As many as 900,000 hazardous pieces of space junk are presently circling around the Earth. Japanese companies are testing innovative solutions to eradicate the threat.
Fragments of man-made debris are currently orbiting the Earth at speeds of up to 8 kilometers (5 miles) per second, posing a serious hazard to satellites and even manned spacecraft, such as the International Space Station .
SpaceX Crew-2 Mission to Have International Theme
The next NASA-SpaceX crewed mission to the International Space Station, scheduled for later this month, is taking on a true international theme.
Global partnerships, and work being done in orbit, is setting the tone for future human missions to deep space.
Dr. Don Platt , an associate professor of space systems at the Florida Institute of Technology in Melbourne, Florida, says that's why sharing the expense among many nations is key.
Heads up! Small asteroid to pass very close on Monday | Space | EarthSky
Small asteroid 2021 GW4 will pass extremely close to Earth on Monday, April 12, 2021. It’ll pass just 12,313 miles (19,816 km) from Earth’s surface, or about 5% the Earth-moon distance. Amateur astronomers using telescopes can see it passing the galaxy Messier 95 on the night of Sunday, April 11.

A recently detected space rock will pass by our planet on Monday, April 12, 2021. It’ll come extremely close, far closer than geostationary satellites orbiting some 22,000 miles (35,786 km) above Earth. The small asteroid has been designated as 2021 GW4. It is estimated to be about 16 feet (5 meters) in diameter. It’s a small space rock, and there’s no risk of impact, astronomers say.
SpaceX Starlink beta: What it is and when you can get it - TechRepublic
But why pack dozens of satellites onto a launch vehicle and blast these units into space rather than say burying miles of fiber and constructing towers on Earth? The answer is a complex grab bag of basic supply-and-demand economics and business solvency considered alongside emergent technologies in a burgeoning market.
From remote Canadian villages to sub-Saharan Africa and polar regions, Bill Menezes, director analyst with Gartner Research, said the cost of extending traditional terrestrial broadband networks to these remote areas is "huge."

Star Points: Signs of sunspot cycle returning to normal - Carroll County Times
Astronomers have charted the sun's cycle of sunspot maximum and minimum for hundreds of years. The roughly 11-year cycle includes a maximum as the number of dark visible sunspots crescendos followed by a diminishing number of spots leading to the cycle minimum.
In the most recently completed cycle, the number of sunspots noticeably diminished. The cycle's sunspot maximum was the lowest since the opening decade of the 20th century. Another of the cycle's statistics, the average daily sunspot count was the lowest since this statistic started being tracked in the mid-1800s.
Stunning images of Mars keep coming 15 years since HiRISE camera first orbited » Borneo
THE WASHINGTON POST – Images of Mars from the past decade have shown amazing craters, dust storms and colourful mineral deposits. The photos come from the most powerful camera ever sent to a planet. It's called High Resolution Imaging Science Experiment, or HiRISE, and it's helping scientists understand the planet where NASA has sent rovers and where it may send humans.
Launched in 2005, the camera was designed to take detailed photos while orbiting the Red Planet. HiRISE has transmitted nearly 69,000 images since 2006 and is still sending pictures. The images are colour-enhanced to allow scientists to see important details their eyes could not ordinarily detect.
Tiny Astroscale satellite will test space junk cleanup tech with magnets | Space
Astroscale just launched the first commercial space junk cleanup mission designed to locate and retrieve used satellites and other debris orbiting Earth.
The ELSA-d mission will test new technology developed by Astroscale, which consists of two satellites stacked together: a 385-lb. (175 kilograms) "servicer" and a 37-lb. (17 kg) "client." The servicer is designed to safely remove debris from orbit, while the client spacecraft will serve during the demonstration as a piece of debris to be cleaned up. Once the two satellites separate, they will perform a cosmic game of cat and mouse over the next six months.
