Delta-H Maneuver Today at 1800 UTC

Wed, 16 May 2012

Today at 1800 UTC we will perform our 10th momentum management (Delta-H) maneuver. Data will unavailable from the SDO instruments from 1800 until 1824 UTC (2:00-2:24 pm ET) while the thrusters are fired to change the reaction wheel speeds. Reaction wheels are used to keep SDO very accurately pointed at the Sun. These burns keep the reaction wheels within their speed limits.
