Hayabusa2 probe touches down on asteroid

The successful landing follows on from the deployment of two small rovers back in September of last year.
There was a great deal to celebrate at the Japan Aerospace Exploration Agency (JAXA) command center today as the spacecraft, which launched back in 2014, landed on the surface of Ryugu.

Part of the agency's ongoing MINERVA-II1 program, the probe has been equipped with a special instrument designed to fire a small projectile in to the surface and expel material from underneath.
Its ultimate goal is to collect a sample and return it to the Earth for further study.

"We made the ideal touchdown in the best conditions," said project manager Yuichi Tsuda.

If all goes well, the sample will be returned to Earth next year.

The discolouration could have been caused by grit being blown upwards by the spacecraft's thrusters, or by the bullet it fired into the ground."

"A movie captured by Japan's Hayabusa-2 spacecraft shows the moment it touched down on an asteroid. The probe was attempting to grab a sample of rock from the 1km-wide body known as Ryugu, on 21 February (GMT). The footage shows dusty fragments lifting up as the spacecraft fires a "bullet" at 300m/s into the surface." Video at the BBC: https://www.bbc.co.uk/news/science-environment-47459248

Its been revealed at the Lunar and Planetary Science Conference that the Asteroid Ryugu, is very rocky, and relatively young as asteroids go, less than 100 million years old. It's also reported to be very dry, and is one of the darkest objects in the solar system. It's  thought to be of the 'rubble pile' class of asteroids, made of many loosely consolidated pieces, with a good deal of open space between them.         The Hayabusa 2 probe will eventually fire a large projectile into the asteroid, leaving a 10 meter-wide, one meter-deep crater. This should turn up some deeper sample materials th... [More]

Hayabusa 2 is set to fire its large, crater-making projectile into asteroid Ryugu tomorrow, at 2:36 GMT. The projectile, made of a slightly curved copper plate will be formed into a cone by its explosive launch. It will be launched from a detachable unit, while Hayabusa 2 retreats around to the back of the asteroid to avoid being struck by any of the flying debris. Once the dust settles, in a couple of weeks, they'll bring it back around to inspect the new crater. They hope to eventually land and collect samples from the crater and/or its surroundings.

The large  Hayabusa 2 projectile was successful in striking the surface of asteroid Ryugi. A deployable camera was just able to catch sight of the impact. A slight trace of debris could be seen rising from the surface of the asteroid. This debris appeared to rise at an angle, suggesting that the impactor may have struck an inclined surface, rather than flat terrain. There was only limited accuracy in selecting where the projectile would land. Given the possible slope, and the very low gravity on the asteroid, it's conceivable that the impact inadvertently caused a landslide. In a few weeks Hay... [More]

 Judging by the video of alternating 'before' and 'after' images, the explosion appears to have pushed several rocks outward from the center of the explosion area, without blasting them entirely out of the newly formed crater.  It appears that the bulk of the excavated material, now missing from view, was relatively fine-grained.
