Introduction of Upcoming Missions
The European Space Agency's Hera mission and NASA's Europa Clipper mission are highly anticipated launches that are set to enhance our understanding of asteroids and ocean moons. Hera is particularly significant as it follows up on NASA's Double Asteroid Redirection Test (DART) mission, where a spacecraft successfully impacted the moonlet Dimorphos to change its trajectory. Scheduled to launch on October 7, 2024, Hera aims to investigate the results of the DART impact, using advanced instruments to analyze the crater and measure Dimorphos' mass. Both missions symbolize a thrilling 'Launchtober' and an important step in planetary defense and exploration during World Space Week.
Details of the Hera Mission
Hera's mission objectives include measuring the mass of Dimorphos, studying the impact crater formed by the DART mission, and exploring the overall structure of the Didymos-Dimorphos system. The spacecraft is equipped with high-resolution imaging, laser, and radio mapping devices, ensuring a comprehensive examination of the asteroid moon. Additionally, Hera will deploy two CubeSats, Milani and Juventas, which will enhance the research capabilities by mapping the asteroid's interior and conducting surface composition analysis, respectively. This investigation is expected to provide valuable insights into the effectiveness of the kinetic impactor method for deflecting asteroids and improve our planetary defense strategies.
Lessons from Previous Missions
The Hera mission is built on the legacy of previous explorations, particularly the Rosetta mission, which provided profound insights into comets and asteroids over a long operational period. The operational principles and methodologies used in Rosetta are being adapted for Hera, allowing for thorough characterization of the target asteroids. As noted, several lessons learned, particularly about interactions with the small bodies in space, will guide the operations around Didymos and Dimorphos. Through this mission, scientists aim to enhance our understanding of binary asteroid systems, which represent a significant proportion of near-Earth asteroids.
Impact on Planetary Defense
Planetary defense missions like Hera and DART are crucial as they represent humanity's proactive steps towards mitigating potential asteroid threats. Though statistically the risk of an asteroid impact is low, the implications of such an event are dire, warranting the development of methods to track and deflect near-Earth objects. By conducting detailed studies and simulations, the Hera mission will help refine impact models, significantly contributing to our readiness for any future threats from space. The collaborative nature of these missions between international space agencies further emphasizes the importance of global cooperation in addressing planetary defense challenges.
Public Engagement and Space Advocacy
The upcoming launches provide an excellent opportunity for public engagement and advocacy for space exploration. Initiatives like NASA's 'Runway to Jupiter' challenge encourage creativity and community participation, allowing fans to express their excitement about the Europa Clipper through themed outfits and accessories. This not only spreads awareness about upcoming missions but also fosters a sense of community among space enthusiasts. Such engagement is vital in advocating for continued investment and interest in planetary science, ensuring that the dialogue around space exploration remains vibrant and inclusive.
We look forward to the Oct. 7 launch of the European Space Agency's Hera spacecraft with Michael Küppers, project scientist for the mission. Then Ambre Trujillo, our digital community manager at The Planetary Society, lets you know how to celebrate Europa Clipper by joining NASA's Runway to Jupiter style challenge. We'll close out with Bruce Betts, our chief scientist, and a discussion of the potential future meteor shower caused by the DART impact in What's Up.
