Russians launch Mars moon {Phobos} probe (BBC) {and Chinese Mars orbiter}
By Jonathan Amos
Science correspondent, BBC News

Russia has launched an audacious bid to scoop up rock and dust samples from the Martian moon Phobos and bring them back to Earth for study.

The dusty debris should provide fresh insights into the origin of the 27km-wide moon that many scientists suspect may actually be a captured asteroid.

The mission is called Phobos-Grunt - "grunt" means "soil" in Russian.

It is a significant venture also because it is carrying China's first Mars satellite.

Yinghuo-1 is a 115kg probe that will ride piggyback and be released into an observation orbit around the Red Planet.

1. Regarding translations and transliteration: Phobos = god of fear, Grunt = upper ground = topsoil

Regarding translations and transliteration.

Fortunately, in Polish we don't have such a problem because of common language group for Polish (West Slavian) and Russian (East Slavian).

In both of them the correct name for Greek god of fear is Fobos (F equals letter and sound like Greek Φ, and ф in Russian!). We also both use noun "grunt" to describe a top/upper layer of soil or ground or contact area between building and ground.

Thanks to all contributors of this topic, by the way.

2. Phobos-Grunt Mars probe loses its way just after launch
The Phobos-Grunt probe launched successfully but then failed
to fire the engine to put it on the correct path to the Red Planet.

Russian space agency officials say the craft is currently stuck in
an Earth orbit and that engineers have three days to correct the
fault before the probe's batteries run out.

The project is Russia's most ambitious space venture in recent years.

It has been designed to collect rock and dust samples from Mars'
moon Phobos and bring them back for study in labs on Earth.

3. Looks like they're going to maintain a perfect record ...
of failed Mars missions.

4. Some updates
http://www.russianspaceweb.com/phobos_grunt_launch.html

<snip>

On November 9, at 01:17 Moscow Time, a project representative reported that telemetry from the spacecraft had been received, confirming that onboard batteries had been recharging and the spacecraft had been oriented toward the Sun. Russian military tracking assets and NASA ground facilities were reportedly involved in the effort to track the mission.

<snip>

Although the spacecraft was expected to remain in orbit for at least 10 days before reentering the Earth atmosphere, in just two days it would descent too low for the available propellant to raise its parking orbit and conduct another attempt to enter escape trajectory toward Mars, reports said. However, RIA Novosti quoted an unnamed space official as saying that the spacecraft could "safely" remain in orbit from one week to up to a month. However whether the mission would be safe to resume during this entire period was not specified.

<snip>

November 10 developments

In early hours Moscow Time, the editor of this web site received a message from the director of Moscow-based Space Research Institute, IKI, Lev Zeleny, informing that tracking facilities of the US military provided significant help in establishing exact orbital parameters of the Phobos-Grunt spacecraft. This data was to be used during the previous night to send commands to the spacecraft as it was passing within range of ground control stations. Zeleny reassured that the mission team still had had "few days for reprogramming before the end of the Mars accessibility window for 2011."

6. I hope not
I like this kind of scientific exploration.

8. The Great Galactic Ghoul has struck again!
The Great Galactic Ghoul is a legend of the spaceways; a monster that hangs out between Earth and Mars and devours spacecraft (24 to date, not counting the probably doomed Phobos-Grunt). It's eaten more Russian spacecraft than American; apparently it likes the taste of Russian space probes better.

Actually, it's a long-standing in-joke with NASA. Space probes have to work in a very inhospitable environment, so it's no surprise that many of them fail. Actually, our average for successes is getting better.

Is this the Great Galactic Ghoul?


Actually, the image is from a NASA Halloween card based on a Spitzer telescope image.;-)
