The Hayabusa 2 spacecraft is landing. For the second time in history, asteroid samples will come to Earth


On December 3, 2014, Hayabusa 2 flew into space. After a series of tests, the Japanese headed toward the asteroid (162173) Ryugu. She arrived in June 2018. Japan’s Aero Space Exploration Agency initially inspected the object using devices placed on the probe.

The probe is scheduled to enter Earth’s atmosphere just before dawn in Australia. Before that, holding 200 thousand kilometers of our planet, from the main ship Hayabusa 2 small separate capsules, which contains dust from the Ryugu asteroid. This is what the Japanese are worried about.

A small capsule will land somewhere in Australia’s wastelands, about 450 kilometers north of Adelaide. The JAXA team is already waiting for Hayabusa 2. to return. An antenna is positioned in the desert to help detect the flight of the object. JAXA will broadcast live the probe’s return, which will begin on December 5 at 6 pm EDT.

However, searching for the capsule will be challenging because it is only 40 centimeters wide. This will be the second time in the history of man that asteroid samples collected by a space probe will come to Earth. Previously, the probe’s predecessor, the Hayabusa, had done this.

The Hayabusa has 2 gun-like devices. On December 28, 2018, a grassroots gun test was conducted. Scientists have collected a bucket of debris (literally) similar to Ryugu’s surface structure. It was prepared with the help of Professor Hideaki Miyamoto of the University of Tokyo. Artificial debris, specifically chondrite charcoal, simulated the properties of the asteroid – strength, density and composition.

They then fired a missile and watched the situation unfold. Scientists collected impact data and, using a computer, figured out how best to approach Ryugu to collect the samples most efficiently. They also had to remember to ensure the probe’s safety. It is still a fragile piece of equipment.

A projector containing 5 grams of tantalum hit a bucket of debris at a speed of 300 m / s. Exact material was fired from a weapon mounted on a Hayabusa-2 probe. These are just 5 grams to help bring 10 to 100 milligrams of samples back to Earth.
