Unique use of ESA spacecraft 'housekeeping' data reveals cosmic ray behaviour
Write a comment
Using data originally gathered for spacecraft 'housekeeping' aboard ESA's Rosetta and Mars Express missions, scientists have revealed how intense bursts of high-energy radiation, known as cosmic rays, behave at Mars and throughout the inner Solar System.
Housekeeping data are gathered by most spacecraft and components, and is used by engineering teams to monitor spacecraft health and diagn The discovery of a new type of supernova illuminates a medieval mystery

A worldwide team led by UC Santa Barbara scientists at Las Cumbres Observatory has discovered the first convincing evidence for a new type of stellar explosion - an electron-capture supernova. While they have been theorized for 40 years, real-world examples have been elusive.
They are thought to arise from the explosions of massive super-asymptotic giant branch (SAGB) stars, for which ther Are we missing other Earths

Some exoplanet searches could be missing nearly half of the Earth-sized planets around other stars. New findings from a team using the international Gemini Observatory and the WIYN 3.5-meter Telescope at Kitt Peak National Observatory suggest that Earth-sized worlds could be lurking undiscovered in binary star systems, hidden in the glare of their parent stars. As roughly half of all stars are i Life could exist in the clouds of Jupiter but not Venus

Jupiter's clouds have water conditions that would allow Earth-like life to exist, but this isn't possible in Venus' clouds, according to the groundbreaking finding of new research led by a Queen's University Belfast scientist.
For some decades, space exploration missions have looked for evidence of life beyond Earth where we know that large bodies of water, such as lakes or oceans, exist o Insight Mars Lander may die this year due to dust

The robotic vehicle has been roaming the Martian surface since 2018. Manufactured by Lockheed Martin Space Systems, InSight's main aim is to measure the planet's seismic activity as well as to provide accurate 3D models of its interior.
NASA has revealed that its Martian lander InSight may die this year due to Martian dust. According to the space agency, dust had affected 80 percent of the Study Sheds New Light on Composition at Base of Martian Southern Polar Cap

An earlier discovery of liquid water lakes beneath Mars' south pole may not be as wet as believed, a new paper says. Using the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) radar instrument aboard the European Space Agency's Mars Express orbiter, scientists had earlier detected areas of high radar reflectivity they said were several lakes found deep beneath Martian surface China is using mythology and sci-fi to sell its space programme to the world

On the morning of June 17, China launched its long-awaited Shenzhou-12 spacecraft, carrying three Chinese astronauts - or taikonauts - towards the Tianhe core module. The module itself was launched at the end of April, forming part of the permanent Tiangong space station, which is planned to remain in orbit for the next ten years.

New observations made with ESA’s X-ray XMM Newton telescope have revealed an “orphan cloud” – an isolated cloud in a galaxy cluster that is the first discovery of its kind.
A lot goes on in a galaxy cluster. There can be anything from tens to thousands of galaxies bound together by gravity. The galaxies themselves have a range of different properties, but typically contain systems with stars and planets, along with the material in between the stars – the interstellar medium. In between the galaxies is more material – tenuous hot gas known as the intercluster medium. And sometimes in
LightSail 2 has now been in space for 2 years, and should last even longer before re-entering the atmosphere

The Planetary Society's crowdfunded solar-sailing CubeSat, LightSail 2, launched on June 25th 2019, and two years later, the mission is still going strong. A pioneering technology demonstration of solar sail capability, LightSail 2 uses the gentle push of photons from the Sun to maneuver and adjust its orbital trajectory. Within months of its launch, LightSail 2 had already been declared a success, breaking new ground and expanding the possibilities for future spacecraft propulsion systems. Since then, it's gone on to test the limits of solar sailing in an ongoing extended mission.
One of the primary goals of that extended mission is to try out the spacecraft in different modes of operation, learning along the way how to sail efficiently and effectively. Even though two years of flying in the harsh orbital environment has begun to degrade the sail, software updates, learned experience, and careful debugging efforts have ensured that LightSail 2 is still flying exceptionally well. Shrinkage, crinkles, and delamination need to be continually monitored, but in spite of them, the team reports that LightSail 2's current "orbit decay rates…are the lowest we've seen since the early days of the mission.
Unique exoplanet photobombs Cheops study of nearby star system

While exploring two exoplanets in a bright nearby star system, ESA’s exoplanet-hunting Cheops satellite has unexpectedly spotted the system’s third known planet crossing the face of the star. This transit reveals exciting details about a rare planet “with no known equivalent”, say the researchers.
