Has propulsion utilizing solar sail / drag effects of solar panels achieved orbital rendezvous? If yes, is there any utility for clearing space junk?
It has been proposed to use solar panels as solar sails and drag control by alternately feathering panels during different phases of orbit. It is claimed this can alter light pressure and drag enough ...

NASA’s NIAC has awarded phase III funding for Diffractive Solar Sails. Demonstration mission in the works?
Diffractive lightsails use small gratings embedded in thin films to produce diffraction (which causes light to spread out when it passes through a narrow opening).
Diffractive light sails are a ...

What is the optimal planetary sunshade arrangement?
To cool a planet down, one may place a sunshade between the planet and the Sun.
On its own, this is not stable due to radiation pressure, so a simple scheme like a big circular piece of aluminium foil ...

Solar sail for a 3U cubesat: do we have to buy one or can we design one?
We are working on a conceptual design for a 3U CubeSat with solar sail propulsion; we aren’t actually building one or buying one.
However we still need to make decisions like whether to build our own ...
