NASA: Senior Review 2016

Yay, NASA Senior Review is out: SeniorReviewReport_2016 tl;dr – everyone is above average, they’re good enough and we like you. bad news: per AAAC meeting earlier, there is not enough $ to actually pay for all these lovely toys, so something will have to give, somewhere. Someone at a high enough pay grade to take…

As of this morning we have discovered over 1,500 exoplanets, planets orbiting stars other than the Sun.

A research group at Lawrence Livermore National Laboratory has produced ultrastiff ultralowdensity metamaterials by 3D printing of microarchitected microlattices. This is very cool – they do additive 3D printing using microstereolithography with nanocoating and postprocessing and can make self-similar lattices with densities varying by several orders of magnitude in bulk density but near constant stiffness.…
