Limits RegistryNASA's Sojourner rover, part of the Mars Pathfinder mission, became the first wheeled vehicle to operate on Mars after landing on July 4, 1997 — a small, microwave-oven-sized rover that operated for nearly three months, proving the viability of robotic rovers for planetary exploration and paving the way for later, much larger rovers like Curiosity and Perseverance.

The year the first wheeled robotic rover successfully operated on the surface of Mars.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
