Artemis II flew four astronauts around the Moon in April 2026, the first crewed lunar mission in more than fifty years.

Verdict

The call

The clearest difference is review sentiment: NASA at 70% against Artemis Mission Tracker's 24%. NASA also leads on rating (4.8 vs 4.2) and in-app purchases (none vs 7). Artemis Mission Tracker's advantage is update cadence (every 5 days vs every 2 weeks). On price and ads there is nothing between them.
