NASA’s OSIRIS-REx spacecraft has been relaunched to embark on a groundbreaking mission to study the infamous asteroid Apophis, which is set to approach Earth’s orbit. Scheduled to pass within 32,000 kilometers of our planet’s surface on April 13, 2029, Apophis has long piqued the curiosity of scientists due to its association with darkness and disorder, earning its name from the Egyptian god of Chaos.
Now, with the revamped spacecraft aptly named OSIRIS-APEX, NASA aims to extract vital information from Apophis, with a particular focus on understanding how the asteroid’s surface changes in response to Earth’s gravity. This ambitious mission, estimated to cost $200 million, will allow scientists to glean valuable insights into planetary defense—a top priority for the organization.
Apophis, classified as an “S-type” asteroid composed of silicate and nickel-iron materials, presents a unique opportunity for NASA to closely examine and study its composition. By closely observing this celestial body, scientists hope to gain valuable insights into the mechanisms governing asteroids and their potential impact on Earth.
Prior to the latest modeling and recent observations, concerns had been raised over a potential collision between Apophis and Earth. However, these worries have now been laid to rest, as updated data has conclusively ruled out the possibility of such an event. This reassurance provides NASA and researchers worldwide the chance to study Apophis and its interaction with Earth with a renewed focus.
After its passage, the OSIRIS-APEX will continue its mission for an additional 18 months, operating near Apophis to closely monitor any subtle changes caused by its proximity to Earth. These observations will enable scientists to enhance their understanding of the dynamics of asteroids and provide key insights into the broader field of planetary science.
NASA’s decision to relaunch the OSIRIS-REx spacecraft for the OSIRIS-APEX mission underscores the organization’s dedication to exploring and unraveling the mysteries surrounding our cosmic neighborhood. By unraveling the secrets of Apophis, NASA is taking great strides in expanding our knowledge of asteroids, their composition, and their potential impact on our planet.
