Phobos-Grunt is now expected to fall to Earth sometime around January 16
It’s official: Phobos-Grunt is now expected to fall to Earth sometime around January 16.
Meanwhile, the head of the Russian space agency is looking for a scapegoat for his country’s recent space failures.
Roskosmos chief Vladimir Popovkin told the Izvestia daily he could not understand why several launches went awry at precisely the moment the spacecraft were travelling through areas invisible to Russian radar. “It is unclear why our setbacks often occur when the vessels are travelling through what for Russia is the ‘dark’ side of the Earth — in areas where we do not see the craft and do not receive its telemetry readings,” he said. “I do not want to blame anyone, but today there are some very powerful countermeasures that can be used against spacecraft whose use we cannot exclude,” Popovkin told the daily.
With leadership like this, Russia might soon join the U.S. as a country unable to get astronauts into space.

After 16 years in space, NASA’s Rossi X-ray Timing Explorer (RXTE) has been shut down
After 16 years in space, NASA’s Rossi X-ray Timing Explorer (RXTE) has finally been shut down.
RXTE far exceeded its original science goals and leaves astronomers with a scientific bounty for years to come. Data from the mission have resulted in more than 2,200 papers in refereed journals, 92 doctoral theses, and more than 1,000 rapid notifications alerting astronomers around the globe to new astronomical activity.
“The spacecraft and its instruments had been showing their age, and in the end RXTE had accomplished everything we put it up there to do, and much more,” said Tod Strohmayer, RXTE project scientist at Goddard. The decision to decommission RXTE followed the recommendations of a 2010 review board tasked to evaluate and rank each of NASA’s operating astrophysics missions.

The article focuses on how this could save us from global warming. What I see is a possible tool for making the construction of interplanetary spaceships more practical. On any vessel in space, something has to cleanse the air of carbon dioxide. Finding a cheap way to do this makes building those vessels much easier.

A fitting memorial
Opportunity has settled into its winter haven.
NASA’s Mars Exploration Rover Opportunity will spend the next few months during the coldest part of Martian winter at Greeley Haven, an outcrop of rock on Mars recently named informally to honor Ronald Greeley, Arizona State University Regents’ professor of planetary geology, who died October 27, 2011.
I met and interviewed Greeley a number of times in writing articles for magazines like Sky & Telescope and Astronomy. For years he was a central figure in the field of planetary geology, and his life effort is one of the prime reasons the United States has dominated this field for most of the past half century, with a fleet of planetary missions presently at Mercury, Mars, Jupiter, Saturn, and Pluto, with many more to come.
The article notes that the International Astronomical Union (IAU) has the job of naming objects in space, and could take years to honor Greeley. I say that if these scientists, the true explorers of Mars, want to name something for him, then they should go ahead, and future generations should honor that choice, regardless of what the IAU says.
ArianeSpace will make a profit in 2011, the first time in three years
ArianeSpace will make a profit in 2011, the first time in three years.
Helped by the two Soyuz campaigns, which occurred in October and December, Arianespace in 2011 apparently averted a third consecutive year of losses. Its financial accounts are not finalized until June, but Le Gall said the company expects to report a slight profit on about 985 million euros in revenue.
In other words, it was the addition of the Russian low-cost Soyuz rocket to their fleet that helped avoid another year’s loss. This doesn’t reflect well on the profitability of the Ariane 5 rocket.

China issues a white paper on space, outlining its future goals
China today issued a white paper on space, outlining its future goals. In addition to additional launches of its manned Shenzhou manned capsule,
China also plans to launch space laboratories, manned spaceship and space freighters, and will start a research on the preliminary plan for a human landing on the moon, the document said.
As an important part of deep-space exploration, the country’s lunar probe projects follow the idea of “three steps” — orbiting, landing and returning. In next five years, the country plans to launch orbiters for lunar soft landing, roving and surveying to implement the second stage of lunar exploration, then it will start the third-stage project of sampling the moon’s surface matters and get those samples back to Earth, the white paper said.

Good news: A Russian Soyuz-2 rocket successfully launched six satellites into orbit today, less than a week after a differently configured Soyuz-2 rocket had failed.

China has activated its own GPS satellite system.
China had so far launched 10 satellites for the Beidou system, including one this month, and planned to put six more in orbit in 2012 to enhance the system’s accuracy and expand its service to cover most of the Asia Pacific region.

A family struggles to complete a Knoxville to Nashville trip using an electric car
An exercise in absurdity: A family struggles to complete the 180 mile trip from Knoxville to Nashville using an electric car.
The Blink fast-charge station was on the blink. Efforts to use the two available plugs yielded nothing for Stephen Smith when he and his family arrived in Lebanon in their electric vehicle.
But all was not lost as the Smiths closed in on their destination – a brother’s house only 22 miles away in Antioch. With ten miles of available power left on their car, they could take advantage of a slower charger next to the other at the Blink station at Cracker Barrel. It took about an hour, but the boost gave enough energy for a total of 30 miles.
They also had to pay attention to whether the route was flat or hilly, as any hills significantly reduced their range of about 75 miles. In addition, they found that even that number was unreliable, and that often the maximum range the car could travel was far less.
Even the fast-charge station still needed about 30 minutes to charge up the car. Imagine having to wait 30 minutes every time you needed to fill up, and imagine having to do it every 70 miles.
There is a reason electric cars can’t compete with gasoline, and this journey illustrates it.

After the launch failure on Saturday of a Soyuz rocket, I suspect that top management got gun shy about doing another launch so soon thereafter.

The NASA shuttle simulator for training astronauts is going to at Texas A&M
The NASA shuttle simulator for training astronauts is going to Texas A&M.
Valasek said it won’t be a static display for viewing but a functional flight simulator. Visitors will be able to sit in the seats and cockpit and manually fly a simulated re-entry as the shuttle astronauts did. “When operational again, the SMS will be the centerpiece of many educational, outreach, and research activities for a long time to come,” Valasek said. “And it will be accessible. Until now, 355 astronauts have trained on the Shuttle Motion Simulator and flown on a space shuttle mission. Now the rest of us can experience at least a part of the excitement of space exploration, just the way the astronauts trained for it.”
The simulator will be used in aerospace engineering courses and accessible to all Texas A&M students, staff, and faculty. Spaceflight enthusiasts and fans of technology, whether affiliated with the university or not, will also be able to enjoy it.
Now, this is what an engineering school should be focused on, rather than the skin color of its students.
