NASA's team that will conduct the first U.S. mission to collect samples from an asteroid has been given the go-ahead to begin building the spacecraft, flight instruments and ground system, and launch support facilities.
The NASA/ESA Hubble Space Telescope has photographed the never-before-seen break-up of an asteroid, which has fragmented into as many as ten smaller pieces. Although fragile comet nuclei have been seen to fall apart as they approach the Sun, nothing like the breakup of this asteroid, P/2013 R3, has ever been observed before in the asteroid belt.
ESO’s New Technology Telescope (NTT) has been used to find the first evidence that asteroids can have a highly varied internal structure. By making exquisitely precise measurements astronomers have found that different parts of the asteroid Itokawa have different densities.
Several sources confirm that the first discovered asteroid in 2014, designated 2014 AA, entered Earth’s atmosphere late Jan. 1 (Jan. 2 Universal time) over the mid-Atlantic Ocean.
For nearly as long as astronomers have been able to observe asteroids, a question has gone unanswered: Why do the surfaces of most asteroids appear redder than meteorites — the remnants of asteroids that have crashed to Earth?
Astronomers have found the shattered remains of an asteroid that contained huge amounts of water orbiting an exhausted star, or white dwarf. This suggests that the star GD 61 and its planetary system – located about 150 light years away and at the end of its life – had the potential to contain Earth-like exoplanets, they say.
Tantalized by images from NASA's Hubble Space Telescope and ground-based data, scientists thought the giant asteroid Vesta deserved a closer look. They got a chance to do that in 2011 and 2012, when NASA's Dawn spacecraft orbited the giant asteroid, and they were able to check earlier conclusions.
An atlas of the asteroid, Vesta, created from images taken during the Dawn Mission’s Low Altitude Mapping Orbit (LAMO), is now accessible for the public to explore online. The set of maps has been created from mosaics of 10 000 images from Dawn’s framing camera (FC) instrument, taken at an average altitude of about 210 kilometres.
This image shows the potentially hazardous near-Earth object 1998 KN3 as it zips past a cloud of dense gas and dust near the Orion nebula.
NASA has released new photos and video animations depicting the agency's planned mission to find, capture, redirect, and study a near-Earth asteroid. The images depict crew operations including the Orion spacecraft's trip to and rendezvous with the relocated asteroid, as well as astronauts maneuvering through a spacewalk to collect samples from the asteroid.
On May 31, 2013, asteroid 1998 QE2 will sail serenely past Earth, getting no closer than about 3.6 million miles (5.8 million kilometers), or about 15 times the distance between Earth and the moon.
NASA's first mission to sample an asteroid is moving ahead into development and testing in preparation for its launch in 2016.
In a key geological moment about 66 million years ago, an enigmatic something killed off almost all the dinosaurs and some 70 percent of all other species living on Earth.
ESA’s planning to crash a spacecraft into an asteroid called Didymos, to, well, see what happens.
Two US scientists say they've come up with a method of deflecting or destroying asteroids that could have dealt with last Friday's in less than an hour.
The scientific community is aflutter after reports, images, and video of a massive meteor explosion in Russia clogged the Internet early Friday morning.
An asteroid the size of a small office block is due to whizz past Earth on Friday, traveling at over 28,000 miles per hour.
A few years ago, if a company had stepped up and said it planned to send unmanned spacecraft to explore the possibility of mining asteroids in near earth orbit, quite a number of us probably would have politely chuckled.
NASA scientists are now certain that the asteroid Apophis won't, as feared, hit the Earth during a flyby in 2036.
The massive asteroid Apophis shot past Earth last night, on a trajectory that will bring it even closer during its next flyby in 2029.
