History-Science-Interesting

We at The Planetary Society are aware of how Neil Armstrong’s first step onto the Moon sparked so many of our Members’ lifelong interest in space. We invited them to share their stories about how Armstrong affected the course of their lives.

Neil Armstrong, donned in his space suit, poses for his official Apollo 11 portrait. Armstrong began his flight career as a naval aviator. He flew 78 combat missions during the Korean War. Armstrong joined the NASA predecessor, NACA (National Advisory Committee for Aeronautics), as a research pilot at the Lewis Laboratory in Cleveland and later transferred to the NACA High Speed Flight Station at Edwards AFB, California. He was a project pilot on many pioneering high speed aircraft, including the 4,000 mph X-15. He has flown over 200 different models of aircraft, including jets, rockets, helicopters, and gliders.

In 1962, Armstrong was transferred to astronaut status. He served as command pilot for the Gemini 8 mission, launched March 16, 1966, and performed the first successful docking of two vehicles in space. In 1969, Armstrong was commander of Apollo 11, the first manned lunar landing mission, and gained the distinction of being the first man to land a craft on the Moon and the first man to step on its surface. Armstrong subsequently held the position of Deputy Associate Administrator for Aeronautics, NASA Headquarters Office of Advanced Research and Technology, from 1970 to 1971. He resigned from NASA in 1971.

The full-resolution MARDI images are just as great as we anticipated. As of the moment that I write this, there are 110 full-resolution frames on the ground out of the roughly 1500-image sequence. Most of these are separated in time by several seconds, but among the recently returned data are the first 42 frames, inclusive; we’re on our way to getting the full-resolution movie speaking both in terms of temporal and spatial resolution. Of the first 42 frames, the first 26 are dark, taken before the heat shield separated. This is the 27th. I animated these and the subsequent ones, aligning them all (without rotating them) on a crater at the bottom center of the visible Martian surface, and was really quite amazed at how smooth the descent of the heat shield was. This version is at half the full resolution.

“Well, this was a nice surprise. The MARDI images from Curiosity’s descent to Mars were posted to the Curiosity raw images website several hours ago, but I didn’t notice until someone on unmannedspaceflight.com pointed out that among the nearly 300 thumbnail frames (200 by 150 pixels) there was a single full-resolution image, and it contained the heat shield far below the rover. So cool. It is still mind-blowing to think that this snapshot was taken by a spacecraft flying in the air above a different planet.”

OK, it seems when I was talking to Brian yesterday evening about the Curiosity landing on Mars it was landing, it was about 7pm so I could have watched it but I don’t know how interesting it would have been. Maybe historic though. They have only released a few photographs on Twitter.

Cool but not rainy this morning, very overcast before actual sunrise.

Need to turn off my alarm and just wake up normally. I’ve been turning off the alarm after waking up and just letting myself want to get up before actually doing it. It has worked ok so far, sometimes I’m later sometimes earlier.

Booo! No Visual of the Transit of Venus, all cloudy here.

Checked in all the changes up to this point I have on my project at work, didn’t get an email from Chris or Kem about the things I need to do. I guess I just need to say it’s done and let them do a build.

Got home and Nicki was here, she went and got Subway even after I told her that I think I had enough spaghetti for her too. She left soon afterward, and left her Subway trash on the couch, not good. She also called last night and earlier today about the book she needed for class, obviously there was something that was suppose to come with the Astronomy book but didn’t in the whole book.

Nicki complained about her aches and pains again, seems another part of her body hurts as soon as another stops. She said it is mostly joins and gets bad enough for her to call out of work. She has mentioned it to the Nurse Practitioner and has gotten really no response except to have an MRI. Well seems a bit overboard to her and me as well. I’ve heard of a lot of young people coming down with certain chronic ailments more often than it seemed my generation did.

I made changes to the Beer web-code that now requires a login and should make it so bad things do not happen to the database due to crawlers and robots on the web.

I tried with Brian’s help to get a CVS thing on my site, instead I just found out that I really don’t have tty access to my server. It’s the only way he knows how to make it work, I’ll look around to see if there is another way, I haven’t seen one yet.

Brian and I ended up going to the Movie Stop and picking out some movies, I got the two that came out just today, Safe House with Denzel Washington and Ryan Reynolds along with Disney’s John Carter of Mars. Then I also reserved the next Sherlock Holmes and the Avengers. Used up about half of the $100 card I got for the rebate of my contact lenses that I just received. We then stopped in at Parma and got to see Lauren and Brian had dinner and we both had beers. The sun was out finally today, it was just before sunset and we couldn’t have seen it from the house due to all the trees to the west of us. If we had forgone the trip and went right back and got the solar scope we could have seen something but didn’t feel it was that important. I don’t figure I’ll be around in 117 years when it happens again, but who knows 🙂

This is Big Bang Theory meets beer. Almost literally. If you observe a Guinness that has just been poured, you’ll notice the bubbles actually sinking down the sides, instead of rising like a regular pint. Now – all things being equal, the gas (CO2) that leaves your beer or soda, bubbles up and out of the top because gravity is exerting more force on the the denser liquid around the bubbles.

So why down? Turns out the glass has everything to do with it. The bubbles get trapped on the side, and get pulled down. Pressure forces bubbles up the center, and out. Seems simple enough right?

Well, Irish mathematicians set out to figure out if the glass changes this phenomenon. Bascially, they mathematically modelled the bubbles flow in a pint glass, and what they call – the “anti pint glass.” The bottom of the glass slopes out, or inverted from the traditional pint. [See Graphic]

If you can tell by the little arrows, the bubbles travel downward on the traditional glass, and up on the “anti” pint. Due to higher bubble density at the edges, the central column has less drag force so the bubbles against the wall flow up. There you have it. Guinness bubbles explained by mathematics, and fluid dynamics. Now go, experiment on your own.  [CornellUniversity]
