    Space Travel Could Become Impossible In The Future – Unless We Clean It Up
    posted by Kevin Webster April 29, 2017

    A few weeks ago, I was simply browsing through my daily science briefing, my news feed and multiple messengers instantly started buzzing with news articles regarding a new world record. India had launched a total of 104 satellites onboard a single rocket into space, breaking the previous record of Russia of launching 37 satellites in 2014. I took a deep, long breath and inadvertently uttered ‘No! not again!’ Don’t get me wrong, I am a great space enthusiast and every single space discovery leaves me with awe and elation, however launching satellites into earth’s orbit carries a whole different emotional value for me – and for planet earth’s future for that matter.

    Listening to the countdown and then seeing a rocket spewing out those thick milky clouds of rocket fuel, burning and pushing this marvel of human engineering and ingenuity up, cutting through the clouds and our atmosphere, straight into space; has been mesmerising generations since the Russian launch of Sputnik. However, somewhere between hundreds of rocket launches and ever evolving technological advancement – courtesy of the satellites that we so proudly shoot out into space – we have stopped looking into the inevitable consequence of ‘Space Junk’.



    Our planet has now turned into a ‘beehive’ of countless satellites, some performing service (or surveillance depending on your preference) to humanity, while others obscured and abandoned, orbiting around the Earth and have now become a real cause of concern for space engineers and even astronauts. The problem has become such a colossal issue that NASA has a dedicated page where you can actually witness for yourself, the extent of the space litter engulfing earth; which is truly shocking, to say the least.

    According to NASA, the space around the earth is littered with all kinds of space debris ranging from ‘flecks of paints’ to full-size satellites that are no longer functional and are abandoned by the host country. Most of the space junk is orbiting around the earth at a staggering speed of almost seven times the speed of a bullet. These rogue objects reach the speed of approximately 18,000 miles per hour, posing an ever-present threat to astronauts and vital space equipment onboard the International Space Station.To have an idea of the extent of damage that a half an inch piece of debris could cause moving at six miles per second, imagine getting smashed in the head by a bowling ball moving at 300 miles per hour; which is 100 miles more than the average speed of a Boeing 737 taking off.

    According to the renowned American astrophysicist and director of the Hayden Planetarium, Neil deGrasse Tyson, the future of space travel is in great jeopardy due to the space debris. Tyson propounded in an interview that it will become increasingly challenging for launching successful space probes and other missions if we keep on littering our space with satellites and other junk. While speaking to comedian Joe Rogen in his podcast Joe Rogen Experience, Tyson carefully criticised humanity’s ambition to colonise other planets citing that our behaviour about our earth is enough to predict what we are capable of in terms of destroying our planet and its immediate vicinity.

    space travel....like the moon landings that we cant repeat for 50 years and counting....

    brought to you by the same people that produced 'peak oil' 'free trade' 'they hate us for our freedoms' 'pancake theory' 'those are contrails' 'globalist warming' 'peak water' 'swine flu hysteria' 'bin laden raid' sandy hoax'

    you made the mess, you clean it up. whoever put that crap up there should have to clean it up - including bankruptcy/asset selling to fund it. this includes the personal assets of those in charge of the govs/corps that did it

    There is a river that runs from here through CT that people have been trying to get GE to clean up. Luckily, there ar some very determined residents.

    Wonder how much free Gold/Silver is floating around up there. Someone here is gotta have a "GIM9000 Interstellar Metals Recovery Module" in their garage.

    3 things ... first off, DeGrass is a mouthpiece first and foremost. Take nothing he says at face value. Second, space travel isn't in any danger ... The Nasa map shows paint flecks as the size of a city. The amount of space concerned is vast and the odds of a random collision miniscule. The problem is that the desirable orbits are like highways .. everyone ends up in the same lane going the same way. That is their real concern. And 3rd .. efforts are already underway to reduce the amount of space junk ... and none of those efforts have Nasa to thank. From SpaceX and Blue Origin developing real reusable rockets and space capsules, to satellites being decommissioned and deorbited by their owners before they run out of juice, to capture and deorbit tech that can be sent after junk that's moving into a populated orbit.

    The problem is well documented. Stopping the militaries of the world from making it worse is the real unaddressed issue.

    a lot of the junk up there is softball size or less.

    Yep, and it's the "less" ya gotta worry about. A fleck of paint nearly took out a space shuttle. Had it been much bigger, it would have. In fact, several windows have had to be replaced during the program just because of paint flecks hitting them. The tiles would oftentimes get tore up too.

    Supposedly they can track anything bigger than about 2 inches in diameter in low Earth orbit and about 3 feet in geostationary orbit.

    Look at the pic in this link of the damage caused by something 1mm in size. https://qz.com/773511/photos-this-i...debris-traveling-at-incredible-speeds-can-do/ If that hit someone out for a space walk, it'd punch a hole right through 'em.


    The answer is to not launch any more sats that do not have the means to deorbit built in.

    That's less the problem than the ones that conk out before they can use the deorbit ... which all long duration sats already have in the form of stabilizing thrusters. The biggest out of control sat at the moment is the nearly new chinese space station that they lost control of earlier this year and they have no way to deal with, and no idea where it's going to come down, or even when (beyond a very general frame of weeks). This, and of course, sats that just randomly self destruct as a dark sat goes past near them.
