NASA has finalized an agreement with Boeing to use the extra seats on two Soyuz flights to the ISS over the next year and a half for additional US astronauts. There is some contractual stuff going on here, but basically NASA is going to use seats that Roscosmos was going to leave empty to save money.
Virgin Galactic has spun off its LauncherOne program into a new company called Virgin Orbit.
Jeff Bezos’ company Blue Origin is now getting in on the new moon missions also. According to the Washington Post (owned by Bezos), Blue Origin has floated a proposal to the new US presidential administration that they want to help support NASA missions to the moon with their Blue Moon concept.
PBS News Hour did a brief segment on all of this new interest in lunar missions:
Two rocket launches since my last post:
- United Launch Alliance launched an Atlas V rocket from Vandenberg California, carrying two satellites for the NRO.
- China launched one satellite on their new Kaituozhe-2 rocket.
It’s hard to keep up with the current ISS crew, the members of Expedition 50, as they tweet like its all they do in what little spare time they have. Here’s a selection of the best pictures from just the last week.

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.
If you are interested in just the 4-minute animation from SpaceX showing their imagined Mars mission architecture, jump to the second video below.
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.

Blue Origin achieved an impressive feat last week, flying the same suborbital New Shepard rocket for the third time since November.
Following a rocket anomaly in the launch of a Cygnus resupply craft last month the ULA Atlas V rocket is grounded.
Accomplished NASA astronaut, and current NASA science chief, John Grunsfeld, will be retiring.
Roscosmos is selling the perennially financially troubled venture Sea Launch.
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).

NASA’s New Horizons probe has discovered “methane snow” on Pluto’s mountain peaks.
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.
Close, but no cigar. This time. https://t.co/JowUE6a1D7

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.
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.

Lots of rocket launches since my last post. Here’s a quick run down. I use the Wikipedia page 2015 in spaceflight as a general source (with other references):
Three launches by China of various reconnaissance or communications payloads.
Two launches by Russia, seemingly military in nature. However, the recent launch last night may have had a mishap and part of the payload did not make orbit.
And then Japan, ESA, and America round out the crowd with one more launch each. Japan launched a commercial telecommunications satellite, ESA launched the LISA Pathfinder gravity wave physics probe, and United Launch Alliance sent a Cygnus cargo spacecraft on the way to the ISS for Orbital ATK.
Meanwhile on the ISS, the crew has been posting awesome pictures in whatever free they have. Kjell Lindgren and Kimiya Yui will be coming home this week, on December 11th.

A watch worn by Apollo 15 commander Dave Scott on the surface of the moon recently sold at auction for over one million US dollars. This is not one of the Omega Speedmasters which were given to all the crews (all of which are now owned by the Smithsonian). Instead this was a backup Scott wore when his Speedmaster broke.
An Israeli team called SpaceIL has secured a launch contract on a Falcon 9 rocket for their entry in the Google Lunar X Prize.
Blue Origin announced that it will center its launch operations at Cape Canaveral.
NASA dropped a large archive of photos from Project Apollo to Flickr.
It’s been a busy month of rocket launches. Since my last post on September 26th there have been nine successful launches to orbit: one by India, three by China, one by the European Space Agency, two by Russia, and two by America. Only one of those launches was in support of International Space Station operations: an unmanned Progress resupply mission from Russia. You can see a great list of all launches at “2015 in Spaceflight” on Wikipedia.
In addition to the launches, the Japanese HTV-5 cargo vehicle was successfully undocked and deorbited from the ISS during the last week of September.
Other happenings on the ISS included a debris avoidance maneuver on September 27th, some cubesat deploys, the Progress docking, Scott Kelly breaking the record for most days in space by an American, and some great imagery of Hurricane Patricia.

Science data from the New Horizons flyby of Pluto continue to come in, including this awesome picture showing the blue glow of the planetoids thin atmosphere.
NASA made a big announcement at the end of September about Mars research, revealing that the Mars Reconnaissance Orbiter had imaged evidence of water flowing (intermittently) on the surface of Mars. While previous NASA missions had confirmed that water is present and had flowed in streams and rivers in the ancient past, this is the first evidence of a modern water cycle. As usual, Emily Lakdawalla has excellent coverage.
