ESA's Huygens probe, now orbiting Saturn on board the
NASA/ESA/ASI Cassini spacecraft, is in good health and successfully
passed its sixteenth 'In-Flight Checkout' Sunday.
This in-flight checkout procedure was the last one planned
before separation of the Huygens probe from Cassini in December
this year. The preliminary analysis of the real-time data received
showed all events in the check-out procedure occurred as, and when,
The procedure was carried out live, with Cassini transmitting
the data to Earth in real-time. However the data arrived on Earth
with a delay of one hour and 10 minutes as this is the time taken
for light, and therefore radio signals, to travel the distance
between Saturn and Earth.
