The rabbit on the mars

The proof of Auberdirdian life is hardly succeeded in a single photo

The hope of the very gross find is always there. A clearly recognizable microbe on the microscope shot of a marsrovers, a petrified form of life or organic matter as an obvious waste product of biological processes – the goods not only for the scientists involved a reason to cheer. Finally, it’s clear: we are not alone.

An attentive telepolis reader has now even discovered a bit rough. On the on the 2. February 2004 published panoramic recording of the Rovers "Opportunity" I recognized Mirko Kruger "Tuborous object", reminiscent of a Weibek rabbit, and made the Telepolis editors attentively. He wonders why this object has remained uncidized in the press releases of NASA and other media, and see exploratory needs, even if it should be part of the landing device. The object has already been dedicated to its own website.

Lutz Judge from the German Center for Aerospace (DLR), which employs the ROVER’s 50-headed scientific team, says:

I know the picture well, because I was in the JPL control room when these recordings arrived in the days after landing on the ground, and I believe, even the first one that found this object. I then asked some of the Landers engineers who also tapped elements of airbags, for example from the turmoil. But the thing was not pursued, as it had certainly from the spacecraft and apparently did not want to make a malfunction.

The search for life traces is more complicated. The space robots, which now circle the red planet or drive over his surface, will not answer this question with a single picture. You should rather supply mosaic stones to the coarse puzzle, which describes the origin, the development and future of life.

As an important, if not necessary prerequisite for the emergence of life is the presence of water after the present state of knowledge. The Rover of the American space workers NASA has therefore been targeted in regions, show the evidence of the influence of liquid water.

Through extensive instrumentation of the rover, at a tour of a maximum of a few kilometers, the geology and mineralogy of surface materials and stones are characterized in order to examine the more accurate circumstances of the interaction of the gel with water. This will allow jerk luses via various suspected processes associated with water also in other parts of the planet.

Although the European probe Mars Express has already proven the existence of water at the Sudpol and thus thereby refreshed the NASA probe Odyssey data. But this water is in the form of ice, many landscape formations, however, suggest that water has flowed there. River water, however, could not actually exist in the low atmospheric prere on the Mars, but had to evaporate immediately. So here is clear requirement. The history of water at Mars in turn was allowed to encourage new insights over the history of life – whether life forms are found on the planet itself or not.

Before a constriction of the research perspective of astrobiology on the lifelike search for Auberrish life, the space researcher Michael J warned two years ago. Drake from the University of Arizona and Bruce Jakosky, University of Colorado in Boulder (Astrobiology is more than the search for ET): "Yes, we liked to know if we are alone in the universe", Written in an essay for the magazine Nature. "But we need to know how planetary systems form how planets develop, as they look inside, when and how oceans and atmosphere form, and how and why it comes to lifelong environments." They explained exexerably for the Venus, the other neighboring planet of the earth, to investigate more intensively. "What", she asked, "could be more important than the answer to the question of why the earth is so uninhabitable so similar Venus?"

The reminders have fallen on fertile ground: In November 2005, the European space organization ESA wants to start the probe Venus Express, which should circle the planet and examine its atmosphere. Maybe we soon better understand how to develop an extreme greenhouse effect on Venus, which ensures temperatures of about 470 degrees Celsius. These were findings that can be of some significance for the future of life on earth. After all, a global embracing threatens through the amplifying greenhouse effect.

Other space missions trying to complete the puzzle of life through a look into the past. Already in the coming January, the European probe Huygens on the parachute on the Saturnmond Titan is to be sinked and data over its atmosphere. Again, the researchers act the opportunities to find life, as very low. But they hope for fundamental findings over its emergence. For the titanium atmosphere seems to be similarly composed as the atmosphere of the young earth, before developing first life forms. This mission therefore offers the opportunity for the first time to examine the suspected building blocks of life from the close.

In the distance, however, missions such as Darwin, a group of six telescopes, who wants to station the ESA in the middle of the next decade in space to search for earth-tooth planets in other star systems. The sensitivity of the telescopes used today is still too low to recognize planets from the rough of the earth in so coarse distances. Darwin should not only identify them, but even examine their atmosphere spectroscopically and looking for signatures of life. Such a signature goods about the simultaneous presence of oxygen and methane. Since the two gases normally do not tolerate each other, their simultaneous existence is an indication that they are produced steadily – by living beings?

The secret of life on the trail is also the European comet probe Rosetta, the on 26. February your ten-year journey to the comet 67p / Churyumov-Gerasimenko should compete. For at least one year, she should accompany him to the sun at the adoption and the lander "Philae" settle on his surface.

Philae will investigate substances that have remained unnecessary since the development of the solar system. Are the basic building blocks from which the life has formed on earth? Or transport the life itself in the form of microorganisms throughout, such as the British Astrophysician Chandra Wickramasinghe believes from the Cardiff University of Wales (the spread of life in space)?

Even if every single mission processes only one stone in the rough life puzzle: the hope for the one, all decisive find remains. ()
