The long-term value of the Outer Planet
Atmospheres Legacy program is really exciting," said co-author Michael H.
Sharing space science knowledge is part of what NASA's job is,'' said Richard Shope, education and public outreach coordinator for JPL's Outer Planets
The moon's ample supply of helium-3, long touted by space buffs as a potential fuel for advanced fusion reactors, is duly noted, as are the even larger supplies of the substance in the atmospheres of all of the giant outer planets
The sun's influence extends far beyond the orbits of the outer planets
and the vast reservoir of periodic comets known as the Kuiper Belt because the solar wind fills the heliosphere and exerts an outward pressure on the interstellar medium.
The selected proposals address a range of visionary concepts, including metallic lithium combustion for long-term robotics operations, submarines that explore the oceans of icy moons of the outer planets
, and a swarm of tiny satellites that map gravity fields and characterize the properties of small moons and asteroids.
IN THE SHADOWY, frigid domain of the outer planets
, there is a gigantic blue-green world that is orbited by a host of small sparkling moons of ice.
The microcryocooler operates like a refrigerator, drawing heat out of sensor systems and delivering highly efficient cooling to small science satellites orbiting the Earth and on missions to the outer planets
Voyager 1 launched on September 5, 1977, and its main job - along with its sister probe Voyager 2 - was to study the outer planets
on a complicated looping path known as The Grand Tour.
Voyager 1 first detected the pressure of interstellar space on the heliosphere, the bubble of charged particles surrounding the Sun that reaches far beyond the outer planets
, in 2004.
It's a week when the outer planets
are harmonising to allow wisdom, healing and compassion to flow.
In the 1970s and 1980s the outer planets
were aligned in a way that occurs only once every 175 years, and NASA seized the opportunity.
1 billion years ago, triggered by a cataclysmic rearrangement of the outer planets
