Scientists Impaled Space Junk With a Harpoon, Here’s Why That Matters
Space junk threatens to entomb Earth in an artificial bubble, but promising solutions for cleaning up our trash are on the horizon. Watch More Space Crafts! | https://bit.ly/2GqH0aO Read More:
The Space Junk Problem Is About To Get A Whole Lot Gnarlier
“Space junk is the colloquial name for orbital bits that do nothing useful: spent rockets, fragments splayed by collisions and degradation, old satellites no one cares about anymore. In total, they amount to millions of pieces of debris, many of which are large enough to seriously ding satellites and the International Space Station.” The quest to conquer Earth’s space junk problem
“Zombie satellites, rocket shards and collision debris are creating major traffic risks in orbits around the planet.” A satellite with a harpoon, net and drag sail to capture space junk is in orbit and will be tested soon
"The purpose of the RemoveDebris spacecraft is to demonstrate the effectiveness of debris nets and harpoons at capturing and removing space debris from orbit." ____________________ Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.

What is RemoveDEBRIS mission and how it operates?
The RemoveDEBRIS mission will perform a number of active space debris removal technology demonstrations, testing novel technologies, representative of an operational scenario during a low-cost mission.
SSTL has designed and manufactured the Remove Debris satellite platform, which hosts the payloads for use in the debris removal demonstrations. These payloads, or technical content within them, have been produced by mission partners Airbus, ArianeGroup, CSEM, Inria, ISIS, SSC, and Stellenbosch University.
This Satellite Net Is Cleaning Up Space Junk
Space junk is increasingly becoming a big problem for the future of spaceflight, but RemoveDEBRIS is trying to come up with a solution. During a cleanup test that took place in September, the project, led by the University of Surrey, successfully deployed a net which captured a piece of debris that was orbiting around Earth. ► Subscribe for more tech & culture videos: http://on.mash.to/subscribe ◄

Space Debris: How much junk is in Space? - BBC What's New?
We've all heard about how important it is to not litter and to recycle our waste at home. Now there are concerns about the amount of rubbish floating around in Space! We rely on satellites for things like mobile phones, TV and GPS, but as more of them are launched the risk of space debris increases. Now, scientists at the Surrey Space Centre in the UK have invented a new way of cleaning it up.
A net successfully captured space junk
The net and its satellite are designed to capture debris orbiting the Earth. Learn more about this story at https://www.newsy.com/83664/ Find more videos like this at https://www.newsy.com Follow Newsy on Facebook: https://www.facebook.com/newsyvideos

Why These Lasers Are Too Powerful to Use in Space
Many countries have proposed developing giant lasers to shoot space junk into such tiny pieces so that they will no longer pose a threat to important spacecraft like the International Space Station. But, are space lasers really a thing?

NASA Studies Laser for Removing Space Junk
“Kessler pointed out that when the rate at which debris forms is faster than the rate at which it de-orbits, then the Earth would become surrounded by permanent belts of junk, a scenario now known as the Kessler syndrome.” Trash-Blasting Lasers Could Help Clean Up Space Junk, China Says
“China's willingness to experiment with rapid debris removal is appropriate considering that the country is considered one of the worst offenders when it comes to space junk, Universe Today reported. In 2007, a Chinese anti-satellite missile test was responsible for what is considered the most severe fragmentation of space junk in history.” China has a plan to clean up space junk with lasers
“For the sake of their study, the team conducted numerical simulations to see if an orbital station with a high-powered pulsed laser could make a dent in orbital debris. Based on their assessments of the velocity and trajectories of space junk, they found that an orbiting laser that had the same right ascension of ascending node (RAAN) as the debris itself would be effective at removing it.“ ____________________ Seeker explains every aspect of our world through a lens of science, inspiring a new generation of curious minds who want to know how today’s discoveries in science, math, engineering and technology are impacting our lives, and shaping our future.

This 19-year-old can keep astronauts safe from space junk
Space debris is a growing threat to space exploration. Subscribe to our channel! http://goo.gl/0bsAjO When 15-year-old Amber Yang first heard about space trash it gave her nightmares. How could such an imminent threat to space exploration be left on the back burner? After seeing videos with astronaut Scott Kelly, she decided to take matters into her own hands. Within a few years she consumed all the media she could on space debris, taught herself to code, and learned the ins and outs of astrophysics. By 18 she had developed an AI-based space debris tracking program that she claims is one of the most accurate in the world.

Space debris - efforts to clean up space
The European Space Agency (ESA) is part of an international effort to monitor and – ultimately – tackle space debris. This junk – accumulated in orbit since the dawn of the space age sixty years ago – poses an increasing risk to operational spacecraft. ESA is developing missions to tackle the problem to help prevent a serious collision in space. The Agency is also monitoring possible dangers caused by fragments of redundant spacecraft falling to Earth, such as China’s space station Tiangong-1 – due to enter the atmosphere in the coming months. Visit our Clean Space site to learn more: http://www.esa.int/Our_Activities/Space_Engineering_Technology/Clean_Space
Satellite Might Be The Solution To Space Junk
There is an estimated 7,000 tons of junk orbiting the Earth. The Surray Space Center wants to clean it up, so they designed a satellite called RemoveDebris. It will test cheap methods of picking up litter in space. The satellite will go up into space and deploy artificial space junk. It can use nets or harpoons to capture the junk. Finally, the satellite will enter Earth's atmosphere and while it's dragged down the junk will burn up. Where does space debris come from? Debris comes from old bits of rocket, disused satellites, or debris from collusions. Space debris is a major threat to space assets. The Internet, GPS, and weather tracking all use satellites and RemoveDebris could keep them same from junk.

Space Junk: A Traffic Crisis in Outer Space?
Jonathan McDowell, CfA, Astrophysicist with Chandra X-Ray Observatory It's been 60 years since the launch of the first artificial satellite, Sputnik, and space is getting busier and busier. There are over 1,500 working satellites up there, but there are also over 17,000 known pieces of orbital debris whizzing around at up to 18,000 miles an hour. McDowell will talk about the demographics of the satellite population: who is putting satellites up there, what are they doing, what the space junk is and why there's so much of it - and what can we do about it?

Space junk: Brane Craft to clean up floating debris around Earth's orbit - TomoNews
EL SEGUNDO, CALIFORNIA — NASA has awarded $500,000 for the development of an innovative new spacecraft that promises to get rid of orbital trash. According to a press release from the Aerospace Corporation, space debris in the form of spent rocket parts, old satellites, shrapnel and other items are accumulating around Earth's orbit, which may make collisions more common. To address this issue, NASA is looking to Aerospace's Brane Craft, a light, 3 foot-by-3 foot spacecraft that's thinner than human hair. When deployed, the Brane Craft moves toward a piece of debris and wraps itself around the item. It then fires its thrusters and pushes back toward the Earth. The spacecraft eventually lowers itself and the debris down to the atmosphere, where both are incinerated. The Brane Craft is intended to be light and cheap enough that it can be sacrificed at the end of a cleaning mission. But it may also have other applications beyond just collecting trash. The spacecraft is extremely fuel-efficient, making it fully capable of travelling long distances, perhaps to explore and mine asteroids or other space rocks.

Will space junk end our modern way of life ? - The Kessler Syndrome
Space aint what it used to be, mainly because just like here on the earth, we are slowly filling the most important part just above us, with junk. You can now translate this and other curious droid videos, see my video about it here https://www.youtube.com/watch?v=xLPVgIytKyg After sixty years of space travel, flight debris, or space junk, has accumulated round the Earth, to the point that it’s becoming dangerous. With the amount of junk in orbit expected to triple within the next fifteen years, experts are beginning to take the problem very seriously indeed. footage of Space Junk animation courtesy of ESA.

The amount of space junk around Earth has hit a critical point
There are almost 30,000 man-made objects orbiting Earth. Many are tiny pieces of rockets and satellites, while others are completely dead satellites not in use anymore. All of them pose risks to other spacecraft and satellites — and as access to space becomes more affordable, the risk of a chain reaction of satellites crashing into one another will continue to increase.

Space debris - a journey to Earth
Space debris - a journey to Earth takes the audience on a journey from the outer solar system back to our home planet. The objects encountered along the way are manmade. Originally designed to explore the universe, these are now a challenge for modern space flight. An estimated number of 700,000 objects larger than 1 cm and 170 million objects larger than 1mm are expected to reside in Earth orbits. The video gives a closer look at the different regions used for space flight and explains how mitigation and removal measures could preserve future usage of these orbits. Produced for the 7th European Conference on Space Debris, 18-21 April 2017.

Dealing with space debris
Earth is surrounded by a cloud of space debris. This material ranges from dead satellites and rocket stages to fragments of material and even flecks of paint… and all this junk could do enormous damage to working satellites. During 18–21 April, experts from around the world will meet at ESA’s European Space Operations Centre, Darmstadt, Germany for the 7th European Conference on Space Debris. Delegates will discuss the extent of the debris problem and what can be done to ensure that satellites we rely on – providing us with services such as navigation, TV and weather forecasting – can operate safely in the future. Talks will address acute issues like current practices in debris avoidance, novel concepts for removing debris, and the deployment of large constellations of several thousand satellites for telecommunications. The conference will be opened by ESA Director General Jan Woerner and NASA’s former orbital debris chief scientist, Donald Kessler. On 18 April and 21 April, live webcasts will cover the keynote address and press briefing, respectively. Details via esa.int/debris. More information

Space debris story (2013)
The story of space debris highlighting how the unintended consequences of intense spaceflight activity during the past 60 years has resulted in a growing population of debris objects that pose hazards to safe space navigation. In 2013, experts estimate that 29 000 objects larger than 10 cm were orbiting Earth. The video also highlights the current state of debris mitigation measures and presents several concepts for removing defunct satellites from economically vital orbits now being studied by space agencies and industry across Europe. This video was produced for the 6th European Conference on Space Debris, 22-25 April 2013.

Bringing the debris back is easy, however, on reflection I should have probably added more parachutes, since the landing speed was close to destroying the module.

How To Clean Up Space Junk
Space junk is a real problem. NASA now tracks around 20,000 pieces of debris orbiting Earth, most of them larger than 10cm across. Since the average speed of a collision between orbiting objects is 10 km/s these pieces of trash can cause a lot of damage despite their small size. Scientists in Switzerland have a plan to clean up space junk - it involves creating a 'Janitor Satellite' that will seek out pieces of space junk to drag back into the atmosphere causing them to burn up.

ORBITAL DEBRIS SAFELY PASSES INTERNATIONAL SPACE STATION
A small piece of Cosmos 2251 satellite debris safely passed by the International Space Station at 2:38a.m. EDT, Saturday March 24 allowing the six Expedition 30 crew members onboard the orbiting complex to exit their Soyuz spacecraft and resume normal activities. The crew sheltered in the two Soyuz spacecraft as a precaution, the third time in station history that a crew has had to shelter in place due to the possibility of a conjunction with orbital debris and the first since June 2011. NASA's Expedition 30 Commander Dan Burbank and Russian cosmonauts Anton Shkaplerov and Anatoly Ivanishin were in their Soyuz TMA-22 spacecraft attached to the Poisk module on the space-facing side of the Zvezda service module, while cosmonaut Oleg Kononenko, NASA's Don Pettit and Andre Kuipers of the European Space Agency were in their Soyuz TMA-03M spacecraft on the Earth-facing side of the Zarya module. The piece of debris was a remnant of a Feb. 10, 2009 collision between the dormant Cosmos 2251 satellite and an operational Iridium 33 communications satellite. The collision added about 2,000 trackable items to the orbital debris catalog. At the time of closest approach, the debris was moving from left to right in front of the station at an estimated overall miss distance of between 11 and 14 kilometers and a radial miss distance of 120 meters.
