NASA's Curiosity Mars rover used its Mast Camera, or Mastcam, to capture this scene around a drill hole named "Edinburgh." The images used to create the scene were taken on March 22 and 23, 2020, which were the 2,711th and 2,712th Martian days, or sols, of the mission. The scene was captured while Curiosity was parked on top of a feature called the "Greenheugh Pediment." Looming above in the background is the top of Mount Sharp, the 3-mile-tall (5-kilometer-tall) mountain that Curiosity has been ascending since 2014. The color balance of the scene was processed to reflect the way it would look to the human eye under daytime lighting on Earth. https://photojournal.jpl.nasa.gov/catalog/PIA25046

NASA's Curiosity Mars rover used its Mast Camera, or Mastcam, to capture this view of Earth setting while Phobos, one of Mars' two moons, is rising. It's the first time an image of the two celestial bodies have been captured together from the surface of Mars. The image is a composite of five short exposures and 12 long exposures all taken on Sept. 5, 2024, the 4,295th Martian day, or sol, of Curiosity's mission. An inset in the image shows Phobos on the left and Earth on the right. From the rover's perspective, the inset area would be about half the width of a thumb held at arm's length. The image shows the sky over Texoli, a butte on lower Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain that Curiosity has been ascending since 2014. https://photojournal.jpl.nasa.gov/catalog/PIA26362

CAPE CANAVERAL, Fla. – Former NASA shuttle astronaut and space explorer Shannon Lucid was inducted into the U.S. Astronaut Hall of Fame class of 2014 during a ceremony inside the Space Shuttle Atlantis attraction at NASA’s Kennedy Space Center Visitor Complex in Florida. Lucid is the only American woman to serve aboard the Russian Space Station Mir and was the first woman to join a U.S. class of astronauts. She held the record until 2007 for the most flight hours in orbit by a female astronaut, 223 days. The 2014 inductees were selected by a committee of Hall of Fame astronauts, former NASA officials, flight directors, historians and journalists. The process is administered by the Astronaut Scholarship Foundation. To be eligible, an astronaut must have made his or her first flight at least 17 years before the induction. Candidates must be a U.S. citizen and a NASA-trained commander, pilot or mission specialist who has orbited the earth at least once. Including Lucid and Ross, 87 astronauts have been inducted into the AHOF. Photo credit: NASA/Kim Shiflett

CAPE CANAVERAL, Fla. -- Inside the Launch Equipment Test Facility at NASA’s Kennedy Space in Florida, a second firing of the escape hold down post has occurred during a pyrotechnic bolt test on the Orion ground test vehicle. Lockheed Martin performed tests over a series of days on the explosive bolts that separate Orion from the launch abort system. Data was collected on the effect of shock waves on Orion during the explosive bolt separation. Orion is the exploration spacecraft designed to carry crews to space beyond low Earth orbit. It will provide emergency abort capability, sustain the crew during the space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of the Orion is scheduled to launch in 2014 atop a Delta IV rocket and in 2017 on a Space Launch System rocket. For more information, visit http://www.nasa.gov/orion.

Strong north winds often blow in summer, churning up dust from the entire length of the desert surfaces of the Tigris and Euphrates valleys (top left). Dust partly obscures the hundreds of kilometers of Iraq’s light-green agricultural lands along these rivers (left). A line of thunderstorms is being set off by the Zagros Mountains of Iran (right), with the setting sun casting long shadows from the thunderheads. Space station crews see sixteen sunrises and sunsets every day from low Earth orbit. Here the crew captured dusk in a darkening Iranian landscape (right).
