EarthÂ’s atmospheric methane can be detected from space, using special instruments. If life forms exists on Mars, it is plausible that some of them might use methanogenesis for energy.

Both the Spirit and the Opportunity roving vehicles carry a device called the Mössbauer Spectrometer, which is able to tell the difference between two forms of iron in chemical compounds in the Martian soil and rocks. If the Martian surface contains H2O2 or other oxidizing agents, then a lot of the iron should be in ferric, or oxidized form (Fe+3). However, if the Maritan surface is more reduced, then a lot of the iron should be in the ferrous or reduced form (Fe+2).

Named in honor of Charles DarwinÂ’s sea ship, the Beagle 1, the European Space Agency's Beagle 2 carried an instrument designed to look for organic molecules and to do so even more capably than the Viking probes.

Did tiny life forms similarly thrive on ancient Mars? And, if so, might their decendants survive somewhere on the dried-out Mars of today? Back in 1971, most of the scientists of the Mariner 9 team were not very hopeful about this possibility.

Unlike the last three Mariner probes that had flown by the planet Mars quickly, with limited time for observations, Mariner 9 entered into orbit where, after waiting out a dust storm, the craft spent a year sending thousands of photographs back to Earth, covering almost 100% of the Martian surface.

When Mariner 4 arrived, it took 22 photographs; the first close up pictures of the Martian surface. Mariner 6 and Mariner 7 arrived at Mars four days apart in the middle of 1969. These missions were important in the history of the search for life on Mars

During Project Viking, scientists tested for the possibility that photosynthetic microorganisms might inhabit Mars. They employed the Pyrolytic Release Experiment (PR) developed by Norman Horiwitz. In a way, the PR was the opposite of the LR.

Designed by Gilbert Levin, one biology experiment carried by the two Viking landing probes in 1976 was known as the Labeled Release (LR) Experiment, because it employed a solution of test nutrients, labeled with carbon-14 (14C). Levin maintains that the LR actually did detect life forms on Mars, and over the years he has built some degree of support, a few scientists agreeing with him that the experiment detected life, but many more deciding that it may have detected life.

To many, the discoveries of the first orbiting Mars probes were disappointing, particularly outside of the science community, where popular culture of the time still included elements remaining from the days when astronomer Percival Lowell had announced to the world that he believed Mars to be inhabited –by intelligent beings.

There are certain things that should be considered by the Astronauts and Cosmonauts upon going into the outer space. These are the risk that they might get encountered into the outer space upon their explorations. These risks could endanger them as far as their safety and health is concern.

For centuries, its primary instrument has been the telescope, but space scientists, planetary scientists in particular, use microscopes too. Beginning in 1969, scientists began using microscopes to examine lunar rocks and dust carried to Earth by Apollo astronauts. Similarly, they employ microscopy in the analysis of cometary material and meteorites.

We keep hearing of a new planet or moon that might hold life. Or of projects to monitor radio signals, or even send them a message. Finding life somewhere beyond EarthÂ’s atmosphere would be wonderful. About five hundred planets have now been discovered. Many moons too. Is there life out there? Here is a summary of what has been found.

The Sun is an ordinary star that is the primary source of heat and light for all the planets in our solar system. This heat and light is the cause of the continuous existence of life on Earth. Without these two crucial elements, we would have never existed when the planet was created.
