Selecting items for a journey to the Moon is a unique challenge, combining personal, practical, and technical considerations. As NASA progresses with its Artemis program, aiming to send astronauts back to the lunar surface, the question of what to pack becomes more than theoretical. Astronauts must consider both the strict limits of payload weight and the personal significance of the few items they can bring along.
Personal Preference Kits (PPKs) have been a tradition since the Gemini program, allowing astronauts to take along a small selection of personal items. These kits often contain items like family photos, organizational flags, and personal mementos, which serve as both a comfort and a reminder of home while in the stark lunar environment. Every astronaut traveling to the International Space Station is allotted a small volume of space for these items, a practice that is likely to continue for missions to the Moon.
When contemplating a trip beyond Earth’s atmosphere, practicality must be balanced with sentiment. The constraints of space travel mean that every gram carried to the Moon is scrutinized for its worth. Nevertheless, the items chosen hold immense personal value, offering a connection to Earth and to the individuals an astronaut holds dear, providing psychological support during the rigorous journey to our celestial neighbor.

- Core Stage: The SLS’s core stage is pivotal, holding over 730,000 gallons of super-cooled liquid hydrogen and liquid oxygen. It is the backbone of the SLS, providing structural support for the attachment of two solid rocket boosters and four RS-25 engines, which are repurposed engines from the Space Shuttle program.
Launch Site: Launches occur at the Kennedy Space Center, a historically significant site for American spaceflight, where a specialized launch platform and infrastructure support the complex needs of the SLS.
Orion Spacecraft: The SLS is designed to carry the Orion spacecraft, which will ferry astronauts to lunar orbit. Orion is equipped for long-duration deep space travel, built with life support, propulsion, and thermal protection systems.
Green Run: Prior to maiden flights, the SLS core stage undergoes comprehensive testing known as the “Green Run,” a crucial series of eight tests to validate the core stage’s design and performance, ensuring it is fit for crewed missions.
Communication and Documentation
Essential to any lunar mission is the astronauts’ ability to engage with the public and document their experiences. The equipment required for these tasks must be compact, durable, and functional in the Moon’s harsh environment.
Social Media Engagement
Astronauts are likely to use platforms such as Twitter, Instagram, and Facebook to share their journey. These three social media giants have become ubiquitous channels for real-time engagement. Astronauts can post updates, send tweets, or share images directly from the Moon’s surface. To facilitate this, they would need communication devices that are compatible with the Moon’s network infrastructure, which NASA or other space agencies provide.
- Twitter: Ideal for quick, real-time updates and engaging with followers through concise messages.
- Instagram: Perfect for sharing high-quality images and short videos, utilizing the platform’s strong visual focus.
- Facebook: Useful for more detailed posts, live streaming events, and community engagement through groups and pages.
Photography and Video Recording
For photography and video recording, the choice of camera equipment is critical. Without the proper technology, capturing crisp images and clear videos would be challenging. Cameras and recording devices must operate effectively in conditions with no atmosphere and extreme temperatures, which could range from -173°C to 127°C.
- Still Photography: The use of a camera with a high-resolution sensor and a durable body is required.
