If things go well it could move up to the 5th. Final date won't be set until the Flight Readiness Review next week, and as usual, until the SRBs are lit we won't know the real launch time. There has been a slight change in the planned trajectory, yielding a slightly different orbit, so here is a new set of Keplerians: STS-37 1 00037U 91 96.64650463 .00023000 17236-3 0 53 2 00037 28.4678 237.9647 0006745 281.2842 78.7272 15.37848888 29 Satellite: STS-37 Epoch time: 91096.64650463 Element set: JSC-005 Inclination: 28.4678 deg Space Shuttle Flight STS-37 RA of node: 237.9647 deg Keplerian Elements Eccentricity: .0006745 from pre-launch post OMS-2 vector Arg of perigee: 281.2842 deg Launch: 06 APR 91 14:17 utc Mean anomaly: 78.7272 deg Mean motion: 15.37848888 rev/day W5RRR Decay rate: 2.30E-04 rev/day^2 NASA Johnson Space Center Epoch rev: 2 -- Gary Morris - N5QWC/W5RRR Internet: garym@crash.cts.com Lockheed UUCP: moray!avocado!garym (home) Houston, Texas Phone: +1 713 283 5195
