Space Debries

1.  Space Debris is a mix of either old or
useless satellites in space.
 Space debris is also known as orbital
debris, space junk, space waste, space
trash, space litter or space garbage.
 The debris has actually made a “debris zone around
the sphere. “When we go to the moon, or Mars, we
have to go through this debris band.

3. Amount of Debries:
There are more than 500,000 pieces of junk floating around Earth’s
orbit,
 including defunct satellites,
 rocket boosters,
 nuts and bolts,
all of which pose a substantial threat to astronauts and
spacecraft, according to U.S. space agency NASA. The European
Space Agency said that as of January 2018,
 there are about 29,000 objects larger than 10 centimeters,
 around 750,000 objects that range between 1 cm to 10 cm and
 about 166 million objects between 1 millimeter to 1 cm in size.

4.  There are 1100 active satellites
 There are about 2,600 ones that no longer
work.
Russia launched the first satellite,
Sputnik 1, in 1957. The oldest one still in
orbit, which is no longer functioning.

5. According to UNOOSA 81 countries have launched
satellites, although this is slightly complicated by the fact that
satellites are also launched by institutions and organisations such as
the European Space Agency.
In terms of countries with the most satellites
launched between 1966 and 2016
 USA significantly leads the way with 859
satellites,
 China is second with 250
 Russia third with 146
 These are then followed by Japan (72)
 India (55)
 UK (52).

6. Purposes of the satellites are:
Communications: 792 satellites
Earth observation: 661 satellites
Technology development/demonstration: 213
satellites
Navigation/Positioning: 121 satellites
Space science/observation: 76 satellites

7.  NASA says that on average, one piece of junk falls to Earth
every day.
 There is still no concrete solution to getting rid of
it.
 Satellites that fly below a certain height are
supposed to be put in an orbit that will make them
fall to Earth and burn it.
 At high altitudes, they are to be boosted up to still
higher orbits to get them out of the way.
Solution:
Old satellites can pose a risk for collisions with active ones, so
there are rules and recommendations to avoid a buildup of junk in
space.

8. Now it’s clear that very soon, we will
need to start removing this debris from
our atmosphere or the consequences will
be serious.
