PAMS-STU was a NASA experimental spacecraft launched from STS 77 to test an attitude stabilization design. It had an unbalanced mass distribution and two magnetic rods. The interaction of the rods with Earth's magnetic field was expected to damp any wobble or spin. There were some problems in ascertaining the success fully because of the malfunction of the laser ranger. It reentered the atmosphere on October 26.
