GOOD LUCK! I can hardly believe the day has finally come – it’s been a long time!
Update: Landing confirmed. Harpoons did not fire, investigation in progress. The one way radio travel time is a bit over 28 minutes – each way.
ESA is reporting all is well with Philae is in good shape despite the harpoons.
If you see no video above it is because ESA isn’t broadcasting at the time.
Check out the Rosetta Blog and for last second updates.
Just three days away.
This is Friday’s press conference with Rosetta mission experts hosted by Emily Baldwin, ESA space science editor / Rosetta Blog
The video is in distinct segments of about 15 minutes and questions at the end.
Introduction and mission plans fellowed by Science at 15 minutes, Landing at 30 minutes and Summary at 45 followed by questions.
When NASA astronauts and any support staff that might have to quickly exit the had to get off the 60 meter/195 foot level of Launch pad 39A and B at Cape Canaveral they would do so by using slide-wire baskets.
The baskets could hold three people could get in the baskets at the Fixed Service Structure and travel 366 meters/1200 foot to safety in just about 30 seconds. The braking system was a drag chain braking system and a catch net.

Voyager’s look at clouds on Neptune. Credit: NASA Jet Propulsion Laboratory / NASA Planetary Photojournal
The bit of an interlude in the ESA’s Comet watch blog is a good time to look at some of Voyager 2’s images of Neptune. This is one of my favorites. I don’t really know if there is more than coincidence that the New Horizon’s spacecraft crossed the Neptune orbit 29 years almost to the day after Voyager started its Neptune encounter.
There is a lot of comparisons being drawn between the New Horizon’s and Voyager missions. Hey I’m on board with it. If I had my way there would be a “Le Verrier” or “Galle” spacecraft, a Neptune analog of the Cassini spacecraft in orbit right now.
In case you were wondering what was going on with Rosetta, everything is fine. Mission managers are looking at images from as close as 50 km trying to select the best landing spot. New images will be posted shortly.
This image comes from NASA’s Solar System Exploration (and Planetary Photojournal) site:
This Voyager 2 high resolution color image, taken 2 hours before closest approach, provides obvious evidence of vertical relief in Neptune’s bright cloud streaks.
I remember this quite well. I was watching the video data being rebroadcast on the ham bands and I was decoding them on a ROBOT 400 SSTV converter – good times!
Truly an epic mission.

A little NASA history from 31 July 1964. If you can access YouTube on your television I can recommend doing so.
20 July 1969. This is part 1 of 15.
If you have some time, you can read Mission Transcript: Apollo 11.
Spoiler alert: The Eagle has Landed – page 178 of the AS_11 CM.PDF link.
20 years? Already? Hard to believe but true.
Comet Shoemaker-Levy 9 impacted the planet Jupiter 16 July 1994. The comet broke up under the influence of the gravitational pull of the planet during a close pass in July 1992 (was within the Roche limit) and impacted two years later.
The image above is one of many images you can find at our Comet Shoemaker-Levy 9 page. Be sure to visit the links for the legendary Eugene Shoemaker too.

A near miss by a Carrington level storm, by a week! Eventually, it seems bound to happen.
The Carrington Event of 1859
Until now we thought only big things had rings, really big things like Saturn and Jupiter. Turns out rings can occur around much smaller objects, like the asteroid Chariklo.
Chariklo or more formally 10199 Chariklo is a minor planet orbiting beyond Saturn, in fact its orbit is such it gets out to the orbit of Uranus.
Chariklo is only about 248 to 258 km / 154 to 160 miles in diameter (plus or minus 18 km), it has not one but two ring named Oiapoque and Chuí. It is almost unbelievable the rings could be detected, especially since Charilko was found only relatively recently, in February of 1997 by James Scotti of Spacewatch.
NOTE: Not sure what is going on with the Space X launch scheduled for 20:58 UTC (4:58 EDT). The last I have heard is there is an 80 percent chance of launch (from KSC) due to weather. There will be a press conference in a little while, I hope to be back with more news then.
Space X update:
Sounds like there are adding a “late load” to the spacecraft right now and are attempting to have things ready tomorrow.
Space X is go for launch.
