NASA Spacecraft Close To Jupiter?

Recently, (in an article provided by NASA) NASA is really close to exploring more from planets Pluto and Saturn, with another departure to another big planet in our solar system, Jupiter. (Click here to read more about NASA!) NASA's probe was launched in 2011, and will reach the planet of Jupiter by 2016 (this year!) It is believed for Juno to head back to earth around June 3rd.This space probe trip has been developing for the past five years in space. Actually, ever since Juno has left to discover the wonders of space, it has not only aimed towards Jupiter, but at exploring the whole Solar System itself.
[The name Juno comes from way behind to the times of the Roman civilization. In the Roman myths, Juno was the wife of Jupiter and Jupiter wanted to hide himself behind the clouds because he caused a lot of trouble, meaning no one would be able to see him behind the clouds. Juno was the ONLY one who had the ability to see through the clouds. In NASA's case, the space probe will also be located beneath the clouds and will be understanding HOW Jupiter was able to become a planet.] (Click here to read more information about the Juno space probe!) 
 Juno has gone at least 1.71 billion miles (2.75 million km) out into space and just needs around nearly 48 million miles before it gets to its desired location. Interestingly, Juno has broken several amazing records to become the most distant solar-powered explorer. Through out the space probe's journey, it has outstandingly been fueled by pure solar energy due to how it is really close to the sun. Juno has consumed nearly 1.3 pounds of fuel during the burn and because of this fuel, it has increased the space probe's speed by 1 foot per second. It is amazing what NASA is trying to do with the largest planet in our Solar System! 

​Thoughts, Ideas and Opinions

My first impressions on this is that I have now  realized how NASA is trying to REALLY go out and explore the wonders of space. They are trying to go on more explorations and find out more discoveries that humans aren't informed of yet. I think as a space industry like NASA, they are doing a pretty good job of what they are doing currently. 
I'm starting to think that all this discovery from NASA is pretty cool and interesting, but the ONE BIG thing that I ask myself is, "Is this practical?" and I also ask myself, "How will we use what was discovered from a big planet like Jupiter, and use it to improve our planet Earth?" Like, all these huge discoveries and explorations are interesting, but like what meaning is there behind them, and what USE will be to all this space exploration? While I was reading the article, I asked myself this because I mean not JUST including this space probe, but other discoveries from NASA that pretty much DOES NOT involve planet earth. 
Overall, besides the negative things I have to say about NASA's space probe Jupiter discovery, I think it is something that will reach out even more later on in the future, and I think there will be more interesting things with this, and ESPECIALLY with one of the biggest planets in our Solar System.
