NASA Has Given The “Go” For A Highly Anticipated Mission To Europa

A mission to Europa is now under development after NASA gave the green light to a mission concept which would send a spacecraft to conduct flybys of Jupiter’s icy moon sometime in the 2020s to assess the world’s potential habitability. The mission concept passed its first major review by the agency, allowing the mission concept to enter the formulation stage of development.

Got any facts about 10-Dollar-Bill-Man, AKA Alexander Hamilton?

Alexander Hamilton is not on the 10 Dollar Bill. He’s supposed to be but on the day he was to sit for his portrait, he was needed at the capitol, so he sent a stand-in. There are conflicting reports as to who the stand in was.

Washington Irving reports that the stand-in was none other than Aaron Burr, who would go on to kill Alexander Hamilton in a duel over the ownership of a sheep named Bessie-May, who rumors of the time claimed was the lover of one man and the dinner of the other.

David Icke claimed that the stand-in was Adam Weishaupt, head of the Illuminati and true ruler of the nation. Weishaupt does indeed resemble the portrait, but historians consider his presence unlikely, as he was known to be in Germany at the time, devising a plan to end all religion and government.

Giorgio A. Tsoukalos finally claims that the stand-in was an alien named Lorp from a planet orbiting Sirius-B. According to Tsoukalos, Lorp was visiting Earth on a work visa from the Lord Regent of Betegeuse. Under this work visa, Lorp was to pose as Alexander Hamilton in order to influence the United States to eventually form a space program that would introduce them to the Galactic Übersenate of Omicron Persei 8. This plan was finally foiled by Zarkon L. Morzgarg, who assassinated the president while posing in the form of a grassy knoll, which is more or less what Zarkonians look like anyway.

Here is President Zarkon H. Needlebrain of the Zarkonian Congress:

So as you see, a Zarkonian could easily have posed as a grassy knoll, and I am absolutely not to blame for stepping on Zarkon C. Jessup on her visit to Earth because I mean look at them, they look like grassy hills, and I’ll be damned if I get blamed for starting an interstellar war for walking on one near the saucer.

And that’s all you need to know about Alexander Hamilton.

On July 4, 1997, the Mars Pathfinder rover, Sojourner, landed on the Red Planet.

Named for abolitionist and women’s rights activist Sojourner Truth, NASA’s Sojourner rover landed on Mars on July 4, 1997. Unlike previous landing systems that used conventional rockets to decelerate, the Sojourner rover used a parachute and a system of airbags to slow down before the rover dropped roughly 100 feet to the planet’s surface. This system comprised of the Pathfinder lander, which was renamed the Carl Sagan Memorial Station after successfully delivering the rover. Sagan, a major proponent of the exploration of Mars, passed away shortly after the Mars Pathfinder mission launched on its way to the Red Planet.

Sojourner then set about its mission to analyze nearby rocks on the surface. Compositional analysis revealed that silica was found in higher concentrations in rocks than the surrounding area. Being found in igneous rocks, such a presence of silica was a hint that Mars may have had a more interesting geological history than was previously thought. Sojourner also sent pictures of the Martian surface back to NASA, while Pathfinder took photographs of the Martian sky. Among the photos from Sojourner were images showing rounded pebbles and conglomerate rocks indicating that different types of soil had been mixed in the past—evidence of a formerly water-rich planet.

Originally scheduled to operate for 7 sols (1 sol is about 40 minutes longer than a day on Earth), Sojourner had the possibility of extending its mission to 30 sols. In total, Sojourner operated for 83 sols before communications were lost on September 27, 1997. In that time, it covered just over 100 meters of the Martian surface.

Voyager 1 is a NASA/JPL probe launched on September 5, 1977. Impressively enough, Voyager 1 is still sending us data, though its cameras were shut down long ago to conserve juice. Scientists never expected Voyager to be such a champ in that aspect, though they anticipate it will be out of fuel soon, likely around 2025. On August 25, 2012, it entered the official realm of interstellar space, something humans have never accomplished before. June of 2012 is when scientists realized that voyager had finally reached the heliopause, the point in space where the sun’s winds stop against the “interstellar medium”.

Above are some images captured by this incredible machine as it reached the outer planets.

Aurora Australis

Not fireworks, these intense shimmering lights still danced across Earth’s night skies late last month, seen here above the planet’s geographic south pole. The stunning auroral displays were triggered as a coronal mass ejection blasted from the Sun days earlier impacted the magnetosphere, beginning a widespread geomagnetic storm. The six fisheye panels were recorded with digital camera and battery in a heated box to guard against -90 degree F ambient temperatures of the long winter night. Around the horizon are south pole astronomical observatories, while beyond the Aurora Australis stretch the stars of the southern Milky Way.
