Experience Easter Sunday with NASA’s Lucy Probe: A Historic Flyby of Asteroid Donaldjohanson!

Easter Sunday will be a thrilling day for space enthusiasts and scientists alike. NASA’s Lucy spacecraft is set to make a close pass by the asteroid Donaldjohanson at 1:51 p.m. EDT on April 20, 2025. Launched in 2021, Lucy is on a remarkable 12-year mission to explore the Trojan asteroids near Jupiter. These asteroids are believed to hold crucial secrets about the early solar system and the building blocks of life.

Before reaching the Trojans, Lucy is practicing her skills. On November 1, 2023, she successfully flew by another asteroid called Dinkinesh. Now, she will approach Donaldjohanson from about 620 miles (1,000 kilometers) away, allowing her to test her scientific instruments.

Among these tools are:

• L’Ralph: A color camera and infrared spectrometer.
• L’LLORI: A high-resolution imaging device.
• L’TES: A thermal emission spectrometer that will help understand the asteroid’s composition.

Phil Christensen, a professor at Arizona State University, designed L’TES. He explained that this flyby is crucial for gathering data as if Donaldjohanson were one of the Trojan asteroids. Understanding the makeup of these celestial bodies can provide insights into how our solar system formed.

Interestingly, Lucy’s name honors the 3-million-year-old fossil skeleton discovered by paleoanthropologist Donald Johanson. That discovery was pivotal in shaping our understanding of human origins. In a recent interview, Johanson reflected on the Lucy mission and mentioned that if a secondary asteroid is detected during the upcoming flyby, he would ponder over a fitting name.

The excitement surrounding Lucy’s mission is mirrored in the public’s growing interest in space exploration. According to a recent survey, about 70% of Americans have expressed a keen interest in learning more about asteroids and space missions. This trend reflects a larger societal shift towards science and a curiosity about our universe.

In the world of social media, hashtags related to Lucy and asteroid research are trending, with many users sharing their thoughts and excitement about these celestial bodies. As Lucy continues her journey, we can’t help but wonder what discoveries await us.
