Two NASA spacecraft — the OSIRIS-REx asteroid sample return mission and the New Horizons probe at the edge of the solar system — have captured their first looks at their targets as they approach a pair of primordial relics for the first time.

Engineers still hopeful Mars rover will wake up after dust storm

August 22, 2018 William Harwood

Flight controllers have not heard from NASA’s Opportunity Mars rover since June 10 when an increasingly severe global dust storm blocked out the sun, preventing its solar arrays from recharging the robot’s batteries. But the dust storm is finally abating and engineers are hopeful the long-lived rover will wake up and phone home in the next few weeks.

First milestones accomplished on NASA’s newly-launched Parker Solar Probe

August 19, 2018 Stephen Clark

Space missions dispatched into the solar system often have journeys lasting years before reaching a scientific payoff, but NASA’s Parker Solar Probe launched last weekend on a speedy departure from planet Earth is already getting ready to sweep closer to the sun than any spacecraft in history during a flyby later this year.

Hayabusa 2 probe gets a closer look at asteroid amid landing preps

August 15, 2018 Stephen Clark

The Japanese Hayabusa 2 spacecraft dropped within a half-mile of asteroid Ryugu last week, probing its gravity field ahead of key decisions in the coming days to settle on a target site for the robotic mission’s first sample collection attempt, and the best touchdown location for a European lander stowed on the mothership.

Scientists thrilled with closer views of Ceres’ famous salty crater

July 3, 2018 Stephen Clark

Fresh pictures from NASA’s Dawn spacecraft have provided the sharpest glimpse yet of the bright salt deposits discovered inside a crater on Ceres, the largest object in the asteroid belt.

Arianespace aims for busy second half of 2018

July 3, 2018 Stephen Clark

Europe’s first mission to Mercury, a quartet of Galileo navigation spacecraft, the world’s first global winds observatory, and a new European weather satellite have arrived at an equatorial launch base in French Guiana in preparation for launches in the coming months.

Japanese spacecraft reaches asteroid after three-and-a-half-year journey

June 28, 2018 Stephen Clark

Japan’s robotic Hayabusa 2 spacecraft arrived Wednesday at asteroid Ryugu, a diamond-shaped object more than a half-mile wide where the probe will attempt a brief landing later this year to collect rock specimens for return to Earth.

Growing dust storm encircles Mars, rover remains silent

June 21, 2018 Stephen Clark

The effects of a global dust storm on Mars have been observed by NASA’s plutonium-powered Curiosity rover, which continues its scientific campaign as the thick veil of dust continues starving the aging Opportunity rover of solar energy on the other side of the planet.

Asteroid Ryugu revealed by approaching Japanese spacecraft

June 20, 2018 Stephen Clark

In the final days of a three-and-a-half year pursuit, Japan’s Hayabusa 2 sample return spacecraft is beaming back clearer images of asteroid Ryugu, an unexplored object that scientists say resembles a spinning top or dumpling nearly 180 million miles from Earth.

Dawn spacecraft flying low over Ceres

June 15, 2018 Stephen Clark

In the closing months of a nearly 11-year mission, NASA’s Dawn spacecraft has arrived in its final orbit around the dwarf planet Ceres and is obtaining the sharpest views yet of the king of the asteroid belt.
