NASA’s DART asteroid mission is a rare opportunity for scientists

Before NASA’s planetary defense probe DART self-destructs by slamming into the asteroid Dimorphos next week, it will offer views of only the sixth asteroid we will have ever seen up close. Scientists are eager to get their hands on those images, as they admit that we know extremely little about the space rocks potentially threatening … Read more

What time will NASA’s DART spacecraft hit an asteroid on Sept. 26?

A NASA spacecraft will soon make history when it crashes into an asteroid in the world’s first planetary defense test. The Double Asteroid Redirection Test, or DART asteroid mission, will slam a spacecraft into the tiny moon of the asteroid Didymos on Monday, Sept. 26with the impact set at 7:14 pm EDT (2314 GMT). If … Read more

NASA’s Juno will perform close flyby of Jupiter’s icy moon Europa

This image of Jupiter’s moon Europa was taken by the JunoCam imager aboard NASA’s Juno spacecraft on Oct. 16, 2021, from a distance of about 51,000 miles (82,000 kilometers). Credit: Image data: NASA/JPL-Caltech/SwRI/MSSS / Image processing by Andrea Luck On Thursday, Sept. 29, at 2:36 am PDT (5:36 am EDT), NASA’s Juno spacecraft will come … Read more

NASA’s Juno probe will peer beneath the icy crust of Europa

On Sept. 29, NASA’s Juno probe will perform the closest flyby of Jupiter’s icy moon Europa in over 20 years as the spacecraft embarks on a mission to deep probe into Europa’s ice in search of pockets of liquid water. Europe contains a global ocean beneath a solid crust of ice, making this moon one … Read more

NASA’s SpaceX Crew-5 astronauts ready for a historic mission

SpaceX’s next Crew Dragon astronaut launch for NASA will see a new country represented in one of the sleek white spacesuits. Russia’s Anna Kikina will take a seat on SpaceX with two American astronauts and a Japanese astronaut on the mission. The foursome will fly to the International Space Station (ISS) no earlier than Oct. … Read more

Revealing spacecraft geometry effects on impact simulations for NASA’s DART mission

The same DART spacecraft impact can result in very different craters on Dimorphos depending on what the asteroid material is like. The crater on the left is the result if Dimorphos is composed of strong rocky material, while the much larger crater shown on the right could occur if the Dimorphos is made up of … Read more

NASA’s DART asteroid-impact mission will be a key test of planetary defense

When NASA’s Double Asteroid Redirection Test (DART) slams into the tiny asteroid Dimorphos, it will be our first attempt to demonstrate our ability to deflect dangerous incoming asteroids. For decades, scientists around the world have been scanning the skysearching for potentially hazardous asteroids in the vicinity of Earth. And as astronomers discover near-Earth asteroids in … Read more

NASA’s Perseverance rover investigates geologically rich Mars terrain — ScienceDaily

NASA’s Perseverance rover is well into its second science campaign, collecting rock-core samples from features within an area long considered by scientists to be a top prospect for finding signs of ancient microbial life on Mars. The rover has collected four samples from an ancient river delta in the Red Planet’s Jezero Crater since July … Read more

NASA’s Perseverance rover investigates geologically rich Mars terrain

NASA’s Perseverance rover puts its robotic arm to work around a rocky outcrop called “Skinner Ridge” in Mars’ Jezero Crater. Composed of multiple images, this mosaic shows layered sedimentary rocks in the face of a cliff in the delta, as well as one of the locations where the rover abraded a circular patch to analyze … Read more
