The International Space Station (ISS) reached a higher orbit Monday afternoon after a successful boost from a docked Russian supply ship.

Lynette Madison, a NASA spokesperson at the agency’s Johnson Space Center in Houston, told SPACE.com that a planned 23-minute engine burn by the Russian-built Progress 23 currently berthed at the station went off without a hitch.

The space station is now primed for the planned Saturday arrival of NASA’s Discovery shuttle. Discovery is set to launch seven astronauts spaceward on Dec. 7 at 9:35: 47 p.m. EST (0235:47 Dec. 8 GMT) to kick off the STS-116 mission that will continue ISS construction.

“It allows unbroken launch attempts through the 23rd [of December] and on the 25th,” Madison said.

Without today’s orbital reboost maneuver by Progress 23, which began at about 4:36 p.m. EST (2136 GMT) the launch opportunities for Discovery would have been limited to odd days between Dec. 7 and the 15th, with daily windows on the 16th and 17th. NASA’s launch window for STS-116 currently runs through Dec. 17, but could be extended later should shuttle mission managers approve Discovery for flight over the end-of-year rollover.

Madison said today’s ISS reboost raised the space station’s orbit by about 656 feet (200 meters), leaving it on a flight path that reaches 219.5 statute miles (353 kilometers) at apogee—its highest point—and 205.9 statute miles (331 kilometers) at its lowest point, or perigee.
