SpaceX’s futuristic Crew Dragon astronaut walkway is ready for US human spaceflight revival

Posted by in categories: futurism, space travel

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.

How cancer cells communicate — and how we can slow them down

Posted by in category: biotech/medical

When cancer cells are closely packed together in a tumor, they’re able to communicate with each other and coordinate their movement throughout the body. What if we could interrupt this process? In this accessible talk about cutting-edge science, Hasini Jayatilaka shares her work on an innovative method to stop cancer cells from communicating — and halt their fatal ability to spread.

This talk was presented at an official TED conference, and was featured by our editors on the home page.

Physicists fight laser chaos with quantum chaos to improve laser performance

Posted by in categories: biotech/medical, quantum physics

To tame chaos in powerful semiconductor lasers, which causes instabilities, scientists have introduced another kind of chaos.

High-powered semiconductor lasers are used in materials processing, biomedical imaging and industrial research, but the emitted light they produce is affected by instabilities, making it incoherent.

The instabilities in the laser are caused by optical filaments; light structures that move randomly and change with time, causing chaos. Removing these instabilities has long been a goal in physics, but previous strategies to reduce filaments have usually involved reducing the power of the laser.

Settling Arguments About Hydrogen With 168 Giant Lasers

Posted by in categories: physics, space

With gentle pulses from gigantic lasers, scientists at Lawrence Livermore National Laboratory in California transformed hydrogen into droplets of shiny liquid metal.

Their research, reported on Thursday in the journal Science, could improve understanding of giant gas planets like Jupiter and Saturn whose interiors are believed to be awash with liquid metallic hydrogen.

The findings could also help settle some fractious debates over the physics of the lightest and most abundant element in the universe.

China will send a rover to the far side of the Moon in December

Posted by in categories: robotics/AI, space

The United States and Russia aren’t the only two nations working hard at realizing their space-faring dreams. China has quickly ramped up its high-flying ambitions in the past couple of decades and late 2018 will mark a real milestone for the country’s space program. The country just announced that it plans on launching a lunar rover to the far side of the Moon in December of this year.

The announcement comes via China’s state-run news agency CCTV, and China seems bullish on the prospect of being the first country to explore the far side of Earth’s moon with a robotic rover.

The mission, named Chang’e 4, follows in the footsteps of its predecessor (you guessed it, Chang’e 3) which saw a rover nicknamed “Jade Rabbit” land on the near side of the Moon back in 2013. That rover ran out of steam in August of 2016, and the model that will be flying to the far side is built largely of backup parts from the Chang’e 3 mission.
