NASA’s Double Asteroid Redirection Test (DART) has one single instrument onboard – the Didymos Reconnaissance and Asteroid Camera for Optical Navigation, aka the DRACO camera. DRACO serves as the spacecraft’s eye and will guide DART to its final destination: impact with asteroid Dimorphos. The stream you’re watching is a real-time feed from the DART spacecraft enabled through the DRACO camera sending one image per second to Earth. In the hours before impact, the screen will appear mostly black, with a single point of light. That point is the binary asteroid system Didymos which is made up of a larger asteroid named Didymos and a smaller asteroid that orbits around it called Dimorphos. As the 7:14 p.m. EDT (23:14 UTC) impact of asteroid Dimorphos nears closer, the point of light will get bigger and eventually detailed asteroids will be visible.

At 7:14 p.m., the DART spacecraft is slated to intentionally crash into asteroid Dimorphos. This stream will be delayed due to the time it takes the images to arrive at Earth, plus additional time for feeding the images to various platforms. For the most up-to-date DRACO camera feed, please tune into the NASA DART Impact Broadcast here: https://youtu.be/4RA8Tfa6Sck.

After impact, the feed will turn black – due to a loss of signal. After about 2 minutes, this stream will turn into a replay – showing the final moments leading up to impact. That replay file will also become available on NASA websites and social media accounts.

DART is a spacecraft designed to impact an asteroid as a test of technology. DART’s target asteroid is NOT a threat to Earth. This asteroid system is a perfect testing ground to see if intentionally crashing a spacecraft into an asteroid is an effective way to change its course, should an Earth-threatening asteroid be discovered in the future.

Watch live as our mega Moon rocket launches an uncrewed Orion spacecraft on a six-week mission around the Moon and back to Earth. During #Artemis I, Orion will lift off aboard the Space Launch System (SLS) rocket, and travel 280,000 miles (450,000 km) from Earth and 40,000 miles (64,000 km) beyond the far side of the Moon, carrying science and technology payloads to expand our understanding of lunar science, technology developments, and deep space radiation.

Liftoff from Launch Pad 39B at NASA’s Kennedy Space Center in Florida is currently targeted for 8:33 a.m. EDT (12:33 UTC) Monday, Aug. 29, at the start of a two-hour launch window.

Through Artemis missions, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term lunar presence and serving as a steppingstone to send astronauts to Mars. We are going.

The Space Launch System is an American super heavy-lift expendable launch vehicle under development by NASA since 2011. As of April 2022, the first launch is scheduled for no earlier than August 2022, pending the success of a wet dress rehearsal test.

Here are my thoughts on attending the 2022 Tesla Annual Shareholders Meeting.

Roel van DijnenI did not realize that India still has such a small economy, smaller then Germany and UK

Eric KlienAdmin.

Roel van Dijnen In related news, India has so far stopped Tesla and Starlink from operating in their country. Governments can, and often do, screw up their economy.

Roel van DijnenEric Klien The screwing up part is rather subjective, imagine the effect on earth when countries like India and Nigeria will adopt the same luxurious lifestyle that we have. But then again, Tesla and Starlink are trying to be part of the solution for that also

Freya WildeRoel van Dijnen even if they did adopt a more luxurious lifestyle, who is to say it would be the same. Wouldn’t that be up to the people there? I have no idea how any country will ultimately act. And I have zero right to guess and interfere. No one doe… See more.

Roel van DijnenFreya Wilde I’m not claiming to have any right to intervene (forcefully) and I sure hope better more sustainable ways of having a great lifestyle will be upon us, preferably sooner rather than later!

And even when shit really wil hit the fan, we humans… See more.

Van’s RV-8 Build Your Own Aircraft PART 9
The Homebuilder: Demystifies the homebuilding process and introduces the RV-8, a project that From the Ground Up will follow for 13 episodes. Expert builder Joe Schumacher offers his inside tips on getting started, while co-host Mark Annick asks the questions every first-time homebuilder will want answered. Follow the pair as they visit a homebuilder working in his garage. Get a feel for space and time constraints, and an appreciation for the process. We’ll also take a look at the tools needed as well as the costs involved.
The Van’s RV-8 is a tandem two-seat, single-engine, low-wing homebuilt aircraft sold in kit form by Van’s Aircraft. The RV-8 is equipped with conventional landing gear, while the RV-8A version features tricycle landing gear. The design is similar to the earlier RV-4, although it is larger than that earlier model.
Richard VanGrunsven designed the RV-8 series as an updated, larger tandem aircraft based on the RV-4 design concept. The RV-8 first flew in 1995 and was first shown publicly at Oshkosh that year.
The RV-8 incorporated changes as a result of lessons learned in producing the popular RV-4 design. The RV-8 airframe accepts larger engines from 150 to 210 hp (112 to 157 kW), including the 210 hp (157 kW) Lycoming IO-390. [6] The RV-8 also has increased wingspan and wing area over the RV-4, as well as greater cockpit width, headroom, legroom and an increased useful load, all with a view to accommodating larger pilots. Like the RV-3 to RV-7 that preceded it, the RV-8 is stressed for aerobatics.
The RV-8 series was intended from inception to include a nose-gear-equipped version designated the RV-8A. The RV-8A was first flown in 1998
As of November 2021, 1,602 RV-8s and RV-8As have been completed and flown.

Everything we know, think and feel—everything!—comes from our brains. But consciousness, our private sense of inner awareness, remains a mystery. Brain activities—spiking of neuronal impulses, sloshing of neurochemicals—are not at all the same thing as sights, sounds, smells, emotions. How on earth can our inner experiences be explained in physical terms?
