The crew of Artemis II used commercially available memory cards to store images captured during their journey around the Moon, highlighting an unusual overlap between space exploration hardware and consumer technology. The mission marked a significant milestone, carrying astronauts farther from Earth than any previous crewed flight.
The images, including views of Earth from deep space, were stored on CFexpress Type B Iridium memory cards produced by ProGrade Digital. The same 400GB version used during the mission is currently available for purchase, reflecting how off-the-shelf components are increasingly integrated into space systems, according to TechRadar.
The cards were selected as part of a collaboration between NASA and ProGrade Digital under a Space Act agreement. They were tested against multiple commercial alternatives and qualified for use in demanding environments similar to those encountered during space missions.
Engineers subjected the storage devices to prolonged exposure to extreme conditions, including temperature fluctuations and radiation-like stress scenarios, to ensure reliability. The cards were integrated into the Handheld Universal Lunar Camera system, designed for use in current and future Artemis missions.
Jeremy Myers, a hardware lead on the project, noted that capturing images on the lunar surface presents unique technical challenges, particularly for storage media. Reliable performance is essential to ensure that high-resolution images and video can be recorded without data loss.
The memory cards offer read speeds of up to 3550 MB per second and sustained write speeds of around 850 MB per second, enabling them to handle large image files and high-resolution video formats such as 4K and 8K. These specifications are comparable to those required by professional photographers and videographers on Earth.
The same class of storage hardware is expected to be used in future missions, including Artemis III, where astronauts are planned to land on the lunar surface. The use of commercial components reflects a broader trend in the space industry toward leveraging existing technologies to reduce development time and costs.
The integration of widely available hardware into a crewed lunar mission illustrates how consumer-grade technology is increasingly meeting the reliability standards required for space exploration.
