Conceptual Design of a South Pole Carrier Pigeon UAV
<p>Currently, the South Pole has a large data problem. It is estimated that 1.2 TB of data is being produced every day, but less than 500 GB of that data is being uploaded via aging satellites to researchers in other parts of the world. This requires those at the South Pole to analyze the data and …

A Carrier-Pigeon UAS for South Pole Data Transfer
… support hardware-based data transfer from South Pole Station in Antarctica to a location of high connectivity has been undertaken. Due to the specific location of the Amundsen-Scott South Pole station and competing demands from other governmental agencies, satellite connectivity …

Crater ice deposits near the south pole of Mars
Layered deposits atop both Martian poles are thought to preserve a record of past climatic conditions in up to three km of water ice and dust. Just beyond the extent of these south polar layered deposits (SPLD), dozens of impact craters contain large mounds of fill material with distinct …

Feasibility of acoustic neutrino detection with the South Pole Acoustic Test Setup
… The optically transparent ice at the geographic South Pole has optical attenuation lengths in the order of 100m. This has allowed the construction and operation of the kilometer-scale neutrino detector, IceCube. However, the optical attenuation length and therefore detector cost is prohibitive to …

LIDAR Studies of the Middle Atmosphere Temperatures and Iron Layer at South Pole
Similar to the Na observations at South Pole in 1995--1997, the seasonal variations in Fe column abundance, height, and width exhibit a strong annual cycle. The Fe and Na densities exhibit strong 12-month oscillations with the amplitudes comparable to the background level, resulting in extremely …

Gravity Wave Characteristics in the Troposphere, Lower Stratosphere, and Mesopause at the South Pole
… from high-resolution balloon soundings at the South Pole is combined with three years (1995-1997) of mesospheric Na lidar measurements to examine the characteristics of gravity waves at the South Pole. Studies examine the troposphere, lower-stratosphere, and mesopause. It is found that wave …

Middle atmosphere structure and dynamics: Lidar studies at the South Pole, Syowa and Urbana
… observations of the middle atmosphere at the South Pole (90$\sp\circ$S), Syowa (69$\sp\circ$S, 39$\sp\circ$E), and Urbana (88$\sp\circ$W, 40$\sp\circ$N). The South Pole stratospheric observations yield a high resolution data set of stratospheric temperature and polar stratospheric cloud (PSC) …

On the Variation of Gravity Wave Activity through the Solar Cycle at the South Pole
… in solar energy over the solar cycle at the South Pole. The different types of atmospheric waves interact with each other in complex manners that are still a subject of research today. Gravity waves are known to be modulated by solar tides and vice versa so a change in the tides will induce a …

From Lunar Modules to In-Situ Habs: Conceptualization & Considerations of a Developing Lunar South Pole Base
… of how an example base at the Lunar south pole could take advantage of topography, local resources, and new construction technologies as it undergoes this infrastructural transition. Such pursuits are critical because future large-scale telerobotic ISRU activities (among many other …

From Gondwanaland, with love : the tale of how Boston got its rocks
… They formed about 600 million years ago, at the South Pole, as the northern coast of a supercontinent called Gondwanaland. Boston's journey from the South Pole to its current location traces the world's geologic history over that period of time, including the emergence of animal life as we know …

Design of an HF transmit antenna for bistatic ionospheric soundings in Antarctica
… events which affect the earth's climate. The South African National Space Agency (SANSA) plans to install a low-powered high frequency (HF) transmitter at the South Pole for use in a bistatic ionospheric sounding system intended to detect such TIDs. The aim of this dissertation was to design a …

Broadband, millimeter-wave antireflection coatings for cryogenic sintered aluminum oxide optics
… the third generation survey camera on board the South Pole Telescope (SPT-3G; Benson et al., 2014}). SPT is located at the geographic South Pole (elevation ~2800 m), which is an exceptionally arid environment (Radford and Holdaway, 1998; Radford, 2011). A fifty year study of precipitable water …

Investigation of regional variation in Lunar crater morphometry from (Lunar Orbiter Laser Altimeter) LOLA observations
… far side highlands, near side highlands, and South Pole-Aitken basin are decomposed into 50 elevation profiles, from which key geometric crater properties are extracted. The geometric properties and their respective standard variation, such as height-to-diameter ratios, and average elevation …

Infrared-Bright Active Galactic Nuclei in Massive Galaxy Clusters
… mass-selected galaxy cluster sample from the South Pole Telescope spanning a redshift range of 0.15 ≲ z ≲ 1.7 for which we have acquired follow-up Spitzer Space Telescope observations. With these data we explore the incidence of IR-bright AGN in clusters as a function of cluster mass, …

Self assembling magnetic tiles
… 48 tiles that had the same proportion of north-pole and south-pole facing magnets. The difference between the two 3D shapes created is a direct result of the magnet tile sequencing, only. To connect the tiles, two different types of connectors were designed: one rigid and one flexible.
