New OTVs, slated to launch in 2021, will minimize the impact of extended development timelines and schedule delays while providing increased launch flexibility 

SEATTLE, November 12, 2020 (Spaceflight PR) — Spaceflight Inc., the leading satellite rideshare and mission management provider, announced today that it is developing two additional next-generation orbital transfer vehicles (OTVs) that will debut in 2021. Its first, Sherpa-FX, will fly on a fully dedicated rideshare mission with SpaceX, dubbed SXRS-3 by Spaceflight, no earlier than December 2020. The next two ESPA-class space vehicles in the company’s portfolio are designed to provide more orbital diversification, including flexible manifest changes, deployment to multiple altitudes and orbital planes, and rapid launch solutions.

MOUNTAIN View, Calif., December 14, 2017 (ACE PR) — Today we are excited to announce a major breakthrough with our new electric propulsion system, Apollo Constellation Engine (ACE). Apollo recently tested ACE in an independent lab at The Aerospace Corporation where thrust, Isp, and system efficiency measurements closely matched Apollo’s own lab tests. These results showed that ACE has 3x better impulse per kg and 3x better impulse per liter than competing thrusters on the market today. These advantages can result in a launch cost savings of $250,000+ for satellite manufacturers.
