1994-016B
The second SEDS mission was launched at 0340 on 1994 Mar 10 aboard Delta 226. The tether unreeled for 1 h 46 min and reached a vertical extent of 19.8 km. Data was returned for 10 hours.
This time the tether was left attached to Delta 226 in its 347 x 352 km x 32.3 deg orbit. The tether oscillated back and forth relative to the vertical. On Mar 13 the tether was severed by space debris at a length of 11 km; the end mass and 8-9 km of the tether reentered within hours. The tether was cut several times during its lifetime. The orbit of the Delta/tether combination decayed rapidly and by May 8 at 1200 it was in a 140 x 154 km x 32.3 deg orbit, reentering shortly afterwards.
