Source of Hazardous High-Energy Particles Located in Sun - Tasnim News Agency

(Tasnim) – The source of potentially hazardous solar particles, released from the Sun at high speed during storms in its outer atmosphere, has been located for the first time by researchers at UCL and George Mason University.

Dead Russian satellite and discarded Chinese rocket are at ‘very high risk’ of colliding in orbit

An out-of-commission Russian satellite and a discarded Chinese rocket orbiting the Earth more than 600 miles above the surface have a ‘very high risk’ of colliding tonight.

Europe Launches Satellite to Start Space Junk Clean-Up Mission

European engineers launched a satellite to the International Space Station (ISS) on Monday to track space junk and take it back to the earth, kicking off the Remove Debris project.

‘Catastrophic avalanche of collisions’: Space junk can destroy satellites, scientists say

At least 170 million pieces of rapidly-moving space junk are now circulating in Earth’s orbit and this debris may even lead to a “catastrophic avalanche of collisions” and destroy all working satellites and even threaten economies, scientists said.

Space debris problem getting worse, say scientists

Scientists sounded the alarm Tuesday over the problems posed to space missions from orbital junk – the accumulating debris from mankind's six-decade exploration of the cosmos.

After 10 Years of Development, Japan Launches Space Junk Collector Into Orbit

On Friday night Japan launched an unmanned spaceship containing a ‘space junk collector’ bound for the International Space Station (ISS). The "Kounotori" (stork in Japanese) was attached to an H-IIB rocket and departed from Tanegashima Island in the Kagoshima Prefecture.

ISS performs evasive maneuver to dodge space debris

Russia’s Mission Control has corrected the orbit of the International Space Station to steer it clear of space debris.

A small Russian spacecraft in orbit appears to have been struck by remnants of a destroyed Chinese satellite. It’s just the second time in history that an active spacecraft has collided with an artificial object while in orbit.

Over 100 tons of space junk fell on Earth in 2014 (NASA)

More than 600 non-operating satellites, used-up stages of rockets and other pieces of space vehicles burnt last year reentering the atmosphere.

According to the American weekly newspaper Space News, the data was reported by NASA to the UN Committee on the peaceful uses of outer space, where the space junk disposition was discussed. 

Russia first among space junk producers (report)

Russia is occupying a confident first place as the producer of space rubbish orbiting the Earth, says a report published by the Central Research Institute of Mechanical Engineering, a subsidiary of the Russian Space Agency Roscosmos.

Of the 15,900 or so orbital objects classified as space junk, about 6.300 objects were left over by Russia, it says.

Defunct Soviet satellite plunges into Pacific (Russian Air Defense)

A defunct Soviet satellite has left the Earth's orbit, disintegrated and plunged into the Pacific as anticipated by the Russian Air Defense Forces, its spokesperson said Saturday.

"According to the Center for Space Monitoring at the Main Center for the Missile and Space Defense, the fragments of the space object left the orbit at 2:52 p.m. MSK [11:52 GMT] on November 8, 2014 over the Pacific Ocean," Col. Alexei Zolotukhin, a spokesperson for Russia's Aerospace Defense Forces said.

Περιπλανώμενα διαστημικά σκουπίδια απείλησαν τον Διαστημικό Σταθμό

Ο Διεθνής Διαστημικός Σταθμός (ISS) απειλήθηκε από περιπλανώμενα διαστημικά σκουπίδια την περασμένη εβδομάδα, αλλά το Αυτοματοποιημένο Όχημα Μεταφοράς (ATV) «Ζορζ Λεμέτρ» της ESA, το οποίο βρισκόταν συνδεμένο στον σταθμό, έσωσε την κατάσταση πυροδοτώντας τους προωθητήρες του και ωθώντας έτσι τον ISS και τους έξι επιβάτες του έξω από την πορεία των επικίνδυνων συντριμμιών.

Scientists develop new technique of orbiter defense from space debris

A new computer model that will help the scientists to increase orbiter defense from clashing with space junk has been developed in Ireland. The researchers from the country’s oldest university Trinity College reported that “new mathematical methods will help predict emergencies in terrestrial space”. 

According to one of the project initiators, Computer Science School Professor of Statistics, Simon Wilson, due to development in IT sphere they also managed to create new tools that will calculate more accurately impact points of satellite parts that didn’t burn in dense atmosphere.

Russian scientists develop system for monitoring space junk

Scientists from St. Petersburg Polytechnic University have developed a monitor system to follow space junk.

The system is a set of monitoring meters intended for a spaceship to ensure its safety if established on board, Rector of the St. Petersburg university Andrei Rudskoi told TASS on Thursday.

The space litter monitoring project aroused interest at the Russian Space Agency (Roscosmos). Chief of the Roscosmos agency Oleg Ostapenko has promised support to St. Petersburg Polytechnic University to enable it to test the litter monitoring meters on the orbit.
