Phobos-Grunt due to crash to Earth anytime in the next ten hours

path of Phobos-Grunt's reentry

Updated and bumped. An updated prediction from Aerospace now calls for Phobos-Grunt to come down sometime between 9 and 3 pm (Eastern). This puts the U.S. now out of danger, though Europe, South America, Africa, Australia, and the southern half of Asia all remain in the spacecraft’s path.

Watch your heads! Phobos-Grunt is due to crash to Earth anytime in the next ten hours. And unfortunately, this new prediction has it flying over both North America and much of Europe and Africa during that time period.

Phobos-Grunt’s reentry this weekend

path of Phobos-Grunt's reentry

Watch your head this weekend: The re-entry of Phobos-Grunt has been refined, and is expected to come down sometime between 5 pm (Eastern), Saturday January 14 and 9 am (Eastern), Monday January 16.

As you can see by the image on the right, there is as yet no way to predict where it will land, though it appears that — except for the tip of Florida — North America is in the clear. The blue lines show its orbital path during the first half of this window, while the yellow lines show its path during the window’s second half.

Phobos-Grunt is now expected to fall to Earth sometime around January 16

9:29 am

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.

A Russian scientist has found large amounts of methane being released in the atmosphere in the Arctic

5:43 pm

A Russian scientist has found large amounts of methane being released into the atmosphere in the Arctic, far more than previously predicted.

It is speculated that these releases are the result of the Earth’s warming climate during the past several hundred years. And because methane is a far more powerful greenhouse gas than carbon dioxide, its release will feed into that warming.

Phobos-Grunt: what’s in a name?

9:19 am

Some English commentary from Russia: Phobos-Grunt: what’s in a name?

And this is the part when I point out that Russia’s unmanned Mars missions, which have not been successful so far, have a name problem that goes beyond Phobos-Grunt.

Mars-94? M1 No. 520? Seriously? What is this dour nonsense? Soyuz-Fregat was an improvement, but still, considering the consistent failure rate of the Mars missions, it’s time to get serious about breaking that curse. Take a page out of the Americans’ book, just this once, and inject some optimism into your space program. The Americans give their *successful* spacecraft names like Phoenix! And Spirit! And Opportunity! So name your spacecraft a variation on the word Hope! Throw caution to the wind and name it Kickass! Certainly don’t name it after terror, even if the satellite you plan on exploring is already stuck with that unfortunate name.

An update on the efforts to save Phobos-Grunt

An update on the efforts to save Phobos-Grunt.

“The first pass was successful in that the spacecraft’s radio downlink was commanded to switch on and telemetry was received,” said Wolfgang Hell, ESA’s Service Manager for Phobos–Grunt. Telemetry typically includes information on the status and health of a spacecraft’s systems. “The signals received from Phobos–Grunt were much stronger than those initially received on 22 November, in part due to having better knowledge of the spacecraft’s orbital position.”

The second pass was short, and so was used only to uplink commands – no receipt of signal was expected. However, the following three passes in the early morning of 24 November proved to be more difficult: no signal was received from Phobos–Grunt.
