SHERPA-FX

SHERPA-FX [Spaceflight Inc.]

The SHERPA-FX (), developed by Spaceflight Inc., is a free flying satellite deployer.

The first mission is SHERPA-FX 1, which will deploy following satellites: Umbra-SAR 2001, Hawk 2A, 2B, 2C, Astrocast 1.x1, ..., 1.x5, PTD 1, ARCE 1A, 1B, 1C, Prometheus-2 10. In addition to the separable payloads, there will be up to four, approximately 1U-sized, hosted payloads. These hosted payloads will be non-separating and will deorbit with the Sherpa-FX1 structure. The planned hosted payloads consist of the following:

• ELROI (Extremely Low-Resource Optical Identifier), a payload to be provided by Space Domain Awareness Inc. This payload does not have RF transmission but has LED lights. This payload is designed to provide for improved orbital identification and debris mitigation and is being flown for demonstration purposes.
• EyeStar-Tag, a payload to be provided by NearSpace Launch, separate from the EyeStar S3 Radio baselined on R2A, that consists of an L-band transmitter that communicates with the Globalstar constellationand an S-band uplink to receive the kill command from the ground if necessary.
• Celestis 17, a passive payload provided by Celestis that will consist of a container of capsules containing cremated human remains.
• SOARS (Space Object Automated Reporting Systems), a payload to be provided by Keplerian Technologies that consists of a UHF transponder to communicate with that company’s ground stations. It had originally been planned to be launched as SOARS on the maiden Astra Rocket-3.0 launch, but it has also been removed from the SHERPA-FX 1 mission.
