The Perseverance rover is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the Red...
A United Launch Alliance Atlas V rocket with NASA’s Mars 2020 Perseverance rover onboard is seen as it is rolled out of the Vertical Integration Facility to the launch pad at Space Launch Complex 41, Tuesday, July 28, 2020, at Cape Canaveral Air Force Station in Florida. The Perseverance rover is part of NASA’s Mars Exploration Program, a long-term effort of...
This image of Jezero Crater, the landing site for the Mars Perseverance Rover, was taken by instruments on NASA’s Mars Reconnaissance Orbiter, which regularly takes images of potential landing sites for future missions. NASA chose Jezero crater as the landing site for the Perseverance rover because scientists believe the area was once flooded with wate...
Carried by a balloon the size of a football stadium, ASTHROS will use a telescope to observe wavelengths of light that aren’t visible from the ground. Work has begun on ASTHROS (short for Astrophysics Stratospheric Telescope for High Spectral Resolution Observations at Submillimeter-wavelengths), a new mission that will carry a cutting-edge 8.4-foot te...
This image, taken on July 24, 1969, shows the Apollo 11 command module and the Mobile Quarantine Facility (MQF) photographed aboard the USS Hornet, prime recovery ship for the historic first lunar landing mission. The Apollo 11 crew, Neil Armstrong, Michael Collins and Buzz Aldrin, are already in the MQF. The Apollo 11 crew splashed down at 12:49 p.m. EDT, J...
Faintly in the distance, Comet C/2020 F3 NEOWISE (Comet NEOWISE) streaked across the sky above the tree line of Lone Pine Lake, located on the Mount Whitney Trail in the Eastern Sierra Nevada Mountains in California. The comet next returns in 6,800 years. Visiting from the distant parts of our Solar System, NEOWISE is characterized by a glowing tail and is v...
NASA is developing technologies to send humans to the Red Planet. The agency is working on an inflatable heat shield that allows the large surface area to take up less space in a rocket than a rigid one. The technology could land spacecraft on any planet with an atmosphere. It would expand and inflate before it enters the Martian atmosphere to land cargo and...
On July 21, 1969, command and service module pilot Michael Collins photographed this close-up view of the docking target on the Apollo 11 Lunar Module from the Command Module. The image was captured during docking in lunar orbit as Mission Commander Neil Armstrong and lunar module pilot Buzz Aldrin returned from the lunar surface. Collins had remained in lun...
On July 20, 1969, two American astronauts made history by landing on the surface of another celestial body. This image is a close-up view of the plaque, which Apollo 11 Commander Neil Armstrong and lunar module pilot Buzz Aldrin left on the Moon in commemoration of the historic lunar landing mission. The plaque was attached to the ladder on the landing gear ...
On July 17, 1975, something momentous happened: two Cold War rivals met in space. When their respective spacecraft rendezvoused and docked, a new era of cooperative ventures in space began. For more than two decades, American astronauts and Russian cosmonauts have been regularly living and working together in Earth orbit, first in the Shuttle-Mir program, an...
