The aim of NASA to stop the asteroid Bennu from destroying Earth and its status as a ticking time bomb : Report

NASA is taking every precaution to avoid the impact of the asteroid Bennu, which is considered to be one of the two most dangerous asteroids in our solar system. NASA has projected that the asteroid Bennu, which is named after an Egyptian legendary bird and is linked to the Sun, creation, and rebirth, will collide with Earth.

This undated image provided by NASA shows the asteroid Bennu seen from the OSIRIS-REx spacecraft. On Sunday, Sept. 24, 2023, the OSIRIS-REx spacecraft will fly by Earth and drop off what is expected to be at least a cupful of rubble it grabbed from Bennu, closing out a seven-year quest.

The space research centre launched OSIRIS-REx, an asteroid investigation and sample return mission, in 2016 to gather an asteroid sample and investigate its origin in an effort to save the Earth and, ideally, avert the problem.

Bennu, which is 510 meters broad and taller than the Empire State Building, might strike Earth and release 1,2000 megatons of energy, which is 24 times more energy than the most potent nuclear weapon ever created.

According to calculations, the collision would take place between the years 2100 and 2200, with the afternoon of September 24, 2182, having the highest likelihood of having an impact. According to NASA, the likelihood of the impact occurring by the year 2300 is 1 in 1,750 or 0.05%.

NASA has classified Bennu as a “potentially hazardous asteroid” that might approach Earth within 4.65 million miles, despite the fact that it has been given a less likely status for the time being. Bennu continues to be one of the two most dangerous known asteroids in our solar system, along with another asteroid known as 1950 DA, despite the extremely low likelihood that it will strike Earth.

Over 4.5 billion years ago, during the first 10 million years of the solar system’s history, Bennu was formed.

In order to gather a sample, the spacecraft OSIRIS-REx was deployed to the asteroid Bennu in 2016. The OSIRIS-REx spacecraft released the nine ounces of samples of the asteroid that is planned to touch down in the Utah desert today, on September 24, 2023, Sunday.

The capsule’s release while passing the earth at a distance of 63,000 miles and its parachuting down onto the military’s Utah Test and Training Range four hours later mark the end of a seven-year mission. The samples, according to NASA Administrator Bill Nelson, could “help us better understand the types of asteroids that could threaten Earth” and shed information “on the earliest history of our solar system.”

The samples will be transported by helicopter to a temporary clean room, where they will wait until Monday when they will be flown to the NASA Johnson Space Center laboratory in Houston. To know more about this mission, click here.

Amy Simon, a NASA scientist, remarked, “This sample return is really historic.”

Since the Apollo moon rocks were carried back to Earth, “this is going to be the biggest sample” that we have brought.

On October 11, 2023, NASA intends to hold a news conference to present the study’s findings.
