A thousand light years from Earth, something enormous is happening. The Hubble Space Telescope has captured images of the largest protoplanetary disk ever observed, a swirling mass of gas and dust that spans nearly 640 billion km. To put that in perspective, it’s 40 times wider than our entire Solar System, from the Sun to the outer edge of the Kuiper Belt where comets drift in the darkness.

Rethinking How We End A Satellite's Mission
At the end of their lives, most satellites fall to their death. Many of the smaller ones, including most of those going up as part of the “mega-constellations” currently under construction, are intended to burn up in the atmosphere. This Design for Demise (D4D) principle has unintended consequences, according to a paper by Antoinette Ott and Christophe Bonnal, both of whom work for MaiaSpace, a company designing reusable launch vehicles for the small satellite market.

Turning Structural Failure into Propulsion
Solar sails have some major advantages over traditional propulsion methods - most notably they don’t use any propellant. But, how exactly do they turn? In traditional sailing, a ship’s captain can simply adjust the angle of the sail itself to catch the wind at a different angle. But they also have the added advantage of a rudder, which doesn’t work when sailing on light. This has been a long-standing challenge, but a new paper available in pre-print from arXiv, by Gulzhan Aldan and Igor Bargatin at the University of Pennsylvania describes a new technique to turn solar sails - kirigami.
