    (it seems like comet week). Explanation: Where do comet tails come from? There are no obvious places on the nuclei of comets from which the jets that create comet tails emanate. One of the best images of emerging jets is shown in the featured picture, taken in 2015 by ESA's robotic Rosetta spacecraft that orbited Comet 67P/Churyumov-Gerasimenko (Comet CG) from 2014 to 2016. The picture shows plumes of gas and dust escaping numerous places from Comet CG's nucleus as it neared the Sun and heated up. The comet has two prominent lobes, the larger one spanning about 4 kilometers, and...

    Explanation: Comet NEOWISE (C/2020 F3) is now sweeping through northern skies. Its developing tails stretch some six degrees across this telescopic field of view, recorded from Brno, Czech Republic before daybreak on July 10. Pushed out by the pressure of sunlight itself, the comet's broad, yellowish dust tail is easiest to see. But the image also captures a fainter, more bluish tail too, separate from the reflective comet dust. The fainter tail is an ion tail, formed as ions from the cometary coma are dragged outward by magnetic fields in the solar wind and fluoresce in the sunlight. In this...

    Explanation: Rounding the Sun on July 3rd and currently headed for the outer Solar System, Comet NEOWISE (C/2020 F3) has been growing brighter in the predawn skies of planet Earth. From low Earth orbit it also rises before the Sun, captured above the approaching glow along the eastern horizon in this snapshot from the International Space Station on July 5. Venus, now Earth's morning star is the brilliant celestial beacon on the right in the field of view. Above Venus you can spot the sister stars of the more compact Pleiades cluster. Earthbound skygazers can spot this comet with the...

    Explanation: These silvery blue waves washing over a tree-lined horizon in the eastern French Alps are noctilucent clouds. From high in planet Earth's mesosphere, they reflect sunlight in this predawn skyscape taken on July 8. This summer, the night-shining clouds are not new to the northern high-latitudes. Comet NEOWISE is though. Also known as C/2020 F3, the comet was discovered in March by the Earth-orbiting Near Earth Object Wide-field Infrared Survey Explorer (NEOWISE) satellite. It's now emerging in morning twilight only just visible to the unaided eye from a clear location above the northeastern horizon.

    NASA ^ | July 9, 2020
    NASA's Perseverance Mars rover has been attached to the top of the rocket that will send it toward the Red Planet this summer. Encased in the nose cone that will protect it during launch, the rover and the rest of the Mars 2020 spacecraft – the aeroshell, cruise stage, and descent stage – were affixed to a United Launch Alliance Atlas V booster on Tuesday, July 7, at Cape Canaveral Air Force Station in Central Florida. The process began when a 60-ton hoist on the roof of the Vertical Integration Facility at Space Launch Complex 41 lifted the nose cone,...

    The small communities were hiding in the overgrown landscape of the Middle East, but scientists say they hold vital clues to ancient civilisations that once inhabited this area. By combining spy-satellite photos obtained in the Sixties with modern satellite images and digital maps of Earth's surface, the researchers created a new method for mapping large-scale patterns of human movement. The approach, used to map sites spanning eight millennia across 23,000km of northeastern Syria, was published in the Proceedings of the National Academy of Sciences. Jason Ur, an archaeologist at Harvard University and study co-author, said in 2012: "Traditional archaeology goes...

    APOD.NASA ^ | 5 Jul, 2020 | NASA/Cassini Imaging Team
    Explanation: Why would clouds form a hexagon on Saturn? Nobody is sure. Originally discovered during the Voyager flybys of Saturn in the 1980s, nobody has ever seen anything like it anywhere else in the Solar System. Acquiring its first sunlit views of far northern Saturn in late 2012, the Cassini spacecraft's wide-angle camera recorded this stunning, false-color image of the ringed planet's north pole. The composite of near-infrared image data results in red hues for low clouds and green for high ones, giving the Saturnian cloudscape a vivid appearance. This and similar images show the stability of the hexagon even...

    NASA ^ | 06/24/2020
    As of June 2020, NASA’s Solar Dynamics Observatory – SDO – has now been watching the Sun non-stop for over a full decade. From its orbit in space around Earth, SDO has gathered 425 million high-resolution images of the Sun, amassing 20 million gigabytes of data over the past 10 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system. With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at...

    Lunar gravity is approximately one sixth of Earth’s gravity, so bodily fluids and the like will “fall down,” but more slowly, which brings its own icky challenges. There’s $35,000 in prize money up for grabs, plus the unending personal glory of being able to say you helped designed a moon toilet. There’s also a junior category for under-18s. There’s a fairly extensive list of technical requirements for the sought-after toilet, and creators will have to take into account a host of factors including female needs and sickness. For example, while the preferred method for capturing vomit will be emesis bags...
  • NASA Mars Helicopter Will Be Red Planet’s ‘Wright Brothers Moment’

    06/23/2020 11:26:09 AM PDT · by Red Badger · 42 replies ^ | June 23, 2020 | Staff
    NASA is about to take to the air on another planet. As part of its next mission to Mars, leaving Earth this summer, the space agency will attempt to do something that has never been done before: fly a helicopter through the rarefied atmosphere of Mars. If it works, the small helicopter, named Ingenuity, will open a new way for future robotic explorers to get a bird’s-eye view of Mars and other worlds in the solar system. “This is very analogous to the Wright brothers moment, but on another planet,” said MiMi Aung, the project manager of the Mars helicopter...
  • Quantum 'fifth state of matter' observed in space for first time

    Bose-Einstein condensates (BECs)—the existence of which was predicted by Albert Einstein and Indian mathematician Satyendra Nath Bose almost a century ago—are formed when atoms of certain elements are cooled to near absolute zero (0 Kelvin, minus 273.15 Celsius). At this point, the atoms become a single entity with quantum properties, wherein each particle also functions as a wave of matter. BECs straddle the line between the macroscopic world governed by forces such as gravity and the microscopic plane, ruled by quantum mechanics. Creating the fifth state of matter, especially within the physical confines of a space station, is no mean...
  • New SpaceX spacesuits get five-star rating from NASA astronauts

    The movie-star look to SpaceX's new spacesuits is just one of the innovative features the Crew Dragon astronauts enjoyed during the Demo-2 test flight to the International Space Station. NASA astronauts Doug Hurley and Bob Behnken were the first humans to wear the suits in space during their mission, which began May 30 with a flawless launch from Florida — the first human spaceflight from the region since the space shuttle program ended in 2011.
  • NASA spacecraft swoops down low over asteroid Bennu to eye sampling site

    The probe has been orbiting the asteroid since 2018 and has been preparing to collect a chunk of asteroid rock, which it will bring back to Earth in 2023. OSIRIS-REx is set to take the sample from the site named Nightingale on Oct. 20, 2020, but on May 26 the spacecraft took a dive toward Osprey, the backup sample collection site for the mission. OSIRIS-REx dropped down to just 820 feet (250 meters) above the site, which is the closest the spacecraft has been to Osprey. During the operation, the probe took 347 images from PolyCam, one of three cameras...

    Both NASA and China's space agency hope to launch new rovers for Mars in the coming weeks, and if they make it they'll become the 9th and 10th craft to successfully land on the surface of our planetary neighbor. Hopefully, neither NASA's Perseverance rover nor China's Tianwen-1 rover become the next machine to end its mission abruptly with a crash landing on Mars. At least two craft have crashed, while four others have lost contact with Earth just before or after landing. To mark the upcoming Martian launch season, which only occurs when the planets are best aligned for the...

    American ^ | June 1, 2020 | Steve Feinstein
    The SpaceX Demo-2/Dragon spacecraft was successfully launched into space on Saturday May 30, 2020, marking the first-ever collaboration between NASA and a private entity, Elon Musk's SpaceX. The Falcon 9 booster was comprised of nine SpaceX Merlin rocket engines, which use RP-1 (refined petroleum) and liquid oxygen as propellants to develop the immense thrust necessary for a heavy space-bound launch vehicle. All the news reports were dutifully filled with superlatives regarding this unprecedented public-private joint venture, and it was indeed a very significant accomplishment. It's not often that the two normally-opposing spheres of industry come together in such a positive...

    A day after arriving at the International Space Station on SpaceX’s Crew Dragon capsule, NASA astronauts Doug Hurley and Bob Behnken laid claim to a U.S. flag that symbolizes America’s capability to send people to orbit from U.S. soil. The handkerchief-sized flag, sealed in a plastic envelope, has been kept aboard the space station since 2011, when NASA’s final space shuttle crew left it behind before making their departure aboard Atlantis. It was displayed above the Harmony module’s hatch - and, for a time, stored in an equipment bag, nearly forgotten - with instructions that it was to be taken...

    How an unprecedented strategy cut costs, shook up the status quo, and returned the US to the forefront of space exploration. On Saturday afternoon, the Florida thunderstorms broke just long enough for history to be made. After 10 years of slow and sometimes painful change, NASA finally took the historic step of taking an astronaut into orbit in a private spacecraft. While discussion of this remarkable event has been overshadowed by riots and lockdowns occurring across the US, the importance of this launch cannot be understated. It shows the success of an unprecedented policy of privatization, with immense, positive consequences...
