 Chandra X-ray Observatory:
  Deployment (STS-93)    = July 23, 1999   Data storage             = 1.8 gbs
  Science mission        = ~5 years        Length (sun shade open)  = 45.3 m
  Orbital check-out      = 2 months        Length (sun shade clsd)  = 38.7 m

 ORBITAL DATA:
  Inclination            = 28.5 degrees    Orbital period           = ~64 hours 
  Apogee altitude        = ~ 86,487 km     Observing time / orbit   = ~55 hours
  Perigee altitude       = ~  5,999 km   

 WEIGHTS & PROPULSION:
  Dry                    = 10,560 lbs      Propellant               = 2,153 lbs
  Pressurant             = 10 lb           Total launch weight      = 12,930 lb
  Engines                = 4               Thrust per engine        = 105 lb
