// SPACECRAFT — ESPA-Grande / microsat bus
SF-500
BETAHigh-power, agile pointing.
An ESPA-Grande microsat bus for power-hungry payloads and agile, high-rate collection.
The SF-500 steps up to ESPA-Grande, carrying ~250 kg of payload with multi-kilowatt power and agile slew for high-rate, high-resolution collection. It is the home of SAR-X and the heavy comms terminals.
Agile control-moment pointing lets it slew between targets in seconds, turning a single spacecraft into a multi-target collector across each pass.
