Extraterrestrial Life | New Space Economy

Timeline infographic describing planetary protection from the 1960s–1970s Apollo era through the 2030s and beyond, including lunar quarantine, Mars mission standards, COSPAR guidance, asteroid sample return, containment, biosafety, and international coordination.

HOW HAS PLANETARY PROTECTION CHANGED SINCE APOLLO?

Educational infographic outlining dormant viral infections, spaceflight-related immune stressors, possible health effects, surveillance methods, and measures intended to support crew health.

WHY CAN DORMANT VIRUSES REACTIVATE DURING SPACEFLIGHT?

Infographic explaining how microgravity, radiation, closed habitats, and resource limits can influence microbes, summarizing International Space Station and Tiangong evidence and discussing risks for crews and future lunar and Martian missions.

PATHOGEN RESILIENCE AND EVOLUTION IN SPACE

Infographic explaining the two directions of planetary contamination, their scientific and safety risks, common safeguards, and examples involving a Mars lander and a sample-return capsule.

FORWARD CONTAMINATION VS. BACK CONTAMINATION

Infographic explaining how infections can spread among spacecraft crews through shared air, surfaces, supplies, food, water, and body fluids, with sections on high-risk areas, prevention, and mission impacts.

HOW COULD AN INFECTION SPREAD THROUGH A SPACECRAFT?

Infographic summarizing panspermia, including natural and intentional transfer routes, hazards faced during space travel, conditions that may protect organisms, laboratory findings, and implications for life detection and planetary protection.

COULD LIFE TRAVEL BETWEEN WORLDS?

Educational infographic summarizing how microgravity changes microbial growth and behavior, why effects vary, possible implications for crews and spacecraft systems, and methods used to study microbes in space environments.

HOW DO MICROBES BEHAVE DIFFERENTLY IN MICROGRAVITY?

Infographic summarizing panspermia, possible microbial transport by comets and meteors, supporting evidence, survival obstacles, distinctions between bacteria and viruses, and the conclusion that active pathogen delivery to Earth has not been confirmed.

COULD COMETS AND METEORS BRING BACTERIA AND VIRUSES TO EARTH?

Infographic defining hazard as potential to cause harm, exposure as contact with the hazard, vulnerability as susceptibility, consequences as outcome severity, and risk as chance and severity under real conditions; a contained space-sample example shows risk changing when containment fails.

WHAT IS THE DIFFERENCE BETWEEN HAZARD, EXPOSURE, AND RISK?

Infographic describing a five-stage process for responding to a possible extraterrestrial biological signal, including verification, authority notification, public communication, continuing updates, communication principles, common mistakes, and four evidence levels.

HOW SHOULD AN EXTRATERRESTRIAL BIOLOGICAL ALERT BE COMMUNICATED?
