A rocket set to slam into the moon next month, initially identified as
belonging to SpaceX, has now been identified as a Chinese rocket.
Last month, an amateur astronomer, Bill Gray, suggested the rogue object was
likely a spent SpaceX Falcon 9 rocket from a 2015 launch and was going to
collide into the Moon on 4 March.
He now believes the object is not a SpaceX Falcon 9 part, but an old Chinese
rocket instead.
Bill Gray who has been tracking asteroids as part of Project Pluto, has been
following this space object since March of 2015.
The object was first picked up by the Catalina Sky Survey, a program that
uses telescopes near Tucson, Arizona to scan the sky for potentially
dangerous asteroids that could pose a threat to Earth.
But unlike a typical asteroid, astronomers noticed that this object wasn’t
orbiting the sun but was actually orbiting the Earth, suggesting that it was
manmade space junk.
Gray and others mistakenly thought the object was the top portion of a
SpaceX Falcon 9 rocket that had launched in February 2015.
However, Gray admits that identifying space objects can be tricky. ‘I had
pretty good circumstantial evidence for the identification, but nothing
conclusive,’
Gray wrote
in a new blog post, first reported by
Ars Technica.
A closer look at the object’s history and additional information from Nasa
has now convinced Gray that the object is a leftover piece of a Chinese
rocket from one of China’s moon missions.
Gray was alerted by Jon Giorgini, an engineer at Nasa’s Jet Propulsion
Laboratory, who keeps track of active space missions, that it was unlikely
that the object was a SpaceX rocket part.
On closer examination, they found that China’s Chang’e 5-T1 mission,
launched in October 2014 is now the best guess for this mystery object.
China is notorious for releasing very little information about its space
missions.
In December, Elon Musk’s Starlink satellites nearly collided with the
Chinese Space Station twice this year. The close calls led to criticism of
Musk’s internet satellite company, Starlink.
Despite the confusion about the object’s identity, Gray says this is just
further proof we need more information about rocket boosters that go to deep
space. As of now, no formal entity tracks leftover rockets that go into deep
space trajectories.
Gray told tech site
The Verge
that it would be better if those who launch deep space rockets had to report
the last known location of their vehicles, to make it easier to track and
identify the lost parts.
The rogue rocket booster poses no threat when it’s supposed to collide with
the moon’s surface next month. It’s expected to crash into a crater on the
far side of the moon known as Hertzsprung.
While there’s no way to watch the crash take place, future moon orbiting
spacecraft might be able to get a glimpse of the impact.

I wonder if all the dimwits who piled on to Elon Musk when this was initially reported as as part of Falcon 9 will now direct their harsh criticism at China.
ReplyDeleteNah, probably not.
