NASA Twin Otter aircraft in flight over northern Ohio. The aircraft has been utilized for numerous research projects conducted at NASA Glenn Research Center in Cleveland, Ohio.

Aircraft mechanics reposition the Twin Otter after a research flight. The aircraft was used to gather data from Lake Erie for the Algae Bloom Project.

An otter makes its way into the underbrush at NASA's Kennedy Space Center in Florida. The center shares a border with the Merritt Island National Wildlife Refuge. More than 330 native and migratory bird species, 25 mammals, 117 fishes and 65 amphibians and reptiles call Kennedy and the wildlife refuge home.

The Lockheed Viking S-3B aircraft is being pulled out of the hangar at Glenn Research Center in preparation for its departure and retirement from service. This former NAVY aircraft was the last such aircraft still flying. It has gone to a museum on the west coast. After leaving service with the NAVY, it came to GRC to be used in aircraft icing experiments. The swept wings made it suitable for such research as opposed to the straight wings on GRG’s other icing research aircraft, the De Havilland Twin Otter.

Endeavour, Orbiter Vehicle (OV) 105, roll out to KSC Launch Complex Pad 39B

S92-34862 (13 March 1992) --- An otter, surprised by the unexpected presence of the photographer, seems unaware of the Space Shuttle Endeavour rolling behind it to Launch Pad 39B. Endeavour is the newest orbiter in the Shuttle fleet. Still ahead for Endeavour (OV-105) is a Flight Readiness Firing of its three main engines, and the Terminal Countdown Demonstration Test with the flight crew. Endeavour's maiden voyage on NASA's mission STS-49 will occur in late spring.

KENNEDY SPACE CENTER, FLA. -- Astronaut Nicole Stott is one of three astronauts taking part in the 17-day NASA Extreme Environment Mission Operations (NEEMO) project from the National Oceanic and Atmospheric Administration (NOAA) Aquarius Underwater Laboratory. At left is NEEMO instructor "Otter" Mark Rutten. The astronauts are testing space medicine concepts and moon-walking techniques. The 45-foot-long, 13-foot-diameter complex is three miles off Key Largo in the Florida Keys National Marine Sanctuary and anchored 62 feet below the surface. Canadian astronaut Dave Williams is leading the undersea mission, along with Stott and astronaut Ron Garan. Dr. Tim Broderick of the University of Cincinnati rounds out the crew.

NASA Airborne Campaigns Focus on Climate Impacts in the Arctic

Credit: Chris Larsen, University of Alaska-Fairbanks Over the past few decades, average global temperatures have been on the rise, and this warming is happening two to three times faster in the Arctic. As the region’s summer comes to a close, NASA is hard at work studying how rising temperatures are affecting the Arctic. NASA researchers this summer and fall are carrying out three Alaska-based airborne research campaigns aimed at measuring greenhouse gas concentrations near Earth’s surface, monitoring Alaskan glaciers, and collecting data on Arctic sea ice and clouds. Observations from these NASA campaigns will give researchers a better understanding of how the Arctic is responding to rising temperatures. The Arctic Radiation – IceBridge Sea and Ice Experiment, or ARISE, is a new NASA airborne campaign to collect data on thinning sea ice and measure cloud and atmospheric properties in the Arctic. The campaign was designed to address questions about the relationship between retreating sea ice and the Arctic climate. Arctic sea ice reflects sunlight away from Earth, moderating warming in the region. Loss of sea ice means more heat from the sun is absorbed by the ocean surface, adding to Arctic warming. In addition, the larger amount of open water leads to more moisture in the air, which affects the formation of clouds that have their own effect on warming, either enhancing or reducing it.
