First Hayabusa2 talk to feature in SPIE conference

11 Dec 2020

Successful mission to be described in free SPIE Astronomical Telescopes + Instrumentation Digital Forum (14-18 December).

As part of the opening plenary session at next week’s SPIE Astronomical Telescopes + Instrumentation Digital Forum, Hitoshi Kuninaka, of the Japan Aerospace Exploration Agency, will be discussing and responding to audience questions about the successful return of the Hayabusa2 capsule from its asteroid-sample mission, a second-time-in-history-success that marks exciting and innovating advances for the astronomical-instrumentation community.

In addition, Kuninaka may reveal initial information regarding what potential treasures the capsule's sample container holds.

"I'm so excited to hear more about this mission," commented SPIE Astronomical Telescopes + Instrumentation Chair Alison Peck. "The level of precision needed to pull this off — for the navigation as well as the engineering that went into the spacecraft itself — is just mind-blowing. This really ushers in a new era of 'in-person' study of the composition of these solar system bodies."

Free, online, and public welcome

SPIE Astronomical Telescopes + Instrumentation Digital Forum, showcasing and sharing the latest in space- and ground-based telescopes and related engineering, runs 14-18 December. The interactive plenary session — as well as the rest of the digital forum — will be accessible online, and registration to the event is free and open to the public. The plenary session is scheduled for 12 to 2 PM Pacific Time on 14 December.

This is the second successful Hayabusa attempt to bring asteroid material to Earth: in 2010, the original Hayabusa capsule brought back samples from the asteroid Itokawa, a pioneering success which allowed scientists to learn Itokawa's age and geologic history.

The latest sample materials (which arrived back on earth, in South Australia, on December 5th) stem from an 18-month rendezvous that Hayabusa2 — launched in 2014 — had with Ryugu, a carbonaceous, or C-type, asteroid, a class of asteroid believed to contain organic materials and hydrates.

During its year-and-a-half meet-up, Hayabusa2 observed Ryugu remotely as well as collecting material and data from the astral body's surface and subsurface. The Hayabusa missions are historical firsts, the only successful sample-return missions so far.

"We think that asteroids, comets, and cosmic dust played important roles in terms of transferring material inside the solar system, and Hayabusa and Hayabusa2 have inspired us to explore the above hypothesis," says Kuninaka. "If the asteroid Ryugu is indeed confirmed to be shown to be carbon rich, there is a strong possibility of resource utilization for the international human space exploration."

"They have done a fantastic job in completing all actions of this mission without major failures," notes SPIE Astronomical Telescopes + Instrumentation Chair Satoru Iguchi. "A lot of technically challenging goals were successfully achieved, including touchdown on the asteroid Ryugu, the collection of samples, and a successful return to Earth. Just as exciting, an investigation of the samples should offer us a deeper understanding of the origin of life."

• Interested parties can register for the event on the SPIE Astronomical Telescopes + Instrumentation Digital Forum website. To support this vital community during these challenging times, SPIE has transitioned this event into a safe and accessible, free Digital Forum that will run 14-18 December, 2020.
