About Mars Progress
Mars Progress is an independent news site and live tracker for everything heading to Mars. Every fact on it is dated and sourced, and every live number is calculated in your browser.

What we cover
SpaceX’s Starship, NASA’s rovers and orbiters, Japan’s MMX, and the missions from Europe, China and the UAE: every mission heading for Mars, plus the live numbers that tell you where Mars is right now.
We explain the jargon as we go. A word with a dotted underline, like SolA sol is a day on Mars — 24 h 39 min 35 s, about 40 minutes longer than ours — and rovers count them from the day they land.More in the glossary, opens a one-line definition.
How we work
- Primary sources first. NASA, ESA, JAXA, CNSA and SpaceX themselves. News outlets are labeled as secondary sources, and Wikipedia is never the only source for a fact.
- Dated, never vague. Every page shows the date it last changed. Dates are only as precise as their source: no countdown unless the time is exact.
- Mistakes are fixed the same day we confirm them, against a primary source.
- AI-assisted, human-approved. We use AI tools, mainly Anthropic’s Claude, to research, draft and check our pages and stories. Every fact is checked against the sources listed with it, and the editor approves each news story before it goes live.
- Independent. Mars Progress is not affiliated with NASA, SpaceX or any space agency.
Who makes it
Mars Progress is built and edited by Aleksandar Simov, and published by Simov Studio LTD, a company registered in Cyprus (registration HE 485117, VAT CY60286225D). Stories carry the byline “Mars Progress” and name the editor. Each one is checked against the sources listed at its foot before it goes live, and again whenever the facts change.
