NASA's intrepid Voyager twins, Voyager 1 and Voyager 2, launched in 1977, continue their unprecedented explorations of interstellar space. But as they reach farther distances from Earth-more than 15 billion miles for Voyager 1 and 12 billion for Voyager 2-keeping them operational requires strategic forethought. One pressing concern relates to the gradual buildup of propellant residue in t

At some point, statistically speaking, a large asteroid will impact Earth. Whether that’s tomorrow, in ten years, or a problem for our ancestors, ESA is getting prepared.

As part of the world’s first test of asteroid deflection, ESA’s Hera mission will perform a detailed post-impact survey of Dimorphos – the 160-metre asteroid struck, and successfully deflected, by NASA’s DART spacecraft.

Hera will soon study the aftermath. Launching in October 2024, Hera will turn this grand-scale experiment into a well-understood and hopefully repeatable planetary defence technique.

But before Hera and its two CubeSats fly, they’re rigorously tested at ESA’s ESTEC test

Earth planning date: Wednesday, October 18, 2023: The target 'Sequoia' has been successfully drilled! The image today is one of my favourites - the shadow of the rover mast, and the perfectly drilled target in the background... it doesn't get much better than that! Curiosity stays in place for a little while longer for CheMin analysis of the drilled material, and no drive meant we had more power

Astronomers at ARC are one step closer to understanding an enduring solar mystery by capturing the most detailed representations to date of the magnetic field of the 'quiet Sun' - and discovering something unexpected in the process. The researchers from the Astrophysics Research Centre (ARC) at the School of Mathematics and Physics at Queen's have collected groundbreaking data with the US

In a paper published in Science, a global team led by Macquarie University's Dr Stuart Ryder and Swinburne University of Technology's Associate Professor Ryan Shannon, report on their discovery of the most ancient and distant fast radio burst located to date, about eight billion years old. The discovery smashes the team's previous record by 50 per cent. It confirms that fast radio bursts (

NASA recently built and tested an additively-manufactured - or 3D printed - rocket engine nozzle made of aluminum, making it lighter than conventional nozzles and setting the course for deep space flights that can carry more payloads. Under the agency's Announcement of Collaborative Opportunity, engineers from NASA's Marshall Space Flight Center in Huntsville, Alabama, partnered with Eleme

NASA's Lucy spacecraft is preparing for its first close-up look at an asteroid. On Nov. 1, it will fly by asteroid Dinkinesh and test its instruments in preparation for visits in the next decade to multiple Trojan asteroids that circle the Sun in the same orbit as Jupiter. Dinkinesh, less than half a mile, or 1 kilometer, wide, circles the Sun in the main belt of asteroids located between
