NASA's Advanced Composite Solar Sail System has begun deployment operations. Upon an initial attempt to unfurl, the solar sail paused when an onboard power monitor detected higher than expected motor currents. Communications, power, and attitude control for the spacecraft all remain normal while mission managers work to understand and resolve the cause of the interruption by analyzing data from the spacecraft.
One of the primary objectives of this technology demonstration is to test the expanding boom system, which has never been deployed for a solar sail on a spacecraft of this size. The spacecraft's booms, which are similar in function to a sailboat's booms, are made of a new material that is stiffer and lighter than previous designs. This technology has the potential to lower the cost of deep space missions and increase access to space.
Mission operators have been able to download data from the spacecraft during brief, planned communications windows when it passes in range of mission control at Santa Clara University in California. The team is conducting analysis and assessing all spacecraft systems before resuming deployment operations.
NASA's Small Spacecraft Technology program maintains a philosophy of risk tolerance in its pursuit to rapidly mature space technologies that meet the needs of NASA and the nation.
