NASA's Marshall Space Flight Center in Huntsville, Alabama is developing a trio of new additive and milling technology to create a 3D-printed rocket nozzle that is simpler in design than comparable ones, yet is able to withstand extreme temperatures and pressures. Made by a new process called Laser Wire Direct Closeout (LWDC), a prototype nozzle was fired successfully for more than 1,040 accu
NASA is ramping up for the Mars 2020 mission's July 2020 launch as the space agency begins the Assembly, Test, and Launch Operations (ATLO) phase of the project at the Spacecraft Assembly Facility High Bay 1 at the Jet Propulsion Laboratory (JPL) in Pasadena, California. This includes the final assembly and electrical integration of flight hardware into the spacecraft's rocket-powered "sky cr
A team of scientists has discovered a previously unknown massive "supercolony" of penguins in Antarctica by identifying dark guano stains in NASA satellite imagery. Following a visit to the site, the team used a specialized drone-assisted system to count the population, revealing a stunning 1.5 million Adélie Penguins...Continue Reading Undiscovered "supercolony" of penguins revealed using NA
NASA has released a somber view of Saturn's night side, created from some of the final images captured by the Cassini spacecraft. An annotated version of the release poignantly highlights the region of Saturn's cloud surface in which the beloved probe would meet its end, just a few hours after the images used to create the new mosaic were captured...Continue Reading Cassini captures its own g
The search for extraterrestrial life has shifted gears over the last five years or so, with the Kepler Space Telescope alone bringing thousands of potentially habitable Earth-sized planets into focus. Things are unlikely to slow down as NASA prepares to unleash a couple of powerful new exoplanet-hunting tools, starting with the Transiting Exoplanet Survey Satellite (TESS), which just landed a
NASA's Goddard Space Flight Center (GSFC) in Greenbelt, Maryland has confirmed that the satellite discovered on January 20 by an amateur astronomer is very likely the lost Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) space weather satellite. The space agency says that it will attempt to capture data from the orbiter and restart its instruments. ..Continue Reading NASA to attem
NASA sees folding wings as a key aeronautical technology for the aircraft of tomorrow, and to make it practical, the space agency is looking to a cutting edge, lightweight memory alloy. Developed for the Spanwise Adaptive Wing (SAW) project, the new alloy allows an aircraft's wing and control surfaces to change their shape in flight without heavy hydraulic systems...Continue Reading NASA turn
Parts of the Northern Hemisphere might be shivering through a bitterly cold winter right now, but global temperature averages still soared over the last year. NASA and the National Oceanic and Atmospheric Administration (NOAA) have both released reports stating that 2017 was one of the hottest years since records began in 1880. That continues a long-term trend of rapid warming that doesn't bo
With GPS it's harder than ever to get lost here on Earth, but deep space is a different story. Mind-boggling distances, three-dimensional travel and a lack of obvious landmarks all complicate spacecraft navigation. Pulsars have been proposed as a solution in the past, and now a NASA team has demonstrated the viability of the idea, with an experiment showing that a spacecraft can constantly an
The hole in the ozone layer was one of the most headline-hogging environmental issues of the 1980s and 90s, but an international ban on damaging chemicals have helped it recover in the 30 years since. It's long been known that the hole is shrinking, but a new study has measured the improving health of the ozone layer by analyzing the chemicals around the hole over the last decade or so...Cont is a social bookmarking place where you can share, find & discuss the best news around on most topics.
