Re: The Shining City Upon a Hill
Hey, I need a breather from teaching bsm2 how to spell. Do you think you can help a brotha out and take over on Mon, Wed, and Fri? I'll catch him on the other days.
I must warn you, though, he's only spelling on a 3rd grade level. Lots of work to do.Adversity temporarily visits a strong man but stays with the weak for a lifetime.Comment

Re: The Shining City Upon a Hill
James Webb Space Telescope
The James Webb Space Telescope (JWST) is a space telescope jointly developed by NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). It is planned to succeed the Hubble Space Telescope as NASA's flagship astrophysics mission.
JWST is scheduled to be launched no earlier than 25 December 2021 during Ariane flight VA256. It will provide improved infrared resolution and sensitivity over Hubble, and will enable a broad range of investigations across the fields of astronomy and cosmology, including observing some of the most distant events and objects in the universe, such as the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exoplanets.
The primary mirror of JWST, the Optical Telescope Element, consists of 18 hexagonal mirror segments made of gold-plated beryllium which combine to create a 6.5 m (21 ft) diameter mirror—considerably larger than Hubble's 2.4 m (7 ft 10 in) mirror. Unlike the Hubble telescope, which observes in the near ultraviolet, visible, and near infrared (0.1 to 1 μm) spectra, JWST will observe in a lower frequency range, from long-wavelength visible light through mid-infrared (0.6 to 28.3 μm), which will allow it to observe high redshift objects that are too old and too distant for Hubble to observe.
The telescope must be kept very cold in order to observe in the infrared without interference, so it will be deployed in space near the Sun–Earth L2 Lagrange point, about 1.5 million kilometres (930,000 mi) from Earth (0.01 au – 3.9 times the distance of the Moon). A large sunshield made of silicon- and aluminum-coated Kapton will keep its mirror
The NASA Goddard Space Flight Center (GSFC) in Maryland is managing the development effort, and the Space Telescope Science Institute will operate Webb after launch. The prime contractor is Northrop Grumman. It is named after James E. Webb, who was the administrator of NASA from 1961 to 1968 and played an integral role in the Apollo program.
Development began in 1996 for a launch that was initially planned for 2007 and a US$500 million budget. The project had numerous delays and cost overruns, including a major redesign in 2005, a ripped sunshield during a practice deployment, a recommendation from an independent review board, the COVID-19 pandemic issues with the Ariane 5 rocket and the telescope itself, and communications issues between the telescope and the launch vehicle. Concerns among the involved scientists and engineers about the launch and deployment of the telescope have been well described.
Construction was completed in late 2016, after which an extensive testing phase began. On 21 December 2021, NASA announced that JWST is scheduled to launch at 12:20 UTC (07:20 am EST/usa) on 25 December 2021 by an Ariane 5 launch vehicle from Kourou, French Guiana, on the northeastern coast of South America.
... this amazing new space telescope allows humans to see 100 times farther into space with much greater detail than the revered Hubble telescope.
... this incredible telescope is scheduled to launch Christmas morning! What a fantastic gift to mankind and science!Comment

Re: The Shining City Upon a Hill
NASA Budget- $22.6 billion
Canada Space Agency Budget - $421.1 million
Who paid for the James Webb Telescope?
NASA's lifetime cost for the project is expected to be US$9.7 billion, of which US$8.8 billion was spent on spacecraft design and development and US$861 million is planned to support five years of mission operations.
Canada has contributed a scientific instrument and a guidance sensor.

President Biden has been able to muscle through the most federal judges in his first year in office in nearly 40 years and how important the diversity of the nominees has been compared to Trump
