Disabled ‘astronauts-in-training’ to fly weightlessly with Zero-G this weekend

The AstroAccess initiative is working to advance disability inclusion in space.

Twelve disability ambassadors will fly weightlessly on Sunday (Oct. 17) as part of an initiative to advance disability inclusion in space.

AstroAccess, the latest mission from the SciAccess Initiative, which aims to make STEM (science, technology, engineering and mathematics) more accessible, will fly a crew of 12 disability ambassadors on a weightless parabolic flight. The flight will take off on Sunday from Long Beach, California, aboard Zero Gravity Corporation’s (Zero-G) “G-Force One” plane, which flies in a parabolic arc pattern that creates short periods of weightlessness in its cabin.

Lucy begins 12-year mission to Trojan asteroids

NASA has launched the first ever spacecraft to visit Jupiter’s Trojan asteroids.

The Lucy mission successfully blasted off at 5:34 a.m. EDT (9:34 a.m. UCT) this morning on a United Launch Alliance (ULA) Atlas V rocket from Space Launch Complex 41 at Cape Canaveral, Florida. An hour later, it returned its first signal to Earth, sent from its own antenna to NASA’s Deep Space Network. Lucy is now travelling at 108,000 kph (67,000 mph) on a trajectory that will orbit the Sun and bring it back toward Earth in October 2022 for a gravity assist.

Over the next 12 years, it will fly past a total of seven different asteroids – a main belt asteroid, along with six Jupiter Trojans. The latter type are asteroids that share Jupiter’s orbit around the Sun, orbiting either ahead of or behind the gas giant.

UK to launch space missions from Scotland next year

This is the first agreement Skyrora has made with a Scottish Spaceport. If successful, this could be the first commercial rocket to go to space from the UK.

The multi-launch agreement with SaxaVord will run for the next decade, giving Skyrora the ability to build towards their target of 16 launches a year by 2030.

#Skyrora is delighted to announce we’ve officially signed an LOI to launch our orbital vehicle, #SkyroraXL, from @Saxavord_Space at the end of 2022!

Astronauts in final training for flight on brand new SpaceX crew capsule

The four astronauts set to blast off Oct. 30 to the International Space Station visited Cape Canaveral over the weekend for a test run inside SpaceX’s new Crew Dragon Endurance spacecraft, one of the last training events before they return to Florida on launch week.

Commander Raja Chari, a U.S. Air Force colonel, leads NASA’s Crew-3 mission to the International Space Station. Chari and the mission’s other three astronauts visited Cape Canaveral Space Force Station Saturday for the Crew Equipment Interface Test, a customary pre-flight training event officials equate to a “test drive” or “walk through” of the spacecraft.

The four-person crew will launch on the third NASA crew rotation flight to the space station, and the fifth human flight on a Crew Dragon spacecraft overall, including a 2020 test flight and the all-civilian Inspiration4 mission last month.

Michael Dell started a billion-dollar tech company in his dorm room —if he was a teen today, ‘I’d be all over’ crypto

When asked about his thoughts on young people starting out in the crypto space, whether it be with digital coins or other assets like nonfungible tokens (NFTs), Dell says that “if I was a teenager right now, I’d probably be all over that.”

In fact, he’s personally invested in a few blockchain enabling technologies, the 56-year-old tells CNBC Make It. “I think it’s super interesting. There’s still a lot to be worked out in terms of what the investment looks like, and what type of investment it is for everyone, but I think it’s interesting.”

That goes for his company as well. “We’re helping a lot of customers implement blockchain at sort of the enterprise level,” Dell says.

James Webb Space Telescope’s Journey to Space [Video]

https://youtu.be/Z4SXarl6i1k The James Webb Space Telescope will be the largest, most powerful telescope ever launched into space. Webb’s flight into orbit will take place on an Ariane 5 rocket from Europe’s Spaceport in French Guiana. Webb is the next great space science observatory, designed to answer outstanding questions about the Universe and to make breakthrough discoveries in all fields of astronomy. Webb will see farther into our origins – from the formation of stars and planets, to the birth of the first galaxies in the early Universe.

A new model to enable multi-object tracking in unmanned aerial systems

To efficiently navigate their surrounding environments and complete missions, unmanned aerial systems (UASs) should be able to detect multiple objects in their surroundings and track their movements over time. So far, however, enabling multi-object tracking in unmanned aerial vehicles has proved to be fairly challenging.

Researchers at Lockheed Martin AI Center have recently developed a new deep learning technique that could allow UASs to track multiple objects in their surroundings. Their technique, presented in a paper pre-published on arXiv, could aid the development of better performing and more responsive autonomous flying systems.

“We present a robust tracking architecture aimed to accommodate for the noise in real-time situations,” the researchers wrote in their paper. “We propose a kinematic prediction model, called deep extended Kalman filter (DeepEKF), in which a sequence-to-sequence architecture is used to predict entity trajectories in latent space.”

NASA Searching for Free-Floating Planets With Artificial Intelligence and Gravitational Microlensing

Exoplanet hunters have found thousands of planets, most orbiting close to their host stars, but relatively few alien worlds have been detected that float freely through the galaxy as so-called rogue planets, not bound to any star. Many astronomers believe that these planets are more common than we know, but that our planet-finding techniques haven’t been up to the task of locating them.

Most exoplanets discovered to date were found because they produce slight dips in the observed light of their host stars as they pass across the star’s disk from our viewpoint. These events are called transits.
