Purgatory Post celebrates centennial of first liquid-fueled rocket flight

Following a bit of a quiet spell, New Hampshire-based Purgatory Post has released a new 16-sola local post stamp honoring Robert Goddard and the 100th anniversary of the launch of his first successful liquid-fueled rocket. The stamp was issued May 1.

According to a note included with this stamp, Goddard’s experiments proved liquid-fueled rockets could fire continuously; prior to that time, rockets only used solid fuel. Goddard’s work led to further development in Germany, and some of that work later contributed to the success of the USA’s space program.

This was the other piece of interesting mail to which I alluded in yesterday’s blog post, and it’s the last item I have to share with you this week.
