NASA, SpaceX have successful Final Test Flight of Crew Dragon Spacecraft

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – On Sunday, January 19th, 2020 NASA and SpaceX completed a launch escape demonstration of the company’s Crew Dragon spacecraft and Falcon 9 rocket. This was the final major flight test of the spacecraft before it begins carrying astronauts to the International Space Station under NASA’s Commercial Crew Program.

The launch escape test began at 9:30am CT with liftoff from historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida on a mission to show the spacecraft’s capability to safely separate from the rocket in the unlikely event of an inflight emergency.

SpaceX, NASA to launch final, major In-Flight Abort Demonstration before Astronauts board Crew Dragon Spacecraft

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA and SpaceX postponed the test until Sunday, January 19th, due to sustained winds and rough seas in the recovery area. Further updates will be available from NASA’s commercial crew blog.

NASA and SpaceX are preparing to launch the final, major test before astronauts fly aboard the Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program.

The uncrewed in-flight abort demonstration is targeted for 7:00am CT Sunday, January 19th, from Launch Complex 39A in Florida. There is a four-hour test window. (SpaceX)

NASA reports Seals used to study how heat moves through Ocean Layers

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA says the Antarctic Circumpolar Current flows in a loop around Antarctica, connecting the Atlantic Ocean, Pacific Ocean and Indian Ocean. It is one of the most significant ocean currents in our climate system because it facilitates the exchange of heat and other properties among the oceans it links.

But how the current transfers heat, particularly vertically from the top layer of the ocean to the bottom layers and vice versa, is still not fully understood. This current is very turbulent, producing eddies – swirling vortices of water similar to storms in the atmosphere – between 30 to 125 miles (50 to 200 kilometers) in diameter.

NASA’s Geosynchronous Littoral Imaging and Monitoring Radiometer (GLIMR) instrument to observe Coastal Ecosystems

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA has selected a space-based instrument under its Earth Venture Instrument (EVI) portfolio that will make observations of coastal waters to help protect ecosystem sustainability, improve resource management, and enhance economic activity.

The selected Geosynchronous Littoral Imaging and Monitoring Radiometer (GLIMR) instrument, led by principal investigator Joseph Salisbury at the University of New Hampshire, Durham, will provide unique observations of ocean biology, chemistry, and ecology in the Gulf of Mexico, portions of the southeastern United States coastline, and the Amazon River plume – where the waters of the Amazon River enter the Atlantic Ocean.

NASA's Geosynchronous Littoral Imaging and Monitoring Radiometer (GLIMR) instrument will collect high-resolution observations of coastal ecosystems in such areas as the northern Gulf of Mexico, shown in this image with phytoplankton blooms stretching from the Texas and Louisiana coast (left) across the Mississippi River delta (center) toward Florida (far right).

NASA successfully tests Orion Spacecraft’s Launch Abort System

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – On Tuesday, July 2nd, 2019, NASA had a successful demonstration of how the Orion spacecraft’s launch abort system can outrun a speeding rocket and pull astronauts to safety during an emergency during launch. The test is another milestone in the agency’s preparation for Artemis missions to the Moon that will lead to astronaut missions to Mars.

During the approximately three-minute test, called Ascent Abort-2, a test version of the Orion crew module launched at 6:00am CDT from Space Launch Complex 46 at Cape Canaveral Air Force Station in Florida on a modified Peacekeeper missile procured through the U.S. Air Force and built by Northrop Grumman.

NASA Extreme Environment Mission Operations to prepare Astronauts for Space Missions

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Beginning June 10th, NASA will future deep space missions by joining an international crew on the floor of the Atlantic Ocean this summer during the 10-day NASA Extreme Environment Mission Operations (NEEMO) 23 expedition.

NEEMO 23 will focus on both exploration spacewalks and objectives related to space missions such as the International Space Station and future deep space missions to the Moon and Mars. As an analogue for future planetary science concepts and strategies, marine science also will be performed under the guidance of Florida International University’s marine science department.

NASA excited about Apophis Asteroid passing by Earth in 2029

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA says that a speck of light will streak across the sky, getting brighter and faster on April 13th, 2029. At one point it will travel more than the width of the full Moon within a minute and it will get as bright as the stars in the Little Dipper.

But it won’t be a satellite or an airplane – it will be a 1,100-foot-wide (340-meter-wide) near-Earth asteroid called 99942 Apophis that will cruise harmlessly by Earth, about 19,000 miles (31,000 kilometers) above the surface. That’s within the distance that some of our spacecraft that orbit Earth.

The international asteroid research community couldn’t be more excited.

This illustration shows the distance between the Apophis asteroid and Earth at the time of the asteroid's closest approach. The blue dots are the many man-made satellites that orbit our planet, and the pink represents the International Space Station. (NASA/JPL-Caltech)

NASA says Greenland’s fastest moving, fastest thinning Glacier is slowing, thickening

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA research shows that Jakobshavn Glacier, which has been Greenland’s fastest-flowing and fastest-thinning glacier for the last 20 years, has made an unexpected about-face.

Jakobshavn is now flowing more slowly, thickening, and advancing toward the ocean instead of retreating farther inland. The glacier is still adding to global sea level rise – it continues to lose more ice to the ocean than it gains from snow accumulation – but at a slower rate.
