SpaceX’s futuristic Crew Dragon astronaut walkway is ready for US human spaceflight revival
SpaceX has publicly revealed the sleek, minimalist design of the access arm that NASA astronauts will soon use to board Crew Dragon spacecraft, bringing to an end more than half a decade of U.S. dependency upon non-native rockets and space agencies to transport crew to the International Space Station.
After several months of concerted effort in a tent located on Pad 39A property, SpaceX engineers, welders, and technicians have nearly completed the most critical portion of the launch facility modifications and upgrades necessary to return the pad’s human spaceflight capabilities. Known as a Crew Access Arm (CAA), SpaceX will likely complete installation of the Arm by the end of August, wrapping up what is by far the most visible step yet towards returning astronauts to the ISS on American rockets and spacecraft.

This is epic.
Terahertz technology creates new insight into how semiconductor lasers work
Lasers are widely used as high power sources of light operating at a specific frequency. But how does this frequency get selected when a laser is turned on, and how quickly?
Pioneering engineers working with terahertz frequency technology have been researching how individual frequencies are selected when a laser is turned on, and how quickly the selection is made.
The development of specific terahertz equipment has allowed them to investigate this process for the first time. Their results, published in Nature Communications, will underpin the future development of semiconductor lasers, including those used in public and private sector-owned telecommunications systems.
