SkyTour Radio Presents: Mars Special #2 – Lake Discovered
Sunday July 22nd, 2018
In this exciting episode of SkyTour Radio, we delve into the possibilities the latest
discover on Mars has to offer. Recently, we discussed the findings of methane plumes
on the red planet, but now, studies has concluded after much theorizing, the there is
indeed a lake underneath Mars.
As we continue from last week, we compare the atmosphere of Earth to that of Mars,
now with the inclusion of methane, then delve deep into the newly discovered lake,
where we examine what this means for the planets past, present and future and the
opportunities this now gives for us on Earth.
Trace amounts of methane (CH4), at the level of several parts per billion (ppb), were
first reported in Mars’s atmosphere by a team at the NASA Goddard Space Flight Center
in 2003 and in March 2004, the Mars Express Orbiter and ground-based observations by
three groups also suggested the presence of methane in the atmosphere at a concentration
of about 10 ppb (parts per billion)
Large differences in the abundances were measured between observations taken in 2003 and
2006, which suggested that the methane was locally concentrated and probably seasonal.
Previous research found possible signs of intermittent liquid water flowing on the martian
surface, but this is the first sign of a persistent body of water on the planet which
sits under the planet’s south polar ice cap, and is about 20km (12 miles) across.
The discovery was made using Marsis, a radar instrument on board the European Space
Agency’s (Esa) Mars Express orbiter but it could not confirm how thick the layer of water
might be, however the research team estimate that it is a minimum of one metre.
Join us as we explore this fantastic new find and what it means for life on Earth as well
as the possibility of past or future life on Mars.
SkyTour Radio explores the Universe in a down to Earth manner explaining the science we know in fun and bite-sized terms. Science is for everyone and people shouldn’t require an advanced degree to understand as long as it is delivered in an easy to follow way. From Black Holes to Extraterrestrial Life, we will explore the Universe like never before. Join us to check out such things as how stars form, how they live and, how our fate is intertwined with theirs. On the extraterrestrial life front, we will be speaking to the UFO and science arena’s top researchers and bring UFOlogy into the 21st century.
