In 2018, NASA invited people worldwide to send their names to the Sun. More than 1.1 million did and their names are still travelling aboard Parker Solar Probe

In 2018, NASA invited people around the world to send their names on a historic journey towards the Sun aboard a spacecraft designed to fly through its outer atmosphere.

The campaign attracted 1,137,202 confirmed submissions. NASA digitally stored the names on a small memory card installed on the Parker Solar Probe before its launch, making them a permanent part of one of the agency’s most ambitious solar missions.
