Laser Starship will stop Asteroidea’s?

I’m sure you have heard about the life-threatening encounters the Earth has every year. Luckily, most of the encounters don’t impact the lives of average humans. How long will your luck hold out??? The next video shows how useful the SpaceX Starship could be if or after it reaches orbit regularly. America’s NEW Space Laser Weapon that shouldn’t be so new? I start the above video mid-way, when…

China's observatories capture images of falling near-Earth asteroid

Several observatories in China have captured rare images of a falling near-Earth asteroid, formally designated as 2024 XA1.

The images, along with the observation results of foreign observatories on the asteroid, mark the 11th successful early warning of an asteroid impacting Earth, and the fourth such prediction of 2024, according to China Science Daily on Friday.

The asteroid has an estimated diameter of between 75 centimeters and one meter. It was first discovered by a University of Arizona telescope at 5:55 a.m. (UTC) on December 3, the report said.

China played a crucial role in monitoring the event due to its strategic geographic location.

The Lijiang branch of the Yunnan Observatories under the Chinese Academy of Sciences (CAS) detected the asteroid during the time from 3:10 p.m. to 3:30 p.m. (UTC) on December 3 through its Lijiang 2.4-meter telescope, said Zhang Xiliang, a researcher at the Lijiang observatory.

At 4:15 p.m. (UTC) on December 3, the asteroid entered Earth's atmosphere over eastern Siberia and ignited, creating a bright fireball. The time between when the asteroid was first detected and its fall to Earth was less than 12 hours.

Sci-Fi 5: A Close Call with US19720810 - August 10, 1972

The "great daylight fireball" was a hunk of space rock that came dangerously close to the Earth on August 10, 1972.

Every day is Asteroid Day at NASA

It’s International Asteroid Day, and today we’re talking about everything asteroids! Although there are no known threats for the next 100 years, our Planetary Defense experts are constantly finding, tracking, and monitoring near-Earth objects to protect our home planet.

Asteroids are rocky remnants from the beginning of our solar system, and as of today, 26,110 near-Earth asteroids have been discovered!

So how do we spot these near-Earth objects? Let’s watch and see:

In addition to tracking and monitoring asteroids, we are also launching several missions to study these rocky relics. By studying asteroids, we can better understand the formation of our solar system. Here are some exciting missions you can look forward to:

OSIRIS-REx: Returning a Sample from Asteroid Bennu

Last year, our OSIRIS-REx mission successfully captured a sample of asteroid Bennu, a 4.5-billion-year-old asteroid the size of the empire state building.

Currently, OSISRIS-REx is making its long journey home carrying this sample as it returns to Earth in 2023.

Psyche: A Journey to a Metal World

Our Psyche mission will journey to a unique metal asteroid orbiting the Sun between Jupiter and Mars.

What makes the asteroid Psyche unique is that it appears to be the exposed nickel-iron core of an early planet, one of the building blocks of our solar system. Deep within rocky, terrestrial planets - including Earth - scientists infer the presence of metallic cores, but these lie unreachably far below the planets' rocky mantles and crusts. Because we cannot see or measure Earth's core directly, Psyche offers a unique window into the violent history of collisions and accretion that created terrestrial planets.

Lucy: Studying the Trojan Asteroids

Launching this year, our Lucy mission will be the first mission to study the Trojans, a group of asteroids that share Jupiter’s orbit around the Sun. Time capsules from the birth of our Solar System more than 4 billion years ago, the swarms of Trojan asteroids associated with Jupiter are thought to be remnants of the primordial material that formed the outer planets.

The mission takes its name from the fossilized human ancestor (called “Lucy” by her discoverers) whose skeleton provided unique insight into humanity's evolution. Likewise, the Lucy mission will revolutionize our knowledge of planetary origins and the formation of the solar system.

DART: Double Asteroid Redirection Test

Launching this year, our DART mission is a planetary defense driven test of technologies and will be the first demonstration of a technique to change the motion of an asteroid in space.

The destination of this mission is the small asteroid Dimorphos, which orbits slowly around its larger companion Didymos. Dimorphos is referred to as a moonlet since it orbits a larger asteroid.

The DART spacecraft will achieve the kinetic impact deflection by deliberately crashing itself into the moonlet. The collision will change the speed of the moonlet in its orbit around the main body by a fraction of one percent, but this will change the orbital period of the moonlet by several minutes - enough to be observed and measured using telescopes on Earth.

At NASA, every day is asteroid day, as we have missions exploring these time capsules of our solar system and surveying the sky daily to find potential hazards. We, along with our partners are watching the skies 24/7/365, so rest assured! We're always looking up.

Don’t Look Up? 🤫☄️ A rare phenomenon happens tonight! “A large stony asteroid will safely pass Earth on January 18, 2022. Its estimated size is around 3,280 feet (about 1 km or .6 of a mile), around 2 1/2 times the height of the Empire State Building.  As you can see from this asteroid’s label – (7482) 1994 PC1 – we’ve known about it since 1994. It is classified as a Potentially Hazardous Asteroid due to its size and relatively close flybys of our planet. An asteroid of this size strikes Earth approximately every 600,000 years.” Near-Earth asteroid 1994 PC1 (~1 km wide) is very well known and has been studied for decades by our #PlanetaryDefense experts. Rest assured, 1994 PC1 will safely fly past our planet 1.2 million miles away next Tues., Jan. 18.

#Stargazers will be part of an exciting #celestial moment as an #asteroid will pass by #Earth on September 6. Asteroid (465824) 2010 FR is between 120-270 metres long and could be bigger than the #Pyramid of #Giza in Egypt. The asteroid will be 7.5 million kilometres from us but the National Aeronautics and Space Administration’s (#Nasa’s) Asteroid Watch has debunked theories that it might be close enough to cause significant damage. “Our #PlanetaryDefense experts are not worried about asteroid 2010 FR and you shouldn’t be either because it has zero chance of hitting Earth. Earth globe #americas It will safely pass by our #planet on Sept. 6 more than 4.6 million miles away—that’s more than 19 times the distance of our #Moon!” Asteroid Watch tweeted. The virtual #telescope project initiative also said on their website that despite its size, the asteroid will not be able to cause any damage and people will be safe.
