- 4174 - SPACE JUNK - orbiting Earth. Space junk orbiting around earth pollution around our planet. A Russian satellite has broken into pieces, littering debris in space. Russian KOSMOS 2499 satellite broke up. They are tracking 85 individual pieces of debris at an altitude of 726 miles. The breakup started on January 4, 2023.
--------------------- 4174 - SPACE JUNK - orbiting Earth
- At the high
altitudes, it will take decades for the space junk debris to deorbit and burn
up in the Earth’s atmosphere, and presence of this debris in an increasingly
busy region in Earth orbit.
-
- This satellite has
had a curious history. Russia quietly launched KOSMOS 2499 on May 23, 2014. But
tracking indicated the satellite performed unusual maneuvers, leading some to
speculate that it may be an experimental anti-satellite weapon, satellite
maintenance vehicle, or collector of space debris. The satellite was designed to test
experimental plasma propulsion engines/ion thrusters.
-
- Both the first and
now second breakup event was thought to be caused by an explosion of that
propulsion system. Analysis points
toward a low intensity explosion, due to the asymmetry of the debris cloud,
magnitude of the velocity imparted to the fragments, and a known energetic
source on board ( the propulsion system).
-
- This event follows
a close call where two pieces of leftover Soviet-era space junk passed within
feet of each other on January 27, 2023. A piece of a rocket stage came as close
as 19.7 feet from a defunct satellite at an altitude of 611 miles above Earth’s
surface.
-
- NASA captured an
image of a mysterious black object orbiting the Earth in 1998, during the first
Space Shuttle mission to the International Space Station (ISS). The space agency refers to the strange entity
as item “STS088-724-66” in its catalog of space junk floating in low-Earth
orbit (within 1,200 miles).
-
- Jerry Ross, an
astronaut who took part in that mission, says that the object is a wayward
thermal blanket that broke loose while his team tried to attach an American
module to a Russian module on the ISS. But for a small, devoted following, it’s
a 13,000-year-old, artificially made satellite known as the Black Knight
satellite.
-
- Black Knight truthers
cite this as the first sign of their satellite, which sent the radio pulses.
Scientists have since determined that those radio pulses were most likely
naturally occurring signals that space objects emit while in orbit. The
prevailing theory, while still unlikely, is that Tesla heard a pulsar, or a
faraway celestial body that emits regular pulses of radio waves.
-
- One more bit of
disjointed speculation: In 1960, TIME published a story noting that the U.S.
Navy had detected an unidentified satellite that may have been a piece of
Soviet spy technology. It turned out to be a broken-off piece of the Discoverer
5, an early U.S. photo reconnaissance (spy) satellite, but believers still
point to this as definitive proof.
