Hawaii’s big island and its two major volcanoes Mauna Kea and Mauna Loa rest under a partly cloudy sky on Feb. 8, 2022, in this view from the International Space Station. Mauna Loa, the world’s largest active volcano had been quiet for nearly 40 years. However, in 2022, the volcano began to stir, showing increased numbers of small earthquakes and subtl...
By taking a closer look at one of Webb’s first images, the iconic Cosmic Cliffs, scientists have found dozens of energetic jets and outflows from young stars previously hidden by dust clouds. The discovery marks the beginning of a new era of investigating how stars like our Sun form, and how the radiation from nearby massive stars might affect the developmen...
On Dec. 18, 2022, InSight did not respond to communications from Earth. As expected, the lander’s power has been declining for months, and it’s assumed InSight may have reached its end of operations. NASA will declare the mission over when InSight misses two consecutive communication sessions with the spacecraft orbiting Mars, part of the Mars Relay Network ...
NASA is taking a leading role to help integrate new types of Advanced Air Mobility aircraft like air taxis and delivery drones into the sky, helping emerging markets to safely develop an air transportation system that moves people and cargo between places previously not served or underserved by aviation. NASA is working with private sector developers of elec...
A portion of the open cluster NGC 6530 appears as a roiling wall of smoke studded with stars in this image from the NASA/ESA Hubble Space Telescope. NGC 6530 is a collection of several thousand stars lying around 4,350 light-years from Earth in the constellation Sagittarius. The cluster is set within the larger Lagoon Nebula, a gigantic interstellar cloud of...
Against an inky black backdrop, the blue swirls of spiral galaxy NGC 6956 stand out radiantly. NGC 6956 is a barred spiral galaxy, a common type of spiral galaxy with a bar-shaped structure of stars in its center. This galaxy exists 214 million light-years away in the constellation Delphinus. Scientists used NASA’s Hubble Space Telescope to image NGC 6956 to...
A SpaceX Falcon 9 rocket with the Surface Water and Ocean Topography (SWOT) spacecraft onboard is seen as it rolls out to the pad, Tuesday, Dec. 13, 2022, at Space Launch Complex 4E at Vandenberg Space Force Base in California. Jointly developed by NASA and Centre National D’Etudes Spatiales, with contributions from the Canadian Space Agency and the Un...
In this photo from Dec. 15, 1965, the Gemini-VII spacecraft is seen from the Gemini-VI-A spacecraft during their rendezvous mission in space. The two spacecraft are approximately 43 feet apart. Astronauts Jim Lovell and Frank Borman launched on Gemini-VII on Dec. 4, 1965, and eventually spent two weeks in orbit, the longest-duration flight at that time. Just...
At 12:40 p.m. EST, Dec. 11, 2022, the Orion spacecraft for the Artemis I mission splashed down in the Pacific Ocean after a 25.5-day mission to the Moon. Flight controllers in mission control at NASA’s Johnson Space Center in Houston spent about two hours performing tests in open water to gather additional data about the spacecraft. Orion was then recovered ...
On flight day 20 of the Artemis I mission, Dec. 5, 2022, Orion captured the Moon on the day of return powered flyby, the final major engine maneuver of the flight test. The burn, which used the spacecraft’s main engine on the European-built service module, lasted 3 minutes, 27 seconds, and changed the velocity of the spacecraft by about 655 mph (961 feet per...
