Curiosity Rover Moves Us Forward. . . And No One Was Watching

NASA made history with another successful Mars landing this morning when its Curiosity Rover landed on the red planet. This is an unprecedented achievement since this is by far the largest rover to ever land. After investing $2.1 billion dollars into the project, and seven agonizing minutes of terror in which the rover entered the Martian atmosphere, NASA's Jet Propulsion Laboratory erupted with cheers and tears of joy when the rover sent a text message that basically said "I made it," sending its first photos on Mars soon afterwards.

There is a bit of a time lag in regards to transmitting info between us and Mars due to the separation in distance, so while we were giving each other high fives and hugs, the Rover had actually been on ground for seven minutes.
 
Curiosity will be the first 21st Century astrobiology mission since the last ones took place in the 1970's with the Viking probes.
   "Today, the wheels of Curiosity have begun to blaze the trail for human footprints on Mars," said NASA Administrator Charles Bolden.

"It will seek to answer age-old questions about whether life ever existed on Mars," he said, "or if the planet can sustain life in the future.—"

Sounds like a crowning achievement, eh? Sadly, there were only a little over 11 million people watching it. Sure, when you hear 11 million, that sounds like a lot of people, but when you consider that the U.S. has over 400 million people on its own, the number doesn't seem that grand.

My roomie wondered why the landing wasn't on local channels or got as much buzz as he hoped, and there's a simple reason: People aren't interested in space the way we used to be. That drive that we had back in the 60's Space Race is gone, mainly in part due to the notion that there's a "been there, done that" mentality to space exploration. And I say this with the embarrassment of knowing that I would've missed the live landing had my roomie not told me the rover was about to land!

Sure, as I said before, this is what, the 3rd successful Mars landing we've made? This is extraordinary! With government funds being cut, a global economy still shaking. . .  and still being able to land what is basically a lab on a planet 154 million miles away with a 60% chance of failure is something worth celebrating.
Now, I know, the Olympics are going on as well, but aren't the Olympics about a celebration of humanity? Is this achievement, not only an American success, but a global one?

Mankind has always looked to the stars, has always strived in taking crazy risks and leaps. Let's be ambitious again, the way we were back in the 60's. . . or the way we were when we were in kindergarten! Come on, you know what I'm talking about. We wanted to be anything and everything, and I'm sure being an astronaut was on the list for a whole bunch of us. :P While this world seems to spiral downhill, there are still some instances where we can look up to the heavens. . . and smile. I mean hey, we might as well since that's our money (yes, yours too) being put into good use. ^_^

Man-made Object About To Leave Our Solar System

To envision the Sun s presence in the Milky Way galaxy  think of a ship plowing through the ocean  b...

Get ready to brainstorm some ideas off of this one, sci-fi people! This past week proved another instance where the genre once again nears sci-fact. I remember reading about Voyager 1 in Astronomy class back in college, and now it's about to make me go "wow" all over again by doing something never done before!

Voyager 1 was built with Voyager 2 in 1977 so we could observe our Jovian planets, Jupiter, Saturn, Uranus, Neptune when they aligned that year. So, Voyager 1 did its job when it flew by then-9th-planet, Pluto in 88. Needless to say, NASA was quite pleased with the successful mission, and they could all call it a day, right? Ahem,  not exactly.

Just because the probe's mission was done didn't mean it would/could stop. And since then, Voyager 1 has sailed across the system with very minor bumps beyond some systems shutting down. So, on June 14, it was announced that the spacecraft had reached the border of our solar system, and will be in interstellar space by the end of the year. That means Voyager will be beyond 

Now, think about it, everyone. The solar system. SOLAR SYSTEM! Lets put in some figures so we can get an idea. Voyager 1 is moving at around 17 kps. That's about 10.5 miles per second, which would equal to. . . hmm, math, math, math. . . 37,800 mph?! This thing is moving! But Voyager 1 was sent out almost 35 years ago. Why would it take something moving so fast to reach the end of our solar system? Well, it's over 11 BILLION mls/ 17.7 BILION kms away. Fun fact, eh?

Wanna know something else crazy? Voyager 1 is still sending a signal back to Earth! Granted, it takes 16 hours for it to reach us, but that's crazy! And as far as NASA can tell, it will keep on sending a signal until its lifespan depletes in another 8 years in 2020. 

As far as Voyager 2 is concerned, well, it's doing pretty darn good too. According to NASA, it's currently 9.1 billion miles away from the sun, and is still sending back data as well. Both crafts are part of the Voyager Interstellar Mission, which is an extension of the original mission. Now the probes are being used to explore the solar system beyond the neighborhood of our local planets and beyond. Ah, science. Isn't it great when the awesome accidents happen?

Get ready to get some insightful info and ideas from this one sci-fi readers and writers. Be sure to check out the article from Digital Journal for more info. You can also look at the Voyager Mission in its entirety on NASA's site
