CHIPSat is a NASA mission which will use full TCPIP in space.

So far as I know, the first amateur radio satellite with
it's own IP number was UoSAT-12 OSCAR-36 and the first
NTP over IP tests were done in April 2000.
Uplink was 9k6 on 145 MHz and Downlink 435 MHz, amateur band.
So yes we can say, "amateur radio satellites" were again first!!!

AMSAT NEWS SERVICE BULLETIN 128.02 FROM AMSAT HQ
SILVER SPRING, MD, MAY 07, 2000
TO ALL RADIO AMATEURS
BID: $ANS-128.02

NASA recently demonstrated the ability to use standard Internet
protocols to communicate with an orbiting spacecraft (just like any node
on the Internet). Engineers at NASA's Goddard Space Flight Center
working with the Operating Missions as Nodes on the Internet (OMNI)
project - have completed the first step in extending Internet access to
future spacecraft. AMSAT-NA's Ron Parise, WA4SIR, is one of the driving
forces in the project.

NASA has been developing this project by working with UoSAT-12, a
spacecraft built by Surrey Satellite Technology Ltd. (SSTL). UoSAT-12
is also known as UO-36 by the Amateur Radio community and carries a
number of imaging payloads, digital store-and-forward communications
and mode L/S transponders in addition to its commercial payload.

Engineers from the GSFC successfully used standard Internet PING
packets to communicate with UoSAT-12 through a ground station in
Surrey, England. This is the first time that a spacecraft ever had its
own Internet address and was a fully compliant active node on the
world-wide web.

Subsequent tests will expand on the basic network capabilities
established and will demonstrate the use of standard Internet
applications to support normal spacecraft operations. Automatic
spacecraft clock synchronization will be demonstrated using Network
Time Protocol (NTP), reliable file transfer will be demonstrated using
standard File Transfer Protocol (FTP) and finally, the Simple Mail
Transfer Protocol (SMTP) will be used to demonstrate automated file
store-and-forward.

Future tests are planned to incorporate technologies required to support
full operational deployment of Internet protocols on future space
missions.
