OSIRIS-APEX Captures Breathtaking Earth and Moon Images During Flyby
In a stunning display of celestial photography, NASA’s OSIRIS-APEX spacecraft has transmitted remarkable images of Earth and the Moon as it swung past our planet. The flyby, a critical maneuver in the probe’s journey to the asteroid Apophis, provided a unique opportunity to capture these breathtaking views. These images aren’t just visually striking; they serve as a vital check on the spacecraft’s instruments and navigation systems, ensuring everything is functioning optimally for the mission ahead. Notebookcheck first reported on the captivating imagery.
The OSIRIS-APEX mission, originally known as OSIRIS-REx, successfully delivered a sample from asteroid Bennu to Earth in September 2023. Following this monumental achievement, NASA repurposed the spacecraft for a new mission: a rendezvous with asteroid Apophis. This new trajectory required a carefully calculated gravitational assist – a “slingshot” effect – using Earth’s gravity. The recent flyby was a crucial part of this maneuver, bringing the spacecraft closer to its ultimate destination. NASA Science details the intricacies of this maneuver.
The OSIRIS-APEX Mission: A Second Life for a Pioneering Spacecraft
The transformation of OSIRIS-REx into OSIRIS-APEX represents a remarkable feat of engineering and mission planning. Instead of being retired after its successful sample return, the spacecraft was given a new lease on life, tasked with studying asteroid Apophis. This decision not only maximizes the return on investment for the original mission but also provides a unique opportunity to study an asteroid that will make a close approach to Earth in 2029.
Apophis, a near-Earth asteroid approximately 370 meters in diameter, initially caused concern due to early calculations suggesting a potential impact with Earth. However, subsequent observations have ruled out an impact for at least the next century. Nevertheless, studying Apophis is crucial for understanding the behavior of near-Earth objects and developing strategies for planetary defense.

Capturing the ‘Pale Blue Dot’ and Beyond
The images captured during the Earth flyby are more than just aesthetically pleasing. They serve as a critical calibration exercise for the spacecraft’s MapCam instrument, which will be used to study Apophis. The team at the University of Arizona, responsible for operating the MapCam, used the Earth and Moon as known targets to verify the instrument’s performance. The University of Arizona News highlights the importance of this calibration process.
These images also offer a poignant reminder of our place in the cosmos, echoing Carl Sagan’s famous “Pale Blue Dot” description of Earth. Seeing our planet from such a distance provides a unique perspective on its fragility and the importance of protecting it. What impact do you think these images will have on public perception of space exploration? And how might this mission contribute to our understanding of planetary defense?
