Question 1
the sts fuell tank is allways full no matter the weight of the payload ?
i mean the max payload weight is 24400kg so ok the tank is full, but if the
payload is 12200kg they still full it ?

Question 2
When i orbit the fuel tank is following me ,shouldn't it suppose to deorbit ?
or am i am not doing things right ?

Question 3
What is the current developing status of orbiter ?
has a new beta been released ?

Q1: Always filled to 100% as this includes something known as performance margin. Performance margin is above the required amount of performance of the MPS so if there's a problem, they can still make either the ATO targets or the nominal MECO targets.

Q2: You're not doing things right. You're supposed to be on a sub-orbital trajectory following MECO and ET sep requiring an OMS burn near the apogee to raise the perigee out of the atmosphere.

Q3: http://orbitervis.wiki.sourceforge.net/OrbiterPublicBeta

q1 wikipedia say that STS can reach GTO ( 35.786 km ) with payload 3810 kg i cant pass 3.000 km with payload 0kg.... ?

q2 a lua script can be terminated ? it seems that once they run they run forever.

q3 how can i calculate the density of the atmosphere versus the altitude
is there an equation for that ?

Q1: Not true. The Space Shuttle is a LEO vehicle.

Q1: No, but it was once able to transport payloads into GTO, by giving them a Payload Assist Module, suitable for the size of the satellite.

Q2: No idea.

Q3: You can interpolate it for small altitude regions with a scale height and exponential function, but don't ask me the correct formula just by my head. I fear I might give you the wrong one. For the whole atmosphere, you need a complex atmosphere model usually.

EDIT: Here is the correct formula:

Q1: Partially true, payloads can reach GTO and then GEO with an upperstage carried in the Orbiter, but the Orbiter itself can not reach higher than about the height of Hubble.

i see.. so it isnt my fault.

u know i had this idea for addon to carry as a payload the last stage of an Ariane 3 missile to go to the moon with one person on board.. could be made for real cz the part fits in the payload bay and has room for a small cockpit.

thanx for the link urwumpe
