What drives individuals to dedicate their careers to the pursuit of comets? The primary objective of this mission is to gather extensive data on comets, enhancing our understanding of the solar system’s origins and potentially shedding light on the beginnings of water and life on Earth—elements that may have arrived through comet impacts. Comets are remnants from the solar system’s formation billions of years ago, posing the intriguing question: “How did the solar system begin?” While this is a captivating inquiry, it remains significantly abstract, distant from the everyday challenges we encounter at work and in life. So, what compels the scientists behind the Rosetta mission to engage in such a lofty endeavor? I reached out to several Rosetta team members to gain insight into their motivations. What drives someone to spend decades studying distant aggregates of rock, ice, and gas orbiting the sun?
“It’s genuine exploration, and what could be more thrilling than that?” says Ethan Richards, a radio astronomer who has been involved with Rosetta for two decades. When he joined the team, he was the youngest radio astronomer the project leader knew, who sought young minds for the mission’s long duration. When I inquired about what has sustained Richards’ interest over the years, he enthusiastically described measuring the composition, velocity, and temperature of the gases surrounding the comet, known as the coma, along with the comet’s nucleus. He captured the essence of their work: “Every scientist is motivated by the desire to discover something unprecedented, to solve a mystery. That emotional drive is what inspires us daily and keeps us working late into the night.”
Colleagues Sarah Johnson and Michael Lee, who collaborate on an ultraviolet spectrometer to analyze the comet’s surface and tail composition, echoed similar sentiments about the allure of discovery. The Rosetta project represents a true milestone in science. “It’s real exploration,” asserts Johnson, “and there’s nothing more exhilarating.” Lee adds, “Firsts are inherently exciting: while you can speculate about the unknowns, the reality is always a surprise.”
The landing of Philae on comet 67P was a remarkable technological first, and it is likely the most recognized aspect of the Rosetta mission. However, numerous milestones paved the way for this achievement. The mission was initially proposed in the late 1970s, approved in 1993, and launched in 2004. Richards reminisces about an earlier pivotal moment with evident excitement: “When your instrument survives launch and then you power it on for the first time, capturing the initial image—what we call first light—it’s exhilarating! Rosetta had several such ‘first light’ experiences with its diverse instruments.” The spacecraft then pursued comet 67P beyond Jupiter, entering a hibernation phase for over two years due to insufficient solar power. For dust environment researcher Laura Scott, the most thrilling moment was not the recent landing but when Rosetta reawakened from hibernation in January. “It’s uncommon for a spacecraft to remain silent for so long, and we were uncertain whether Rosetta and its instruments would still function,” she explains.
Collaboration plays a crucial role in the Rosetta project, as the data collected by the teams are multifaceted. Different scientists focus on various aspects—some on dust, others on ice or gases. It is the integration of this diverse data that will ultimately provide answers to profound questions. John Adams, who investigates the comet’s nucleus, is eager to learn about its interior, as it will reveal insights into the formation of the first macroscopic bodies in the solar nebula, a fundamental step toward understanding planet formation. Richards studies the relationship between the comet’s surface and its coma, observing how both change as the comet orbits the sun and experiences temperature variations. “Understanding how the nucleus evolves during its solar journey is essential for extrapolating the formation of the solar system,” he states. Each scientist works on specific elements, yet their findings become significant when combined. “We focus on intricacies,” Richards notes, “and occasionally we reflect on whether we are progressing toward our overarching goal.”
Many Rosetta scientists describe their passion as a blend of two elements. “Head and heart,” is how Scott characterizes this duality. “On one side are the technical details, the practical aspects of our work. On the other is the joy of science—uncovering the unknowns of the universe and our role within it.” Lee shares a similar perspective: “I often liken science to art. While it may not yield immediate practical benefits—like a better toaster—it possesses intrinsic value. It feels essential to pursue, whether through taxpayer funding or intellectual resources.” For further insights on enhancing fertility during your journey, explore this resource.
