Air & Space Magazine 15 Nov 2018, 20:25 UTC A hot debate about how best to advance Mars exploration has been going on this week in the cold northern town of Lulea, Sweden. Scientists from many international space agencies and research organizations attended, including NASA, ESA, the Chinese and Japanese space agencies, and even the United Arab Emirates, which plans its own Martian mission for 2021.
Universe Today 15 Nov 2018, 16:27 UTC How in the world could you possibly look inside a star? You could break out the scalpels and other tools of the surgical trade, but good luck getting within a few million kilometers of the surface before your skin melts off. The stars of our universe hide their secrets very well, but astronomers can outmatch their cleverness and have found ways to peer into their hearts using, of all things, sound waves.
astrobites 15 Nov 2018, 07:35 UTC Imagine if we could watch planetary systems take shape. We would point our telescopes at the nearest and brightest newly-formed stars that are still surrounded by some of the leftover material from the cloud in which they formed. We would then see this leftover material mold itself into a disk around the star, a so-called “proto-planetary disk” made up of mostly gaseous molecules and a small, but sufficient amount of dust for building planets. Every day, we could observe each disk and watch each system evolve.
Astro Bob 14 Nov 2018, 23:21 UTC There are 190 confirmed impact structures on the Earth. Er, make that 191. An international team of researchers, including a NASA glaciologist, has discovered a new crater hiding beneath more than a half-mile of ice in northwest Greenland. The crater — the first of any size found under the Greenland ice sheet — is one of the 25 largest impact craters on Earth, measuring roughly 1,000 feet (305 meters) deep and more than 19 miles (31 km) in diameter.
Universe Today 14 Nov 2018, 21:54 UTC Ever since the Pioneer and Voyager probes passed through the Jovian system in the 1970s, NASA and other space agencies have dreamed of one-day sending a mission to Europa. Beyond Earth, it is considered one of the most promising candidates for finding life, which could exist in the subsurface ocean that lies beneath the moon’s icy crust. One of these concepts is known as the Cool High Impact Method for Exploring Down into Europan Subsurface (ARCHIMEDES), a proposed direct-laser penetrator that will use a laser light carried by an optical fiber tether to penetrate Europa’s icy crust. This mission could provide future missions with access to the ocean that exists beneath Europa’s surface and enable the search for life there.
NASA Space Station Blog 14 Nov 2018, 17:33 UTC Dismal weather on Virginia’s Atlantic coast has pushed back the launch of a U.S. cargo craft to the International Space Station one day to Friday. Russia’s resupply ship is still on track for its launch to the orbital lab from Kazakhstan less than nine hours later on the same day.
Astrobiology Magazine 14 Nov 2018, 15:33 UTC The Atacama Desert, the driest and oldest desert on Earth, located in northern Chile, hides a hyper-arid core in which no rain has been recorded during the past 500 years. But this situation has changed in the last three years.
Astronomy Now 14 Nov 2018, 14:23 UTC NASA’s Juno spacecraft carried out its 16th close flyby of Jupiter on 29 October, sailing just 7,000 kilometres (4,400 miles) above the giant planet’s turbulent atmosphere. This Junocam image was processed by citizen scientists Seán Doran and Gerald Eichstädt, showing bright white “pop-up” clouds and a huge white anticyclonic storm in Jupiter’s North North Temperate Belt. The image is centred on a latitude of about 40 degrees north latitude. Junocam is a public outreach camera and its images are available on line for processing by interested citizen scientists.
