Detection of DNA in space

If there is life on Mars, it's not so far-fetched to believe that the Martian life may have in common genetic roots of life on Earth.  More than 3.5 billion years ago, a lot of space meteors ricocheted around the solar system, passing the same between the two young planets. This galactic game of ping-pong left its traces on the Earth and on Mars, maybe then creates a common genetic foundation between the two planets.


This theory has great appeal for Christopher Carr, a research scientist in the MIT Department of Earth, Atmospheric and Planetary Sciences.

Carr builds a DNA sequencer, it is hoped that one day they will be sent to Mars, where they will analyze soil and ice samples for traces of DNA and other evidence of life.

DNA sequencing may be of interest in places such as on Jupiter - "Europe" where liquid oceans may harbor signs of life. Even more promising, Carr says, there can be such a place as "Enceladus", a moon of Saturn, scientists believe it could be a potential habitable area and also has a much less intense radiation.


"I think someday we will see the sequencing of DNA in space," says Carr. "Hopefully we'll get a chance to be a part of."
