 Hubble's importance to science is not just seen in the dramatic images it provides, but also in the volume of work it has generated – an average of fourteen scientific articles are published each week based on data gathered from the telescope.Officially, the upgrades should extend Hubble's life through 2014, but Hubble Space Telescope Senior Scientist David Leckrone noted prior to the mission that if all of the mission's objectives were successful, the telescope could easily last longer than that.The next large telescope scheduled to be launched is the James Webb Space Telescope in 2020, which is infrared-only, so to have Hubble, which has ultraviolet, visible, and near-infrared capabilities, still operational after 2018 would be of great benefit to the scientific community.
