Understanding astronaut muscle wasting at the molecular level

Researchers from the University of Tsukuba have sent mice into space to explore effects of spaceflight and reduced gravity on muscle atrophy, or wasting, at the molecular level.   Gravity is a constant force on Earth, which all living creatures have evolved to rely on and adapt to. Spac

Chinese rocket to tumble back to Earth in uncontrolled re-entry

A large segment of a Chinese rocket is expected to make an uncontrolled re-entry into the Earth's atmosphere over the weekend, but Beijing has downplayed fears of damage on the ground and said the risk is very low.   A Long March-5B rocket launched the first module of China's new space

Scientists scramble to determine landing site of Chinese rocket debris

A Chinese rocket, which last week carried a module to an under-construction space station, has dropped into Earth’s low orbit and could crash-land on an inhabited area on the surface, it was announced on Wednesday. The Long March 5B rocket recently launched the first module for China’

New model can predict carbon cycle presence on exoplanets

Life thrives at stable temperatures. On Earth, this is facilitated by the carbon cycle. Scientists at SRON, VU and RUG have now developed a model that predicts whether there is a carbon cycle present on exoplanets, provided the mass, core size and amount of CO2 are known. Publication in 

NASA's Parker Solar Probe has gone faster than any spacecraft ever

The fastest spacecraft ever built has nearly touched the sun. NASA’s Parker Solar Probe, which launched in 2018, has set two records at once: the closest spacecraft to the sun and the highest speed reached. On 29 April, the probe made its closest pass yet to the sun, a little more than 10 m

Mars helicopter makes 4th flight, gets extra month of flying

After proving powered, controlled flight is possible on the Red Planet, NASA's Mars Ingenuity helicopter has new orders: scout ahead of the Perseverance rover to assist in its search for past signs of microbial life.   The next phase extends the rotocraft's mission beyond the original m

How long is a day on Venus? Scientists crack mysteries of our closest neighbor

Venus is an enigma. It's the planet next door and yet reveals little about itself. An opaque blanket of clouds smothers a harsh landscape pelted by acid rain and baked at temperatures that can liquify lead.   Now, new observations from the safety of Earth are lifting the veil on some of

US Apollo 11 astronaut Michael Collins dies at 90

American astronaut Michael Collins, who stayed behind in the command module of Apollo 11 on July 20, 1969, while Neil Armstrong and Buzz Aldrin travelled to the lunar surface to become the first humans to walk on the moon, died on Wednesday at age 90, his family said. A statement released by his

China is about to start building a space station in orbit

China is about to launch the first section of a new space station, beginning an orbital construction project that is expected to end in 2022 with an outpost about a quarter of the size of the International Space Station (ISS). While the exact date hasn’t been announced, China is expected to

NASA Extracts Breathable Oxygen on March

NASA's Perseverance rover has logged another extraterrestrial first on its latest mission to Mars: converting carbon dioxide from the Martian atmosphere into pure, breathable oxygen. "This is a critical first step at converting carbon dioxide to oxygen on Mars," said Jim Reuter, associate adminis

Mars helicopter snaps first aerial colour image and prepares for third flight test

Nasa's Ingenuity Mars Helicopter has captured the first colour image of the Martian surface. The Ingenuity Mars Helicopter captured it with its colour camera during its second successful flight test on April 22, the US space agency said in a statement. While capturing the image, Ingenuity was 17

Biggest space station crowd in decade after SpaceX arrival

The International Space Station's population swelled to 11 on Saturday with the jubilant arrival of SpaceX's third crew capsule in less than a year.   It's the biggest crowd up there in more than a decade. All of the astronauts—representing the U.S., Russia, Japan and France&mdas

SpaceX rocketship launches 4 astronauts on NASA mission to space station

NASA and Elon Musk's commercial rocket company SpaceX launched a new four-astronaut team on a flight to the International Space Station on Friday, the first crew ever propelled into orbit by a rocket booster recycled from a previous spaceflight. The company's Crew Dragon capsule Endeavour, also m

How to watch SpaceX launch astronauts to the space station

SpaceX is preparing to launch a team of astronauts to the international space station (ISS) on Friday – the second crewed flight of its Crew Dragon spacecraft. Managers from Nasa, the European Space Agency and the Japan Aerospace Exploration Agency, the three space agencies whose astro

Hubble watches cosmic light bend

This extraordinary image from the NASA/ESA Hubble Space Telescope of the galaxy cluster Abell 2813 (also known as ACO 2813) has an almost delicate beauty, which also illustrates the remarkable physics at work within it. The image spectacularly demonstrates the concept of gravitational lensing. Am

NASA chooses SpaceX to take humans back to Moon

NASA has selected SpaceX to land the first astronauts on the surface of the Moon since 1972, the agency said Friday, in a huge victory for Elon Musk's company. The contract, worth $2.9 billion, involves the prototype Starship spacecraft that is being tested at SpaceX's south Texas facility. "Tod

A new super-Earth detected orbiting a red dwarf star

In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and masses between 0.08 and 0.45 solar masses. In this context, a team of

New NASA visualization probes the light-bending dance of binary black holes

A pair of orbiting black holes millions of times the Sun's mass perform a hypnotic pas de deux in a new NASA visualization. The movie traces how the black holes distort and redirect light emanating from the maelstrom of hot gas—called an accretion disk—that surrounds each one.
