The 14th ESA/JRC International Summer School on GNSS, organized by the European Space Agency (ESA) and the Joint Research Centre (JRC), took place in July in Kiruna, Sweden. The Summer School, sponsored this year by GMV, trains the next generations of scientists and engineers to master space-related applications.

Southwest Research Institute developed an algorithm to remotely update and repair spacecraft software using less time and data than conventional techniques. The tool not only improves the overall efficiency of satellite software transmissions but also can recover data from failed over-the-air updates and malicious cyberattacks.

Many as-yet-undiscovered interstellar objects exist throughout our Milky Way Galaxy: comets and asteroids that have been ejected from their home star systems. Some of these objects pass through our Solar System, bringing valuable information about how planetary systems form and evolve. Currently, only two such interstellar visitors have been discovered: 1I/?Oumuamua and comet 2I/Borisov. Rubin's Monster waves as tall as three suns are crashing upon a colossal star

An extreme star system is giving new meaning to the phrase "surf's up." The star system intrigued researchers because it is the most dramatic "heartbeat star" on record. Now new models have revealed that titanic waves, generated by tides, are repeatedly breaking on one of the stars in the system-the first time this phenomenon has ever been seen on a star.

On Aug. 12, 2023, NASA's STEREO-A spacecraft will pass between the Sun and Earth, marking the first Earth flyby of the nearly 17-year-old mission. The visit home brings a special chance for the spacecraft to collaborate with NASA missions near Earth and reveal new insights into our closest star.

An improved radioisotope thermoelectric generator could dramatically reduce the weight of interplanetary missions
Monday, 14 August 2023 14:40 Write a comment
Radioisotope thermoelectric generators (RTGs) are the power plants of the interplanetary spacecraft. Or at least they have been for going on 50 years now. But they have significant drawbacks, the primary one being that they're heavy. Even modern-day RTG designs run into the hundreds of kilograms, making them useful for large-scale missions like Perseverance but prohibitively large for any small-scale mission that wants to get to the outer planets. Solar sails aren't much better, with a combined solar sail and battery system, like the one on Juno, coming in at more than twice the weight of a similarly powered RTG.
To solve this problem, a group of engineers from the Aerospace Corporation and the US Department of Energy's Oak Ridge National Lab came up with a way to take the underlying idea of an RTG and shrink it dramatically to the point where it could not potentially be used for much smaller missions.
