NASA plans careful restart for Mars helicopter after quiet period

Science
Oct. 1 (UPI) -- The Mars helicopter Ingenuity is on its own without NASA's guidance for two weeks as the sun interferes with communications to the Red Planet. Sometime around Oct. 14, NASA plans to check in with the helicopter and the Mars rover Perseverance. Previous rovers have endured so-called solar conjunction communication dropouts, but never has a tiny aircraft sat alone on the planet for so long with no Earthly contact. "Ingenuity is unique, something never tried before," Jaakko Karras, Ingenuity deputy operations lead, told UPI.

Mars Ingenuity flight delayed after rotor test fails

Science
April 10 (UPI) -- NASA has delayed the first flight of the Ingenuity Mars helicopter until at least Wednesday. The agency announced the delay in a Saturday news release after a high-speed test of the helicopter's rotors abruptly stopped Friday.

The watchdog timer oversees the command sequences and alerts the system to any potential problems, preventing the system from proceeding when an issue is detected. NASA described the helicopter as "safe and healthy" and said the Ingenuity Mars' team is reviewing telemetry to diagnose and understand the full-speed test. Friday's test was the last major one before the helicopter's first scheduled f...
