Thanks a lot. It works now.

hello as I mentioned above in the post , I am not getting any error message the node keeps on running but one more thing I found out was while using rosrun I have to run simulator node before mission control node for it to work otherwise between the nodes no data is passed. Thank you

I have two nodes - Mission Control and Simulator. Mission control publishes to command topic and subscribes to telemetry topic while simulator node subscribes to command topic and publishes to telemetry topic. When I use rosrun both runs fine but only mission control node runs when I use roslaunch command. the printed message on the terminal is "The Goal Latitude is 33 and Goal Longitude is -84" and it keeps on running ... No error message. I also know that both nodes are running (used rosnode list to check it). Also both telemetry topic and commands topic are running (rostopic list) The following is my XML code. Please help. Thanks in advance.

<launch>
  <group> 
    <node pkg="groundcontrolstation" type="missioncontrol.py" name="mission_control"  output="screen"/>
    <node pkg="groundcontrolstation" type="simulator.py" name="simulator" output="screen" />
  </group>
</launch>
