The record outlived the link

The November 1997 mission review and a later orbital image in 2006

Told in Pathfinder & Sojourner’s imagined voice · the events are real · source

Large boulders are visible in this enlargement of pictures taken by the Imager for Mars Pathfinder (IMP) lander camera on July 4, 1997.

01NASA records hundreds of rover photographs, thousands of lander images, rock chemistry and extensive weather observations. A panorama may combine many frames, so a beautiful stitched view is not a single instantaneous exposure.
Even the totals need their source labels.
02The later NASA Science page reports 2.3 billion bits; the contemporary ending report gives 2.6 billion. We show both in the evidence ledger, not an invented combined figure. Source differences remain visible to readers and judges.
The Mars Pathfinder began the journey to Mars with liftoff atop a Delta II expendable launch vehicle from launch Complex 17B on Cape Canaveral Air Station.

03NASA's history article includes a Mars Reconnaissance Orbiter view identifying the Pathfinder lander. It does not establish Sojourner's exact final position or prove that either spacecraft's electronics still work.
One stayed. One rolled. Their evidence helped the next explorers.
04Pathfinder demonstrated landing technology and Sojourner demonstrated surface mobility and science. Both became predecessors of later Mars exploration. Their authentic legacy is what the record supports—not an invented final message from the dust.

The big idea

Mission records can continue teaching after the link ends. Their value includes discoveries, engineering lessons and clearly preserved limits on what is known.

Think about it

Which unanswered question would you preserve for a future investigator rather than fill with a guess?
