http://www.newsinfo.ru/news/2008-12-15/sputnik/174938

Russia will launch a new spacecraft to study the Sun - Koronas-Foton (or Coronas-Photon). Launch is scheduled to occur on 29th of jan 2009.

This is supposed to be the last launch of a Tsyklon rocket.

Once launched Koronas-Photon will be placed into a cirtular orbit 500kms above the Earth. Orbital inclination - 82.5 deg.

I don't see the reference to the Tsyklon launcher in the Google translation. Was that mentioned in a separate reference?

Thanks.

Yes, it was - there was a Roscosmos link, but the website is currently closed due to technical problems.

Roscosmos plans to launch today. Russian scientists thing big again - they say the "highest priority" of the mission is to answer the question how to avoid Solar radiation during trips to Mars.


EDIT : Launch postponed for a day.

http://www.tesis.lebedev.ru/project_diary.html

They confirm that the first and the second stages of the rocket have worked. We don't have confirmation that the third stage has worked. The first radiosignal of the spacecraft should be received at 18:02 Moscow time. This means yet another 40 minutes of tense waiting.

So far, telescopes alone spent more than a day: in total during this period received approximately 200 images. The images are not yet centered: the frame of the Sun shows the actual situation in the field of detectors. At tomorrow scheduled a series of moves mirror telescopes, in which images the Sun will be transferred to the working area detectors.

OK, I will try to help you (Russian is close to Bulgarian and I almost have no problems):

http://www.tesis.lebedev.ru/info/tesis_20090723.php

According to this publication the culmination of the Solar Eclipse occurred together with the strongest magnetic storm in the past 7 months.

http://www.tesis.lebedev.ru/upload/files/kp_20090722.png

The green color on the chart means normal magnetosphere, orange - excited magnetosphere, red color - magnetic storm.

G1 is a very weak storm G2 - average storm, G3 - strong storm G4 - very strong storm G5 - extreme storm.

So according to the chart the storm during the Solar eclipse is close to G2 = average storm.

I'm also able to read: The storm was unexpected. The Sun is very calm now and there are no spots on the surface. In the last few days there were no coronal mass ejections detected.

Posted by: nprev Jul 24 2009, 05:43 PM

Thank you very much, Z! smile.gif Looks like the Sun is showing signs of coming out of this prolonged minimum, finally.

Posted by: tedstryk Jul 26 2009, 12:40 PM

So great that they are releasing nice images and movies. When Coronas-F imaged an eclipse, images were next to impossible to come by.

Posted by: Zvezdichko Aug 1 2009, 09:03 AM

And there's more! Looks like we have a LIVE IMAGE page entitled "Solnce Segodnya" which means "The Sun Now" in Russian:

Here it is:

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

Several hints:

изображение фотосферы = image of the photosphere.

изображение магнитного поля = image of the magnetic field

изображение короны = image of the corona

изображение солнечного ветра = image of the solar wind.

изображение переходного слоя = ?? (don't know how to translate it properly)...


Posted by: Zvezdichko Aug 1 2009, 09:15 AM

http://tesis.lebedev.ru/

I noticed that the main page has several important additions. The first one is "Прогноз космической погоды" which means "Space Weather Forecast"... There's information about
'Магнитные бури в последние 24 часа" which means "Magnetic Storms in the past 24 hours". If you see something like: "Не наблюдались", this means that there are no Magnetic storms observed. "Магнитные бури в ближайшие 24 часа" is a forecast for the next 24 hours. If you see "Не ожидаются" or something like that - it means that no Storms are expected.

This is the current forecast for tomorrow.

"Текущая активность Солнца" shows the current activities of the Sun. "Поток радиоизлучения" means "A stream of electromagnetic radiation" or something like that. The next two fields mean "Average planetary A-index" and "Average planetary Kr-index". I really don't know what this means. Maybe you will help me?

The next addition is "Группы пятен и активные области" - This shows the current status of the solar spots and areas of activities. If you read "Нет активных областей" this means there are no active areas observed.

Posted by: Sunspot Aug 1 2009, 10:15 AM

But aren't those SOHO images?

Posted by: Zvezdichko Aug 1 2009, 10:19 AM

Looks like the currently images are of SOHO. Not sure if this is temporary, but I hope so! They are very, very, very outdated compared to the images published on the official website of SOHO.

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.

Well, if it isn't repeatable, it isn't science.

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

Posted by: Zvezdichko Dec 13 2009, 10:07 AM

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.

Posted by: Sunspot Dec 13 2009, 10:17 AM

This is disappointing .

Posted by: Zvezdichko Dec 13 2009, 11:16 AM

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

Posted by: Hungry4info Dec 18 2009, 04:56 PM

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?

Posted by: Zvezdichko Dec 18 2009, 05:47 PM

I can't confirm that the chemical batteries are made by the same manifacturer. True or false, they should be checked and tested before launching PG

Posted by: Zvezdichko Dec 18 2009, 06:30 PM

SDO has a very friendly Facebook chatter and IIRC according to him it is probably going to be the last delay. We have the rocket.

Posted by: mchan Dec 19 2009, 01:50 AM

That is unfortunate. I am reminded of a similar mission ending failure on Seasat after a few months operation some 30 years ago. It was also a power system problem. Space is hard and unforgiving of mistakes.

Posted by: Big_Gazza Dec 19 2009, 08:52 AM

I'm still having problems coming to terms with this failure. How depressing that the (apparent) loss of this fine instrument is due to the use of dodgy batteries, a well-established technology that should by now be rock-solid and present a near-zero risk.

I hope they pin-point the fault, then nail the guilty party (sub-contractor). Hang 'em high and let them serve as a lesson to others laugh.gif

Posted by: nprev Dec 19 2009, 09:20 AM

To give the KF team their due: Project management/complex product development is very difficult. Spaceflight is an order of magnitude or more so. Sometimes the miracle is that it ever worked at all; sometimes the real payoff is the lessons learned.

Posted by: Zvezdichko Dec 19 2009, 09:43 AM

I have my explaination why this happened, but I'm not sure this is the right place to share (involves political and economy issues).

Anyway, I'm giving a facebook account if anybody wants to go into a detailed discussion with me: www.facebook.com/svetoslav

After all, I'm again disturbed by the fact that Roscosmos and most of the official several sites are silent - just like after the delay of Phobos-Grunt.

Anatoly Perminov cautiously announces that we finally have information (this probably means a signal) from Koronas-Foton. It's too early to talk about restoration of the scientific mission because the batteries need to be charged. According to plans the scientific instruments should be turned on during the first days of January.

Fingers crossed, Koronas-Foton! If true, this is a true miracle!

30th december 2009

Today we had the last meeting of the GOGU (Which is the Lead Operation Team). According to them they couldn't confirm yesterday's announce of Roscosmos about the restoration of Koronas-Foton. The satellite continues being in its previous state and the last contact occured on 10th of december.

How utterly bizarre. Does this mean Roscosmos should no longer be considered a credible source? blink.gif

I really don't know how to comment this. My personal opinion is that there is some kind of miscommunication between Koronas-Foton engineering team and Perminov.

Koronas-Foton entered the orbit with a maximum illumination, but engineers were unable to restore the performance of the spacecraft. TESIS team confirms that there is no radio link with the spacecraft since December 11th 2009. Actually, they are not talking about "restoring the science program". They are talking about obtaining a radio signal from the spacecraft. Koronas-Foton is silent.

There's still no explaination why Roscosmos (specifically its head Anatoly Perminov) told us that engineers have restored the functionality of Koronas-Foton and there is a radio link between the spacecraft and Earth controllers.

I also don't have any good explanation.
But think about: when was the last time you heard any bad news from official Roscosmos sources?

The answer to your question is: When Phonos-Grunt got delayed for two years. It wasn't announced on the front page, but it's still on the website of Roscosmos - though on a well hidden page.
