Venus Planet Nasa

In September 2015, a new study provided an important missing piece to the intriguing puzzle of how our Moon came to be the lovely object that we see today. Unfortunately, the various economic troubles which are plaguing Europe has caused ESA to spend less money than before, so many space programs in Europe has halted. However, both in China as well as in India, there are several ambitious programs present, which may cause any one of these nations to send another man to the moon in the next decade. Naturally, only time will tell; but nothing will change the fact that mankind's future is in the stars. Since its discovery centuries ago, Ganymede has been the target of a great deal of well-deserved attention from the planetary science community. Earth-bound telescopes have gazed at Ganymede's puzzling, icy surface and, in later decades, flyby space missions and spacecraft, circling around Jupiter, have scrutinized Ganymede--trying to solve its numerous mysteries. These observations ultimately unveiled a complicated, icy moon-world, whose bizarre surface showed a strange and puzzling contrast between its two main types of terrain: the dark, extremely ancient and heavily cratered surface terrain, and the much younger--but still ancient--lighter terrain showing a vast array of mysterious grooves and ridges.
