by Lockheed Martin, and a European Service Module (ESM) manufactured by Airbus Defence and Space – the spacecraft are designed to support crewed exploration beyond low Earth orbit. Orion is equipped with solar power, an automated docking system, and glass cockpit interfaces modeled after those used in the Boeing 787 Dreamliner, and can support a crew of six in low Earth orbit and a crew of four in lunar orbit, up to 21 days undocked and up to six months docked. A single AJ10 engine provides the spacecraft's primary propulsion, while eight R-4D-11 engines and six pods of custom reaction control system (RCS) engines developed by Airbus provide the spacecraft's secondary propulsion. Although compatible with other launch vehicles, Orion is primarily designed to launch atop the Space Launch System (SLS) rocket. The first mission on that flew a fully configured Orion spacecraft and service module was Artemis 1. This flight, however, was not a manned mission and served the purpose of testing the systems of the spacecraft in the environment it was designed for. The first crewed mission Artemis 2 is planned for 2024 and will slingshot around the Moon. The following crewed Artemis 3 flight is planned for 2025 and will be a lunar landing mission. Starship Planned to be a fully reusable interplanetary spacecraft capable of carrying 100 passengers or cargo. Primarily designed for Mars missions it is to be capable of landing on all rocky planets or moons in the Solar System except Venus. For Earth launches Starship will need a two-stage configuration with the addition of a powerful first stage booster called Super-Heavy. Flights from all other planetary bodies will not require a first stage booster. Starship will require refuelling in Earth orbit to enable it to reach other Solar System destinations. Uncrewed test flights commenced in 2020 from Boca Chica, Texas. A custom crewed lunar version of Starship—Starship HLS—was selected in 2021 from three companies that developed design proposals for NASA's Human Landing System for NASA's Artemis program, with a view to land one uncrewed mission plus one crewed mission on the Moon no earlier than 2025. SpaceX plans at least five variants of Starship, two of them intended to carry crew: Cargo flights, crewed flights (except HLS), a fuel depot, a tanker version, and HLS. Gaganyaan A three-person Earth orbital spacecraft intended to be the first crewed spacecraft of the Indian Human Spaceflight Programme.
