Weekend Diversion: The Beauty of Humans in Space

"If we die, we want people to accept it. We are in a risky business, and we hope that if anything happens to us it will not delay the program. The conquest of space is worth the risk of life."
-Gus Grissom, who perished in the Apollo 1 fire.

Every once in a while, I try to look past the amazing accomplishments humanity has made in space. And here's a great little piece by Leo Kottke for you to listen to,

Memories Are Made Of This.
Forget about walking on the Moon, sending spacecrafts to all the planets and even out of the Solar System, and instead to just focus on how beautiful some small aspect of it is.

This is the crew picture, courtesy of the ESA, from October 2003, of the International Space Station. In the center of the front row is Astronaut Pedro Duque, who kept a diary of his time in space.

Pedro is also the subject of, in my opinion, the most wonderful picture of a human being in space.

Of course, you can click for the ultra-hi-res version of this picture, but can you tell what's going on here? Water drops in space, of course, become perfectly spherical -- a plenisphere, even -- in a completely zero-gravity environment. And perfect spheres have beautiful optical properties. Let's zoom in and take a closer look.

At the distance of the camera, it inverts the image and distorts it ever so slightly, but puts it pretty much in perfect focus. It's a beautiful combination of engineering, optics, and physics all at once, and this image captures it in a beautiful way for me.

Hope your weekend is full of things just as beautiful to you, and I'll see you all next week!

It was a very cold morning in North Florida (in the teens/low 20s Fahrenheit) as I walked in to class during my second semester of graduate school. I vaguely recall some concerns about the launch of Challenger that morning because of the cold and I believe it was scrapped once before, this highly…

It's Memorial Day weekend, and I won't be blogging over it, as I'm going to be enjoying my long weekend! (And I hope you are, too.) But I'd like to leave you with some reflections on our history of Space Exploration in this country. (This was originally posted last year.) There are wonderful things…
I only barely remember the disaster. It was on this day, but in 1967. In recent years, I've wondered why my memory of the death of Gus Grissom, Ed White, and Roger Chaffee in the Apollo 1 space craft is so vague. I have memories of earlier space activities, but most of those memories are really…

That's a cool trick, using a floating drop of water as a lens. Love to see them do the same trick with a drop of mercury as a perfect mirror.

How times have changed. Challenger, Columbia, TSA.

"Humans in space" is too expensive and dangerous. "Humans in space" is simply playing to popular juvenile sci fi fantasies without producing any SCIENCE.

I think your next post should list all the papers published in peer-reviewed quality scientific journals produced from the ISS and Space Shuttle programs.

And maybe the post after that one should list the papers produced by the unmanned NASA missions.

Go ahead, I dare you!

I've also used that quote by Grissom in a post, and it's worth remembering in each generation. Pioneering will never be risk free, and beauty of the contribution to humanity is absolutely worth every penny.

And Paco... um, fantasies that don't produce science? WOW are you either mis-informed or just plain un-informed! You wouldn't have a PC, a cell phone, satellite TV, weather forecasts, or a thousand other things right now if it wasn't for space agencies attempting to put warm bodies in space for the past 50 years.

Great post!

Just a little nit to pick:the gravity experienced at the ISS is still close to 90% of the gravity experienced at the earth's surface. It's a free-fall but without much air resistance.

@Paco: In many situations humans still beat robots in space. The Hubble telescope could not have been serviced by any reasonable robot. A lot of exploratory work had also been done with the shuttle; it took almost another 20 years before instruments similar to those taken up by the shuttle in the mid-late 1980s were launched as stand-alone missions. Humans do have some use in space. Simply listing publications from manned vs. unmanned missions doesn't prove anything either since each science mission has its own objective and it is available technology and funds which determine whether it's more sensible for a manned or unmanned mission. However, the ISS has been a colossal waste of money.

Leo Kotke: just saw him play last week.
