Is the hubble space telescope still in orbit?

Yes. Its orbit is expected to decay some time around 2013-2021. The telescope's
last maintenance has pushed its functionality to at least 2014.

The HST was deployed from the Space Shuttle Discovery during the STS-31 mission
in 1990. April 24, 2012 is the 22nd anniversary of its release into space, and it's
still doing valuable science and returning excellent data.
