30 November 2014

I was reading the BBC news tonight and the mentioned that it is the 46th anniversary of the release of 2001: A Space Odyssey so I had to dig it out and watch it yet again. It is one of a handful of movies that I return to time and again.

While watching the opening of the space scenes I saw the picture of Haywood's space capsule in transit from the orbiting transit point to the Moon and thought that moon looks close to the current state of the Moon today, not that I have seen the Moon today or any time in the recent past.

So after the movie was over, which was a long 2 1/4 hours but worth it if for the music alone, I dug out my Observers Handbook and did verify the similarity so fired up Stelarium to grab a quick image.

Continuity leaves something to be desired here. When Hayward approaches the transfer station on his urgent fact-finding mission to the Moon the Moon is just approaching full so for it to be just past First Quarter when he leaves the transfer station he must have stayed there at least 20 days.

I also found it interesting that there was an intermission in the middle of the Jupiter mission.

Blogger is behaving strangely. I tried to add streaming images from ISS to the footer and it has deleted all of my sidebar and footer content. But when I preview my page template all of that content appears. When I delete the new content sometimes the old template material is displayed but mostly it is not.

During working hours the stream shows activities going on within ISS and has ISS to cround communications voiceover. During sleeping hours the video alternately shows earth for 45 minutes and darkness, with maybe some lightning flashes or city lights, for 45 minutes.

It is interesting to see solar eclipses happening every 90 minutes as ISS goes into Earth's penumbra and then quickly into its umbra and then reverses the process 45 minutes later.

12 November 2014

I am watching the coverage of the Rosetta mission this morning. It puts me very much in mind of the experience of the first manned Moon landing.

The team in the European Space Operations Centre seems much smaller than the NASA teams at the Kennedy or Houston space centers. And their coverage of the event doesn't seem to have as much scripted hyperbole kissing up to a congress.

0400 — We just got confirmation that the Philae lander has separated from Rosetta and is being pulled toward 67P's surface by its gravity, a trip that should take seven hours. There was a problem with the pressurized gas that was supposed to drive the screws in the lander's feet that were to anchor Philae to the surface so now it is all up to the harpoon in its belly that will fire as soon as it makes contact with the surface. Hopefully it will be enough to hold the lander on the surface.

0424 — Early this evening the ESOC had been a big room of empty chairs. About an hour before Philae release it looked like they were doing a shift change and the room filled with both shirts and suits. Now that they have received confirmation of release the ESOC is a ghost town.

0515 — Someone brought in what looked like a stuffed M&M-like alien and had him sitting on top of one of the low, mostly empty, bookcases where he would occasionally appear on screen. Some Scrooge suit just went into the ESOC and picked it up and took it to the back of the room and hid it behind a monitor then left. Bring back the alien.

0937 — The neatness Gestapo are at it again. First the garbage cans had to be moved out of camera sight. And now all the food and other personal items that were on top of the bookcases has had to be moved into the dark recesses of the middle shelf where they are less visible. I wonder what they had to say about the lead scientist who has been appearing in interviews in shorts and a Hawaiian-type shirt covered with scantily clad women and who is himself covered from wrists to elbows and ankles to knees with solid tattoos.

The alien reappeared for the landing but about two hours later someone marched in and took him completely out of the room.

This has been an audacious mission. It launched in 2004 and the satellite slept for 2 ½ years while it received 10 gravity assists to boost its orbit to reach 67P.

It woke up in November and nothing was really known about the shape, makeup or gravity of the comet. All that information was gained while on orbit flying around an object that was changing the orbit of the satellite as it flew around. And now they have successfully landed a lander on the comet and are doing science there.

Good job, ESA!
