At 10.05pm GMT, Habauysa’s altitude was recorded at 656.2ft (200m) above Ryugu.
Before the mission was given the green light to go earlier today, Hayabusa-2 hovered over the space rock at a distance of about 12.5 miles (20km).
The spacecraft then spent the next few hours, gradually approaching and accelerating towards Ryugu.
Unfortunately, once the probe lands on Ryugu, Hayabusa’s position will make it impossible to beam images back to JAXA on Earth.
