Apollo 11 Launches Humans to the Moon

Everybody saw the Moon. Nobody had ever been there. Humans across planet Earth watched in awe 50 years ago today as a powerful Saturn V rocket attempted to launch humans — to the Moon. Some in space flight guessed that the machinery was so complex, that so many things had to go right for it to work, that Apollo 11 would end up being another useful dress rehearsal for a later successful Moon-landing mission. But to the Moon they went. The featured video starts by showing astronauts Aldrin, Armstrong, and Collins making their way to the waiting rocket. As the Read more »

The Space Station Crosses a Spotless Sun

That’s no sunspot. It’s the International Space Station (ISS) caught passing in front of the Sun. Sunspots, individually, have a dark central umbra, a lighter surrounding penumbra, and no solar panels. By contrast, the ISS is a complex and multi-spired mechanism, one of the largest and most sophisticated machines ever created by humanity. Also, sunspots occur on the Sun, whereas the ISS orbits the Earth. Transiting the Sun is not very unusual for the ISS, which orbits the Earth about every 90 minutes, but getting one’s timing and equipment just right for a great image is rare. Strangely, besides that Read more »

Eagle Aurora over Norway

What’s that in the sky? An aurora. A large coronal mass ejection occurred on our Sun five days before this 2012 image was taken, throwing a cloud of fast moving electrons, protons, and ions toward the Earth. Although most of this cloud passed above the Earth, some of it impacted our Earth’s magnetosphere and resulted in spectacular auroras being seen at high northern latitudes. Featured here is a particularly photogenic auroral corona captured above Grotfjord, Norway. To some, this shimmering green glow of recombining atmospheric oxygen might appear as a large eagle, but feel free to share what it looks Read more »

NASA Funds Demo of 3D-Printed Spacecraft Parts Made, Assembled in Orbit

NASA has awarded a $73.7 million contract to Made In Space, Inc. of Mountain View, California, to demonstrate the ability of a small spacecraft, called Archinaut One, to manufacture and assemble spacecraft components in low-Earth orbit. The in-space robotic manufacturing and assembly technologies could be important for America’s Moon to Mars explor from NASA https://ift.tt/2YSKYzs via IFTTT

Hubble Peers at Galactic Cherry Blossoms

The galaxy NGC 1156 resembles a delicate cherry blossom tree flowering in springtime in this Hubble image. The many bright „blooms“ within the galaxy are in fact stellar nurseries — regions where new stars are springing to life. via NASA https://ift.tt/2JEsoof
