What to do when the Delta IV Heavy launch is scrubbed, again? Using gamma ray measurements to estimate star formation history; Some hydrgen atome energy transitions and principle quantum number n

Greetings from Palmia Observatory

Well three times now we have been ready to watch for the rocket launch only to have it scrubbed.  So, what to do?  Let's review some recent observations using gamma rays to get star formation history.
