It is physically impossible to exceed the 70-pound domestic weight limit for a small flat rate box. The interior dimensions (8 5/8" x 5 3/8" x 1 5/8") are ~75.333 in^3. If you filled the box with pure osmium, the densest substance known to man, it would weigh…

How to achieve nanometer precision in space?
The cryogenic mirror actuators on JWST are amazing feats of engineering. Capable of long travel and nanometer precision, able to survive rocket launch, cryogenic temperatures and hard vacuum... they are really impressive devices. And they use flexures!
