Efforts included the swift removal of roadkill and other dead animals from areas around the launch site. This followed a near miss during STS-114. Again, the countdown continued according to schedule with a launch time of 15:26. At 09:30 on July 2, 2006, the NASA launch blog reported that the "shuttle weather officer forecasts a 70-percent chance of weather prohibiting a launch this afternoon due to thunderstorms and anvil clouds. There is a 60-percent chance of weather prohibiting launch should there be a 24-hour turnaround, and a 40-percent chance with a 48-hour delay. If we scrub today due to weather, mission managers will meet later to decide if they want to make a third consecutive launch attempt or stand down for one day and try again on Tuesday." At 13:14, the launch director made a final decision to scrub again due to unfavorable weather conditions. The next launch attempt was scheduled for around 14:38 pm on July 4, 2006. The shuttle's fuel cells were replenished to improve the chances of having enough electrical power on orbit to enable the third planned space walk to take place. Cracks and a region where a piece of foam had come off were discovered in the insulation on the upper part of the external fuel tanks. The foam came off a bracket which held an oxygen line in place. The fragment that fell off weighed and, according to NASA, would not be big enough to damage the shuttle if it were to come off during flight. The thermal stresses of repeated filling and emptying the fuel tank with the cryogenic fuel are known to cause a degree of damage to the insulation foam. At 08:35 the backup circuit breaker controlling the primary heaters on the segment joints of both solid rocket boosters were noticed to have failed. Consideration was given to a repair on the pad. However, this was not done as the heaters are only used in colder weather, and the primary heater was functional. For the third launch attempt, there was only a 20% chance of weather preventing launch according to NASA. At 14:37:55 Eastern Daylight Time, Space Shuttle Discovery launched from the Kennedy Space Center at Cape Canaveral, Florida. This was the third attempt at launch. It was also the first US Space Shuttle to launch on the United States' Independence Day. During and after launch much attention was paid to
