RSA Investigates a Novel High-Thrust, High-Efficiency Propulsion System

WASHINGTON, July 19, 2021 (Rhea Space Activity PR) — As U.S. operations in space steadily move further away from Earth orbit, the rapidly growing ‘New Space’ company Rhea Space Activity (RSA) is pleased to announce that it has been selected by the United States Air Force (USAF) for a Phase I, Small Business Innovation Research (SBIR) 2021 Space Force Pitch Day award to investigate a bi-modal, solar-thermal propulsion system that would provide rapid repositioning capabilities for a future United State Space Force (USSF) deep space communications spacecraft.

LOUISVILLE, Colo., June 24, 2021 (Sierra Space PR) – Sierra Space, the new commercial space subsidiary of global aerospace and national security leader Sierra Nevada Corporation (SNC), will supply the propulsion components and integration services for a Nuclear Thermal Propulsion (NTP) system under a recent contract with General Atomics Electromagnetic Systems (GA-EMS). GA-EMS and Sierra Space will develop and demonstrate an on-orbit NTP system for a Defense Advanced Research Projects Agency (DARPA) program called Demonstration Rocket for Agile Cislunar Operations (DRACO).

ARLINGTON, Va. (DARPA PR) — DARPA has awarded contracts for the first phase of the Demonstration Rocket for Agile Cislunar Operations (DRACO) program. The goal of the DRACO program is to demonstrate a nuclear thermal propulsion (NTP) system above low Earth orbit in 2025. The three prime contractors are General Atomics, Blue Origin, and Lockheed Martin.
