The External Tank Laboratory (ETL) is a research facility that is being assembled in low Earth orbit by the International Space Agency. On-orbit construction of the station began in 2010 and is scheduled for completion by late 2011. The station is expected to remain in operation until at least 2025, and likely 2030. With a greater cross-sectional area than that of any previous space station, the ETL can be seen from Earth with the naked eye, and is by far the largest artificial satellite that has ever orbited Earth. The ETL serves as a research laboratory that has a microgravity environment in which crews conduct experiments in biology, chemistry, medicine, physiology and physics, as well as astronomical and meteorological observations. The station provides a unique environment for the testing of the spacecraft systems that will be required for future missions to the Moon and outer Solar System.
