Virgin Galactic Spacecraft Dream Chaser

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).



Beneath The Icy Crust Of Enceladus. The research paper written by scientists with the Cassini mission, published in the journal Science, suggests the presence of hydrogen gas. Hydrogen gas, that could potentially provide a chemical energy source for life, is pouring into the subsurface ocean of Enceladus from hydrothermal activity on the seafloor of this bewitching, distant moon-world. It is not a very expensive stone and is made into necklaces or bigger pieces for jewelry purposes. I especially like the deep, dark blue version with golden pyrite sprinkles creating very unique patterns mined only in Afghanistan. The lighter blue, grayish variety is found in Chile. The findings of the two missions are presented in papers published on April 13, 2017, by planetary scientists with NASA's Cassini mission to Saturn and the venerable Hubble Space Telescope (HST). In one of the papers, Cassini scientists announced their discovery that a form of chemical energy life can feed on appears to exist on Enceladus. In the second paper, HST researchers report additional evidence of plumes erupting from Jupiter's moon, Europa, whose fascinating frozen crust of ice resembles a cracked eggshell. It has long been recognized by planetary scientists that beneath Europa's bizarre cracked shell of ice, there is a sloshing global ocean of liquid water.
