Impact of Rocket Falls on Moon, Physics Experiment Explains Collision in Space All


KOMPAS.com – A rocket booster hit the lunar surface at nearly 6,000 mph on March 4. NASA scientists also studied the impact of rocket collisions that fell on the Moon with physics experiments.

Once the dust clears, NASA’s Lunar Reconnaissance Orbiter will shift into position to get a close-up view of the smoldering crater and hopefully shed light on the mysterious physics impact.

As scientists who study the moon, experts see the impact as an exciting opportunity. The surface of the moon is so cratered, it has recorded countless collisions over the last 4 billion years.

However, scientists rarely see asteroids or comets forming craters this month. Without knowing the specifics of what created the crater, there is little that scientists can learn.

Rocket collisions will provide experiments that can reveal a lot about how natural collisions hit and roam the planet’s surface.

A deeper understanding of collision physics will greatly help researchers interpret the moon’s barren landscape, including the impact they have on Earth and other planets.

Rocket falls to the moon

Launch SpaceMonday (28/3/2022) there is some debate about the exact identity of the object that fell on the collision course with the moon.

Astronomers know that this object is a booster discarded from satellite launches. The object is about 12 meters long and weighs almost 4,500 kilograms.

Evidence suggests this may be a SpaceX rocket launched in 2015 or a Chinese rocket launched in 2014, but both parties have disputed ownership.

The rocket is expected to crash into a vast barren plain inside the giant Hertzsprung crater, just above the horizon on the moon’s far side from Earth.

As soon as the rocket hits the surface of the moon, the shock wave will travel at a speed of several miles per second.

Within milliseconds, the rear end of the rocket’s hull will be obliterated with metal flakes exploding in all directions on the lunar surface.

The twin shockwaves will travel down into the powdery upper layer of the lunar surface called the regolith.

The compression of the impact would have heated up the dust and rock, producing a white-hot flash that would have been visible from space if any ships happened to be in the area at the time.

Clouds of vaporized rock and metal would expand from the point of impact as dust, and particles the size of sand would be flung into space.

Over the course of a few minutes, the ejected material will rain back onto the surface around the now-smoldering crater. Almost nothing was left of the ill-fated rocket.

However, because the crater of the LCROSS rocket is permanently obscured by shadow, my colleagues and I have struggled for a decade to determine the depth of this buried ice-rich layer.

Observing with the lunar reconnaissance orbiter

Experiments with these events provided the opportunity for scientists to observe very similar craters during the day. It will be like seeing the full LCROSS crater for the first time.

Because the collision occurred on the far side of the moon, it was not visible to Earth-based telescopes. But about two weeks after the impact, NASA’s Lunar Reconnaissance Orbiter is thought to have started seeing the crater as its orbit brought it above the impact zone.

Once the conditions are correct, the lunar orbiter’s camera will start taking photos of the impact site at a resolution of about one meter per pixel. Moon orbiters from other space agencies can also train their cameras in craters.

The shape of the crater and the ejected dust and rock will hopefully reveal how the rocket was directed at the time of impact.

A vertical orientation would result in more circular features, whereas an asymmetrical debris pattern might indicate more crater failure.

Models show the Moon’s craters could be about 10-30 meters in diameter and about 2-3 meters deep.

The amount of heat generated from the impact would also be valuable information.

If observations are made fast enough, it is possible that the lunar orbiter’s infrared instrument will be able to detect the hot glowing material in the crater.

This can be used to calculate the total amount of heat from the collision. If the orbiter can’t see fast enough, high-resolution images can be used to estimate the amount of melted material in the crater and debris field.

By comparing before and after images from the orbiter’s camera and heat sensors, scientists will look for other subtle changes in the surface. Some of these effects can extend to hundreds of times the radius of the crater.

Collisions and crater formation are widespread phenomena in the solar system.

Craters cracked and cracked the planet’s crust, gradually forming the loose granular top layer common in the world’s most airless. However, this whole physical process is poorly understood.

Observing the impending rocket impact and the resulting crater could help scientists better interpret data from the 2009 LCROSS experiment and produce better impact simulations.

Through a series of planned missions to visit the moon in the coming years, knowledge of the nature of the lunar surface, especially the amount and depth of buried ice, is in great demand.

Regardless of the rocket’s identity, this rare collision event will provide new insights that may prove critical to the success of future missions to the moon and beyond.
