For its final trick, Chandrayaan-3 brings its propulsion module to Earth orbit
Thursday, 07 December 2023 18:33
On August 23, ISRO's Vikram lander detached from its propulsion module and made a soft landing near the moon's south pole region. The lander then deployed its Pragyan rover, and for two weeks the endearing little solar-powered rover performed marvelously, detecting water ice and characterizing the makeup of the lunar regolith before succumbing to the darkness and cold of the lunar night.
But since the rover mission ended, the propulsion module that brought it to the moon has made a detour, performing a series of complex maneuvers that took it from a tight lunar orbit back to Earth orbit.
Psyche gamma-ray instrument hums to life, marking next generation for space exploration
Thursday, 07 December 2023 18:22
Set 6.5 feet (2 meters) away from NASA's Psyche spacecraft on the tip of a boom, the mission's gamma-ray spectrometer (GRS) hummed to life on Nov. 6 for the first time since launch in mid-October.
Communicating with a relativistic spacecraft gets pretty weird
Thursday, 07 December 2023 17:17
Someday, in the not-too-distant future, humans may send robotic probes to explore nearby star systems. These robot explorers will likely take the form of lightsails and wafercraft (a la Breakthrough Starshot) that will rely on directed energy (lasers) to accelerate to relativistic speeds—aka a fraction of the speed of light. With that kind of velocity, lightsails and wafercraft could make the journey across interstellar space in a matter of decades instead of centuries (or longer!) Given time, these missions could serve as pathfinders for more ambitious exploration programs involving astronauts.
Of course, any talk of interstellar travel must consider the massive technical challenges this entails. In a recent paper posted to the arXiv preprint server, a team of engineers and astrophysicists considered the effects that relativistic space travel will have on communications.

Minding the gap on tropical forest carbon
Thursday, 07 December 2023 07:00
Tropical forests are clearly critical to Earth’s climate system, but understanding exactly how much carbon they absorb from the atmosphere, store and release is tricky to calculate, not least because measuring and reporting methods vary. With these measurements paramount for nations assessing the action they are taking to combat the climate crisis, new research shows how differences in estimates of carbon flux associated with human activity can be reconciled.
To see the Universe in aluminium
Thursday, 07 December 2023 06:55
Lightweight but robust, aluminium is the single most versatile space material. A new ESA project extends this versatility still further, by investigating the production of big aluminium mirrors for space-based astronomy. Applying a novel technique, the team joined together multiple aluminium segments to form a single mirror. The resulting surface had to be optically perfect however, with no trace left of joins in the combined metal.
