NASA Goddard Technologists and Scientists Prepare for a New Era of Human Exploration

 

Written by Lori Keesey

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA scientists, engineers, and technologists are preparing for a new era of human exploration at the Moon, which includes a new launch system, capsule, and lunar-orbiting outpost that will serve as the jumping-off point for human spaceflight deeper into the Solar System.

NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is playing a vital role in these initiatives, particularly in the areas of communications and instrument development as evidenced by the recent award of five proposals under NASA’s Development and Advancement of Lunar Instrumentation (DALI) to advance spacecraft-based instrument for use in lunar-landing missions.

The technologies needed for sustainable exploration at the Moon will have to be powerful, multipurpose, and fast, said Jake Bleacher, Chief Scientist for the Human Exploration and Operations Mission Directorate.

NASA to Study Space Weather around Earth from International Space Station

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA has selected a new mission that will help scientists understand and, ultimately, forecast the vast space weather system around our planet. Space weather is important  because it can have profound impacts – affecting technology and astronauts in space, disrupting radio communications and, at its most severe, overwhelming power grids.

The new experiment will, for the first time, obtain global observations of an important driver of space weather in a dynamic region of Earth’s upper atmosphere that can cause interference with radio and GPS communications.

An image taken from the International Space Station shows orange swaths of airglow hovering in Earth’s atmosphere. NASA’s new Atmospheric Waves Experiment will observe this airglow from a perch on the space station to help scientists understand, and ultimately improve forecasts of, space weather changes in the upper atmosphere.

NASA uncovers evidence that Southern California fault connects to fault in Mexico

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A multiyear study has uncovered evidence that a 21-mile-long (34-kilometer-long) section of a fault links known, longer faults in southern California and northern Mexico into a much longer continuous system. The entire system is at least 217 miles (350 kilometers) long.

Knowing how faults are connected helps scientists understand how stress transfers between faults. Ultimately, this helps researchers understand whether an earthquake on one section of a fault would rupture multiple fault sections, resulting in a much larger earthquake.

NASA’s GRACE-FO Satellite to Switch to Backup Instrument Processing Unit

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission team plans to switch to a backup system in the Microwave Instrument (MWI) on one of the twin spacecraft this month. Following the switch-over, GRACE-FO is expected to quickly resume science data collection.

A month after launching this past May, GRACE-FO produced its first preliminary gravity field map. The mission has not acquired science data since mid-July due to an anomaly with a component of the Microwave Instrument on one of the GRACE-FO spacecraft. The mission team is completing its investigation into the cause of the anomaly.

Tennessee Department of Agriculture says more and more Farmers Markets accept SNAP

 

Tennessee Department of Agriculture

Tennessee Department of AgricultureNashville, TN – Tennessee Department of Agriculture says in Tennessee, a growing number of farmers markets are putting more dollars into farmers’ pockets while helping hungry people maximize their access to fresh food.

Forty of Tennessee’s farmers markets now work with the Supplemental Nutrition Assistance Program (SNAP), the federal government’s primary anti-hunger program.

Buying Farm fresh foods is a “Snap” at Tennessee Farmers Markets.

NASA’s Parker Solar Probe launches tonight

 

Written by Miles Hatfield
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – At 2:33am CDT on August 11th, 2018 while most of the U.S. is asleep, NASA’s Kennedy Space Center in Florida will be abuzz with excitement. At that moment, NASA’s Parker Solar Probe, the agency’s historic mission to touch the Sun, will have its first opportunity to lift off.

Launching from Cape Canaveral Air Force Station in Florida, Parker Solar Probe will make its journey all the way to the Sun’s atmosphere, or corona — closer to the Sun than any spacecraft in history.

“Eight long years of hard work by countless engineers and scientists is finally paying off,” said Adam Szabo, the mission scientist for Parker Solar Probe at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
