NASA is setting up a rocket rocket to look closer to the way the Earth's atmosphere slowly spreads into space.
Understanding atmospheric escape in the Earth has applications throughout the Universe – predicting how remote planets could be inhabitable, to settle together as Mars became the desert, exposed landscape, it is today, the US space agency said.
The VISIONS-2 mission, short for Visualizing Ion Outflow by Neutral Atom-Sensing 2, is scheduled to launch no later than December 4.
A sounding rocket makes short, targeted flights into space before returning to Earth just a few minutes later.
Sounding rockets are unique among science spaceships for their superiority.
They can be carded to distant places where they are directed and shot into short events – such as the sudden formation of the aurora borealis – at a moment.
The Aurora boreal is very interesting for the VISIONS 2 team, but not only for its other world.
The golden game is fundamental drivers in the process of atmospheric exhaust, in which planets, including Earth, gradually filters their atmosphere into space.
"The Earth loses weight," said Thomas Moore, a space physicist of NASA.
"Sufficient observations knew that every day came into a space of one hundred and fifty-fifty tons of atmosphere," said Moore.
Moore estimates that at that time, Earth will retain its atmosphere for millions of years or so.
Scientists have long thought that oxygen, weighing 16 times the mass of hydrogen, was too heavy to escape the Earth's gravity.
However, a near-Earth space is growing much more Earth-drawn oxygen than anyone expected.
The aurora is formed when energy electrons, accelerated in the electric and magnetic fields in a near Earth space, crash and stir at atmospheric gases that emit bright, green, and yellow tones when they slow down to lower energy.
These unusual electrons also create a breakdown in the process, including the conduct of electric currents that heat the upper atmosphere in split patches.
In some cases, this heating is enough to give hope of oxygen enough energy to escape.
VISIONS-1, the predecessor of the current mission, launched by the Poker Flat Research Range in Alaska in 2013, where they studied an oxygen current of aurora, which forms on Earth's night side, the part of the planet that is temporarily noted by the Sun.
For the VISIONS-2 mission, the team will travel to Svalbard – an isolated archipelago from the northern coast of Norway, where there is an audio clock.
VISIONS-2 is the first of nine rocket rockets launching during the next 14 months as part of the Great Challenge Initiative, international cooperation to explore the unusual portal between Earth and space.
