The GRIPS scientific payload hangs suspended over the frozen surface of McMurdo Station's Long Duration Balloon field as one of launch crew looks on.

GRIPS' Moment Under the Sun
Science / Space and Atmospheric Physics
Wednesday October 05, 2016
As a giant helium balloon lifted the alabaster solar telescope GRIPS (Gamma-Ray Imager/Polarimeter for Solar Flares) aloft, the excitement on the ground was palpable. The team of researchers, who had spent seven years working on the project, jumped for joy and snapped photos of their experiment in the air for the first time.

A little ways away from the South Pole station, the Keck Array is shielded from interference reflected up from the ground behind a protective shroud.

Searching for Inflation
Science / Space and Atmospheric Physics
Monday August 01, 2016
Scientists working at the South Pole are trying to detect the imprints of gravitational waves from when the universe was only a tiny fraction (about one trillionth of a trillionth of a trillionth) of a second old. But first, they have to finish clearing away the galactic dust obscuring their view.

Apr 04 2016	Science / Space and Atmospheric Physics The Stuff Between the Stars Four years ago, scientists set up the High Elevation Antarctic Terahertz (HEAT) telescope in the middle of the high Antarctic plateau, more than 500 miles from the South Pole. The harsh environment and unique atmospheric conditions here make it one of the best places on Earth to study the cosmos.
Feb 09 2016	Science / Space and Atmospheric Physics A New Home for an Old Experiment The longest running experiment at McMurdo is leaving the station, but it's not moving too far away, Antarctically speaking. The CosRay experiment, which has been recording changes in the stream of cosmic rays striking Earth since 1960, is relocating to the new South Korean station, Jang Bogo, about 230 miles away.
Apr 27 2015	Science / Space and Atmospheric Physics A Sticky Problem A telescope launched 35 kilometers into the stratosphere above Antarctica had a singular mission: to detect the impossibly faint signal from when the universe expanded faster than the speed of light, a theory known as cosmological inflation.
Jun 26 2014	Science / Space and Atmospheric Physics Joining Together The South Pole Telescope has been involved in investigating some of the greatest mysteries of the universe. Now the powerful instrument in Antarctica will be used to form an Earth-sized telescope to study a black hole in the center of the Milky Way Galaxy.
Jun 20 2014	Science / Space and Atmospheric Physics Global Effort The South Pole and McMurdo SuperDARN radars are part of a global network tracking the sun's interaction with the Earth's upper atmosphere to better understand so-called space weather.
Mar 18 2014	Science / Space and Atmospheric Physics Clear Signal Researchers with the BICEP2 collaboration recently announced that their telescope in Antarctica has allowed them to collect what they believe is the first direct evidence for cosmic inflation.
Dec 20 2013	Science / Space and Atmospheric Physics Major Upgrade Austral summers are not as exciting now as they once were when the IceCube Neutrino Observatory was under construction at the South Pole Station. But quality data collection still depends on how much can be done during the brief summer. This one will be especially busy with a major upgrade under way.
Dec 11 2013	Science / Space and Atmospheric Physics From a Galaxy Far, Far Away Researchers with the IceCube collaboration have announced that a National Science Foundation (NSF)-built detector at the Amundsen-Scott South Pole Station allowed them to observe 28 very high-energy neutrinos that constitute the first solid evidence for astrophysical neutrinos from cosmic accelerators such as black holes.
Nov 07 2013	Science / Space and Atmospheric Physics A Bigger Mousetrap To catch the elusive subatomic particles called neutrinos is not just a matter of building a better mousetrap. You need a really, really BIG mousetrap. Scientists at the South Pole hope to construct a 100-square-kilometer neutrino detector to capture the highest energy neutrinos theorized to exist.
Sep 27 2013	Science / Space and Atmospheric Physics Opposite Ends When solar wind lashes the Earth's upper atmosphere, the polar regions react with a brilliant light show known as auroras. But do the ends of the Earth react similarly? Scientists are installing an array of instruments in remote East Antarctica to find out.
Sep 20 2013	Science / Space and Atmospheric Physics New Mode of Discovery Scientists using the South Pole Telescope became the first team to detect a long-predicted polarization pattern in the afterglow of the Big Bang. The detection of this signal is a milestone along the way toward understanding cosmic inflation, the period of extremely rapid expansion of the universe.
Sep 13 2013	Science / Space and Atmospheric Physics Coming Out on Top A study by researchers using data from the IceCube Neutrino Observatory at the South Pole reveals new information that may help unravel the longstanding mystery about the origins of cosmic rays. The research draws on data collected by IceCube's surface array called IceTop.
Apr 25 2013	Science / Space and Atmospheric Physics Energetic Excitement News emerged this week that scientists with the IceCube Neutrino Observatory likely captured evidence of the two highest-energy neutrinos ever observed.
