View Full Version : Mars Express Confirms Methane Discovery

2005-Sep-14, 01:31 PM
SUMMARY: The European Space Agency has confirmed reports that Mars Express has measured methane in the Martian atmosphere. The presence of methane - 10 parts per billion - was confirmed using the spacecraft's Planetary Fourier Spectrometer (PFS), which can detect the chemical in trace amounts. This isn't a lot of methane, but it has to be produced by some ongoing process such as volcanoes... or by life. The spacecraft will continue to measure the presence of methane in the atmosphere, mapping out the planet to find where it's concentrated. This will help to confirm or rule out volcanic gasses.
