SpaceX achieves key safety milestone for crewed flight with 10th parachute test

Posted by in categories: materials, space travel

SpaceX is closing out the year with an achievement that should help it keep on track to fly astronauts on board one of its spacecraft next year. The Elon Musk-led space company finished its tenth consecutive successful parachute system test yesterday, an important safety system milestone that should be a good indication that the latest design is just about ready for use with astronauts on board.

The parachute system is what’s used to slow the descent of SpaceX’s Crew Dragon commercial astronaut spacecraft on its return trip to Earth, once it enters the atmosphere. The current design is the third major iteration of SpaceX’s parachute for Crew Dragon, featuring upgraded materials and improved stitching for the best possible reliability and durability during flight.

Yesterday the team completed the 10th successful multi-chute test in a row of Crew Dragon’s upgraded Mark 3 parachute design – one step closer to safely launching and landing @NASA astronauts

This ultracool smart glove for astronauts is like a remote control for robots on the Moon and Mars

Posted by in categories: cyborgs, drones, robotics/AI, space travel

What if astronauts could take a spacecraft to Mars or some other alien planet and, without ever flying through a toxic atmosphere or landing on an inhospitable surface, control drones and rovers to unearth things that would be otherwise impossible to get up close to?

This is the thinking behind the Ntention smart glove. Ntention is an ambitious futuretech startup that was the brainchild of Norwegian University of Science and Technology (NTNU) students who wanted to push the limits of space exploration. They designed this glove, equipped with sensors, as a human-machine interface that lets you mind-control a robot with hand gestures. Now NASA’s Haughton Mars project (HMP) has field tested the glove and found it to be many levels of awesome.

Space-time metasurface makes light reflect only in one direction

Posted by in categories: physics, space travel

Light propagation is usually reciprocal, meaning that the trajectory of light travelling in one direction is identical to that of light travelling in the opposite direction. Breaking reciprocity can make light propagate only in one direction. Optical components that support such unidirectional flow of light, for example isolators and circulators, are indispensable building blocks in many modern laser and communication systems. They are currently almost exclusively based on the magneto-optic effect, making the devices bulky and difficult for integration. A magnetic-free route to achieve nonreciprocal light propagation in many optical applications is therefore in great demand.

Recently, scientists developed a new type of optical metasurface with which in both space and time is imposed on the , leading to different paths for the forward and backward light propagation. For the first time, nonreciprocal in was realized experimentally at optical frequencies with an ultrathin component.

“This is the first optical metasurface with controllable ultrafast time-varying properties that is capable of breaking optical reciprocity without a bulky magnet,” said Xingjie Ni, the Charles H. Fetter Assistant Professor in Department of Electrical Engineering at the Pennsylvania State University. The results were published this week in Light: Science and Applications.
