NASA Is Launching Its New DART Spacecraft. To Deflect Asteroids?

Posted by in categories: asteroid/comet impacts, existential risks, space travel

In a concept test for an advanced planetary defense solution.

We are vastly unprepared for the event of an impending, potentially civilization-ending asteroid impact. Knowing this, NASA is developing planetary defense solutions to add to its arsenal of space technologies.

One of these technologies, NASA’s DART spacecraft, is scheduled to launch aboard a SpaceX Falcon 9 rocket at 10:20 Pacific time on November 23 a press statement reveals. … See more.

Live Q&A with NASA Planetary Defender

Posted by in categories: asteroid/comet impacts, existential risks

NASA planetary defender Dr. Kelly Fast has a hard and fast rule: “Find asteroids before they find us.” Working in NASA’s Planetary Defense Coordination Office, Kelly is helping send the #DARTMission to test “nudging” an asteroid in space. DART, short for Double Asteroid Redirection Test, is a planetary defense-driven test of technologies for preventing an impact of Earth by a hazardous near-Earth object. DART will be the first demonstration of the kinetic impactor technique to change the motion of an asteroid in space. NOTE: the target asteroid is currently not a threat to Earth.

A Second Object Crashed into Jupiter in Just One Month (video)

Posted by in categories: asteroid/comet impacts, existential risks

According to astronomers, several asteroids with diameters more than 10 meters collide with the surface of the solar system’s largest planet every year, causing explosions visible from Earth. Previously, such collisions were registered in 1,994 2009, 2,010 2012, 2,016 2017 and 2019.

If confirmed, this will be the ninth recorded impact on Jupiter since the first in July 1,994 when Comet Shoemaker-Levy 9 shattered into several smaller pieces, sinking one after another into the giant’s gas shell, leaving dark marks on the clouds of Jupiter, some of them the size of our planet.

NASA’s ‘Armageddon’-style asteroid deflection mission takes off in November

Posted by in categories: asteroid/comet impacts, existential risks, satellites

NASA has a launch date for that most Hollywood of missions, the Double Asteroid Redirection Test, which is basically a dry run of the movie “Armageddon.” Unlike the film, this will not involve nukes, oil rigs or Aerosmith, but instead is a practical test of our ability to change the trajectory of an asteroid in a significant and predictable way.

The DART mission, managed by the Planetary Defense Coordination Office (!), involves sending a pair of satellites out to a relatively nearby pair of asteroids, known as the Didymos binary. It’s one large-ish asteroid, approximately 780 meters across — that’s Didymos proper — and a 160-meter “moonlet” in its orbit.

Planetary Defense: Physicists Propose New Way To Defend Earth Against Cosmic Impacts

Posted by in categories: asteroid/comet impacts, existential risks, physics

Is Planetary Defense PI in the Sky?

In February of 2,013 skywatchers around the world turned their attention toward asteroid 2012 DA14, a cosmic rock about 150 feet (50 meters) in diameter that was going to fly closer to Earth than the spacecraft that bring us satellite TV.

Little did they realize as they prepared for the once-in-several-decades event that another bit of celestial debris was hurtling toward Earth, with a more direct heading. On February 15 2013, the Chelyabinsk meteor, a roughly 62-foot (19 meter)-diameter asteroid exploded over the city of Chelyabinsk, Russia, as it entered Earth’s atmosphere at a shallow angle. The blast shattered windows and damaged buildings, and nearly two thousand people were hurt, though thankfully no one died.

A huge asteroid almost hit earth but NASA didn’t detect it until a day later

Posted by in categories: asteroid/comet impacts, existential risks

A giant asteroid almost hit earth on September 16 but because it came from the direction of the sun, scientists missed it.

If you heard a whooshing noise recently, you weren’t imagining it—there was indeed a gigantic asteroid that almost hit earth this month. And NASA didn’t see it coming.

A super-huge comet is hurtling through space towards solar system

Posted by in categories: asteroid/comet impacts, existential risks

Talk about comets or asteroids coming anywhere near us and mind immediately goes back to what happened to dinosaurs. It just needed a space rock to end the reign of those fearsome reptiles who dominated nearly the entire foodchain. The asteroid that killed dinosaurs was just 10 kilometres across. But now a comet larger than Mars’s moons is speeding up toward the solar system.

Bernardinelli-Bernstein comet is a mammoth! Remember Hale-Bopp? The comet that went around us in the year 1997? It was called a massive comet. And Bernardinelli-Bernstein is 10 times the mass of Hale-Bopp.

NASA Upped the Chance of Asteroid Bennu Slamming Into Earth — Putting the Odds in Perspective

Posted by in categories: asteroid/comet impacts, existential risks


Like Hitting a Bullseye With Your Eyes Closed Two statisticians put into perspective the chances of asteroid Bennu striking Earth in the next 300 years. Even Harry Stamper would probably like these odds. Recently NASA updated its forecast of the chances that the asteroid Bennu, one of the two most hazardous known objects in our solar system, will hit Earth in the next 300 years. New calculations put the odds at 1 in 1,750 a figure slightly higher than previously thought.

Evolving threat

Posted by in categories: asteroid/comet impacts, biological, biotech/medical, cyborgs, evolution, existential risks, military, nanotechnology, quantum physics

This #COVID19 is quite weird it just keeps evolving. In a weird way it is pushing evolution through our immune system. The only thing I know that is similar is like the flu or a bigger organism like cancer. Based on this information the virus just keeps evolving not dying off. Among the weird stuff it doesn’t effect cats or most animals or plants. Basically we either need a universal vaccine which is still being developed or we may need quantum radar to kill off the virus in our bodies when it comes out either that or foglet armor to not breathe it in like Ironman. I find it is just an odd virus as essentially it evolves so fast past even human beings abilities to fend it off even with suits it seems to spread so fast that it cannot be completely contained. From dogs that sniff it out it seems sorta everywhere. I know minor things like high dosages of vitamin c work with zinc and probiotics which was the first way to battle it when it didn’t become this whole pandemic because oddly enough it wasn’t a big deal in previous years because the 19th version of the virus. I know some things that kill it off are ultra violet and lysol as well as bleach. So it makes me think it is more a bioweapon where the universal vaccine would work. But oddly enough I am uncertain if it really dies off especially if it is airborne. If we can destroy the virus by reprogramming it to be sterile or innert or even for it to just kill itself off with crispr like we have done with mosquitoes to stop malaria. We can easily make new vaccines which is good but nearly every year or so there is an entirely new version. This isn’t new but it sorta is like the flu. But there are some theories that I sorta have where it seems to be near heat sources where it grows. Like my uncle who had the virus which we had him turn off electricity and also do vitamin c probiotics and zinc which did work. He ended up getting an antibody naturally this way. I personally got the vaccine and found that it does work but when the new delta version came out it did the same as the last one it sorta just randomly evolves for some reason even smells similar but oddly enough it still remains even after all the lysol. So to me it seems like a bioweapon that is self evolving which is we could use the mechanism to essentially evolve ourselves taking the components of it. If this was a nanobot swarm I would say it spreads from radio waves or something but this virus keeps spreading in odd ways like even from the sky. Which sorta makes me believe that it is sorta being manipulated maybe by a signal perhaps or it has its own program inside it. It reminds me of a Grey goo nanobot swarm that keeps evolving but the biological virus version. I mean it could actually be an exterrestial virus there was a meteorite that came around then and odd things that followed from the meteorite like dogs attacking people and cats attacking people even huge mountain lions. Which makes me think of a sorta an invasion of something. We need to maybe get the viruses input and output to find what it is going to do next. All and all seems odd because even other viruses don’t evolve or like fly or spread that fast. Ideally we should have cyborg nanobots running through Ironman in avengers endgame but so far our best better is treating it like the flu pumping out a new vaccine each year till we know a universal vaccine like using henreitta lacks immortal unlimited cell division cells like they did with polio. But till then we need to keep watching the virus as seems sorta more than it appears based on its original version.
