Collision-free crossing in orbit of an old satellite and a piece of rocket – LEOLABS INC.
MADRID, 16 Oct. (EUROPA PRESS) –
The former Soviet satellite Cosmos-2004, launched in 1989, and a stage of the Chinese CZ-4C R / B rocket, launched in 2009, crossed over Antarctica avoiding the anticipated risk of collision.
The US company LeoLabs, which tracks the pieces of space junk, described as high the risk of collision of both objects, whose crossing was scheduled at 00.56 UTC on October 16 about 991 kilometers above Antarctica.
Subsequent calculations, however, lowered the probability of a collision to 10 percent and estimated the minimum distance between the two at the TCA at 12 meters, reports sputniknews.
“There is no indication of a collision. The CZ-4C R / B passed over LeoLabs’ Kiwi Space Radar (in New Zealand) 10 minutes after the TCA (closest approach time). Our data shows only one object, as we expected. , with no signs of fragments, “the company posted on its Twitter account.
Had they collided, they would have produced numerous new fragments and uncontrolled spacefaring over Earth’s orbit, a growing danger for the satellites in service and for the International Space Station itself.
