| 29 July 1998 17:45:55 GMT | The Remote Agent Experiment is up and running!
Setting Remote Agent clock to 21 May 1999 14:48:53 GMT. |
| 21 May 1999 14:49:47 GMT | The spacecraft components are in the following states: |
| 21 May 1999 14:50:09 GMT | Rotating the spacecraft:
Point the spacecraft's +x axis at Earth, and the solar panels at the sun. |
| 21 May 1999 15:07:57 GMT | Starting a pre-programmed script that simulates failure of the LPE bus terminal to test RAX. |
| 21 May 1999 15:07:58 GMT | Turning Power Activation and Switching Module on. |
| 21 May 1999 15:08:04 GMT | Nothing happened. |
| 21 May 1999 15:08:40 GMT | Spontaneous spacecraft state change just detected: |
| 21 May 1999 15:08:40 GMT | RAX is looking for a way to recover.
The recovery will have achieve or maintain the following:
- Make it so steering with thrusters is working okay.
- Make it so ACS is steering with thrusters.
- Make it so Low-Power Electronics subsystem is working okay. |
| 21 May 1999 15:08:40 GMT | RAX has decided to reset Low-Power Electronics subsystem in an attempt to recover. |
| 21 May 1999 15:08:40 GMT | Resetting the bus terminal for Low-Power Electronics subsystem. |
| 21 May 1999 15:08:46 GMT | Command resulted in the following state change: |
| 21 May 1999 15:08:46 GMT | The LPE failure simulation is over. |
| 21 May 1999 15:37:57 GMT | ;; [:EXEC-ACT :INTERESTING 43645139.016]
;; Simulating NEB1 status throw failure
;; |
| 21 May 1999 15:38:09 GMT | ;; [:EXEC-ACT :INTERESTING 43645150.313]
;; End of NEB1 fault simulation.

| 21 May 1999 15:44:37 GMT | Spontaneous spacecraft state change just detected: |
| 21 May 1999 15:46:39 GMT | The Remote Agent is developing a plan to achieve specified mission goals, given the current state of the spacecraft. |
| 21 May 1999 15:58:04 GMT | RAX has finished developing a plan for the next horizon. |
| 21 May 1999 17:11:45 GMT | RAX has started to execute the plan. |
| 21 May 1999 17:13:55 GMT | Rotating the spacecraft:
Point the ion engine thrust at ra 4.187, dec -0.359, x=-0.470, y=-0.810, z=-0.351, and the solar panels at the sun. |
| 21 May 1999 17:13:56 GMT | Setting ion propulsion timer to 1.7 hours. |
| 21 May 1999 19:23:51 GMT | The Remote Agent is developing a plan to achieve specified mission goals, given the current state of the spacecraft. |
| 21 May 1999 19:31:53 GMT | RAX has finished developing a plan for the next horizon. |
| 21 May 1999 20:43:56 GMT | Rotating the spacecraft:
Point HGA at Earth, and the solar panels at the sun. |
| 21 May 1999 20:46:22 GMT | Starting a pre-programmed script that simulates failure of a thruster valve to test RAX. |
| 21 May 1999 20:46:25 GMT | Spontaneous spacecraft state changes just detected:
- steering with thrusters is degraded but usable.
- Earth standby capability is degraded but usable.
- sun standby capability is degraded but usable.
- X-thrusters-for-Y capability has failed and appears unrecoverable.
- Z-thrusters-for-Y capability is degraded but usable.
|
| 21 May 1999 20:46:25 GMT | RAX is looking for a way to recover.
The recovery will have achieve or maintain the following:
- Make it so MICAS camera is powered on.
- Make it so steering with thrusters is working okay.
- Make it so ACS is steering with thrusters.
- Make it so Low-Power Electronics subsystem is working okay. |
| 21 May 1999 20:46:26 GMT | RAX has decided to command ACS to use its Z-thrusters-for-Y capability in an attempt to recover. |
| 21 May 1999 20:46:56 GMT | RAX has finished executing the script that simulates the valve failure. |
| 21 May 1999 20:47:27 GMT | Command resulted in the following state changes:
- Thruster steering is using Z-thrusters-for-Y (slow) mode.
- steering with thrusters is working okay.
- Earth standby capability is working okay.
- sun standby capability is working okay.
