Explanation: This Rosetta spacecraft selfie was snapped on October 7th, 2014. At the time the comet-chasing spacecraft was about 472 million kilometers from planet Earth, but only 16 kilometers from the surface of comet 67P/Churyumov-Gerasimenko. Looming beyond the spacecraft near the top of the frame, dust and gas stream away from the comet’s curious double-lobed
Since elementary school, we’ve all been taught the “5-Second Rule.” The idea is simple: Food dropped on the floor is still perfectly edible if retrieved in under five seconds. The logic behind the theory, such as it is, is that germs and dirt and pet dander are somehow caught by surprise by the sudden arrival
NASA’s Neil Gehrels Swift Observatory has ended its science mission now that the spacecraft is orbiting less than 171 miles (275 kilometers) above Earth’s surface. The greater atmospheric drag at this height prevents the satellite’s telescopes from steadily gazing at their astronomical targets. Swift conducted its final observation on Oct. 20. It is expected to
Before astronauts return to the lunar surface, NASA will first conduct one of the most ambitious and complex test missions in the agency’s history. Launching in 2027, Artemis III will send NASA astronauts Randy Bresnik, Frank Rubio, Andre Douglas, and ESA (European Space Agency) astronaut Luca Parmitano aboard the Orion spacecraft into low Earth orbit
As NASA returns humans to the lunar surface and establishes a long-term presence on our closest celestial neighbor, the agency and commercial human landing system providers Blue Origin and SpaceX have streamlined the designs and changed both concepts of operations for its future crewed landers. Since NASA established initial contracts with Blue Origin and SpaceX
For 13 years, photographer Imre Potyó has ventured into restricted-access mine tunnels in the Börzsöny Mountains of Hungary to capture images of hibernating lesser horseshoe bat (Rhinolophus hipposideros). Despite their deep slumber, the bats occasionally wake to hunt insects that enter the dark caves. “In doing so, the bat leaves behind droppings that gradually accumulate
