Dawn mission managers await NASA decision on spacecraft’s future

17 June 2017 Stephen Clark

The future of NASA’s Dawn spacecraft, running low on hydrazine fuel and now flying around the dwarf planet Ceres without the help of internal pointing wheels, will be decided in the coming weeks by top space agency managers.

Earlier launch of NASA’s Psyche mission touted as cost-saving measure

26 May 2017 Stephen Clark

A NASA spacecraft set to explore a metallic asteroid for the first time will launch in 2022, a year earlier than originally planned, and reach its destination in 2026, four years ahead of schedule, giving ground teams a shorter wait for the mission’s scientific payoff and shaving $100 million off the project’s total cost, officials said Wednesday.

Gravitational wave testbed repurposed as comet dust detector

26 April 2017 Stephen Clark

In the final months of Europe’s LISA Pathfinder mission, scientists have found an unexpected use for the trailblazing testbed for a future gravitational wave observatory by tracking the tiny dings made by microscopic particles that strike the spacecraft in deep space, exploiting the impacts to learn about the population of dust grains cast off by comets and asteroids across the solar system.

NASA’s OSIRIS-REx probe moonlights as asteroid sleuth

1 February 2017 Stephen Clark

On course to collect specimens from asteroid Bennu after its launch last year, NASA’s OSIRIS-REx spacecraft will search this month for objects sharing an orbit with Earth, a bonus science opportunity to locate possible fragments of the primordial building blocks that formed our home planet.

Future of asteroid deflection mission to be decided soon

20 January 2017 Stephen Clark

Decisions on the future of a joint robotic mission between NASA and the European Space Agency to demonstrate the ability to deflect an asteroid on a collision course with Earth have been put off until later this year after European governments declined to fully fund their part of the project in December.

Two asteroid missions get nod from NASA

11 January 2017 Stephen Clark

NASA has selected two robotic missions to visit asteroids in the early 2020s from a field of proposed interplanetary probes, approving projects to explore a metallic relic from the early solar system and a half-dozen so-called Trojan objects left over from the formation of the outer planets.

NASA’s NEOWISE mission spies one comet, maybe two

30 December 2016 Stephen Clark

NASA’s NEOWISE mission has recently discovered some celestial objects traveling through our neighborhood, including one on the blurry line between asteroid and comet. Another — definitely a comet — might be seen with binoculars through next week.

Hunt for water at Ceres goes underground

23 December 2016 Stephen Clark

NASA’s Dawn spacecraft has continued its survey of the dwarf planet Ceres this year, discovering rock-bound ice hidden just beneath the airless world’s rugged surface and a handful of icy outcrops inside craters in the northern hemisphere, raising hopes that Ceres could have once held a buried habitable ocean of liquid water.

Take a walk around NASA’s asteroid sample probe

26 August 2016 Stephen Clark

We take a walk around NASA’s OSIRIS-REx spacecraft before it was loaded into the nose cone of the Atlas 5 rocket that will launch it on 8 September.

A unique project to track two asteroids for Asteroid Day 2016

29 June 2016 Astronomy Now

Las Cumbres Observatory have partnered with Asteroid Day 2016 and Universe Awareness to create a website which allows you to use a global network of robotic telescopes to take pictures of two asteroids — 2002 KL6 and 2010 NY65 — currently passing close to Earth. On the website you can join the international campaign to study and raise awareness about asteroids.
