NASA - National Aeronautics and Space AdministrationWashington, D.C. – The equivalent of 85 billion tons of carbon dioxide — a huge amount equal to three-quarters of the carbon stored in forests across the contiguous United States — is locked in the living vegetation of one African country that holds much of the second largest tropical rainforest in the world, according to new research.

The study conducted by NASA, UCLA and the World Wide Fund for Nature-Germany produced the first high-resolution map of the amount and distribution of carbon stored in the Democratic Republic of Congo (DRC).

NASA’s studying of Earth will help to discover Life on another Planet

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – As a young scientist, Tony del Genio of NASA’s Goddard Institute for Space Studies in New York City met Clyde Tombaugh, the discoverer of Pluto.

“I thought, ‘Wow, this is a one-time opportunity,'” del Genio said. “I’ll never meet anyone else who found a planet.”

That prediction was spectacularly wrong. In 1992, two scientists discovered the first planet around another star, or exoplanet, and since then more people have found planets than throughout all of Earth’s preceding history.

NASA’s Spitzer Space Telescope data shows Super Earth 55 Cancri e could have an Atmosphere similar to Earth’s

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA –  Twice as big as Earth, the super-Earth 55 Cancri e was thought to have lava flows on its surface. The planet is so close to its star, the same side of the planet always faces the star, such that the planet has permanent day and night sides.

Based on a 2016 study using data from NASA’s Spitzer Space Telescope, scientists speculated that lava would flow freely in lakes on the starlit side and become hardened on the face of perpetual darkness. The lava on the dayside would reflect radiation from the star, contributing to the overall observed temperature of the planet.

The super-Earth exoplanet 55 Cancri e, depicted with its star in this artist's concept, likely has an atmosphere thicker than Earth's but with ingredients that could be similar to those of Earth's atmosphere. (NASA)

NASA’s Van Allen Probes mission and FIREBIRD II CubeSat discover Whistling Space Electrons’ Origins

 

Written by Mara Johnson-Groh

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Scientists have long known that solar-energized particles trapped around the planet are sometimes scattered into Earth’s upper atmosphere where they can contribute to beautiful auroral displays.

Yet for decades, no one has known exactly what is responsible for hurling these energetic electrons on their way. Recently, two spacecraft found themselves at just the right places at the right time to witness first hand both the impulsive electron loss and its cause.

NASA’s 2020 Mars Rover Mission tests Parachute Opening at Supersonic Speed

 

Written by Dwayne Brown / Laurie Cantillo
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Landing on Mars is difficult and not always successful. Well-designed advance testing helps. An ambitious NASA Mars rover mission set to launch in 2020 will rely on a special parachute to slow the spacecraft down as it enters the Martian atmosphere at over 12,000 mph (5.4 kilometers per second).

Preparations for this mission have provided, for the first time, dramatic video of the parachute opening at supersonic speed.

The Mars 2020 mission will seek signs of ancient Martian life by investigating evidence in place and by caching drilled samples of Martian rocks for potential future return to Earth.

A 58-foot-tall Black Brant IX sounding rocket launches from NASA's Wallops Flight Facility on Oct. 4. This was the first test of the Mars 2020 mission's parachute-testing series, the Advanced Supersonic Parachute Inflation Research Experiment, or ASPIRE. (NASA/Wallops)

NASA uses Pulsars to detect Gravitational Waves

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – One of the most spectacular achievements in physics so far this century has been the observation of gravitational waves, ripples in space-time that result from masses accelerating in space.

So far, there have been five detections of gravitational waves, thanks to the Laser Interferometer Gravitational-Wave Observatory (LIGO) and, more recently, the European Virgo gravitational-wave detector. Using these facilities, scientists have been able to pin down the extremely subtle signals from relatively small black holes and, as of October, neutron stars.

This computer simulation shows the collision of two black holes, which produces gravitational waves. (SXS)

American Heart Association says Men more likely to receive bystander CPR in public than Women

 

American Heart AssociationAnaheim, CA – Men are more likely to receive bystander CPR in public locations compared to women, and they are more likely to survive after the life-saving measure, according to preliminary research presented at the American Heart Association’s Scientific Sessions 2017, a premier global exchange of the latest advances in cardiovascular science for researchers and clinicians.

Using data from the Resuscitation Outcomes Consortium, a network of regional clinical centers in the United States and Canada studying out-of-hospital treatments of cardiac arrest and trauma, researchers analyzed 19,331 cardiac events in the home and in public.

Hands-Only CPR has just two easy steps: If you see a teen or adult suddenly collapse, (1) Call 9-1-1 and (2) Push hard and fast in the center of the chest to the beat of the disco song “Stayin’ Alive.” The American Heart Association’s Hands-OnlyTM CPR at this beat can more than double or triple a person’s chances of survival.

NASA to test CubeSat Weather Satellite

 

Written by Samson Reiny
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Behind every weather forecast—from your local, five-day prediction to a late-breaking hurricane track update—are the satellites that make them possible. Government agencies depend on observations from weather satellites to inform forecast models that help us prepare for approaching storms and identify areas that need evacuating or emergency first responders.

Weather satellites have traditionally been large, both in the effort needed to build them and in actual size. They can take several years to build and can be as big as a small school bus. But all of that could change in the future with the help of a shoebox-sized satellite that will start orbiting Earth later this month.

The Microwave Radiometer Technology Acceleration (MiRaTA) satellite, a 3U CubeSat, is shown with solar panels fully deployed, flanking the body of the spacecraft, which has a circular aperture at the top for the microwave radiometer antenna, used for atmospheric science measurements. There are also two small, thin tape-measure antennas on the top, used for UHF radio communication with the ground station. (MIT Lincoln Laboratory)

NASA’s Orion spacecraft to undergo design test of Launch Abort System in April 2019

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Orion spacecraft is scheduled to undergo a design test in April 2019 of the capsule’s launch abort system (LAS), which is a rocket-powered tower on top of the crew module built to very quickly get astronauts safely away from their launch vehicle if there is a problem during ascent.

This full-stress test of the LAS, called Ascent Abort Test 2 (AA-2), will see a booster, provided by Orbital ATK, launch from Cape Canaveral Air Force Station in Florida, carrying a fully functional LAS and a 22,000 pound Orion test vehicle to an altitude of 32,000 feet at Mach 1.3 (over 1,000 miles an hour).

NASA will test Orion’s launch abort system in high-stress ascent conditions during an April 2019 test called Ascent Abort-2. (NASA)
