 NASA recently tested a new rocket-powered turbine for methane, which could become the key technology for future exploration of the outer solar system.
The main turbine, built and tested by the team of NASA contractors, Alliant Techsystems and XCOR Aerospace, is still under development and, therefore, is not ready yet to be carried into space. But if you can show that this technology is viable, the turbines like this one powered by natural gas could eventually be key to deep space exploration.

 Solar physicist David Hathaway has been watching the Sun every day since 1998, and every day for six years found sunspots. Sunspots are “islands” sized planets, which appear on the surface of the sun are dark, cool, powerfully magnetized, and fleeting: a typical sunspot lasts only a few days or weeks before disappearing. As soon as one disappears, another emerges to take its place.
Even during the period of solar minimum activity, you can see one or two sunspots. But when Hathaway looked on 28 January 2004, there were none. The sun was utterly blank.
And the same happened again last week, twice, 11 and 12 October. There were no sunspots.

The end of the accumulation of nuclear weapons during the Cold War means that the U.S. space agency has enough plutonium for future probes on distant missions, except for a few missions already planned, according to a new study by the National Academy of Sciences United States.
Deep space probes past Jupiter can not use solar energy because they are far from the sun. Thus, its energy supply depends on a particular type of plutonium, plutonium-238. This feeds the spacecraft with the energy released during its natural decay. But the plutonium-238 is not found in nature, is a byproduct of engineering arms.

The largest planetary ring found so far in the solar system is circling Saturn, about 13 million miles from Earth, as revealed in the infrared images from Spitzer Space Telescope from NASA. This is a huge ring of dust particles, but so dim that it is not evident at first glance.
A team of astronomers from the Universities of Virginia and Maryland in the USA has encountered a huge ring around Saturn thanks to images provided by the infrared Spitzer Space Telescope for NASA. “It’s a super ring and if visible (from Earth) appears to be twice the size of the moon,” says Anne Verbiscer, University of Virginia. The researcher has reported the finding at the congress of the Division for Planetary Sciences of the American Astronomical Association, which this week celebrated in Puerto Rico.

 The lunar south pole region Crater
U.S. Space Network reported that since the first human landing on the moon will be part of the lunar samples brought back to Earth, scientists believe the moon’s surface is a completely dry world. However, based on three different spacecraft, the latest observational results conclusive evidence – on the lunar surface over the water.
