Hayabusa2 is an asteroid sample-return mission operated by the Japanese space agency, JAXA. It is a successor to the Hayabusa mission which returned asteroid samples for the first time in June 2010. It arrived at asteroid 162173 Ryugu on 27 June 2018, where it surveyed the asteroid for a year and a half and collected samples. It departed the asteroid in November 2019 to return the samples to Earth in late 2020.
About Hayabusa2 in brief
Hayabusa2 is an asteroid sample-return mission operated by the Japanese space agency, JAXA. It is a successor to the Hayabusa mission which returned asteroid samples for the first time in June 2010. The spacecraft features improved ion engines, guidance and navigation technology, antennas, and attitude control systems. It arrived at asteroid 162173 Ryugu on 27 June 2018, where it surveyed the asteroid for a year and a half and collected samples. It departed the asteroid in November 2019 to return the samples to Earth in late 2020. The samples were retrieved the same day for secure transport back to the JAXa labs in Japan. It has 610 kilograms of fuel, and electric power is generated by two sets of solar arrays with efficiency of 2.kW at 1 AU, and 4 W at 4 AU. The power is stored in eleven inline-mounted 13 Ah-mounted lithium-ion batteries. Although this engine generates up to 28m thrusts, this operation is in simultaneous operation of three engines and ejected back out of the back of the spacecraft. The solar panels are accelerated by applying a voltage from the solar panels to convert xenon into plasma which is converted into microwaves to convert to microwaves by the xenon xenon onboard the craft. The first sample collection was scheduled to start in late October 2018, but the rovers encountered a landscape with large and small boulders but no surface soil for sampling. It was decided to postpone the sample collection plans to 2019 and further evaluate various options for the landing.
It successfully delivered the samples back to Earth in 6 December 2020, dropping the contents by parachute in a special container at a location in southern Australia. The mission cost estimated in 2010 was 16. 4 billion yen. Hayabusha2 was launched on 3 December 2014, and remained stationary at a distance of about 20 km to study and map the asteroid. The MASCOT rover deployed successfully on 3 October 2018 and operated for about 16 hours as planned. On 21 September 2018, the Haybusa2 spacecraft ejected the first two rovers, Rover-1A and Rover- 1B, from about a 55 m altitude that dropped independently to the surface of the asteroid, They functioned nominally and transmitted data. The sub-surface sampling took place on 11 July 2019. The spacecraft departed the asteroids on 13 November 2019. It successfully delivers the samples Back to Earth. Back to Mail Online home.

Hayabus2 is based on the same spacecraft, with improvements in design of some of the subsystems, including some in the design of the solar arrays, and some improvements in the power sources. The asteroid is thought to preserve the most pristine, untainted materials in the Solar System, a mixture of minerals, ice, and organic compounds that interact with each other. Studying it is expected to provide additional knowledge on the origin and evolution of the inner planets and, in particular, the origin of water andorganic compounds on Earth.
