Russia deployed space weapon in orbit near US satellite: Pentagon statement
“Russia has deployed this new counter-space weapon in the same orbit as a US government satellite,” he said in remarks ahead of Monday's vote. “Russia's May 16 launch follows potential Russian satellite launches of counter-space systems into low Earth orbit in 2019 and 2022.” In February, the White House said Russia was developing an anti-satellite…

'The danger behind the beauty': More solar storms could be headed our way
Betwi said most countries have improved their power grids, which will prevent long power outages like those that occurred in Sweden in 2003 or Canada in 1989. Still, he suggested that people should have an emergency kit in case there is a power outage for a day or two. Fresh water can also help if…

Spectacular aurora: 'Extreme' solar storm brings celestial light show
Fluctuating magnetic fields associated with geomagnetic storms induce currents in long wires, including power lines, potentially causing blackouts. Long pipelines can also become electrified, causing engineering problems. Spacecraft are also at risk from high doses of radiation, although the atmosphere prevents it from reaching Earth. NASA has a dedicated team overseeing astronaut safety, and can…

Astronomers have finally discovered a rocky planet with an atmosphere
Being so close to its star, any atmosphere should be stripped away by stellar radiation and winds. But dissolved gases in the vast lava ocean covering the planet can keep boiling to refill the atmosphere, Hu said. “The planet may not be habitable because it is so hot that it does not contain liquid water,…

Boeing Starliner crew mission postponed until May 17
United Launch Alliance, the Boeing-Lockheed Martin joint venture responsible for the rocket, initially said the launch would be delayed to at least May 10. But further analysis revealed that the valve was too worn and needed to be replaced. The rocket will be taken back to its hangar for repairs. “NASA's Boeing Crew Flight Test…

Japan Moon Probe Survives Extremely Cold Lunar Night, Is Put to Sleep Again – JAXA
“During this operation, we mainly checked the status of several instruments by turning on switches and applying loads,” JAXA said on social media platform X. “Although there are some glitches in some of the MBC's functions, it still works, so we are carefully checking its condition,” it said, referring to the multi-band camera used to…

Japan's moon lander resurfaces after lunar night
“SLIM managed to survive a night on the lunar surface while maintaining its communications function!” It added that communications were “terminated after a short time, as it was still lunar noon and the temperature of the communications equipment was very high”. But it also says: “Preparations are being made to resume operations once the equipment's…

Scientists identify neutron star born from supernova seen in 1987
“After following supernovae and searching for compact objects for more than three decades, it is exciting to finally find the missing evidence for a neutron star,” said lead author Claes Fransson, professor of astrophysics at Stockholm University in Sweden, to JWST. Thank you.” According to the study published in Science Journal. “Neutron stars are extremely…

America returns spacecraft to the moon, this is the first private sector
The remaining merchandise was sent on behalf of Intuitive Machines' private customers, and includes 125 stainless steel Mini Moons created by artist Jeff Koons. The cargo can last for seven days before lunar night falls, rendering Odysseus inactive. NASA paid Intuitive Machines US$118 million to ship its hardware under a new initiative called Commercial Lunar…

Private American spacecraft flies to the moon
In addition to Astrobotic’s failed effort, two other private initiatives folded: Beresheet, run by an Israeli nonprofit, collapsed in 2019; Whereas Japanese company iSpace also had a “hard landing” last year. Only five nations have succeeded: first the Soviet Union, then the United States, which is still the only country that has even put people…

Japan becomes the fifth country to reach the Moon
SLIM’s goal was to create a crater where the moon’s mantle, typically the deep interior layer beneath its crust, is thought to be exposed at the surface. JAXA said the two probes successfully separated — one with a transmitter and the other designed to orbit around the moon’s surface to send images to Earth. This…

India launches X-ray Polarimeter satellite to study X-ray emissions from celestial sources. ISRO’s XPoSat mission
Emission mechanisms from various astronomical sources such as black holes, neutron stars, active galactic nuclei, pulsar wind nebulae, etc. arise from complex physical processes and are challenging to understand. The precise nature of the emissions from such sources still poses deep challenges to astronomers. Polarimetry measurements add two more dimensions to the understanding, the degree…

SpaceX launches secret US military spacecraft on research mission falcon heavy rocket
“These tests include operating reusable spacecraft in new orbital regimes, experimenting with future space domain awareness technologies, and based on NASA-provided materials,” the U.S. Department of the Air Force Rapid Capabilities Office said in a statement last month. “Includes investigating radiation effects.” It said this is the first time that the The size of a…

Six exoplanets found in synchronous dance around star: clues to our solar system’s formation
Despite not being habitable, they are remarkable in another way: all six planets are precisely coordinated with each other in their orbit. NASA’s Transiting Exoplanet Survey Satellite (TESS) discovered two exoplanets orbiting the star for the first time in 2020. The satellite, known as Exoplanet Hunter, spotted the pair by measuring changes in brightness as…
