Scientific community and science-savvy public has eagerly anticipated the launch of the James Webb Space Telescope because NASA began to start plans for this in the second half of the nineties, which is the largest space telescope with Hubble Space Telescope Promises to change Recently set to be launched in spring 2020, NASA officials announced on Wednesday that the space-based observatory will now launch on March 30, 2021, and another billion dollars will be required. NASA officials say they have 80 percent confidence that they will kill that goal.
Regardless of the reassurance of authorities that “Webb is worth the wait,” the tone of Wednesday’s press conference was wolf and he did not believe things were going well with NASA’s ambitious sunflower satellite.
Thomas Zurbuchen, Associate Administrator of NASA’s Science Mission Directorate told reporters, “Do not make any mistake: I am not happy to sit here to share this story.” “We never want to do this, we always want to talk about the successes we have. If you look at our list of missions, you see how often we provide mission under cost and schedule, and we are very excited about it.
In 2003, NASA said it would launch JWST in 2011. In 2011, the whole project was re-profiled to solve those projects, in which there were very important questions about integrating telescope in the spacecraft. The budget increased from $ 2.5 billion to $ 8.7 billion, and the planned launch date reached October 2018.
Then, in September 2017, NASA announced that the space shuttle would launch in the spring of 2019. After six months, NASA pushed the launch in the spring of 2020 in March 2018. There will be estimate date of 2021. Oh, and by the way, there is no other delay in the launch date.
With launch delays, NASA announced the findings of an independent review board report whose goal is to see what went wrong and what should be done better. In response to NASA’s response to these concerns and how they will be addressed in the coming years.
The telescope, which scientists have hoped to use to see the light of light from the beginning of the universe, uses a large mirror and sun shield to observe the long wavelength of light compared to the Hubble telescope, which it uses essentially will replace. The light collecting mirror of Hubble is less than eight feet in diameter, while JWST will be more than 21 feet – a major improvement to help the researchers to gather the faint glow of light from the edges of the universe and understand our universe origins.
This huge hardware requires a strong spacecraft to carry it, and in the recent months, the report of loose screws and washers from the spacecraft during the acoustic test exposes problems with the telescope, the construction contractor Northrop Grooming is done. To highlight these problems and understand how to get the full thing in space, they will need more cash than Congress.
In the last accounting, NASA Associate Administrator Stephen Jurczyk told reporters that the new life cycle cost of JWST will now be 9.66 billion dollars to support the revised launch date. He said, “This cost includes integration and testing, launch commission, and five years of operation, in which some amazing science is going to be done.”
Everything is not good for the ZST. But NASA’s officials are trying to be optimistic, even if they believe that it is disappointing after the program and after the budget.
