Condensation in the air as the rocket passes though layers with different humidity and shocks/decompresses the air as it approaches/exceeds the speed of sound.

Must say I don't miss the nattering jibber jabber of CNN-type yakking heads on that youtube vid!
Best of luck to the F-G team :-) |

I did watch the launch from work, with my Bulgarian colleague doing the translation from Russian to English. Normal-ne was the sweetest Russian word I learned today!
It was Mars bars for us to celebrate! No beers...we were at work! I will unlock my crossed fingers only when Fobos-Grunt will be on its way to Mars in a few hours from now! |

BTW - before any of the more extreme OCD of you say 'Whahhhhahha - it's in the Past and Future sub-forum'... I'll put it into Orbiting Spacecraft, when it goes into Martian orbit. (Same rule applies to MSL)

And it's official now, the ISS crew will try to observe the Fregat burns.
QUOTE FOBOS-GRUNT Launch: If everything goes as planned, Russia will launch its FOBOS-GRUNT (Phobos-Soil) probe to Mars tonight at 7:16pm EST on a Zenit-2SB/Fregat rocket. The Phobos Sample Return Mission PhSRM, which is also carrying a Chinese Mars satellite, Yinghuo-1, a 2nd Chinese experiment, and an experiment of the U.S. Planetary Society, will land on the Martian moon and return a soil sample (~200g) to Earth. It will also study Mars from orbit, including its atmosphere and dust storms, plasma and radiation environment. The return vehicle is scheduled to arrive back on Earth in August 2014. The spacecraft will be inserted into a 207 x 347 km elliptical orbit inclined 51.4 deg. After 2.5 hrs flight (1.7 revs) the main propulsion system will be ignited to transfer the spacecraft into an elliptical orbit of 250 km x 4150 (...4170) km, with a period of 2.2 hrs. After 2.1 hrs (1 revolution), a 2nd engine burn for TMI (Trans-Mars Injection) at 8:04:06pm EST will transfer the spacecraft into an interplanetary Earth-Mars trajectory. The ISS crew will be able to view PhSRM tonight, starting at ~7:58pm, at a range of 3248 nmi., with the spacecraft and its exhaust plume in sunlight for the entire duration of the viewing opportunity and the ISS in eclipse (darkness). If successful, Russia is back in the business of planetary exploration. Let’s all wish them well! Godspeed, Fobos-Grunt! (Hope Doug doesn't mind a tiny bit of HSF mentioned, as it's related to this mission.) Source: http://www.nasa.gov/directorates/heo/repor...orts/index.html |

Does Russia have its own DSN equivalent? Do they share with ESA at all?

First upper stage burn should be over, but as yet no news on how it went.
It was at this stage that Mars 96, Russia's last planetary launch attempt, ran into trouble. Hope all is well. |
