INTERNATIONAL SPACE STATION STATUS REPORT: SS04-015

     Father's Day came early for astronaut Mike Fincke, 225 
miles in space aboard the International Space Station, as he 
received the best present on Earth -- baby daughter Tarali 
Paulina Fincke. Tarali Paulina was born Friday, June 18.

Although Fincke is among thousands of American fathers whose 
service to the country has prevented them from attending the 
birth of a child, he is the first U.S. astronaut to have 
celebrated the event from space.

Fincke's wife, Renita, gave birth to their second child in 
Clear Lake, Texas. Fincke spoke to teams of flight 
controllers Friday in Russia and in Houston during a 
television downlink, thanking them for their support of his 
family and offering a celebratory cigar and candy to 
Expedition 9 Commander Gennady Padalka. Fincke also urged 
everyone to remember all those in service to their country 
and support them as they make similar sacrifices away from 
their families.

Today, Fincke and Padalka are getting ready for this week's 
planned spacewalk. The crew will venture outside Thursday to 
fix a device that's essentially a circuit breaker. They'll 
replace a Remote Power Controller Module (RPCM) that houses 
the faulty circuit breaker. The modules route power to one of 
the Control Moment Gyros (CMGs).

The Station has four CMGs. They control the orientation of 
the ISS in space. CMG 1 failed two years ago and will be 
replaced during the next Space Shuttle mission. CMG 2 was 
taken off line by the April 21 failure of the circuit breaker 
and should be restored by the RPCM's replacement. The two 
functioning CMGs adequately control the Station's attitude.

NASA Television coverage of the spacewalk begins at 4:30 p.m. 
EDT Thursday, June 24. Padalka and Fincke are scheduled to 
leave the Russian Pirs docking compartment at 5:50 p.m. EDT 
in Russian spacesuits. 

The two spacewalkers will move to the worksite, on the S0 
truss, covering part of the distance using the Russian Strela 
crane attached to Pirs. The replacement work should take 
about 4-1/2 hours. Other tasks may be performed if time 
allows.

The crew's Russian spacesuits require a line of sight to 
antennas on the Russian segment of the station, some distance 
from the worksite, to communicate with the ground and with 
one another. Communications access points have been 
identified and four basic hand signals have been developed 
should Padalka and Fincke need them.

In addition to the spacewalk preparations, the crew's 
attention last week was devoted to experiment activities. The 
crew used each other as subjects in mass measurement checks 
and Fincke worked with three of the Express Racks aboard the 
U.S. laboratory Destiny to load new software.

The crew conducted the first of three 48-hour in-flight diet-
logging sessions for the Effect of Prolonged Space Flight on 
Human Skeletal Muscle (BIOPSY) experiment. The experiment 
investigates the reductions in limb muscle size, force and 
power at the cellular level that are caused by microgravity. 
Crewmembers are recording their food consumption for the 
experiment, and biopsies were taken from their calf and foot-
flexing muscles before launch. Biopsies will be taken again 
immediately when they return to Earth in October.

The neuromuscular system is one of the human systems most 
affected by extended stays in space. Past space missions have 
shown weightlessness can cause deterioration of muscle fiber 
and physical strength. This research will determine how long 
it takes for weightlessness to affect skeletal muscles, so 
predictions can be made regarding muscle changes that may 
occur on a roundtrip flight to Mars.

The crew also served as test subjects for the Advanced 
Diagnostic Ultrasound in Micro-G experiment. Fincke set up 
the equipment, after which he and Padalka performed the 
ultrasound bone scans on each other by taking turns as 
operator and subject.

This research will be used to determine the accuracy of 
ultrasound in novel clinical conditions including: 
orthopedic, thoracic, and ophthalmic injury and dental/sinus 
infections; and to assess the ultrasound as a feasible option 
for monitoring in-flight bone alterations.
