Hera Mission – Europe Launches to Investigate Asteroid Hit by NASA

In an age where space exploration is more focused on planetary defense, humanity has taken a significant step toward safeguarding Earth. On October 7, 2024, the European Space Agency (ESA) launched the Hera mission, marking the next phase in the study of asteroids. Hera will investigate the binary asteroid system Didymos and its smaller moon Dimorphos, which NASA’s DART mission impacted in 2022. The goal is to collect critical data on planetary defense strategies that may one day protect Earth from rogue space rocks.

NASA’s DART (Double Asteroid Redirect Mission) struck Dimorphos to test if an asteroid’s orbit could be altered. The mission succeeded, reducing Dimorphos’ orbit around Didymos by 33 minutes. Now, Hera will build on DART’s success by conducting a more detailed study of the asteroid’s changes, surface characteristics, and impact crater.

Mission Overview

The Hera mission was launched aboard a SpaceX Falcon 9 rocket from Cape Canaveral at 10:52 a.m. EDT. Unlike most SpaceX launches, the first stage of the Falcon 9 did not return to Earth for reuse. To ensure Hera had enough fuel to reach its target, the booster burned up its reserves entirely, leading to a planned disposal in the ocean. This particular Falcon 9 booster had been used in 23 previous missions, including Starlink satellite launches, NASA astronaut flights, and rideshare missions.

Hera’s journey will take it through the solar system, passing by Mars in 2025 for a gravity assist before heading to its final destination – the binary asteroid system of Didymos and Dimorphos.

Why Dimorphos?

The choice of Dimorphos as the mission’s target is strategic. The DART impact on the asteroid in 2022 was the first attempt by humanity to intentionally change the orbit of a celestial body. DART’s success demonstrated the potential of using kinetic impactors to deflect an asteroid’s path, offering hope that we could one day protect Earth from a catastrophic collision.

– Alan Fitzsimmons, Hera Science Team Board Member

Hera will examine whether the DART impact did more than alter Dimorphos’ orbit. It will investigate whether the impact changed Dimorphos’ surface composition or even its shape. Additionally, the mission will measure the size and depth of the crater left by DART’s collision, further refining models for future asteroid deflection strategies.

International Planetary Defense

One of the most exciting aspects of Hera is its contribution to the growing field of planetary defense. Earth is constantly under the threat of potential impacts from asteroids, and understanding how to deflect or destroy these bodies is vital to our survival. Hera is part of a larger, international effort to protect our planet. As ESA Director General Josef Aschbacher put it:

“Defending our planet from space threats involves countries from all around the world. I am very pleased about this cooperation. The Hera spacecraft is a project by ESA, which stands for the European Space Agency. This spacecraft is leading Europe’s efforts to protect Earth from potential dangers from space.”

While the NASA DART mission proved that an asteroid could be deflected, Hera will refine our understanding of how such impacts work and how effective they can be.

What Will Hera Do?

Once Hera arrives at Dimorphos in 2026, it will begin its mission of measuring the impact crater created by DART. Scientists are eager to learn how much material was ejected during the collision and how deep the crater penetrated into the asteroid’s surface.

Mission Objectives

Crater Measurement: Hera will assess the depth and diameter of the crater caused by DART.
Orbital Analysis: Confirm the orbital changes caused by DART’s impact.
Surface Examination: Analyze the composition of surface minerals and look for any shape alterations in Dimorphos.
