- IceBridge is a 2009–2018 NASA mission that aims to monitor changes in polar ice from a fixed-wing aircraft.
- It is a temporary replacement for the ICESat satellite until the ICESat-2 launch in 2018.
- Since 2003 NASA has used a satellite, ICESat (Ice, Cloud, and land Elevation Satellite), for observing polar ice.
- ICESat was retired in 2009 due to a technical malfunction, leaving NASA without a satellite dedicated to ice observance.
- NASA therefore introduced the IceBridge program which utilizes an aircraft to make similar measurements.
