Surveys

And just to demonstrate that I can talk about something other than the Blogathon … 

I always feel duty-bound to answer phone surveys. My wife’s a statistician, for one thing. For another, I feel like my point of view is probably askew from the mainstream in a number of areas (oh, to be a Nielsen Family), and it’s nice to get a bit of representation here.

On the other hand, I’m well aware of the concept of push polls and the like, and so I’m always hypersensitive to biased questions when I’m on a phone survey. I’m also sensitive to social engineering type attacks, and always consider whether the info I’m being asked for could be to my detriment if I give it out.

The result is, unfortunately, that I spend more effort mentally parsing the questions and answers as I do coming up with responding accurately. Which is a shame because … well, it is.

If Man first walked on the Moon today

A nice video (via Les, with good commentary) put together by Slate, speculating on what media coverage of the first Moon Landing would have looked like if it were 2009, not 1969.

 

Yeah, I suspect so.  While there may be some “Golden Age of News” blinders in our memory, the fancy-shmancy graphics, the man-on-the-street commentary, story arc titles, panels of talking heads, and Twitter feeds (fergoshsakes) all look like the sort of non-information dreck that’s taken over TV news. All that was missing was someone interactively drawing orbits around the Moon on a huge touch screen panel, and someone on Fox speculating that it was all a hoax to distract attention from Obama’s birth certificate …

The Google Maps bit, though, was clever. That’s information, folks, a way to show a map of what’s happening where on the Moon. There are things the news media can do to inform, rather than entertain. Unfortunately, there doesn’t seem to be much money in that.

20 July 1969

My memory isn’t very good.

Which is to say that I remember lots of facts, but much of my personal memory, my life, tends to be a gestalt, a blur of impressions and fragments. People wonder why I blog, and take so many photos? That’s why.

So my own memory of the first Moon landing isn’t the sharp, crisp, “everyone remembers where they were” kind of thing that so many people (who were alive at the time) is posting today.

I would have been 8 years old — a bit younger than Katherine now, but still in that range. We were with my Mom’s folks up in Santa Barbara, on De La Guerra Terrace. The TV was in the downstairs (virtually a basement, except that they lived on such a slope). And I remember the event happening, and perhaps even some images on their black and white TV (was it actually black and white?) of the landing, and then of the climbing down. I remember my folks, and Nono and Nona, watching the TV.

And that, unfortunately, is that. No remembered great resolve to someday go into space myself, or anything like that. Flickers of memory far less substantial than the video.

A shame, that. Though less of a shame than how mundane it all became, before we decided that, no, spending money on manned space flight was a waste.

The long retreat

One day I fear I’ll have to answer to Katherine — or to her children — about how we let this slip away

The international space station is by far the largest spacecraft ever built by earthlings. Circling the Earth every 90 minutes, it often passes over North America and is visible from the ground when night has fallen but the station, up high, is still bathed in sunlight.

After more than a decade of construction, it is nearing completion and finally has a full crew of six astronauts. The last components should be installed by the end of next year.

And then?

“In the first quarter of 2016, we’ll prep and de-orbit the spacecraft,” says NASA’s space station program manager, Michael T. Suffredini.

That’s a polite way of saying that NASA will make the space station fall back into the atmosphere, where it will turn into a fireball and then crash into the Pacific Ocean. It’ll be a controlled reentry, to ensure that it doesn’t take out a major city. But it’ll be destroyed as surely as a Lego palace obliterated by the sweeping arm of a suddenly bored kid.

The ISS is not a perfect endeavor. But it’s there, and it’s a small sign that we’re still interested in something bigger than our (literally) mundane concerns. It’s an appeal to our better natures, to our ideals — and deciding it doesn’t fit into a given year’s budget cycle shows the flip side to government programs that never seem to die: some things you can’t just give up on for a little while then pick up again when you’re ready.

Unmanned probes are fine, even clever. Manned space missions are flashy. But an orbiting habitat is … humanity’s toe-hold in space. But not nearly important as some Congresscritter’s district’s big defense contract, I guess.

I think of the big “spinning wheel” space stations from SF novels of my youth — or, heck, from 2001: A Space Odyssey — and reading this makes me very sad.

The Mars “Spirit” Rover, is celebrating its five year anniversary. It was only supposed to operate for three months.

These rovers are incredibly resilient considering the extreme environment the hardware experiences every day,” said John Callas, project manager for Spirit and Opportunity at Nasa’s Jet Propulsion laboratory in Pasadena, California.

“We realise that a major rover component on either vehicle could fail at any time and end a mission with no advance notice, but on the other hand, we could accomplish the equivalent duration of four more prime missions on each rover in the year ahead.”

Together, the rovers have driven more than 20km, and returned more than 36 gigabytes of data. This has included a quarter of a million images.

Spirit is exploring a 150km-wide bowl-shaped depression known as Gusev Crater. It has found an abundance of rocks and soils bearing evidence of extensive exposure to water. Opportunity is on the other side of the planet, in a flat region known as Meridiani Planum.

The two rovers are showing their age, but continue to push on. Because of a jammed wheel, Spirit has to drive backwards to go anywhere — but wheel scraping revealed some valuable info about minerals just below the surface dust.

When NASA manages to do something right, the results are amazing. Spirit and its sister, Opportunity, will have the Mars surface to themselves for a while, though — as both NASA and ESA have both postponed their next Mars probes due to budget issues.
