  1. LADEE Mission Definition Review underway! Teams are reporting where they currently are in spacecraft design.
  2. string test meeting: what is the schedule for design and fab? do we need another IMU? what is the propulsion MIB? Fun for all the family :o)
  3. Meeting about the dust detector instrument from LASP. Low power, low mass - an easy fit for the spacecraft. How do we maximise the science?
  4. LADEE weekly meeting -- debating the merits of one vs. two stage propulsion systems.
  5. LADEE weekly meeting -- how to deal with ITAR, units units units. Now detailed discussion on UVS2 mode, again.
  6. Requirements meeting. Vigorous debate about whether to: have safe mode for if reaction wheels fail; & send health status down every orbit?
  7. Team is debating pros and cons of different vendor propulsion systems. A critical decision for LADEE! 1 vs 2 stages? Nutation issues? etc
  8. Just noticed the LADEE entry in the National Space Science Data Centre! http://nssdc.gsfc.nasa.gov/...
  9. Lasercom payload meetings all afternoon -- structural mating to s/c, thermal survivability analyses, etc
  10. LADEE weekly meeting (though haven't had one for a while!!) -- new schedule being discussed!!
  11. LADEE mission overview -- how do we get from check out orbit to science orbits? do we need a slack period? Descend to the moon earlier?
  12. just finished string test meeting: requirements, mount trade, risk reduction, schedule
  13. LADEE contamination workshop: outgassing, particulates, and avoiding these landing on the optics.
  14. LADEE string test meeting -- should the test vehicle be mounted on an air bearing at its CG, or by an external 3-axis gimbal?
  15. LADEE team is discussing timeline of one of its science orbits in exquisite detail. Useful for each subsystem to know what else is going on!
  16. Discussing LADEE operations -- minute by minute what is the spacecraft doing over its lunar orbit.
  17. LADEE weekly meeting: requirements tree, propulsion contamination workshop, string test risk reduction, operations scenarios...
  18. LADEE is costing risk reduction activities
  19. LADEE is planning String Test of a prototype vehicle in order to test its attitude control system and software in an integrated set up.
  20. LADEE weekly meeting: general project update, discussions on antenna positioning, string testing, propulsion system and contamination.
