Default This asteroid is one of the most likely to hit Earth. Here’s what it means for our future.

This asteroid is one of the most likely to hit Earth. Here’s what it means for our future.

New ultraprecise measurements show that the asteroid Bennu has a higher chance than thought of impacting our planet sometime in the next 300 years, NASA says.


AUGUST 11, 2021

For hundreds of millions of years, a top-shaped rubble pile called Bennu has orbited the sun in relative isolation. The asteroid, about a third of a mile wide at its equator, poses no immediate threat to our planet. But hundreds of years from now, there is a small chance that Bennu could slam into Earth.

In a new study published in the scientific journal Icarus, scientists used data from NASA’s OSIRIS-REx spacecraft to make a precise calculation of Bennu’s orbit and its future proximity to our home planet. The researchers then analyzed the impact hazard between now and the year 2300. The study finds a 1-in-1,750 chance of a future collision over the next three centuries—a slightly higher probability than previously estimated.

September 24, 2182 is the earliest date scientists have worked out that Bennu could impact Earth, about a 1 in 2,700 chance. Hopefully in the next 150 years technology will advance to the point where we can prevent such a collision, either by firing nuclear missiles or directed-energy weapons to destroy the asteroid or nudge it out of the way.

Default Double Asteroid Redirection Test (DART) Mission

DART Gets Its Wings: Spacecraft Integrated with Innovative Solar Array Technology and Camera
Quote:
Perched atop a stand in the middle of a high-ceilinged clean room, DART is beginning to look like the intrepid spacecraft that will aim itself directly into an asteroid next fall. With the addition of its compact Roll-Out Solar Arrays (ROSA)​ coiled into two gold cylinders that flank the sides of the spacecraft, and its less visible but still integral​ imager, the Didymos Reconnaissance and Asteroid Camera for Optical (DRACO) navigation tucked safely beneath its panels, the spacecraft is close to fully integrated.

This mix of current and new technologies, some of which it will demonstrate for the first time, will see DART through its 10​-month journey toward its asteroid target.

The recently installed Roll-Out Solar Arrays (ROSA) and Didymos Reconnaissance and Asteroid Camera for Optical (DRACO) navigation are two critical technologies that will enable the DART spacecraft to navigate through space and effectively reach the Didymos asteroid system.

NASA's DART, the Double Asteroid Redirection Test, is a carefully planned demonstration that will help determine if kinetic impactor technology—flying a spacecraft directly into a small Solar System body at speeds of about 15,000 miles per hour with the intention of changing its course—can serve as a reliable method of asteroid deflection in the event that such a hazard ever heads for the Earth. NASA is constantly monitoring the skies and has already identified nearly 40% of potentially hazardous asteroids larger than 140 meters (459 feet) in size, none of which are slated to impact our planet, including the binary system selected for this first-ever deflection test.​

Shitlibs have been terrified for some time of the all-White future portrayed in 'The Jetsons',(!?!), actually becoming reality...

If the jews succeed in genociding Whites out of existence, then jews and Earth deserve to be wiped out by an asteroid collision.

The DART mission just launched.


I was able to see the launch from my front yard, but it was too dim to record it.

I think NASA already has the technology that allows a spacecraft to get next to an asteroid and move it out of an orbit that could impact the earth. I remember watching a TED
talk a couple of years ago where a scientist discussed this.
They could also hit it with a tactical nuke and blowed it up real good, as John Candy and Joe Flaherty used to say on Farm Film Report. Remember SCTV.

Blowing up an asteroid without deflecting it would do no good. It would simply hit the earth in many pieces instead of one.

I was joking about blowing it up. On the SCTV sketch Farm Film Report they were always talking about blowing up stuff real good.

I've heard that as well but I don't understand the argument. Seems like if the pieces were made small enough (we can use multi stage nukes of arbitrarily high yield to achieve this) they wouldn't pose a threat since they'd vaporize in the atmosphere before hitting the surface of the Earth.

From NASA's website:

Quote:
How can we prevent an asteroid from hitting Earth?
Currently, an asteroid impact is the only natural disaster we might be able to prevent. There are a few methods that NASA is studying to deflect an asteroid on a course to impact Earth. One of these techniques is called a gravity tractor—it involves a spacecraft that would rendezvous with an asteroid (but not land on its surface) and maintain its relative, optimal position to use the mutual gravity attraction between the satellite and the asteroid to slowly alter the course of the asteroid. A gravity tractor spacecraft could even enhance its own gravitational attraction by first plucking a boulder off the surface of the asteroid to add to its own mass.

A kinetic impactor is currently the simplest and most technologically mature method available to defend against asteroids. In this technique, a spacecraft is launched that simply slams itself into the asteroid at several km per second speed. Scientists will test the kinetic impact technique by the Double-Asteroid Redirect Test mission (DART) on an asteroid system called Didymos in 2022. DART’s target is a binary asteroid system where one football-stadium-sized asteroid (Didymos B) is orbiting a half-mile-wide asteroid (Didymos A). NASA’s goal is to send the car-sized DART spacecraft slamming into Didymos B at 25,000 kilometers per hour (16,000 miles per hour) to determine by how much the impact can shift the orbit of Didymos B around Didymos A. After all, we’d only need to nudge an asteroid’s orbit enough to make it either seven minutes early or seven minutes late in its intersection with Earth’s orbit. It takes seven minutes for the Earth to travel the distance of its diameter, so if an asteroid arrives seven minutes early or late—it’ll miss us completely.

Nuclear explosive device methods are considered the last resort when it comes to NEO deflection, though they may be the most effective for preventing a cataclysmic event. When warning time is short or the asteroid is large, deploying a nuclear device is the most effective option. A standoff detonation is the method with the most controllability and predictability for using a nuclear device to deflect an asteroid. This method works by detonating a nuclear device at a few hundred meters above the surface of the asteroid. The energy from the device is primarily in the form of X-rays, which near instantly strike the surface of the asteroid. The material in the top layers of the asteroid is super-heated and vaporized by this radiation, causing a blow-off of material from the surface. The momentum push from the vaporized and blown off surface material imparts momentum to the rest of the asteroid and pushes it onto a new trajectory. Therefore, it is not the force from the explosion itself that moves the asteroid but rather the force of the radiated energy onto the surface of the asteroid.
So the goal with the nuke is to impart momentum to push the asteroid into a new trajectory, not blast it into smaller bits. It seems like it could work, but I've also heard folks say it's not a viable solution.

When you watch The Jetsons today, you can't help thinking that in 1962 most White people didn't know at all what was in store for them. Anti-natalist feminism (2nd-wave feminism), non-White mass immigration, and race-mixing propaganda had not begun yet.

https://vnnforum.com/showthread.php?t=563990

All the recent sci-fi movies and series deceptively conceal the current White Genocide by portraying a mostly White future which will not happen. How could the Whites be a minority everywhere in 2050 and a majority in 2300 or 2400? That's nonsensical and very misleading. The message is clear and can be summarized as follow: White people, don't be afraid! Your world is not threatened. Don't fight. Just have fun. Trust us, Goyim.
