Shuttle Launch Postponed To July 4th

mkosmo writes "NASA has yet again delayed Space Shuttle Discovery from launching due to growing weather conditions. Next launch attempt is the afternoon of the 4th of July." From the article: "Windows of opportunity are determined by the path of the orbiting international space station, the shuttle's destination. With each passing day, the time for a launch gets earlier by 22-1/2 minutes. That could be good news for NASA because summer thunderstorms are less likely to be a problem earlier in the day."

    It's a bit of apples-to-oranges comparison. Russians do not currently operate a shuttle fleet. They launch the much smaller Soyuz / Progress vehicles, which in turn need less stringent launch conditions.

    Nobody ought to make jokes until AFTER the shuttle launch, since we don't yet know the morbid details soon to play out that will make the jokes funny or not.

    Russian space program lost 4 people in missions, in two Soyuz accidents in 70's, all on descent (one parachute failure when USSR leaders scheduled a flight for a national holiday, for political reasons, instead of launching when ready; and one outer air valve failure when they were brave/foolish enough to descend without light spacesuits.)

    US space program lost 14 people in missions, in two Shuttle accidents, one on launch and another on descent.

    Both programs had various accidents on the ground, not in missions.

    The Shuttle is as capable as Atlas V Heavy to LEO (50,000 lbs) among currently active vehicles. Proton is close at 46,000 lbs. However STS can only to to LEO, whereas Proton can (and does) go to geosynchronous orbit, delivering up to 12,000 lbs.)

    Energiya was a modular design, and could be configured to lift up to 400,000 lbs from the ground. It was flown twice in 160,000 lbs configuration (one of those flights launched Buran, which weighted about 80,000 lbs.) Given Energiya's thrust, Buran could lift up to 60,000 lbs in its payload bay, but that never happened because nobody was interested - we are not building starships yet.

    Energiya as such is not manufactured now, but it's engines - RD-180 - are used on Atlas V. The "heavy" option can lift up to 50,000 lbs to the LEO, or 26,000 lbs to the geostationary orbit.

    Shuttle has to worry about rain because, unlike the Russians, the shuttle heat shield is 1) exposed during the entire ascent instead of being tucked safely between rocket stages and 2) is made of silica glass that is glued on to the orbiter's belly. Rain=BAD
