(CNN) – A new space telescope can detect potentially dangerous asteroids and comets heading for Earth, one step closer to reality.
The NearEarth Object Surveyor Space Telescope, or NEO Surveyor, has been approved by NASA to enter the design phase. The 20-foot-long (6-meter-long) infrared telescope will help astronomers find asteroids and comets within 30 million miles (48 million kilometers) of Earth’s orbit, thereby strengthening planetary defenses.
The launch of the mission is currently scheduled for the first half of 2026.
“NEO Surveyor will have the ability to rapidly accelerate NASA’s discovery of asteroids and comets that can cause damage to Earth, and Mike Kelly, a scientist from the The Near-Earth Object Surveyor program at NASA headquarters said in a statement that it points to 90% of asteroids 140 meters (459 feet) or larger were discovered within ten years of launch.

Wednesday is International Asteroid Day, which commemorates the largest recorded asteroid impact on Earth, while paying attention to the truly dangerous Earth where asteroids can collide with Earth.
In 1908, a powerful asteroid struck the Podkamenaya Tunguska River in the remote Siberian forest of Russia. The incident razed trees and destroyed forests in a radius of 770 square miles, equivalent to three-quarters of the area of ​​Rhode Island in the United States. In a city 40 miles away, the impact knocked people to the ground.
This explains why the astronomers and the Asteroid Day team want people to realize this. Detecting NEO or NEO threats that can cause serious damage is the primary focus of NASA and other space organizations around the world.
In 2010, NASA completed its goal of discovering 90% of near-Earth objects over 1,000 meters (3,280 feet) in size. The agency was subsequently ordered by the National Aeronautics and Space Administration Act of 2005 to search for 90% of NEOs greater than 140 meters (459 feet).
So far, NASA has discovered 40% of the celestial bodies within this range.
“Every night astronomers around the world try to use ground-based optical telescopes to discover new near-Earth objects, describe their shape and size, and confirm that they will not pose a threat to us,” said Kelly Fast, project manager at the POT. it said in a statement.
“Those telescopes can only search for near-Earth objects in the night sky. Near-Earth astrometers will allow continuous observation day and night, especially in areas where dangerous near-Earth objects can be found, and will accelerate the process to achieve the objectives of Congress. ”

The ability to discover and characterize potentially dangerous near-Earth objects also enables astronomers to track these objects. Currently, the threat of near-Earth objects impacting Earth in the next century is not known. However, unknown NEOs can cause unpredictable effects, such as the Chelyabinsk event in Russia.
In 2013, an asteroid entered Earth’s atmosphere over Chelyabinsk, Russia. It exploded in the air, releasing 20 to 30 times more energy than the first atomic bomb, generating greater brightness than the sun, radiating heat, damaging more than 7,000 buildings and injuring more than 1,000 people. The shock wave broke a window 58 miles away. It was not discovered because the asteroid came from the same direction and trajectory as the sun.
These meteorites landed on Earth after a 22 million-year journey.

NEO surveyors will use infrared sensors to help astronomers find these objects. The direction of the sun. It is impossible to use ground-based observatories.
“By searching for NEOs closer to the direction of the sun, NEOs will help astronomers discover possible impact hazards that may approach the Earth from the sky during the day,” University of Arizona’s lead researcher of NEOs and professor Amy at the university Meenzer said the Arizona Lunar and Planetary Laboratory said in a statement.
“We think there are approximately 25,000 NEOs large enough to destroy areas like Southern California,” Mainzer said. “Once they exceed 137 meters in diameter, they can cause severe regional damage. We want to find these, and as many asteroids as possible. “The

NEO surveyors can detect them in The heat emitted in infrared light is used to search for asteroids. This information can help astronomers detect the position, movement and size of near-Earth objects. The telescope will orbit away from the moon. This position will allow you to scan the sky and focus closer to the sun You can find the asteroid

“Asteroids and comets close to the Earth are heated by the sun and emit heat that can be captured by the Near-Earth Astrometer mission,” Mainzer said. “Even asteroids as dark as coals cannot avoid our infrared eyes. With NEO Surveyor, we hope to discover potentially dangerous near-Earth objects years or decades after a possible impact. Provide as many as possible Time to develop mitigation measures so that we can exclude them. ”
Asteroid deflection
If there is sufficient warning, near-Earth objects may be deflected.
