Are near-Earth objects DANGEROUS? Know what NASA says about scary comets, asteroids
Asteroid and Earth
1/5 Earth has objects near it, which sometimes get attracted towards the planet because of its gravitational pull. Of course, not every near-Earth object manages to reach the surface of the planet. The object needs to be large enough to survive its fiery journey through the atmosphere of the Earth. (Pixabay)

2/5 What is a near-Earth object? Asteroids or comets that can pass within 30 million miles or 50 million kilometers of Earth's orbit are known as near-Earth objects or NEO. According to NASA, "A near-Earth object (NEO) is an asteroid or comet whose orbit brings it within a zone approximately 121 million miles (195 million kilometers) from the Sun, meaning that it can pass within about 30 million miles (50 million kilometers) of Earth’s orbit."

3/5 NASA further informed that the vast majority of NEOs that enter Earth’s atmosphere disintegrate before reaching the surface (and more than 100 tons of dust particles disintegrate in Earth’s atmosphere daily). Those NEOs that are larger than around 98 to 164 feet (30 to 50 meters) in size could cause widespread damage in and around their impact sites. Apart from NEOs, there is another category that NASA uses. These are the potentially hazardous objects (PHO). These are near-Earth objects whose orbit brings them within 4.7 million miles (7.5 million km) of Earth’s orbit, or is greater than 500 feet (140 meters) in size. (Pixabay)
4/5 The highest risk of impact for a known asteroid is a 1 in 714 chance of impact by an asteroid designated 2009 FD in 2185. This means that the possibility that it could impact then is less than 0.2 percent. NASA said, "One asteroid that NASA is studying up close, called Bennu, has a 1/2700 chance of impacting Earth between 2175 and 2195. The OSIRIS-REx spacecraft will complete a 2-year investigation of Bennu before plucking a sample of asteroid material off its surface and delivering it back to Earth." (Pixabay)
5/5 How can we prevent an asteroid from hitting Earth? Currently, an asteroid impact is the only natural disaster that NASA 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.

After numerous delays, NASA has finally launched its Artemis I mission yesterday, November 16 from the Kennedy Space Center. NASA's first attempt to launch the Orion spacecraft resulted in failure due to a malfunction in the core stage of one of the four RS-25 engines of the Space Launch System (SLS). Additionally, engineers also detected a “leak” in the inner tank of the upper stage. There was a visible build-up of ice and frost and a trail of vapour could be seen which led to NASA scrubbing the launch.

After yesterday's successful launch, the Orion spacecraft captured a breathtaking image of Earth while leaving the planet's atmosphere. NASA shared the image on the Orion spacecraft's twitter page. The space agency wrote, “We look back at the Earth from 58,000 miles away. Find out more about the cameras Orion uses to capture this flight.”

According to NASA, there are 24 cameras aboard the Orion spacecraft and the Space Launch System (SLS), with 8 cameras on the Orion spacecraft, and the rest aboard the SLS. Four cameras are attached to the Orion spacecraft's solar arrays which enable the spacecraft to capture selfies with Earth or any other object in the background.

David Melendrez, imagery integration lead for the Orion Program at NASA's Johnson Space Center in Houston said in a NASA blog, “Each of Orion's four solar array wings has a commercial off-the-shelf camera mounted at the tip that has been highly modified for use in space, providing a view of the spacecraft exterior.”

What is Artemis I Mission?

According to NASA, Artemis I is the first uncrewed flight test of the Space Launch System rocket and the Orion spacecraft. The Artemis Programme is NASA's first attempt to send a manned mission to the Moon since the Apollo missions in 1972.

The Orion spacecraft, although unmanned, carries 3 manikins called Zohar, Helga and Campos to space as human stand-ins for various tests and studies. They are retrofitted with a vast number of sensors to conduct tests regarding the spaceflight.

The Orion capsule is carrying various objects like Snoopy dog toys which will fly as a zero-gravity indicator in the capsule. A new version of Alexa called Callisto created by Lockheed Martin, Amazon, and Cisco will also be aboard the spacecraft.
