Falcon 9 is a partially reusable medium-lift launch vehicle that can carry cargo and crew into Earth orbit, designed, manufactured and launched by American aerospace company SpaceX. It can also be used as an expendable heavy-lift launch vehicle. The first Falcon 9 launch was on 4 June 2010. The first Falcon 9 commercial resupply mission to the International Space Station (ISS) launched on 8 October 2012. In 2020 it became the first commercial rocket to ever launch humans to orbit and is currently the only such vehicle capable of doing so. It is the only U.S. rocket currently certified for transporting humans to the ISS. In 2022, it became the U.S. rocket with the most launches in history and with the best safety record, having suffered just one flight failure.

The Space Test Program (STP) is the primary provider of spaceflight for the United States Department of Defense (DoD) space science and technology community. STP is managed by a group within the Advanced Systems and Development Directorate, a directorate of the Space and Missile Systems Center of the United States Space Force. STP provides spaceflight via the International Space Station (ISS), piggybacks, secondary payloads and dedicated launch services.

The year 2012 saw a number of significant events in spaceflight. In May and October, the first Commercial Orbital Transportation Services resupply missions took place, during which the SpaceX Dragon became the first private spacecraft to dock with the International Space Station (ISS). In June, China launched the crewed Shenzhou 9 orbital mission, and North Korea achieved its first successful orbital launch in December. 2012 also saw China's first successful asteroid exploration mission, and the landing of NASA's Curiosity rover on Mars. The Vega and Unha-3 rockets made their maiden flights in 2012, while the Proton-K made its last.

Heavy-lift launch vehicle Launch vehicle capable of lifting between 20,000 to 50,000 kg into low Earth orbit

A heavy-lift launch vehicle is an orbital launch vehicle capable of generating a large amount of lift to reach its intended orbit. Heavy-lift launch vehicles generally are capable of lifting payloads between 20,000 to 50,000 kg or between 20,000 to 100,000 kilograms into low Earth orbit (LEO). As of 2023, operational heavy-lift launch vehicles include the Long March 5, the Proton-M and the Delta IV Heavy.
