NASA will attempt to deflect an asteroid, impact to happen next fall

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

NASA calls it the “Double Asteroid Redirection Test,” or DART for short, and the mission involves NASA launching a spacecraft that will rocket towards the Didymos binary asteroid and collide with it. NASA wants to test if the impact of the spacecraft colliding with the asteroid will be enough to alter its course. It should be noted that the asteroid doesn’t currently pose any threat to Earth and that NASA is purely conducting this mission for research purposes.

According to NASA’s latest update on DART, the spacecraft recently received solar arrays that will be a core component to getting the spacecraft all the way to the Didmos asteroid system. The spacecraft will travel for ten months to reach the asteroid system and will launch aboard SpaceX’s Falcon 9 rocket this November. When the spacecraft collides with the asteroid, it will be traveling at around 15,000 mph, and NASA will have Earth-based telescopes aimed at the asteroid for clear observation.

NASA forecasts an Empire State-sized asteroid could hit Earth

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

O,.o…zap it o.o


Scientists at NASA have adjusted their forecast of an Empire State Building-sized asteroid it predicts could potentially smash into the planet.

The chances of the large rock hitting the Earth have increased. In a press conference Wednesday, NASA said there was a 1-in-1,750 chance the asteroid, Bennu, could smash into the Earth between now and 2300. It’s a higher chance than previously predicted at 1 in 2,700 chances.

Asteroid impact chances increased

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

A study by NASA has used precision-tracking data from the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft to more accurately plot the route of potentially hazardous asteroid Bennu from now until the year 2300.

The agency’s new data, published this week in Icarus, has significantly reduced the uncertainties related to its future orbit, and improved scientists’ ability to determine the total impact probability and predict the orbits of other asteroids.

“NASA’s Planetary Defense mission is to find and monitor asteroids and comets that can come near Earth and may pose a hazard to our planet,” said Kelly Fast, program manager for the Near-Earth Object Observations Program at NASA Headquarters in Washington. “We carry out this endeavour through continuing astronomical surveys that collect data to discover previously unknown objects and refine our orbital models for them. The OSIRIS-REx mission has provided an extraordinary opportunity to refine and test these models, helping us better predict where Bennu will be when it makes its close approach to Earth more than a century from now.”

NASA Mission Reveals Probability of Hazardous Asteroid Paths Up to Nearly 300 Years

Scientists find origin of asteroid that killed the dinosaurs

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

Astronomers believe that they have discovered the origin of the asteroid that wiped out the dinosaurs.

The six mile-wide asteroid which struck the Earth 66 million years ago and ended the 180 million year-long reign of the dinosaurs, was the cause of what is known as a Chicxulub events. It landed in what is now the Yucatan peninsula in Mexico and formed the Chicxulub crater.

Scientists had examined the remains of the ancient rock through the samples on the Earth and within drill cores, which revealed that the debris came from a carbonaceous chondrite class of meteorites – some of the most pristine material in the entire solar system.

Origin of dinosaur-ending asteroid possibly found. And it’s dark

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

Scientists figured out what slammed into Earth and killed the dinosaurs 66 million years ago: a giant dark primitive asteroid from the outer reaches of the solar system’s main asteroid belt.

SpaceTime Series 24 Episode 91
*Astronomers zero in on source of the impactor that wiped out the dinosaurs.
A new study claims the impactor believed to have wiped out and 75 percent of all life on Earth 66 million years ago including all the non-avian dinosaurs — likely came from the outer half of the main asteroid belt between Mars and Jupiter.
*Producing matter out of pure energy.
Scientists have directly converted pure light energy into matter in a single process for the first time.
The findings reported in the journal Physical Review Letters involved the creation of Electrons and their antimatter counter parts positrons — by colliding quantum packets of photons – light particles.
*Discovery of a galactic stream of galaxy clusters.
Astronomers have discovered a never-before-seen galaxy cluster with a black hole at its centre, travelling at high speed along an intergalactic road of matter.
*Solar Orbiter and BepiColombo making space history with double flyby of Venus.
As we go to air tonight the European Space Agency is making space history with two of its space craft6 undertaking almost simultaneous flybys of the planet Venus.

NBD, There’s Just a Massive Asteroid Hurtling Past Earth This Month

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

Should you be worried about the massive space rock that could, theoretically, spell disaster if it were to make landfall on terra firma? No, you shouldn’t. But that doesn’t mean you should ignore it either.

The asteroid, called 2016 AJ193, is just under a mile wide and moving at a speed of 58538 miles per hour, according to EarthSky. Its closest encounter with Earth will occur on August 23 at 11:10 a.m. ET, and experts note that anyone trying to spot the asteroid in the wild will have the best chance of doing so before sunrise. If you’re trying to catch a glimpse of it, you’ll have to use a telescope.

Despite the “potentially hazardous” label designated by NASA, EarthSky is quick to allay any fears of impending apocalypse (at least from this particular asteroid) because it won’t hit Earth.

Asteroid the size of the Great Pyramid of Giza just flew (safely)

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

😀


An asteroid about as long as the Great Pyramid of Giza is tall made a “close” approach with Earth on Sunday (July 25), according to NASA calculations.

There is no worry that the space rock poses any threat to Earth, but NASA monitors such rocks to both learn more about the early solar system — asteroids are rocky fragments from that time — and because if their orbits were to change, the asteroid could pose a future risk to Earth.
