2020 will see a veritable Mars invasion as several spacecraft, including three landers, head to the red planet. NASA will launch its Mars 2020 rover, which will stash rock samples that will be returned to Earth in a future mission and will also feature a small, detachable helicopter drone. China will send its first lander to Mars, Huoxing-1, which will deploy a small rover. A Russian spacecraft will deliver a European Space Agency (ESA) rover to the red planet — if issues with the landing parachute can be resolved. And the United Arab Emirates will send an orbiter, in the first Mars mission by an Arab country.
Closer to home, China is planning to send the Chang’e-5 sample-return mission to the Moon. And elsewhere in the Solar System, Japan’s Hayabusa2 mission is due to return samples of the asteroid Ryugu to Earth, and NASA’s OSIRIS-REx will bite off a chunk of its own asteroid, Bennu.
