International Space Station Managers Give Go for Tuesday Spacewalk

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – International Space Station Program managers have given the green light for a contingency spacewalk on Tuesday by two Expedition 51 crew members to change out a multiplexer-demultiplexer (MDM) data relay box on the S0 truss that failed on Saturday morning.

The cause of the MDM failure is not known. After a review of spacewalk preparations and crew readiness throughout the day Sunday, the decision was made to press ahead with the spacewalk on Tuesday. It will be conducted by Expedition 51 Commander Peggy Whitson and Flight Engineer Jack Fischer of NASA.

Fort Campbell KY - 101st Airborne DivisionFort Campbell, KY – When he was nominated for the GEICO Military Service Award, Sgt. 1st Class Julio Mella, 21st Brigade Engineer Battalion, 3rd Brigade Combat Team, 101st Airborne Division, was honored but did not think much about it.

“There were many, many people being nominated with me,” Mella said. “I wasn’t being pessimistic, just realistic.”

The GEICO Military Service Awards Program “spotlights the valuable and lasting contributions enlisted members of the armed forces make in three specific areas of endeavor,” according to the GEICO website.

Service members can be nominated for service in drug and alcohol abuse prevention, fire safety and fire prevention or traffic safety and accident prevention. Each year, one member from each branch of the service is selected to receive the award.

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’s Mars Rover Opportunity to study Perseverance Valley

 

Written by Guy Webster / Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Exploration Rover Opportunity has reached the main destination of its current two-year extended mission — an ancient fluid-carved valley incised on the inner slope of a vast crater’s rim.

As the rover approached the upper end of “Perseverance Valley” in early May, images from its cameras began showing parts of the area in greater resolution than what can be seen in images taken from orbit above Mars.

“The science team is really jazzed at starting to see this area up close and looking for clues to help us distinguish among multiple hypotheses about how the valley formed,” said Opportunity Project Scientist Matt Golombek of NASA’s Jet Propulsion Laboratory, Pasadena, California.

"Perseverance Valley" lies just on the other side of the dip in the crater rim visible in this view from the Navigation Camera (Navcam) on NASA's long-lived Mars Exploration Rover Opportunity, which arrived at this destination in early May 2017 in preparation for driving down the valley.

NASA begins planning for Orion Spacecraft manned mission

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – In February, NASA began an effort looking at the feasibility of putting crew aboard the first integrated flight of the Space Launch System rocket and Orion spacecraft — Exploration Mission-1, or EM-1. After weighing the data and assessing all implications, the agency will continue pursuing the original plan for the first launch, as a rigorous flight test of the integrated systems without crew. 

However, engineers will apply insights gained from the effort to the first flight test and the integrated systems to strengthen the long-term push to extend human presence deeper into the solar system.

New USDA Flexibility on School Meals is Really a Rollback says American Heart Association

 

American Heart AssociationWashington, D.C. American Heart Association CEO Nancy Brown issued the following comments regarding the USDA’s announcement on “regulatory flexibility” for the school meals program:

“The USDA’s less rigid stance on school nutrition standards is a rollback masquerading as ‘flexibility.’ 

In the last five years, nearly 100 percent of the nation’s schools have complied with updated school meal standards. Kids across the country have clearly benefited from these changes.

NASA and NOAA study shows warmer weather increasing Carbon Emissions from Alaska Tundra

 

Written by Ellen Gray
NASA Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Warmer temperatures and thawing soils may be driving an increase in emissions of carbon dioxide from Alaskan tundra to the atmosphere, particularly during the early winter, according to a new study supported by NASA and the National Oceanic and Atmospheric Administration (NOAA).

More carbon dioxide released to the atmosphere will accelerate climate warming, which, in turn, could lead to the release of even more carbon dioxide from these soils.

A new paper led by Roisin Commane, an atmospheric researcher at Harvard University in Cambridge, Massachusetts, finds the amount of carbon dioxide emitted from northern tundra areas between October and December each year has increased 70 percent since 1975.
