The Saudi Space Agency announced the successful launch of its new satellite, Shams, and established contact with it as part of the Artemis II mission, marking the Kingdom’s emergence as both the leading Arab partner in the program and the first to deploy a dedicated national mission to study space weather.
The satellite represents a milestone in Saudi innovation. Developed domestically by Saudi engineers, Shams has evolved from a national ambition into a scientific platform designed to monitor solar activity and radiation and their effects on Earth, with implications for safeguarding global communications and navigation systems.
The Artemis program, led by NASA in partnership with dozens of countries, aims to return humans to lunar orbit for the first time in more than 50 years, paving the way for future missions to Mars. Saudi Arabia joined the Artemis Accords in 2022 alongside more than 60 nations to help establish a framework for space exploration and strengthen its role in the sector.
The Artemis II mission will carry four astronauts on the first crewed flight to orbit the Moon aboard the Orion spacecraft, launched by the Space Launch System (SLS), the most powerful rocket ever operated. Shams is included as one of the mission’s scientific payloads.
The satellite will operate in a highly elliptical orbit (HEO), ranging from approximately 500 km to 70,000 km above Earth. This trajectory enables broad monitoring of solar and radiation activity, advancing space weather research and supporting critical applications.
Space laboratory to tackle radiation and solar activity challenges
Shams is designed to study space weather through four scientific areas: space radiation, solar X-rays, Earth’s magnetic field and high-energy solar particles. It will also collect data to support the development of protection technologies for future human spaceflight and improve understanding of solar particle behavior and magnetic fields.
The mission is expected to enhance the reliability and sustainability of key sectors such as communications, aviation and navigation by providing data that improves operational readiness and strengthens the security of critical infrastructure.
The Saudi Space Agency said the project aims to boost scientific research, develop future solutions and support a knowledge-based economy through the localization of advanced technologies, in line with Saudi Vision 2030. It also seeks to reinforce Saudi Arabia’s global standing in the space sector and empower national talent in space science and technology.
Data from Shams is expected to improve early warning systems for solar storms that can disrupt internet services, telecommunications and navigation signals. The findings could also help protect power grids and energy infrastructure from severe solar activity that can cause outages or damage.
By improving monitoring of radiation and solar winds, the mission may contribute to safer air travel and future crewed missions to the Moon and Mars, while opening new avenues in medicine, energy and science.
