NASA at Saturn: Cassini’s Grand Finale The final chapter in a remarkable mission of exploration and discovery, Cassini's Grand Finale is in many ways like a brand new mission. Twenty-two times, NASA's Cassini spacecraft will dive through the unexplored space between Saturn and its rings. What we learn from these ultra-close passes over the planet could be some of the most exciting revelations ever returned by the long-lived spacecraft. This animated video tells the story of Cassini's final, daring assignment and looks back at what the mission has accomplished.- Buzz Lightyear (Trailer) Pixar has just unveiled the first trailer for the animated film "Buzz Lightyear" (Lightyear), a spin-off of "Toy Story", which is scheduled for theatrical release on June 22, 2022. The story tells the former and intergalactic life of the famous character, a true ranger of space. To infinity and beyond !
- Inspiration4 space tourists open the observation dome Inspiration4 space tourists Jared Isaacman, Hayley Arceneaux, Sian Proctor and Chris Sembroski, open the cupola of the Dragon capsule for the first time allowing them to observe the Earth. SpaceX's first four space tourists landed on Saturday, September 19, 2021 in the Atlantic Ocean after spending three days in space traveling farther than the International Space Station (ISS), up to 590 km above sea level, spinning in orbit at approximately 28,000 km / h.

- Δεινόσαυροι: η πραγματική ιστορία Καθώς οι δεινόσαυροι κάνουν τα πρώτα τους βήματα στη Σελήνη, ένας γιγαντιαίος αστεροειδής κατευθύνεται προς τη Γη. Η JASA (Jurassic Aeronautics and Space Administration) προσπαθεί να κάνει τα πάντα για να αποφύγει την καταστροφή. Το "Dinosaurs, The true story" είναι μια ταινία κινουμένων σχεδίων μικρού μήκους σε σκηνοθεσία του Paul-Louis Aeberhardt και των μαθητών της σχολής ΙΜΜ (Multimedia Internet Institute).
- A semi diesel engine starts and jumps in all directions This video illustrates what happends when these two stroke semidiesels run out due to too much oil in the crankcase. With my left hand, I block the injection pump, so from that time the engine run on lube oil only, no diesel at all. I have heard lots of stories about this from decades ago but this is the first time, to my knowledge, that it is captured on video. Luckily we had blocked most of the air intake prior to starting and ended at somewhat over 1000 rpm. Max operating rpm is 425-450. With full air supply, I would guess this engine would reach thousands of rpm and I could only guess what would have happened then...

- A Banksy work sold for more than one million euros destroys itself after its sale Was Banksy at the evening sale at Sotheby’s on Friday night? That was the question on everyone’s lips when one of the Bristolian street artist’s paintings mysteriously self-destructed as the contemporary auction drew to a close. Girl with a Balloon (2006) was the final lot of the night, and just as the canvas hammered at £953,829—exactly the same figure as the artist’s previous auction record, achieved in 2008—an alarm was triggered inside the work of art. Onlookers turned just in time to see the canvas slip through its faux-gilt frame and be shredded into pieces.
- Mission 9: Safe Escape In Any Phase Of Flight New Shepard flew for the ninth time on July 18, 2018. During this mission, known as Mission 9 (M9), the escape motor was fired shortly after booster separation. The Crew Capsule was pushed hard by the escape test and we stressed the rocket to test that astronauts can get away from an anomaly at any time during flight. The mission was a success for both the booster and capsule. Most importantly, astronauts would have had an exhilarating ride and safe landing. This isn’t the first time we’ve done this type of extreme testing on New Shepard. In October of 2012, we simulated a booster failure on the launch pad and had a successful escape. Then in October of 2016, we simulated a booster failure in-flight at Max Q, which is the most physically strenuous point in the flight for the rocket, and had a completely successful escape of the capsule. This test on M9 allowed us to finally characterize escape motor performance in the near-vacuum of space and guarantee that we can safely return our astronauts in any phase of flight. Also on M9, New Shepard carried science and research payloads from commercial companies, universities and space agencies. Learn more about the payloads on board here:

- Best way to store an extension cord Dirt Farmer Jay will show you a fool-proof method for winding and storing an extension cord so that we its time to use it, it easily comes unwound and ready to plug in. This tip will save you lots of time and aggravation and require less space to store each extension cord.
- SpotMini Autonomous Navigation SpotMini autonomously navigates a specified route through an office and lab facility. Before the test, the robot is manually driven through the space so it can build a map of the space using visual data from cameras mounted on the front, back and sides of the robot. During the autonomous run, SpotMini uses data from the cameras to localize itself in the map and to detect and avoid obstacles. Once the operator presses 'GO' at the beginning of the video, the robot is on its own. Total walk time for this route is just over 6 minutes. (The QR codes visible in the video are used to measure performance, not for navigation.)

- Mercedes AMG Attempts to Run Over Cop in Times Square Occurred on January 13, 2018 / Manhattan, New York, USA "On Friday or Saturday nights when I have time, I post up in Times Square to film the nice cars that pass through for my Instagram stories while I longboard. So I saw some nice cars passing by and I jumped out of Starbucks for the 4th time and skated after them. I went up ahead to get some nice footage which is when a random Mercedes came out of nowhere and started a rolling burnout. I turned my camera on him and that's the video footage started. Afterwards, I followed the police, but they couldn't stop the car as he drifted down 42nd and got away."
