Key takeaways

Relativity Space belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Relativity Space to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Relativity Space Inc. is an American aerospace manufacturing company headquartered in Long Beach, California. Relativity Space is developing launch vehicles, rocket engines, and manufacturing technologies for commercial orbital launch services. As of March 2025, Relativity has announced plans to launch its in-development launch vehicle Terran R for the first time in late 2026.

History

Founding and funding Relativity Space was founded in 2015 by CEO Tim Ellis and CTO Jordan Noone. It was founded to develop and manufacture small-lift rockets capable of carrying satellites into orbit, before pivoting to developing medium-to-heavy lift rockets to meet market demands. In November 2020, Relativity Space announced its US$500 million Series D funding at a calculated $2.3 billion valuation. In June 2021 Relativity announced another $650 million funding round led by Fidelity Investments at a valuation of $4.2 billion, bringing its total funding to $1.335 billion. The funding will help the development of a partially reusable heavy-lift launch vehicle, the Terran R, targeting a first orbital launch no earlier than 2026. Relativity Space has investors including Baillie Gifford, Blackrock, BOND, Coatue, Fidelity, General Catalyst, ICONIQ Capital, K5 Global, Mark Cuban, Playground Global, Social Capital, Tiger Global, Tribe Capital, and Y Combinator among others. In March 2025, former Google CEO Eric Schmidt replaced Ellis as CEO of Relativity Space, taking a controlling interest in the company. At this point in time, the company had a contract backlog of over $2.9 billion for Terran R.

Development history The company's initial attempt to launch its first rocket, named Terran 1, on March 8, 2023 was scrubbed due to technical issues, with a second attempt anticipated for March 11, 2023, which was also scrubbed. On March 23, 2023, Relativity launched its first Terran 1 flight, naming it "Good Luck, Have Fun" and carrying no payload. It achieved its primary mission objective to reach the area of maximum aerodynamic pressure (max-q), but experienced an anomaly during stage two burn and failed to reach orbit. In April 2023, Relativity Space announced it would retire the smaller vehicle to concentrate on its larger, reusable Terran R launch system. The heavier‑lift, partially reusable system is capable of serving satellite constellation and commercial launch markets.

Facilities

Headquarters Relativity Space announced a new 11,000 m2 (120,000 sq ft) Long Beach, California headquarters and factory in February 2020. Terran 1 was manufactured at this location, which houses additive manufacturing, research and development facilities. A new 93,000-square-metre (1,000,000 sq ft) factory was announced in 2021, with Relativity taking over the former Boeing C-17 production plant in 2022 to begin production of its Terran R reusable launch vehicle. By 2025, the Long Beach facility had become the central hub for Terran R design, manufacturing, and component testing. The facility houses testing infrastructure for the Terran R development program, such as structural test stands where primary rocket structures have undergone multi‑week static and dynamic load campaigns. The facility includes auxiliary test areas for early component verification, including cryogenic test zones and environmental test environments designed to simulate launch conditions through vibration, thermal, and pressure assessments.

Stennis Space Center

Relativity is the largest commercial tenant of NASA's Stennis Space Center in Hancock County, Mississippi, with over 300 acres of testing infrastructure. The space center was established in the 1960s, and supported the Apollo, Space Shuttle, and Constellation programs. In recent years, the center has become a hub for commercial space companies. In March 2018, Relativity Space signed a 20-year lease at the Stennis Space Center to test engine components and eventually full-scale test their fully integrated rocket engines. 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. In mid-2019, Relativity Space planned to create 200 jobs and invest $59 million in Mississippi over the course of this nine-year lease, which carries an option to extend for another 10 years. 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 stage testing on Terran R. Upgrades to the stand will increase thrust capacity from its original 650,000 lb to over 3.3 million lb, enabling more powerful stage tests and accelerated test cycles.

Cape Canaveral LC-16 In January 2019, Relativity Space announced that it won a competitive bidding process with the United States Air Force to build and operate Launch Complex 16 (LC-16) at Cape Canaveral Space Force Station in Florida. LC-16 has historical significance having been previously used by the US military to launch Titan and Pershing ballistic missiles. As of 2026, LC‑16 is undergoing significant upgrades to support Terran R, including construction of a horizontal integration facility, installation of propellant tank farms and water deluge systems, a flame diverter trench, and groundwork for additional pad support structures.

Vandenberg Space Force Base Building 330 In 2020, Relativity Space announced plans to develop a second launch pad at Vandenberg Space Force Base in California to launch payloads into polar orbits and Sun-synchronous orbits.

Worked examples

Example 1 — a first encounter with Relativity Space

Start with the simplest possible case. Write down what Relativity Space claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Relativity Space before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Relativity Space ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Relativity Space

In research: Relativity Space appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Relativity Space in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Relativity Space is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2015 establishments in California, Aerospace companies of the United States, Companies based in Long Beach, California, so understanding it makes those chapters shorter.
In everyday life: Look for Relativity Space outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
