NASA and the Russian space agency Roscosmos are evaluating if they will need to mount a rescue mission to the International Space Station after discovering a coolant leak from the Russian Soyuz spacecraft currently docked at the station.
The leaking spacecraft, designated Soyuz MS-22, carried U.S. astronaut Frank Rubio, along with cosmonauts Dmitri Petelin and Sergey Prokopyev to the In NASA, Alaska researchers to scan asteroid with radio waves

Researchers are preparing for a potentially "catastrophic" close encounter with an asteroid in 2029 by scanning an asteroid with radio waves on Tuesday.
NASA is teaming with scientists from the University of Alaska Fairbanks' Geophysical Institute to send about 9.6 million radio waves to 2010 XC15, an asteroid that will pass by about twice the distance from Earth to the Moon.

Researchers have uncovered a previously hidden heating process that helps explain how the atmosphere that surrounds the Sun called the "solar corona" can be vastly hotter than the solar surface that emits it.

There's an old adage in the engineering field—what gets funded gets built. So it's sure to be a happy time over at the Planetary Society, as NEO Surveyor, the project the organization has primarily supported over the past few years, has made it through NASA's grueling budgetary process to reach the "development" stage, with an eye for a launch of the system in 2028.
NEO Surveyor is, as the name implies, a satellite specifically designed to survey for objects near the Earth (NEO). One of its primary contributions will be to look for asteroids and other small bodies that are potentially on an eventual collision course with Earth but are invisible to typical NEO survey missions because of their location in the solar system.
Typically, their signals are just background noise against the overwhelming signal from the sun. But NEO Surveyor will be able to detect individual asteroid heat signatures, allowing it to isolate potentially dangerous asteroids using this novel technique.
Is mining in space socially acceptable?
Tuesday, 27 December 2022 16:31 Write a comment
Traditional mining has been subject to a negative stigma for some time. People, especially in developed countries, have a relatively negative view of this necessary economic activity. Primarily that is due to its environmental impacts—greenhouse gas emissions and habitat destruction are some of the effects that give the industry its negative image.
Mining in space is an entirely different proposition—any greenhouse gases emitted on the moon or asteroids are inconsequential, and there is no habitat to speak of on these barren rocks. So what is the general public's opinion on mining in space? A paper published in Sustainability by a group of researchers in Australia, one of the countries most impacted by the effects of terrestrial mining, now gives us an answer.
Strangely, as the paper points out, no one had previously studied this particular aspect of space resources. Despite the general media interest in ventures such as Planetary Resources and the success of missions such as Hayabusa-2, no one had attempted to understand how the general public felt about space mining.
Five space exploration missions to look out for in 2023

It's been an eventful year for space exploration, with successes including the completion of Nasa's Artemis 1 mission (finally), the inauguration of the James Webb Space Telescope, and the completion of China's Tiangong space station.
2023 is set to be another busy year. Here are five of the most exciting missions to watch out for.
1. Jupiter Icy Moons Explorer
In April, the European Space Agency (ESA) is set to launch the Jupiter Icy Moons Explorer (Juice), in what will be Europe's first dedicated robotic mission to Jupiter. Juice is due to reach the planet in July 2031 after performing an incredible flight path through the solar system. The mission will enter into orbit around Jupiter and perform numerous flybys of its large icy moons: Europa, Ganymede and Callisto.
After four years of moon flybys, Juice will then enter into orbit around Ganymede, the largest moon in the solar system—becoming the first spacecraft ever to reach orbit around the moon of another planet.

Perseverance has a unique device near its heart that inhales Mars' atmosphere and exhales pure oxygen. This device is named MOXIE, the Mars Oxygen In Situ Resource Utilization Experiment.
The toaster-sized MOXIE uses a high-temperature, electrochemical process called solid oxide electrolysis to strip oxygen ions from the carbon dioxide in the atmosphere of Mars. There are two little gas ex IXPE quickly observes aftermath of exceptional cosmic blast

On Oct. 9, 2022, NASA's Fermi Gamma-ray Space Telescope and Neil Gehrels Swift Observatory detected a high-energy blast of light from deep space. The light came from a powerful explosion called a gamma-ray burst dubbed GRB 221009A that ranks among the most luminous known. Scientists around the world trained their telescopes on the aftermath.

A new study involving UCL has uncovered how magnetic waves are transmitted past a standing shock wave, known as the bow shock, that forms ahead of Earth as a result of the solar wind hitting our magnetic bubble (magnetosphere).
Shock waves occur in air when a plane travels faster than the speed of sound and also occur in plasma (a fourth state of matter that makes up 99% of the visible Uni Hickenlooper Bill to clear space junk, protect space exploration, passes Senate unanimously

When winter comes to Mars, the surface is transformed into a truly otherworldly holiday scene. Snow, ice, and frost accompany the season's sub-zero temperatures. Some of the coldest of these occur at the planet's poles, where it gets as low as minus 190 degrees Fahrenheit (minus 123 degrees Celsius).

When NASA's Mars rovers found manganese oxides in rocks in the Gale and Endeavor craters on Mars in 2014, the discovery sparked some scientists to suggest that the red planet might have once had more oxygen in its atmosphere billions of years ago.
The minerals probably required abundant water and strongly oxidizing conditions to form, the scientists said. Using lessons learned from Earth's InSight goes silent as Martian dust and cold ends mission

The InSight Mars mission is history. On 20 December 2022, NASA declared the mission over. The two attempts from Mission Control Centre at NASA's Jet Propulsion Laboratory (JPL) in Southern California to reach the lander via relay satellites in Mars orbit have been unsuccessful.

An experiment to bounce a radio signal off an asteroid on Dec. 27 will serve as a test for probing a larger asteroid that in 2029 will pass closer to Earth than the many geostationary satellites that orbit our planet.
