Space Exploration Technologies Corp., commonly referred to as SpaceX, is an American space technology company headquartered at the Starbase development site near Brownsville, Texas. Since its founding in 2002, the company has made numerous advancements in rocket propulsion, reusable launch vehicles, human spaceflight and satellite constellation technology. As of 2024, SpaceX is the world's dominant space launch provider, its launch cadence eclipsing all others, including private competitors and national programs like the Chinese space program. SpaceX, NASA, and the United States Armed Forces work closely together by means of governmental contracts.
The Space Launch System (SLS) is an American super heavy-lift expendable launch vehicle used by NASA. As the primary launch vehicle of the Artemis Moon landing program, SLS is designed to launch the crewed Orion spacecraft on a trans-lunar trajectory. The first SLS launch was the uncrewed Artemis I, which took place on 16 November 2022.
SpaceX Starbase—previously, SpaceX South Texas Launch Site and SpaceX private launch site—is an industrial complex and rocket launch facility that serves as the main testing and production location for Starship launch vehicles, as well as the headquarters of the American aerospace manufacturer SpaceX. Located at Boca Chica, near Brownsville, Texas, United States, and adjacent to South Padre Island, Texas, Starbase has been under near-continuous development since the late 2010s, and comprises a spaceport near the Gulf of Mexico, a production facility at Boca Chica Village, and a test site along Texas State Highway 4.
A super heavy-lift launch vehicle is a rocket that can lift to low Earth orbit a "super heavy payload", which is defined as more than 50 metric tons (110,000 lb) by the United States and as more than 100 metric tons (220,000 lb) by Russia. It is the most capable launch vehicle classification by mass to orbit, exceeding that of the heavy-lift launch vehicle classification.
Artemis III is planned to be the first crewed Moon landing mission of the Artemis program and the first crewed flight of the Starship HLS lander. Artemis III is planned to be the second crewed Artemis mission and the first crewed lunar landing since Apollo 17 in December 1972. As of December 2024, NASA officially expects Artemis III to launch no earlier than mid-2027 due to heat shield issues on Orion and valve problems in the spacecraft's life support system.

Starship is a two-stage fully reusable super heavy-lift launch vehicle under development by American aerospace company SpaceX. On April 20, 2023, with the first Integrated Flight Test, Starship became the most massive and most powerful vehicle ever to fly. SpaceX has developed Starship with the intention of lowering launch costs using economies of scale, aiming to achieve this by reusing both rocket stages by "catching" them with the launch tower's systems, increasing payload mass to orbit, increasing launch frequency, mass-manufacturing the rockets and adapting it to a wide range of space missions. Starship is the latest project in SpaceX's reusable launch system development program and plan to colonize Mars.
The Artemis program is a Moon exploration program led by the United States' National Aeronautics and Space Administration (NASA), formally established in 2017 via Space Policy Directive 1. It is intended to reestablish a human presence on the Moon for the first time since the Apollo 17 mission in 1972. The program's stated long-term goal is to establish a permanent base on the Moon to facilitate human missions to Mars.
Spaceflight in 2025 promises to follow the 2020s trend of record breaking orbital launches and increased developments in lunar, Mars and low-earth orbit exploration.
Starship HLS is a lunar lander variant of the Starship spacecraft that is slated to transfer astronauts from a lunar orbit to the surface of the Moon and back. It is being designed and built by SpaceX under the Human Landing System contract to NASA as a critical element of NASA's Artemis program to land a crew on the Moon.
A Human Landing System (HLS) is a spacecraft in the U.S. National Aeronautics and Space Administration's (NASA) Artemis program that is expected to land humans on the Moon. These are being designed to convey astronauts from the Lunar Gateway space station in lunar orbit to the lunar surface, sustain them there, and then return them to the Gateway station. As of 2024 NASA intends to use Starship HLS for Artemis III, an enhanced Starship HLS for Artemis IV, and a Blue Origin HLS for Artemis V.
Starship flight test 1 was the maiden flight of the integrated SpaceX Starship launch vehicle. SpaceX performed the flight test on April 20, 2023. The prototype vehicle was destroyed less than four minutes after lifting off from the SpaceX Starbase in Boca Chica, Texas. The vehicle became the most powerful rocket ever flown, breaking the half-century-old record held by the Soviet Union's N1 rocket. The launch was the first "integrated flight test," meaning it was the first time that the Super Heavy booster and the Starship spacecraft flew together as a fully integrated Starship launch vehicle.
Super Heavy is the reusable first stage of the SpaceX Starship super heavy-lift launch vehicle, which it composes in combination with the Starship second stage. As a part of SpaceX's Mars colonization program, the booster evolved into its current design over a decade. Production began in 2021, with the first flight being conducted on April 20, 2023, during the first launch attempt of the Starship rocket.
Starship is a spacecraft and second stage under development by American aerospace company SpaceX. Stacked atop its booster, the Super Heavy, the pair compose SpaceX's super heavy-lift space vehicle, also called Starship. The spacecraft is designed to transport both crew and cargo to a variety of destinations, including Earth orbit, the Moon, and Mars. It's designed to be reusable and capable of landing propulsively by firing its engines to perform a controlled descent in the arms of a tower on Earth or with landing legs on other planetary bodies. It is intended to enable long duration interplanetary flights with a crew of up to 100 people. It will also be capable of point-to-point transport on Earth, enabling travel to anywhere in the world in less than an hour. Furthermore, it will be used to refuel other Starship spacecraft, enabling them to reach higher orbits and other space destinations. Elon Musk, the CEO of SpaceX, estimated in a tweet that eight launches would be needed to completely refuel a Starship in low Earth orbit, enabling it to travel onwards.
Starship flight test 7 was the seventh flight test of a SpaceX Starship launch vehicle. Flight 7 lifted off from Orbital Launch Pad A (OLP-A) on January 16, 2025, at 22:37:00 UTC at the Starbase launch site in Texas. The prototype vehicles flown were Booster 14, a Block 1 vehicle, and Ship 33, the first Block 2 upper stage, which introduced upgrades in structure, avionics, and other systems. The mission was to follow a trajectory similar to the previous flight, with a planned splashdown in the Indian Ocean about an hour after liftoff, to be imaged by a NASA observation aircraft. It also tested a new Starlink satellite deployment system.
Starship flight test 8 will be the eighth flight test of a SpaceX Starship launch vehicle. Ship 34 and Booster 15 are expected to fly on this test flight. It is expected to be the second flight of a Block 2 ship. After Flight 6, Elon Musk stated that flight 8 could be the first 'catch' of the Ship should flight 7's landing be successful. Due to the failure of S33 to complete its ascent burn, this will likely be delayed to a later mission, along with the likely required insertion into Low Earth orbit. SpaceX is expected to perform the flight test in early 2025.
