Spaceships in movies and TV shows routinely use tractor beams to tow other vessels or keep them in place. Physicists have been hard at work trying take this technology from science fiction to reality. Significant process has recently been made by a team who have developed a laser tractor beam able to attract and repel particles about 100 times further than has been previously achieved. The lead author of the paper, published in Nature Photonics, is Vladlen Shvedov at Australian National University in Canberra.

Other recent tractor beams have used acoustics or water, but this one uses a single laser beam to control tiny particles about 0.2 millimeters in diameter. The tractor beam was able to manipulate the particles from a distance of 20 centimeters, shattering previous records. Despite this incredible distance, the researchers claim it is still on the short end of what is possible for this tractor beam technique.

SpaceX simulated an in-flight emergency Sunday to verify the company’s Crew Dragon spacecraft has the capability to catapult itself away from a failing Falcon 9 rocket.

The in-flight abort test demonstrated the human-rated capsule can safely and rapidly fly away from a Falcon 9 rocket experiencing a failure.

As intended, the Falcon 9’s engines prematurely shut down around 84 seconds after liftoff Sunday from the Kennedy Space Center. The automated Crew Dragon capsule fired its own thrusters to escape the rocket before it disintegrated in an orange fireball high over Florida’s Space Coast.

SpaceX completed its last major test before flying astronauts to space on Sunday, in a critical high-speed mission that lasted mere minutes.

Launched on top of a Falcon 9 rocket from NASA’s Kennedy Space Center, the company conducted a test of its Crew Dragon capsule called in-flight abort.

“Overall, as far as I can tell thus far, this was a picture perfect mission,” SpaceX CEO Elon Musk said in a press conference after the test. “I’m super fired up; this is great.”

Cheers, SpaceX 👏

NASA’s Commercial Crew Program can celebrate a big step toward launching astronauts from US soil.

SpaceX will sacrifice a Falcon 9 rocket Sunday in a fiery test a minute-and-a-half after liftoff from Florida’s Space Coast to prove the company’s Crew Dragon spacecraft can safely push astronauts away from a failing launch vehicle, simulating a daring maneuver that would only be attempted on a piloted mission during an in-flight emergency.

The launch escape demonstration could be a spectacle for local residents, rocket fans and enthusiasts along the Space Coast, assuming clear skies and good visibility, according to SpaceX.

An AI assistant with empathy could be exactly what’s needed to provide emotional support for astronauts on deep-space missions to Mars.

NASA’s working with startups like Akin to develop human-like AI systems that could one day play a critical role in supporting astronauts in space.

Musk: “There will be a lot of jobs on Mars!”

According to Musk, you’ll need a crazy amount of cargo capacity to build a human colony on a faraway planet.

“Megatons per year to orbit are needed for life to become multiplanetary,” he tweeted.

CAPE CANAVERAL, Fla. (WTHR) — SpaceX plans to intentionally blow up a rocket on Saturday morning.

The test is being conducted in advance of a piloted flight.

The test, which is scheduled for Saturday morning, will demonstrate the spacecraft’s capabilities to safely separate from the rocket in the event of an in-flight emergency.
