The Webb Space Telescope for you Techies

The Webb Telescope blow by blow. Amazing accomplishment so far -

Quite the operation, great share.
I get a kick out of the crowd that complains about the money spent on these space exploration programs, they are often the folks that would support the bottomless pit social engineering programs. Which ones actually produce tangible results? We all know the answer but dare not bring it up.
Carpe Diem

Here's a cool site with lots of info:

Here's some more cool info about the mirrors:

Just one small portion of that:
"
Achieving A Single Perfect Focus- Actuators
Once in space, getting these mirrors to focus correctly on faraway galaxies is another challenge. Actuators, or tiny mechanical motors, provide the answer to achieving a single perfect focus. The primary mirror segments and secondary mirror are moved by six actuators that are attached to the back of each mirror piece. The primary mirror segments also have an additional actuator at its center that adjusts its curvature. The telescope's tertiary mirror remains stationary.

Lee Feinberg, Webb Optical Telescope Element Manager at NASA Goddard explains, "Aligning the primary mirror segments as though they are a single large mirror means each mirror is aligned to 1/10,000th the thickness of a human hair. What's even more amazing is that the engineers and scientists working on the Webb telescope literally had to invent how to do this."

100%. We do not spend near enough on space exploration and research. End entitlements and use the money to advance mankind.

let’s get back to over 3% of GDP for NASA.
