There are no firsts.

Here's a partial and very incomplete history of the operation of Internet-connected computers in space.

In 1996, an experiment onboard the STRV-1b satellite, conducted by NASA's Jet Propulsion Lab, gave the satellite an IP address and communicated with it.

In 2000, a TCP/IP stack was uploaded to the UoSAT-12 satellite, and some simple experiments were run by NASA Goddard. SSTL, who built UoSAT-12, went on to adopt TCP/IP for satellite control and telemetry in their Disaster Monitoring satellites. The first of these satellites, AlSAT-1, was launched in 2002.

In 2001, SoftPhone was used on a laptop PC onboard the space shuttle, talking VoIP the Internet way across a local Ethernet LAN that was connected to the shuttle's custom equipment that communicated with NASA Johnson Space Center. The laptop was orbiting, and commercial laptops had been used previously onboard the shuttle; the laptop was a node on the Internet.

The reason I mention all of this is that Jim Benson of SpaceDev is continually on record as saying that CHIPsat is the "first orbiting node on the Internet" -- yet CHIPsat was launched in January 2003. CHIPsat's launch delays aren't significant; all missions have launch delays.

And CHIPsat was built for NASA, an organisation that appears to have achieved the first orbiting node on the Internet a number of separate times. Still, those that do not know history are doomed to repeat it.
