Virgin Galactic’s founder, Richard Branson, had initially suggested that he hoped to see a maiden flight by the end of 2009, but this date has been delayed on a number of occasions, most seriously by the October 2014 in-flight loss of SpaceShipTwo VSS Enterprise. Branson stated that Virgin Galactic was “in the best position in the world” to provide rocket-powered, point-to-point 3000 mph air travel on Earth. While Branson suggested, in October 2017, that he could travel to space aboard a SpaceShipTwo within six months, it was not until 13 December 2018 that VSS Unity achieved the project’s first suborbital space flight, reaching an altitude of 82. 7 kilometres (51. 4 mi), officially entering outer space by US standards. The project carried a third person as a passenger in February 2019, when a member of the team sat and floated within the cabin during a flight that reached 89. 9 kilometres (55. 9 mi).
An Icy Nest Of Space Eggs. Methone is actually only one member of an icy nest of Space eggs, which also includes the very strange and smooth moons of Saturn, Pallene and Aegaeon. Aegaeon is a very, very small moonlet that also twirls around between Mimas and Enceladus. Like Methone, Aegaeon displays a mysteriously unblemished surface.
There was a time when Earth had no Moon. About 4.5 billion years ago, when our ancient Solar System was still forming, the dark night sky above our primordial planet was moonless. At this time, the Earth was about 60 percent formed, although it did have a differentiated crust, mantle, and core. This was a very chaotic and violent era in our Solar System's past, with planets first forming out of blobs of primordial dust, gas, and rock. During this era, frequently likened to a "cosmic shooting gallery", collisions between the still-forming planets were commonplace. Orbits were not as orderly as they are now.
Saturn is a lovely planet, with its magnificent system of gossamer rings, shining moons of ice, and myriads of glimmering, frozen, dancing moonlets that twirl and somersault both inside and outside of the enchanting system of rings.
