NASA Announces That Life is Out There

There is something out there - so NASA says. The U.S. space body announced that life producing water exists on Mars and more information on Pluto is about to come out soon. The New Horizons spacecraft is working perfectly and data collection is continuing.
New Horizons spacecraft photographing Pluto
High resolution photographs have been taken of Pluto for some time now. They have been analyzed. Findings will interesting. It seems we are not totally alone. Life seems to be everywhere in the cosmos.

Pluto even has its own weather. The "environment" changes like here on Earth. Apparently the planet is geologically active. NASA has only downloaded 10 per cent of the data so far. Some fascinating insights will be made known on Thursday.

Australia Had an Input into the Voyager Achievement

It is said there is nothing like blowing your own trumpet. Well, in some cases it can be very pleasing. The fact that the Voyager 1 probe has pass into space beyond the solar system is good news, The US must take most of the praise, but a small country in terms of population played a major part.

Australian scientists are base at Canberra's Deep Space Communication Complex (CDSCC). The controlling body is the Commonwealth Scientific and Industrial Research Organisation (CSIRO). This company is a big mover in world science. Many new ideas, concepts and discoveries have their origin at CSIRO.

The world's most advanced antennas are situated at the CSIRO base and they have been following Voyager since its launch in 1977. A round trip for a signal forward and back between the Earth and satellite is 34 hours.

There are two probes, Voyager 1 and 2. Only one is in deep space. Due to improvements in technology the antennas have been constantly upgraded as the probe journeyed further outward. Current technology allows contact to be maintained until 2020. It is hoped new improvements will extend this period.

Japan Steps into Space

Let us wish the Japanese well in their bid to explore space. The US has had great success with their missions. It seems odd why Japan would spend money on space exploration when the economy is in such bad shape. Nonetheless, all people in the world benefit from new knowledge,

After success with its first attempt to retrieve samples from the Itokowa space rock, the second spacecraft Hayabusa2 will be launched in 2014 and closely examine asteroid 1999 JU3. The rendezvous will take place in 2018. Valuable samples will be brought back to Earth in 2020.

Japan is doing the work with assistance from other nations. The probe will be tracked by NASA's Deep Space Network. Like the first project the spacecraft will land in Australia. Powered by ion engines the craft will make a small crater in 1999 JU3. In the past this asteroid may have come into contact with water.

A German made lander called MASCOT will move over the rock's surface. Intense examination will hopefully bring to light new understanding about asteroids. The search for life elsewhere in the cosmos is still paramount.

There Is Soil on Mars

NASA scientists are now saying that "soil" on Mars could support vegetable life. Without an atmosphere, though, it seems no life is possible. Scientists are specific enough to say that asparagus and turnips will grow in Mars' soil but strawberries will not. Are they joking? Or are they for real?

The Phoenix Mars Lander found soil that is very much like that in many Earth backyards. Scientists are shocked that they have found soil. It is alkaline - thus, the claim that it is not good for strawberries. Apparently, the soil is rich in trace minerals.

My, how scientists can be wrong. It was thought that Mars "soil" would be salty - with no atmosphere and the sun would bleach it. But they were wrong. At least we know that there is soil and water in the form of ice just beneath the surface. There is evidence that in the past water flowed on the surface because erosion is evident. Rivers, lakes and oceans existed there once. Water reservoirs such as these indicate that the planet did once have an atmosphere.

If life did survive for a time on Mars future exploration will surely find it.

No Satellite Nation Will Claim Mysterious Metal Globe

It isn't ours says the US, Russia and Germany. A mysterious metal ball, two hemispheres welded together, has fallen to earth in Namibia. The "ball" is 35 centimeters wide and cut a groove in the ground on impact 33 centimeters deep and 3.8 meters wide. The hollow sphere is not dangerous - it isn't an explosive devise.

There were two recent orbital crises with satellites crashing to the ground: NASA's Upper Atmosphere Research Satellite and Germany's Roentgen Satellite. The mystery object is not part of any of these. The Phobos-Grunt Mars Probe made in Russia will also soon come down.

There is the possibility that it could be from a satellite much older, something that has been orbiting for a long time. If this is the case, ownership of the space debris may never be known because no country wants it known that satellite parts can fall at random from the sky.

Blue Straggler Stars Found in the Milky Way Bulge

We now know that dark matter exists. NASA's Hubble Space Telescope has also identified blue straggler stars in the Milky Way. These stars don't show their age. Their color hides their true age. This is the first time they have been found in the core of the Milky Way.

Not much is known about blue stragglers. Accepted theory is that they develop from binary pairs. The larger of the pair strips material from the smaller one. Hydrogen is activated which causes the larger star to undergo nuclear fission thus making the star blue.

Blue stragglers are rare in the Milky Way because the central bulge of the system stopped making new stars billions of years ago. Aging stars and cool red dwarfs exist in the Milky Way now. Giant blue stars were thought to have exploded into supernovae in the distant past. The presence of blue stragglers throws a spanner into the works of current models of star formation.
