Did you know that unfortunately no woman has ever visited the Moon?1

Let's see. They have played golf on the moon, road around in a car, and collected rocks.... I guess you're right.

Sorry if someone mentioned this already...
Cassini, a probe that's been studying Saturn and its moons since 2004, will finally end once it crashes, deliberately, into Saturn while transmitting data about the atmosphere and its rings this September. I've been reading about it for awhile and it's pretty interesting.

Jupiter's Clouds of Many Colors
NASA's Juno spacecraft was racing away from Jupiter following its seventh close pass of the planet when JunoCam snapped this image on May 19, 2017, from about 29,100 miles (46,900 kilometers) above the cloud tops.
The spacecraft was over 65.9 degrees south latitude, with a lovely view of the south polar region of the planet.
This image was processed to enhance color differences, showing the amazing variety in Jupiter's stormy atmosphere.
The result is a surreal world of vibrant color, clarity and contrast. Four of the white oval storms known as the "String of Pearls" are visible near the top of the image.
Interestingly, one orange-colored storm can be seen at the belt-zone boundary, while other storms are more of a cream color.1 -
Henderson Island, South Pacific
Uninhabited Henderson Island is part of the United Kingdom's Pitcairn Islands group in the South Pacific.
According to a study by the University of Tasmania published in the Proceedings of the National Academy of Science, the island has the highest density of plastic waste anywhere in the world, an estimated 38 million pieces of rubbish.
The island is near the center of an ocean current, so it collects rubbish from boats and South America.
The image was acquired February 7, 2012, covers an area of 10.3 by 12.3 km, and is located at 24.3 degrees south, 128.3 degrees west.2 -
The White Cliffs of "Rover"
This image from NASA's Mars Reconnaissance Orbiter is reminiscent of the rugged and open terrain of a stark shore-line, perhaps of an island nation, such as the British Isles.
A close-up in enhanced color produces a striking effect, giving the impression of a cloud-covered cliff edge with foamy waves crashing against it. The reality is that the surface of Mars is much dryer than our imaginations might want to suggest.
This is only a tiny part of a much larger structure; an inverted crater -- a crater that has been infilled by material that is more resistant to erosion than the rocks around it -- surrounded by bluish basaltic dunes. The edge of these elevated light-toned deposits are degraded, irregular and cliff-forming.
Dunes visible below the cliff, give the impression of an ocean surface, complete with foam capped waves crashing against the "shore line," demonstrating the abstract similarity between the nature of a turbulent ocean and a Martian dune field. Meridiani Planum has an overall smooth terrain, which starkly contrasts with the more common boulder- and crater-laden landscapes observed over much of the rest of Mars. This makes it relatively younger in character than many other areas of the planet.
Meridiani is one of the Mars Exploration Rover landing sites, and, is known for its layers and sediments. The orbital detection of hematite was one of the main reasons for sending Opportunity to this area. Salt-bearing rocks -- also called sulphates -- were observed in the very first image from Opportunity, so perhaps it's apt that this HiRISE image reminds us of the turmoil and rugged beauty of a cliff-face, a coastline, being worn down by a relentless sea.1 -
I often worry that the reason we haven't met the aliens is because the natural course is to invent a strong AI which destroys the creators and in turn runs out of energy before branching to the next energy node. That...we are behind a "Big Rift" that naturally washes out civilizations and their robotic descendants on a universal-wide basis.
That's why I love the optimistic space-movies.
***** MOVIE SPOILER "INTERSTELLAR" *****
"Let's travel across time and space to find Matt Damon and kill him"...
hahahahahaha.
That's so incredibly wrong but funny to me. I really like Matt Damon...he would get the joke. I kept hoping for them to unzip another bag on a different planet and for Ben Affleck to pop out.
Also...c'mon people. Look at this.
Let's go ahead and try out the planet which doesn't get it's light from a black hole first next time? Okie dokie? That has got to be some seriously bad Feng Shui.

Mars Rover Opportunity's View of 'Orion Crater' (Enhanced Color)
NASA's Opportunity Mars rover passed near this small, relatively fresh crater in April 2017, during the 45th anniversary of the Apollo 16 mission to the moon. The rover team chose to call it "Orion Crater," after the Apollo 16 lunar module.
The rover's Panoramic Camera (Pancam) recorded this view, presented in enhanced color to make differences in surface materials more easily visible. The crater's diameter is about 90 feet (27 meters). From the small amount of erosion or filling that Orion Crater has experienced, its age is estimated at no more than 10 million years. It lies on the western rim of Endeavour Crater.
For comparison, Endeavor is about 14 miles (22 kilometers) in diameter and more than 3.6 billion years old. This view combines multiple images taken through three different Pancam filters. The selected filters admit light centered on wavelengths of 753 nanometers (near-infrared), 535 nanometers (green) and 432 nanometers (violet).
The component images were taken on April 26, 2017, during the 4,712th Martian day, or sol, of Opportunity's work on Mars. Apollo 16 astronauts John Young and Charles Duke flew in the Orion lunar module to and from the first human landing in the lunar highlands while Ken Mattingly orbited the moon in the command module, Casper. On the moon, Young and Duke investigated Plum Crater, which is approximately the same size as Mars' Orion Crater.1 -

Those blue basaltic dunes look awesome ^0

NASA Galileo spacecraft took this image of Earth moon on December 7, 1992 on its way to explore the Jupiter system in 1995-97.
The distinct bright ray crater at the bottom of the image is the Tycho impact basin.

Twisting Plasma Interaction
Several short stalks of cooler, darker plasma spun and twisted as they interacted with each other at the sun's edge (June 14-15, 2017).
The row of strands, which together form a prominence, were being pulled back and forth by magnetic forces. The dynamic action was observed for just over one day.
Also noteworthy is the rapid development of a bright active region in the upper right about halfway through the clip.

This shows the relative distance of the earth from the sun and their comparable sizes.

All 4 earths even
