The #Philae  lander's harpoons used nitrocellulose, a well-known explosive which contains its own oxidiser and so in theory doesn't need air to work in. In 2013, nine years after Philae/Rosetta was launched, we discovered that nitrocellulose doesn't explode in a vacuum. Oops.

Watch the video of it not exploding.

One of the Rosetta scientists saw the Wired article in April 2014 and commented, sounding a bit worried. I feel his pain.
