Construction to begin on NASA spacecraft set to visit asteroid in 2018

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.

Hubble witnesses an asteroid mysteriously disintegrating

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.

The Anatomy of an Asteroid

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.

First 2014 asteroid discovered

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.

Asteroids' close encounters with Mars

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?

Watery asteroid discovered in dying star points to habitable exoplanets

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.

Dawn reality checks telescope studies of asteroids

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.

Taking a virtual tour of the Vesta asteroid

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.

Asteroid zips By Orion Nebula

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 releases new asteroid mission images

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.

Asteroid 1998 QE2 to sail past Earth 9x larger than cruise ship

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 asteroid sample return mission moves forward

NASA's first mission to sample an asteroid is moving ahead into development and testing in preparation for its launch in 2016.

Claim: Comet, not an asteroid, killed the dinosaurs

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 picks target asteroid for spaceship crash

ESA’s planning to crash a spacecraft into an asteroid called Didymos, to, well, see what happens.

Sun's energy could be used to zap dangerous asteroids

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.

NASA: Meteor explosion in Russia had nothing to do with asteroid flyby

The scientific community is aflutter after reports, images, and video of a massive meteor explosion in Russia clogged the Internet early Friday morning.

Asteroid to buzz Earth on Friday

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.

Deep Space Industries wants FireFly ships to mine asteroids

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.

Earth safe from 2026 asteroid strike, says NASA

NASA scientists are now certain that the asteroid Apophis won't, as feared, hit the Earth during a flyby in 2036.

Asteroid Apophis passes safely past Earth

The massive asteroid Apophis shot past Earth last night, on a trajectory that will bring it even closer during its next flyby in 2029.
