Holmes Frost 02

OIB resumed science missions following our rest day with a successful “Holmes Frost 02” land ice mission today. Weather was good, but the flight lines parallel to the coast were turbulent in places. All OIB instruments on the NASA Gulfstream V continued to function nominally. To ensure fuel reserves, NASA 5 began climbing to cruise altitude just before the last ICESat-2 crossing, missing the last few minutes of the planned science coverage otherwise 100% data coverage was obtained on the low altitude science lines. A calibration ramp overflight at 1200’ was conducted just before landing.

Weather permitting we’ll make another OIB science mission attempt tomorrow.
