LOS ANGELES, May 14 (Xinhua) -- NASA and the Saudi Space Agency have signed an agreement for a Saudi Arabia CubeSat to be launched aboard NASA's upcoming Artemis II test flight, the U.S. space agency said Tuesday.

The agreement was reached during U.S. President Donald Trump's trip to Saudi Arabia.

The Saudi Space Agency's CubeSat will measure aspects of space weather at a range of distances from Earth and deploy in high Earth orbit from a spacecraft adapter on NASA's Space Launch System rocket after the Orion spacecraft is safely flying on its own with its crew of four astronauts, according to NASA.

CubeSats are about the size of a shoebox and contain technology demonstrations or investigations with the potential to gather information to improve understanding of the space environment.

The Saudi Space Agency CubeSats will collect data on space radiation, solar X-rays, solar energetic particles, and magnetic fields, according to NASA.

NASA's Artemis II test flight is scheduled for April 2026. ■
