Hayabusa 2: Japan probe to send lander to asteroid Image copyright DLR Image caption Artwork: Hayabusa-2 should release Mascot in the early hours of Wednesday Japan's space agency (Jaxa) is about to send a 10kg lander to the surface of an asteroid.
The Hayabusa-2 spacecraft will release the German-French Mascot lander onto the asteroid 162173 Ryugu on Wednesday.
Mascot will then analyse the asteroid's surface properties, including its mineral composition and magnetic field.
Hayabusa-2 reached the asteroid Ryugu in June this year after a three-and-a-half-year journey.
On 21 September, Jaxa celebrated a first, as its "mothership" deployed two robot explorers to the surface of Ryugu.
Now, it's the turn of the Mobile Asteroid Surface Scout (Mascot), which has been built by the German Aerospace Center (DLR) and the French Space Agency (Cnes).

Why Sulawesi's tsunami is puzzling scientists Image copyright AFP Image caption The quake was large - but not of the type normally associated with a big tsunami event Friday's catastrophic tsunami event on Sulawesi Island is a puzzle.
As the emergency response gathers pace, scientists are scratching their heads to understand why it generated such big waves.
The magnitude 7.5 quake was certainly large - one of the biggest recorded anywhere on the globe this year.
But it was what geophysicists call a strike-slip event, where the ground breaks horizontally. In this instance, the rock to the east of the fault running up through the island moved northwards relative to the rock to the west.
Strike-slip quakes can cause tsunami events but the 6m-tall waves that crashed ashore at Palu city surprised everyone.
Remember that to make the series of waves you need a big displacement of the sea-floor - a vertical movement that disturbs the entire water column, which then moves away in all..

On 23 August, Sandhini Gopakumar, a 34-year-old housewife, returned to her home in the flood-ravaged city of Cochin with her husband and two children. They had been forced to spend five days in three different emergency relief camps.
"On my way back home, I saw the bloated bodies of cattle floating in stagnant water," recalls Sandhini. "How were we going to clean this up? I thought. How many days would we need?"
Why the Kerala floods proved so deadlyThe floods were the worst to hit Kerala in a century. Hundreds were killed and more than a million displaced. Like Sandhini and her family, many took shelter in relief camps spread across the state.
