NASA study reveals Oceans Temperature Rise Slowed

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new NASA study of ocean temperature measurements shows that in recent years, extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans. Researchers say this shifting pattern of ocean heat accounts for the slowdown in the global surface temperature trend observed during the past decade.

Researchers Veronica Nieves, Josh Willis and Bill Patzert of NASA’s Jet Propulsion Laboratory, Pasadena, California, found a specific layer of the Indian and Pacific oceans between 300 and 1,000 feet (100 and 300 meters) below the surface has been accumulating more heat than previously recognized.

NASA uses AVIRIS-NG instrument to map California Oil Pipeline Spill Beach Tar

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – When an on-land pipeline ruptured north of Santa Barbara, California, on May 19th — spilling 105,000 barrels of crude oil onto Refugio State Beach and about 21,000 gallons of oil into the Pacific Ocean in the north Santa Barbara Channel — it created an environmental nightmare for local beaches and wildlife.

In support of the response to the Refugio Incident, as it is known, NASA deployed a De Havilland Twin Otter aircraft carrying a unique airborne instrument developed by NASA’s Jet Propulsion Laboratory, Pasadena, California, to study the spill and test the ability of imaging spectroscopy to map tar on area beaches. The work is advancing our nation’s ability to respond to future oil spills.

NASA’s Low-Density Supersonic Decelerator (LDSD) completes second test flight with flying colors

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Engineers are poring over the data following the second experimental landing technology test of NASA’s Low-Density Supersonic Decelerator (LDSD) project. The saucer-shaped LDSD craft splashed down at 11:49am HST (2:49 PDT/5:49pm EDT) Monday in the Pacific Ocean off the west coast of the Hawaiian island of Kauai.

During this flight, the project team tested two decelerator technologies that could enable larger payloads to land safely on the surface of Mars, and allow access to more of the planet’s surface by assisting landings at higher-altitude sites.

NASA’s Low-Density Supersonic Decelerator (LDSD) test to be broadcast Live on NASA Ustream channel

NASA - National Aeronautics and Space AdministrationPasadena, CA – Since Orville Wright first took to the skies over Kitty Hawk, North Carolina, experimental flight tests have been a relatively singular affair, with aviators taking their untried machines into the sky in search of good data and a great hangar story.

But nowadays, cutting-edge testing of air and space machines has become somewhat more accessible. This week offers up another opportunity to witness an important milestone in experimental flight tests.

NASA’s Low-Density Supersonic Decelerator (LDSD) second test flight set for Tuesday, June 2nd

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The second flight test of NASA’s Low-Density Supersonic Decelerator (LDSD) now will launch no earlier than 10:30am PDT (1:30pm EDT, or 7:30am HST) Tuesday, June 2nd, from the U.S. Navy’s Pacific Missile Range Facility (PMRF) on Kauai, Hawaii. NASA Television coverage will begin at 10:00am PDT (1:00pm EDT, or 7:00am HST).

To accommodate prevailing weather conditions, mission managers moved the launch window one hour earlier to increase the probability of LDSD launching on time.

NASA reports Jason-3 satellite set to launch in July

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – You can’t predict the outcome of a marathon from the runners’ times in the first few miles. You’ve got to see the whole race. Global climate change is like that: You can’t understand it if all you have is a few years of data from a few locations. That’s one reason that a fourth-generation satellite launching this summer is something to get excited about.

Jason-3, a mission led by the National Oceanic and Atmospheric Administration that is currently scheduled to launch on July 22nd, is the latest in a series of U.S.-European satellite missions that have been measuring the height of the ocean surface for 23 years.

NASA’s Orion spacecraft test flight data used to prepare for future missions

 

NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Orion spacecraft continues on the agency’s journey to Mars as engineers analyze data from the spacecraft’s December flight test and make progress developing and building the spacecraft for its first mission atop NASA Space Launch System (SLS) heavy-lift rocket. On future missions, Orion will send astronauts to an asteroid and onward toward the Red Planet.

At machine houses across the country, elements of the primary structure for the next Orion to fly in space are coming together. Avionics components are being built and simulators for the ESA (European Space Agency)-built service module that will house the spacecraft’s propulsion and solar arrays are being delivered.

NASA monitors Severe Holiday Weather from Space

 

Written by Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Severe weather in the form of tornadoes is not something people expect on Christmas week but a storm system on December 23rd brought tornadoes to Mississippi, Georgia and Louisiana. As the storm moved, NASA’s RapidScat captured data on winds while NOAA’s GOES satellite tracked the movement of the system.

NASA’s RapidScat instrument flies aboard the International Space Station and captured a look at some of the high winds from the storms that brought severe weather to the U.S. Gulf Coast on December 23rd. In addition, an animation of images from NOAA’s GOES-East satellite showed the movement of those storms and other weather systems from Canada to South America from December 21st to 24th.
