English: The place once named “Twitcher’s Point” now is renamed to “van Zyl Overlook”, in commemoration of Japie van Zyl (1957–2020), the co-director of the JPL from 2011. In 2016 van Zyl became the director of solar system exploration at the JPL, where he was responsible for all the missions to planets in the outer part of the solar system.

The following text is from the „Ingenuity Mars Helicopter Landing Press Kit” published in January 2021 besides this map:

A schematic of the flight zone (blue oval where Ingenuity will conduct its first flight activities. First, Perseverance will drop the debris shield covering Ingenuity, drive to the helipad (innermost box) to drop off the helicopter, and then move out to a safe distant at Twitcher’s Point (the star). The helicopter would start its test program at the helipad, fly out a pre-programmed flight path, and return again to the helipad.

“Twitcher” is a British (and now Martian) term for those who travel long distances to see a rare bird. Located about 330 feet (100 meters) from the edge of the flight zone, the site should be relatively level. Twitcher’s Point also must allow direct line-of-site between the rover and the helicopter during all portions of potential flight tests for optimal radio communications and imaging.
