The James Webb Space Telescope has finally arrived at its new home. After a Christmas launch and a month of unfolding and assembling itself in space, the new space observatory reached its final destination, a spot known as L2. …
“During the past month, JWST has achieved amazing success and is a tribute to all the folks who spent many years and even decades to ensure mission success,” said Bill Ochs, Webb project manager at NASA’s Goddard Space Flight Center. “We are now on the verge of aligning the mirrors, instrument activation and commissioning, and the start of wondrous and astonishing discoveries.”
Think about it…500 years ago there were plenty of people in abject poverty, literally not having a pot to piss in. BUT the biggest technological achievement might have been say better candles or something like that.
Now there are probably far more people, as a count, not as a percentage (but maybe percentage too) in abject poverty and yet we have the Webb telescope and computers, etc etc. To me the big question is, why are there still so many with so little despite all the advances in technology?
Probably comes back to our biological selves. The drive to stay alive, the drive to want more for tomorrow than you have today, vanity. Insecurity, fear and envy, power corrupts and greed and power feeds a thirst for gluttony, and other people simply don’t matter.
Here’s a flashback to 60’s enlightenment.
wikiThe Territorial Imperative develops the theses originally introduced in African Genesis: A Personal Investigation into the Animal Origins and Nature of Man , which was published five years earlier. In African Genesis , Ardrey posited that man originated in Africa instead of Asia, that he is driven by inherited instincts to acquire land and defend territory, and that the development of weapons was a fundamental turning point in his evolution.
The Territorial Imperative further explores these ideas with a special emphasis on man’s distinct preoccupation with the concept of territory.
It goes on to elucidate the role that inherited evolutionary instinct, particularly the so-called “territorial imperative”, plays in modern human society in phenomena such as property ownership and nation building.
On March 11, the Webb team completed the stage of alignment known as “fine phasing.” At this key stage in the commissioning of Webb’s Optical Telescope Element, every optical parameter that has been checked and tested is performing at, or above, expectations. The team also found no critical issues and no measurable contamination or blockages to Webb’s optical path. The observatory is able to successfully gather light from distant objects and deliver it to its instruments without issue.
While the purpose of this image was to focus on the bright star at the center for alignment evaluation, Webb’s optics and NIRCam are so sensitive that the galaxies and stars seen in the background show up. At this stage of Webb’s mirror alignment, known as “fine phasing,” each of the primary mirror segments have been adjusted to produce one unified image of the same star using only the NIRCam instrument. This image of the star, which is called 2MASS J17554042+6551277, uses a red filter to optimize visual contrast.
Although there are months to go before Webb ultimately delivers its new view of the cosmos, achieving this milestone means the team is confident that Webb’s first-of-its-kind optical system is working as well as possible.
