Some new videos from Blue Origin and SpaceX of their recent rocket successes were released this past week:

The astronaut Kelly brothers, Mark and Scott, had their childhood elementary school named after them this past week.

Two astronauts, Scott Parazynski and Brian Duffy, were inducted into the astronaut hall of fame.

The amazing Thierry Legault has done it again, this time taking a video of the ISS transiting the sun at the same time as the Mercury transit on May 9th.

An unusual parade happened in Los Angeles on May 21st when the last Space Shuttle External Tank was towed from the coast to the California Science Center.

In Orbit

The Indian Space Research Organization launched their new experimental space plane on May 23rd. The uncrewed vehicle actually didn’t make it to orbit, or even to space, reaching only a peak altitude of 65 km. Still, reaching Mach 5 on re-entry is no joke.

The only other notable rocket launch since my last post on May 9th was a Chinese low earth orbit (LEO) reconnaissance satellite launched on May 15.

Around the Solar System

Some recent experiments in a Martian atmosphere simulator have given us an update on the Recurring Slope Linae (RSL), which were announced last year as evidence of flowing liquid water on Mars. It may be that ice boiling directly to a gas may be causing the features.

NASA’s flying telescope, SOFIA, has detected atomic oxygen in the atmosphere of Mars. Atomic oxygen is highly reactive and thus can tell us a lot about what is going on at Mars, potentially even the chance for life.

Speaking of Mars, check out this new image from Hubble. Mars is at opposition this week – or the closest approach to Earth – making it a great target for Earth-based astronomers.

Out There

You probably didn’t miss this story: NASA announced the confirmation of more than 1,200 new exoplanets discovered by the Kepler Space Telescope. This brings the total planets discovered outside our solar system to over 3,300 worlds.

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.

Unfortunately, it sounds like Japan’s Astro-H X-ray observatory may have been lost only weeks after it launched in February.

A number of rocket launches since my last post in late January: a Chinese rocket launched one of their navigation satellites (Beidou), a ULA Atlas V launched a GPS satellite, a Russian Soyuz rocket launched one of their navigation satellites (GLONASS), a ULA Delta IV launched a secret USA reconnaissance office payload, and lastly North Korea launched something.

This brings the worldwide launch cadence for the year up to 10 so far, or almost 2 per week. We are still waiting for the first SpaceX Falcon 9 launch of the year, which should be before March.

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.

Components of ESA’s ExoMars mission have arrived at the launch site in Kazakhstan. Launch is coming up quick in March!

Russia’s space agency, Roscosmos, was dissolved by law this week under the ongoing reorganization of the space industry going on in that country.

Oak Ridge in Tennessee has produced the first Plutonium-238 in decades. This non-weapons grade nuclear fuel is needed for the RTG power sources of deep space missions.

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.

The US federal budget bill for 2016 (referred to as the “omnibus bill”), which has been signed into law by the President, is good news for NASA, with over a $1 billion budget increase for next year.

NASA has confirmed with ESA that the James Webb Space Telescope (JWST) will launch to space aboard an Ariane 5 rocket in 2018. Basically, they signed the contract to pay for the launch. Meanwhile, the JWST mirror installation has been ongoing at Goddard Spaceflight Center (GSFC) in Maryland.

NASA’s next mission to Mars, the InSight lander (not a rover), was delivered to the launch site in California. However, the launch will be delayed, probably about two years, due to an issue with the spacecraft. Here’s the press release from NASA.

NASA ordered a second Boeing CST-100 Starliner flight to ISS. The first crewed mission is expected sometime in 2017.

Other than the InSight delay, the year is wrapping up nicely with some successes. Since my last post on the 13th, there were 6 orbital launches, all successful. The launches included the arrival of the rest of the Expedition 46 crew on ISS, with Malenchenko, Kopra, and Peake aboard. Also an Indian commercial launch, a Chinese dark matter telescope, and a European launch of two Galileo satellites, which is their equivalent to the GPS system.

December 21st was a big day with the last two of those six launches as well as an emergency ISS spacewalk to fix the stuck Mobile Transporter. The spacewalk went fine. Meanwhile, Russia launched a Progress resupply mission to the ISS, which docks on the 23rd, and SpaceX made their return to flight launch of the Falcon 9 rocket with a commercial launch for Orbcomm. In addition to successfully returning to flight and launching the first of their upgraded version 1.2 Falcon 9, the first stage was successfully landed back at the landing site for the first time. Here’s a video:

And here’s some photos of the booster on the landing pad the morning after.

Before the TMA-17M crew left ISS, they helped out Commander Scott Kelly with the capture and berthing of the new Cygnus cargo craft, also known as the SS Deke Slayton. It is a beautiful spacecraft.

In launch news, there were three launches this past week: one Chinese and two Russian. All communication or Earth-observing satellites. One of the Russian launches was a Zenit rocket carrying a weather satellite. This is reportedly going to be the last launch of the Ukranian built Zenit. The other launches were a Russian Proton rocket with a communications satellite and a Chinese Long March 3B/E carrying a communications satellite.

In the coming week, it looks like there may be several more launches, but he most exciting should be the Soyuz crewed launch and then hopefully the Falcon 9 return-to-flight by SpaceX next Saturday. It looks like Russia, USA, and China may be in a race for “most launches in 2015″ as we head into the last two weeks of the year, at least according to this running count from Wikipedia:

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.

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.
