September 29, 2025 [Interview+] This Crazy Pizza Slice Shaped Telescope Obliterates JWST Resolution
James Webb can't resolve Earth-size planets around Sun-like stars. Not just because of the contrast but also because of the diffraction limit. To do that you need a mirror of 20+ meters. But what if you increase the size in just one direction? You get the required resolution but keep the mirror relatively small and easy to transport. This is the idea behind the Rectangular Mirror Telescope.

September 22, 2025 [Interview] Fighting Moon and Mars Dust with An Electric Shield
Dust is a big problem for Moon and Mars. It sticks to everything, breaks things, covers solar panels. So, how do you solve this problem? One possible solution is an electric shield that uses charged surfaces to repel the dust.
