On Mars, the Curiosity rover has driven right up to a 13 foot tall sand dune and is sending us some pretty cool pictures.

Also on Mars, the long-lived Opportunity rover is celebrating 12 Earth-years on the surface.

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.

Down To Earth

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.

In Orbit

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.

In Orbit

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.

A “topping off” ceremony was held at Space Launch Complex 41 in Florida, which will be the launchpad for the Boeing “commercial crew” capsule that will send astronauts to the ISS.

The crew of Soyuz TMA-17M undocked from the ISS and landed back on Earth this past Friday. Here’s a cool shot of the landing site after the recovery team had arrived (click to see larger on Flickr).

The crew of Oleg Kononenko, Kimiya Yui, and Kjell Lindgren were in good spirits upon extraction from their capsule, despite the subfreezing temperatures on the Kazakh steppe.  Here are some shots of them smiling just after touchdown (yes, I’m calling that a “smile” from Oleg).

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:

Researchers with the Dawn mission, in orbit of dwarf planet Ceres, believe that the “bright spots” on the asteroids surface could be caused by salty water which makes its way to the surface and then sublimates.

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. I will miss their Twitter posts! You really should be following them on Twitter yourself, but here are some of their best (it may look like a lot but this is really a small selection from just the last three weeks):

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.

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.

The current head of JPL for 15 years, Charles Elachi, is retiring. Here’s a brief but good interview with him from Pasadena Star News.

NASA has delayed its decision to award ISS cargo flight contracts starting in 2018 until next year. The current contracts being fulfilled by SpaceX and Orbital Sciences run out in a few years and 5 companies have submitted proposals for the new award (SpaceX, Orbital, Sierra Nevada, Boeing, and Lockheed Martin).

NASA will be accepting applications for a new class of astronauts starting December 14th.

Scott Kelly and Kjell Lindgren completed their second of two planned spacewalks during their ISS mission this past Friday.

In orbital rocket news, China had two launches last week: first, a communication satellite on November 3rd and a military reconnaissance satellite on November 8th, bringing their total on the year to 14 with no failures. For comparison, the USA is 16 for 18, Russia is 19 for 21, and ESA is 7 for 7.

A new US Air Force rocket, intended for small payloads, was supposed to reach orbit from the Hawaiian Island of Kauai last week, but had an anomaly on ascent and was lost.

Newly-announced findings from NASA’s MAVEN spacecraft are helping scientists determine what happened to Mars’ atmosphere. Mars has no powerful magnetic field like Earth, so it is suspected that the solar wind has been blasting Mars’ atmosphere away into space over the eons.

There was a workshop in Houston last week for technical discussion about selecting future landings sites for missions to Mars. It may seem a bit premature, with NASA saying missions to Mars won’t occur for 20 years, but engineers would like to take advantage of the excellent capabilities of the Mars Reconnaissance Orbiter to get early high resolution imagery of potential targets.

The US Congress passed a federal budget bill that avoids “continuing resolution” levels of funding for the rest of Fiscal Year 2016. The appropriations negotiations for specifics, like how much money NASA will receive, is not yet decided, but generally a budget provides more flexibility than a continuing resolution. Bottom line is that space policy fans have to wait to see how their favorite NASA programs are affected, but this is hopefully good news.

Check out this article at The Atlantic that does a good job of explaining the complexities and nuances in the political battle over the construction of the Thirty Meter Telescope on Maunakea in Hawai’i.

In rocket news, only one Chinese launch along with the launch of a new GPS satellite from Florida this past week. The next launch to the ISS will be a Cygnus resupply on top of an Atlas V rocket in early December. Later today, the first orbital launch from Hawai’i’s island of Kauai will take off from USAF’s Pacific Missile Range Facility.

Up on the ISS, astronauts Scott Kelly and Kjell Lindgren got to go on their first EVA ever! The EVA had a variety of tasks (it was in fact referred to here at mission control ambiguously as simply the “ISS Upgrades EVA”). The guys get a second walk outside later this week on Friday, November 2nd.

Meanwhile, on November 2nd, NASA marked 15 continuous years of habitation onboard the ISS.

The Cassini spacecraft conducted one of its closest flybys of Saturn’s icy moon Enceladus, passing within 30 miles of the surface and flying right through the “plumes” of water ice flowing out from the subsurface ocean.

A recent astronomical study of Europa – an icy moon of Jupiter with an ocean, much like Enceladus – revealed areas on the surface that appear to have a unique composition, probably caused by the sea water mixing with the surface ice.

A very large asteroid (2,000 feet) called 2015 TB145 flew past Earth this past weekend at a distance of about half a million kilometers. Heres a radar image of the rock; here’s some videos of the flyby.

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.
