NASA Developing Technology to Land on other Planets with rough Terrain

NASA - National Aeronautics and Space AdministrationPasadena, CA – Canyons, craters and cracked ice fields on other worlds might be hiding exciting scientific discoveries. But how do we get spacecraft to land on dangerous, uneven terrain?

A new NASA video explains how cutting-edge technologies could help. A system called the CoOperative Blending of Autonomous Landing Technologies (COBALT) is being developed in the Mojave Desert, with participation from several partners, including NASA’s Jet Propulsion Laboratory in Pasadena, California.

A rocket flying several landing technologies was recently flown in the Mojave Desert. These flight tests, coordinated by NASA, are helping to develop technology for precise landings in uneven terrain. (NASA/JPL-Caltech)

NASA research shows Smoke from Wildfires can Impact Climate more than previously thought

 

Written by Joe Atkinson

NASA - National Aeronautics and Space AdministrationHampton, VA – The 2017 wildfire season is well underway in the United States with thousands of acres scorched already in Georgia and Florida alone, according to the National Park Service. New research using data collected during NASA airborne science campaigns shows how smoke from this type of wildfire worldwide could impact the atmosphere and climate much more than previously thought.

The study, led by researchers at the Georgia Institute of Technology, found brown carbon particles released into the air from burning trees and other organic matter are much more likely than previously thought to travel to the upper levels of the atmosphere, where they can interfere with rays from the sun – sometimes cooling the air and at other times warming it.

NASA’s Convective Processes Experiment (CPEX) will try to improve Weather Forecasts

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A NASA-funded field campaign getting underway in Florida on May 25th has a real shot at improving meteorologists’ ability to answer some of the most fundamental questions about weather: Where will it rain? When? How much?

Called the Convective Processes Experiment (CPEX), the campaign is using NASA’s DC-8 airborne laboratory outfitted with five complementary research instruments designed and developed at NASA.

The plane also will carry small sensors called dropsondes that are dropped from the plane and make measurements as they fall.

NASA explores using Nanotechnology for Aerospace Applications

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Mastering the intricacies of controlling matter at the nanoscale level is part of a revolutionary quest to apply nanotechnology to benefit industrial processes. A key element of that technology is the use of carbon nanotubes.

Carbon nanotubes are small hollow tubes with diameters of 0.7 to 50 nanometers and lengths generally in the tens of microns. While ultra-small, carbon nanotubes offer big-time attributes.

For instance, materials can be manufactured that exhibit superior strength but are still extremely lightweight. Think in terms of 200 times the strength and five times the elasticity of steel. For good measure, add in that they offer highly-efficient electrical and thermal conductivity.

NASA Innovative Advanced Concepts selects 22 proposals for advancement

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A mechanical rover inspired by a Dutch artist. A weather balloon that recharges its batteries in the clouds of Venus.

These are just two of the five ideas that originated at NASA’s Jet Propulsion Laboratory in Pasadena, California, and are advancing for a new round of research funded by the agency.

In total, the space agency is investing in 22 early-stage technology proposals that have the potential to transform future human and robotic exploration missions, introduce new exploration capabilities, and significantly improve current approaches to building and operating aerospace systems.

NASA’s Earth Science continues research from International Space Station

 

Written by Samson Reiny
NASA Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The number of instruments on the International Space Station dedicated to observing Earth to increase our understanding of our home planet continues to grow.

Two new instruments are scheduled to make their way to the station on the SpaceX Dragon capsule.

The Stratospheric Aerosol and Gas Experiment (SAGE) III instrument will monitor the condition of the ozone layer, which covers an area in the stratosphere 10 to 30 miles (16 to 48 kilometers) above Earth and protects the planet from the sun’s harmful ultraviolet radiation.

NASA to send Stratospheric Aerosol and Gas Experiment III (SAGE III) to International Space Station

 

Written by Eric Gillard
NASA Langley Research Center

NASA - National Aeronautics and Space AdministrationHampton, VA – Brooke Thornton has devoted eight years to a project that aims to check on the atmospheric health of the Earth. Needless to say, when NASA’s Stratospheric Aerosol and Gas Experiment III on the International Space Station (SAGE III on ISS) launches, she’ll be among the many cheering and working for its success in space.

“After seeing SAGE III mature from concept, to development, to assembly and testing, and preparing for mission ops … I’m excited to see it launch so we get the science we have worked so hard for,” she said.

NASA - National Aeronautics and Space AdministrationWashington, D.C. – In 2016, NASA drove advances in technology, science, aeronautics and space exploration that enhanced the world’s knowledge, innovation, and stewardship of Earth.

“This past year marked record-breaking progress in our exploration objectives,” said NASA Administrator Charles Bolden. “We advanced the capabilities we’ll need to travel farther into the solar system while increasing observations of our home and the universe, learning more about how to continuously live and work in space, and, of course, inspiring the next generation of leaders to take up our Journey to Mars and make their own discoveries.”

NASA’s CYGNSS Microsatellites to give unprecedented measurements of Tropical Storms, Hurricanes

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA confirmed Friday morning that all eight spacecraft of its latest Earth science mission are in good shape. The Cyclone Global Navigation Satellite System (CYGNSS) will provide scientists with advanced technology to see inside tropical storms and hurricanes as never before.

CYGNSS launched into orbit at 5:37am PST (8:37am EST) Thursday aboard an Orbital ATK air-launched Pegasus XL launch vehicle. The rocket was dropped and launched from Orbital’s Stargazer L-1011 aircraft, which took off from Cape Canaveral Air Force Station in Florida, over the Atlantic Ocean, off the coast of central Florida.
