Today, with the first test flight of the Orion spacecraft, NASA’s trip to Mars begins. If all goes to schedule, humans will walk on Mars in the 2030’s.
Hope I’m around to see it!
I think this is one of the coolest things humanity has done or ever and maybe ever will do. I think these four spacecraft, (two Voyagers and two Pioneers), may very well exist longer than the human race itself.
Voyager 1 Probe May Have Left Solar System
Earth’s most distant spacecraft detected a sharp change in the intensity of fast-moving charged particles called cosmic rays, suggesting it had left the outermost reaches of the heliosphere marking the edge of the solar system. “Within just a few days, the heliospheric intensity of trapped radiation decreased, and the cosmic ray intensity went up as you would expect if it exited the heliosphere,” said Bill Webber, professor emeritus of astronomy at New Mexico State University
The scientists still don’t know for sure, however, whether the probe has entered interstellar space or if it remains in a mysterious in-between region Voyager team members first discovered a few months ago.
“It’s outside the normal heliosphere, I would say that,” said Professor Webber.

One of my favorite websites where I have been monitoring the Voyagers and the Pioneers is HERE. This website is also the best for getting info on viewing satellites in Earth orbit that you can see with the naked eye EVERY NIGHT! It’s called Heavens Above

Sorry, I don’t buy it. No way does a rock from one planet leave that planet, float through space, then land on another. I just don’t buy it. I’m not saying it’s impossible, but I don’t believe happened and I don’t think there is sufficient proof.
So here’s the theory: A meteor hits another planet, Mars for example. The big explosion throws some Mars rocks out into space. In my uneducated opinion, a meteor striking a planet with enough force to throw rock into space would have to be powerful enough to almost destroy the whole planet. Or a volcano shoots some rocks all the way into outer space (my feeble, uneducated brain doesn’t think this is possible at all).
These rocks then attain escape velocity (for the planet Mars), float to Earth, survive burning through Earths atmosphere, and land on the ground. I don’t buy it because first of all, I don’t think a meteor impact or volcano would eject rock into space. Mars has pretty decent gravity and atmosphere (the escape velocity for Earth, if my grade school science memory serves me correctly, is something like 28,000 miles per hour, I’m sure it’s less on Mars, but still up there).
Secondly, any Mars rocks small and light enough to be ejected into space would not be large enough to survive falling through Earths atmosphere.
Thirdly, even if it did happen, there’s no way to know that it is from Mars..If you could prove that it’s from another planet, which you can’t, because this rock doesn’t seem very unique, you couldn’t prove it was from Mars. It might be from Ork, where Mork is from. Even then, maybe he brought it with him, and it didn’t magically fly from planet to planet.
I don’t believe it. If you want to prove to me that the above rock came from Mars, then show me on Mars the exact spot that rock came from. Show me the hole in a Mars rock that the above rock fits into perfectly, like a piece from a puzzle. Then I’d believe it.
Oh yeah, and lastly. Even if it happened all the time, and Mars rocks were just raining down on Earth, why would scientists claim that this could be the FIRST Mars rock to land on Earth, where did this idea come from. “Could be” is right, “could be” is most pertinent words in the article. A loada hooie, I tellya!
