Hayabusa 2 returns with the first gas sample of an asteroid

Hayabusa 2 returns to earth with the asteroid gas samples

History created when Hayabusa 2 returns with the first gas sample of an asteroid – Dr. Foshimo.

We all are struggling with all the bad news throughout 2020 due to corona. But, humanity has achieved another milestone with the return of Hayabusa with the first gas samples of an Astroid. Human beings created history with this achievement.

What is Hayabusa 2

Do you remember Hayabusa2?

A unique spacecraft that was sent from Japan in 2015.

If no then let us tell you an interesting story and a mile stone achieved in astronomy and space research.

In 2014, Japanese scientists launched a satellite called Hayabusa 2 with a specific purpose that no one in the human history has done before.

The spacecraft was specifically sent to asteroid 162173 Ryugu to collect gas samples.

And the good news is that after 6 years Hayabusa 2 returns with the first gas sample of an asteroid. And thus it has achieved a new milestone in space exploration.

Full story of Hayabusa 2

Yesterday, when Hayabusa2 dropped the capsule full of gas from the asteroid, it began a new chapter. For asteroid sample collection Japanese state agency called JAXA had sent Hayabusa in 2010 to collect samples from an asteroid. It successfully completed the mission by bringing in the rock samples.

In this series, the second mission was a more advanced series called Hayabusa2. Hayabusa in Japanese means peregrine falcon.

 Launched in 2014 it reached Ryugu in the mid of 2018. It collected gas samples and stayed there for a year or so. And then it started its journey back in 2019 and reached back to earth on December 5.

The satellite’s design is almost similar to its predecessor. Weighing around 600 kg including fuel this is one of its kind.

It gets it’s electric power through 2 arrays of solar panels. With a total output of 2.5kw the electricity was more than sufficient to carry out exploration and send back the details while it was near the asteroid.

Lithium ion batteries stored the energy for the satellite. With a total capacity 13.2Ah these batteries sustained the entire journey without a glitch.

In place of conventional thrusters it used μ10 for propulsion. The spacecraft had 4 such thrusters based on solar-electric ions.

These thrusters use microwaves to generate plasma through xenon. And then the voltage helps to accelerate the ion that is thrown through the back for the required push.

To be precise Hayabusa is not bigger than a small car. In fact it might be even smaller to the smallest of the cars. Anyhow, the work it accomplishes is extraordinary.

Basically it stays 20KM around an asteroid and makes a map of the entire surface. It then finds the right place to land. And once landed it collects the samples and returns back.

And now when, Hayabusa 2 returns with the first gas sample of an asteroid, the Japanese scientists were revealed. They now possess an unmatched priceless asset.

How did the samples enter the earth?

It was not the entire satellite that came back to earth. Rather it dropped a capsule with the gas. This capsule entered the earth’s atmosphere and after struggling through the friction from air it safely landed in the deserts of Australia.

Scientist were escalated to get the samples.

Hayabusa will also cover two more asteroids before it ends is mission after a few years.

When Hayabusa 2 returns with the first gas sample of those asteroid that it will cover next, the history will be repeated. It will open more doors to the quest of human existence on this earth.

Purpose of this mission

This mission will open new secrets that were hidden until now. These secrets might lead us further towards the knowledge of the existence of earth and life. The beginning.

For billions of years earth had been bombarded with millions of meteors and asteroids.

Many scientists believe that life on earth came from some remote asteroid that hit the earth. This might have happened billions of years ago. But, we still need to find the traces of that event.
