3D printing has moved from a hobbyist’s best friend to one of the most useful tools in nearly every industry. With a computer and a bit of heat, you can turn strings of plastic filament into nearly anything. More advanced … Continue reading
On a clear night, we can look up at the night sky and see our galaxy – The Milky Way – spinning away in the blackness. Even with the naked eye, it’s a magnificent sight to behold, but we can’t … Continue reading
If you’re lucky when you look up in the sky at night, you might see a shooting star. As you’re making your wish, what you’re actually seeing is a small piece of rock or space junk burning up in the … Continue reading
Jupiter is named after the king of the Roman gods, and with its massive size, it definitely holds the title of king of the Solar System. NASA’s Juno spacecraft entered orbit around the gas giant in July of 2016. Due … Continue reading
Water really is everywhere. Two teams of astronomers, each led by scientists at the California Institute of Technology (Caltech), have discovered the largest and farthest reservoir of water ever detected in the universe. Continue reading
This photo of Vesta was taken by the Dawn spacecraft from the asteroid’s orbit on July 17. Vesta is a large asteroid with a mean diameter of about 530 kilometers. It is the second most massive object in the asteroid belt after Ceres and consists of about 9% of all the belt’s mass. Continue reading
Europe’s ambition for a spacecraft to return autonomously from low orbit is a cornerstone for a wide range of space applications, including space transportation, exploration and robotic servicing of space infrastructure. Continue reading
Sample return is something of a holy grail to planetary explorers. The advantage is that age dating and extensive compositional analysis can be done better with modern instruments in Earth-based laboratories than on miniaturized instruments that have to prepared years in advance for space flight. Continue reading
About one in 10 rocky planets around stars like our Sun may host a moon proportionally as large as Earth’s, researchers say. Our Moon is disproportionately large – more than a quarter of Earth’s diameter – a situation once thought to be rare. Continue reading
Having finished writing about the space elevator, I am moving on to another spacelaunch method in this new article in the non-rocket spacelaunch series. Tether propulsion consists in using long, very strong cables (known as tethers) to change the velocity … Continue reading
