Where are all the large impact craters on Ceres?

Where are all the large impact craters on Ceres? Astronomers agree with you — most of the rocks in our asteroid belt look pretty careworn.So they expected that when NASA’s Dawn spacecraft got to Ceres, they would see similarly many large impact craters marring the dwarf planet’s surface, just like every other rocky thing in our entire solar system.

Launch of NASA’s asteroid sample-return mission goes off without a hitch

Launch of NASA’s asteroid sample-return mission goes off without a hitch The asteroid Bennu is about to have a visitor — NASA’s OSIRIS-REx spacecraft lifted off from Cape Canaveral, Florida as planned yesterday evening.There are, of course, plenty of samples of asteroids on Earth — they literally fall out of the sky every day.

NASA and FEMA hold exercise to simulate unavoidable asteroid impact

NASA and FEMA hold exercise to simulate unavoidable asteroid impact Technology gives us a shot at stopping the worst-case scenario, something that experts from NASA and FEMA recently got together to simulate.The exercise included representatives from NASA, FEMA, NASA’s Jet Propulsion Laboratory, the Department of Energy’s National Laboratories, the US Air Force, and the California Governor’s Office of Emergency Services.

Scientists push for 2020 launch of asteroid deflection test

Scientists push for 2020 launch of asteroid deflection test The ESA and NASA are pushing for a 2020 mission to test technologies that could help us deflect an object before it smacks into Earth.The joint European-US Asteroid Impact and Deflection Assessment (AIDA) is still in the planning stages, but it could launch in 2020.

NASA releases new image of mysterious bright spots on dwarf planet Ceres

NASA releases new image of mysterious bright spots on dwarf planet Ceres Depending on how you want to define a planet, Ceres could almost be a fit.Most recently, Dawn moved to an altitude of 960 miles (1480 kilometers), which is how the latest images of the bright spots were captured.

NASA plans two new Discovery Program asteroid intercept missions

NASA plans two new Discovery Program asteroid intercept missions The first mission to launch will be dubbed Lucy, a probe built by Lockheed-Martin to study Jupiter’s so-called Trojan asteroids.The plan is to launch Lucy in October 2021 for an efficient transfer to Jupiter’s orbit.

Debris from ancient asteroid explosion still peppering our planet

Debris from ancient asteroid explosion still peppering our planet At a time when terrestrial plant life was just beginning to take hold here on Earth some 466 million years ago, a massive asteroid collision happened someplace nearby.The University of Chicago team led by cosmochemist Philipp Heck were able to find ancient meteorite fragments from before the chondrite-forming event.

A robotic NASA mission could help us mine asteroids in the future

A robotic NASA mission could help us mine asteroids in the future Elkins-Tanton isn't the only one who thinks the Psyche mission could be great for asteroid mining in the future.Chris Lewicki, the CEO of the asteroid mining company Planetary Resources, also thinks that the Psyche mission could help gather data that will allow his company to explore and exploit asteroids in the future.

Space rocks, a space telescope and a space station: this week in space

Space rocks, a space telescope and a space station: this week in space Cosmochemist Philipp Heck dissolved a rock in strong acid to liberate the tiny, crystalline bits of ancient asteroid within.They’ve been collaborating with the ESA to use the Hubble Space Telescope to measure the expansion of the Universe.

Asteroid discovered hours before it passes between Earth and moon

Asteroid discovered hours before it passes between Earth and moon While you were sleeping last night, an asteroid passed close to Earth—very close.That’s closer than the orbit of the moon, which is 238,000 miles away.

Earth's crust bears the scars of bombardment by shattered cores of failed planets

Earth's crust bears the scars of bombardment by shattered cores of failed planets William Bottke presented details from his ongoing research on the Earth’s history of getting smashed with debris.By “elsewhere,” he means from a population of failed planets whose cores never got the chance to become fully formed.
