Down to Earth

Legendary astronaut Gene Cernan has died at the age of 82. Captain Cernan had an incredible career in the Navy and then at NASA, where he flew on three important missions: Gemini 9, Apollo 10, and Apollo 17. Gemini 9 had Cernan’s harrowing spacewalk (the second for an American); Apollo 10 was the dress rehearsal for the moon landing, in which Cernan and Stafford got to within just miles of the lunar surface before a planned abort; Apollo 17 is of course known as the final mission to the surface of the moon. If you haven’t read Cernan’s autobiography or seen the recent biography about him (both called The Last Man on the Moon) you should put them both on your list.

NASA administrator Charlie Bolden resigned last Thursday – as is tradition for most presidential appointees – the day before inauguration of president Donald J. Trump. NASA is currently being run by acting administrator Robert Lightfoot.

Andy Weir, author of The Martian, announced on social medial that he will be working with CBS on a new show set in Houston’s mission control.

In Orbit

A small Japanese rocket, which would have been the smallest ever to make orbit, failed during a launch attempt last Saturday, January 14th. The rocket was carrying a single small cubesat.

However, two rockets did make successful launches within the last week. First, SpaceX had a spectacular return to flight on Saturday, January 14th, placing 10 satellites into orbit for Iridium after a flawless launch of a Falcon 9 rocket from Vandenberg in California. They even stuck the landing on the first stage recovery.

Lastly, on January 20th, United Launch Alliance launched an Atlas V carrying a USAF satellite, GEO 3.

Meanwhile, a failure investigation has narrowed down the loss of a Russian Soyuz rocket last month to an oxidizer pump, leading the Russian space agency to make some part replacements on both the next manned and unmanned flights. Hopefully we will see Soyuz rockets flying to the ISS again soon!

2016 In Review – Part I

2015 year in review posts: Part I and Part II.

2014 year in review posts: Part I and Part II.

2013 year in review posts: Part I and Part II.

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.

2015 in Review – Part II

Honestly, at the beginning of 2015, I did not think the year could possibly be as interesting as 2014 when it came to the launch sector. I thought there was a possibility SpaceX would achieve some major milestones from its list of goals for the year – maybe recover a first stage, maybe launch a Falcon 9 Heavy, maybe double their flight rate – but probably only one or two of them. I never would have guessed that 2015 could have the same roller coaster ride of ups and downs of 2014, which had rocket launches, rocket explosions, and political tension. Surprisingly, not only did 2015 have me on the edge of my seat like 2014, it surprised me and almost everyone else with some crazy twists and turns.

Part II – Rockets

Let’s recap where we were at the end of 2014: SpaceX had just wrapped up a reasonably successful year with 6 flights and no failures, which was twice the number of flights they had in 2013. The debate over the RD-180 engine was still ongoing but had calmed down somewhat with a congressional budget provision for the US to start working on a homegrown replacement. In the meantime, ULA would be allowed to continue using RD-180s to a limited extent. The biggest event of course was the spectacular explosion of an Orbital Sciences Antares rocket on its way to the ISS. Really the story had all eyes on – and are we really surprised? – SpaceX. With Orbital Sciences grounded and ULA under heat for using imported Russian engines, SpaceX was here to save the day.

And SpaceX certainly got off to a roaring start in 2015. They launched the first rocket of the year, which certainly served to make a point, and from there on averaged one Falcon 9 launch per month through June. During two of those launches in January and April they thrilled everybody with their so close rocket landing attempts. I have to repost the videos again below because they are so awesome.

Meanwhile, while all that fun was going on, the US Air Force granted SpaceX certification for military payloads and SpaceX conducted a launchpad abort test with their Dragon V2 capsule. Things were looking pretty good for the (not so) New Space company. But then this happened during their CRS-7 launch to ISS, their 6th of the year:

Suddenly, things completely changed. Adding another layer to the story, a Russian Progress resupply flight to the ISS had also been lost in late May, after which some people had been saying “good thing we have a SpaceX flight coming up.” Not only was the future of SpaceX’s manifest and Falcon 9 rocket in question, there were serious questions about the logistics chain to the ISS. Three of the vital cargo rockets were grounded, with only the Japanese HTV unaffected.

Thankfully, one of the things the Russians are really good at is rebounding from launch failures, and they flew a successful Progress mission to ISS only a few days after the SpaceX explosion. Regardless, 3 of the last 8 unmanned flights to ISS had been lost, an unprecedented statistic.

Orbital ATK (the new name of Orbital Sciences after a merger early in the year) had already announced plans for their return to flight way back in January. Surprisingly, their strategy would be to purchase launch vehicles from their competitors to fly their Cygnus freighter while they worked on a redesign of the Antares first stage. The return to flight would be on a ULA Atlas 5 sometime late in the year. The good news for all involved is that that launch went off without a hitch (after some weather delays) in mid-December. The Cygnus freighter known as “SS Deke Slayton” is happily berthed to the ISS as I write this.

As for SpaceX, all plans for a Falcon Heavy launch, a rocket landing, or a new record flight rate, were taking backseat to the job of figuring out why their rocket had disintegrated on them. Second priority was getting a return to flight scheduled ASAP to pick up their deep manifest (which was already stacked pretty deep coming into 2015). It came out very quickly that the mishap was caused by the failure of a strut, or a structural beam, holding a high pressure helium tank in place. Unfortunately, just because you know the cause of a failure doesn’t mean you know how long it will take to sort out the problem and get back to regular launches. For the next few months it was unclear to the public outside SpaceX if they could even return to flight within the calendar year.

Meanwhile, the rest of the world kept launching rockets. ULA in particular had a pretty good year with 12 launches and no failures. Even though ULA’s Atlas and Delta rockets are extremely successful and don’t really need replacing, they responded to pressures both from the government (which was saying stop using Russian engines) and SpaceX (who is threatening to change the launch industry entirely with reusability) and revealed plans for their new Vulcan rocket. The Vulcan is an ambitious new project which will take at least 5 years to complete. It will use a new American built liquid stage engine and aim to save money by recovering those engines after every launch. Their plan is kind of crazy, as it involves a helicopter. Here it is graphically:

Then in November ULA made space news headlines by not bidding on a GPS satellite contract from the DoD, essentially ceding the launch to SpaceX. ULA listed a couple of reasons they felt that it was not really worth their time to bid, including the Congressional mandate against them to not buy any more RD-180s from Russia. ULA was basically saying, we don’t have enough engines. John McCain in particular was not amused. McCain, who is strongly against the import of Russian rocket engines, feels that ULA has more than enough RD-180 engines already in stock without buying new ones from Russia. They simply need to allocate less engines for commercial and NASA launches and more to DoD payloads. The move was basically a bluff from ULA to get people talking, and it has yet to be seen if it will work.

Which brings us to the tail end of the year, with two of the biggest surprises still left. While everyone was busy talking about SpaceX, Orbital ATK, and ULA, Blue Origin came out of nowhere with a pretty spectacular flight demonstration of their New Shepard rocket. The secret launch occurred in their West Texas facility, reaching the edge of space before the capsule safely came back to Earth under parachute and the first stage touched down vertically under power.

On the face of it, it appears Blue Origin had swooped in and accomplished the first real first stage recovery after a functional rocket launch, right from under SpaceX’s nose. In reality, the technical challenge involved with Blue Origin’s feat is somewhat different than what SpaceX had been trying to do, as the below graphic illustrates. Blue Origin’s launch – while impressive – was suborbital. Meanwhile, SpaceX had been trying to bring back a first stage from a rocket that was actually putting payloads into orbit, which requires much higher velocity.

Regardless, Blue Origin is clearly the quiet dark horse in this story. They almost stole the limelight this year, at least that’s the way it looked before SpaceX stole it back just 9 days before the end of the year. Less than 6 months after their failure, SpaceX launched a Falcon 9 on December 22nd, placing a fleet of Orbcomm satellites into orbit and, to everyone’s amazement, successfully landing the first stage back at “Landing Zone 1″ at Cape Canaveral.

This made the mishap back in June look like small potatoes. SpaceX had just achieved one of those three big goals for the year. While there is still a lot of work for them to do to checkout the rocket and determine how much refurbishment would be needed for reflight, this was a major step towards their goal of reuse. Not only that, but being back on flight status puts them in a great posture going into 2016 ready to fly out a big part of their deep manifest. They also likely now have the focus and resources to get that first Falcon Heavy in the air this year.

2016 looks good for Orbital ATK too – with a second Cygnus flight on an Atlas 5 coming up quickly in March and then the maiden flight of their upgraded Antares rocket in May. Overall, the year ended on a high note for the launch industry, with many space fans pretty optimistic. Given how things were looking back in the summer, this year could have turned out quite differently. Losing a Progress cargo craft, which is the only source of fuel resupply and propulsive support for ISS, is always a big deal at NASA and it spins up contingency planning. Fortunately, we ended the year with not just Russia but everyone having returned to flight. Not only do we have a solid reliable supply chain re-established to ISS, lots to look forward to from SpaceX, and resumed orbital flights from Virginia, we are also getting tantalizingly close to the first test flights of the Dragon V2 and Boeing CST-100 manned spacecraft.

I had my heart in my throat for a bit this year, but ended up jumping up and down and cheering with everyone else on December 22nd. It was exciting and all, but after the last two years I’m ready for less drama, and more launches. Ad astra.

2015 Summary Link Dump

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!

Wikipedia Stats

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.

Here are some new high resolution images from the SpaceX booster flyback landing last week.

And here is a nice shot of the booster being returned to the SpaceX launch complex.

United Launch Alliance has ordered more of the RD-180 engines that power its Atlas rockets. This is the Russian-built engine that has been causing political controversy since early 2014, since American politicians understandably don’t want our military satellites dependent on a geopolitical adversary’s technology. The new engines are only planned to be used for civil and commercial launches.

Meanwhile, the USAF awarded a bunch of money to several companies for propulsion development so that RD-180s won’t have to be purchased in the future.

Only two launches since my last post on December 22nd: a Russian Proton rocket* with a communications satellite and a Chinese rocket with an Earth observation satellite. With no apparent planned launches for the rest of the year (according to my favorite Wikipedia page), that leaves the yearly totals as seen below, with Russia at 25 successful launches and China and the US tied at 18. If SpaceX had launched as many Falcon 9s as they had hoped this year, then the US may have matched or surpassed Russia’s numbers for the first time since probably 2003*. Comments from Musk at a recent press conference indicate he hopes for 12 launches in 2016. We will see.

Screen shot 2015-12-28 at 10.45.06 PM

*The Proton is the rocket that seemed to blow up every other launch a couple of years ago. Although there has been only been one failure every year since 2012, the failure rate has remained about the same since 2010, with 4 out of 32 launches failed 2010 to 2012 and 3 out of 26 from 2013 to 2015.

**In 2003, Orbital Sciences was operating the Pegasus rocket (four launches), ILS was launching out of both Florida and Kazakhstan (I counted based on launch site) and Boeing and Lockheed had yet to merge as ULA. USA outscored Russia by 23 to 21 that year by  my count.

I love this animated mission update on the Rosetta/Philae mission from ESA.

New analysis indicates that Mars’ small moon Phobos may only have millions of years to live. Due to its low orbit, it is getting torn apart by tidal forces, which cause the strange “grooves” on its surface.

New images of large mountains on Pluto may be evidence for “ice volcanoes” (or “cryovolcanoes”).

Check out this animation which shows the different spin rates of Pluto’s 5 moons.

Astronomers have discovered a new distant solar system object which may be the most distant rocky body known. V774104 is about half the size of Pluto and orbits several times further away.

Out There

Newly discovered planet , GJ 1132b, is the closest planet of about Earth’s size yet discovered, at only 39 light years distant. Unfortunately, the planet is tidally locked and very close to its star, making it not a fun place.
