A SPACEX ROCKET\u2019S upper stage is set to unintentionally crash into the Moon on Wednesday, a collision that poses no danger to Earth but will leave behind a lunar crater.<\/p>\n
It\u2019s understood that the stray piece of the SpaceX rocket has already made impact with the Moon.<\/p>\n
The crash, which was due to occur around 7.35am Irish time, will be confirmed by specialist telescopes monitoring the event.<\/p>\n
Images of the crash are not yet available due to a delay because none of the spacecraft orbiting the Moon were positioned to capture it live.<\/p>\n
Scientists will compare before-and-after pictures of the Moon\u2019s surface to spot the new lunar crater.<\/p>\n
\u201cIt might be possible for folks with a telescope to observe the plume of ejecta created by the impact,\u201d said Benjamin Fernando of Los Alamos National Laboratory in New Mexico, the lead author on a recent paper on the anticipated impact.<\/p>\n
\u201cIt is unclear how bright it will be, which is one of the reasons why we are looking to study this event,\u201d the researcher told AFP.<\/p>\n
Assuming all of the propellant is spent, authors of the paper estimate the spacecraft weighs around 4,000 kilograms.<\/p>\n
It is expected to slam into the Moon\u2019s Northern Hemisphere near the Einstein Crater, at some 8,690 kilometres per hour.<\/p>\n
\u201cThere is no danger to Earth,\u201d said Nasa spokesperson Jimi Russell\u00a0in a statement.<\/p>\n
\u201cNASA will continue to track the booster for training purposes, as well as later observe the impact site for scientific purposes.\u201d<\/p>\n
The Falcon 9 rocket took off last January, carrying two lunar landers. The booster returned to Earth, but the upper stage stayed in space to push the landers onward.<\/p>\n
Generally, for such \u201chigh-energy missions,\u201d SpaceX performs a manoeuvre to make sure the second stage \u201cis safe per the appropriate rules and regulations,\u201d said Julianna Scheiman, director of Nasa Science and Dragon Programs at SpaceX, at a Monday news conference.<\/p>\n
\u201cWe did that,\u201d she continued, but \u201cwhat has happened is essentially a mixture of solar activity and gravity forces have put it on a path towards the Moon.\u201d<\/p>\n
Like many scientists, Scheiman added that \u201cI also am very excited to see the observation.\u201d<\/p>\n
The paper authors encouraged both professional and amateur astronomers to attempt viewing or recording the collision.<\/p>\n
\u201cThis event provides an opportunity to test a pipeline for localising impacts on the lunar surface for future seismic experiments, investigating the dust and plume dynamics from impact events on the Moon, and considering hazards from artificial space debris impacts,\u201d wrote the research team.<\/p>\n
Nasa hopes to soon establish a sustained human presence on the Moon, making it critical to better understand space debris in lunar orbit.<\/p>\n
The Moon routinely weathers impact from space debris including meteoroids. Artificial collisions are less common.<\/p>\n
In the 1970s, the US space agency carried out deliberate crashes during its Apollo program to collect seismic data.<\/p>\n
