4 Science claim verifications about National Aeronautics and Space Administration National Aeronautics and Space Administration ×
“NASA's Artemis II mission was staged using a green screen rather than being a genuine spaceflight.”
No credible evidence supports the claim that Artemis II was staged on a green screen. The viral images and videos cited as "proof" of staging were traced to AI-generated fabrications bearing Google SynthID watermarks, while broadcast visual anomalies were explained as standard overlay and recording artifacts. Independent verification from NASA, the Canadian Space Agency, ground-station telemetry, and multiple international fact-checkers all confirm the mission was a genuine crewed lunar flyby.
“Astronauts captured the first-ever Earthset image from space.”
The Artemis II crew did photograph Earth setting behind the Moon's far side on April 6, 2026 — a genuinely notable achievement. However, the unqualified "first-ever Earthset image from space" framing overstates what authoritative sources confirm. NASA's own releases describe the photo as "reminiscent" of Apollo 8's Earthrise rather than declaring it a verified first. The "first-ever" label traces primarily to a secondary media headline, and the claim omits that uncrewed spacecraft or earlier missions may have captured similar imagery.
“The Lunar Gateway space station is not necessary for NASA's Artemis program to achieve its lunar objectives.”
This claim is misleading. While it's true that early Artemis missions (II and III) were designed to proceed without the Lunar Gateway, NASA's own documents call Gateway "essential to the Artemis architecture" for the full campaign. Artemis's stated lunar objectives include establishing a sustained, long-term presence on the Moon — not just a single crewed landing — and Gateway is designated as central to Artemis IV and beyond. The claim cherry-picks a narrow near-term truth and presents it as applying to the entire program.
“Human activity is the primary driver of observed climate change since the mid-20th century.”
This claim is true. The world's leading scientific institutions — including the IPCC, NASA, NOAA, and the National Academies — independently confirm that human greenhouse gas emissions are the primary driver of observed warming since the mid-20th century. Quantitative attribution studies show human activity caused approximately 1.07°C of warming, while natural factors (solar, volcanic) contributed only –0.1°C to +0.1°C. A small number of low-authority dissenting sources exist but provide no peer-reviewed evidence that overturns this conclusion.
