I\u2019ve met ecologists who are studying lakes in the Dry Valleys, geologists mapping the crater of Mt. Erebus (an active volcano on Ross Island!), and glaciologists planning for work at the South Pole. Yesterday, Rachel and I met a planetary scientist who is developing a <a href=\"http:\/\/schmidt.eas.gatech.edu\/simple\/\">prototype for a robot <\/a>that could explore beneath the ice of Europa.<\/p>\n<p>Europa is an ice-coated moon of Jupiter, with a cracked surface and a little jiggle to its rotation suggestive of liquid water beneath a thick frozen layer. It\u2019s a primary target for finding signatures of life in our solar system. I think it\u2019s even more exciting than Mars in that respect, but I\u2019m no planetary scientist.<\/p>\n<p>The Europa team, led by Dr. Britney Schmidt, has done an absolutely incredible amount of engineering and field-testing to develop an autonomous underwater vehicle (AUV) capable of exploring beneath the ice. Antarctica\u2014specifically the several-hundred-meter-thick ice shelves surrounding much of the coastline\u2014is the closest thing we have to Europa on Earth. So, Schmidt is here, deploying her new instrument down a hole drilled right through the ice shelf and into the frigid water below.<\/p>\n<div id=\"attachment_92\" style=\"width: 594px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/blogs.uml.edu\/antarctica-2015\/wp-content\/uploads\/sites\/36\/2015\/10\/DSCN1224.jpg\"><img aria-describedby=\"caption-attachment-92\" loading=\"lazy\" class=\"size-large wp-image-92\" src=\"http:\/\/blogs.uml.edu\/antarctica-2015\/wp-content\/uploads\/sites\/36\/2015\/10\/DSCN1224-1024x768.jpg\" alt=\"The Artemis robot, hanging out with it's science hat up.

It\u2019s got a little hat that pops up out of the main body to nestle up against the base of the ice shelf and determine if proteins are present. It maps out the seafloor topography, which we can\u2019t do without robots like this. And it knows where it is, even without using GPS, through use of some fancy gyroscope that uses the planet\u2019s axis of rotation as guidance. The robot (it\u2019s named Artemis) has to do its thing without input from humans, so it needs to be able to navigate back to its entry hole. Once it\u2019s close to the hole, it homes in on a cylindrical flashing blue LED beacon and slots into a cable attached to the cylinder. Then the cable pulls it up out of the drill hole so it can talk to whatever instrument will receive its data. It\u2019s super awesome. Just getting to hang out with scientists working on these sorts of projects is a fabulous learning experience.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>There are a thousand or so scientists and support staff at McMurdo station during the summer months, so you might expect that there\u2019re some pretty awesome projects going on.
