From Mercury & Apollo Missions to the Space Shuttle Program, Mars Rover Landings, & Artemis II.

NASA is moving into a new phase of space exploration, with major progress across human spaceflight, science missions, and advanced technology. In just one year, the agency has launched multiple crewed and science missions,

Even as NASA celebrated the rollout of the Space Launch System rocket and Orion spacecraft for Artemis II over the weekend, NASA's new administrator, Jared Isaacman, made sure to put an asterisk on the program's future.

NASA's space shuttle Challenger completed 10 missions before it broke apart during a launch in 1986, killing seven astronauts.

Researchers from NASA and GE Aerospace have conducted a power extraction test of a hybrid aircraft engine being developed under the space agency’s Hybrid Thermally Efficient Core, or HyTEC, program.
