Well, the race is on! Here’s the data on what I know of so far. We’re up to 8 proposals at 24 hours before the deadline. With the enormous sample of two, count ‘em, two data points, we’re on the same curve as we were for Cycle 17 (plotted in black), but scaled down by a factor of 27. The blue line is extrapolating an exponential to the current rate of proposal submission. Both tracks argue for about 30 proposals going in. The scaling factor of 27 suggests that there will be an average of 27 people on each proposal, if Steinn’s argument that the number of proposals is set solely by the size of the community holds. The late-time development of this curve could be way off, however, because there is no way to put one of these together at the last minute. (On the other hand, the proposed experiments are so immensely complicated, that maybe the only way you get them done is waiting until the last minute).

I’ll update the plot if people give data in the comments! (Updated! I cut the blue exponential fit in the revised plot, as it was a lousy match.)

At 2:28 pm Eastern Standard Time, the space shuttle Atlantis left Earth. It was a flawless launch.

It is, of course, hard to describe the experience of watching it go up. I was surprised by just how bright it was. It’s like a mini-Sun, which is roughly right since it burns its liquid hydrogen/oxygen fuel at 3000 C, just a factor of two short of the temperature of the Sun. And, of course, it is loud. Not “hurt my ears” loud. More like “my whole body is vibrating” loud. Very intense.

The whole thing was over in a couple of minutes. I guess the shuttle was eager to get to space. It’s been all dressed up and waiting for days. All too soon the painfully bright light had disappeared. The overwhelming sound had subsided. And the only sign of the absolutely amazing event we’d just witnessed were the slowly dissipating clouds of smoke.

At the end of the day, it is an incredible accomplishment. We have just shot six people into space.

Wow.

- 5 astronauts have masters degrees. 3 were successful football players. 1 has a PhD (and an MD as well, just for good measure). I’m not sure what that says about the requirements to go into space.

- The astronauts go into quarantine for a week before the launch. They don’t want any swine flu in space.

- We are on hallowed ground. This is where humans left the Earth to touch the Moon.

- This is the 129th space shuttle launch. The first was in 1981, for an average of one launch every three months. The whole idea was to make space launch “routine”.

- I calculate that it takes roughly thirty times more energy to get to the space station than it does to get a jet aircraft to altitude. Radius of the Earth: 6,400 km. Altitude of a jet: 12 km. Altitude of the space station: 350 km. (Gravitational potential energy goes as one over the distance.) However, it is to be noted that you want to actually stay up there once you get there, which means you need to be moving pretty fast (specifically, 28,000 km/hour at the altitude of the space station). Kinetic energy goes as velocity squared. This is why you need a kiloton bomb (see my previous post) to get up there.

- As a mission control specialist described launch: “It’s like going over the top of a rollercoaster. Forever.” Actually, that sounds more like what it must be like in orbit: free-fall.

- They monitor everything that happens on the space station. Including light switches and toilet flushes. Think big brother.

- The countdown clock is not linear. There are a number of planned “holds”, where they STOP THE CLOCK and check various systems, and then resume.

- We are roughly 3 miles from the launchpad. This distance was selected by calculating, should the unthinkable happen, how far a 50 pound chunk of debris would fly. We are just beyond that distance, trying not to think about what 40 pounds might do to the media tent.

We are now 1:35:37 from launch.

You can watch the whole thing on NASA TV if you like.

To be honest, I’m surprised by how excited I am. Yesterday we toured the facilities at Kennedy Space Center, and got to see the shuttle up close. It is impressive. Of course, it’s huge. But it’s hard to wrap one’s mind around the simple essential fact: this object is going into space! However, there’s something more primal about all this. I think every kid growing up since the 60s (and presumably well before?) must have had an “obsession with rockets” phase. What could possibly be cooler? They are huge. They go really, really, really fast. They make loud noises. They go exotic places. They are the perfect vehicles for a child’s imagination. As we grow up, most of us lose our fixation. But, as I’ve found out in the last 24 hours, it hasn’t been lost, only misplaced. When you actually see a rocket about to head into space, it’s a completely overwhelming experience. All those emotions come roaring back, and you’re left mesmerized and excited and giddy, just like you were as a 10 year old.

We just took a little break and walked down to wave to the astronauts. They are in the astrovan, an (entirely appropriate, completely antiquated) airstream motorhome. They stopped briefly to say goodbye. Their next stop is the shuttle (and then 300 km up). You might think that this is just part of a media stunt, a final wave for the cameras. But, at the end of the day, these six individuals are about to strap themselves to the top of 1.2 million kg of liquid oxygen/hydrogen (by my calculations, the equivalent of 0.7 kilotons of TNT—a “small” nuclear bomb). This is not all just fun and games; it is a deadly serious enterprise.

We are now 1:53:33 from launch.

There are more photos/real-time updates at our twitter feed, and even more information at the NASA tweetup page.

So we rearranged our schedules, met yesterday in Denver, woke up at 6 am this morning, and are now at Kennedy Space Center with 100 space twitterers. They’ve got a full program here with astronauts and a tour today, and the launch of mission STS-129 to the space station at 2:29 pm tomorrow. The event just started… So stay tuned, we’ll keep you posted. We will be blogging as well as loosing our tweeting virginity @cosmicvariance. You can follow the rest of the gang by looking for #nasatweetup.

Playing with a telescope seems like the perfect way to wind down the Year of Astronomy. And they make very nice gifts (although December delivery is apparently not guaranteed). If you’ve never looked through a half-decent telescope, you will be absolutely astounded by what you see. One forgets that all these things we talk about and see pictures of really exist up there, and are just waiting to be admired!

As this video shows, astronomical observatories are frequently at risk from wildfires, since both tend to occupy dry remote mountaintops. Indeed, close to seven years ago, one of Australia’s major observatories on Mt. Stromlo was nearly obliterated by the fires that raced through the area:

Thankfully, Mt. Wilson survived this round.

PS. You can find a bit more about some of the ground breaking work that was done at Mt. Wilson along with some terrific old Life magazine photos here.
