Watch the Video of a Spacecraft Landing on an Asteroid 300 Million Kilometers Away

Watch the moment a spacecraft lands on an asteroid some 300 million kilometers away.

An asteroid measuring approximately one kilometer in diameter called Ryugu (officially designated 162173 Ryugu) was visited by a spacecraft from Japan. In June 2018, JAXA’s (Japan Aerospace Exploration Agency) Hayabusa2 spacecraft arrived at the asteroid remaining in orbit around it and studying it.

But the mission as more than just studying an object 300 million kilometers away. Hayxabusa2 was tasked with mapping, exploring, and sampling the asteroid.

In February 2019, the spacecraft briefly touched down on the asteroi0d surface and fired a small projectile in order to expose subsurface soil and debris, and collect it with the spacecraft sampling horn. This object was completed, and the spacecraft returned to orbit.

Then, in July 2019, the spacecraft performed a second sampling from the asteroid’s subsurface. It fired a large copper projecting from an altitude of around 500 meters in order to expose pristine material. The projectile created a crater of around 20 meters in diameter, exposing the material.

In November 2019, the spacecraft was given commands to leave the orbit around Ryugu, and head back home with the materials it had collected.

Luckily for us, everything the spacecraft did while it was in orbit around the asteroid, and on its surface was photographed and captured on film. This means that we have the unprecedented opportunity of observing a spacecraft orbit and land on the surface of an asteroid located hundreds of millions of kilometers from Earth.

This recently released video reveals the fascinating journey of the Hayaabusa2 spacecraft, revealing mind-boggling details of the emission, and a rare view at the surface of a distant asteroid.,

The asteroid sampling mission was an unprecedented calling and allows scientists to peer into the history and geology of objects that formed in the early solar system. The recently revealed video shows the exact moments when the spacecraft lands on the asteroid, and collects the surface samples of the distant rocky body, in order to bring them back for further studies on Earth.

The few seconds that the spacecraft spent on the asteroid collecting the samples have helped astronomer get a better glimpse at the asteroid’s surface, helping experts understand its age and geological history. The touch-and-go moment has also helped scientists unravel a mystery about the odd color variations on Ryugu’s surface.

Observations of the asteroid’s surface revealed that Ryugu’s landscape was composed of two different types of material, clearly distinguishable in color. One of the materials was red, while the other one had slightly bluer tones. However, what exactly caused the color variations was something scientists could not predict.

The video of Hayabusa2 touching down on the asteroid was captured by the onboard cameras allowing us to see the sampling process in unprecedented details. The footage clearly reveals disturbances on the surface caused by the powerful thrusters of the spacecraft. It also shows how the spacecraft’s thrusters clear a coating of dark reddish material on the surface. The footage has helped scientists understand the composition of the asteroid.

Based on data so far, the new discovery possibly means that the material of reddish color on the asteroid may be a sort of suntan.

In other words, as Ryugu orbits the sun in an elliptical pathway, it turns towards the sun. During this brief rotation, the parts of the asteroid that point to the sun are struck with intense solar heat, which likely resulted in the red-colored material on its surface. So there you have it, evidence that even asteroids can get a sunburn.

Hayabusa2 it’s currently speeding towards Earth in order to deliver the precious payload it gathered from asteroid Ruyugu and is expected to arrive home in December 2020.
