Mars rover Curiosity's shadow in Gale Crater  (Source: NASA Twitter)
The $2.5 billion project was made in hopes of discovering that the Red Planet once harbored materials needed for life

NASA celebrated a major victory early Monday morning as its Mars rover Curiosity made a successful landing on the Red Planet. 
NASA rover Curiosity is a one-ton, nuclear-powered, six-wheeled, Mini Cooper-sized machine that was originally called the Mars Science Laboratory -- because that's exactly what it is. It was made to explore Martian territory for a two-year period in hopes of discovering that the planet once harbored materials needed for life. The project cost $2.5 billion.
Curiosity launched from Cape Canaveral, Florida on November 26, 2011. It has made its way through space for eight months before touching down on Mars. It covered about 352 million miles during that eight-month period.
This morning's landing was not an easy one. Many doubted that NASA could pull off such a stunt because the actual maneuver consisted of a giant parachute and a rocket pack lowering the huge laboratory onto a specific area, and errors were not allowed if NASA engineers wanted Curiosity to stay intact. Also, about 70 percent of missions to Mars have ended in failure, so landing the largest vehicle on the planet seemed impossible.
"It's like us launching something from Kennedy Space Center and having it land in the Rose Bowl, on the 50-yard-line, on a frisbee," said Charlie Bolden, NASA Administrator. 
The landing was the most sophisticated and largest of its kind. Over a period of seven minutes, which NASA referred to as "seven minutes of terror," a series of maneuvers took place to ensure that Curiosity landed safely. Seventy-nine pyrotechnic detonations were required for the release of exterior ballast weights, deploying the parachute, removal from the heat shield, etc. If any of these were to fail, the mission would've failed. 
However, after entering Martian atmosphere at a speed of over 13,000 MPH, then hitting Martian soil, Earth received radio signals for confirmation of its landing after a bit of a delay. It landed at 1:32 a.m. EDT in the exact area that it was supposed to reach -- the Gale Crater.
At that point, NASA engineers celebrated and high-fived over the successful landing. 
"There are many out in the community that say NASA has lost its way, that we don't know how to explore, that we've lost our moxie," said John Grunsfeld, Associate Administrator for NASA's Science Mission Directorate. "I want you to look around tonight. All those folks with the blue shirts, and think about what we've achieved. I think it's fair to say that NASA knows how to explore. We've been exploring, and we're on Mars." 
The project may have cost $900 million over budget, but it turned out to be a great milestone for American space travel. NASA definitely needed this boost after retiring its space shuttle fleet last year, which consisted of the Discovery, Endeavour, and Atlantis spacecrafts. American astronauts were then left to depend on Russia to reach the International Space Station (ISS), but private rocket company SpaceX stepped in to save the day shortly thereafter. SpaceX, which is owned by Elon Musk, successfully launched its unmanned Dragon capsule to the ISS in May. 
Curiosity will now undergo a series of tests before searching for signs of life (or the ingredients for life) on the Red Planet for two years. It will use instruments like a large robot arm, a weather station, a laser that can vaporize rocks at seven meters, a percussive drill and 4.8kg of plutonium-238.

I do remember we had a big push in grade school to learn the system. As a kid it all seemed very easy since it was all 10 based.

Yet you know us, we can't get away from the stupid system we have now!

AND WHY do they convert the olympics into American units for the watchers?? I can easily tell if 50 meters is farther than 45 meters. I do not need to know it was 164 feet 9 and 3/4 inches! Yes I know the conversion isn't correct. I'm just using those numbers to state how stupid it is to do the conversion!

Because there are pros and cons to both systems.

Major con is trying export anything to the rest of the world. I'm pretty sure they don't want to deal with anything in the SAE system. Hell I was a nissan mechanic for a while so bought mostly metric tools, which is a major deterrent to me buying an american car. Even more irritating is when you are working on a car with both metric and SAE, that can really piss you off.

The rest of the world (most, not all) use metric, yes that's true. But that doesn't mean we don't have very valid uses for keeping imperial measurements. Think about carpentry. The metric system SUCKS for that.

I also hate it when manufacturers mix the two standards in cars though lol.

The metric system works great for carpentry, if only the trade used metric instead... how about that 2x4 that isn't 2" x 4", that makes a lot of sense right?

You do realize that the stupid system we now use is mostly binary, and that's the system the stupid computer you are now sitting in front of uses, don't you?

Sometimes the choices were for practical reasons. 360 is evenly divisible by 2, 3, 4, 5, 6, 8, 10, 12, 15, 18, 20, 24, 30, 36, 45, 60, 72, 90, 120, 180. If pizzas were measured in degrees, these are how many people you could have over without anybody being cheated!
