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 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 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.

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 Unique use of ESA spacecraft 'housekeeping' data reveals cosmic ray behaviour

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.

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

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.
LightSail 2 has now been in space for 2 years, and should last even longer before re-entering the atmosphere
Monday, 28 June 2021 13:40 Write a comment
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.
South Korea’s top airline to develop propellant tank for smallsat launcher

SEOUL, South Korea — Korean Air, South Korea’s biggest airline, says it will develop common bulkhead propellant tanks for small satellite launch vehicles as part of the Ministry of Science and ICT’s “Space Pioneer” project.
The ministry plans to invest 211.5 billion won ($186.6 million) by 2030 in the “Space Pioneer” project, which aims to strengthen the global competitiveness of the domestic aerospace industry by reducing dependence on overseas products.
Giant comet found in outer solar system by Dark Energy Survey

A giant comet from the outskirts of our Solar System has been discovered in 6 years of data from the Dark Energy Survey. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times. It has an extremely elongated orbit, journeying inward from the distant Oort Cloud over millions of years. It i AFRL leaps forward in NTS-3 spacecraft development
