with the rest of his Soyuz crew, completing Expedition 50.
It was then announced that Peggy Whitson has agreed to stay onboard the ISS an extra 3 months and use a bonus empty seat on next week’s Soyuz mission to come home in September. Peggy will be the most experienced non-Russian astronaut in history when she comes home.

New results from the Cassini spacecraft, which orbits Saturn, have shown that the “plumes” coming from the ocean moon Enceladus’ subsurface seas contain molecular hydrogen, which could be used by microbial life to conduct methanogenesis (like the life living near Earth’s deep sea hydrothermal vents).
Measurements of elemental argon in Mars’ atmosphere by the MAVEN spacecraft have revealed that most of the planet’s atmosphere has been lost to space.

SpaceX’s latest Dragon capsule left the ISS on March 19th and was successfully recovered by the company at sea.
A new exhibit about Valentina Tereshkova, the first woman in space, has opened at the Science Museum in London.
The White House released their budget proposal for 2018, including proposed spending on NASA. The proposal funds NASA at $19.1 billion, which is a slight cut. Taking into account inflation, it comes out to a few percent less than what NASA is working under in 2017. If you really really love reading about budgets, here is a super long post from Casey Dreier at the Planetary Society breaking down the proposal.
The European Space Agency is having trouble with their only orbital launch site down in French Guiana as a general strike is causing most of society in the small French territory to grind to a halt. There had been an Ariane 5 rocket launch planned for last week that continues to be delayed.
There have been three successful orbital rocket launches since my last post on March 12th:
- March 16 – a SpaceX Falcon 9 rocket launched the Echostar 23 satellite. Because it was headed into geostationary orbit, the rocket’s first stage was not recovered. The upgraded “block 5″ version will have enough power to be recovered on all missions.
- March 17 – A United Launch Alliance Delta IV rocket launched a USAF communications satellite into geosynchronous orbit.
- March 19 – A Japanese H-IIA rocket launched a reconnaissance satellite into LEO.
Meanwhile, SpaceX is working towards their next rocket launch. The next Falcon 9 rocket will be a commercial launch of the SES-10 communications satellite. The exciting part of this mission is that it will be the first flight of a reused first stage booster. The static fire test was completed today, with launch scheduled for Thursday evening.
On the International Space Station, the Expedition 50 crew is very busy with a series of spacewalks that will serve as Commander Shane Kimbrough’s send off before he comes home in early April. The first spacewalk was conducted last Friday, March 24th, when Kimbrough and Thomas Pesquet spent six and a half hours outside conducting various repairs and upgrades.
One of the spacewalk’s tasks was to disconnect Pressurized Mating Adapter 3 (PMA-3) before it was robotically moved this past Sunday to its new home on top of Node 2 for future dockings of the Dragon and Starliner spacecraft.
The next spacewalk is this coming Thursday. here is an hour long briefing from last week that describes the spacewalk plans in detail (keep in mind the discussed arrival of the Orbital ATK Cygnus cargo craft has since slipped):

Down to Earth
During a media conference call on Friday, NASA managers provided some details about the potential plan to put astronauts onto the first test flight of the new SLS rockets. In particular, they stated that they would look at putting a crew of 2 onto the EM-1 mission for a 9-day loop around the moon (the baseline EM-1 mission is a 31-day mission, including a period in lunary orbit). The study should be completed in the Spring.
And then, on Monday, SpaceX held its own media conference call to announce plans to send a Dragon 2 capsule on a very similar trajectory to the revised crewed EM-1 mission. The plan would send two paying civilian astronauts on a trip around the moon next year. Welcome to the new space race?
Virgin Galactic had another glide flight of its new SpaceShipTwo spaceplane last Friday.
The popular movie Hidden Figures, which tells the story of three women mathematicians and engineers who worked at NASA in the 1950s and 1960s, had three nominations for the Academy Awards on Sunday, but did not win any. During the award show, Katherine Johnson, one of the women on which the movie is based, was invited on stage.
Speaking of movies, check out this new theatrical trailer for Mission Control, a movie based on the book Go, Flight! by Rick Houston.
And here’s one more fun video before we move on to actual news that happened in space. Check out this segment Stephen Colbert did on his visit to Boeing’s facilities at Kennedy Space Center.
There was only one orbital launch since my last post: On Thursday, February 23 Roscosmos launched a Soyuz rocket carrying a Progress cargo spacecraft headed to the International Space Station.
That Progress spacecraft arrived at the ISS a day later without issue, less than a day after the SpaceX Dragon capsule – launched on Sunday, February 19th – was captured using the Space Station’s Canadarm 2. Here’s a timelapse of what it looks like to conduct that operation from inside the Cupola module.

While the Dragon rendezvous on Thursday was flawless, it came a day after a previous attempt had to be aborted due to an issue with relative GPS navigation with the space station.
NASA announced on Wednesday that the Spitzer Space Telescope had confirmed the existence of 7 small rocky worlds (similar in size to Earth) around the star TRAPPIST-1, which is 40 light years away.
Part I – Exploration
Spaceflight, as a many-hundred billion-dollar sector, is a broad and complex industry. Even if we focus in on “exploration” – which is the primary focus of this blog – so that we can ignore military and commercial uses of Earth orbit, we are still left with a global list of activities, studies, missions, and companies. This means there is a lot of stuff going on. 2016 was a busy year with many exciting missions from several different countries. This diversity is great, but makes it hard to boil down the events of last year into a coherent story. Even within NASA, we have the ISS program, with its own highs and lows, and the totally separate and just as successful planetary science portfolio of missions. Those missions keep on going, regardless of whether the most recent cargo delivery has made it to our astronauts in orbit, for instance. Meanwhile, in China, the CNSA is continuing to grow as a nascent space power with new rockets, new launch sites, and a brand new space station. Then there’s Russia, Japan, Europe, India, and more. If any theme can be found at all in the events of last year it is that space exploration continues to be a diverse and global endeavor. Putting any nationalism aside, this should give us hope that despite the ups and downs of the economies or space budgets in any given country, that exciting times lie ahead.
It’s hard to start a summary of 2016 in spaceflight without acknowledging that the United States had a major election, with a new President to be inaugurated this week. Any presidential transition leads to uncertainty in the future of government programs, including NASA. Often election years leave the federal government in a continuing resolution. A continuing resolution means that Congress has yet to pass a budget for the year. This leaves NASA and other agencies working under last year’s budget levels, with no increase for inflation or otherwise. The election was a big story for the country in a lot of ways, but NASA and its programs are most likely to feel the effects in 2017, as it tries to continue with business as usual as it waits for new priorities and a new budget.
While 2017 may bring about change (or not), 2016 was another good year for NASA’s flagship space exploration missions. NASA had no major failures last year, just the usual hiccups and challenges (space is hard, after all) and even launched a new planetary exploration mission: OSIRIS-REX, which is on its way to visit an asteroid in 2023. In fact, last year showed that NASA is still a clear leader in planetary exploration, with probes in action all over the solar system. The NASA fleet at Mars remains strong, with two rovers on the surface and two probes in orbit. New Horizons received a mission extension and is on its way to a Kuiper Belt Object rendezvous in a few years. Meanwhile, the probe Juno made orbit at Jupiter and started scientific observations. Unfortunately, Juno has some sticky propellant valves and missed some of its early science orbits when it entered “safe mode.” Fortunately, the probe was brought out of safe mode and completed a Jupiter flyby in December. Most of the probe’s 20-month mission is ahead. Hopefully Juno’s worst days are in the past! Out at Saturn, NASA is still operating the Cassini probe, which has been in orbit since 2004. Sadly, 2017 will see the end of Cassini, as it destroys itself in dramatic fashion, with a dive into Saturn’s atmosphere.
Two other planetary missions of note from other countries had some action last year. ExoMars (a joint mission between ESA and Russia) launched and made it to Mars. However, its companion lander, Schiaparelli, was unable to make it safely to the Martian surface and crash-landed. Thus, NASA remains the sole space agency to have safely brought a spacecraft to the surface of Mars… having done so seven times. Of course, we shouldn’t forget that the Soviet Union is the only country to have ever landed a probe on Venus! A feat which has not been repeated since 1982, and does not appear to be repeated any time soon, as most space agencies focus on asteroids and the outer solar system in their planetary science missions. Venus is not forgotten though, as Japan was able to begin doing science with their Akatsuki orbiter at Venus last year.
Following the theme of “space is hard,” Japan had a pretty devastating failure when their new X-ray telescope Astro-H, or Hitomi, went out of contact after reaching orbit. Fortunately, Japan already has a strong space program and seems mature and professional enough to learn from their mistakes – they released a failure report very quickly after the accident. They currently have an asteroid sample return mission, Hayabusa 2, en route to its target in 2018, which we should all be very excited about. NASA has a strong relationship with JAXA, and will be curating the Hayabusa samples here at the Johnson Space Center when they return.
In human space exploration, the story continues to be the International Space Station. The ISS had an exciting year, partly because NASA and ESA continue to send charismatic astronauts who manage to make the mission feel very personal to all of us following back on Earth. It was a great year for following astronauts on Twitter, including Jeff Williams, Kate Rubins, Tim Kopra, Tim Peake, Scott Kelly, Shane Kimbrough, Thomas Pesquet, and Peggy Whitson. It’s hard to see how this trend will do anything but accelerate, as it’s a cheap and easy way for NASA to connect with the American public and share its mission. Scott Kelly of course returned from space early in the year and retired from NASA on a high note. Since the “year in space” was such a success, both operationally and as a public affairs bonanza, it seems likely NASA will want to try more longer duration expeditions in the future.
On the more nuts and bolts side of things for the ISS, all major mission events went well last year, with both the arrival and installation of the new IDA2 docking adapter and the Bigelow Expandable Activity Module (BEAM). BEAM is an exciting demonstration of where human habitability in Earth orbit may be able to go in the future with inflatable structures. It is exciting to think that the technology may spinoff a private-public partnership with either or both of the companies Bigelow and Axiom to expand the ISS with new large inflatable modules in the future.
The ISS did face some minor setbacks of its own, although not quite as dramatic as in more recent years. Two rocket failures impacted ISS logistics: the SpaceX explosion on the pad in Florida in September and the loss of a Russian Progress resupply mission in December. The good news for NASA was that the SpaceX failure was not an ISS mission, but it meant a delay to the next planned resupply flight of a Dragon capsule, now scheduled for February. ISS is well stocked on supplies thanks to a Japanese resupply mission that also flew in December and the Orbital ATK Antares rocket returning to flight status in October. Even with both Japanese and American rockets able to keep ISS supplied, having the Russian Soyuz rocket family grounded must always make mission managers uneasy. After all, it is the same rocket family that failed in December that also delivers crews to the station. We are not in uncharted territory, as expedition schedules were in limbo after similar accidents in 2011 and 2015. But the ups and downs of the launch vehicle sector are a continual challenge not only for NASA’s ISS program but for dreamers who envision hundreds of people at a time into deep space for colonization. ISS truly is the foothold where we must learn first, and is a great proving ground for those dreamers.
The ISS accounts for over 2,000 person days of space experience a year. The day-in and day-out slog of operating an aging orbital laboratory and learning to live there is slowly but surely preparing us for what comes next. This experience is shared by a partnership of 15 nations (USA, Canada, Russia, Japan, and 11 countries from ESA). However, the rising nation of China finds itself on the outside. Just like in many other sectors, China is finding its own way in space. Last year was a good one for the China National Space Agency (CNSA). Not only did they launch a brand new space station, Tiangong-2 and send a crew of 2 on a 30-day mission to the outpost, they also debuted a brand new Long March 5 heavy lift launcher while matching the US in successful launches on the year – twenty-two. A new medium-lift rocket, Long March 7, also debuted from a new coastal spaceport on Hainan Island, which should give CNSA more flexibility. CNSA’s recent white paper publically published outlining their five-year plan shows ambition but also should be a douse of cold water on people expecting a space race between China and the USA. China certainly has a lot to be proud of as only the third independent nation to place humans in space. But they have a long way to go to put themselves on par with the modern space programs in America and elsewhere. I look forward to their planned lunar sample return mission in 2017, which will give them a lot of “street cred” if they pull it off!
Obviously these are not the only happenings in space exploration and related science areas. I could go on about the exciting developments in exoplanet astronomy, a field that may provide worlds to explore decades or centuries from now, for example. We continue to live in a golden age of space exploration that started with the Galileo probe to Jupiter in the early 90s. For me, 2016 was a testament to the true diversity of the state of space exploration and should serve as a reminder to avoid tunnel vision. There are many facets to how we explore. It’s not just about shiny new rockets and capsules and astronauts, but its also not just about gathering science through a space telescope or a distant robotic probe. All these pieces fit together to move forward the state of our knowledge about the universe together. One of my favorite examples of this from last year was astronaut Kate Rubins’ work on gene sequencing while aboard the ISS. Talk about two sectors that do not traditionally intersect, at least not in the minds of the general public. Diversity – both in the space agencies doing the exploration as well as the type of exploration – will keep the dream alive. I can’t wait to see what we do on ISS this year but I also look forward to news out of China and India as they learn what it takes to fly in space.
The biggest problem with keeping up this steady cadence of exploration is how all these space agencies will pay for it, as the world faces challenging fiscal and security issues. Space is exciting – and important – but it is far from the first priority when it comes to setting budgets in most parts of the world. Fortunately, we have disruptive new players in the launch sector that can help us keep costs down. More on that in my next post.

Jack Garman, who worked a support console for Apollo guidance and navigation, passed away on September 20th, at 72 years old. Garman is best known as being instrumental in the calls to proceed with landing on Apollo 11 when some guidance computer program alarms showed up at just 3,000 feet above the surface. Here’s the raw audio from that part of the landing which is always worth listening to again. Great example of flight control in action.

One of the biggest national stories of the last week was Hurricane Matthew, which came close to dolling out a devastating blow to the East coast of Florida. Fortunately, the most dangerous winds stayed offshore as it passed the Kennedy Space Center, resulting in some damage but nothing too serious.
In the battle of the New Space giants, there were two big stories in recent weeks. First, SpaceX CEO Elon Musk had his much anticipated presentation at the International Astronautical Congress (IAC) in Mexico. the speech presented a high level framework of his plans to visit Mars. Most of the details were focused on the rocket design and less on how humans would survive and thrive on Mars. Below is the full length video, but Ars Technica had a good analysis if you don’t want to watch all of it. Another good take on it from Phil Plait here.

The other big story was Blue Origin’s successful in-flight abort test of their New Shepard rocket (personally, I am not sure if they have a separate name for the capsule or if New Shepard refers to the whole system. It was a pretty exciting launch and test. Jump to 51 minutes in the webcast replay below to watch!
Lots of good news regarding the ISS flight manifest. The next Cygnus cargo freighter, launching from Virginia for the first time in 2 years on Orbital ATK’s redesigned Antares rocket, should fly next Thursday, the 13th.
The following week, the next crew should launch on their repaired Soyuz craft. That launch is scheduled for Wednesday, the 19th.
There were two rocket launches since my last post. First, an Indian GSLV rocket launched a slew of satellites into orbit, including some from Algeria, USA, Canada, and India. Second, an ESA Ariane 5 rocket launched two communications satellites to a geosynchronous orbit on the 5th.

NASA announced new findings from the Hubble Space Telescope that reinforce the conclusion that not only does Europa have a subsurface ocean of liquid water, but that the water regularly exits the moon in powerful plumes (which could be theoretically sampled by a visiting probe).
In even more exciting planetary science news, NASA announced new analysis of data from the MESSENGER spacecraft (which finished its Mercury orbital mission last year). By analyzing imagery from the last part of MESSENGER’s mission, when it was at a lower altitude, scientists have concluded that the surface shows signs of recent contraction, meaning that Mercury is tectonically active.
ESA’s Rosetta mission ended on September 30th with a controlled descent into comet 67P/Churyumov/Gerasimenko.

There have been 4 orbital launches since my last blog update on March 27. Here they are in chronological order: China launched a single Beidou navigation satellite on March 29, Russia launched a Progress resupply craft from Baikonaur on March 31, China launched a microgravity science payload on April 6, and of course SpaceX launched a Dragon resupply capsule on April 8.
The flawless Falcon 9 ascent and capsule deploy was overshadowed by SpaceX achieving the impressive feat of recovering the rocket’s first stage on the ASDS, out in the Atlantic Ocean. This video says it all.
This delivery of cargo aboard Dragon will wrap up a very busy time period aboard ISS. Starting with the Soyuz undocking at the beginning of March, which brought Scott Kelly home and started Expedition 47, there have been 6 different visiting vehicle events, with Dragon being the third cargo resupply in 2 weeks.
One of the payloads aboard Dragon that everyone is excited about is the Bigelow Expandable Activity Module, or BEAM. Here is a simple infographic about BEAM (via Parabolic Arc).

The last year was full of spacey goodness. Some things were expected – even long anticipated – like space probes Dawn and New Horizons arriving at their targets. Other things were a complete surprise, like the loss of SpaceX’s seventh commercial flight to ISS and the discovery of flowing water on the surface of Mars. All-in-all, there was a lot to follow and talk about. Thus, I am putting together one or more “year in review” blog posts to give my perspective on what has happened and what’s to come. In the meantime, you can enjoy other people’s thoughts of 2015 in spaceflight through the links I have gathered below. Happy new year!
As usual, I love to lean on the “year in spaceflight” pages on Wikipedia. The folks that put these together do a thorough job. If we look at the 2015 in spaceflight page, we see that the human race is maintaining our high flight rate, with 82 successful orbital launches out of 87 attempts. These numbers have been steadily growing for years. Here is the last decade’s successful launches numbers, starting with 2005: 52, 62, 63, 66, 73, 70, 78, 72, 77, 88, 82. As I wrote in last week’s Weekly Links post, Russia had the most launches with 26 and their Soyuz rocket is by far the most dominant, at 17 launches. However, their two failures this year make it hard to call Soyuz both the most dominant and most reliable. China launches 19 of their Long March family of rockets with no failures.
Using the “list of spaceflight records” we can see some changes in the list for total time in space. Most notably, Gennady Padalka spent 167 days on ISS during Expedition 43/44, his 5th spaceflight, to put him at the top spot for most spaceflown human ever. He has spent 879 days of his life in space. Also notable is Anton Shkaplerov, who returned to Earth during Expedition 43 and is at the 32 spot, Oleg Kononenko, who returned during Expedition 45 and holds the 13 spot with 533 days, and Yuri Malenchenko and Sergey Volkov who are currently in space and hold the 7 and 31 spots respectively.
The other notable record that was broken this year is “longest single flight by a woman” (which is on the list of spaceflight records page), broken this year by Samantha Cristoforetti, partly because her crew got stuck on ISS a little bit longer after the loss of a Progress resupply flight in May.
