TOKYO—A Japanese space probe named after a falcon arrived at an asteroid 186.41 million miles from Earth on Wednesday after a three-and-a half year journey on a mission to seek the origins of life.
The Hayabusa 2 blasted off in December 2014 for the asteroid Ryugu on a pioneering mission to take samples that scientists hope will help reveal how life began. Its round-trip mission is set to take six years.
“Everything has gone as planned,” a spokesman for the Japan Aerospace Exploration Agency (JAXA) told a news conference. “The probe has arrived at the asteroid.”
Hayabusa 2, named for the peregrine falcon, will spend the next few months orbiting about 12.4 miles above the asteroid and mapping its surface before landing. It will then use small explosives to blast a crater on the surface and collect the resulting debris.
Asteroid Ryugu is photographed by the ONC-T, which is on Hayabusa 2 probe after a journey of around 1.99 billion miles since launch, in outer space 173.98 million miles from the Earth, on June 24, 2018, at around 00:01 JST, in this handout photo released by Japan Aerospace Exploration Agency (JAXA).

Television footage showed the control room erupting in applause as the probe’s safe arrival was confirmed, with some researchers standing and grinning as they shook hands.
“We’re mostly relieved, but now there’s tension as to whether the main mission will go well,” one official said.
Should all go according to plan, Hayabusa 2 is expected to spend around 18 months near the asteroid and return to Earth with samples at the end of 2020, the year Tokyo hosts the Summer Olympic Games.
The first Hayabusa probe was unable to collect as much material as hoped but still made history by being the first probe to bring back samples from a different asteroid.
Its seven-year mission ended in 2010 when it blazed a trail over Australia before slamming into the desert.
Success with Hayabusa 2 would help Japan’s space program move beyond a checkered past that included a 2016 accident in which the first of three planned military communication satellites was crushed during a flight from Japan to Europe’s space port in French Guiana.
The first such satellite eventually blasted successfully into space in January 2017.
