Jack Swigert was moved from the backup to the prime crew for the Apollo 13 mission because the original prime crew member, Ken Mattingly, was exposed to German measles and was deemed non-immune. Swigert's experience as a backup crew member and his ability to step in at short notice made him a suitable replacement for Mattingly.
Astronaut Jack Swigert got sick on Apollo 13 with a urinary tract infection shortly before launch, but he recovered in time to fly the mission.
The backup crew for Apollo 11 was James Lovell (CDR), Fred Haise (LMP) and Ken Mattingly (CMP). They later became the prime crew for Apollo 13, though Mattingly was removed from the Apollo 13 crew a few days before launch due to exposure to measles. Jack Swigert, Apollo 13 backup CMP, replaced him. Mattingly later filled what would likely have been Swigert's originally-planned seat on Apollo 16.
The original crew of Apollo 13 consisted of Commander Jim Lovell, Command Module Pilot John Swigert, and Lunar Module Pilot Fred Haise. Jim Lovell had previously flown on Apollo 8 and Apollo 11, while John Swigert and Fred Haise were making their first spaceflight. However, due to a change in the crew before launch, Ken Mattingly, who was initially assigned as Command Module Pilot, was replaced by Swigert after he was exposed to German measles.
Yes, Ken Mattingly contracted the measles prior to the Apollo 13 mission. As a result, he was replaced by astronaut Jack Swigert shortly before the launch because NASA wanted to avoid any risk of him spreading the virus to the crew. Mattingly's experience and skills were critical, but he ultimately had to stay on the ground during the mission.
It is a little burnt but the launch pad is designed to take extreme heat and pressure created by the space shuttle. If it wasn't, they would have to make a new launch pad every launch and those things are worth a pretty penny...
No, the backup crew of a space mission is in training and preparing well before the launch. If something happens to a primary crewmember before launch, the backup person may take his place, or the entire mission may be rescheduled.

To reinstall a backup of the computer registry, first, ensure you have a valid registry backup file (usually with a .reg extension). Open the Start menu, type "regedit" to launch the Registry Editor, and select "File" > "Import." Navigate to your backup file, select it, and click "Open" to restore the registry settings from that backup. Always create a new backup of the current registry before making changes to avoid potential issues.
The 3 astronauts who flew on Apollo 13 were Jim Lovell (Commander), Fred Haise (Lunar Module Pilot), and Jack Swigert (Command Module Pilot). Swigert replaced Thomas "Ken" Mattingly 3 days before the launch of Apollo 13 when it was discovered that the son of Charlie Duke, the backup, had caught the measles. Mattingly had not had the measles before, so he was replaced on the flight by Swigert. Apollo 13 was Swigert's only flight. He resigned from NASA in 1977. In 1982, he ran a successful campaign for House Representative from the state of Colorado. Unfortunately, he died of bone cancer 8 days before he was to be sworn in. Lovell and Haise are still alive.
Acronis Mac backup software launched on or about 8 March 2013. It is easy to use data backup and hard drive recovery software that is used by millions of people worldwide.
