Exploring the Future of Asteroid and Moon Missions: Trends and Innovations
The Rise of Asteroid Deflection Technology
The success of missions like NASA’s DART, which impacted the Dimorphos asteroid in 2022, and ESA’s Hera mission, which launched on October 7, marks a significant milestone in planetary defence. These missions have laid the groundwork for developing asteroid deflection as a repeatable and reliable technique. As we delve deeper into the cosmos, the ability to alter the trajectory of asteroids, whether to prevent collisions with Earth or to utilize their resources, will become increasingly important.
Gravitational Assist: Fuel Saving and Quantifiable Fuel Efficiency
One of the most intriguing aspects of the Hera mission is its use of gravitational assist—a trajectory correction burn that provides further insight into Hera’s sense of humanity. By coming as close as 3,107 miles (5,000 kilometers) to Mars, the planet’s gravity shifted Hera’s trajectory towards its final destination, the Didymos binary asteroid. Never in a single fly by is this much fuel saved in a single plane by Hera’s team of flight navigators and dynamical experts.
Did you know?
Gravitational assists can significantly alter the trajectory of a spacecraft, often extending its mission range and increasing our reach into space.
Mars Moons: Deimos and Phobos
Surveying Deimos: A Stepping Stone for Future Missions
During the flyby, Hera was able to image Deimos, Mars’s smaller and more mysterious moon, from a distance of 236.2 mi. To offer some perspective, Mars is further than our moon compared by a factor of 2.5, believed to be a tidally locked formation. Deimos might be a leftover of a giant impact on Mars or a captured asteroid or from Mars.
| Deimos | Phobos | |
|---|---|---|
| Discovery Year | 1877 | 1877 |
| Diameter (km) | 12.6 | 22.2 |
| Distance from Mars (km) | 23,460 | 9,377 |
| Orbital Period (hrs) | 30.3 | 7.7 |
| Possibly Origin | Captured asteroid/large impact | Captured asteroid |
Martian Moons eXploration (MMX) Mission
The data collected by Hera during its encounter with Deimos will be invaluable for the upcoming Martian Moons eXploration (MMX) mission, led by JAXA in collaboration with NASA, CNES, and ESA. MMX will not only collect detailed measurements of both Martian moons but also land on Phobos to collect a sample and return it to Earth for analysis, which will help improve our understanding of Mars and its moons.
The Technological Advancements of Hera
Imaging Technologies
Hera is equipped with a trio of advanced instruments that promise to revolutionize our understanding of asteroids and moons. These include:
- Asteroid Framing Camera (AFC):
The AFC, a 1020 x 1020 black and white, has proven invaluable for both navigation and scientific investigation, acquiring images in visible light - Hyperscout H Hyperspectral Imager:
This advanced imager observes in a range of colors beyond the limits of human eyesight, covering 25 visible and near-infrared spectral bands. This capability will help characterize the mineral makeup of asteroids and moons. - Thermal Infrared Imager (TIR):
Supplied by JAXA, the TIR images at mid-infrared wavelengths to chart surface temperatures and reveal physical properties such as roughness, particle size distribution, and porosity.
Collaborative Observations with Mars Express
Hera also performed joint observations of Deimos with ESA’s Mars Express, which has been in orbit around Mars for over two decades. This collaboration underscores the importance of international cooperation in space exploration.
