Rogue rocket about to smash into the moon is from China, not SpaceX, experts say

Ooooops!!

A rocket stage set to smash into the moon on March 4 is no longer believed to be a piece of a SpaceX Falcon 9 rocket, but rather a booster from a Chinese rocket sent to the moon in 2014, experts say.

Bill Gray, an astronomer and the developer of the asteroid tracking software Project Pluto, initially identified the errant space junk (which had been given the temporary name WE0913A) as the upper stage of a Falcon 9 rocket, predicting that the debris would collide with the moon after hurtling through space for seven years.

Gray now believes his initial assessment was wrong, and he has updated his blog post with a correction. The doomed object isn’t the SpaceX upper stage — launched in February 2015 to send the Deep Space Climate Observatory satellite, or DSCOVR, 930,000 miles (1.5 million kilometers) from Earth — but is actually a rocket booster from China’s 2014 Chang’e 5-T1 mission, which launched on October 2014, he said.

The object is set to hit the moon traveling at roughly 5,771 mph (9,288 km/h) on March 4.

Geomagnetic storm sends 40 SpaceX satellites plummeting to Earth

Elon Musk’s company launched a Falcon 9 rocket bearing the 49 satellites from Kennedy Space Center in Florida on Thursday (Feb. 3), but a geomagnetic storm that struck a day later sent the satellites plummeting back toward Earth, where they will burn up in the atmosphere.

“Unfortunately, the satellites deployed on Thursday were significantly impacted by a geomagnetic storm on Friday,” SpaceX said in a statement. “Preliminary analysis show[s] the increased drag at the low altitudes prevented the satellites from leaving safe mode to begin orbit-raising maneuvers, and up to 40 of the satellites will reenter or already have reentered the Earth’s atmosphere.”

The satellites were hit by the storm just one day after launch.[/s].

The Falcon 9 DSCOVR’s booster going to hit the Moon: a video — 7 Feb. 2022

The latest on some space debris…

The Falcon 9 DSCOVR’s booster: 7 Feb. 2022.

The animation above comes from 268, single, 4-second exposures, remotely taken with the “Elena” (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available at Virtual Telescope. The telescope tracked the apparent motion of the booster, so it looks like a sharp dot, with surrounding stars moving on the background. East is up, South on the left.

There was a VERY strong Moon interference, the booster was in the same spot of the sky as our natural satellite and grabbing it was quite hard. As we can see, the booster is blinking, as it is tumbling with a period of about 90 seconds.

New insight into blobs improves understanding of a universal process

Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have gained insight into a fundamental process found throughout the universe. They discovered that the magnetic fields threading through plasma, the charged state of matter composed of free electrons and atomic nuclei, can affect the coming together and violent snapping apart of the plasma’s magnetic field lines. This insight could help scientists predict the occurrence of coronal mass ejections, enormous burps of plasma from the sun that could threaten satellites and electrical grids on Earth.

The scientists focused on the role of guide fields, magnetic fields threading through blobs, or chunks, known as plasmoids. The guide fields add rigidity to the system and ultimately affect the ratio of large plasmoids to small ones and help determine how much reconnection occurs.

Plasmoid reconnection resembles the that occurs in smart phones or in high-powered computers that model the weather. During this computing, many processors are calculating simultaneously and making the overall calculation rate quicker. Similarly, plasmoids speed up the overall rate of reconnection by making it occur in many places at once.
