8 marts 2009 Thermal Analysis Design temperature in space: ° C Design temperature on the moon: ° C This leads to an acceptable α/ε of between 0.65 and 0.88 The outer coating: shade of grey and heat conducting

8 marts 2009 Other specs HAL specs (linux) Connections: USB Operation (out of rocket, attitude control, burn 3100 m/s, wait 4 month, turn around, break, land..) Link budget: large disc needed.

8 marts 2009 Mechanical and vibration analysis Mechanical issues on connection between the two tanks. Vibration analysis not made yet, but assumed to be no serious problem…

Solar cell navigation (!) By measuring the solar input to the 6 solar cells, we get a rough direction/orientation of the spacecraft. Power measurement can handle this ?

Mission plan outline

8 marts 2009 Mission plan TimeAction 0Ejection from storage bay, Health check, status of all systems. Transmit to ground control Use GPS, navigation cameras to determine position Calculate orbit, using position data Calculate time to burn (T1). Change attitude for 1 st burn, initiate rotation about longitudinal axis

8 marts 2009 TimeAction T1First burn, constant GPS position measured for monitoring Position determined from GPS, Earth-Moon- Sun images. Course compliance monitored for possible corrections Calculate time till arrival in hyperbolic trajectory, T2 Determine whether there is fuel enough for orbiting the Moon or if landing has to be immediate.

8 marts 2009 TimeAction T2Arrival in Moon Hyperbolic trajectory. Decision is carried out; attitude corrected and thruster fired If we obtain a circular orbit, Newtonian height and velocity are calculated and correlated with crater images. Results are transmitted to ground control Calculate optimal landing place and time (T3) T3Initiate landing sequence Send confirmation of successful landing

8 marts 2009 Moon operation mission plan Given by GLXP requirements Turn craft if upside down, drive 500 m Long term survival prize for restart after lunar night. Insulate components, other options ?

8 marts 2009 Discussion Main conceptual design frozen Mechanical design still evolving Offer for launch end of 2009 – but maybe Geo Transfer orbit in 2010 We need to go commercial off the shelf, rather than custom designed.
