Hi, i am new, though i learned how to rearrange my orbit while in space, i don't know how to launch from earth (or any other planet) and get in orbit, is there a tutorial that shows that, i searched but couldn't find it.
 
Yes i did, the only thing i found is a tutorial that asks for a scenario i don't have, though there is the guide "go play in space that i forgot i had on my computer, i'll try to go and see if i can't find anything in it.
 
During a real shuttle launch, this maneuver is done for having a earlier acquisition of signal by the TDRS satellite. It has no positive effects on the trajectory (actually, a bit of fuel gets used for this rotation), but makes it possible to have a better communication with the Shuttle
 
I mean when after the srb separation, the shuttle do a quick roll to set upright and pitch up to 35, during this phase , the altitude before diminishes then returns to increase.

The autopilot make this in all STS mission:sorry:
 
Yes. Is that a problem?

The autopilot follows this trajectory as the Shuttle wants to gather horizontal velocity at minimal fuel costs. The SRBs "throw" the Shuttle, and the rest of the stack mostly concentrates on gathering velocity. Gaining or holding vertical velocity requires fuel before you are in orbit (simplified), loosing vertical velocity makes you accelerate (by the pull of gravity) and gain kinetic energy.

You can say, the space shuttle follows the way of the lowest resistance (against the pull of gravity). The Ariane V and many other launchers do actually the same maneuver. It is a common feature for all rocket-(stage)-s with small thrust-to-weight ratio.

The so called "gravity losses" are one of the worst problems for rockets. It takes about 50% of the fuel mass of a rocket to counter gravity losses during ascent.
 
Ok, thank you.:thankyou:

It is not a problem, I wanted to know only the reason of this maneuver and if effectively they came made from the shuttle or other launchers, because in Internet I have not found null with regard to.



hi :cheers:
