How did ESA’s gamma ray-spotting 'scope make it to 20? They totally overdid it
This week, the European Space Agency’s International Gamma-Ray Astrophysics Laboratory (Integral) spacecraft celebrated the 20th anniversary of its launch – although it was only meant to last five years.

Mars rover Curiosity reaches sulfate-rich Mount Sharp after 10-year journey
NASA’s long-serving Curiosity Mars rover has finally reached an objective it has been ambling toward since landing on the red planet a decade ago: the “sulfate-bearing unit” of Mount Sharp.
The region was first spotted by the Mars Reconnaissance Orbiter, which has been studying the Gale Crater region of Mars since 2006. NASA flagged the area for investigation because of a high concentration of salty minerals that suggests it was once covered in water.

We’ve seen things you people wouldn’t believe. A planet, dense as a marshmallow, that would float on water
Located 580 light-years away from Earth in the constellation of Auriga the Charioteer, there lies an extra fluffy exoplanet with an average density similar to a marshmallow, light enough to float on water.
The planet, code-named TOI-3757 b, is the lowest-density planet found around a red dwarf star yet, according to a study published in The Astrophysical Journal. With an average density of just 0.27 grams per cubic centimetre, TOI-3757 b has a density less than half of Saturn and about a quarter the density of water.
The Jupiter-sized gas giant would, theoretically, float in a bathtub of water – if the tub were large enough for the planet’s 150,000-kilometre (100,000-mile) diameter. A large team of boffins calculated the exoplanet’s density by poring over data collected by ground-based and space telescopes.

Starlink decoded for use as GPS alternative – without Elon Musk’s help
Researchers rebuffed by SpaceX have taken matters into their own hands and reverse-engineered Starlink’s satellite signal for potential use as a GPS alternative.
University of Texas Austin professor Todd Humphreys and his team claim in a non-peer reviewed paper that they’ve managed to decode Starlink downlink signals in the 10.7 to 12.7 GHz band detailed enough that they were able to locate a Starlink receiver to within 30 metres.
That’s not as accurate as traditional GPS, but it’s noteworthy since Humphreys’ team managed to do it without any SpaceX help. If Musk and company decided to play ball, Humphreys told us, Starlink positioning could become more accurate than GPS with little work.
Humphreys’s team has been working on the technique since 2020, when talks between the US Army, his team at UT and and SpaceX ended with a decree from His Muskiness: “every other [low Earth orbit] communications network has gone into bankruptcy, and so we [SpaceX] have to focus completely on staying out of bankruptcy. We cannot afford any distractions,” Humphreys said Musk had decided.
