Welcome home Chernushka

     

On March 9, 1961, Chernushka became one of the first K9 cosmonauts to return safely from orbit.  She made her journey aboard Sputnik 9 with a dummy named Ivan Ivaonvich, as well as mice and a guinea pig.  Ivan received an commendation.  Chernushka did not.

PBS’s Martha Speaks offers a historically accurate simulation of the mission in a browser game in which you can collect socks in space.

Periodic Table

On March 6, 1869, Dmitri Mendeleev presented the first periodic table of elements to the Russian Chemical Society.  Had he not done so, high school students everyone would be unaware that Thallium has an atomic mass of 204.38.  But in case you need a reminder, pick up these nifty periodic table socks from Urban Outfitters.
