Incredible Photos From Spacecraft’s 4 Billion-Mile Journey

Last week, a small spacecraft named Rosetta caught up with Comet 67P/Churyumov-Gerasimenko. Their rendezvous took place between the orbits of Mars and Jupiter and marked the end of a 10-year, 4 billion-mile chase.

The journey took Rosetta along a tortuous, dizzying path as it traveled from Earth to its faraway, 2.5-mile wide target. Looping around Earth and Mars several times, the European Space Agency’s probe gathered gravity assists that would help sling it to Comet 67P/Churyumov-Gerasimenko. Now about 62 miles (100 km) from the two-lobed object, the spacecraft is sending detailed images of the comet’s surface. Over the next six weeks, it will descend to a point just 18 miles (30 km) above the icy chunk; then sometime this fall, Rosetta will deploy a lander named Philae to a yet-to-be determined site on the comet’s surface.

Rosetta will remain in orbit around its comet through the next year, gathering data about these spectacular travelers that have fascinated and terrified Earthlings for millennia.

But the spacecraft wasn’t exactly sleeping as it raced to catch the comet with the really long and tough-to-pronounce name. As it swung around planets and brushed by asteroids, Rosetta was awake and shooting photos (browse through the images here). Some of those are in the gallery above, and are absolutely gorgeous. Among them are Mars, set against a glittering Milky Way backdrop, a crescent Earth with the south polar vortex just visible above Antarctica, and a new view of the moon.

And below, I’ve included a recent image taken by Rosetta of its home for the next year.

  1. If I had any say in where I would put the lander I would park it between the two lobes near the area where it looks like a snow drift. I would think that that area is fairly protected and seems to have a lot of material available that is not contaminated with any other material. If we could only land a Human there, Then we could have made a Comet material Snowman!!!
    Ha Ha! Any other ideas on where it should land?!
    Thanks for a WONDERFUL article, Again.

  2. Amazing achievement and stunning photos! I would love to know the ‘g’ value for this object. It must be a minute percentage of what we are used to for major natural space objects which would make the orbital velocity very slow indeed. Interesting.

  3. I am thrilled to hear that Rosetta, the spacecraft saying–Hello to the Dog’s Bone comet-like asteroid in the long, deep space as we wave our hands to greet!!!

  4. As I have seen the Hubble photos of Pluto in mud-like color; I have my theories to point-out that Pluto appears to have mountains and craters in dark and light brown in my mind.

  5. Wow . . . 4,000,000,000 Miles from Earth which is over 1/2 hour that light/waves need to travel to reach earth.
    How is the manipulation of Rosetta in relation to the comet handled by the controllers on earth … ?

  6. I have the same question as kurt?! I can’t even play a video game with a 3 second delay, how are these guys actually going to land something with that huge of a delay? Wouldn’t it just be a compute and hope?

    on a side note, this comet kind of looks like a nutsack…

  7. Can you provide more info on the water and bio probes and sensors. Is it a basic spectrograph or something more advanced? Also can you discuss the software used for system control. I am dying to know how automos the probe is ? Finally you must mention the cost given the ebola and unemployment situation. This is just an amazing piece of science research. Bravo.

  8. That TV show was the worst one I’ve seen. It didn’t mention that the lander bounced twice and finally landed in the shadow of a cliff, or that the tethers didn’t work. Was the show prerecorded?
