![]() This data was last updated January 1, 2021. How many satellites orbit Earth?Īccording to the Union of Concerned Scientists, there are a total of 3,372 operational satellites currently orbiting Earth. 22, 2020 - to avoid potential collision with unidentified objects.Īs orbits around Earth get more and more crowded, this again opens up for debate around what we are doing about orbital debris and space traffic management. This is a significant and worrying development which comes on the back of three emergency maneuvers by the space station last year - the latest being on Sept. While utmost precautions are taken to reduce the potential for collisions with the space stations - objects softball-size and bigger are monitored for potential collision with the ISS in orbit - this apparently came from a piece of debris that was too small to be tracked. Thankfully, the functioning of the robotic arm is unaffected.Īccording to Canadian Space Agency (CSA), a routine inspection on May 12 discovered the damage. The agency's effort has focused on making sure new rockets and satellites burn up in Earth's orbit once they're no longer useable, rather than careening uncontrollably around Earth.A piece of orbital debris recently hit Canadarm2, the nearly 18-meter-long robotic arm on the International Space Station that helps with maintenance tasks and “catches” visiting spacecraft. A January report from the NASA Office of the Inspector General found NASA's effort to stopping adding debris to Earth's orbit was "not sufficient" to prevent cascading collisions in space. Meanwhile, US rocket parts and dead satellites from the '90s continue to orbit Earth. Other notable space junk offenders include India and China, which have each blown up satellites in space. NASA Administrator Bill Nelson criticized Russia for its missile test on November 15, calling it "irresponsible," "reckless," and "dangerous."īut the US has created thousands of bits of space debris orbiting Earth - including the rocket chunk that menaced the ISS on Friday and debris from a 2008 missile strike that destroyed an aging reconnaissance satellite. NASA isn't cleaning up its old space junk This week, Elon Musk said SpaceX changed the orbit of some of its Starlink satellites in order to avoid debris. Space junk is also a problem for private companies. In 2020, the orbiting laboratory had to dodge debris on three occasions.Ī LeoLabs dashboard shows more than 200 pieces of debris the company is tracking from Russia's anti-satellite missile test, as of December 3, 2021. Friday marked the second time the ISS had to change course in order to avoid debris this year, including once last month, when Russia swerved the station away from a piece of junk. The two-and-a-half-minute engine burn lowered the space station's altitude by 310 meters - about 1,000 feet - setting it on a new path, safely out of reach of the rocket chunk.īecause predicting the path of debris in Earth's orbit isn't exact, mission controllers routinely move the ISS when objects are expected to pass close by. ![]() ET, Roscosmos fired the engines of its Progress cargo spacecraft, which was docked to the ISS, pushing the orbiting laboratory closer to Earth. NASA and Russia's space agency, Roscosmos, monitored the chunk throughout Monday, eventually deciding they needed to move the space station.Ībout two hours before the debris was set to pass the ISS, at 2:58 a.m. The International Space Station (ISS) changed course Friday to avoid a possible collision with a piece of an old Pegasus rocket.Ī chunk of that old rocket, which broke apart two years after the United States launched it into Earth's orbit in 1994, was on track to pass close to the ISS Friday morning. ![]() Account icon An icon in the shape of a person's head and shoulders.
