A SpaceX Dragon cargo spacecraft lifted off on its way to the International Space Station after launching at 11:50 p.m. EST Friday, March 6. The spacecraft launched on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida and arrived at the orbital outpost on Monday, March 9. Dragon joins three other spacecraft currently at the station. NASA astronauts Jessica Meir and Andrew Morgan grappled Dragon, which is scheduled to remain at the space station until April 9, when the spacecraft will return to Earth with research and cargo. ​Dragon was successfully berthed to the Node 2 Nadir port.

The barred spiral galaxy NGC 3887, seen here as viewed by the Wide Field Camera 3 aboard the NASA/ESA Hubble Space Telescope, lies over 60 million light-years away from us in the southern constellation of Crater (the Cup). It was discovered on Dec. 31, 1785, by astronomer William Herschel. Its orientation to us, while not exactly face-on, allows us to see NGC 3887’s spiral arms and central bulge in detail, making it an ideal target for studying a spiral galaxy’s winding arms and the stars within them. The very existence of spiral arms was for a long time a problem for astronomers. The arms emanate from a spinning core and should therefore become wound up ever more tightly, causing them to eventually disappear after a…

See Jupiter’s Great Red Spot as you’ve never seen it before in this work of art. Artist Mik Petter created this unique, digital artwork using data from the JunoCam imager on NASA’s Juno spacecraft. The art form, known as fractals, uses mathematical formulas to create art with an infinite variety of form, detail, color and light. The tumultuous atmospheric zones in and around the Great Red Spot are highlighted by the author’s use of colorful fractals. Vibrant colors of various tints and hues, combined with the almost organic-seeming shapes, make this image seem to be a colorized and crowded petri dish of microorganisms, or a close-up view of microscopic and wildly-painted seashells. The original JunoCam image was taken on July 10, 2017, at 10:10 p.m….

NASA’s Orion spacecraft, a critical part of the agency’s Artemis I mission, is nearing the end of a three-month testing campaign at the agency’s Plum Brook Station in Sandusky, Ohio. During the testing, the craft was subjected to the extreme temperatures and electromagnetic environment it will experience in its upcoming test mission to the Moon.

On March 3, 1915, Congress created the National Advisory Committee for Aeronautics (NACA), the organization from which NASA was created in 1958. NACA research led to advances in aeronautics that helped the Allies win World War II, spawned a world-leading civil aviation manufacturing industry, propelled supersonic flight, supported national security during the Cold War and laid the foundation for modern air travel and the space age. This group photo was taken on steps of Langley Research Building on Nov. 5, 1928. In the front row are, left to right: E.A. Meyers, Elton Miller, Amelia Earhart, Henry Reid, and Lt. Col. Jacob W.S. Wuest. In the back row are, left to right: Carlton Kemper, Raymond Sharp, Thomas Carroll, (unknown person behind A.E.), and Fred Weick. During…

Tracy Drain’s job is to literally “go where no one has gone before.” Drain is systems engineer at NASA’s Jet Propulsion Lab. In this cellphone image, she stands with one of her childhood inspirations … Nichelle Nichols, Star Trek’s Lt. Uhura. The image was taken when Nichols visited JPL on Aug. 15, 2016, during the time when Tracy was the deputy chief engineer for the Juno mission to Jupiter. So what exactly does a systems engineer do? This is what Drain does in her own words: “When you think about a spacecraft and all the different parts that are necessary to make a spacecraft work, there are engineers who focus on designing/build each of those specific areas (like telecommunications, thermal, attitude control, etc.). But a…

土星IB的首飞

土星IB的首飞

On Feb. 26, 1966, AS-201, the first Saturn IB rocket, lifted off from NASA’s Kennedy Space Center. Designed and developed by NASA’s Marshall Space Flight Center, the AS-201 mission was an uncrewed suborbital flight to test the Saturn IB and the Apollo Command and Service modules. The objectives of the flight were to verify the structural integrity, launch loads, stage separation and operation of subsystems of the Saturn 1B, and evaluate the Apollo spacecraft subsystems, heatshield and mission support facilities. Today, NASA aims to return to the Moon by 2024 with our Artemis Program, which will land American astronauts, including the first woman and the next man, on the Moon. Through the agency’s Artemis lunar exploration program, we will use innovative new technologies and systems…

Gullies on Mars form during the winter, fluidized by carbon dioxide frost, and scientists monitor sites on the planet for activity throughout the year. In this mid-winter scene, a Martian gully is almost completely frosted over the pole-facing slope within the shadow. The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. (The original image scale is 50.5 centimeters [19.9 inches] per pixel [with 2 x 2 binning]; objects on the order of 152 centimeters [59.8 inches] across are resolved.) North is up. NASA’s Mars Reconnaissance Orbiter, launched August 12, 2005, continuously monitors the Red Planet from orbit and continues in its mission to search for evidence that water persisted on the surface of Mars for a long period of…
