History

edit

Founding and funding (2015-2023)

edit

Relativity Space was founded in 2015 by CEOTim Ellisand CTOJordan Nooneon the idea that existingprivate spaceflightcompanies were not tapping enough into the potential ofadditive manufacturing(3D printing).[6]Relativity is aiming to be the first company to successfully launch a fully 3D-printedlaunch vehicleinto orbit.[7]

In November 2020, Relativity Space announced itsUS$500 millionSeries Dfunding at a calculated US$2.3 billion valuation.[8]In June 2021 Relativity announced anotherUS$650 million funding round led byFidelity Investmentsat a valuation ofUS$4.2 billion, bringing its total funding to US$1.335 billion.[9]The funding will help the development of a partially reusableheavy-lift launch vehicle,theTerran R,targeting a first orbital launch no earlier than 2026.[10]Relativity Space has investors includingBaillie Gifford,Blackrock,BOND,Coatue,Fidelity, General Catalyst,ICONIQ Capital,K5 Global,Mark Cuban,Playground Global,Social Capital,Tiger Global,Tribe Capital,andY Combinatoramong others.[11]

In June 2022, it was reported that Relativity Space would sendOneWeb’ssecond-gen broadband satellites to orbit in 2025. The mission is to be completed using theTerran R,which marked a total value of binding launch deals for that rocket to over $1.2 billion despite the company having yet to have launched their first rocket.[12]

First launches (2023)

edit

The company's initial attempt to launch its first rocket, namedTerran 1,on March 8, 2023 was scrubbed due to technical issues, with a second attempt anticipated for March 11, 2023, which was also scrubbed.[13][14]

On March 23, 2023 (UTC) the company launched its first rocket, but it experienced failure during its second stage of flight and failed to reach orbit. Terran 1 featured no payload.[15][16]Following the failed launch, Relativity retired the rocket in favor of developing the much larger, reusableTerran Rvehicle.[17]

The company was named as a CNBC Disruptor for the 5th straight year, a listing of private companies challenging the status quo in their respective industries.[18]

Facilities

edit

Headquarters

edit

Relativity Space announced a new 11,000-square-metre (120,000 sq ft)Long Beach, Californiaheadquarters and factory in February 2020.[19]As of February 2020,the new headquarters is planned to house both business operations and Relativity'sautonomousdevelopment operations that the company plans to build into a modern rocket manufacturing factory in the coming years.[20]According to an interview with CEO Tim Ellis in early 2020, the factory is planned to have no fixedtooling,which is hoped to allow it to be rapidly reconfigured and autonomous.[21]A new 93,000-square-metre (1,000,000 sq ft) factory was announced in June 2021, with Relativity set to takeover the former Boeing C-17 production plant in January 2022 to begin production of its Terran R reusable launch vehicle.[22]In 2024, with the headquarters building completed, the company looked to have permitting approved for a 200 foot tall test stand. The application is in progress.[23]

Stennis Space Center

In March 2018, Relativity Space signed a 20-year lease at theStennis Space Centerin Mississippi, aNASArocket testing facility, to test engine components and eventually full-scale test their Aeon 1 rocket engines.[3][8]And in June 2019, Relativity Space expanded their work with the Stennis Space Center to include exclusive use of 20,000 m2(220,000 sq ft) within Building 9101.[24]In mid-2019, Relativity Space planned to create 200 jobs and invest US$59 million in Mississippi over the course of this nine-year lease, which carries an option to extend for another 10 years.[24]In late 2023, the company expanded its presence at the site with an agreement to lease the A-2 test stand in order to perform vertical testing on Terran R.[25]

Cape Canaveral LC-16

edit

In January 2019, Relativity Space announced that it won a competitive bidding process with theUnited States Air Forceto build and operateLaunch Complex 16(LC-16) atCape Canaveral Space Force Stationin Florida.[26]LC-16 has historical significance having been previously used by theUS militaryto launchTitanandPershingballistic missiles.[26]In April 2024, the company shared an update on the site that initial groundwork for the Terran R launch pad was complete with water line installation in progress.[27]

Vandenberg Space Force Base Building 330

edit

In June 2020, Relativity Space announced it plans to develop a second launch pad atVandenberg Space Force Basein California to launch payloads intopolar orbitsandSun-synchronous orbits,including theIridiumsatellite launches, between 2023 and 2030.[28]

Launch vehicles

edit

Terran 1

edit
Main article:Terran 1

Terran 1was anexpendable launch vehiclethat consisted oftwo stages.The first stage used nine Aeon 1 engines, while the second stage used a single vacuum-optimized Aeon 1 engine. It was designed to launch a maximum payload of 1,250 kg (2,760 lb) to 185 km (115 mi)low Earth orbit(LEO), normal payload of 900 kg (2,000 lb) to 500 km (310 mi)Sun-synchronous orbit(SSO), and high-altitude payload of 700 kg (1,500 lb) to 1,200 km (750 mi) SSO. Relativity's advertised launch price was US$12 million per Terran 1 mission in June 2020.[28]Relativity conducted the first launch of Terran 1 on March 23, 2023 (UTC) after three scrubbed launch attempts.[29] Soon after launch, an anomaly occurred with the upper stage engine which prevented the rocket from achieving orbit. The second stage engine and nosecone splashed into the ocean about 4 minutes into the flight.[16]The Terran 1 rocket was retired after this failed maiden flight.[17]

Terran R

edit
Main article:Terran R

Terran R is aheavy-lifttwo-stage,partiallyreusable launch vehiclethat is currently under development. Compared to the smaller, expendable Terran 1, it is constructed using the same 3D printing technologies, but is substantially larger, with a maximum payload capacity of 33,500 kg (73,900 lb) tolow Earth orbit.The first stage will use 13 Aeon R engines, while the second stage will use an upgraded Aeon Vac engine. With this design, Relativity is aiming to significantly exceed the Falcon 9 payload to low-Earth orbit. The first launch is expected to take place no earlier than 2026.[10]

Rocket engines

edit

Aeon 1

edit

The Aeon 1 rocket engine is designed to produce 23,000 pounds-force (100,000 N) atsea leveland 25,400 pounds-force (113,000 N) in a vacuum. The engine is powered byliquid natural gas(LNG) andliquid oxygen(LOX). It is made out of a proprietary 3D-printedalloy.(GRCop[30]) It is printed byselective laser sinteringand assembled from fewer than 100 parts.[31]By February 2022, Relativity Space had completed 500+ test firings of its Aeon 1 engine,[32]using the E-3 test facility at NASA's Stennis Space Center.[8]

The vacuum-optimized version of Aeon 1, known asAeonVac,powers the second stage of Relativity's rockets.[33][34]

Aeon R

edit

The Aeon R engine, currently under development, is a high pressure gas generator cycle LOX/subcooledMethane propellants engine[35]designed to produce 258,000 lbf (1,150 kN) of thrust at sea level and 279,000 lbf (1,240 kN) in a vacuum. 13 Aeon R engines will power the first stage of Terran R with a combined liftoff thrust of 3,354,000 lbf.[36]

Stargate

edit

In order to3D printlarge components such as rocket tanks and airframes, Relativity Space has created a system named Stargate, which it claims is the world's largest 3D printer of metals.[37][38]Stargate uses existing welding technology to melt metal wire, layer by layer, into precise and complex structures that have minimal joints and parts.[39]The company 3D-printed 85% of their Terran 1 launch vehicle as of 2023 and aims to print 95% of the launch vehicle in the future.[40]The company plans to eventually 3D-print a complete launch vehicle within 60 days.[41][8]

Relativity Space publicly announced their contract withMu Spacein April 2019. It is expected that Relativity Space will launch a Mu Space satellite to low Earth orbit in the second half of 2022, aboard Relativity's Terran 1 rocket.[44]

In May 2019, Relativity Space signed a contract withSpaceflight Industries,asatellite rideshareand mission management provider, to launch Spaceflight's dedicatedsmallsatrideshares. The terms of this deal were not disclosed, however, it was shared that the contract included one launch of Relativity's Terran 1 rocket in the third quarter of 2021, with an option for an unspecified number of additional launches.[45]

In September 2019, Relativity Space andMomentus Spaceannounced their launch service agreement at the 2019 World Satellite Business Week inParis.The agreement stated that Relativity's Terran 1 launch vehicles will carry Momentus'Vigoridespace tugservice vehicles into orbit. The contract is for one launch, with an option for five additional missions.[46]

In June 2020, Relativity Space announced that they signed a new launch contract withIridium.[42]This contract included up to six dedicated launches to deploy ground spare satellites tolow Earth orbit(LEO) forIridium NEXT's constellationon Relativity's Terran 1 vehicle. According to Suzi McBride, Iridium's COO, the satellite communication provider chose to partner with Relativity Space because of their flexible launch capability and the company's ability to launch one satellite at a time.[47]According to the deal these launches will not begin earlier than 2023.[47]

Lockheed Martinannounced on 16 October 2020, that it will launch acryogenicliquid hydrogen management demonstration mission on Terran 1. Lockheed Martin also specified that the launch will make use of Momentus' Vigoride orbital transfer vehicle to house the cryogenic payload.[48]This announcement came two days after NASA announced the recipients of its Tipping Point awards.[49]

OneWebannounced on 30 June 2022 that it signed the first contract for Terran R launches, with a value of over $1.2 billion for more than 20 launches starting in 2025.[50]
