An important mission for Hayabusa2, continuing its adventure after return.

Even after delivering its samples back to Earth, Hayabusa2's journey wasn't over. Surprisingly, it is heading back into the depths of space, targeting a new asteroid named 'Torifune.' There is a plan for it to pass by Torifune on July 5, 2026. The episode also introduces the unexpected reason why it continues its journey despite the long mission duration: the probe's airframe and engines still have plenty of life left.

Taking on the challenge of approaching a rapidly rotating celestial body in an extended mission.

This mission isn't just about passing by. Torifune, the destination for Hayabusa2, is an asteroid that spins at incredible speeds. Performing an encounter that feels like 'saying goodbye in one second' with such a high-speed target requires precise, advanced calculations. In the middle of the episode, the hosts discuss a specific technology that will be put to the test during the Torifune flyby.

An experiment in Planetary Defense to protect the future of Earth.

Part of the purpose of this journey includes a technical demonstration of 'Planetary Defense,' designed to protect our planet from celestial bodies that might collide with Earth in the future. The experience gained from this extended mission will likely play a significant role in upcoming space exploration. The episode is packed with inspiring stories about Hayabusa2 as it takes on missions for the future. Be sure to check out the full episode to hear the rest of the story.
