However, as the Nature article discusses, parts of NASA that work with Hubble are affected.
The general impact of the shutdown on NASA has been widely reported:
> Most NASA personnel will be furloughed until such an agreement is reached, agency officials explained recently in a [shutdown FAQ](https://www.nasa.gov/sites/default/files/atoms/files/shutdow...). "Most" is something of an understatement, in fact; about 95 percent of NASA employees won't be able to go to work.
STScI/APL in Baltimore, like JPL in Pasadena, are technically contractors. As described nearby, they are still at work like normal due to the float in money already sent (to Hopkins/APL or Caltech, respectively) but not yet dispersed.
Of course, those folks are looking on anxiously as this fiasco plays out, designing telescopes, probes, and rovers like usual, but with uneasy coffee room conversations.
