NASA’s Rossi X-ray probe makes a quiet exit after spending 22 years in orbit

(*22*)Information Transient: A month after the breakup of China’s Tiangong-1 space lab, one other spacecraft went to its fiery doom right now with far much less fanfare. Orbital assessments from the U.S. navy’s Joint Space Operations Center point out that NASA’s Rossi X-Ray Timing Explorer made its atmospheric re-entry at roughly 7:45 a.m. PT (14:45 GMT), greater than 22 years after its launch and 6 years after it was decommissioned. The 6,700-pound probe’s destruction wasn’t expected to leave much of a trace, however its legacy is enduring. The mission’s most notable contributions got here in the study of black holes and their effect on the fabric of spacetime.
