Under 0810 you can reactivate orbiter by sending an Activate Orbiter message, with the value set to 0.
This can be done from the web admin, by selecting the Onscreen Orbiter from the advanced > devices page. and clicking send command, clicking Activate Orbiter from the commands pull-down, and clicking send.
You can also send it with the following command.
#!/bin/sh
/usr/pluto/bin/MessageSend localhost 0 20 1 912 119 "1"
This will not be needed once a full UI to the launch manager is available.
