Lockheed Martin Orion (MPCV)

Lockheed Martin · Reusable Capsule · USA · Digital Age (2010–present)

The Orion (formally Multi-Purpose Crew Vehicle, MPCV) is an American crewed deep-space spacecraft — Lockheed Martin's NASA Artemis Programme crew capsule + the first American crew vehicle designed for cislunar + Mars-class deep-space missions. Lockheed Martin developed the Orion in 2006-2022 under NASA contract; first uncrewed flight (Exploration Flight Test-1) 5 December 2014; first cislunar flight (Artemis 1) 16 November 2022. The first crewed flight is Artemis 2 (planned September 2025). The spacecraft is the cornerstone of NASA's Artemis Program for crewed lunar return.

The Orion crew module (Lockheed Martin built) carries 4 astronauts in a 2.6 m diameter conical capsule (gross volume 9.0 m³, habitable volume 8.95 m³). Capsule mass 10,400 kg dry. The European Service Module (Airbus Defence and Space built under ESA contract for NASA) provides propulsion + power + life-support consumables — 8,600 kg dry mass with 8,600 kg of propellant. Combined Orion stack mass: ~27,000 kg. Launch vehicle: NASA's Space Launch System (SLS). Reentry: 11 km/s lunar-return velocity (vs 7.8 km/s for ISS-return Shuttle / Crew Dragon), requiring a heavier carbon-phenolic-composite heat shield (Avcoat ablative material).

Orion's service history begins with EFT-1 (2014, uncrewed Earth-orbit reentry test), Artemis 1 (November-December 2022, uncrewed 25-day Moon-circumnavigating mission — the first beyond-LEO Orion flight), + Artemis 2 (planned 2025, 4 astronauts on a circumlunar flyby — the first crewed beyond-LEO mission since Apollo 17 in 1972). Artemis 3 (planned 2026-2027) will land 2 crew on the lunar South Pole using a SpaceX Starship-derived Human Landing System docked to Orion. The Orion is also being designed for Mars-class missions in the 2030s+; the spacecraft is built for ~21-day standalone missions + much longer with Gateway or habitat support. Lockheed Martin Denver produces the crew modules; Airbus Bremen produces the service modules.

For Kids — a shorter, friendlier version

The Orion is an American crewed spacecraft built by Lockheed Martin for NASA. It is the first American crew ship designed to go beyond Earth orbit since Apollo in the 1970s. Lockheed developed Orion from 2006 to 2022. Orion is the centerpiece of NASA's Artemis program to return astronauts to the Moon.

The Orion crew capsule holds 4 astronauts. The capsule is shaped like a cone, 9 feet across at the bottom. The capsule alone weighs 22,900 pounds. A European Service Module behind it provides power and rocket engines for travel. Total Orion stack weighs about 60,000 pounds, heavier than a school bus.

Orion is launched by NASA's giant Space Launch System (SLS) rocket. After the Moon mission, Orion comes back to Earth at 7 miles per second, much faster than a rifle bullet. The Avcoat heat shield protects the capsule from 5,000-degree-Fahrenheit re-entry temperatures. Parachutes then slow the capsule for an ocean splashdown.

Orion has flown twice without people: a 2014 Earth-orbit test and the November 2022 Artemis 1 trip around the Moon. The first crewed flight (Artemis 2) is planned for 2025. Artemis 3 in 2026 will land astronauts on the Moon, the first since Apollo 17 in 1972.

Kids’ Questions

How is it different from the Space Shuttle?

The Space Shuttle was a winged spaceplane that flew in Earth orbit. The Orion is a cone-shaped capsule, like Apollo but bigger. The Shuttle could not go beyond Earth orbit; Orion is built for Moon and Mars missions. The Shuttle landed on a runway; Orion splashes down in the ocean under parachutes, like Apollo.

How is it different from Apollo?

The Apollo crew capsule held 3 astronauts; the Orion holds 4. Orion is also bigger: 9 feet across versus 11 feet for Apollo, but Orion's habitable space is larger thanks to modern packing. Orion has digital glass-cockpit screens; Apollo used dials and switches. Orion's heat shield handles Moon-return speeds (7 miles per second), the same as Apollo.

What is Artemis?

Artemis is NASA's program to return astronauts to the Moon and eventually go to Mars. Artemis 1 was an unmanned test in 2022. Artemis 2 will carry 4 astronauts around the Moon in 2025. Artemis 3 will land astronauts on the Moon in 2026, the first since 1972. Later Artemis missions will build a Moon-orbiting space station called Gateway.

Variants

Orion (Block 1, 2014): Initial test variant. EFT-1 + Artemis 1.
Orion (Block 1B, 2026+): Service variant with refinements. Artemis 3+.

Notable Operators

NASA Artemis Program (2014-present): Sole operator. Cislunar + lunar-surface missions.

Frequently Asked Questions

Why use a capsule instead of the Space Shuttle approach?

Three reasons. (1) Mass efficiency at high reentry speeds — lunar-return enters the atmosphere at 11 km/s vs the Shuttle's 7.8 km/s LEO-return; a conical capsule with ablative heat shield handles the higher heating much more efficiently than the Shuttle's reusable thermal-protection-tile orbiter (the Shuttle could not have survived a lunar-return reentry without major heat-shield redesign). (2) Crew safety — the Apollo-style abort tower allows escape during launch + early ascent, a feature the Shuttle architecturally lacked + that contributed to the Challenger + Columbia losses. (3) Reusability vs cost — the Shuttle's reusability promised low cost-per-launch but delivered ~$1.5 billion/flight; Orion + SLS are expendable but less-complex + (in lifetime accounting) likely lower-cost-per-flight for the Artemis mission profile.
