Carnival of Space 365 is up at Aartscope. This is 7 years of the Carnival of Space.
Universe Today – NASA announced the winners of a high stakes science instrument competition to fly aboard the Mars 2020 rover at a briefing held today, Thursday, July 31, at the agency’s headquarters in Washington, D.C.
Universe Today – Scientists analyzing the reams of data from NASA’s Cassini orbiter at Saturn have discovered 101 geysers erupting from the intriguing icy moon Enceladus and that the spewing material of liquid water likely originates from an underground sea located beneath the tiny moons ice shell, according to newly published research.
Nextbigfuture – Success and validation that aligns with what is believed about EmDrive means powerful mainly static thrust. It would be an alternative way to achieve effects that would mimic antigravity. It would enable super efficient planes, better flying cars, and cloud city like applications in a full expression of a mature EmDrive. In the nearer term it would be better satellite propulsion. A US scientist, Guido Fetta, has built his own propellant-less microwave thruster, and managed to persuade Nasa to test it out. The test results were presented on July 30 at the 50th Joint Propulsion Conference in Cleveland, Ohio. Astonishingly enough, they are positive.
The Nasa team based at the Johnson Space Centre gave its paper the title “”Anomalous Thrust Production from an RF [radio frequency] Test Device Measured on a Low-Thrust Torsion Pendulum””. The five researchers spent six days setting up test equipment followed by two days of experiments with various configurations. These tests included using a “”null drive”” similar to the live version but modified so it would not work, and using a device which would produce the same load on the apparatus to establish whether the effect might be produced by some effect unrelated to the actual drive. They also turned the drive around the other way to check whether that had any effect.
Last year a Chinese team built its own EmDrive and confirmed that it produced 720 mN (about 72 grams) of thrust, enough for a practical satellite thruster. Such a thruster could be powered by solar electricity, eliminating the need for the supply of propellant that occupies up to half the launch mass of many satellites. The Chinese work attracted little attention; it seems that nobody in the West believed in it.
Nextbigfuture – Controversial Blacklight Power claims that they can release 700 joules in half a millisecond in ten millionth of liter. Power density 100 billion watts per liter in the form of light. This can be done thousands of times per second. They claim to get 200 times the energy of hydrogen from hydrinos. Hydrinos are a new form of hydrogen with fractional electron orbits. They get hydrinos via various catalyst methods. If this were to be achieved energy production and space travel and space access would be transformed.
