A close-up image of the crack spreading across the ice shelf of Pine Island Glacier shows the details of the boulder-like blocks of ice that fell into the rift when it split. For most of the 18-mile stretch of the crack that NASA’s DC-8 flew over on Oct. 26, 2011, it stretched about 240 feet wide, as roughly seen here. The deepest points ranged from about 165 to 190 feet, roughly equal to the top of the ice shelf down to sea level. Scientists expect the crack to propagate and the ice shelf to calve an iceberg of more than 300 square miles in the coming months. This image was captured by the Digital Mapping System (DMS) aboard the DC-8.

NASA's DC-8, outfitted with seven remote-sensing instruments, and a Gulfstream 5 operated by the National Science Foundation and National Center for Atmospheric Research and outfitted with a high-altitude laser-ranging mapper, will fly from Chile over Antarctica in October and November.

The Space Shuttle Discovery takes off from Launch Pad 39B at the Kennedy Space Center, Florida, to being Mission STS-26 on 29 September 1988,11:37:00 a.m. EDT. The 26th shuttle mission lasted four days, one hour, zero minutes, and 11 seconds. Discovery landed 3 October 1988, 9:37:11 a.m. PDT, on Runway 17 at Edwards Air Force Base, California. Its primary payload, NASA Tracking and Data Relay Satellite-3 (TDRS-3) attached to an Inertial Upper Stage (IUS), became the second TDRS deployed. After deployment, IUS propelled the satellite to a geosynchronous orbit. The crew consisted of Frederick H. Hauck, Commander; Richard O. Covey, Pilot; John M. Lounge, Mission Specialist 1; George D. Nelson, Mission Specialist 2; and David C. Hilmers, Mission Specialist 3.

The team for NASA's BARREL – short for Balloon Array for Radiation belt Relativistic Electron Losses -- mission returned from Antarctica in March 2014. BARREL's job is to help unravel the mysterious Van Allen belts, two gigantic donuts of radiation that surround Earth, which can shrink and swell in response to incoming energy and particles from the sun and sometimes expose satellites to harsh radiation. While in Antarctica, the team launched 20 balloons carrying instruments that sense charged particles that are scattered into the atmosphere from the belts, spiraling down the magnetic fields near the South Pole. Each balloon traveled around the pole for up to three weeks.

BARREL researchers get ready to release the top part of the balloon, called the bubble, as it fills with enough helium to support itself. Only the top part of the balloon is inflated before launch since the helium expands as the balloon ascends.
