Ice, Ice, Ice

Here’s an arresting picture: a false-colored image the Great Lakes from space, taken on February 19 by a satellite called Aqua, which studies the Earth’s hydrosphere. Worth every bit of the tax money it took to put it into space, and then some.

The notes for the image say that “according to the National Oceanic and Atmospheric Administration (NOAA) Great Lakes Environmental Research Laboratory (GLERL), ice cover on North America’s Great Lakes peaked at 88.42% on February 12-13 – a percentage not recorded since 1994. The ice extent has surpassed 80% just five times in four decades. The average maximum ice extent since 1973 is just over 50%.

“On the day this image was captured, according to NOAA GLERL, the ice concentration covering the great lakes were as follows: Superior, 91.76%; Michigan, 60.35%, Huron 94.63%, Erie, 92.79%, Ontario 20.78% and Lake Saint Claire, 98.78%, making for a total ice concentration of 80.29%.

“The extreme freezing of the lakes is an unusual sight for residents, and has brought tourists flocking to certain locations, such as the Apostle Islands National Lakeshore, where Lake Superior’s thick ice has thousands trekking about 1 mile across the lake to visit spectacular frozen ice caves.”

I’d read elsewhere about the ice caves on Lake Superior. If driving up to northern Wisconsin weren’t such an ordeal in February, it’d be worth going that far to see.

The thought of something as mighty as Lake Superior freezing over boggles the mind. Even in warmer months, at 3 quadrillion gallons that lake is awe-inspiring.

Time for another winter break. The better to admire the snow drifts and icy sidewalks and salty roads and bare trees. Back to posting around February 2 — when I’ll still be able to see those things out my window and under my feet.

I didn’t know until recently that Blind Willie Johnson’s “Dark Was the Night, Cold Was the Ground,” a fitting song for the pit of winter, was included on the Voyager Golden Record. But so it was. Dark is space, cold is the void.

This handy JPL web site tells us that Voyager I, for its part, is now 19+ billion km from the Earth, or more than 126 AU, with a round-trip light time from the Sun of more than 35 hours (so that would be about 17.5 light hours out — not even a light day). The thing’s been flying for over 36 years. Lesson: space is really big.

I did remember that “Johnny B. Goode” went with the Voyagers. Probably because of a SNL skit that mentioned it.

Kreeg Antwoord: You see, it all started on August 20th, 1977, when NASA put up a recording of the sounds of Earth on Voyager I. A two-hour long tape included natural sounds of animals, a French poem by Gaugliere, a passage from the Koran in Arabic, messages from President Carter, United Nations Secretary Kurt Waldheim, music — everything from classical to Chuck Berry.

Maxine Universe: Uh — and you’re saying that the — another civilization has found the tape?

Cocuwa: Yes. They’ve sent us a message that actually proves it. It may be just four simple words, but it is the FIRST positive proof that other intelligent beings inhabit the universe.

Maxine Universe: Uh — what are the four words, Cocuwa?

Cocuwa: The four words that came to us from outer space — the FOUR words that will appear on the cover of Time magazine next week — are [he holds up the magazine: Send More Chuck Berry].

The Unreliability of Comets

Posted on by

Another gray day today, but at least not strangely autumn-like. Underneath the sheltering cloud cover, it was warm and humid.

Above the clouds—really far above them—is Comet ISON (and why can’t famed comets have real names?). Space.com tells me breathlessly, in the tradition of headlines, that “Space and Earth Telescopes to Track ‘Comet of the Century.’ ”

In the text, the article hedges its bets: “Comet ISON was discovered in September 2012, and is due to swoop in close to the sun in November. When it does, it may become as bright as the full moon, visible to the naked eye even in daylight. Or, it may not.”

Maybe the editors are old enough to remember Comet Kohoutek, a previous “comet of the century,” although the previous century, which failed to be aesthetically pleasing for us earthlings. Or maybe the equally disappointing 1986 return of Halley’s Comet.

Side note: Czech astronomer Luboš Kohoutek is still alive at age 78, at least according to Wiki, and probably still adding to the boatload of comets and asteroids he’s already discovered. An astronomer from the time when men were men and comets were named after their discoverers, not the machines that detected them.

Another aside: I’ve never heard of this comet (or maybe I’d forgotten about it).

Rainbow Over Diamond Head

Posted on by

A headline that Google News pulled up for me this morning: “Comic-Con Fans Get World of Warcraft Teaser Trailer. You Don’t.” The implication is that that’s some kind of bad thing, but I don’t see it.

Heat much of last week, then rain in the form of more than one short nighttime thunderstorms rolling through to cool things off. By the next day, most everything had dried off. The pattern: rinse, dry, repeat.

This photo has been captioned many times, but one recent caption is, “Only one human being alive on July 21, 1969 is not in this picture.” Never thought of it that way. Makes me want to read Michael Collins’ memoir, Carrying the Fire.

I have to be content with taking earthbound photographs, and mostly I am. I’ve always liked this one, taken on Oahu in July 1979. The transition from photographic negative to slide to print to digital scan to web page doesn’t really do it justice, but the image retains a bit of the original flavor. I’ve got three boxes of slides made in Hawaii that year and two more made in East Asia in the early ’90s, which are a little hard to appreciate in that format. One of these days, I might convert them directly to digital, but buying the equipment and taking the time are a fairly low priority among all the other demands on my money and time.

For some reason, I didn’t visit Diamond Head State Monument and climb to the rim in 1979. I can’t remember what went into that decision. I hear the view is worth the climb.

The Mighty F-1 Laid Low

Posted on by

I hadn’t heard until today about the expedition that found some Saturn V first stage engines – the mighty F-1 — on the bottom of the Atlantic. The Bezos Expedition site is careful to note that “many of the original serial numbers are missing or partially missing, which is going to make mission identification difficult. We might see more during restoration,” so they could be from any of the missions that used the engines, though I believe they were looking for Apollo 11 relics.

There might be less headline glory in finding something from (say) Apollo 16, but I think it would be just as cool. The expedition site goes on to say that whatever their origin, “the objects themselves are gorgeous.” Bet they are. They’ve gone to the Kansas Cosmosphere and Space Center for stabilization, so maybe they’ll stay there for display. That place would be worth going to that corner of Kansas to see, F-1s or not.

Seems that Amazon boss Jeff Bezos paid for the expedition, or at least much of it. Good for him. It’s the kind of thing that billionaires should spend some of their money on. That and the 10,000-Year Clock.

The Forgotten Cosmonaut

Got a packet in the mail recently telling me about the Vanderbilt 2013 Reunion and Fundraising Opportunity. Actually, those last three words aren’t in the title of the event, but they’re more than implied. One of the “class goals” is fundraising to the tune of $1,000,000 “with 32 percent class participation.”

I don’t think 32 percent is necessary. Between the right four or five alumni of my class, that much could be raised right away. But the school might have to name something after them.

Anyway, in an effort to drum up some nostalgia for the early ’80s, the invite includes the following verbage: Motorola debuts mobile phones; Who’s at Exit/In tonight?; Sally Ride is 1st woman in space; Meat sticks at Rand; Campus computer use up 100%; Housing lottery equals stress.

Some of those are self-explanatory, and others are enigmatic if you didn’t attend VU, such as “meat sticks at Rand,” which I will leave to the readers’ imagination. But I kick into copy editor mode at that business about Sally Ride, first American woman into space.

Is it too much to ask someone with a Vanderbilt education know who the first woman in space was? Valentina Tereshkova, forgotten again here in North America. But I expect she’s honored enough at home, even without the Soviet Union. Remarkably — I just checked — she’s still alive, and not even that old (76). I guess spacefaring in the early days was a young woman’s game.

Bang, Zoom! Straight to Pluto!

Comet? What comet? Can’t see no stinkin’ comet. Of course, it’s been overcast for a while hereabouts, but maybe when things clear up, I’ll go look for it. Trouble is, suburban lights have a way of washing out the sky, including stray comets, unless they’re really bright. I was amazed to be able to see Hale-Bopp, but it managed to be visible even on the North Side of Chicago.

What’s up with that name, Pan-STARRS (which I’ve also seen as PANSTARRS)? I checked, and it was discovered using a telescope of that name. I was under the impression that comets are named after their discoverers, but perhaps an automated system uncovered this one, though you’d think whoever was directing the research would be honored with the name. Then again, if the scan were really automated, you could call the telescope a sort of discoverer.

Today’s odd bit of information (space related, because checking on Pan-STARRS took me on some tangents): the New Horizons spacecraft, now much closer to the planet Pluto than Earth — 6.76 AU v. 26 AU — carries a visible and infrared imager/spectrometer called Ralph, and an ultraviolent imaging spectrometer called Alice.

Tidbinbilla

Christmas Eve 1991

A summer’s day. I bought sun block today. Along with Pete, his brother, and his brother’s enormously pregnant wife, we went to the Tidbinbilla Deep Space Tracking Station southwest of Canberra to take a look at the big dishes and the small museum, which emphasizes Australian, Japanese and European efforts to explore space.

Had a “Jupiter Dog” at the Moon Rock Café. You’d think there would be a Great Red Spot on it somehow, but it mainly featured onions and diced tomatoes (maybe one of those tomatoes counts as the spot). Returned to town the way we had come, winding through hilly bush and flatter farmland. Sometimes emu and kangaroos bounded across the road ahead of us.

Postscript 2012: The formal name of the place is the Canberra Deep Space Communication Complex, and it still functions as one of three stations operated by NASA to keep track of far, far away spacecraft, with the other two in California and Spain. “This strategic placement permits constant observation of spacecraft as the Earth rotates, and helps make the Deep Space Network the largest and most sensitive scientific telecommunications system in the world,” notes NASA.

Space: 2012 (and an Oddity from 2006)

Well worth a look: NBC News, the Year in Pictures. Space edition, which includes the likes of Felix Baumgartner before one of his epic, insane jumps from the edge of space, the aurora australis as seen from orbit, an ethereal enhanced-color image of Saturn, nebulae, views of the Earth and more.

“One of the strangest satellites in the history of the space age is about to go into orbit,” noted a NASA press release. “Launch date: Feb. 3rd. [2006] That’s when astronauts onboard the International Space Station (ISS) will hurl an empty spacesuit overboard.

“The spacesuit is the satellite — ‘SuitSat’ for short.

” ‘SuitSat is a Russian brainstorm,’ explains Frank Bauer of NASA’s Goddard Space Flight Center. ‘Some of our Russian partners in the ISS program, mainly a group led by Sergey Samburov, had an idea: Maybe we can turn old spacesuits into useful satellites.’ SuitSat is a first test of that idea.”

I understand that SuitSat broadcast its position for a couple of orbits and eventually burned up upon entering the atmosphere. The rest of the release is here.
