Infographic of a seven-step process to investigate suspected space-pathogen exposure, with side panels on investigator needs and why speed and accuracy matter, plus lab and space imagery.

HOW WOULD A SUSPECTED SPACE-PATHOGEN EXPOSURE BE INVESTIGATED?

Infographic titled detailing mission stages, safeguards, Mars-specific caution, facility procedures, and prevention of contamination or release risks.

HOW IS AN ASTEROID OR MARS SAMPLE RETURNED SAFELY?

Infographic timeline of planetary protection from 1960s Apollo lunar quarantine to future Mars sample-return missions, with changes in science and biosafety and reasons for protecting other worlds, Earth, and research.

HOW HAS PLANETARY PROTECTION CHANGED SINCE APOLLO?

Infographic titled explaining barriers, six necessary conditions, why most scenarios fail, safeguards, terrestrial scientific concerns, and a bottom-line assessment that a true alien pandemic is highly unlikely.

COULD AN ALIEN PANDEMIC REALLY HAPPEN?

Infographic on protecting spacecraft from biological contamination via clean assembly, sterilization methods, testing, operational controls, mission-specific rules, and protection-versus-engineering tradeoffs.

HOW ARE SPACECRAFT PROTECTED FROM BIOLOGICAL CONTAMINATION?

Infographic explaining multi-layer biological containment with concentric barriers from sample container to emergency procedures, supporting controls, failure response sequence, and protection of workers, public, environment, and samples.

HOW DO MULTIPLE LAYERS OF BIOLOGICAL CONTAINMENT PROTECT EARTH?

Infographic titled how scientists judge unusual findings in space samples, showing three possibilities—biosignature, earthly contamination, and abiotic chemistry—plus lists of clues for each and a six-step decision pathway ending in cautious interpretation of life claims.

BIOSIGNATURE, CONTAMINATION, OR NONLIVING CHEMISTRY?

Infographic explaining planetary protection: two main goals of blocking Earth microbes outbound and extraterrestrial material inbound, why it matters, how it works through planning and handling steps, where it applies to mission types, and key ideas including forward and back contamination.

WHAT IS PLANETARY PROTECTION?

Infographic explaining extraterrestrial sample-receiving facilities: purpose, sealed containment features, multi-room lab layout, eight-step workflow from capsule arrival to secure storage, scientific targets, planetary-protection reasons, and a secure facility site concept.

WHAT IS AN EXTRATERRESTRIAL SAMPLE-RECEIVING FACILITY?

Infographic listing nine sequential steps needed for an extraterrestrial outbreak, with side notes on low probability, chain-break points, and a closing statement that many independent failures would be required.

WHAT CHAIN OF EVENTS WOULD BE REQUIRED FOR AN EXTRATERRESTRIAL OUTBREAK?
