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.

Benchmark Space Systems Secures Agreement with Tesseract Space To Provide Full Spectrum of Green In-Space Propulsion Solutions for Small Satellites

BURLINGTON, Vermont, August 5, 2020 – Benchmark Space Systems, a leading provider of in-space propulsion systems for small satellites, today announced a permanent licensing partnership to integrate Tesseract Space intellectual property, assets, and staff to elevate Benchmark’s major expansion in the development, deployment and support of its exclusively non-toxic chemical propulsion solutions for global rideshare markets.

Both Benchmark and Tesseract were founded in 2017 on green propulsion technologies designed to safely and quickly deliver small rideshare satellites the last leg of their space journey to an allotted orbital location, often in hours versus weeks using electric propulsion. Benchmark’s non-toxic propulsion solutions offer as much as one-thousand times the thrust of electric systems.

BURLINGTON, Vermont, August 5, 2020 (Benchmark Space Systems PR) – Benchmark Space Systems, a leading provider of green in-space propulsion systems for small satellites, today announced an exclusive services agreement with rideshare leader Spaceflight Inc. to provide a full range of non-toxic chemical propulsion solutions designed to accelerate satellite rideshare deployments to prime orbital locations aboard its next-generation Sherpa orbital transfer vehicles (OTVs).

Announced last month, Spaceflight’s first OTV in the Sherpa-NG family, Sherpa FX, will carry 16 customer spacecraft and several hosted payloads aboard a Falcon 9 no earlier than December 2020.

Benchmark’s safe chemical propulsion will be equipped on an upgraded vehicle called Sherpa-LT as early as late next year. Benchmark’s propulsion features a patented On-Demand Pressurization System (ODPS) that securely fires up the thruster once the OTV is safely in space and deployed from the launch vehicle.
