Tiny bursts of electrical energy caused by collisions of objects no wider than a pencil lead could one day allow pieces of space debris smaller than one millimeter in diameter to be tracked, reducing the danger to spacecraft in Earth orbit.Continue Rea… Continue reading Tiny sparks from collisions may enable tracking of tiny space debris
Believed to be caused by a mix of genetic and environmental factors, Parkinson’s disease is a chronic, progressive disease that affects the central nervous system, particularly the motor system, resulting in tremors, rigidity, and difficulty walking. New research has found that a gene associated with an increased risk of Parkinson’s disease also contributes to one of the hallmarks of the disease.

SpaceX has lost up to 40 satellites of its Starlink internet constellation due to a geomagnetic storm that is knocking them out of orbit. The satellites were part of a batch of 49 that were launched on February 3 and had not reached their operational a… Continue reading Solar storm deorbits up to 40 of SpaceX’s Starlink satellites
Marine debris is a huge problem, both when it’s floating at sea and when it gets washed up on the shore. In order to locate the latter for removal, scientists are now developing artificially intelligent drones which will spot human-made beach trash fro… Continue reading AI-enabled drones will tell human teams where to find marine debris
On a dark night in 2006 I was bicycle commuting to my office, oblivious to the countless man made objects orbiting in the sky above me at thousands of miles …read more Continue reading Space Age Road Rage: Right Of Way Above The Karman Line
Purdue University engineers have developed a space-debris-clearing drag sail called Spinnaker3 that is designed to speed up the deorbiting of space junk up to 400 miles (645 km) high so it safely burns up in the Earth’s atmosphere. The sail will be put… Continue reading Space-junk sail to help deorbit its own launch vehicle
Private orbital debris removal company Astroscale has validated its magnetic capture system that is designed to tackle the problem of space debris. Its End-of-Life Services by Astroscale-demonstration (ELSA-d) servicer satellite managed to capture a si… Continue reading ELSA-d spacecraft captures “space debris” in orbit for the first time
Satellite-threatening debris in high-Earth orbit is not being tracked closely enough, according to the results of a newly published survey. Probes orbiting in geosynchronous orbit – a region of space roughly 36,000 km (22,370 mi) above our planet’s sur… Continue reading Over 75% of space debris detected in new survey is unknown objects
A team of ESA scientists has developed a way to use lasers to accurately track space debris even in broad daylight. Using a combination of special telescopes, detectors, and light filters tuned to specific wavelengths, it’s now possible to increase the… Continue reading Upping the contrast enables daytime laser tracking of space debris
The buildup of space debris is a serious problem that won’t be going away anytime soon, with thousands of pieces of junk currently in orbit around the Earth. A team of researchers has put forward a novel way to keep things in check, making a case for c… Continue reading Could orbital fees force satellite operators to deal with space junk?
