2007 in spaceflight Moon. Japan's Kaguya orbiter, along with the smaller Okina and Ouna relay spacecraft, was launched on 14 September. The spacecraft entered Selenocentric orbit on 3 October. China launched its first Lunar probe, Chang'e 1, on 24 October, with the spacecraft entering Selenocentric orbit on 5 November. In 2009, two satellites launched into highly elliptical Earth orbits in 2007 as part of the THEMIS mission were also sent to the Moon. They are expected to arrive in October 2010. In August, the NASA Phoenix spacecraft was launched towards Mars, followed by the Dawn mission to the Asteroid belt in September. Cassini
Antoniadi (lunar crater) unusually flat and smooth, with the central peak being the only notable feature. The floor outside the inner ring is much rougher in texture. The most notable crater on the interior floor lies across the eastern edge of the southern inner ring range. The bottom of Antoniadi crater is measured—by using the laser altimeter (LALT) instrument on board the Japanese Selenological and Engineering Explorer (SELENE) satellite—to be the lowest point on the moon (provisionally named Point Trieste after the Bathysphere Trieste that was the first vehicle to descend to the world's deepest point) and rests 9 kilometers (more than 5.5
