There's every reason to think we could discover many more such briny spots deep underneath the Martian south polar cap
(1969) reported mean polar cap
boundaries for 1905-1965.
So when they're not preventing nuclear wars or asteroid deflecting They'll plug the holes in the ozone layer or Keep the polar cap
from melting So let's just show some gratitude and all say: "ThanKs a million." To these worthy extra-terrestrials who Keep our world from oblivion Then pull a pint of Landlord and prepare a flowing toast To Venusians and Tim Taylor's Ales; the DRINK they liKe the most.
Di Giovanni appeared in the 2012 December Journal, which sought to correlate polar cap
recession rate with solar activity.
Roger Phillips of the Southwest Research Institute in Boulder, Colo., and his colleagues base their findings on radar studies by the Mars Reconnaissance Orbiter of the layered deposits at Mars' south polar cap
. Earlier studies had indicated that a veneer of frozen carbon dioxide sits atop part of the cap with a thin layer of water ice beneath it.
Oil drilling and mining, new shipping routes and tourism, and easier fishing activity are some of the issues creating interest in the Arctic as the polar cap
shrinks, while simultaneously building tension among rim countries.
Z(0, [alpha]) is a North polar cap
, that is a spherical cap with center the North pole, and Z([alpha], [pi]) is a South polar cap
These conditions are consistent with observed polar cap
erosion and may even influence the triggering of large dust storms.
A telescope with an aperture of four inches or more will reveal surface details of Mars, including the glistening south polar cap
- currently tilted towards to the Earth - and dark markings normally only seen on the Hubble space telescope photos.
Locations closer to the polar cap
are covered with the relatively young polar layered deposits.
Watkins, and headed for the polar cap
to Camp Opal, another scientific research center aboard the submarine USS Trepang (SSN 674).
It's hard to imagine the desolate beauty of a frigid continent that is larger than both the USA and Mexico combined, 98 per cent of which is covered in ice more than 1.5 kilometres thick, with a polar cap
containing 70 per cent of the world's flesh water.
