Space shuttle Discovery lifted off from Cape Canaveral, Florida, late Thursday afternoon, beginning what is expected to be its final mission.
NASA had halted its countdown at five minutes due to a computer problem related to safety on the "eastern range." But after a confirmation that all was good to go, the countdown resumed and the shuttle lifted off about three minutes behind its planned 4:50 p.m. ET launch.
The six-member crew will deliver a storage module, a science rig and spare parts to the international space station during its 11-day mission.
The liftoff comes after months of delays due to leaks and cracks in the external tank.
The last scheduled launch of space shuttle Endeavour is scheduled for April 19, and shuttle Atlantis is tentatively scheduled to launch during the summer.
ď»żA federal judge is set to formally approve three criminal counts being dropped from the corruption case of former Illinois Gov. Rod Blagojevich, a judicial source in Chicago tells CNN.
The racketeering, racketeering conspiracy and wire fraud charges were part of a broader indictment against Blagojevich, who faces re-trial in April.
The former governor still faces trial on 17 public corruption-related charges. He is accused of, among other things, trying to gain financially and politically as he weighed who to name U.S. senator when Barack Obama was elected president.
The first trial ended in August, when jurors convicted Blagojevich of lying to federal agents on one of 24 counts brought against him by the federal government. They deadlocked on all the other counts, and federal authorities soon thereafter signaled their intent to request a new trial.

10:30 am ET - Pentagon briefing on Afghanistan - ISAF and Afghan military officials brief reporters on current military operations in Afghanistan.
When Melissa Moorhouse got on a Red Line subway train in Boston on January 7, her pet snake, Penelope, was coiled cozily under her scarf.
When Moorhouse got off the train, Penelope, a Dumeril's boa, stayed behind, hiding somewhere in the car, CNN affiliate WCVB-TV reported.
A month passed before another passenger reported seeing a snake on the "T," as the Metropolitan Boston Transit Authority system is called. After another search, Penelope was found, safe and sound, and returned to Moorhouse.
But that's not all the T folks had for Moorhouse. This week she received a $650 bill, she told the station.
"To rid the subway car of any traces of germs such as salmonella, which may have been left by your snake, MBTA maintenance crews had to scrub and disinfect the Red Line car in which your snake was found," MBTA Treasurer-Controller Wesley Wallace wrote to Moorhouse.
Moorhouse didn't think she deserved the bill.
"I understand sanitizing the train, but shouldn't that be done anyway?" she told WCVB. "A lot of different people with a lot of different sicknesses are on that train. People throw up on the train, people bleed on the train. Do they have to pay to get it cleaned?"
The MBTA told Moorhouse she should use a pet carrier if she carries the snake on a train again.
