During a five hour EVA that had lots of difficulties, two Russian cosmonauts took the Olympic torch on a spacewalk
During a five hour EVA yesterday that had lots of minor technical difficulties, two Russian cosmonauts took the Olympic torch on a spacewalk.
Most of the press is focusing on the PR stunt with the Olympic torch, but I think these issues are more interesting:
Working around the Service Module, Kotov and Ryazanski worked on cables at the RK21 site before attempting to fold up the panels on the hardware into its original configuration. The EVA tasks were mainly related to the preparations on the Urthecast pointing platform for installation of the HD camera in December. However, only the removal of the launch restraint from VRM EVA workstation and the disconnection of the RK-21 experiment were completed. The duo struggled with the relocation of the Yakor foot restraint – which they opted to take back to the airlock instead – while also failing to fold and lock RK-21 experiment antenna panels. While the spacewalkers managed to take a large quantity of photos for engineers on the ground to examine, the spacewalk was concluded after the failure to fold up the RK-21 panels, resulting in outstanding tasks for the next EVA.
ESA has issued an update on when and where they think GOCE will impact the Earth.
Chicken Little report: ESA has issued an update on when and where they think GOCE will impact the Earth.
You can see the ground tracks of the orbits here. It looks like the thing does have a chance of coming down over the U.S., should it come down in the early part of the prediction.
Engineers now expect the European GOCE research satellite to crash to Earth either late Sunday or on Monday.

Some pieces are going to reach the Earth’s surface, so be prepared to duck. You can see the predicted orbital path here.
Virgin Galactic has signed a deal with NBC to televise the first commercial flight of SpaceShipTwo.
Virgin Galactic has signed a deal with NBC to televise the first commercial flight of SpaceShipTwo.
I note that with this announcement Virgin Galactic has backed off from its previous schedule for launching this flight this year. They now say it will happen in 2014.
Unlike an earlier test where one fairing did not release, a second test of Orion’s shroud separation system was successful this week.

Video below the fold. The gun clearly functions, though I noticed that in the video they never loaded more three rounds in a magazine, and that the gun seems to cycle weakly. I suspect that they had some feeding problems when they tried to fire a full loaded five round magazine.
Nonetheless, this achievement further illustrates that 3D printing is about to become a major method of manufacture.

A rare new microbe has been found in two different clean rooms, one in Florida and the other in South America.
A rare new microbe has been found in two different clean rooms, one in Florida and the other in South America.
This population of berry-shaped bacteria is so different from any other known bacteria, it has been classified as not only a new species, but also a new genus, the next level of classifying the diversity of life. Its discoverers named it Tersicoccus phoenicis. Tersi is from Latin for clean, like the room. Coccus, from Greek for berry, describes the bacterium’s shape. The phoenicis part is for NASA’s Phoenix Mars Lander, the spacecraft being prepared for launch in 2007 when the bacterium was first collected by test-swabbing the floor in the Florida clean room.
Some other microbes have been discovered in a spacecraft clean room and found nowhere else, but none previously had been found in two different clean rooms and nowhere else. Home grounds of the new one are about 2,500 miles (4,000 kilometers) apart, in a NASA facility at Kennedy Space Center and a European Space Agency facility in Kourou, French Guiana.
Unlike the bacteria found on ISS, this microbe does not appear to pose any specific health problem. It does provide biologists with a good example of the kind of life that might survive in hostile environments like Mars.
Students crash rockets into the ground on purpose! With video.
Students crash rockets into the ground on purpose! With video.
In what at first glance seems like a terrible sense of direction, in March students from the University of Washington fired rockets from kites and balloons at an altitude of 3,000 ft (914 m) straight into the ground at Black Rock, Nevada: a dry lake bed in the desert 100 mi (160 km) north of Reno. This may seem like the ultimate in larking about, but it’s actually a serious effort to develop new ways of collecting samples from asteroids.
At the same time announcing that a third powered test flight of SpaceShipTwo will occur in about a month, Virgin Galactic has now admitted that commercial flights will not occur in 2013.
