NASA’s Simulated Mars Mission Marks 200 Days Inside Habitat

The four crew members of NASA’s Mars simulation recently marked 200 days into their 378-day Red Planet mission on May 7. Currently, the crew is in a simulated two‑week loss‑of‑signal period that mimics a Mars-Earth communications blackout when Mars moves behind the Sun.
