Spartan 201-4



Spartan 201-4 is a reusable American solar observatory module that was released from STS 87. A computer glitch made it unable to obtain attitude control; an effort to recapture it robotically introduced a hazardous spin motion, also. Ultimately, it had to be recaptured by a space walk by two astronauts. During the three days of free-flying, its orbital parameters remained close to that of STS 87.
