Hi,
as I have been trying lately several times to lift off with the Atlantis and dock to the ISS, I was interested to see the parameters of the recent SpX-Dm1 NASA mission (the SpaceX Falcon 9 that lifted off early this morning from Cape Canaveral). I was expecting, as in my simulations, that lift off happened when the ISS was near the launch site, but looking up (www.satflare.com) it seems that the ISS at that time was orbiting over the Middle East!
Also, from the NASA video feed, it seems that after SECO (secondary engine cut-off) altitute was about 200km, and not 350-400 km, so quite far from the ISS orbit altitude.
I know that NASA is right and I am wrong, of course , but can someone explain me how this mission profile works? I tried to find more data on the Internet but so far no luck. Will the ship use its own engines to raise its orbit from 200km to 400k (it seems a lot ...)? And how has the launch window been determined compared to the ISS position?
Thanks,
Roberto
