SpaceX finally had another successful launch, after several scrubs over the past week or two. On Friday, March 4th, a Falcon 9 rocket carrying the SES-9 payload launched from Florida. It was their first launch since January and second of the year. The first stage attempted a landing on their Autonomous Spaceport Drone Ship (ASDS) but had a hard landing.

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.

Veteran cosmonauts Sergey Volkov and Yuri Malenchenko conducted a successful spacewalk on the Russian Segment of the ISS.

It’s been a busy two weeks since my last news post. Among other things, my wife started her “space mission” (not a real space mission) and I won’t see her again for another 26 days. See my last post before this one for some details on what she is doing. I also travelled to Huntsville, Alabama for a work meeting at Marshall Spaceflight Center this week. Now that I am back home and it is just me and the dog, it’s time to figure out what’s been going on out there in the world of spaceflight during the second half of January.

Down to Earth

Probably the biggest news was the successful reflight of the New Shepard rocket by Blue Origin. The same booster that flew suborbital and returned safely back in November was flown again on a similar mission profile on January 22nd. Here’s their shiny video:

SpaceX had some videos too, but not as shiny as exciting. First was this hover test of the new Dragon capsule:

Second was a parachute test:

There were 3 launches since the SpaceX Faclon 9 launch back on January 17th. First was an Indian PSLV rocket, launched on the 20th with one of their own navigation satellites. Second, a European Ariane 5 rocket launched on the 27nd with an Intelsat communications satellite. Lastly, a Proton rocket launched from Kazakhstan earlier today with an Eutelsat communications satellite.

Meanwhile in the category of fluff pieces, someone at Gizmodo has dubbed the Orbital ATK Cygnus spacecraft the “cutest” cargo hauler to the space station.

Aboard the ISS, the Tims are really getting into the swing of things with their Earth photography. Along with Scott Kelly, the stream of pictures on Twitter from the three of them has been quite good, including some good shots of the snow covered East Coast last weekend.

Unfortunately, there may not actually be a planet orbiting in the Alpha Centauri system… or at least, the previous research that hinted at one may be wrong (but who knows, there may be one there anyway).

Fortunately, there is good news to counteract the bad: new mathematical models indicate there may be a new large planet orbiting far beyond Pluto. Astronomers are busy turning on various search campaigns to see if they can find the theoretical world.

This week NASA finally announced the winners of the next Commercial Resupply Services contract, or CRS-2. This is the contract currently held by SpaceX and Orbital ATK to delivery cargo to the ISS. The contract was rebid for flights starting in the 2019 timeframe. NASA made the exciting decision to give the contract to all three remaining companies: SpaceX, Orbital ATK, and Sierra Nevada.

This was a good week for SpaceX, beyond just the cargo award. To get people excited, they released this video recap of their successful launch and landing last month:

Then they performed a “static fire” test of the recovered booster. The results were reportedly good with some anomalies.

And thirdly, SpaceX launched the Jason-3 satellite for NOAA on Sunday from their California launch site. The satellite reached orbit successfully, but the first stage recovery attempt – which was on a barge instead of a landing pad in this case – was close but unsuccessful. Here’s some information from NASA about the Jason-3 mission if you are interested. If you want even more, AmericaSpace has an interview with the Project Scientist.

And here’s some awesome video of the touchdown (I’ll add it as an embedded Vine below whenever it is posted there).

China also had a successful orbital launch today with a telecommunications satellite for Belarus. The SpaceX and Chinese launches are the first two flights of the new year.

Meanwhile, on the space station, the “Tims,” astronauts Tim Kopra and Tim Peake, went out for a spacewalk on Friday to repair one of the ISS power channels that malfunctions last November (while I was on shift, in fact). The EVA was successful in its main objective but had to be terminated early due to unexpected water accumulating in Tim Kopra’s helmet.

Around the Solar System

The European Space Agency attempted to contact the Philae lander, on comet 67P-C/G, but it is still nonresponsive. As the comet gets farther from the sun in its orbit and the light levels decrease, the chance of the little probe waking up are quickly diminishing.

The JUNO spacecraft, on its way to Jupiter, has broken the “distance record” for a solar powered spacecraft, according to Spaceflight Insider.

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.

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.

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:

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.
