(CNN) — The space shuttle Endeavour successfully landed at California’s Edwards Air Force Base on Sunday afternoon. Poor weather conditions forced NASA to cancel two potential landing opportunities in Florida.
Endeavour glides in for a landing Sunday at California’s Edwards Air Force Base.
The shuttle, under the command of Christopher Ferguson, touched down at 1:25 p.m. This concludes a mission that lasted more than two weeks.
Due to strong winds, rain, and thunderstorm reports within 30 miles of the Kennedy Space Center in Florida, NASA decided to abort the landing attempts. The scheduled landing times were 1:19 p.m. and 2:54 p.m. ET.
After assessing the unfavorable weather forecast for Monday at the Kennedy Space Center, flight controllers opted to land the shuttle and its seven astronauts at Edwards AFB in California. The forecast for California on Sunday was sunny.
Flight controllers usually prefer landing at Kennedy Space Center due to cost and schedule considerations. It is estimated that it costs about $1.7 million to bring a shuttle back to Kennedy Space Center from California.

Additionally, preparing the shuttle for the journey takes at least a week. However, the schedule is not a major factor for Endeavour as it is not expected to fly again until May.
The 15-day mission of Endeavour to the international space station began on November 14 and featured four spacewalks.
During this time, the crew delivered essential pieces of equipment, including exercise gear, additional sleeping quarters, and a urine recycling system. These items are part of a project to double the capacity of the station from three astronauts to six.
The urine recycling system was installed to convert astronauts’ urine and sweat into drinking water.
More modules are set to arrive during a shuttle flight in February. The goal is to expand the station’s capacity to six astronauts by the summer.
The crew also spent time working on a joint that contributes to power generation for the space station. Astronauts Heidemarie Stefanyshyn-Piper and Steve Bowen dedicated hours cleaning and lubricating the Solar Alpha Rotary Joint, which allows the solar panels on the left side of the station to rotate and track the sun.
The astronauts also replaced several trundle bearing assemblies.
Despite a minor setback on the first spacewalk when a grease gun in Stefanyshyn-Piper’s bag leaked, causing everything inside to be coated with a film of lubricant, the mission went smoothly. While attempting to clean up the mess, her bag, containing $100,000 worth of tools, floated away.
