VERY INTERESTING! Koronas-Foton may be used for EARTHQUAKE FORECASTS!

Google translate - don't have time to check for accuracy - following a shuttle misison.

Special thanks to a friend of mine on my own board!

recently, STEP began to observe streams of fast electrons emitted from the Earth's surface and in the absence of solar activity, and just where in theory they should not - at low latitudes.

Mildly interesting, but there've been many stories over the years about amazing breakthrough discoveries in earthquake prediction.

This is what I'm going to ask - is this serious or it's a topic brought out by the woewoes?

Well, if it isn't repeatable, it isn't science.
Let's see if they can reproduce these results. Better yet, let's see if they can issue an earthquake warning before a quake.

The instrument TESIS aboard Koronas-Foton photographed a huge solar flare. This is a spectacular image.

That is a great image, and a little way into the story there is a link to a 20 second movie from where that image originates.

(good catch Zvezdichko! and thanks)

Oh, wow...first Stu's great HiRISE colorization, now this!!! That's a really stunning image!

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

TESIS observes active field 1029. This is how the field formed:

BAD NEWS - Koronas-Foton is in Safe mode due to a problem with power supply

http://lenta.ru/news/2009/12/11/tesis/

GOOGLE TRANSLATE:

http://translate.google.com/translate?hl=e...2F11%2Ftesis%2F

I also have information that engineers are trying to restore power supply and turn on the scientific instruments, but these attempts aren't successful.

Yesterday I googled the Russian Google and came across this article:

http://www.rian.ru/science/20091211/198635487.html

They say there is hope, but all attempts to restore the spacecraft have been unsuccessful. The situation is very serious and the outcome isn't clear. Degradation started gradually.

Yes, it is. It's not a typical safe mode, but we have a known technical issue standing behind it, which is quite serious.

I remind you that the expected lifespan of the spacecraft was supposed to be about 3 years.

There's an interesting discussing going at novosti-kosmonavtiki.ru forum. As we already know: We have faulty chemical batteries, but the scientific instruments and the other components are healthy. Standart questions are being asked: Who is the contractor responsible for the batteries? Why did they allow the satellite to fly with such faulty batteries? Who is to blame? After all, a reader says, SOHO was launched in 1996 and still works, it's the same situation with STEREO and HINODE.

There is a possibility, another reader says, that the batteries are OK, but a sensor has faltered.

Another reader offers that a system should be built so we could collect faulty satellites and return them to the Earth smile.gif Why not on-orbit repair, I should ask tongue.gif

Very, very interesting forum, too bad my spoken Russian isn't fluent sad.gif

Russia loses contact with Koronas-Foton


http://tesis.lebedev.ru/status.html

Russia has announced that Koronas-Foton no longer communicates with Earth since 11th December.

Engineers will try to communicate with the satellite on Monday because the solar batteries will be well lit then.

http://www.sat-nd.com/

Koronas-Foton silent after problems with power supply
13 Dec 2009 - The scientific payload aboard Russia's solar research satellite Koronas-Foton was switched off owing to power supply problems on 1 December, Novosti news agency reported. Contact with the spacecraft was subsequently lost, and chances of a recovery are said to be slim

This is terrible to hear.
Of curiosity, does Koronas-Foton have anything in common with Fobos-Grunt? Any similar systems that could need to be checked as a result of this?
