Spacecraft Hayabusa2 Returns Photos of Asteroid Prior To Contact (syfy.com)
New submitter FranklinWebber writes: Spacecraft Hayabusa2 is approaching its target, asteroid Ryugu, after a three-and-a-half year trip. The Japan Aerospace Exporation Agency (JAXA) has released photos of the asteroid taken from a distance of several hundred kilometers and showing a diamond-shaped object.
Like its predecessor spacecraft a decade ago, Hayabusa2 is designed to collect samples from an asteroid and return them to earth. JAXA explains: "A C-type asteroid, which is a target of Hayabusa2, is a more primordial body than Itokawa [the target of Hayabusa and an S-type], and is considered to contain more organic or hydrated minerals.... we expect to clarify the origin of life by analyzing [samples from Ryugu]."
The Bad Astronomy blog has more discussion of the mission: "The spacecraft will deploy an impactor that will slam a 2.5 kilo piece of copper into the surface at 2 km/sec. This will dig down into the asteroid, revealing material underneath, which can then be analyzed to understand Ryugu's interior."

Hayabusa2's diameter is roughly 800m and these photos were taken around the 300km mark. That's like taking a photo of a human being from 7km away, but in space...after the mechanical stress of a rocket launch, 3 years of high temperature extremes and radiation, in ridiculously low light levels and on hardware that has to be as close to 100% reliable as you can make it. Hats off to the team, that's pretty damn impressive in my book.
>Hayabusa is a type of falcon
That's funny because of how many other rockets are named falcon. Just from spacex, falcon 9, falcon heavy, bfr/big falcon rocket...
