NASA’s Mars Curiosity Rover has now spent 2,000 Martian Days on Mars

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Curiosity rover just hit a new milestone: its two-thousandth Martian day, or sol, on the Red Planet. An image mosaic taken by the rover in January offers a preview of what comes next.

Looming over the image is Mount Sharp, the mound Curiosity has been climbing since September 2014. In the center of the image is the rover’s next big, scientific target: an area scientists have studied from orbit and have determined contains clay minerals.

This mosaic taken by NASA's Mars Curiosity rover looks uphill at Mount Sharp, which Curiosity has been climbing since 2014. Highlighted in white is an area with clay-bearing rocks that scientists are eager to explore; it could shed additional light on the role of water in creating Mount Sharp. The mosaic was assembled from dozens of images taken by Curiosity's Mast Camera (Mastcam). It was taken on Sol 1931 back in January. (NASA/JPL-Caltech/MSSS)

NASA’s Mars Exploration Rover Opportunity continues to make discoveries on Mars

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Mars Exploration Rover Opportunity keeps providing surprises about the Red Planet, most recently with observations of possible “rock stripes.”

The ground texture seen in recent images from the rover resembles a smudged version of very distinctive stone stripes on some mountain slopes on Earth that result from repeated cycles of freezing and thawing of wet soil. But it might also be due to wind, downhill transport, other processes or a combination.

Textured rows on the ground in this portion of "Perseverance Valley" are under investigation by NASA's Mars Exploration Rover Opportunity, which used its Navigation Camera to take the component images of this downhill-looking scene. The rover reaches its 5,000th Martian day, or sol, on Feb. 16, 2018. (NASA/JPL-Caltech)

Letter to Editor Update for Land Between the Lakes

 

Land Between the Lakes - LBLDear Editor,

As many know, Land Between the Lakes has experienced widespread wind and water damage.

It has been confirmed that the same storm that traveled through Marshall County on Wednesday, July 6th also crossed Land Between the Lakes.

It contained a tornado which touched down near Cravens Bay Campground, traveling along the ground for approximately a quarter mile before it went across Lake Barkley into Trigg County. The high winds impacted trees, open lands and other resources along its path.

NASA reports Space Telescopes reveal fierce winds coming from Black Hole

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and ESA’s (European Space Agency) XMM-Newton telescope are showing that fierce winds from a supermassive black hole blow outward in all directions — a phenomenon that had been suspected, but difficult to prove until now.

This discovery has given astronomers their first opportunity to measure the strength of these ultra-fast winds and prove they are powerful enough to inhibit the host galaxy’s ability to make new stars.

NASA looks into the Mystery of the Missing Waves on the Lakes of Saturn’s moon Titan

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – One of the most shocking discoveries of the past 10 years is how much the landscape of Saturn’s moon Titan resembles Earth.

Like our own blue planet, the surface of Titan is dotted with lakes and seas; it has river channels, islands, mud, rain clouds and maybe even rainbows. The giant moon is undeniably wet.

The “water” on Titan is not, however, H2O. With a surface temperature dipping 290 degrees fahrenheit below zero, Titan is far too cold for liquid water. Instead, researchers believe the fluid that sculpts Titan is an unknown mixture of methane, ethane, and other hard-to-freeze hydrocarbons.
