Playing Asteroids projected onto a hill a few hundred metres away with a FRICKIN LASER BEAM was a truly remarkable experience. Thank you @seb_ly! ❤️🙌 #emfcamp

I was so excited I forgot to add the video! This is a single 7.5W laser running at 30kHz sample rate, the tracking is essentially a travelling salesman algorithm. Oh and the laser control software is all Seb’s too. Go check out Seb’s work! Truly terrific stuff https://seblee.co #asteroids #laser #emfcamp

A video at night looking over some grass and miscellaneous tents toward a dark hill top. From the top left of shot there is what appear to be several tightly focused light beams. The video zooms a little to reveal the angular graphics of the 1979 game Asteroids being played on the hill, which is a few hundred metres away. You can hear pew pew sounds and clicky controller noises and also some miscellaneous background chatter

"'It’s difficult to say exactly how many asteroids will be lost… but preliminary results suggest that for every five near-Earth asteroids we discover, we lose one solely due to constellation interference. That’s if no mitigation measures are taken.'"

Game cover artwork and movie artwork used to be so great. Modern cover artwork or AI artwork is so uninspired in comparison…

"In general, space rocks larger than a kilometre can’t rotate more than once every 2.2 hours because they would break apart. But smaller #asteroids like #2024BX1 can withstand much faster spins because they are more compact."

Presenting DUST OF OSIRIS, watercolor and ink, 12x12”. Inspired by the Egyptian decorative motifs, the Egyptian Revival movement, and a high-res photo of the opened OSIRIS-REx sample container, containing dust from asteroid Bennu. This has been a labor of love for me, I hope you enjoy it!

Earth's gravity may be our best defence against large asteroids, a new study suggests. The study shows that Earth's strong gravity can break up asteroids before they hit the surface, reducing the risk of a global catastrophe. The researchers used computer simulations to model the effects of gravity on different types of asteroids. https://www.msn.com/en-ca/news/technology/earth-s-intense-gravity-is-built-in-defense-against-large-planet-killer-asteroids-study-suggests/ar-AA1m7cOI #earth #gravity #asteroids

Unfortunately, our monitoring systems for watching the sky 🔭 are not evenly distributed.
