Whether and when NASA’s Voyager 1 spacecraft, humankind’s most distant object, broke through to interstellar space, the space between stars, has been a thorny issue. For the last year, claims have surfaced every few months that Voyager 1 has “left our solar system”.
Voyager 1 is exploring an even more unfamiliar place than our Earth’s sea floors — a place more than 11 billion miles (17 billion kilometers) away from our sun. It has been sending back so much unexpected data that the science team has been grappling with the question of how to explain all the information. None of the handful of models the Voyager team uses as blueprints have accounted for the observations about the transition between our heliosphere and the interstellar medium in detail. The team has known it might take months, or longer, to understand the data fully and draw their conclusions.
Since the 1960s, most scientists have defined our solar system as going out to the Oort Cloud, where the comets that swing by our sun on long timescales originate. That area is where the gravity of other stars begins to dominate that of the sun. It will take about 300 years for Voyager 1 to reach the inner edge of the Oort Cloud and possibly about 30,000 years to fly beyond it. Informally, of course, “solar system” typically means the planetary neighborhood around our sun. Because of this ambiguity, the Voyager team has lately favored talking about interstellar space, which is specifically the space between each star’s realm of plasma influence.
Voyager 1, which is working with a finite power supply, has enough electrical power to keep operating the fields and particles science instruments through at least 2020, which will mark 43 years of continual operation. At that point, mission managers will have to start turning off these instruments one by one to conserve power, with the last one turning off around 2025.
The spacecraft will continue sending engineering data for a few more years after the last science instrument is turned off, but after that it will be sailing on as a silent ambassador. In about 40,000 years, it will be closer to the star AC +79 3888 than our own sun. (AC +79 3888 is traveling toward us faster than we are traveling towards it, so while Alpha Centauri is the next closest star now, it won’t be in 40,000 years.) And for the rest of time, Voyager 1 will continue orbiting around the heart of the Milky Way galaxy, with our sun but a tiny point of light among many.
Mars. In true colour.
Just so you know, a lot of images of Mars which you’ll see have been manipulated. A lot of them have boosted contrast and saturation. So if you’ve ever wondered – images like this one are what Mars actually looks like.
Why does this not have more notes?!?
YOU ARE LITERALLY LOOKING THROUGH THE EYES OF A ROBOT ON ANOTHER FUCKING PLANET
If you don’t think that’s the tightest shit, you can get out of my face.
i wanted to reblog this so that everyone who sees it can realize just how amazing this is. you are looking at a photograph taken on an entirely different planet. an entire world that has been completely untouched by humanity until only recently. no human in the history of mankind has ever look at those rocks, the soil, the mountains, and the sky until now. and until we finally manage to set foot there for the very first time, no human has ever seen mars from this perspective with their own two eyes or feel the texture of the martian soil on the bottom of their boots. this was only possible by creating a robot, an actual robot, and shooting way out of the reaches of earth and with extremely careful calculations, have it safely land and deploy right where they want it. it’s a robot on another planet being controlled 225 million kilometers away, seeing and studying and sending information for us.
this is the sort of thing you would see in science fiction movies that are only a few decades old. what was only imagination and possibilities back then is now all in this photograph. im looking forward to see what happens in the coming decades
I’m so infatuated by this.
225 million kilometers away and we got it on film that blows my mind
This isn’t what the real Mars looks like, the real one’s in 3-D
