Today we continue our tour of Special Targeting on the LROC Uplink team with obliques. An oblique view is any observation where LRO slews more than 30 degrees. A normal oblique for an LROC observation is 50-70 degrees. These obliques are different from our normal slews and extra special because of how much LRO has to move to acquire them. We are only allowed to take one of these every few weeks. When we do take them, they are a coordinated effort with the project and other instruments.
Welcome to the exciting world of Special Targeting! My name is Christian Alf, and I will guide you through this special adventure. As a member of the LROC Operations Staff I work on the Uplink Team, for which Zack gave an introduction. One of the responsibilities of an uplinker is to plan special observations. Don't be fooled, we love each of our 600+ images we target a day, but we dedicate a lot more time to a few of them. Typically, these observations require moving the whole spacecraft, coordinating with other instruments, or crunching some numbers to ensure the viewing geometry is optimal. There are five main types of special targets: Geometric Stereo, Obliques, Limb Views, Earth Calibrations, and Ride-alongs with other instruments. Since we target geometric stereo at a higher frequency, lets talk about them first.
Howdy! My name is Zack Bowles and I am one of the Uplink members of the LROC Operations team. Operations are mainly divided into Uplink and Downlink, with Uplink responsible for targeting images and generating command loads and Downlink is responsible for data integrity analysis and spacecraft/instrument monitoring. Uplink is also further subdivided into 2 components: Nominal and Special Targeting, with Nominal responsible for the majority of camera commanding while Special Targeting is responsible for planning slewed observations, calibrations, and any observation that requires coordination with the other LRO instruments.
Hello, my name is Tim Donnelly. As a member of the LROC Science Operations Center (SOC) I, along with two others, handle the Downlink duties of the SOC. As Shane Thompson posted earlier, the SOC has two teams - Up-link (UL) and Down-link (DL). UL plans the observation time-line for image acquisition, while DL is responsible for monitoring the LROC instrument health (via real-time and stored telemetry) and data processing (management & processing of all files delivered to the SOC from the Goddard Space Flight Center (GSFC) Mission Operations Center (MOC)). Our two teams constitute the Operations Team to which Ernest Bowman-Cisneros referred in his post last week.
