At Vandenberg Air Force Base in California, the Orbital Sciences Pegasus XL rocket is ready for mating to the AIM spacecraft. AIM, which stands for Aeronomy of Ice in the Mesosphere, is being prepared for integrated testing and a flight simulation. The AIM spacecraft will fly three instruments designed to study polar mesospheric clouds located at the edge of space, 50 miles above the Earth's surface in the coldest part of the planet's atmosphere. The mission's primary goal is to explain why these clouds form and what has caused them to become brighter and more numerous and appear at lower latitudes in recent years. AIM's results will provide the basis for the study of long-term variability in the mesospheric climate and its relationship to global climate change. Launch from the Pegasus XL rocket is scheduled for April 25.

Operators at NASA's John C. Stennis Space Center are completing modifications to the E-1 Test Stand to begin testing Aerojet AJ26 rocket engines in early summer of 2010. Modifications include construction of a 27-foot-deep flame deflector trench. The AJ26 rocket engines will be used to power Orbital Sciences Corp.'s Taurus II space vehicles to provide commercial cargo transportation missions to the International Space Station for NASA. Stennis has partnered with Orbital to test all engines for the transport missions.

A supermoon rises over Huntsville, Alabama, home to NASA’s Marshall Space Flight Center, Aug. 19. Visible through Wednesday, Aug. 21, the full Moon is both a supermoon and a Blue Moon. Supermoons are the biggest and brightest full Moons of the year because the Moon is within 90% of its closest point to Earth. While not blue in color, the third full Moon in a season with four full Moons is called a “Blue Moon.” Huntsville is known as the “Rocket City” because of its proximity to NASA Marshall, which manages vital propulsion systems and hardware, launch vehicles, engineering technologies, and cutting-edge science for the agency.

NASA Administrator Charles Bolden poses with an all-girl engineering team that participated in the White House Science Fair. "Team Rocket Power" was one of 100 teams that qualified for last year’s Team America Rocketry Challenge (TARC). Nia'mani Robinson, 15, Jasmyn Logan, 15, and Rebecca Chapin-Ridgely, 17, gave up their weekends and free time after school to build and test their bright purple rocket, which is designed to launch to an altitude of about 750 ft, and then return a “payload” (an egg) to the ground safely. The fourth White House Science Fair was held at the White House on May 27, 2014 and included 100 students from more than 30 different states who competed in science, technology, engineering, and math (STEM) competitions.

NASA rolled out a key piece of space flight hardware for the SLS (Space Launch System) rocket for the first crewed mission of NASA’s Artemis campaign from Marshall Space Flight Center in Huntsville, Alabama, on Wednesday, Aug. 21 for shipment to the agency’s spaceport in Florida. The cone-shaped launch vehicle stage adapter connects the rocket’s core stage to the upper stage and helps protect the upper stage’s engine that will help propel the Artemis II test flight around the Moon, slated for 2025. Manufactured by prime contractor Teledyne Brown Engineering and the Jacobs Space Exploration Group’s ESSCA (Engineering Services and Science Capability Augmentation) contract using NASA Marshall’s self-reacting friction-stir robotic and vertical weld tools. Crews moved the adapter out of NASA Marshall’s Building 4708 to the agency’s Pegasus barge Aug. 21. The barge will ferry the adapter first to NASA’s Michoud Assembly Facility in New Orleans, where crews will pick up additional SLS hardware for future Artemis missions, before traveling to NASA Kennedy. Once in Florida, the adapter will join the recently delivered core stage. There, teams with NASA’s Exploration Ground Systems will prepare the adapter for stacking and launch.

NASA rolled out a key piece of space flight hardware for the SLS (Space Launch System) rocket for the first crewed mission of NASA’s Artemis campaign from Marshall Space Flight Center in Huntsville, Alabama, on Wednesday, Aug. 21 for shipment to the agency’s spaceport in Florida. The cone-shaped launch vehicle stage adapter connects the rocket’s core stage to the upper stage and helps protect the upper stage’s engine that will help propel the Artemis II test flight around the Moon, slated for 2025. Manufactured by prime contractor Teledyne Brown Engineering and the Jacobs Space Exploration Group’s ESSCA (Engineering Services and Science Capability Augmentation) contract using NASA Marshall’s self-reacting friction-stir robotic and vertical weld tools. Crews moved the adapter out of NASA Marshall’s Building 4708 to the agency’s Pegasus barge Aug. 21. The barge will ferry the adapter first to NASA’s Michoud Assembly Facility in New Orleans, where crews will pick up additional SLS hardware for future Artemis missions, before traveling to NASA Kennedy. Once in Florida, the adapter will join the recently delivered core stage. There, teams with NASA’s Exploration Ground Systems will prepare the adapter for stacking and launch.

KENNEDY SPACE CENTER, FLA. - On Launch Complex 17-B, Cape Canaveral Air Force Station, the first stage of a Delta II rocket is lifted up the mobile service tower. Below the rocket is the flame trench, and in the foreground is the overflow pool. The rocket is being erected to launch the Space InfraRed Telescope Facility (SIRTF). Consisting of an 0.85-meter telescope and three cryogenically cooled science instruments, SIRTF is one of NASA's largest infrared telescopes to be launched. SIRTF will obtain images and spectra by detecting the infrared energy, or heat, radiated by objects in space. Most of this infrared radiation is blocked by the Earth's atmosphere and cannot be observed from the ground.

These photos show highlights from Artemis II NASA astronauts Victor Glover, Reid Wiseman, and Christina Koch of NASA and CSA (Canadian Space Agency) astronaut Jeremy Hansen visit to NASA’s Marshall Space Flight Center in Huntsville, Alabama, Nov. 27. The crew met and spoke to employees and viewed facilities for SLS (Space Launch System) rocket. All four astronauts signed the Orion stage adapter (OSA), a small ring structure that connects SLS to NASA’s Orion spacecraft, that will be used for Artemis II. Koch and Wiseman also visited the Systems Integration Lab, where SLS flight software testing is conducted. The four astronauts will launch atop SLS inside Orion to venture around the Moon on Artemis II, the first crewed flight for Artemis.

The crew met and spoke to employees and viewed facilities for SLS (Space Launch System) rocket. All four astronauts signed the Orion stage adapter (OSA), a small ring structure that connects SLS to NASA’s Orion spacecraft, that will be used for Artemis II. Koch and Wiseman also visited the Systems Integration Lab, where SLS flight software testing is conducted. The four astronauts will launch atop SLS inside Orion to venture around the Moon on Artemis II, the first crewed flight for Artemis.
