Acceleration of nuclear power development is part of the Trump administration’s efforts to focus NASA on human spaceflight

If they were first, China and Russia “could potentially declare a keep-out zone” that would inhibit what the United States could do there, Mr. Duffy said.

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…

2024 YR4
When discovered, asteroid 2024 YR4 appeared to have a small chance of impacting Earth on Dec. 22, 2032. Experts now think it poses no significant risk to Earth.

Transportation Secretary Sean Duffy, who has vehemently described the New York City subway as a hellscape, has been named to oversee NASA — putting him in charge of rocket ships that are far more dangerous than public transit.
After Donald Trump pulled the nomination of tech entrepreneur Jared Isaacman for the post, the president announced Duffy would be the interim NASA administrator.
Trump made the announcement on Truth Social, praising the former Real World cast member: “Sean i…

The TESS Grand Unified Hot Jupiter Survey. III. Thirty More Giant Planets
We present the discovery of 30 transiting giant planets that were initially detected using data from NASA's Transiting Exoplanet Survey Satellite (TESS) mission. These new planets orbit relatively bright ($G \leq 12.5$) FGK host stars with orbital periods between 1.6 and 8.2 days, and have radii between 0.9 and 1.7 Jupiter radii. We performed follow-up ground-based photometry, high angular-resolution imaging, high-resolution spectroscopy and radial velocity monitoring for each of these objects …

Signal processing and data acquisition system for the BTO detectors onboard COSI
The energy range from a few hundred keV to a few MeV includes important probes such as nuclear gamma-rays and the 511 keV annihilation line. However, compared to X-rays and GeV/TeV gamma-rays, this range suffers from lower sensitivity by orders of magnitude. The upcoming NASA SMEX satellite mission Compton Spectrometer and Imager (COSI), scheduled for launch in 2027, is expected to break through this limitation with its Compton telescope utilizing a germanium semiconductor detector, covering th…

The Trump administration on Monday took another step to make it harder to find major, legally mandated scientific assessments of how climate change is endangering the nation and its people.
Earlier this month, the official government websites that hosted the authoritative, peer-reviewed national climate assessments went dark.
Such sites tell state and local governments and the public what to expect in their backyards from a warming world and how best to adapt to it.
At the …

NASA website won't publish major climate change reports
The Trump administration has made it harder for people, local and state governments to find critical climate change reports. On Monday, NASA announced it would not host the National Climate Assessments, reversing earlier plans. These reports detail climate impacts across the U.S. and were previously available on government websites that went offline earlier this month. NASA stated it has no legal obligation to host the data. Critics, including scientists, accuse the administration of trying to …

Hi, this is EDF Action Votes.
Donald Trump is ordering NASA to shut down its
carbon-monitoring satellites
— the very tools we use to track carbon emissions, plant health, wildfire risk, and extreme weather patterns.
This is not about saving money.
It’s about blinding America to the truth of climate change.
If Trump gets his way, we’ll be flying blind in the face of rising disasters
— and Big Polluters will have a free pass to keep hiding the damag…

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

NASA’s NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, has paused observations due to a problem with one of the motors that drives its ability to track cosmic objects: #NICER team paused operations June 17 when performance degradation in the motor began affecting science observations. Engineers are investigating the cause and potential solutions.

50 years ago today, at 16:09 UTC on 17 July 1975, the Apollo-Soyuz Test Project culminated in the first docking of the spacecraft - but afterwards an interesting experiment took place: after they separated again Apollo (the final one; no number) occulted the Sun from the point of view of Soyuz 19. Images obtained show mostly outgassing from Apollo forward-scattering light from the hidden Sun but allegedly there is also some outer corona in the images of which #eclipse experiment was described in the mission press kit https://www.nasa.gov/wp-content/uploads/static/history/astp/documents/astp press kit (us).pdf on PDF pages 37-39 and the outcome is discussed in the didactical NASA brochure https://ntrs.nasa.gov/api/citations/19780019206/downloads/19780019206.pdf on PDF pages 20-27; there is apparently also a more technical paper in a mission science report but I couldn't find that one online.
