Sunrise, Sunset

SUNSET:  How many times have we all seen our sun sink below the horizon? 

Too many to count, if we're lucky.

We love this photo of our sun setting - on the Martian horizon!

It was recorded by NASA's Curiosity Mars rover on the mission's 956th Martian day, or sol (April 15, 2015), from the rover's location in Gale Crater.

Interestingly, it's the first sunset observed in color by Curiosity. It's from its left-eye camera on Mastcam. Per NASA, "The color has been calibrated and white-balanced to remove camera artifacts. Mastcam sees color very similarly to what human eyes see, although it is actually a little less sensitive to blue than people are."

In other words, it's not too far off from if we were actually standing there, boots on ground. Awesome.

"Dust in the Martian atmosphere has fine particles that permit blue light to penetrate the atmosphere more efficiently than longer-wavelength colors," according to the Jet Propulsion Laboratory press release. "That causes the blue colors in the mixed light coming from the sun to stay closer to sun's part of the sky, compared to the wider scattering of yellow and red colors. The effect is most pronounced near sunset, when light from the sun passes through a longer path in the atmosphere than it does at mid-day."

BURN, BABY, BURN: First thing we did this morning was check to see if the Russian spacecraft Progress had fallen back to Earth overnight. Turns out, it did. Fortunately, it made its reappearance over the Pacific Ocean and there are no reports of debris harming any thing or one. 

SQUASHED:  Our different-produce-of-the day was a couple of lovely Mexican squash. We used our AS SEEN ON TV! Veggetti to "spiralize" (circle cut) them up, and then they were boiled for a couple of minutes.  I drained them, melted a bit of butter over the hot 'noodles,' crumbled some cotija cheese over them, drizzled on some lime juice and garlic salt, a little black pepper and then we ate it all up like little piggies. Sorry, we don't even have any photos to share. :/

SHORT STUFF:  What is a dwarf planet? Thanks to this snazzy 60-second video from NASA, now we know more!
