It was named after the famous scientist Edwin P. Hubble (1889-1953) because he was the one who made the discovery that our universe was expanding. The space telescope designed to replace Hubble around 2018 is named for the late NASA administrator James Webb (1906-1992).
From an original estimate of about $400 million, by the time of launch it had cost $2.2 billion and by today has probably cost twice that amount.
launch delays, budget problems and a incorrect mirror
The Hubble telescope was the first telescope built by NASA and placed into orbit. The original launch for the telescope was delayed because of the disaster seen by the Challenger.
At this time (early 2014), the James Webb Space Telescope is scheduled to launch during October of 2018 .
The James Webb telescope is on track for a planned launch in the year 2013.
No. It's scheduled for launch in 2018.
The James Webb Space Telescope is scheduled for launch in 2018. The Webb telecope is not a direct replacement for the Hubble. The Hubble has been so reliable since its launch in April, 1990, that it's expected to function through 2014, and possibly as long as 2020.
The James Webb Space Telescope (JWST) is set to replace the Hubble Space Telescope and is scheduled to launch in 2021. The JWST will be the most powerful space telescope ever built and will study the universe in infrared wavelengths to observe objects that are difficult to see with other telescopes.
The James Webb Space Telescope (JWST) is the planned successor of the HST and the Spitzer Space Telescope (for observations in infrared). It will have a diameter of 6.5 m (the HST has 2.4 m). As of now, the launch will be in 2017 or 2018.
The James Webb telescope.
The largest telescope put into orbit is the James Webb Space Telescope (JWST). Scheduled to launch in late 2021, the JWST will have a mirror diameter of 6.5 meters, significantly larger than the Hubble Space Telescope.
The newest telescope invention is the James Webb Space Telescope, scheduled to launch in December 2021. It is designed to be the premier observatory of the next decade, serving thousands of astronomers worldwide.

Space exploration paved the way for the development of the James Webb Space Telescope by providing valuable experience in building and operating space-based observatories. Technologies and techniques developed for previous missions, such as the Hubble Space Telescope, have been applied to the design and construction of the James Webb Space Telescope. Additionally, insights gained from exploring our solar system and beyond have informed the science goals and objectives of the James Webb Space Telescope.
It is not sure yet. But NASA has predicted the date to be as between 2014 and 2015.
