EVA Number: 22
EVA Name: Long-Duration GeoMars and W-Lan setup Engineering

Objectives: Go to the coordinates NAD27 UTM 14254022m, N 517945m E and collect three geological samples from the soil and from a vertical wall, including also a core drill. Afterwards proceed to coordinates NAD27 UTM 14252416m N, 514714m E on top of Skyline Rim. If time permits establish the WLAN repeater at Repeater Hill in alignment with Operation Edelweiss.

Narrative: Today was the day we wanted to get up on Skyline Rim, using the route that the MSP (C. Kandler) and MSL (M. Spiss) had scouted out on April 17th. This GeoMars EVA led us first to NAD27 UTM 14254022m, N 517945m E, where we were ordered to collect three geological samples from the soil and from a vertical wall, including also a core drill. Afterwards we proceeded along Brahe Road to the foot of Skyline Rim as were ordered to take a geological sample at coordinates NAD27 UTM 14252416m N, 514714m E on top of Skyline Rim, in alignment with - Operation Edelweiss. This point was later on called - Thajer Joch by our MSL and from here we made a southbound excursion of the Skyline Rim Plateau, reaching finally NAD27 UTM 14251529m N, 515207m E, 1517m MSL - Kap AustroMars and afterwards NAD27 UTM 14251480m N, 515230m E, 1521m MSL - Andreas' Buena Vista. Here we were able to establish radio communication with the MDRS, even though the Repeater Hill radio device is non-operational. Communications were not perfect but in pilot's terms (reading 1- 5) at scale 3-4. After a 360° Panorama shot and a careful look at Factory Butte, we headed back to the MDRS, establishing another waypoint at the beginning of the route on top of Skyline Rim (NAD27 UTM 14252358m N, 514802m E, 1448m MSL - Thoar Tirala), so that later crews can also find the way for further exploration of Skyline Rim and Factory Bench. As we were able to establish radio communication, the WLAN setup at Repeater Hill was skipped/postponed.
