Fusées, satellites, stations, la Lune et Mars : lancements, essais et économie de l’orbite.
Mis à jour
Both NASA ESCAPADE spacecraft built by Rocket Lab fired engines during an Earth gravity assist and now point toward Mars, with arrival expected in September 2027.
Simulations constrained by 56,229 measured craters give degradation rates for 50–500 m craters on the Moon; small cold traps are short-lived, so their ice is recent.
The model uses Inouye telescope images and scaling laws from near-Earth spacecraft data to estimate how the corona is heated to more than a million degrees.
SpaceX published photos of ground tests in which the Super Heavy B22 booster was lifted to catch height. Flight 15 is planned for 14 November, but the FAA licence has not yet been issued.
The transit chord of TOI-2535b moved off the stellar disk. Per TESS and NEID data, the authors link this to a nearby, mutually inclined planet in resonance.
A theoretical analysis in The Astrophysical Journal shows how a planet's Doppler modulation adds sidebands to a gravitational-wave signal; the method favours massive, long-period planets.
A review in The Innovation says high-spectral-resolution lidar on China's DQ-1 and Europe's EarthCARE replaces assumptions with measurement of subsurface plankton.
The Australian companies will build a body-mounted panel with copper-metallised HJT cells and test it in thermal vacuum. SMC says Australian programs now import arrays.
Mid-infrared JWST spectra of the central 0.1 pc show mildly supersolar abundances and signs of fast shocks in compact gas clumps moving at over 600 km/s.
Chinese researchers found γ-Fe, a high-temperature iron phase not previously documented in lunar samples, preserved at ambient temperature as nanoparticles with a magnetic vortex state.
JWST observations of the lava planet TOI-561 b over 37 hours indicate an atmosphere, possibly with reflective silicate clouds on the dayside, according to the authors.
X-ray data suggest the giant star in galaxy NGC 4559, which mimics a supernova about every 113 days, feeds a black hole or neutron star on an elongated orbit.
Argo Space, a company with fewer than 30 employees, is building a spacecraft that splits water into hydrogen and oxygen for combustion. Its July demonstration did not test the propulsion.
Hera's Asteroid Framing Camera imaged the 780-m Didymos, on the side DART did not show. The data will help assess kinetic-impact asteroid deflection.
Authors used rover X-ray fluorescence data to examine fine and ultrafine Martian dust directly; respirable particles of this size matter for the health of future crews.
SuperCam recorded narrow luminescence peaks at 692.7 and 694.1 nm from chromium in corundum, a mineral not expected on a planet without plate tectonics.
Spectroscopic observations reveal rapid redistribution of carbon, oxygen, and silicon into gas around early galaxies within 500 million years of the Big Bang.
Data from the Vera C. Rubin Observatory revealed an icy body that could become the solar system's sixth recognized dwarf planet.
Europe's Prometheus prototype demonstrated multiple restarts without a starter system and verified a cold-gas-sprayed combustion chamber.
Numerical simulations reveal that atmospheric entry and impact pyrolysis destroy most prebiotic hydrogen cyanide delivered to Earth, while Mars preserves significantly more.
