Neither Here Nor There

Archive for September, 2010


I came across this list at Wikipedia (not surprisingly, about spaceflight).  It lists *every* human spaceflight since April 12, 1961 (Vostok 1).  And the total surprised me:


Only 282 flights with humans in over 49 years.  Less than 6 per year on average.  This includes 3 flights from the X-15 program and 3 flights from SpaceShipOne  — both non-traditional spaceflights.

After Yuri Gagarin orbited the Earth almost 50 years ago, I wonder how many flights the people at Roscosmos and NASA thought there would be at this point.

The Earth and the Moon

@NASAhistory just posted to twitter that this pictures was taken 33 years ago today:

I love pictures like this, the Earth and the Moon in one frame.  This image was taken by Voyager 1, the first to look back from such a distance (7,250,000 miles away), and the right equipment, that the Earth and Moon could be seen together as a pair. There’s more information about the photo here.

A more recent photo was taken by the MESSENGER spacecraft en route to orbit Mercury:

This photo was taken from about the same distance from the Earth as the orbit of Mercury and was just recently released. Many people have remarked about its resemblance to the Pale Blue Dot photograph (also from Voyager 1).

Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. –Carl Sagan (from his book Pale Blue Dot: A Vision of the Human Future in Space)

Neat Mac Tip

I like sites like, but I find that there are usually nice suggestions, but that I really pick up on some of their suggestions immediate. But this one I really got me and is turning out to be very useful.

The tip is: use “option” on a mac to open a new window in that application. It’s something I usually like to do in Chrome or Finder — but now I can do easily with a keystroke. (I try to keep my hands on the keyboard as much as possible).

The only problem: Getting your fingers in the right spot isn’t easy — I’ll have to work on that one.
