Purpose of Flight:Science
Comments:Third local flight completing the engineering checkout of the GEO TASO instrument. Essentially a repeat of the flight pattern flown yesterday. Flight crew was Greg Slover, Les Kagey, and Mike Wusk from Langley and Shaun Ashby and Jeremy Craner from Ball. Flight plan included an hour plus at 30000' completing multiple legs over the Richmond urban area and rural areas to the south of Richmond, and a doglegged run down over the Langley and Norfolk areas. Then a return a the Richmond area North-south leg flown at FL360, FL240, and 11,000'. The flight finished by continuing along the same leg flown toward LFI previously but this time at 11,000'. Landing and shut down were all nominal. The weather was hot,hazy. Below is Tom Belker's daily email summary. Shaun and Jeremy are back safely from the morning sortie with another successful mission completed. As planned, they repeated the same flight pattern with approximately a one hour earlier take off and the 39 um slit. The weather was very similar to the previous day, but hazier and slightly more cloud build-up toward the end of the flight. No software anomalies this time. All the objectives of the engineering flights have been met. Here is the current status of the matrix, although we still need to provide level 1B data to our science team members for them to perform the retrievals.

At one point we were hoping to remain on the aircraft until the September flight, but there is a mission planned that we are not compatible with. We will provide pseudo-1B data to the science team in the meantime using our initial lab measurements of subsystem performance in order to start getting final data products from the instrument. Congratulations GeoTASO and Langley team mates! It was through your hard work and attention to detail that we were able to have such successful engineering check-out flights!
