SDO Day 65: Calibration Maneuvers

The EVE cruciform maneuver was completed yesterday. Other tests included the high-gain antenna handover with stagger stepping and no-step requests. These tests are required to keep the observatory from moving too much while taking an image with HMI and possibly AIA.

Next Tuesday we plan to have an Delta-H thruster burn. These momentum unloads are required to keep the reaction wheels spinning at the correct speeds.

Next Wednesday we are having a First Light Press Conference at the Newseum in Washington, DC. Stay tuned for proof that the instruments on SDO are working great!
