Back in July, Maggie Masetti at the NASA Blueshift blog offered readers a thoughtful gesture: send in a postcard with your name and address and request an oversized retro postcard from the Goddard Space Center, and they'll send you one. So that's what I did.
Here's what came today in response.
On the reverse is a cordial message from Katja Pottschmidt, who among other tasks studies X-ray binaries. Thanks, Dr. Pottschmidt!
As far as I know, the offer still stands, so if you want a little piece of space science goodness in your mailbox, you'd best go send them a postcard ASAP.
