The first in orbit tests of Robonaut halted because the robot did not carry out its commands as expected.

HAL lives! The first in-orbit tests of Robonaut were halted today on ISS because the robot did not carry out its commands as expected.

NASA robot operator Phil Strawser said joint movements in the weightless space environment have proven to be different than those performed in normal gravity on Earth. Consequently, software used to operate the robot needs to be “fine-tuned,” he said.

A new study has been released detailing the vision problems experienced by astronauts on space flights longer than six months

A new study has been released detailing the vision problems experienced by astronauts on space flights longer than six months. Hat tip to Clark Lindsey.

The visual system changes discovered by the researchers may represent a set of adaptations to microgravity. The degree and type of response appear to vary among astronauts. Researchers hope to discover whether some astronauts are less affected by microgravity and therefore better-suited for extended space flight, such as a three-year round trip to Mars.

In their report, Drs. Mader and Lee also noted a recent NASA survey of 300 astronauts that found that correctible problems with both near and distance vision were reported by about 23 percent of astronauts on brief missions and by 48 percent of those on extended missions. The survey confirmed that for some astronauts, these vision changes continue for months or years after return to Earth.

Sailing to Mars

With the end of the Mar500 simulated mission this coming Friday, the Russians are now proposing an eighteen month simulated Mars mission on board the International Space Station.

The Russians have been pushing to do this on ISS for years. Unfortunately, NASA has always resisted.

Yet, as I wrote in Leaving Earth, we will never be able to send humans to any other planets until we have flown at least one simulated mission, in zero gravity in Earth orbit, beforehand. Wernher von Braun pointed out this reality out back in the 1950s, and that reality has not changed in the ensuing half century. Not only will such a mission tell us a great deal about the medical issues of living in weightlessness for years at a time — issues that are far from trivial — it will give us the opportunity to find out the engineering problems of building a vessel capable of keeping humans alive during interplanetary flight, far from Earth.

Orbital announces revised schedule for its initial Taurus 2 and Cygnus flights

Orbital Sciences has announced its revised schedule for the initial Taurus 2 and Cygnus flights.

Orbital will conduct a test of the Taurus 2’s first stage on the launch pad in late January [2012], and the inaugural Taurus 2 flight in late February or early March. This will be followed, in early May, by a Taurus 2 flight carrying the Cygnus station cargo vehicle, a flight during which Cygnus is expected to demonstrate its ability to berth with the station. The first operational space station cargo-delivery mission for Taurus 2 and Cygnus will occur in late August or early September under this revised schedule, Orbital officials said.

Based on conversations I’ve had with people at Orbital, this delay was expected, and is a good thing. The company was under incredible time pressure to get ready for a December launch. Given that this will be the first test flight of Taurus 2, and it must work for the Cygnus cargo flights to follow, better they give themselves some working room to get it right.

Space News suggests Congress use the billions for NASA’s heavy-lift rocket to fund JWST

In an editorial yesterday Space News suggested that Congress use the billions it is allocating for NASA’s heavy-lift rocket to fund the James Webb Space Telescope instead.

This is not surprising. Webb already has a strong constiuency (astronomers, the public) while the Space Launch System has little support outside of Congress and the specific aerospace contractors who want the work. With tight budgets as far as the eye can see into the future, and the likelihood that Congress is going to become more fiscal conservative after the next election, it would not shock me in the slightest if SLS gets eliminated and the money is given to Webb. And if the SpaceX and Orbital Sciences cargo missions to ISS go well then cutting SLS would almost be a certainty, as this success would demonstrate that these private companies should be able to replace SLS for a tenth of the cost.

And I also think this would be a much wiser use of the taxpayers money.

Sierra Nevada’s Dream Chaser to get its first test flight in the summer of 2012

Dream Chaser, Sierra Nevada’s space plane, is to get its first test flight this coming summer.

For the unmanned test flight, it will be carried into the skies by WhiteKnightTwo, the carrier aircraft for the commercial suborbital passenger ship SpaceShipTwo, backed by Virgin Galactic, a U.S. company owned by Richard Branson’s London-based Virgin Group.

Orbital Sciences has launch success

Orbital Sciences has a launch success, putting an Air Force reconnaissance satellite into orbit from the Kodiak Launch Complex in Alaska.

For Orbital, this success cleans off some of the stain left on the company from the recent launch failures of its Taurus 1 rocket. What would leave the company stainless, however, will be a successful first launch of its new Taurus 2 rocket, needed to carry its Cygnus capsule to ISS and scheduled for late this year.
