The increasing commercialisation of space travel - often referred to as 'New Space' - will lead to significantly more spacecraft launches. More than 15,000 new satellites are expected to be launched in the current decade. Many of these satellites will be used for communications, navigation or Earth observation. To ensure continuity of operations, regular replacement of some of these satellites w NASA's Perseverance rover cameras capture Mars like never before

Scientists tap into an array of imagers aboard the six-wheeled explorer to get a big picture of the Red Planet.
NASA's Perseverance rover has been exploring Jezero Crater for more than 217 Earth days (211 Martian days, or sols), and the dusty rocks there are beginning to tell their story - about a volatile young Mars flowing with lava and water.

The lander cleared enough dust from one solar panel to keep its seismometer on through the summer, allowing scientists to study the three biggest quakes they've seen on Mars.
On Sept. 18, NASA's InSight lander celebrated its 1,000th Martian day, or sol, by measuring one of the biggest, longest-lasting marsquakes the mission has ever detected. The temblor is estimated to be about a magnitud Peering into the Moon's shadows with AI

The Moon is a cold, dry desert. Unlike the Earth, it is not surrounded by a protective atmosphere and water which existed during the Moon's formation has long since evaporated under the influence of solar radiation and escaped into space. Nevertheless, craters and depressions in the polar regions give some reason to hope for limited water resources.

Engineers at the University of Cincinnati are developing new ways to convert greenhouse gases to fuel to address climate change and get astronauts home from Mars.
UC College of Engineering and Applied Science assistant professor Jingjie Wu and his students used a carbon catalyst in a reactor to convert carbon dioxide into methane. Known as the "Sabatier reaction" from the late French chemi Come on in, the water is superionic

The interiors of Uranus and Neptune each contain about 50,000 times the amount of water in Earth's oceans, and a form of water known as superionic water is believed to be stable at depths greater than approximately one-third of the radius of these ice giants.
Superionic water is a phase of H2O where hydrogen atoms become liquid-like while oxygen atoms remain solid-like on a crystalline lat Cloud-spotting on a distant exoplanet

An international team of astronomers has not only detected clouds on the distant exoplanet WASP-127b, but also measured their altitude with unprecedented precision. A presentation by Dr Romain Allart at the Europlanet Science Congress (EPSC) 2021 shows how, by combining data from a space- and a ground-based telescope, the team has been able to reveal the upper structure of the planet's atmospher Cloudy days on exoplanets may hide atmospheric water

Water is a hot topic in the study of exoplanets, including "hot Jupiters," whose masses are similar to that of Jupiter, but which are much closer to their parent star than Jupiter is to the sun. They can reach a scorching 2,000 degrees Fahrenheit (1,100 degrees Celsius), meaning any water they host would take the form of water vapor.

When the universe was about 3 billion years old, just 20% of its current age, it experienced the most prolific period of star birth in its history. But when NASA's Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile gazed toward cosmic objects in this period, they found something odd: six early, massive, "dead" galaxies that had run out of the col Gigantic cavity in space sheds new light on how stars form

Astronomers analyzing 3D maps of the shapes and sizes of nearby molecular clouds have discovered a gigantic cavity in space. The sphere-shaped void, described in The Astrophysical Journal Letters, spans about 150 parsecs - nearly 500 light years - and is located on the sky among the constellations Perseus and Taurus.

This Hubble picture exemplifies the fact that the universe is a vast stage for grand illusions. Albert Einstein realized this a century ago as he formulated his law of general relativity. Gravity, he said, warped space like stretching and twisting a rubber sheet.

Elon Musk says Inspiration4 crew had 'challenges' with toilet, vows for bathroom upgrades
Thursday, 23 September 2021 19:05
The private space flight, SpaceX, completed a historic mission with the first all-civilian flight crew last weekend. The four members of the Inspiration4 crew raised $200 million for St. Jude Children's Research Hospital, and helped prove SpaceX founder Elon Musk's belief that non-professional astronauts can venture into space in regularity.
Every successful mission has its learning moments, however. One key takeaway from a three-day trip in space: Spacecraft bathrooms aren't ideal whatsoever.
In responding to followers asking about the mission, Musk tweeted Monday night that the Inspiration4 crew had some difficulties with the bathroom and promised upgrades for future missions.
"Definitely upgraded toilets :) We had some challenges with it this flight," Musk tweeted. The billionaire also promised better WiFi and oven.
While Musk didn't elaborate (for which we'll thank him), Inspiration4 member Jared Isaacman told Insider in July the facilities were located near the spacecraft's large cupola window.
"It's not a ton of privacy," he said. "But you do have this kind of privacy curtain that cuts across the top of the spacecraft, so you can kind of separate yourself from everyone else.
