SpaceX successfully conducted the static fire test for their next rocket launch from Pad 39A at the Kennedy Space Center. A Falcon 9 carrying a commercial satellite will liftoff very early Tuesday morning, March 14th.

In Orbit

Only one orbital rocket launch since my last post. A European Space Agency Vega rocket launched the Earth-observing Sentinel-2B satellite from French Guiana on March 7th.

As usual, there are lots of good pictures from the crew on the ISS to share. Here’s a selection.

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:

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.

 

Around the Solar System

NASA’s MAVEN probe in orbit of Mars executed an avoidance maneuver of about 0.4 m/s to avoid colliding with the moon Phobos. That velocity change is small, about on the order of the debris avoidance maneuvers we do with the ISS.

The crew of three Chinese taikonauts finished their 30-day stay aboard the Tiangong-2 space staion and returned to Earth last month.

A planned cargo resupply flight (with no astronauts aboard) launched from Kazakhstan on December 1 on its way to the ISS, but did not make orbit and crashed somewhere in a remote part of Asia. The next ISS resupply is a Japanese HTV vehicle launching next week.

Virgin Galactic continued their flight test program for the new SpaceShipTwo vehicle (named VSS Unity) with a captive carry flight on November 30 and then a glide drop test on December 3. Powered flights should be happening soon, but no specific dates are public. Here’s a photo gallery of the flight test.

In Orbit

Four other rockets launched since my last post on November 16, all successfully placing their payloads in orbit:

The ISS has had a very busy month, notwithstanding the loss of Progress 65. After the last three members of Expedition 50 arrived, they got quickly to work with last-minute packing of the Cygnus freighter, which they released two days later.

Since the Cygnus departure, the crew has been furiously working on their long list of on-orbit experiments. Thomas has someone found the time to tweet every day. Some of his best are below:

A small sample bag from the Apollo 11 mission is at the center of two lawsuits. I’m sure Dr. Jones would agree that it belongs in a museum.

One of the Orbiter Access Arm’s from the Space Shuttle program is now on display at Houston’s Space Center Houston.

Meanwhile, the next generation of crew access arms, for Boeing’ Starliner capsule, was delivered to the Atlas V pad in Florida.

SpaceX conducted a full duration test fire of one of their recovered first stage boosters. Here’s the video:

Google Lunar X Prize competitor, Moon Express, has received approval from the United States government for their private mission to land a rover on the moon.

Vector Space Systems completed their first successful sub-orbital launch.

In Orbit

Speaking of launches, there were four successful orbital flights since my last post. This brings the year’s total to 50 for 50 on orbital launches. For comparison, 2015 had 87 total with 5 failures.

First was an Atlas V launch from Cape Canaveral carrying a secret payload for the National Reconnaissance Office.

Second and third were two chinese launches carrying a new communications satellite and a radar imaging satellite.

Lastly was the SpaceX Falcon 9 launch early in the morning ofAugust 14. The rocket successfully delivered the Japanese JCSAT communications satellite to orbit and recovered the first stage booster on the ASDS at sea. Very impressive. This brings SpaceX’s year up to 8 successful launches for 8 attempts – a yearly record already in August – and 5 for 8 on booster recovery.

Coming up next week is a spacewalk on ISS by NASA astronauts Jeff Williams and Kate Rubins to install the new International Docking Adapter.

SpaceX continues their very successful year with a commsat launch (Thaicomm-8) to geostationary orbit and another successful landing of a Falcon 9 first stage at sea. Here is a timelapse from an onboard camera showing the landing.

Three other successful rocket launches in the last week included a Soyuz launch by ESA carrying new Galileo navigation satellites, a Soyuz launch by Russia carrying a single GLONASS navigation satellite, and a Chinese rocket carrying Earth-observing satellites.

Up on the ISS, NASA successfully completed deployment of the Bigelow Expandable Activity Module (BEAM), which is the first expandable structure to be launched as part of a manned spaceflight program. Astronauts are expected to egress BEAM in the near future.

Not much else happened in space news this week (but really, that’s a lot), so here are some pretty pictures from 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. Here are some of my favorites.

Oh and this was a cool thing from Scott Kelly also:

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.

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.

Blue Origin had a suborbital flight of their New Shepard vehicle. The unmanned capsule landed back on Earth under parachute and the rocket itself landed under its own power on two legs. Here’s the video.

And here’s an awesome video of Blue Origin employees celebrating the flight. Almost as good as JPL celebrating a rover landing on Mars. Way to go guys!

In Orbit

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):
