For reasons that remain unexplained, the Solar Dynamics Observatory (SDO) did not return to science mode after it passed through the Moon’s shadow on August 2nd.
The only information about this on the SDO webpage simply states, ” The spacecraft did not go back into Science mode at the end of the transit. SDO FOT members are looking into the issue.” Spaceweather.com notes that “Since the transit no new data have appeared on SDO public websites.”
SDO has only been in orbit for six years. It would be a shame to lose it so quickly.
UPDATE: It appears that engineers are getting SDO back into operation. Hat tip James Fincannon.
