    Looking for Rocket speed/weight/altitue/time

    a graph or better still a table of a real rockets mass and speed at various points on the way up.

    I saw somewhere where the Shuttle uses 50% of total mass in the first 90 seconds.

    H2O2 is used as the oxidant in a ratio of 7.3:1 to fuel - Bit Like Skylon/Hotol in that you pick up most of the weight after takeoff. And the weight is already accelerated up to mach 0.85
    The mission profile begins with a takeoff from a conventional runway using the two takeoff rocket engines for thrust. The aircraft is loaded with all the fuel it needs for the climb from the tanker to orbit. It also has fuel and oxidizer aboard sufficient for 15 minutes of atmospheric flight. The total weight of the vehicle at takeoff is about 50,000 pounds, but by the time it achieves tanker rendezvous at 43,000 feet and 0.85 Mach number its weight has dropped to about 38,000 pounds.

    When the aircraft meets the tanker it takes on about 147,000 pounds of hydrogen peroxide. It then disconnects from the tanker and climbs to space. As it inserts into orbit, its weight has dropped to about 16,500 pounds. After performing its orbital mission, the aircraft reenters and glides to a normal landing at a runway.
