HELSINKI — U.S. space tracking has detected a new object orbiting along with China's recently launched Shijian-21 space debris mitigation technology satellite.
Shijian-21 was launched into geosynchronous transfer orbit Oct. 23 by a Long March 3B rocket. Chinese state media reported that the satellite would "test and verify space debris mitigation technologies," but no further details have been revealed.
New Engineering Method Can Clean Up Space Junk With Magnets
According to NASA, there are more than 27,000 pieces of space debris bigger than the size of a softball currently orbiting Earth, and they are traveling at speeds of up to 17,500 mph, fast enough for a small chunk to damage a satellite or spacecraft like an intergalactic cannonball.
Astronomers want a huge telescope optimized for studying alien worlds : NPR
That's according to a new report from the National Academies of Sciences, Engineering, and Medicine.
That's why the expert panel's "top recommendation for a mission," says Harrison, was a telescope significantly larger than the Hubble Space Telescope that would be capable of blocking out a star's bright light in order to capture the much dimmer light coming from a small orbiting planet.

A decades-old mystery about the Andromeda galaxy might have just been solved. The galaxy's central supermassive black hole is orbited by star clusters in a peculiar formation, and researchers now believe that a collision with another supermassive black hole caused this.
NASA's Jet Propulsion Laboratory Adds New Stops to Its Virtual Tour
While NASA's Perseverance Mars rover makes groundbreaking achievements on the Red Planet, its twin is hard at work in JPL's Mars Yard. The Operational Perseverance Twin for the Integration of Mechanisms and Instruments Sent to Mars, or OPTIMISM, is the Mars 2020 Vehicle System Testbed (VSTB)
Now you can see the Mars Yard up close, roam the world-class Microdevices Lab, visit the shop where spacecraft parts are made, and stop into a clean room where spacecraft take shape.
Rocky exoplanets are even stranger than we th | EurekAlert!

An astronomer from NSF’s NOIRLab has teamed up with a geologist from California State University, Fresno, to make the first estimates of rock types that exist on planets orbiting nearby stars.
NASA DART tests against future asteroids hitting Earth
Later in November, NASA will launch its first major test of humankind’s planetary defenses. A cube-shaped spacecraft will begin a 10-month journey across the universe, fated to meet with orbiting double asteroids Dimorphos and Didymos 7 million miles from Earth.
But there’s no reason to panic now: Neither Dimorphos nor Didymos pose any danger to planet Earth, and their redirection is merely a prudent engineering exercise.
Frozen planet Pluto surprises observers with its topography - Skywatching - Castanet.net
Pluto is a small, rocky object, smaller than the Moon, orbiting the Sun in a wildly elliptical path ranging from 30 to 50 times the Earth-Sun distance, taking it from closer than Neptune to far beyond the outermost planet.
It takes about 248 years to complete each trip. During its "year,” the heat and light it receives from the Sun ranges from 0.1% and 0.04% of what we receive on Earth. This means Pluto is cold, with temperatures ranging from -220 C in summer to -240 C in winter.

Forthcoming spacesuits will be a boon to all future moon explorers, both male and female, NASA officials say.
The spacesuit that will be used by NASA's Artemis program, which aims to return humans to the moon just a few years from now, will fit a wider range of body sizes, will be highly mobile and will be made of more modern materials compared with the Apollo surface spacesuits that preceded them in the
