Geocentric Map Of The Solar System.

Great detail of the famous crawler that transported the mighty Saturn V and all the space shuttles to the launch pads.  An engineering feat in its own right.

Io and Jupiter.

Description:  A four panel comic.  In the first two panels, me and my father are squinting at the night sky before I brighten and declare that ‘OH!  I see it!’  In the next panel is the night sky with two stars.  One bright one in the lower right center and a slightly dimmer one just above and to the left of the first one.  Text reads:  ‘This year, on December 21st, Jupiter and Saturn will line up, creating the ‘Christmas Star’ not seen for almost 400 years.  In the days leading up to it, you can see Jupiter shine brightly, with Saturn faintly shining just above it.’  In the final panel I am closing my window and looking up at the sky.  Captions read: ‘I keep looking up, finding and refinding it.’ And ‘The planets are always there, but this moment makes it all seem so fleeting.’

We will not leave the crew hanging!

The crew module uprighting system rotates Orion should it come to rest upside down when landing in the water.

Does an ecplispe cause any unusual effects on the Earth?

Yes, and this is one of the things we’re hoping to study more with this eclipse! If you are in totality, you’ll notice a significant temperature drop. We are also expecting to see changes in the Earth’s atmosphere and ionosphere. You can help us document these changes using the GLOBE Observer app https://www.globe.gov/globe-data/data-entry/globe-observer ! There are lots of great citizen science going on during this eclipse, and we’d love to have everyone here helping out! https://eclipse2017.nasa.gov/citizen-explorers

Just a reminder that the first NASA astronauts were supposed to be women because generally they are smaller, lighter (less weight in the cockpit means less fuel required) and eat less than men and so would be easier to accommodate in space. 

27 of Hubble's Best Photos for Its 27th Birthday

Hubble turns 27 today. Here's a look back at some of its most noteworthy accomplishments.

You may recognize the seventh picture in the slideshow--it’s my profile picture here. Happy birthday Hubble, you’re older than I am!

Hubble Spots Two Interacting Galaxies Defying Cosmic Convention

NASA - Hubble Space Telescope patch. March 24, 2017

Some galaxies are harder to classify than others. Here, Hubble’s trusty Wide Field Camera 3 (WFC3) has captured a striking view of two interacting galaxies located some 60 million light-years away in the constellation of Leo (The Lion). The more diffuse and patchy blue glow covering the right side of the frame is known as NGC 3447 — sometimes NGC 3447B for clarity, as the name NGC 3447 can apply to the overall duo. The smaller clump to the upper left is known as NGC 3447A. Overall, we know NGC 3447 comprises a couple of interacting galaxies, but we’re unsure what each looked like before they began to tear one another apart. The two sit so close that they are strongly influenced and distorted by the gravitational forces between them, causing the galaxies to twist themselves into the unusual and unique shapes seen here. NGC 3447A appears to display the remnants of a central bar structure and some disrupted spiral arms, both properties characteristic of certain spiral galaxies. Some identify NGC 3447B as a former spiral galaxy, while others categorize it as being an irregular galaxy.
