Ball Aerospace's NextSat Delivers First-Rate Performance
"Following launch, the ASTRO spacecraft experienced an anomaly with the guidance and control systems. To allow time to correct the problem, control of the mated pair was shifted from ASTRO to NextSat and the OE team used NextSat's guidance system to successfully point the mated stack towards the sun. Since then, revised software has been successfully loaded and validated, and the ASTRO vehicle is currently controlling the OE stack in the planned nominal mode."
