With no major activities or checkouts planned this week, flight 
controllers in Houston and Moscow continue to monitor the International 
Space Station, reporting that all systems aboard are operating normally 
and the spacecraft is in excellent condition.
The station has remained in a naturally stable orientation, with the 
Unity module pointing toward Earth and the Zarya module pointed toward 
deep space, slowly spinning at a rate of about one revolution each half 
hour. This orientation conserves propellant and provides moderate 
temperatures for the station. Flight controllers successfully completed 
a round of deep-cycling the six station batteries housed in Zarya late 
last week, individually fully discharging and recharging them as a 
routine housekeeping procedure that optimizes the batteries' 
performance. Similar deep-cycling activities will be conducted about 
every two weeks.
On Sunday, Jan. 10, flight controllers plan to briefly stop the 
station's spin to allow an update of the onboard guidance system, 
another standard station maintenance activity that is performed 
periodically. Following the update, the station will be commanded to 
resume its spinning orientation, the preferred orientation for the 
station as it awaits the next station assembly mission, a visit by the 
Space Shuttle Discovery on mission STS-96 in May.
The International Space Station is in an orbit with a high point of 256 
statute miles and a low point of 248 statute miles, circling Earth once 
every 92 minutes. 
Current opportunities available for locations worldwide to view the 
station from the ground as it passes overhead can be found on the 
internet at
The progress of preparations for Discovery's upcoming visit to the 
station can be found on the Kennedy Space Center's Space Shuttle status 
report located on the internet at
The next International Space Station status report is planned to be 
issued on Wednesday, January 13, 1999.
