Overview 1 first 360 degrees live stream from space

SpaceVR, a new startup, has signed a deal for the world's first satellite equipped with a camera capable of shooting video at 360 degrees to reach space.

The vehicle, called Overview 1 will be placed aboard a SpaceX Falcon 9 rocket next summer, says Go4It.

The ship will carry the satellite into the International Space Station, where it will be placed later on a low Earth orbit by NanoRacks LLC, the company that operates commercially module aboard the station.

Content to be recorded by the camera on Overview 1 can be seen through a VR headset.

SpaceVR wants to do, ultimately, a permanent live broadcast from space via satellite.

Customers will have to pay subscription to access the stream.

Unusual phenomenon on the surface of one of Jupiter's moons. It's happening every 42 hours

The process was known by researchers, but could be noticed only recently.

Atmosphere Io, one of the largest moons's Jupiter, freezes and thaws every time the subject comes from cosmic giant planet. The phenomenon of extreme cooling takes about 2 hours, out of the 42 that Io makes a complete orbit around Jupiter. It is the first time scientists were able to observe this process.

Io's atmosphere is composed mostly of sulfur dioxide formed during volcanic eruptions on Jupiter. Until now it was assumed that Io's atmosphere turns into ice during the 2 hours that satellite is in the shadow of the planet, but no one has managed to prove this.

Recently, a team of astronomers led by Constantine C.C. Tsang used ground-based telescopes to observe the natural satellite of Jupter. With this device could emit infrared specialists, which once reached Io's atmosphere, they were absorbed by sulfur dioxide. In this way, the researchers were able to measure the surface temperature of cosmic object.

It has been found that, when Io is behind Jupiter, the surface temperature of the satellite decreases from -146 degrees to -168, making the atmosphere of Io to freeze the extent of about 80%. After two hours the object is in this state, the sulfur dioxide contained in atmosefera evaporated and converted back into gas.

Scientists say that recent results will help us to better understand the system in which the center is Jupiter. In this regard, experts have already estimated that over half of sulfur dioxide from volcanoes on Io propelled arrive, finally, to circulate around the gas giant.
