When a planet’s orbit brings it between Earth and a distant star, it’s more than just a cosmic game of hide and seek. It’s an opportunity for NASA to improve its understanding of that planet’s atmosphere and rings. Planetary scientists call it a stellar occultation and that’s exactly what happened with Uranus on April 7. … Read more
Have we ever been to Uranus? The answer is simple, yes, but only once. The Voyager II spacecraft flew by the planet Uranus back in 1986, during a golden era when the Voyager spacecraft explored all four giant planets of our solar system. It revealed an extreme world, a planet that had been bowled over … Read more
NASA is bringing the world of planetary defense to the public with its new documentary, “Planetary Defenders.” What would humanity do if an asteroid were headed for Earth? The documentary takes viewers inside the real-life efforts of scientists and engineers working to detect, track, and mitigate potential asteroid threats. Featuring firsthand accounts from experts on … Read more
How can I see the northern lights? To see the northern lights, you need to be in the right place at the right time. Auroras are the result of charged particles and magnetism from the Sun called space weather dancing with the Earth’s magnetic field. And they happen far above the clouds. So you need … Read more
Researchers analyzing pulverized rock onboard NASA’s Curiosity rover have found the largest organic compounds on the Red Planet to date. The finding, published Monday in the Proceedings of the National Academy of Sciences, suggests prebiotic chemistry may have advanced further on Mars than previously observed. Scientists probed an existing rock sample inside Curiosity’s Sample Analysis … Read more
Although NASA’s Lucy spacecraft’s upcoming encounter with the asteroid Donaldjohanson is primarily a mission rehearsal for later asteroid encounters, a new paper suggests that this small, main belt asteroid may have some surprises of its own. New modeling indicates that Donaldjohanson may have been formed about 150 million years ago when a larger parent asteroid … Read more
NASA has selected Firefly Aerospace Inc. of Cedar Park, Texas, to provide the launch service for the agency’s Investigation of Convective Updrafts (INCUS) mission, which aims to understand why, when, and where tropical convective storms form, and why some storms produce extreme weather. The mission will launch on the company’s Alpha rocket from NASA’s Wallops … Read more
NASA has selected eight participating scientists to join its Lucy mission to the Jupiter Trojan asteroids. These asteroids are remnants of our early solar system trapped on stable orbits associated with — but not close to — the planet Jupiter. NASA’s Lucy in the L4 Trojans Participating Scientist Program supports scientists to carry out new investigations … Read more
That’s a great question. And it’s a question that NASA will seek to answer with the Europa Clipper spacecraft. Europa is a moon of Jupiter. It’s about the same size as Earth’s Moon, but its surface looks very different. The surface of Europa is covered with a layer of ice, and below that ice, we … Read more
NASA has selected SpaceX of Starbase, Texas, to provide launch services for the Near-Earth Object (NEO) Surveyor mission, which will detect and observe asteroids and comets that could potentially pose an impact threat to Earth. The firm fixed price launch service task order is being awarded under the indefinite delivery/indefinite quantity NASA Launch Services II … Read more
