Does anyone know what the plane change would have been between Columbia and the ISS (ballpark, I know it moved during the mission)? I could figure out the RAAN of Columbia from launch time, but I don’t know what it was for the ISS at the time.
[Sunday evening update]
Here’s what I added as a footnote to the chapter, as a result of discussion here:
The difference in orbital planes at the time was about ninety degrees. A sixty-degree plane change requires as much velocity as it takes to get into orbit (ignoring atmospheric drag and gravity losses), and ninety would take about forty percent more than that (or about as much as it would take to escape from earth’s orbit from the earth’s surface, again, ignoring those factors), so even if there had been a full external tank attached to the Columbia in orbit and the main engines could have been restarted, it still wouldn’t have had nearly enough propellant to get to the ISS.
As Clark Lindsey reports, there was a drop test of SpaceShipTwo, that had some, but apparently not all of the propulsion system installed. I wonder if it was carrying fuel? One of the issues I discuss in my book is its ability to abort with a failed ignition, because while it can dump the oxidizer, it’s not possible to get rid of the rubber slug. Steve Isakowitz told me that it is designed to land with a fuel load, from a CG/weight standpoint, so it would be interesting to see if they demonstrated that ability.
It’s a dumb reason. He provides reasons why someone might want to claim the moon, but none for why anyone else should pay any heed whatsoever to such a claim.
Even ignoring the fact that it would be a blatant violation of the Outer Space Treaty, there is no traditional or even historical basis on which the nation could claim the entire body, nor is it necessary. Even if we could get an international consensus that off-planet property rights, or even sovereignty claims, are a good thing, we have to establish some criteria for making such claims beyond the fact that we stuck a flag on it four decades ago. Traditional claims, at least in modern times, involve actually occupying and improving the claim. For the U.S. to claim the entire moon without having even bothered to do anything significant on any part of it for almost half a century would rightly be viewed as almost as ludicrous as the Eros claim a few years back. It’s a planet too far.
The Wrights had their first controlled flight of a heavier-than-aircraft on this date in 1903. I had three separate pieces on the event back on the hundredth anniversary, which was also the day that SpaceShipOne first flew supersonic.
[Late evening update, after all the kvetching in comments]
Jeez, Looeeze, people.
OK, first controlled flight of a powered heavier-than-aircraft. Happy now?
The scientists ran their experiment on Arabidopsis plants—a go-to species for plant biologists. The control group was germinated and grown at the Kennedy Space Center (A), while the comparative group was housed on the International Space Station (B). For 15 days, researchers took pictures of the plants at six-hour intervals and compared them. Their results surprised even them: the plants in space exhibited the same growth patterns as those on Earth.
The researchers were looking for two specific patterns of root growth: waving and skewing. With waving, the root tips grow back and forth, much like waves. Skewing occurs when a plant’s roots grow at an angle, rather than straight down. Scientists don’t know exactly why these root behaviors occur, but gravity was thought to be the driving force for both.
So much for that theory. This means the potential for fresh food at ISS, if you’re a vegetarian (or even if not). They should be learning how to do weightless hydroponics. Of course, we still don’t know if animals, and particularly humans, can gestate, or how, and that’s true of partial gravities as well. And we’re not likely to until SSI gets funding for its variable-gravity lab.
