The Land Surveyor 4A, the world's first synthetic aperture radar satellite in high-altitude orbit, has successfully moved into its preset orbital position and has unfolded its radar antennas, according to the China National Space Administration. Dedicated to natural disaster prevention and mitigation, the remote-sensing satellite was carried into orbit on a Long March 3B rocket that was la

The quest for the true value of the Hubble constant (H0) tension which gives a measure of the current expansion of the Universe is still on. The fervent debate today is about the discrepancy between the H0 values obtained from type Ia supernovae (SNe Ia) and from the Cosmic Microwave Background Radiation (CMB), a radiation emitted from the early Universe close to its origin. Because of thi

Crew-7 has arrived at NASA’s Kennedy Space Center in Florida, USA, in the run-up to the International Space Station launch.

Crew-7 consists of ESA astronaut Andreas Mogensen, taking the role of Dragon spacecraft pilot, NASA astronaut Jasmin Moghbeli is commander, Satoshi Furukawa from JAXA and Konstantin Borisov from Roscomos are mission specialists.

This video shows scenes of Crew-7 arriving at the Kennedy Space Center, during launch rehearsal, and Andreas Mogensen training for his mission in space.

Andreas and Crew-7 will launch in the SpaceX Crew Dragon spacecraft Endurance from launch pad 39A. This is the launch pad for all crewed

A study of 14 astronauts suggests that while space travel depletes red blood cells and bone, the body can eventually replenish them back on Earth with the help of fat stored in the bone marrow. The study, published in Nature Communications, has important implications for health in space and on Earth. "We found that astronauts had significantly less fat in their bone marrow about a month af

Scientists spectacularly confirmed the existence of gravitational waves several years ago, but now they are searching the cosmos for new and different types of these waves that result from different objects in deep space. Benjamin Owen, a professor in the Department of Physics and Astronomy at Texas Tech University, was recently awarded a three-year National Science Foundation (NSF) grant

The Pentagon announced Monday it has awarded $1.5 billion to contractors Northrop Grumman and Lockheed Martin for a "swarm" of 72 tiny prototype satellites meant to detect incoming enemy missiles. The Space Development Agency said each company will build and operate 36 of the satellites, with approximately $816 million going to Lockheed Martin and $733 million to Northrop Grumman for the p

In the middle of the last century, physicists found that protons can resonate, much like a ringing bell. Advances over the last three decades have led to 3D pictures of the proton and significant insight into its structure in its ground state. But little is known about the 3D structure of the resonating proton. Now, an experiment to explore the 3D structures of resonances of protons and ne

New research has improved the accuracy of the parameters governing the expansion of the Universe. More accurate parameters will help astronomers determine how the Universe grew to its current state, and how it will evolve in the future. It is well established that the Universe is expanding. But with no landmarks in space, it is difficult to accurately measure how fast it is expanding. So,

The intricate dance of cosmic dust microparticles in the vastness of space may seem insignificant. Still, understanding their behaviors is key to unraveling one of the universe's most profound mysteries: How do planets form? A groundbreaking study spearheaded by Japan's JAMSTEC (Japan Agency for Marine-Earth Science and Technology) offers valuable insights into the process and has highlighted so

The search for exoplanets - planets that orbit stars located beyond the borders of our solar system - is a hot topic in astrophysics. Of the various types of exoplanets, one is hot in the literal sense: hot Jupiters, a class of exoplanets that are physically similar to the gas giant planet Jupiter from our own neighborhood. Unlike "our" Jupiter, hot Jupiters orbit very close to their stars, comp
