The correct answer is option 3, Atlantis. The NASA space shuttle program, which lasted for 30 years, came to an end in July 2011 when the final shuttle of the program touched down at the Kennedy Space Centre in Florida. The space shuttle that made this last landing was named Atlantis.

Option 1, Discovery, is incorrect. While Discovery was indeed one of the space shuttles used in the NASA program, it was not the shuttle that made the final landing in 2011.

Option 2, Endeavour, is also incorrect. Endeavour was another space shuttle in the NASA program, but it was not the shuttle that landed for the last time in 2011.

Option 4, Columbia, is incorrect. Columbia was tragically lost in a fatal accident in 2003, thus it could not be the shuttle that made the final landing in 2011.

In summary, the correct answer is option 3, Atlantis, as it was the space shuttle that landed for the last time in July 2011, marking the end of the 30-year NASA space shuttle program.
