Pressure vessels built by SpaceX to test its Crew Dragon designs are going through structural testing, so engineers can analyze the spacecraft’s ability to withstand the harsh conditions of launch and spaceflight. A pressure vessel is the area of the spacecraft where astronauts will sit during their ride to the International Space Station. To source
This raw, unprocessed image was taken by NASA’s Cassini spacecraft on May 20, 2012. The camera was pointing toward the Saturn moon Tethys at approximately 81,580 miles (131,290 kilometers) away. Credit: NASA/JPL/Space Science Institute Although Saturn’s moon Tethys appears bland and neutral from space, it contains a number of features of interest. A large impact […]
This raw image of Saturn’s icy moon Rhea was taken on March 10, 2013 by NASA’s Cassini spacecraft, and received on Earth March 10, 2013. The camera was pointing toward Rhea at approximately 174,181 miles (280,317 kilometers) away.

Credit: NASA NASA’s Juno spacecraft will reach Jupiter Monday (July 4) after a five-year journey through deep space. The probe will study the structure and evolution of the solar system’s largest planet from orbit, taking measurements for more than a year despite […]
This photo shows NASA’s Mars rover Curiosity at a location called “Windjana,” where the rover found rocks containing manganese-oxide minerals, which require abundant water and strongly oxidizing conditions to form Credit: NASA/JPL-Caltech/MSSS Ancient Mars was even more Earth-like than scientists had thought, a new study suggests. NASA’s Curiosity rover has detected high concentrations of manganese […]

The second and final qualification motor (QM-2) test for the Space Launch System’s booster is seen, Tuesday, June 28, 2016, at Orbital ATK Propulsion Systems test facilities in Promontory, Utah. During the Space Launch System flight the boosters will provide more than 75 percent of the thrust needed to escape the gravitational pull of the […]
Thousands of onlookers gawked as a column of flame exploded across the desert floor outside Promontory, Utah, today (June 28) during a test of the engine that will help power NASA’s next-generation rocket. Lying horizontally, the engine for NASA’s Space Launch System (SLS) rocket booster released a massive blast of flame and a wall of […]
