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.
Down to Earth
SpaceX posted an update to their accident investigation regarding the rocket that was lost on a launch pad in September. Here’s a direct link to their anomaly updates page. They hope to return to flight this year.
In launches, it has been a slow couple of weeks, with only two orbital launches since my last post on October 16th. It was quality over quantity though, as both launches were important and anticipated missions for ISS operations.
First, Orbital ATK was able to finally launch their upgraded Antares rocket with a Cygnus cargo craft on its way to ISS. The rocket launched on Monday October 17th and was captured at the ISS almost a week later on Sunday the 23rd. The delay was necessary due a higher priority launch and docking of three crew aboard a Soyuz (see below).
On Wednesday, October 19, the Soyuz rocket carrying the second half of Expedition 50 finally launched (after a spacecraft problem delayed them several weeks). The launch, rendezvous, and docking were flawless. The new crew of Shane Kimbrough Andrei Borisenko, and Sergey Ryzhikov arrived at ISS on the 21st.
There were 8 people in space only briefly (recall that two Chinese taikonauts are hanging out on their own space station right now). Expedition 49 had to hand over command to new Expedition 50 commander Kimbrough on the 28th before Anatoli Ivanishin, Kate Rubins, and Takuya Onishi undocked on Saturday night and landed safely a few hours later.
Speaking of the Chinese taikonauts, they docked successfully to the Tiangong-2 space station on October 20th and plan to stay for several weeks.
Around the Solar System
The ExoMars mission arrived at Mars on October 19th. The orbiter (known as TGO – Trace Gas Orbiter) made a successful orbital insertion burn but unfortunately, contact with the Schiaparelli lander was lost at the planned time of touchdown. The lander is suspected to be lost, but NASA’s Mars Reconnaissance Orbiter (MRO) was able to image the lander’s crash site, which should help with investigations. Below is an animated GIF showing the recent appearance of the lander in MRO imagery:
And here’s a closeup from the MRO’s HiRise camera.
In other bad news, the Juno spacecraft went into safe mode during its closest approach to Jupiter on October 18 and was not able to obtain scientific data. This came only a few days after an engine burn had been cancelled. Fortunately, mission controllers were able to command Juno out of safe mode on October 24 and perform at least one “trim” maneuver. The mission timeline will be impacted by the problem but there are still dozens of orbits left in the primary mission to gather data.
Here is a nice post with images about the preliminary results from Juno so far.
Speaking of spacecraft beaming data back to Earth, the data downlink from the New Horizons probe of its Pluto flyby last July has finally completed, 15 months later!
Down to Earth
An opinion piece by Barack Obama appeared in CNN last week discussing his vision for America’s future in space and particularly, future missions to Mars.
Amid talk of a schedule slip of the first Starliner missions, Boeing announced they will need to add an aeroskirt for their launch configuration atop the Atlas V rocket (follow the link for an illustration).
Astronauts on the ISS opened up the BEAM module for another round of inspections (that’s the “expandable” module that was added back in May). Meanwhile, NASA announced that it is seeking commercial partners to build new functional modules for the ISS. Of course, the supplier of BEAM, Bigelow Aerospace, is one of the companies seeking the contract.
The launch of Orbital ATK’s Antares rocket (returning to flight almost 2 years after the last one failed after launch) was delayed until tomorrow evening due to a technical issue.
Earlier this evening, China launched a manned Shenzhou capsule with two crew aboard. They are heading to the new Tiangong-2 space station for an extended mission. When the latest ISS Soyuz crew launches in a couple of days, there will be 8 people in space! It has been very rare for the number to grow above 6 since the last Space Shuttle mission five years ago.
Around the Solar System
Due to some sticky valves in the Juno spacecraft’s propulsion system, the probe will not be making a scheduled burn to reduce its orbital period from over 50 days to just 14 days. NASA is waiting another orbit (so, until December) to investigate and then try again.
Astronomers have discovered a new distant unnamed object (2014 UZ224) which may be large enough to qualify as a “dwarf planet”. The object is smaller than Pluto and orbits about 5 times farther from the sun.
The ExoMars/Schiaparelli mission – a joint mission between ESA and Roscosmos – had some critical mission events today, including separation of the Schiaparelli lander and a critical orbital maneuver to setup for orbital insertion next week.

Early on the morning of May 6, SpaceX launched a commercial communications satellite on a Geostationary Transfer Orbit. The launch was a beautiful and nominal night launch. After Main Engine Cut Off (MECO) the Falcon 9 first stage flew back to the Autonomous Spaceport Drone Ship (ASDS) for another successful landing at sea. Are you not entertained?
Speaking of SpaceX, don’t forget to tune into NASA TV on May 11 for coverage of their Dragon spacecraft departing the International Space Station.
And as usual, the ISS crew has been busy sharing their view on high with us. Here are some stunning recent posts from their Twitter accounts:

The first launch of Russia’s new Vostochny spaceport took place on April 28th. Here are some great pictures via Spaceflight Now. The rocket was carrying two “technology” satellites and one gamma-ray observatory.
In other launch news, India launched a big rocket carrying one navigation satellite, to complete their domestic navigation constellation. And thirdly, ESA was finally able to launch their Sentinel-1B Earth-observing satellite, which was delayed last weekend.
Up on ISS, the Soyuz TMA-19M crew has learned that they will get about an extra two weeks in orbit, as Expedition 47 has been extended to June 18th.
In sad news, JAXA has given up their attempts to recover the stricken Hitomi x-ray observatory which has been out of contact for some weeks. They now suspect that the spacecraft spun out of control due to an attitude control malfunction and lost its solar arrays.
Tim Peake got to do a unique experiment from the ISS last week when he controlled an ESA rover on the ground via remote control.

WIRED sent a guy to spend a day at JSC learning what it’s like to be an astronaut. The short video is fun and probably fairly informative for non-space geeks.
Lots of launch activity in the past two weeks. Of the five total launches, I’ll get the two less interesting ones out of the way first: on March 13, a Russian Earth observation mission launched from Baikonaur and then on March 24, a Russian military mission launched from Plesetsk. Both were on Soyuz rockets.
The other three launches are much more interesting. First, on March 14 the much anticipated ExoMars mission launched on a Proton rocket from Baikonaur. The Mars exploration mission is currently safely in solar orbit on its way to an October rendezvous.
On March 18, another Soyuz rocket launched from Baikonaur, but this time carrying 3 people. Aleksey Ovchinin, Oleg Skripochka, and Jeff Williams had an uneventful launch, rendezvous, and docking with the ISS. Or at least, as uneventful as those sorts of things go!
Lastly, an Atlas V rocket launched from Florida on March 23 carrying a Cygnus cargo freighter. Cygnus, named the S.S. Rick Husband by Orbital ATK, arrived (also uneventfully) at ISS on Saturday morning.
