The Defense Advanced Research Projects Agency (DARPA) is seeking industry input on the viability of developing and fielding very low Earth orbit (VLEO) satellites for use by the US armed forces, according to a pair of recent solicitations.

Project Otter, as envisioned, will assist DARPA in evaluating potential industry solutions to “develop and demonstrate ‘air-breathing' electric propulsion technologies enabling extended satellite operations in very low Earth orbit”, according to a programme summary included in a 15 June solicitation. Project Otter, which is expected to begin in earnest in fiscal year (FY) 2024, represents the agency's main thrust towards developing a potential VLEO capability.

“DARPA is exploring ideas to help frame future VLEO program investments, with a focus on overcoming energy demand in a high-drag environment, [and] concepts and technologies suitable and complementary to the [VLEO] atmosphere are of interest,” according to a second agency solicitation issued on 16 June.
