Certification-1 mission, the first of two launches needed to certify the rocket for National Security Space Launch (NSSL) missions. Payload from Celestis , demonstrated engine restart capability of the Centaur upper stage delivering multiple payloads to different orbits.
In May 1946, the U.S. Air Force launched the Nuclear Energy for Propulsion of Aircraft (NEPA) project to explore the potential of nuclear energy for powering aircraft. [13] [14] This initiative led to a collaborative effort of the Air Force and the U.S. Atomic Energy Commission (AEC) known as the Aircraft Nuclear Propulsion (ANP) program, aimed at developing nuclear propulsion systems for ...
Cislunar Explorers is a pair of spacecraft that will show the viability of water electrolysis propulsion and interplanetary optical navigation to orbit the Moon. [2] Both spacecraft will launch mated together as two L-shaped 3U CubeSats, which fit together as a 6U CubeSat of about 10 cm × 20 cm × 30 cm.
The RL10 was first tested on the ground in 1959, at Pratt & Whitney's Florida Research and Development Center in West Palm Beach, Florida. [6] [7] The first successful flight took place on November 27, 1963. [8] [9] For that launch, two RL10A-3 engines powered the Centaur upper stage of an Atlas launch vehicle. The launch was used to conduct a ...
The Space Force's USSF-51 launch in late 2022 was be the first national security classified mission, but in May 2021 the spacecraft was reassigned to an Atlas V to "mitigate schedule risk associated with Vulcan Centaur non-recurring design validation". [67] For similar reasons, the Kuiper Systems prototype flight was moved to an Atlas V rocket ...

The Cislunar Transporter is launched in two parts, a tug and a tanker, to low Earth orbit before refueling Blue Moon in a lunar near-rectilinear halo orbit. [11] Both MK2 and the Cislunar Transporter are to be powered by three BE-7 engines burning liquid hydrogen fuel and liquid oxygen oxidizer. [7]
Commercial Lunar Payload Services (CLPS) is a NASA program to hire companies to send small robotic landers and rovers to the Moon.Most landing sites are near the lunar south pole [1] [2] where they will scout for lunar resources, test in situ resource utilization (ISRU) concepts, and perform lunar science to support the Artemis lunar program.
