Abandoned artificial satellites. Tanks jettisoned from shuttles. Refuse generated during space station construction. This junk, space debris, is traveling around the Earth at speeds approaching 8 km/s. This is a story of 2075, a time in which this space garbage has become a serious problem.
This is Planetes
, a near-future hard sci-fi story that focuses on a small group of debris collectors who are part of a larger company. Both the original manga
and the anime adaptation
set small personal stories and dramas in the realistic context of near-future space exploration, complete with radiation sickness
, impacts of growing up on the moon
, and of course, the dangers of space debris
. The reality of the show is emphasized by a recent JAXA presentation was titled PLANETES could be a true story?: Instability of the current debris population in LEO
, and the English DVDs include interviews with NASA staff who work on assessing orbital debris
After nearly 5000 launches, we've put a lot
of objects in space
. Amongst them are around half a million pieces of debris, generated by explosions, breakups and collisions
). With speeds of up to 15 km/s, even tiny fragments can cause major damage
and the creation of further debris. The Kessler Syndrome
describes a situation where the cascade of collisions creates an exponential increase in the amount of debris, leading to a potentially impassable artificial belt in LEO lasting for generations

Dr Alice Gorman
is on a mission
(pdf) to preserve our heritage items in space. Plans to clean space junk
orbiting Earth could result in the loss of irreplaceable historical artefacts
warns. Among the items that should recognised for their heritage value are the Vanguard One
satellite, launched in 1958 and the oldest human object in space
. Preserving items like these could provide evidence of a nation's presence in space or help reconstruct a history of space exploration
Discovery-Alpha dodge astronaut's space junk.
Do we as a people know how to pollute, or what? A 1999 study estimated there are some 4 million pounds of space junk in low-Earth orbit.
I just watched a program on The Learning Channel
that also showed how the Cosmonaunts on Mir would simply jettison their waste into space...traveling 18,000 MPH!!! And I thought flipping a cigarette butt out the car window was bad....
