Enhancing the Quality of 3D Lunar Maps Using JAXA's Kaguya Imagery
As global efforts to explore the Moon intensify, the need for high-quality 3D lunar maps becomes increasingly critical-particularly for long-distance missions such as NASA's Endurance mission concept, in which a rover aims to traverse 2,000 km across the South Pole-Aitken basin. Kaguya TC (Terrain Camera) images, though globally available at 10 m/pixel, suffer from altitude inaccuracies caused by stereo matching errors and JPEG-based compression artifacts. This paper presents a method to improv…

NASA aims to establish a sustainable human basecamp on the Moon as a stepping stone for future missions to Mars and beyond.

However, current methods to access lunar ice deposits are limited. While rovers have been used to explore the lunar surface for decades, they face significant challenges in navigating harsh…

Revisiting the Radius Valley Across Stellar Types: A Transit-Only Analysis of M, K, G, and F Stars with Updated NASA Exoplanet Archive Data
The radius valley -- a deficit of exoplanets between super-Earths and sub-Neptunes -- is a key diagnostic of planet formation and atmospheric evolution. We investigate how the radius valley depends on stellar type by analyzing an updated, transit-only sample of exoplanets from the NASA Exoplanet Archive. Planets are selected with $P < 100$ days and divided by host spectral class (M, K, G, F). We construct weighted radius distributions and apply statistical tests to quantify the valley depth. We…

The Alfvén surface -- where the solar wind exceeds the local Alfvén speed as it expands into interplanetary space -- is now routinely probed by NASA's Parker Solar Probe (PSP) in the near-Sun environment. The size of the Alfvén surface governs how efficiently the solar wind braking torque causes the Sun to spin-down. We aimed to characterise the size and evolution of the Alfvén surface as magnetic activity increased during solar cycle 25. The Alfvén surface was extrapolated from the solar …

SpaceX defends lunar lander after challenge from NASA administrator
In a lengthy blog post Thursday, Elon Musk’s space company said it “rapidly advanced” the core Starship spacecraft through 11 test flights
and reached 49 milestones in developing the HLS (Human Landing System) version of the craft designed to reach the lunar surface as part of the government’s Artemis program.
“Starship continues to simultaneously be the fastest path to returning humans to the surface of t…

An analysis of a rock sampled by NASA's #Perseverance #Mars rover last year called “Sapphire Canyon” will be discussed in a press conference at the top of the hour: #Jezero Crater long ago.

Hi, it’s the team at EDF Action Votes.
Trump’s administration just ordered NASA to shut down two crucial satellites
that track carbon emissions and monitor vegetation health worldwide.
One would even be destroyed, burning up in Earth’s atmosphere — erasing decades of critical climate data.
This is deliberate sabotage of science,
and it puts every American at risk.
Without these satellites, we’ll be flying blind in the fight against climate change.

I just gave to EDF Action Votes!
EDF Action votes is doing everything they can to elect environmental champions who will take climate action.

The super-successful #Juno #Jupiter orbiter may already be switched off, but #NASA won't say: https://www.space.com/space-exploration/missions/nasas-juno-probe-orbiting-jupiter-may-have-come-to-an-end-but-no-one-can-confirm - the agency has extended Juno's mission multiple times, most recently in 2021, guaranteeing operations through Sept. 30, 2025; that date has now passed, and with the U.S. government shut down, there is no word yet on whether Juno will come out alive on the other side.

All eyes on #3I/ATLAS ☄️
Our Mars Express & ExoMars Trace Gas Orbiter will observe the comet around its closest approach to Mars on 3 October 2025, when 3I/ATLAS will be around 30 million km from the red planet.

ESA observations of interstellar comet 3I/ATLAS
The European Space Agency (ESA) reacted promptly to the discovery of comet 3I/ATLAS on 1 July 2025. Soon after they were alerted to its existence by automated detection systems, ESA astronomers began using ground-based telescopes in Hawaii, Chile, and Australia to monitor its progress.Since then, the comet has been observed by space telescopes close to Earth, including the NASA/ESA Hubble Space Telescope and the NASA/ESA/CSA James Webb Space Telescope.In the coming months, ESA will turn interp…

Acting NASA administrator Sean Duffy
emphasized his desire to end NASA's focus on studying the Earth and understanding how the planet's surface and atmosphere are changing.
This shift has been a priority of the Trump Administration at other federal agencies.

NASA’s acting chief calls for the end of Earth science at the space agency
NASA’s charter clearly states the agency should study planet Earth, however.

A previously unknown regular satellite of #Uranus has been detected in a series of images obtained by the Near-Infrared Camera (NIRCam) onboard the James Webb Space Telescope on 2025 Feb. 2: http://www.cbat.eps.harvard.edu/iau/cbet/005500/CBET005593.txt -> https://science.nasa.gov/blogs/webb/2025/08/19/new-moon-discovered-orbiting-uranus-using-nasas-webb-telescope/ - the object is located at a projected radial distance of 56250 /- 250 km from Uranus' center in the planet's equatorial plane, initial astrometry is consistent with the moon orbiting on a nearly circular orbit with an orbital period 0.402 days, and the observed IR flux from the object indicates a radius of 4 - 5 km, placing it well below the detection threshold of earlier images from Voyager and the Hubble Space Telescope.
