NASA’s OSIRIS-REx spacecraft is embarking on a new mission to study the asteroid Apophis, which is set to make a close pass by Earth on April 13, 2029. Affectionately named after the Egyptian god of Chaos, Apophis has captured scientists’ curiosity due to its unique serpent-like shape.
This exciting opportunity will not only provide valuable insights into the composition of the asteroid but also offer a stunning spectacle for stargazers around the world. The naked eye visibility of Apophis’ flyby is expected in regions including Asia, the Indian Ocean, Australia, most of Africa and Europe, and even parts of the Pacific Ocean.
In preparation for this celestial event, NASA has renamed the spacecraft OSIRIS-APEX (Origins, Spectral Interpretation, Resource Identification, and Security – Apophis Explorer). The mission, estimated to cost around $200 million, aims to bring us closer to understanding the mysteries surrounding this “S-type” asteroid, comprising silicate and nickel-iron materials.
To unravel the secrets locked within Apophis, OSIRIS-APEX will approach within a range of 25 meters of the asteroid’s surface. By studying the surface changes resulting from the interaction with Earth’s gravity, researchers hope to gain valuable insights into the nature of these celestial bodies.
Apart from its scientific significance, Apophis’ close encounter with our planet presents an opportunity for NASA to further explore planetary defense strategies. The alterations to Apophis’ orbit and the lengthening of its 30.6-hour day brought about by its proximity to Earth provide valuable data for such research.
Fortunately, recent modeling and radar observations have ruled out the possibility of a collision between Apophis and Earth. This reassures us that our planet will remain safe from any potential harm caused by this cosmic dance.
Once the flyby is complete, OSIRIS-APEX will continue its mission near Apophis for an additional 18 months. This phase will allow scientists to study and analyze the changes brought about by the asteroid’s proximity to our planet, providing further insights into the fascinating world of asteroids.
As the countdown to the Apophis’ close approach begins, both scientists and enthusiasts eagerly await the wealth of knowledge and beauty that this celestial encounter will bring. Stay tuned for more updates and be ready to witness this extraordinary event at the heart of the universe.
