Europe and Japan's BepiColombo spacecraft, which launched in 2018, will fly by Earth on 10 April and use our planet's gravity to swing towards the inner solar system. Learn more about this mission and why we study Mercury.
Europe and Japan’s first Mercury mission will study how the planet formed.
The innermost planet is a contradictory mystery.
The Planetary Society is celebrating the 50th anniversary of Apollo 13, which launched on 11 April 1970. Disaster struck on 13 April, prompting the crew's infamous "Houston, we've had a problem" call for help. Learn what happened, and how NASA got the astronauts home safely on 17 April.
Apollo 13 was the 3rd attempt to land humans on the Moon and the 1st to fail. Fifty-six hours into the mission, an explosion forced the crew to abort their Moon landing and take shelter in the Lunar Module. The crew ultimately returned to Earth safely.
