NASA’s Aura satellite celebrates it’s 10th Year analyzing Earth’s Climate System

 

Written by Alan Buis

NASA - National Aeronautics and Space AdministrationPasadena, CA – Nitrogen and oxygen make up nearly 99 percent of Earth’s atmosphere. The remaining one percent is comprised of gases that — although present in small concentrations — can have a big impact on life on Earth.

Trace gases called greenhouse gases warm the surface, making it habitable for humans, plants and animals. But these greenhouse gases, as well as clouds and tiny particles called aerosols in the atmosphere, also play vital roles in Earth’s complex climate system.

NASA’s Low-Density Supersonic Decelerator (LDSD) completes Test Flight

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The balloon launch occurred at 8:45am HST (11:45am PDT/3:45pm CDT) from the U.S. Navy’s Pacific Missile Range Facility in Kauai, Hawaii. At 11:05am HST (2:05pm PDT/6:05pm CDT), the test vehicle dropped away from the balloon (as planned), and powered flight began.

The balloon and test vehicle were about 120,000 feet over the Pacific Ocean at the time of the drop. The vehicle splashed down in the ocean at approximately 11:35am HST (2:35pm PDT/6:35pm CDT), after the engineering test flight concluded.

NASA’s Orion Spacecraft’s primary modules stacked in preparation for Launch

 

Written by Rachel Kraft
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – With just six months until its first trip to space, NASA’s Orion spacecraft continues taking shape at the agency’s Kennedy Space Center in Florida.

Engineers began stacking the crew module on top of the completed service module Monday, the first step in moving the three primary Orion elements –crew module, service module and launch abort system – into the correct configuration for launch.

The Orion crew module for Exploration Flight Test-1 is shown in the Final Assembly and System Testing (FAST) Cell, positioned over the service module just prior to mating the two sections together. The FAST cell is where the integrated crew and service modules are put through their final system tests prior to rolling out of the Operations and Checkout Building at NASA's Kennedy Space Center in Florida for integration with its rocket.

Tennessee Department of Health is raising Awareness about Chikungunya

 

Tennessee Department of Health - TDOHNashville, TN – The Tennessee Department of Health is investigating the first potential cases of chikungunya in the state. Multiple people from Tennessee recently traveled to the Caribbean, where the illness is now a widespread epidemic with over 100,000 suspected cases.

Some of the recent travelers from Tennessee now have symptoms of the illness.

Chikungunya is transmitted by daytime biting mosquitoes.

NASA’s Space Technology Mission Directorate (STMD) investigates technologies for Human, Robotic missions to Mars

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Space Technology Mission Directorate (STMD) is paving the way for future Mars exploration. The directorate is currently investing in and developing bold, disruptive technology required for future deep-space missions.

This critical work leads a concerted effort throughout the agency, including at the program level and across multiple centers, as well as with partners in American industry.

During its first free flight test at night, Morpheus (a Human Exploration and Operations MD project) tests NASA's ALHAT and an engine that runs on liquid oxygen and methane, which are green propellants. These capabilities could be used in the future to deliver cargo to planetary surfaces.

NASA’s Jason-2 satellite data points to possible El Niño in 2014

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Every ten days, the NASA/French Space Agency Jason-2 satellite maps all the world’s oceans, monitoring changes in sea surface height, a measure of heat in the upper layers of the water. Because our planet is more than 70% ocean, this information is crucial to global forecasts of weather and climate.

Lately, Jason-2 has seen something brewing in the Pacific—and it looks a lot like 1997.

NASA prepares Low-Density Supersonic Decelerator Saucer craft for Flight Test

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Low-Density Supersonic Decelerator (LDSD) project, a rocket-powered, saucer-shaped test vehicle, has completed final assembly at the U.S. Navy’s Pacific Missile Range Facility in Kauai, Hawaii.

This experimental flight test is designed to investigate breakthrough technologies that will benefit future Mars missions, including those involving human exploration. Three weeks of testing, simulations and rehearsals are planned before the first launch opportunity on the morning of June 3rd. LDSD was built at NASA’s Jet Propulsion Laboratory, Pasadena, California, and shipped to Kauai for final assembly and preparations.

NASA Ames Research Center

NASA - National Aeronautics and Space AdministrationMountain View, CA – NASA’s Global Hawk research aircraft returned to its base at NASA’s Armstrong Flight Research Center at Edwards Air Force Base, CA, early Friday morning March 14th, marking the completion of flights in support of this year’s Airborne Tropical Tropopause Experiment (ATTREX), a multi-year NASA airborne science campaign.

On February 13th, the autonomously operated aircraft began conducting science flights from Andersen Air Force Base on Guam in the western Pacific region on a mission to track changes in the upper atmosphere and help researchers understand how these changes affect Earth’s climate.

NASA reports Orion Spacecraft construction, testing ahead of schedule

 

NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Orion is marching ever closer to its first trip to space on a flight that will set the stage for human exploration of new destinations in the solar system.

The Orion team continues to work toward completing the spacecraft to be ready for a launch in September-October.  However, the initial timeframe for the launch of Exploration Flight Test-1 (EFT-1) has shifted from September-October to early December to support allowing more opportunities for launches this year.

Engineers prepare Orion’s service module for installation of the fairings that will protect it during launch this fall when Orion launches on its first mission. The service module, along with its fairings, is now complete. (NASA)

NASA uses satellites, aircraft, and high-altitude balloons to investigate California’s extreme drought

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – California is supposed to be the Golden State.  Make that golden brown.

The entire west coast of the United States is changing color as the deepest drought in more than a century unfolds.  According to the U.S. Department of Agriculture and NOAA, dry conditions have become extreme across more than 62% of California’s land area—and there is little relief in sight.
