That "something" can be a Ukrainian drone penetrating Moscow's air defences.

In particular, they let in light within the blue and red ranges -- the optimal wavelengths for photosynthesis -- but appear to block ultraviolet radiation from penetrating into their shells where it might otherwise damage their DNA.

She is also part of the science team for NASA's Europa Clipper mission, which recently launched and carries an ice penetrating radar imager developed by UTIG.

These missiles, which are launched from an aircraft, fly close to the speed of sound and carry highly explosive warheads making them an ideal weapon for penetrating Russian bunkers and ammunition stores.

Similarly, they can play penetrating passes forward, or they can use the wide areas and attack with the wingers overlapping.
