Thanks for the informative link, DW!
Never mind the double posts. You don´t need to hang on. The trick is to save your content, and then look at "What is new" to see if your content hasn´t been posted already. If it is there, you can leave the page.

More information on Hayabusa2. The Japanese are planning to sample several asteroids in the asteroid belt to learn more about asteroids in general. Quite smart to do this!
I guess the Japanese are good scientist. And they also that they have provided the money for the research.

Here is a very recent comparison study on Ryugu:

The Japanese plans are complex, they are planning to land a series of landing craft on the asteroid. That are still approaching the asteroid, doing it carefully.
Hayabusa 2 has already been providing the first-ever close-up views of this asteroid, which is classified as a near-Earth object. The images show a roughly diamond-shaped body – also being compared to a spinning top – with boulders and craters.
Hayabusa 2 aims to study Ryugu in detail, deposit a European and a series of Japanese landers on the surface and return a sample of ancient asteroid rock back to Earth in 2020. The tweet below simulates your eavesdropping on the craft as its tells its MASCOT lander – designed to hop from place to place on Ryugu’s surface – to wake up!

The Cassini orbiter revealed many fascinating things about the Saturn system before its mission ended in September of 2017. In addition to revealing much about Saturn’s rings and the surface and atmosphere of Titan (Saturn’s largest moon), it was also responsible for the discovery of water plumes coming from Enceladus‘ southern polar region. The discovery of these plumes triggered a widespread debate about the possible existence of life in the moon’s interior.
This was based in part on evidence that the plumes extended all the way to the moon’s core/mantle boundary and contained elements essential to life. Thanks to a new study led by researchers from of the University of Heidelberg, Germany, it has now been confirmed that the plumes contain complex organic molecules. This is the first time that complex organics have been detected on a body other than Earth, and bolsters the case for the moon supporting

Time for refreshments!
SpaceX Dragon Delivers 'World's Strongest Coffee,' Blueberries & More to Space Station
"A SpaceX Dragon cargo ship arrived at the International Space Station early Monday (July 2) carrying nearly 3 tons of supplies for astronauts, including super-caffeinated coffee, Texas blueberries and an extra special treat: ice cream bars.
The Dragon, which astronauts captured using a robotic arm at about 6:54 a.m. EDT (1054 GMT), is carrying a batch of Death Wish Coffee — billed as the "world's strongest coffee" — for astronauts to enjoy in orbit.
"We like to keep our astronauts super-caffeinated because they work harder," Kirk Shireman, NASA's space station program manager, joked just after SpaceX launched the Dragon mission Friday (June 29). Jokes aside, Shireman said he's tried the coffee. It was different and new, and that's really the point behind all the goodies on this flight. [In Photos: SpaceX's Dazzling Dragon Launch to Space Station]
"Food's a huge psychological benefit," Shireman said. "When you're living in a closed environment, you're basically eating the same menu every 8 or 9 days, and then you repeat. So, having something different is a real treat."

Important research:
Why bacteria survive in space
Hardy organisms threaten interplanetary contamination

Summary:
Earth germs could be contaminating other planets. Despite extreme decontamination efforts, bacteria from Earth still manages to find its way into outer space aboard spacecraft. Biologist are working to better understand how and why some spores elude decontamination.

"DAWN MISSION TO CERES EXTENDED
NASA
NASA has authorized a second extension of the Dawn mission at Ceres, the
largest object in the asteroid belt between Mars and Jupiter. During
this extension, the spacecraft, which has been orbiting Ceres since 2015
March, will descend to lower altitudes than ever before. The spacecraft
will continue at Ceres for the remainder of its investigation and will
remain in a stable orbit indefinitely after its hydrazine fuel runs out.
The Dawn flight team is studying ways to manoeuvre Dawn into a new
elliptical orbit, which may take the spacecraft to less than 200 km from
the surface of Ceres at closest approach. Previously, Dawn's lowest
altitude was 385 km. A priority of the second Ceres mission extension
is collecting data with Dawn's gamma-ray and neutron spectrometer,
which measures the number and energy of gamma rays and neutrons. That
information is important for understanding the composition of Ceres'
uppermost layer and how much ice it contains. The spacecraft will also
take visible-light images of Ceres' surface with its camera, as well as
measurements of Ceres' mineralogy with its visible and infrared mapping
spectrometer.
The extended mission additionally allows Dawn to be in orbit while Ceres
goes through perihelion, its closest approach to the Sun, which will
occur in 2018 April. At closer proximity to the Sun, more ice on Ceres'
surface may turn to water vapour, which may in turn contribute to the
weak transient atmosphere detected by ESA's Herschel space observatory
before Dawn's arrival. Building on Dawn's findings, the team has
hypothesized that water vapour may be produced in part from energetic
particles from the Sun interacting with ice at shallow depths in Ceres'
surface. Scientists will combine data from ground-based observatories
with Dawn's observations to study these phenomena further as Ceres
approaches perihelion."
