Russians really do know how to build a rocket that looks like it does not mess around. A Falcon 9 is pretty neat, but these pictures look like they are taken on a Bond movie set.

Female voice sounds through speakers: "Raising the rocket".

Alarms blare, tension mounts, popcorn gets eaten.

It's the red text. Replace a Falcon 9's blue insignia with a red one and it also gets the "Bond" style. The fairing looks like one of my old 0.90 structural panel ones. :)

That helps a bit, but just look at that stocky tower of power with more boosters than you can shake an emergency checklist at. Even the support equipment looks menacing.

As long as the winds hold, it should be fine... after all, delays or abort on Russian rockets are pretty rare (except for yesterday)

Why abort when you can point the rocket back at the ground?

(I kinda like Russian rockets, actually, but that particular crash was way too pretty to ever forget).

From RussianSpaceWeb.com:

The liftoff of the Proton-M rocket with a Briz-M upper stage is scheduled on March 14, 2016, at 12:31:42 Moscow Time (09:31 GMT, 5:31 a.m. EDT) from Pad 39 at Site 200 in Baikonur Cosmodrome. The launch vehicle will be carrying the Trace Gas Orbiter, TGO, and the Schiaparelli lander for theExoMars-2016 project.

During the initial phase of the powered flight, the three booster stages of the Proton rocket will follow a standard flight path to match an orbit with an inclination 51.55 degrees toward the Equator. The first stage propelled by six engines will separate around two minutes into the flight, followed by thesecond stage five and a half minutes after launch.

The payload fairing will split in two halves and drop off five minutes 45 seconds into the flight, during the operation of the third stage.

Nine minutes 42 seconds after launch, the Briz-M upper stage with the TGO/Schiaparelli combo will separate from the third stage of the launch vehicle, still flying on a ballistic suborbital trajectory. One minute 34-seconds after separation, Briz-M will fire its engine for the first time over Siberia. The maneuver lasting nearly four and a half minutes will insert the stack into an initial parking orbit.

The spacecraft will then fly passively for more than an hour, almost completing a revolution around the Earth before restarting its engine over Southern Russia. The maneuver extending over most of Asia will push the spacecraft into an intermediate elliptical (egg-shaped) orbit. The spacecraft will pass an apogee (highest point) over the Pacific Ocean around three hours after launch and will then begin accelerating back toward its home planet for another hour.

Around four hours into the flight, as the vehicle crosses the coast of Portugal, Briz-M will initiate its third firing. This time, the maneuver will send the stack into a transfer orbit. Shortly after completing the third firing, Briz-M will jettison its doughnut-shaped external tank.

To reach its new, much higher apogee, Briz-M with ExoMars will coast passively for nearly three hours until the Earth's gravity pulls it back yet again.

Finally, more than 10 hours after leaving Baikonur, Briz-M will initiate its fourth and final engine firing to break itself from the Earth's gravitational field and enter a Mars-bound trajectory. The maneuver will be taking place, while the spacecraft crosses the Great Lakes, Eastern Canada and the Atlantic Ocean. Less than 14 minutes later, the TGO/Schiaparelli stack will separate from the Briz-M upper stage more than 5,000 kilometers away from Earth.

The nearly empty upper stage will then perform two small braking maneuvers to make sure it never crosses path with its former passengers.

In the meantime, the TGO spacecraft should attain a stable orientation relative to the Sun and begin the deployment of its two solar panels. The deployment of the high-gain antenna is expected within first 24 hours after launch, however its use is not expected until more than two weeks after launch.

According to ESA, the 4.3-ton TGO/Schiaparelli stack would be the heaviest spacecraft launched on a path to Mars, however the claim probably counts only successful missions. The ill-fated Mars-96 and Phobos-Grunt probes, which never left the Earth's orbit, had a mass of 6.8 and 13.5 tons respectively.

A useful blog post from ESA: blogs.esa.int/rocketscience/2016/03/13/why-exomars-ride-to-space-takes-the-time-it-does

Main info:

Separation of the first, second and third stage will occur, respectively, at 43 km, 1716 m/s; 129 km, 4503 m/s; and 153 km, 7230 m/s.

The first and second stages and the payload fairing will all fall back to Earth, less than 2000 km downrange from launch site. The third stage will crash into the Pacific, 8000 km downrange.

The first Briz-M manouvre will transform the suborbital ballistic trajectory into a preliminary, circular parking orbit at 175 x 175 km of height, 51.55° of inclination. The second burn will raise it to 250 x 5000 km, period of 2 hours. The third burn will further raise it to an apogee of over 21000 km, period of 6 hours. Fourth and last burn will achieve Earth escape.

After TGO separation, Briz-M will perform two manoeuvres to avoid colliding with the probes.

mmh,

Proton fueling started at 3:31 GMT, was completed at 6:30 GMT.

greenlighted for launch at 3:50 GMT, with weather prediction ok.

Hey all,

just a thread to let you all know that ExoMars (joint venture of ESA and Roscosmos) is launching today. Launch is scheduled at 9:31 a.m. GMT (which is one hour from posting of this thread). You can watch the webcast here:

http://www.esa.int/Our_Activities/Space_Science/ExoMars/Watch_ExoMars_launch

arrival on the red planet is scheduled for 2018.

cheers,

Cirocco

just noticed that there's already a thread for this, my bad. Mods, feel free to kill/lock/merge this one.

I am watching livestream. Do you notice that everything seems to be different than NASA launching? Different somehow. Maybe it is European style vs. American style. Anyway, go for Mars.

European webcasts are indeed different from american ones. NASA has been televising their launches and operations for a lot longer than ESA, so they have a lot more experience with it. American broadcasts are usually commentated by PR people, ESA more often puts engineers and scientists directly in front of the camera. US broadcasts also tend to give more concise, bite-sized bits of information. ESA wants to say everything correctly and with all the explanations around it, which means it comes across as much more stuffy and forced.

It's also a difference in style I suppose but personally, I prefer the American style of broadcasts. This, in my view as a European, is a field where we can definitely learn a thing or two from our American colleagues.

 

Although the French do have an awesome word for "liftoff" in my opinion :P

 

EDIT: looks like a successful liftoff :)

Kourou launches for Arianespace commercial customers is less stuffy generally :) - for most commercial launches (most of the streams ;)) and even 'repeat' missions like iss launches, there's much less to explain :)

when it's a one shot science mission, even nasa streams are a bit more stuffy ;)

now, there's also the opposite end of the spectrum with waay too much, with spaceX personnel cheering for every single phase of the launch, while other companies only cheer on mission success ;)
