It also photographs science targets en route. Ingenuity must stay ahead of Perseverance in order to scout for it.
MARS HELICOPTER INGENUITY SERIES
Ingenuity commenced a series of frequent flights from this point through March to keep ahead of Perseverance, whose large no-fly exclusion zone prevents the two passing in the confines of the canyon. Scouting for Perseverance and photographing science targets. The flight plan called for the helicopter to turn nearly 180 degrees before landing to aim its color camera toward the river delta for future flights.ĭogleg northwest ~91 m (299 ft) landing back within Airfield Beta (β)ġ8☂7′32″N 77☂4′26″E / 18.459015°N 77.407090☎ / 18.459015 77.407090
This gradual approach is due to lack of large landing sites in the area and lower atmospheric density in the summer, which requires higher rotor speeds and more power. The flight was another in a series to return to Wright Brothers Field. Images taken during Flight 9 were used to select a safe zone. The helicopter flew out of South Séítah basin, across a dividing ridge and up to the main plateau, near the landing site of Flight 8. Repeated actuator self-tests and servo-wiggles cleared the debris. Dust and sand also accumulated in all the swashplate assemblies. To prevent navigation errors, JPL uploaded a new image mask file in late January that ignores certain regions of the image. The storm deposited dust on the navigation camera window. JPL waited over a month for the air to clear and the helicopter to regain its pre-storm power generating ability. The storm reduced sunlight by 18 percent on Ingenuity's solar array, which charges its batteries, and warm dust lowered the surrounding air density by seven percent, which could have exceeded Ingenuity's ability to generate adequate lift. The first attempt of flight 19 was postponed due to a dust storm approaching Jezero Crater, the first time weather delayed a flight of an airborne vehicle on a celestial object other than Earth. Originally planned for Janu(Sol 312) rescheduled for January 23 (Sol 330) flown on Febru(Sol 345). This was the first time the helicopter had to land at an airfield which was not surveyed by any means other than MRO satellite imagery. It flew in that mode until successfully landing about 5 m (16 ft) away from the planned spot, after turning off navigation camera and flying on IMU.
An image was dropped, and subsequent images with incorrect timestamps resulted in the craft tilting forward and backward up to 20 degrees, with large spikes in power consumption. Near the end of the first leg of the route at 54 seconds into flight, a glitch occurred in the navigation images processing system.
