Before the descent began, Haiabusa2 was hanging in its "home position," about 12.4 miles (20 km) above the surface of the asteroid. The spacecraft is approaching closer in the next few hours, sending images from its navigation camera about twice per hour. These images take about 1

During the first few hours of the launch, the spacecraft dropped at about 35 inches / second (90 centimeters per second), which was about twice as fast as initially planned by JAXA to compensate for the start of the downgrade about 5 hours later than planned. By February 21 at about 9:15 EST (1415 GMT), Hayabusa is just 1.8 miles (3km) above the surface.
Hayabusa2 is scheduled to touch around 6:06. EST (2306 GMT). On the surface will shoot what is essentially a bullet into the gravel surface of Ryugu and sucks the resulting debris to bring them back to Earth. to return to its "starting position". The ship still has a lot of work in Ryugu, including releasing another small rover onto the surface of the asteroid before returning to the end of this year.
