Call it a particular supply: after six years in house, Japan’s Hayabusa2 probe is heading residence, however solely to drop off its uncommon asteroid samples earlier than beginning a brand new mission.
The fridge-sized probe, launched in December 2014, has already thrilled scientists by touchdown on and gathering materials from an asteroid some 300 million kilometres (185 million miles) from Earth.
But its work is not over but, with scientists from Japan’s house company JAXA now planning to prolong its mission for greater than a decade and focusing on two new asteroids.
Before that mission can start, Hayabusa2 wants to drop off its treasured samples from the asteroid Ryugu, “dragon palace” in Japanese.
Scientists are hoping the capsule will include round 0.1 grams of fabric that may supply clues about what the photo voltaic system was like at its start some 4.6 billion years in the past.
The samples might make clear “how matter is scattered around the solar system, why it exists on the asteroid and how it is related to Earth,” challenge supervisor Yuichi Tsuda informed reporters forward of Sunday’s drop-off.
The materials is in a capsule that may separate from Hayabusa2 whereas it’s some 220,000 kilometres above Earth after which plummet into the southern Australian desert.
They have been collected throughout two essential phases of the mission final 12 months.
In the primary, Hayabusa2 touched down on Ryugu to gather mud earlier than firing an “impactor” to fire up pristine materials from beneath the floor. Months later, it touched down to gather further samples.
“We may be able to get substances that will give us clues to the birth of a planet and the origin of life… I’m very interested to see the substances,” mission supervisor Makoto Yoshikawa informed reporters.
Protected from daylight and radiation contained in the capsule, the samples will likely be collected, processed, then flown to Japan.
Half the fabric will likely be shared between JAXA, US house company NASA and different worldwide organisations, and the remainder stored for future examine as advances are made in analytic know-how.
Two new asteroid targets
After dropping off its samples, Hayabusa2 will full a collection of orbits across the solar for round six years, recording knowledge on mud in interplanetary house and observing exoplanets.
It will then strategy the primary of its goal asteroids in July 2026.
The probe will not get that shut to the asteroid named 2001 CC21, however scientists hope it is going to be ready to {photograph} it because it completes a “high speed swing-by”.
Getting so shut might additionally assist develop information about how to shield Earth in opposition to asteroid impression.
Hayabusa2 will then head in the direction of its important goal, 1998 KY26, a ball-shaped asteroid with a diameter of simply 30 metres. When the probe arrives on the asteroid in July 2031, it is going to be roughly 300 million kilometres from Earth.
And the goal poses vital new challenges, not least as a result of it’s spinning quickly, rotating on its axis about each 10 minutes.
Hayabusa2 will observe and {photograph} the asteroid, however it’s unlikely to land and gather samples, because it in all probability will not have sufficient gasoline to return them to Earth.
Still, simply making it to the asteroid will likely be a feat, mentioned Seiichiro Watanabe, a Hayabusa2 probe challenge scientist and professor of planetary science at Nagoya University.
“It’s like an athlete who scored two tries at a Rugby World Cup game attempting to compete in the Olympics, 10 years after switching over to figure skating,” he informed reporters.
“We had never expected that the Hayabusa2 would carry out another mission… but it’s a scientifically meaningful and fascinating plan.”
The mission extension comes with dangers, together with that Hayabusa2’s tools will degrade in deep house, however it additionally provides a uncommon, comparatively cost-effective approach to proceed analysis.
The probe is the successor to JAXA’s first asteroid explorer “Hayabusa”, which implies falcon in Japanese.
That probe introduced again mud samples from a smaller, potato-shaped asteroid in 2010 after a seven-year odyssey, and was hailed as a scientific triumph.
