Much media buzz this morning on launch of the James Webb Space Telescope (JWST)
The James Webb Space Telescope (JWST) is a space telescope developed by NASA with contributions from the European Space Agency (ESA) and the Canadian Space Agency (CSA). It is planned to succeed the Hubble Space Telescope as NASA’s flagship mission in astrophysics. JWST was launched on 25 December 2021 on Ariane flight VA256. It is designed to 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 providing detailed atmospheric characterization of potentially habitable exoplanets.
In ancient Egypt our Sun was revered, as both life-giver and deity. Temples and monuments were raised to connect with the sun god (Ra).
His worship increased massively in the Fifth Dynasty, when Ra became a state-deity and pharaohs had specially aligned pyramids, obelisks, and sun temples built in his honor.
In recent decades, using Big Science, we pursue our connection with the Sun beyond horizons of land & sky and into space. With spacecraft like the Parker Solar Probe, which “touches” the Sun; and the James Webb Space Telescope, which will orbit around a Sun-Earth gravitational balance point – like the ancient equipoise of heavenly throne and Earth. (In both cases relying on a sunshield to operate.)

• Washington Post > “NASA’s James Webb Space Telescope launches in French Guiana” by Joel Achenbach (December 25, 2021)
That NASA chose to forge ahead with a Christmas launch was a sign of how seriously the agency and the global scientific community take this $10 billion mission, the long-delayed successor to the Hubble Space Telescope. Officials had challenging discussions about launching on a holiday, and amid the rapid spread of the omicron variant of the coronavirus, but decided to go on the first possible day. After two technical problems and one weather delay, that turned out to be Dec. 25.
Melroy [NASA Deputy Administrator Pam Melroy] put a positive spin on it: “It’s not bad that it’s happening on Christmas Day, which should be a day of hope and inspiration.”
The separation from the final booster provided a stunning — and, for humanity, probably the final — view of the Webb. A camera on the upper stage of the rocket captured the rear end of the Webb receding, with Earth on the right side of the frame.
The predawn streets and elevated highways of Baltimore were empty, but by 6 a.m. the Space Telescope Science Institute was bustling. Some news media and scientists dropped out in recent days as the omicron variant spread, and so the hoopla was limited. Visitors were handed KN95 masks and told to take rapid coronavirus tests.
“Look farther, delve deeper and measure more precisely, and you’re bound to detect something new and wondrous,” said Kenneth Sembach, director of the telescope institute. “It is a gift to everyone who contemplates the vastness of the universe.“
“Tens of thousands of people have committed over 20 years or more on a single project,” Matt Mountain, an astronomer who is part of the team that designed the telescope, said at the telescope institute just minutes before launch Saturday. “And why? Why have they committed this time? We solve incredibly hard problems. It’s part of the human spirit. We’re curious. We explore.”

🚀 A mission of discovery …

Webb, a partnership with the European Space Agency and the Canadian Space Agency, will explore every phase of cosmic history – from within our solar system to the most distant observable galaxies in the early universe.

“The James Webb Space Telescope represents the ambition that NASA and our partners maintain to propel us forward into the future,” said NASA Administrator Bill Nelson. “The promise of Webb is not what we know we will discover; it’s what we don’t yet understand or can’t yet fathom about our universe. I can’t wait to see what it uncovers!”
I want to congratulate the team on this incredible achievement – Webb’s launch marks a significant moment not only for NASA, but for thousands of people worldwide who dedicated their time and talent to this mission over the years,” said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. “Webb’s scientific promise is now closer than it ever has been. We are poised on the edge of a truly exciting time of discovery, of things we’ve never before seen or imagined.”
NASA Headquarters oversees the mission for the agency’s Science Mission Directorate. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages Webb for the agency and oversees work on the mission performed by the Space Telescope Science Institute, Northrop Grumman, and other mission partners. In addition to Goddard, several NASA centers contributed to the project, including the agency’s Johnson Space Center in Houston, Jet Propulsion Laboratory in Southern California, Marshall Space Flight Center in Huntsville, Alabama, Ames Research Center in California’s Silicon Valley, and others.

• Space.com > “’29 days on the edge:’ What’s next for NASA’s newly launched James Webb Space Telescope” by Mike Wall (Dec 26, 2021)
“The Webb observatory has 50 major deployments … and 178 release mechanisms to deploy those 50 parts,” Webb Mission Systems Engineer Mike Menzel, of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, said in a deployment-explaining video called “29 Days on the Edge” that the agency posted in October.
“Every single one of them must work,” Menzel said. “Unfolding Webb is hands-down the most complicated spacecraft activity we’ve ever done.“
The following is a brief rundown of the big steps yet to come. (For more detail, see NASA’s Webb deployment site.) The timelines given are approximate; Webb team members have stressed that the deployment schedule is flexible, so don’t panic if the times and dates shift a bit, or if some things occur out of order.

 As visualized in the PBS NOVA documentary “Decoding the Great Pyramid” – an ancient Egyptian project which, like the James Webb Space Telescope (JWST), took ~30 years and employed 10’s of thousands of people.
• PBS > NOVA > “Decoding the Great Pyramid” – Season 46 Episode 4
New archeological evidence sheds light on the stunning engineering of the Great Pyramid of Giza.
The 6 million-ton Great Pyramid of Giza is the last surviving wonder of the ancient world. How did the Egyptians engineer the mighty pharaoh Khufu’s tomb so precisely, with none of today’s surveying and power tools?
And who were the thousands of laborers who raised the stones? Were they slaves or volunteers, and how were they housed, fed, and organized?
“Decoding the Great Pyramid” presents the latest evidence from groundbreaking archaeological research that has transformed our understanding of the ancient world’s most ambitious engineering project, revealing a “lost city” and intimate details of the lives of the laborers and officials who toiled on the vast construction.
Amazingly, French archaeologists recently found the logbook of a labor team that delivered limestone blocks to build the Great Pyramid, yielding crucial insights into the planning and logistics behind the operation.
Beyond these construction secrets, “Decoding the Great Pyramid” traces how mobilizing the colossal labor and resources invested in the monument transformed ancient Egypt, uniting a nation behind the common goal of ensuring eternity for the pharaoh and continuing prosperity for everyone in this life and the next.
