(0:50) - Deployable Solar Sail:

Solar sails are a great alternative to traditional propulsion for deep space travel since it only depends on sunlight as its power source. Recent advances in material science have allowed NASA engineers to develop a solar sail as big as an apartment that can pack itself into a toaster sized satellite. 

(8:00) - Advancing System Security: 

The increasing number of hacks (e.g. Colonial Pipeline) has reignited the pursuit of robust cybersecurity measures and a group of Columbia researchers are offering a no-overhead approach to prevent the most critical system vulnerability: memory attacks.

(14:40) - Cleaning Space Trash: 

Space trash poses a threat against space missions because even the smallest debris can fatally-damage a spacecraft. Embry-Riddle students  partnered with NASA to develop solar sail-powered robots capable of gathering trash and burning it in the atmosphere.
