Russian space agency head says there is still a chance to save Phobos-Grunt
The head of the Russian space agency said yesterday that there is still a chance to save Phobos-Grunt.
“The probe is going to be in orbit until January, but in the first days of December the window will close” to re-programme it, he told Russian news agencies at Russia’s Baikonur cosmodrome in Kazakhstan.
He also said that the probe will not pose a threat, and will burn up in the atmosphere if it should fall to Earth.

Scheduling the next Dragon flight, the first to dock with ISS
Scheduling the next Dragon flight, the first to hopefully berth with ISS.
Presently they are saying early January, though it appears that no one will be surprised if it gets delayed to February.

Soyuz rocket successfully launches three astronauts into orbit
A Soyuz rocket has successfully launched three astronauts into orbit.
This is the first manned launch since the shuttles were retired, and the first Russian manned mission since the failure of a Soyuz rocket in August. If all goes well, the astronauts will dock with ISS in two days.

NASA halting work on its J-2X rocket engine
Par for the course: NASA, having successfully completed a 500 second test of the J-2X rocket engine, has halted all further development work on that engine.
The NASA program to build the heavy-lift rocket is expected to get $1.2 billion per year, and yet it doesn’t have enough money to develop both its first and second stages simultaneously? Kind of proves my point that NASA’s fixed labor costs, imposed on it by Congress, makes it impossible for the agency to ever build anything at a competitive price.
The result: every project dies stillborn.

Toxic Russian Mars probe aims for Earth
It now looks like the stranded and toxic Russian Mars probe, Phobos-Grunt, is likely aimed at Earth.
We are looking at an uncontrolled toxic reentry scenario. Phobos-Grunt . . . is fully-laden with unsymmetrical dimethylhydrazine and nitrogen tetroxide; that’s ten tons of fuel and oxidizer. The probe itself weighs-in at only three tons. . . . Phobos-Grunt’s batteries are draining and its orbit is degrading. It looks as if the probe will reenter later this month/early December. NORAD is putting a Nov. 26 reentry date on Phobos-Grunt.

“Overnight, several attempts were made to obtain telemetric information from the probe. They all ended with zero result,” Interfax quoted a source in the Russian space sector as saying. “The probability of saving the probe is very, very small,” added the source, who was not identified.

NASA picks the Delta 4 Heavy to launch Orion into orbit on its first test flight
NASA has chosen the Delta 4 Heavy rocket to launch the Orion capsule into orbit for its first test flight in 2014.
So, tell me again why NASA needs to spend $18 to $62 billion for a new rocket, when it already can hire Lockheed Martin to do the same thing? Though the Delta 4 Heavy can only get about 28 tons into low Earth orbit, and only about 10 tons into geosynchronous orbit — far less than the planned heavy-lift Space Launch System rocket — Boeing Lockheed has a variety of proposed upgrades to Delta 4 Heavy that could bring these numbers way up. Building these upgrades would surely be far cheaper than starting from scratch to build SLS.

Phobos-Grunt appears to be in trouble in Earth orbit
Phobos-Grunt appears to be in trouble in Earth orbit.
In a posting to an online forum for the Phobos-Grunt mission, Anton Ledkov of the Russian Space Research Institute reported that there was “no telemetry” from the spacecraft.
Another report suggests that a variety of engine thrusters did not fire as planned.

NASA moves first flight test of Orion capsule up three years to 2014
NASA has moved the scheduled first flight test of the Orion capsule up three years to 2014.
This action, while good, was almost certainly triggered by the competition from the private space companies. The managers at NASA are finally realizing that if they don’t speed up deployment of their own spacecraft, they will certainly lose in the competition for government dollars. That they will have to use another rocket other than their heavy-lift vehicle for this launch, however, will not help that particular project’s lobbying effort.
Either way, I think this action is only further proof that the more competition we have, the quicker we will get into space. And the journey will cost less too, not only because it will take less time and therefore less money, but the competition between companies (or NASA) will force everyone — including NASA — to lower costs to show they can do it better.

DARPA has launched a program to use airplanes as the launchpad for putting satellites in orbit
DARPA has launched a program to use airplanes as a launchpad for putting satellites in orbit.
The Pentagon’s research agency, the Defense Advanced Research Projects Agency (DARPA), also anticipates slashing small satellite payload costs from more than $30,000 per pound to less than $10,000 per pound — making such launches three times cheaper. . . . DARPA wants the program to demonstrate at least 12 launches of 100-pound payloads to low Earth orbit, with each launch costing about $1 million. Launches could start as soon as 2015, according to DARPA’s official announcement of the program on Nov. 4.
At first glance this appears to be good news for Orbital Sciences and its Pegasus rocket, the only commercial launch system that has successfully put satellites into orbit using a commercial L1011 airplane as its first stage. At the same time, however, it appears DARPA is pushing for new technology to lower costs below what Orbital charges, meaning the game is open to anyone.

Below is a cropped close-up, showing the landing site near the top of the image with Hadley Rille near the bottom. Below the fold is a second image showing a wider view that includes the Apennine mountain slope that the astronauts drove their rover up.

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.

Russia heads for Mars
Russia heads for Mars: a detailed look at the Phobos/Grunt sample return mission, set to launch on November 8.
I really wish the Russians good luck with this project. Not only would it herald their return to planetary science since the fall of the Soviet Union, success here would break their long string of failures to the red planet. Though their unmanned planetary program had some remarkable achievements during the Soviet era, of the 19 missions they flew to Mars in the 1960s, 1970s, and 1980s, all were failures, producing almost no useful data.

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.
