Has CubeSats Time Come?

Can CubeSats do quality science? For one group, yes NewSpace Journal
“While interest in CubeSats–spacecraft as small as ten centimeters on a side and weighing one kilogram–has grown in recent years, one challenge facing the community of CubeSat developers is whether such spacecraft can perform useful missions, beyond education (many satellites are built by student groups) and technology development and demonstration. For one group at the University of Colorado, it appears that CubeSats can carry out research worthy of publication in scientific journals.”
