Anyone else remember seeing that special on TV a few years ago called "95 Worlds and Counting?" It featured "water skiing" on Titan, spelunking on Triton and other possible adventures in the outer solar system. I think the show could be updated to include skiiing on Pluto with those mountains we saw Wednesday. I'm sure the slopes would include plenty of black diamond ski trails

I don't recall the interval between the two Pluto discovery photographs, but I'm pretty sure it was hours or at most a couple of days, not months. The original uncropped photos posted by rtphokie had the dates January 23, 1930 and January 29, 1930 respectively. So a weeks time. These objects are moving near the same speed or slower than Pluto. The largest is the biggest mystery. I wouldn't expect an asteroid because of the high inclination. Pluto is pretty close to the ecliptic here, hence why Tombaugh was able to find it. But this large object is moving somewhere around 60-70 degrees to that. Its possible its dust but it seems to have registered roughly the same shape in each frame. Could be a comet, could be dust. I agree that it seems strange that it would go unnoticed because it is brighter than Pluto in these frames. Heres a Stellarium shot from January 23, 1930 with as much detail as I can add in. It unfortunately does not include asteroids, KBOs, SDOs, or anything else other than planets and stars unfortunately. Here is Celestia with all solar orbiting body orbits in the standard version visible. -------------------- |

Depends almost entirely on the distance. NEOs at their closest can whiz by VERY quickly from our perspective, main belt asteroids not so fast. I don't recall the interval between the two Pluto discovery photographs, but I'm pretty sure it was hours or at most a couple of days, not months. Those pics have an extremely small field of view. Those two images were taken 6 days apart. Jan 23 and 29, 1930 |

Could be a comet, could be dust. It's dust. It only takes a few minutes to check the original plates - this is the corresponding region from the Jan 23rd plate: Familiar lesson here: always go back as far as you can to the original data! What's intended for public consumption is often not reliable for serious analysis. |

Remarkably smart "social media" questions this time around!

I put a post on Alan Stern's facebook feed thanking him for continuing the raw image release policy. Please Like it to thank him for continuing to include us in this amazing journey!

MOD NOTE: Several posts hidden due to violations of several rules under section 2. Please review the Rules and Guidelines. Even old hands should do that every so often just to keep them fresh in their minds.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

I'm waiting for an announcement of the Alan Stern Pluto Orbiter Mission...

A fine gesture across the void, from a European orbiter to a US probe:
