Argo Space Corp.

California company (El Segundo address in its federal award records) that says it is designing, building and operating water-propelled in-space transport vehicles. It says it will later source its water propellant from the Moon, using its own technology to extract low-concentration water from lunar regolith; that technology is described only by the company. NASA awarded it an SBIR Phase I contract in 2023 for its Argonaut transfer stage, and ispace announced in March 2026 an agreement for Argo to deliver an ispace satellite to lunar orbit.

Demonstrated

None for space resources. The company describes its initial spacecraft, Argonaut Demo (mission Navigator), that uses water launched from Earth as propellant; no lunar water-harvesting hardware or test result is described in the sources reviewed.

Claimed or planned

Argo says its transport services run on water launched from Earth today and will later use water from the Moon, and that its processing technology targets low-concentration water in regolith with minimal power input. The abstract of its 2023 NASA SBIR Phase I award says the vehicle's water propellant could be refuelled through in-situ resource utilization on the lunar surface.

    ispace agreement for Argo Space to deliver a satellite to lunar orbit

    AgreementArgo Space Corp.With ispace, inc.

    ispace announced that it had reached an agreement with Argo Space Corp. to deliver one ispace satellite to lunar orbit using an in-space transportation vehicle, as the initial step of its planned Lunar Connect communication service, with services targeted to start as early as 2027 (ispace Mission 2.5). The agreement concerns satellite transport, not resource activity.

Open evidence gaps

  • Founding year and corporate registration were not checked; the El Segundo address comes from SBIR.gov records (earliest award 2023), and the company site gives no address.
  • Argo's lunar water-harvesting and processing technology is described only by the company; no test result, award or flight for it was found.
  • No lunar-surface mission, lander booking or date for sourcing lunar water is stated.
  • The 17 September 2026 finalized ispace-U.S. contract and the 2 October 2026 Mission 1 recap were seen only as headlines on the company news list; whether the Navigator spacecraft launched and how it performed are not established here.
  • Argo's transport vehicles currently use water launched from Earth; transport services alone are not space-resource activity.
