  • Gravity Probe B - . Mass: 3,145 kg (6,933 lb). Nation: USA. Agency: NASA. Class: Astronomy. Type: X-ray astronomy satellite. Spacecraft: Gravity Probe-B. USAF Sat Cat: 28230 . COSPAR: 2004-014A. Apogee: 646 km (401 mi). Perigee: 640 km (390 mi). Inclination: 90.0000 deg. Period: 97.60 min. Gravity Probe B's mission was to confirm a prediction of Einstein's theory of relativity. The physics experiment, developed by Stanford University and Lockheed Martin, was to observe the magnitude 5 star IM Pegasi for over a year, attempting to measure the tiny shifts in the spacecraft gyroscopes' orientation caused by the Lense-Thirring gravitomagnetic (or `frame-dragging') effect. To accomplish this the spacecraft carried four gyroscopes kept at 1.8 deg Kelvin by a liquid helium dewar, laser retroreflectors and two GPS receivers for orbit determination, a drag compensation system, and a 14 cm aperture quartz telescope. The satellite was also to make an accurate measurement of the already-established gravitostatic warping of spacetime due to the Earth's mass.

  • USA 193 - . Nation: USA. Agency: Seal Beach. Class: Technology. Type: Military technology satellite. Spacecraft: USA 193. Decay Date: 2008-02-29 . USAF Sat Cat: 29651 . COSPAR: 2006-057A. Apogee: 376 km (233 mi). Perigee: 354 km (219 mi). Inclination: 58.5000 deg. Period: 91.83 min. Classifed NRO mission of uncertain objectives, possibly military observation with a mixed payload. Later it was revealed the on-board propulsion system had completely failed, putting the satellite in a rapidly-decaying orbit. The Pentagon said that the hydrazine propellant aboard consituted a risk and announced they would shoot the satellite down. The real objective may have been to demonstrate US antisatellite capability after a Chinese test in 2007. In any case, on 21 February 2008 the satellite was down to a 242 km x 257 km orbit. At 03:26 GMT an SM-3 missile was fired from the Aegis cruiser USS Lake Erie stationed west of Hawaii to intercept the satellite. The hit-to-kill warhead successfully rammed the satellite, breaking it up into 153 catalogued items of debris with perigees of 170-250 km and apogees of up to 2700 km.
