bbbrad:

I am pretty excited to share this. German Designer Roland van Ipenburg has made a widget for How Many People Are in Space! I know right?!
Best part (especially relevant with today’s historic check-in) is that he gets it. He understands why the site (and now widget) work so well:

“Because I like Apple’s philosophy of using a widget for one simple thing and not turning it into an application it’s aimed at just showing the number of people in space, without trying to be some foursquare for space.”

You can go here and get the widget in 3 different flavors! Let me know what you think!
Side note: A NASA astronaut is currently suing Dido, of all people, over the use of the same image I use for HMPAISRN. The image is beautiful, slightly frightening and most importantly Public Domain.

SOIL SOL Question

The following question was on our Bell Ringer recently. I said that the answer was the last one: “some soils have large pores that do not lead anywhere but simply hold groundwater.”

J-Lab says that the answer is the one bolded below: “Some soils have a large volume of pore space, but the individual pores are too small to allow water to pass through. If you selected this one, please let me now and I’ll give you an extra point.

I still think both are correct. Please read this article for further clarification.

Porosity is the amount of pore space in soils. Permeability is the ability of water to pass through the soil. Why do some soils have high porosity but low permeability?

Water with dissolved iron cannot pass through the magnetic field of soils that are rich in magnetite.
Sandy soils dry out quickly, and the pore space fills with air which blocks the downward flow of water.
Some soils have a large volume of pore space, but the individual pores are too small to allow water to pass through.
Some soils have large pores that do not lead anywhere but simply hold groundwater.

As for the real SOL, it really depends on exactly how the question is worded. I would go with the “volume of pore space” one.
