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 United Kingdom Space Agency, SWOT is the first satellite mission that will observe nearly all water on Earth’s surface, measuring the height of water in the planet’s lakes, rivers, reservoirs, and the ocean. SWOT is set to launch at 6:46 a.m. EST on Dec. 15, 2022.

双子星座7号和双子星座6A号终于相遇

双子星座7号和双子星座6A号终于相遇

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 as Orion and the International Space Station are helping NASA learn how to go to Mars, the Gemini program defined and tested the skills NASA would need to go to the Moon in the 1960s and 1970s. Gemini had four main goals: to test an astronaut’s ability to fly long-duration missions (up to two weeks in space); to understand how spacecraft could rendezvous and dock in orbit around…

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 by NASA’s Landing and Recovery team, U.S. Navy and Department of Defense partners aboard the USS Portland. Recovery personnel also spent time collecting detailed imagery of the spacecraft before beginning to pull the capsule into the USS Portland’s well deck. The ship will soon begin its trip back to U.S. Naval Base San Diego, where engineers will remove Orion from the ship in preparation for…

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 second). It also committed the spacecraft to a Dec. 11 splashdown, which will air live on NASA Television, our website, and the NASA app. Follow Orion’s journey by visiting the Artemis I blog.

In this illustration by Rick Giudice from August 1973, the Pioneer 10 spacecraft passes by the gas giant planet Jupiter. The spacecraft’s primary goal was to explore Jupiter, its satellites, its magnetic field, and trapped radiation belts. Pioneer 10 was the first satellite to pass through an asteroid belt and the first spacecraft to obtain detailed images of Jupiter and its moons. Between 1972 and 1974, the Deep Space Network ground stations tracked the Pioneer 10 for over 21,000 hours. Pioneer 10 fell silent on its 30-year anniversary in 2002. Learn more about the Pioneer missions.

On the 19th day of the Artemis I mission, Dec. 4, 2022, a camera mounted on the Orion spacecraft captured the Moon just in frame as Orion prepared for its return powered flyby on Dec. 5, when it passed approximately 79 miles above the lunar surface. Orion performed the return powered flyby burn at 11:43 a.m. EST, changing the velocity of the spacecraft by approximately 655 mph (961 feet per second). The return powered flyby is the last large maneuver of the mission, with only smaller trajectory corrections to target Earth remaining. Follow Orion’s journey by visiting the Artemis I blog.

哈勃望远镜发现发射星云双星团

Against a backdrop littered with tiny pinpricks of light glint a few, brighter stars. This whole collection is NGC 1858, an open star cluster in the northwest region of the Large Magellanic Cloud, a satellite galaxy of our Milky Way that boasts an abundance of star-forming regions. NGC 1858 is estimated to be around 10 million years old. Open clusters are a type of star cluster with loose gravitational attraction between the stars, which causes the cluster to be irregularly shaped and its stars to be spread out. NGC 1858 is also an emission nebula, which is a cloud of interstellar gas that has been ionized by ultraviolet wavelengths radiating off of nearby stars. The gas of the nebula emits its own light at visible…
