 SHAMS's mission patch | |
SHAMS (Arabic: شمس, meaning: Sun) (or SHMS[3], also referred to as Space Weather CubeSat-1 (SWC-1)[4]) is a 12U CubeSat developed by Saudi Arabia's Space Agency as a rideshare payload on the Artemis II mission.[5] The probe's primary mission is to study the effects of space weather in the cislunar environment outside of Earth's magnetic field.
Background
In July 2024, Saudi Arabia and the United States signed a framework agreement to promote space cooperation between the two countries.[6] In part due to this agreement, a Saudi rideshare mission was selected for Artemis II during Donald Trump's state visit to Saudi Arabia on May 14, 2025.[6] SHAMS is also meant to demonstrate Saudi abilities to manufacturer and operate satellites, as part of Vision 2030.[6][7] The Satellite was manufactured by the National Industrial Development and Logistics Program, a Saudi program specifically designed to increase its aerospace industry capacity.[7]
Mission
SWC-1 · Earth
SHAMS will collect data on the impact of solar activity on the Earth's magnetosphere to help enhance techniques to keep humans safe in space and improve communication abilities.[6][7][8] The CubeSat is designed to measure radiation, solar X-rays, charged particles, and magnetic fields in high Earth orbit.[9][10][11]
On Saturday, April 3, the SSA would announce that the probes name was Shams despite all NASA documentation naming it the SWC-1.[8][5] In the same press release the SSA gave more information on the probe's mission, outlining it's elliptical high-earth-orbit as being between 500 km to 70,000 km and that the space weather studies will help develop the reliability of communications, aviation, and navigation technologies.[5]
