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.

A breathtaking view of the Apollo 15 landing site
The Lunar Reconnaissance Orbiter team has released a wide angle side view image of the Apollo 15 landing site, showing the lunar module and the areas around Hadley Rille and the Apennine Mountain range that the astronauts explored using their lunar jeep. 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.

Vintage leather football helmets are often as protective as modern hard football helmets
Newer is not always better: A study has found that vintage leather football helmets used in the early 1900s can be as good if not better than modern hard football helmets in protecting the head.

Robot obstacle course
An evening pause: The robot obstacle course at the 2006 ROBO-ONE competition in Kawasaki, Japan. Very impressive, for a machine, though this does illustrate how difficult it is to artificially duplicate what life does so naturally.
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.

Two hacker attacks of American climate satellites in the past four years
A congressional report today revealed that two American climate satellites were attacked by hackers in the past four years.
In October 2007 and July 2008, a NASA-managed Landsat-7 satellite experienced 12 or more minutes of interference, and a Terra AM-1 satellite was disrupted for two minutes in June 2008 and again that October for nine minutes, according to Bloomberg Businessweek’s analysis of the annual report by the U.S.-China Economic and Security Review Commission. The report says the hackers gained access to the satellites — both are used for Earth climate and terrain monitoring — through the Svalbard Satellite Station in Spitsbergen, Norway. It’s believed the attackers may have hijacked the Internet connection at the Norway ground station to interfere with the operation of the satellites.

Dismantling the last U.S. hydrogen bomb
Dismantling the last American hydrogen bomb.
The [9 megaton] B53 was designed in the 1950s and replaced 500 B41s, which had a yield of 25 megatons. The largest nuclear device ever built and tested was the 27 ton Russian AN602, which had a yield of 50 megatons. It was eight meters (26 feet) long and 2.1 meters (6.9 feet) in diameter. Only one of these was built. The Russians followed the Americans in phasing out large yield bombs in favor of smaller, and more numerous ones. This was largely the result of ICBM warheads designed to carry multiple nuclear weapons.
