China’s Tianwen-2 asteroid sample return mission is set to launch this month, May 2025, en route to the asteroid Kamoʻoalewa (2016 HO3). The country could join the United States and Japan, whose space agencies have both successfully retrieved a sample from an asteroid to study back on Earth. Several space missions have flown by asteroids before and gotten a peek at their compositions, but bringing a sample back to Earth is even more helpful for scientists.

These objects come from space missions designed to transport physical extraterrestrial samples from outer space to Earth. Because of this similarity to meteoroids in entry, we often refer to these sample return capsules, or SRCs, as "artificial meteors." This sample return provided our teams with a unique opportunity to measure the sound waves and other phenomena that objects from space produce as they speed through the Earth's atmosphere.

By Elizabeth A. Silber, Senior R&D Scientist, Physics, Sandia National Laboratories Earth is constantly bombarded by fragments of rock and ice, also known as meteoroids, from outer space. Most of the meteoroids are as tiny as grains of sand and small pebbles, and they completely burn up high in the atmosphere. You can see meteoroids larger than about a golf ball when they light up as meteors or shooting stars on a dark, clear night.
