    1/5 DART mission is NASA’s $330 million first step to protect the planet against asteroids against potential impact. The aim of the mission was to smash a spacecraft into the Dimorphos asteroid to deflect it away from its path. This test will help scientists gain greater knowledge as to what happens when a craft is crashed against a space rock. (AP)

    2/5 After months of anticipation, this test took place during today’s early hours when the DART spacecraft sacrificed itself by colliding with Dimorphos asteroid at 7:14 p.m. EDT. According to NASA, Dimorphos is an asteroid moonlet just 530 feet in width and orbits a larger asteroid called Didymos, nearly 5 times its size. (NASA)

    3/5 NASA DART test was captured by a small companion satellite which followed the DART spacecraft to the target asteroid Dimorphos. The spacecraft’s camera is a cubeSAT called LICIACube (Light Italian CubeSat for Imaging Asteroids). The cubeSAT is made up of two key components, LUKE (LICIACube Unit Key Explorer) and LEIA (LICIACube Explorer Imaging for Asteroid), both of which capture key data from the collision. (Bloomberg)

    4/5 European Space Agency’s Hera spacecraft will fly to the asteroid to survey the aftermath of impact and gather information such as the size of impact crater, the mass of the asteroid and its make-up and internal structure using its CubeSAT satellite to conduct a radar probe of the asteroid after the collision (ESA)

    Now that NASA has successfully conducted its first planetary defense test against rogue asteroids which hurtle towards Earth and generate fear, the world can breathe a sigh of relief. However, NASA is not done yet. NASA and other agencies will study the DART data over the next few weeks to determine the details of the asteroid deflection which will provide greater knowledge as to what happens when a craft is crashed against a space rock. But until then, we're still not safe from asteroids, and one just flew past Earth today.

    Asteroid 2022 SZ

    NASA has warned that a huge asteroid, named Asteroid 2022 SZ has just flown past the planet. The asteroid made its closest approach to Earth during the early hours of today, September 29, at a distance of 5.2 million kilometers. It flew past the planet at a staggering speed of 25200 kilometers per hour.

    According to the-sky.org, Asteroid 2022 SZ belongs to the Apollo group of asteroids. The asteroid takes 463 days to complete one orbit around the Sun, during which its maximum distance from the Sun is 221 million kilometers and nearest distance is 130 million kilometers.

    These past months have seen a sudden increase in the frequency of asteroid flybys.

    Tech involved in the DART mission

    Didymos Reconnaissance and Asteroid Camera for Optical navigation (DRACO) along with Small-body Maneuvering Autonomous Real Time Navigation (SMART Nav) algorithms aboard the DART spacecraft allowed it to distinguish between the larger Didymos and its target Dimorphos, striking the asteroid with precision accuracy, according to NASA.

    NASA's first planetary defense attempt was captured through cameras of a small companion satellite named cubeSAT LICIACube (Light Italian CubeSat for Imaging Asteroids). The cubeSAT is made up of two key components, LUKE (LICIACube Unit Key Explorer) and LEIA (LICIACube Explorer Imaging for Asteroid), both of which capture key data from the collision.
