China's Tianwen-2 is Off to Collect an Asteroid Sample
China's Tianwen-2 mission blasted off on Wednesday, embarking on an epic 8-year journey that will help to unlock the secrets of an asteroid and a comet before delivering the precious cargo back to Earth. The spacecraft will first hunt down Kamoʻoalewa (asteroid 2016 HO3) which it will study for a year, extracting samples from its surface. After returning the sample to Earth, Tianwen-2 will head back out into the Solar System taking another 7 years to intercept the main belt comet 311P/Pan-STARRS. It will undertake a flyby study of this object that has never been studied before.
