How Close Are We to Launching the James Webb Space Telescope?

The James Webb Space Telescope will allow us to see further into space than ever before, and its discoveries are expected to revolutionize astronomy. So, how close are we to finally launching it?

Later this year, the Webb telescope will become a fully integrated observatory for the first time through integration of the SCE to the Optical Telescope Element/Integrated Science Instrument Module." How the Webb Telescope Will Explore Mars https://www.nasa.gov/feature/how-the-webb-telescope-will-explore-mars/ "When NASA's James Webb Space Telescope, launching in 2021, reaches its destination a million miles from Earth, it will be able to see the whole disk of Mars every two years. If a global dust storm envelops the Red Planet at a time when Webb could see it, the powerful space telescope could gather information about the storm, adding to data from spacecraft on or close to the planet's surface." Building James Webb: the biggest, boldest, riskiest space telescope https://www.sciencemag.org/news/2016/02/building-james-webb-biggest-boldest-riskiest-space-telescope "Webb is the biggest, most complex, and most expensive science mission that NASA has ever attempted, and expectations among astronomers and the public are huge. Webb will have 100 times the sensitivity of the Hubble Space Telescope." ____________________ How close are we to colonizing the moon, mapping
