SpaceX, the private rocket company of high-tech entrepreneur Elon Musk, launched the first batch of 60 small satellites into low-Earth orbit on Thursday for Musk’s new Starlink internet service.
Newly discovered layers of ice buried a mile beneath Mars’ north pole are the remnants of ancient polar ice sheets and could be one of the largest water reservoirs on the planet, according to scientists at The University of Texas at Austin and the University of Arizona.
NASA hasn’t launched living creatures to deep space (on purpose) since 1972.
About a billion miles more distant than Pluto is Ultima Thule, a peanut-shaped object in the outer solar system that’s the farthest place ever visited by humans.
The Moon is shrinking as its interior cools, getting more than about 150 feet (50 meters) skinnier over the last several hundred million years. Just as a grape wrinkles as it shrinks down to a raisin, the Moon gets wrinkles as it shrinks. Unlike the flexible skin on a grape, the Moon’s surface crust is brittle, so it breaks as the Moon shrinks, forming “thrust faults” where one section of crust is pushed up over a neighboring part.
In the Chinese science fiction film The Wandering Earth, recently released on Netflix, humanity attempts to change the Earth’s orbit using enormous thrusters in order to escape the expanding sun – and prevent a collision with Jupiter.
In 2020, NASA and European-Russian missions will look for evidence of past life on Mars. But while volcanic, igneous rock predominates on the Red Planet, virtually the entire Earth fossil record comes from sedimentary rocks.
A Curtin University researcher has solved a nearly 100-year-old riddle by discovering that glass found in the Egyptian desert was created by a meteorite impact, rather than atmospheric airburst, in findings that have implications for understanding the threat posed by asteroids.
