This Request for Information (RFI) continues market research for the ASTROS II requirement, supported by an Industry Day held at Edwards Air Force Base. The government has released briefing charts and an attendee roster, and invites industry to submit follow-up questions from that event. Separate from the Q&A process, the government requests a targeted capability response regarding systems engineering expertise applicable to rocket test infrastructure. All submissions are due by a specified deadline shortly after the Industry Day. No budget amounts are provided in this notice.
