Space and astronomy news
Just before dawn on Wednesday (Nov. 26), a pilot in Belgrade caught this stunning video of a “huge number of glowing pieces of whatever” breaking up in the atmosphere above.
You know what this is? A rocket, most likely! It’s the upper stage for the Soyuz that launched three people to space on Sunday (Nov. 23), the European Space Agency says.

Mars isn’t the only place in the Solar System that was busy this week with arriving spacecraft. While NASA’s MAVEN and ISRO’s MOM arrived in orbit around the Red Planet, the International Space Station also welcomed two arriving spacecraft, bringing the total of docked ships at the ISS to five.
Last night, the Expedition 41/42 crew arrived — peeling in on one solar panel on their Soyuz TMA-14M — with the first female cosmonaut to be part of an ISS crew, Elena Serova along with her crewmates cosmonaut Alexander Samokutyaev, and NASA astronaut Barry Wilmore. They took the Soyuz “fast track,” arriving at the station in just under six hours after launch. One of the craft’s solar panels jammed and couldn’t deploy, but the crew docked to Poisk docking compartment without indecent.
The arrival of Wilmore, Samokutyaev and Serova returns the station’s crew complement to six. Already on board are Commander Max Suraev of Roscosmos, Reid Wiseman of NASA and Alexander Gerst of the European Space Agency. They have been aboard the complex since May.
Suraev, Wiseman and Gerst will return home in November. At that time, Wilmore will become commander of the station for Expedition 42, and the remainder of the Expedition 42 crew will arrive in a new Soyuz.
Earlier this week, on September 23, the SpaceX Dragon capsule arrived with over 2.5 tons of science experiments and supplies for the crew.
Also docked to the space station is the Soyuz ship that will take Suraev, Wiseman and Gerst home, a Progress resupply ship and the European ATV-5 supply ship.
There are two more cargo missions targeted to launch to the space station before the end of the year. Orbital Sciences just announced October 20 as the next launch date for their Cygnus commercial space freighter. It will occupy the same Harmony node port as Dragon when it leaves in a few weeks. When Cygnus vacates the Harmony node port, SpaceX CRS-5 will replace it in December.
Wow! See that bright streak in the photo above? That’s a shot of the Expedition 40 crew making a flawless return from the International Space Station yesterday (Sept. 10) … a shot taken from space itself.
“Our view of the picture perfect reentry of TMA-12M,” wrote Expedition 41 astronaut Reid Wiseman, who just hours before bid farewell to Steve Swanson (NASA), Alexander Skvortsov (Roscosmos) and Oleg Artemyev (Roscosmos). The re-entry was in fact so perfect that TV cameras caught the parachute immediately after deployment, which doesn’t always happen.
As you can see in the video replay below, the Soyuz made a bulls-eye landing near Dzhezkazgan, Kazakhstan at 10:23 p.m. EDT (2:23 a.m. UTC). There are now only three people tending to the space station until the rest of the Expedition 41 crew launches, which is expected to happen Sept. 25.
An independent investigation committee is looking at why two European navigation satellites are in the wrong orbits following their launch from French Guiana last week.
While the first part of the launch went well, officials said telemetry from the satellites showed that the satellites were not where they were supposed to be. The probe is ongoing, but officials believe it is related to a stage of the Soyuz rocket that hefted the satellites into space.
“According to the initial analyses, an anomaly is thought to have occurred during the flight phase involving the Fregat upper stage, causing the satellites to be injected into a noncompliant orbit,” wrote launch provider Arianespace in an update on Saturday (Aug. 23).
The same day, the European Space Agency added that officials are looking into how the mission would be affected, if at all.
The Galileo satellites, the fifth and sixth of the constellation, are intended to serve as part of a cloud of navigation satellites that would be a European alternative to the United States GPS system. Officials are hoping to launch six to eight more satellites per year until 2017, when 24 satellites and six backups will be ready for full service.
The satellites were supposed to be in a circular orbit, inclined at 55 degrees to the Earth’s equator and have a maximum orbital radius (semi-major axis) of 29,900 km (18,579 miles). Telemetry now shows the satellites are in a non-circular orbit inclined at 49.8 degrees, with a semi-major axis of 26,200 km (16,280 miles).
Spectacular snapshots of the Southern Lights, Shooting Stars, the Sahara Desert and much more are streaming back from space to Earth courtesy of Alexander Gerst, ESA’s German astronaut currently serving aboard the International Space Station (ISS).
See a gallery of Alex’s stunning space-based views (sagenhafte Weltraum bilder) collected herein – starting with the auroral fireworks seen from space – above. It coincides with the Earth-based fireworks of America’s 4th of July Independence Day weekend celebrations and spectacular Noctilucent Clouds (NLCs) wafting over the Northern Hemisphere.

“Saw a beautiful Southern Light last night. I so wish you could see this with your own eyes!” Alex tweeted in English.
Gerst is posting his Earth & space imagery from the ISS on a variety of social media including Twitter, Facebook, Google+ and his ESA astronaut blog bilingually in English and German.
“Habe gestern ein wunderschönes Südlicht gesehen. Ich wünschte ihr könntet das mit eigenen Augen sehen!” Alex tweeted in German.

Gerst launched to the ISS on his rookie space flight on May 28, 2014 aboard a Russian Soyuz capsule along with Russian cosmonaut Maxim Suraev and NASA astronaut Reid Wiseman.
The trio are members of Expeditions 40 and 41 and joined three more station flyers already aboard – cosmonauts Alexander Skvortsov & Oleg Artemyev and astronaut Steve Swanson – to bring the station crew complement to six.
Alex will spend six months on the ISS for ESA’s Blue Dot mission. He is Germany’s third astronaut to visit the ISS. He is trained as a geophysicist and a volcanologist.
Gerst also has practiced and honed another talent – space barber! He shaved the heads of his two American crew mates – to match his bald head – after winning a friendly wager with them when Germany beat the US in a 2014 FIFA World Cup match on June 26.
Here’s several of Alexander Gerst’s newest views of the Sahara Desert and more.

Facing sanctions from the United States government, a high-ranking Russian official took to Twitter today (April 29) to express his frustration, warning that NASA has few options should Soyuz flights to the International Space Station cease.
“After analyzing the sanctions against our space industry, I suggest to the USA to bring their astronauts to the International Space Station using a trampoline,” wrote Dmitry Rogozin, Russia’s deputy prime minister, in a Russian-language tweet highlighted by NBC News.
The jibe points to the fact that only the Russians can bring crews up to the space station right now. Rogozin also linked to a story in Russian RT where he is quoted as saying (if Google Translate is correct) that the Americans will see a “boomerang” of sanctions laid upon Russian officials.
On April 2, as part of a larger policy of the Obama administration, NASA announced it would cease most connections with Russia except for those essential ones related to the International Space Station. NASA administrator Charles Bolden has repeatedly said that things are normal with the Russians when it comes to the station.
The United States is dependent on the Russian Soyuz to bring astronauts to the space station. The U.S. method of transportation ceased in 2011 after the space shuttle retired, and commercial spacecraft — though being developed — are not expected to be ready until about 2017.
That said, one of the developers of these spacecraft — SpaceX CEO Elon Musk — wrote on Twitter that the public will soon see the unveiling of the human-rated Dragon spacecraft that the company has been working on with contract money from NASA. (The other funded spacecraft proposals are Boeing’s CST-100 and Sierra Nevada’s Dream Chaser).
Sounds like this might be a good time to unveil the new Dragon Mk 2 spaceship that @SpaceX has been working on w @NASA. No trampoline needed — Elon Musk (@elonmusk) April 29, 2014
Cover drops on May 29. Actual flight design hardware of crew Dragon, not a mockup.

The Russian situation is expected to weigh heavily on NASA budget discussions for fiscal 2014 and 2015 as agency officials try to make their case that commercial funding should be sustained, or even increased, for Americans to be able to launch from their own soil again quickly.
Imagine clinging on to the side of a rocket, somehow able to hang on despite the high speeds and diminishing oxygen. Looking down, this is what you’ll see — the view in the video above. This incredible sequence shows Sentinel-1a during its initial climb to orbit last week and, if you wait long enough, you can even see the separation of the third stage.
“Arianespace’s successful Soyuz Flight VS07 — which deployed Sentinel-1A to Sun-synchronous orbit — gave the world a front-row seat in space,” the company stated on YouTube. “Cameras mounted on the Soyuz’ Fregat upper stage captured the spectacular footage … as Sentinel-1A was separated at approximately 700 km [434 miles] above the Earth to commence its life in orbit.”
Sentinel-1a is the first of a series of environmental monitoring satellites overseen by the European Space Agency, a set that promises views of the Earth in high-definition.

Update, 8:33 p.m. EDT: The Soyuz spacecraft arrived safely at station at 7:53 p.m. EDT (11:53 a.m. UTC) and coverage of the hatch opening is scheduled at 10:15 p.m. EDT (2:15 a.m. UTC).
After spending an extra couple of days in the cramped Russian Soyuz spacecraft, the incoming International Space Station crew will likely be very be glad to get out and stretch their legs. You can check out the festivities live in the video link above.
Three people are set to make a docking with the orbiting complex at 7:58 p.m. EDT (11:58 p.m. UTC). If all goes to schedule, they’ll pop the hatch open at 10:40 p.m. EDT (2:40 a.m. UTC). Meanwhile, engineers are trying to figure out what caused the malfunction that prevented a docking as planned on Tuesday (March 25).
Remember that all schedules are subject to change, so tune into NASA TV well before each event happens.
The Expedition 39/40 crew lifted off Tuesday afternoon (EDT) from Kazakhstan to take a fast track to the space station that should have seen them dock on launch day. The Soyuz has to make three engine firings or burns to accomplish this. The docking was cancelled after the third burn did not happen as planned. The Russian Federal Space Agency (Roscosmos) has determined this was because the spacecraft was in the wrong orientation, but the underlying cause is still being investigated.
Once this happened, the crew switched to a standard backup procedure to bring them to the station in two days instead. (This path, in fact, was what all crews did up until last year.) The crew is safe and in good spirits heading up to the docking, NASA has said. The Soyuz has done several other engine firings since, with no incident.
The Soyuz crew includes Steve Swanson (NASA), Alexander Skvortsov (Roscosmos) and Oleg Artemyev (Roscosmos). Awaiting them on the station are Koichi Wakata (Japan Aerospace Exploration Agency), Rick Mastracchio (NASA) and Mikhail Tyurin (Roscosmos). Wakata is in command of the station, marking a first for Japan’s astronaut corps.
Despite a problem that held up last night’s International Space Station docking, the Expedition 39/40 crew is doing well as they execute a standard backup procedure to bring their Soyuz spacecraft to the station on Thursday, NASA said.
The crew was originally expected to dock with the station around 11 p.m. EDT (3 a.m. UTC), but an error with the spacecraft’s position in space prevented the engines from doing a third planned “burn” or firing to make that possible, NASA said in an update.
“At this point, the crew is in good shape and the vehicle appears to be in good shape,” said Kenny Todd, the space station’s operations integration manager, in an interview on NASA TV Wednesday morning (EDT). “At this point, everything looks real good.”
In fact, the spacecraft has done a couple of burns since to get it into the right spot for a docking Thursday evening, Todd added. (So it appears the crew just missed the window to get there on Tuesday night.) The underlying cause of the orientation problem was not mentioned in the interview, presumably because it’s still being investigated.
NASA is quite familiar with a two-day route to the space station as up until last year, all crews took two days to get to the space station. This took place for 14 years until a rapider method of reaching the orbiting complex within hours was introduced.
The crew includes Steve Swanson (NASA), Alexander Skvortsov (Roscosmos) and Oleg Artemyev (Roscosmos), who will join three people already on station when they arrive.
Current station residents Koichi Wakata (the commander, of the Japan Aerospace Exploration Agency), Rick Mastracchio (NASA) and Mikhail Tyurin (Roscosmos) got to sleep in this morning and had some minor modifications to their schedule because of the docking delay, Todd added.
Instead of taking the day off as planned, the crew will do some work. A planned ISS software update for last night is going to be pushed “down the line”, Todd said, adding that the forthcoming SpaceX launch on Sunday and docking on Tuesday is still going ahead as planned.
We’ll provide more updates as the situation progresses. Docking is scheduled for 7:58 p.m. EDT (11:58 p.m. UTC) Thursday and will be covered on NASA Television.
What you see above is 32 minutes of something going wrong during each launch. While humanity has been launching things into space since the 1950s, you can see just how hard it is — over and over again. And when humans are riding aboard the rockets, the toll becomes more tragic.
According to the YouTube author of the video above, the vehicles shown include “V2, Vanguard TV3, Explorer S-1, Redstone 1, Titan I, Titan II, Titan IV, Atlas, Atlas-Centaur, N1, Delta, Delta III, Foton, Soyuz, Long March, Zenith, Space Shuttle Challenger, and more.”
Naturally, with each failure the engineers examine the systems and work to fix things for next time. A famous example is the Challenger shuttle explosion, which you can see about halfway through the video. There were multiple causes for the failure (human and technical), but one of them was an O-ring that failed in cold weather before the launch. NASA revised the launch rules and with contractors, made some changes to the booster rocket design, as a 2010 Air and Space Smithsonian article points out:
Freezing temperatures weakened an O-ring seal in a joint between two segments of the right booster. The weakness allowed hot gases to burn through the casing, causing the shuttle to break apart on ascent, which killed the seven-member crew. Two joints were redesigned with interlocking walls that had new bolts, pins, sensors, seals, and a third O-ring.
Still, launching is a risky business. That’s why it’s so important that engineers try to catch problems before they happen, and that as soon as a problem is seen, it’s fixed.
