Terran 1 consists of two stages. The first stage is powered by nine Aeon 1 engines burning methane and oxygen propellants in a gas-generator cycle, each producing 23,000 lbf (100 kN) of thrust each. The second stage is powered by a single vacuum-optimized version of Aeon 1,[2] known as AeonVac, producing 28,300 lbf (126 kN) of thrust in vacuum.[5] Both stages will be autogenously pressurized.[citation needed]
The payload fairing measures 6.8 m (22 ft) long and has a diameter of 3 m (9.8 ft). Terran 1 is capable of up to 1,500 kg (3,300 lb) to low Earth orbit,[6] although Relativity commonly states a payload capacity of 1,250 kg (2,760 lb).[5]
The primary and secondary structures of Terran 1 are manufactured with Relativity's Stargate 3D printer out of a proprietary aluminum alloy.[6] 90% of Terran 1 by mass consists of printed components;[6] Relativity claims that they can reduce the part count in the vehicle by 100 times compared to traditionally-manufactured rockets and manufacture an entire flight article from raw materials in 60 days.[6][7] Relativity's in-development Terran R launch vehicle will utilize the same tooling used to manufacture Terran 1.[3][2]
Relativity advertised a price per launch for Terran 1 of US$10 million in 2019.[8] By 2021, the advertised price per launch had been increased to US$12 million in 2021.[2][5]
Launches
Relativity is hoping to conduct the first launch of Terran 1 in early 2022.
$3 million contract for unspecified payload(s) in NASA's Venture Class Launch Services (VCLS) 2 program.[10] The ELaNa 42 mission, consisting of three CubeSats, will launch on this flight.[11]
The 2019 contract with Momentus included a first flight originally scheduled for 2021, with option for five additional flights in the future. The five flights will include launch of a Momentus Vigoride Extended space tug.[13]
Launch site will either be Cape Canaveral or Vandenberg. TriSept stated that the launch will feature one large primary payload accompanied with several smaller payloads.[15]
This Template lists historical, current, and future space rockets that at least once attempted (but not necessarily succeeded in) an orbital launch or that are planned to attempt such a launch in the future
Symbol † indicates past or current rockets that attempted orbital launches but never succeeded (never did or has yet to perform a successful orbital launch)
