The 15th Anniversary of New Horizons Leaving Earth
Wednesday, 20 January 2021 09:26New Horizons is healthy and continues to send data back from the Kuiper Belt, even as it speeds farther and farther from the Earth and the Sun. But the mission's jam-packed plans for new Kuiper Belt exploration this year are not the subject of this PI Perspective. Instead, I want to concentrate on a very special anniversary, taking place today - our 15th anniversary of launch! That's
Astronomers estimate Titan's largest sea is 1,000 feet deep
Wednesday, 20 January 2021 09:26Far below the gaseous atmospheric shroud on Saturn's largest moon, Titan, lies Kraken Mare, a sea of liquid methane. Cornell astronomers have estimated that sea to be at least 1,000 feet deep near its center - enough room for a potential robotic submarine to explore. After sifting through data from one of the final Titan flybys of the Cassini mission, the researchers detailed their finding
Crater study offers window on temperatures 3.5 billion years ago
Wednesday, 20 January 2021 09:26Once upon a time, seasons in Gale Crater probably felt something like those in Iceland. But nobody was there to bundle up more than 3 billion years ago. The ancient Martian crater is the focus of a study by Rice University scientists comparing data from the Curiosity rover to places on Earth where similar geologic formations have experienced weathering in different climates. Iceland'
SpaceX launches first Starlink satellite mission of 2021
Wednesday, 20 January 2021 09:26SpaceX launched another shipment of 60 Starlink satellites from Florida on Wednesday morning, adding to a rapidly growing cluster of high-speed broadband communications spacecraft. The Falcon 9 rocket lifted off as planned at 8:02 a.m. EST into a cool, blue winter sky from Complex 39 at Kennedy Space Center. The satellites deployed into their intended orbit one hour and four minutes aft
Search for axions from nearby star Betelgeuse comes up empty
Wednesday, 20 January 2021 09:26The elusive axion particle is many times lighter than an electron, with properties that barely make an impression on ordinary matter. As such, the ghost-like particle is a leading contender as a component of dark matter - a hypothetical, invisible type of matter that is thought to make up 85 percent of the mass in the universe. Axions have so far evaded detection. Physicists predict that i
Astroscale's ELSA-d debris buster ready for a March launch
Wednesday, 20 January 2021 09:26Astroscale reports that its End-of-Life Services by Astroscale-demonstration (ELSA-d) satellite has arrived at the Baikonur Cosmodrome in Kazakhstan, ready for anticipated launch on March 20, 2021. ELSA-d will launch on a Soyuz rocket operated by GK Launch Services. "We can now begin the final phase of pre-launch activities, including integration of the satellite on the rocket and operatio
Lunar Surface Trash or Treasure?
Wednesday, 20 January 2021 09:26Now that NASA is leading the development of the Artemis lunar habitation program that will send men and women to the Moon within the next few years, this may be a good time to preview at least one aspect of the environment that the astronauts will experience when they arrive, i. e., trash from Earth. Since 1959, the lunar surface has experienced a barrage of man-made attacks of various kin
Autonomous driving on intelligent road at Europe's edge
Wednesday, 20 January 2021 09:26An ESA-supported effort put an intelligent road up in Finnish Lapland through its paces, assessing its suitability for testing autonomous vehicles in some of Europe's most challenging driving conditions. "If autonomous vehicles can drive well here, they can drive almost anywhere," says Sarang Thombre of the Finnish Geospatial Research Institute, managing the Arctic-PNT project. "Our
Astronomers dissect the anatomy of planetary nebulae using Hubble images
Wednesday, 20 January 2021 09:26Images of two iconic planetary nebulae taken by the Hubble Space Telescope are revealing new information about how they develop their dramatic features. Researchers from Rochester Institute of Technology and Green Bank Observatory presented new findings about the Butterfly Nebula (NGC 6302) and the Jewel Bug Nebula (NGC 7027) at the 237th meeting of the American Astronomical Society on Friday, J
Lake heatwaves to increase due to climate change
Wednesday, 20 January 2021 08:00Lake heatwaves – periods of extreme warm surface water temperature in lakes – may become hotter and longer by the end of the 21st century, according to a new study published in Nature, increasing the link between climate change and extreme events.
