Magnificent CME Erupts on the Sun with Earth to Scale (por NASA Goddard Photo and Video)
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 at over 900 miles per second. The CME did not travel directly toward Earth, but did connect with Earth’s magnetic environment, or magnetosphere, causing aurora to appear on the night of Monday, September 3.
The image above includes an image of Earth to show the size of the CME compared to the size of Earth.

Desert RATS is a NASA team of engineers, geologists, astronauts, and technicians who go into the deserts of Arizona each summer to simulate missions to the Moon, Mars, and Near Earth Objects, which are small asteroids that are near Earth. This is the team that test drives the new Lunar Electric Rover and very futuristic space habitats.
This summer the women and men of Desert RATS are focusing on a mission to a Near Earth Object (NEO), so they are testing space suits, scientific procedures, and a space habitat that would orbit this NEO.
Their twitter handle is @DESERT_RATS and they are definitely a team to follow!

This rock, informally named “Tisdale 2,” was the first rock NASA’s Mars rover Opportunity examined in detail on the rim of Endeavour Crater. It has textures and composition unlike any rock the rover examined during its first 90 months on Mars. Its characteristics are consistent with the rock being a breccia — a type of rock fusing together broken fragments of older rocks.
I’m going to try something new on the Planetary Science Tumblelog today:
Space Missions take lots of pictures and they often take them close together. By overlapping two close images, we can make an anaglyph. Since Space is full of 3D stuff, we have lots to cover. Today PlanetSci will bring you two anaglyphs from Mars with NASA’s HiRISE Imager. So get out your red-cyan glasses!

Apollo 17 Landing Site, as seen from space!
NASA’s Lunar Reconnaissance Orbiter snapped pictures of the Apollo Landing Sites from low orbit. This picture and others were released on September 6th.
The parallel lines on the right? Moon Buggy tracks. The dark lines on the left? ASTRONAUT FOOTPRINTS! So clear!
Noah Petro, NASA lunar geophysicist, tells us that “we can retrace the astronauts’ steps with greater clarity to see where they took lunar samples.” Pretty awesome!

City lights illuminate this night time view of southern California, Mexico’s Baja California and the Gulf of Cortez, as photographed by one the Expedition 28 crew members onboard the International Space Station flying at altitude of approximately 220 miles. A 15-mm focal length was used to capture the time lapse image. The thin line of Earth’s atmosphere is visible above the horizon.
Astronauts get to see some pretty awesome views of the Earth when they are in outer space. From Titanic sinking icebergs in the Atlantic Ocean to the Mount Etna volcanic eruption in Sicily in 2002. Astronauts have been specially trained to observe the Earth and have snapped over 1,000,000 photos of our big blue planet from 175 missions to space. NASA has put all these Astronaut / part-time photographers photos online at The Gateway to Astronaut Photography of Earth.
What Kind of World Do You Want? (by ReelNASA)
Although STS-135 is the final space shuttle mission, the International Space Station will continue an uninterrupted human presence in space. This music video featuring the space station and its crews is set to the song “World” by recording artists Five for Fighting.
