NASA’s Lucy spacecraft successfully completed its second encounter with an asteroid recently, this time with the asteroid named Donaldjohanson. During the rendezvous on April 20, Lucy’s Long-Range Reconnaissance Imager (L’LORRI) captured images of the elongated asteroid from a distance of about 600 miles, revealing its intricate geology. According to Hal Levison, the principal investigator of Lucy at the Southwest Research Institute, the images provide valuable insights into the asteroid’s formation and the processes that shaped our Solar System.
In a statement released by NASA on April 21, Levison mentioned, “Studying the complex structures in detail will offer significant information about the origins and development of the planets in our Solar System.”
The detailed observations of Donaldjohanson validate earlier findings by astronomers, particularly the asteroid’s 10-day brightness fluctuation cycle. The images reveal an elongated asteroid believed to have formed from the collision of two smaller bodies. Researchers also noted the distinct neck shape that connects the two lobes of Donaldjohanson.
Surprisingly, the asteroid’s size exceeded initial estimates, measuring approximately 5 miles in length and 2 miles in width. Donaldjohanson was even wider than the field of view of Lucy, and it will take some time for the remaining data to be transmitted back to Earth. Additional information will be extracted from data collected by the L’Ralph color imager, infrared spectrometer, and the L’TES thermal infrared spectrometer.
This recent encounter with Donaldjohanson marks Lucy’s second asteroid rendezvous, following its close pass by Dinkinesh (also known as “Dinky”) and its satellite, Selam, 16 months ago. Donaldjohanson is the second of 10 asteroids that Lucy is slated to study during its 12-year mission.
Tom Statler, a NASA program scientist for the Lucy mission, expressed excitement about the upcoming exploration of the Trojan asteroids, stating, “The potential to gain new insights into the history of our solar system when Lucy reaches the Trojan asteroids is enormous.” Lucy will now traverse the solar system’s main asteroid belt for the remainder of 2025 as it heads towards its primary target, the Jupiter Trojan asteroid Eurybates. The final flyby is scheduled for August 2027.

The following is a unique, detailed article about the benefits of meditation:
Meditation has been practiced for thousands of years and has been shown to have numerous benefits for both the mind and body. While some may view meditation as simply sitting quietly and clearing the mind, it actually involves a variety of techniques that can help improve overall well-being.
One of the key benefits of meditation is its ability to reduce stress and anxiety. By focusing on the present moment and letting go of worries about the past or future, meditation can help calm the mind and create a sense of inner peace. This can have a profound impact on mental health, as chronic stress and anxiety have been linked to a variety of health issues, including heart disease and depression.
In addition to its mental health benefits, meditation can also have a positive impact on physical health. Studies have shown that regular meditation practice can lower blood pressure, improve immune function, and even reduce inflammation in the body. This can lead to a reduced risk of chronic diseases and an overall improvement in physical well-being.
Furthermore, meditation has been shown to improve focus and concentration. By training the mind to stay present and focused on a single point of attention, meditation can help improve cognitive function and enhance productivity. This can be particularly beneficial for those who struggle with distractions or have difficulty staying focused on tasks.
Overall, meditation is a powerful tool for improving both mental and physical health. By incorporating meditation into your daily routine, you can experience a greater sense of calm, reduced stress levels, improved physical health, and enhanced focus and concentration. With so many benefits to be gained, it’s worth giving meditation a try and seeing how it can positively impact your life.
