The top 6 news-worthy NASA JPL missions. Have you heard of Juno, yet?

As my attention is turned more and more to NASA’s Jet Propulsion Laboratory, I have to admit that I’m getting confused with all the various missions. Now that I’m starting to get regular press releases from JPL, they’re all starting to run together. After only last year bemoaning the loss of the Space Shuttle program, it is shocking to discover just how much is really going on in space!

So, while the JPL website lists all its programs in alphabetical order, I thought I’d take the time to list out the more news-making missions here:

Mars Science Laboratory Curiosity Rover

The subject of probably the most intense media coverage since the dawn of the Shuttle Program, Curiosity is only the second full mission and third landing on the planet Mars. The rover is currently en route for Aeolis Mons, the mysterious mountain in the middle of Gale Crater.

Mars Reconnaissance Orbiter

Critical to many missions on and near Mars, the MRO takes  satellite-level photos and readings of the Martian surface. Some of the best pics of the Curiosity landing were taken  from right here on this satellite.

Cassini-Huygens

This one’s a joint venture of NASA and the European Space Agency, orbiting around Saturn and her moons. Any awesome photo you’ve seen in the last ten years of Saturn most likely came from this satellite.

Dawn

It’s not enough to understand the planets, we also need to understand asteroids. Hence Dawn’s mission to understand the geography and dynamism of Vesta, an asteroid nearly the size of Pluto. Soon, it will be turning its attention to the “dwarf planet” Ceres.

Voyager I & II

The furthest-traveled piece of human engineering in the history of mankind, the Voyager mission includes two travelers, each of which has entered into the heliosphere. The heliosphere is the outer edge of the effects of our sun’s solar winds and considered to be the “official” edge of our solar system. Voyager 1 has already breached the heliosphere and entered interstellar space.

Juno

Here’s a sneak preview of one mission that’s only just now getting started in earnest. While we’ve seen a lot of the atmosphere of Jupiter and her tumultuous storms, no one has yet peered into the heart of the gas giant. That is,  until Juno gets there. Juno’s mission and instrumentation involves complex but proven means of pushing the clouds aside for a glimpse of the deep inside of Jupiter. The spacecraft has only just now turned from orbiting Earth to its slingshot trajectory that will propel it towards its destination. Stay tuned!

[VIDEO] New analysis by Cassini scientists reveals amazing dynamism in Saturn’s F-ring

There seems no limit to the things Cassini reveals about our mysterious outer neighbors in the Solar System…

After analyzing the paths of Saturn’s moons, scientists discovered the origins of some of the strange trails they’d previously noticed perforating the rings, specifically the F-ring. It turns out that the moon itself passes through this ring and in so doing, picks up the ice and dust particles that make the ring what it is and carries them along in its wake. Presto! Instant “mini-jet,” as science has known them for some time.

And it turns out that these trails are not just created by moons like Prometheus. Some objects as small as a kilometer wide do the same thing. Check out the last image, which removes Saturn from the shot and emphasizes the F-ring mini-jets. Amazing stuff!

Unfortunately, I cannot embed the video. But I can send you along to the link, so off you go.
