“Today a new era in human spaceflight begins as we once again launched American astronauts on American rockets from American soil on their way to the International Space Station, our national lab orbiting Earth,” said NASA Administrator Jim Bridenstine. ![]() A SpaceX Falcon 9 rocket carrying the company’s Crew Dragon spacecraft is launched from Launch Complex 39A on NASA’s SpaceX Demo-2 mission to the International Space Station with NASA astronauts Robert Behnken and Douglas Hurley onboard, Saturday, May 30, 2020, at NASA’s Kennedy Space Center in Florida.

NASA’s Mars Exploration Rover Opportunity continues to make discoveries on MarsNASA Headquarters
The ground texture seen in recent images from the rover resembles a smudged version of very distinctive stone stripes on some mountain slopes on Earth that result from repeated cycles of freezing and thawing of wet soil. But it might also be due to wind, downhill transport, other processes or a combination. ![]() Textured rows on the ground in this portion of “Perseverance Valley” are under investigation by NASA’s Mars Exploration Rover Opportunity, which used its Navigation Camera to take the component images of this downhill-looking scene. The rover reaches its 5,000th Martian day, or sol, on Feb. 16, 2018. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Opportunity Rover cruises near rim of Endeavour CraterWritten by Laurie Cantillo / Dwayne Brown
Those scenarios are among the possible explanations rover-team scientists are considering for features seen just outside the crater rim’s crest above “Perseverance Valley,” which is carved into the inner slope of the rim. The team plans to drive Opportunity down Perseverance Valley after completing a “walkabout” survey of the area above it. ![]() The Pancam on NASA’s Mars Exploration Rover Opportunity took the component images of this enhanced-color scene during the mission’s “walkabout” survey of an area just above the top of “Perseverance Valley,” in preparation for driving down the valley.

Austin Peay State University professor Tamara Smithers publishes academic book on Italian Renaissance painter Michelangelo
“To speak candidly, I’ve been obsessed with Michelangelo – his artwork, his life and his legend – ever since I can remember,” Smithers said. «Read the rest of this article» Sections: Education | No Comments
NASA’s New Horizons spacecraft captures perlexing photo of Pluto’s landscapeNASA Headquarters
The image below — showing an area near the line that separates day from night — captures a vast rippling landscape of strange, aligned linear ridges that has astonished New Horizons team members. ![]() In this extended color image of Pluto taken by NASA’s New Horizons spacecraft, rounded and bizarrely textured mountains, informally named the Tartarus Dorsa, rise up along Pluto’s day-night terminator and show intricate but puzzling patterns of blue-gray ridges and reddish material in between. This view, roughly 330 miles (530 kilometers) across, combines blue, red and infrared images taken by the Ralph/Multispectral Visual Imaging Camera (MVIC) on July 14, 2015, and resolves details and colors on scales as small as 0.8 miles (1.3 kilometers).

NASA’s New Horizons spacecraft discovers Mountains, Ice Flows and Haze on PlutoWritten Dwayne Brown and Laurie Cantillo
“We knew that a mission to Pluto would bring some surprises, and now — 10 days after closest approach — we can say that our expectation has been more than surpassed,” said John Grunsfeld, NASA’s associate administrator for the Science Mission Directorate. “With flowing ices, exotic surface chemistry, mountain ranges, and vast haze, Pluto is showing a diversity of planetary geology that is truly thrilling.” ![]() Backlit by the sun, Pluto’s atmosphere rings its silhouette like a luminous halo in this image taken by NASA’s New Horizons spacecraft around midnight EDT on July 15. This global portrait of the atmosphere was captured when the spacecraft was about 1.25 million miles (2 million kilometers) from Pluto and shows structures as small as 12 miles across. The image, delivered to Earth on July 23, is displayed with north at the top of the frame. (NASA/JHUAPL/SwRI) «Read the rest of this article» Sections: Technology | No Comments
NASA’s New Horizons spacecraft answers decade old question, What is the Size of Pluto?NASA Headquarters
Mission scientists have found Pluto to be 1,473 miles (2,370 kilometers) in diameter, somewhat larger than many prior estimates. Images acquired with the Long Range Reconnaissance Imager (LORRI) were used to make this determination. This result confirms what was already suspected: Pluto is larger than all other known solar system objects beyond the orbit of Neptune. ![]() A portrait from the final approach. Pluto and Charon display striking color and brightness contrast in this composite image from July 11, showing high-resolution black-and-white LORRI images colorized with Ralph data collected from the last rotation of Pluto. Color data being returned by the spacecraft now will update these images, bringing color contrast into sharper focus.
