A japanese spacecraft Hayabusa 2 has successfully touched down on a speeding asteroid 300 million kilometers from the earth as it. Hayabusa collect samples and bring them back for scientist to study at 11:30pm GMT. This Hayabusa2 spacecraft operated by the japanese space agency,JAXA.
The Hayabusa 2 probe touched down on the asteroid ryugu at around 11:30pm GMT on thursday . Hayabusa2 launched in 3 December 2014,4:22am GMT and return the samples to Earth in December 2020 in Woomera,Australia.This total cost of this project(Hayabusa2) is 1,640 crores JPY(2010) (US$146 million).
Hayabusa has launched mass 510 kg (1,120 lb) but Hyabusa 2 has more wheights 609 kg (1,343 lb) as compare to hayabusa 1.The design of Hayabusa 2 is based on the first hayabusa spacecraft, with some matured improvements. On 21 September 2018, the Hayabusa2 spacecraft ejected the first two rovers, Rover-1A and Rover-1B, from about 55 meters altitude that fell independently to the surface of the asteroid.
The Hayabusa 2 payload incorporates multiple scientific instruments-
- Remote sensing: Optical Navigation Camera (ONC-T, ONC-W1, ONC-W2), Near-Infrared Camera (NIR3), Thermal-Infrared Camera (TIR), Light Detection And Ranging (LIDAR)
- Sampling: Sampling device (SMP), Small Carry-on Impactor (SCI), Deployable Camera (DCAM3)
- Four rovers: Mobile Asteroid Surface Scout (MASCOT), Rover-1A, Rover-1B, Rover-2.
The spacecraft will collect three samples and store them in separate sealed containers inside the sample-return capsule (SRC),which has a thermal insulation , 40 cm external diameter, 20 cm in height, and a mass of ~16 kg.
JAXA spokeswoman Chisto lkuta said that control centre had “received data that shows that the probe is working normally and is healthy.” Scientists are continuing to gather and analyse data from the probe, she said.
The probe was due to fire a bullet at the Ryugu asteroid , to stir up surface matter, which it will then collect for analysis back on earth. The asteroid is thought to contain relatively large amounts of organic matter and water from some 4.6 billion years ago when the solar system was born.
