Courtesy NASATo paraphrase Capt. Kirk, we've now gone boldly where no one has gone before. After 35 years and 11 billion miles of travel, NASA's Voyager I spacecraft has officially left our solar system. Measuring instruments on the craft no longer defect the movement of solar wind, which is the movement of particles influenced by energy released by our Sun, around Voyager I. Following not too far behind is Voyager II, which as covered about 9.5 billion miles. You can learn more about the milestone by clicking here.
UPDATE: Wait a second, NASA isn't agreeing with this analysis on Voyager I's location. You can read more about this brewing science controversy here. Does Pluto have anything to do with this?
The Mars rover, Curiosity, has made an historic drilling into rock on the surface of Mars. The feat is a first in planetary exploration.
"This is the biggest milestone accomplishment for the Curiosity team since the sky-crane landing last August, another proud day for America," said John Grotizinger, the mission's lead scientist.“
The next step is to have the extracted gray powdered rock analyzed by Curiosity's on-board laboratory to determine the sample's chemistry and mineralogy,

This week the Mars rover Opportunity is marking its tenth year of rolling around the Red Planet. Not too shabby for something that was designed for just a quick three-month life span. It's partner rover, Spirit, seized up and got permanently stuck in sand three years ago. And now both vehicles are being overshadowed by Curiosity, the high-tech rover that just landed on Mars five months ago.
Like any older vehicle, Opportunity has its quirks. It gets around mostly in reverse these days because one of the front wheels doesn't turn well. Its robot arm needs some extra coaxing from operators to get jobs done. But it's still collecting samples and data. It total, it's logged 22 miles across the Martian terrain. Not too shabby for a late model rover.
Here's a link to NASA's webpage of photos and information that Opportunity has collected over the years.
NASA scientists announced today that analysis of a soil sample scooped up by the Mars rover, Curiosity, and analyzed by its on-board lab shows evidence of organic compounds. However, whether the organics are indigenous to Mars or were brought by the rover to the Red Planet from Earth has not yet been determined, so NASA is keeping the excitement level subdued for the moment. The announcement was made today at a press conference at the American Geophysical Union meeting in San Francisco, California.

The SpaceX rocket lifted off today from a launch pad at Cape Canaveral, Florida, becoming the first commercial flight to the International Space Station and marking the beginning of a new era of space exploration. Read about it here.

My first impression looking at the image (which is comprised of several shots stitched together by graphic designer Ed Truthan) is that it looks like it's made up made up of cobbles, and pebbles and sand - the same kind of deposit you find here on Earth left by an old river channel.

Parker obviously must not have had much research work last April when the Hubble Telescope was celebrating its 22nd birthday, so he spent all the free time putting together this really cool recreation of the Van Gogh astronomical masterpiece using photo-mosaic software and several of Hubble’s stunning Top 100 images found here.
It's been, oh, maybe 3 weeks since I posted the last hi-def POV video of Curiosity's amazing descent to the surface of Mars but this time it's in Ultra High Def and at 30fps! Who wouldn't want to see that? And with audio no less. Not sure if the audio is dubbed in or was actually captured with the video. Compared to Earth Mars doesn't have much of an atmosphere but because sound can travel through several different types of media - air, liquids, solids, etc - audio capture would probably be possible but I'm not sure NASA set the rover up for that. Whatever the case, the imagery is worth seeing.
This truly stunning hi-def footage captured by NASA satellites positioned around our Sun, show various views of a coronal mass ejection that occurred August 31, 2012. Wow!!
FROM THE YOUTUBE SITE:
"On August 31, 2012 a long filament of solar material that had been hovering in the sun's atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled away from the sun at over 900 miles per second. This movie shows the ejection from a variety of viewpoints as captured by NASA's Solar Dynamics Observatory (SDO), NASA's Solar Terrestrial Relations Observatory (STEREO), and the joint ESA/NASA Solar Heliospheric Observatory (SOHO).“
A photograph captured by the Mars rover, Curiosity, shows an unconformity in the strata of Mount Sharp, a mountain inside nearby Gale Crater. An unconformity is a geological feature marking a stop in sedimentation and erosion of a surface before the overlying layer is deposited. The photo above shows the two distinct rock layers (marked by a line of white dots) that make up the unconformity. The upper layer, which is tilted left to right in relation to the lower layer, contains no evidence of hydrated minerals found in the lower layer. This idicates the two layers were laid down in different environments.
