So this happened yesterday! 💕 Looking forward to sharing the rest of life with @ian_r_prather! #yes #proposal #love #engaged #together https://www.instagram.com/p/BoHfWGEhbwb/?utm_source=ig_tumblr_share&igshid=m1uxk9a88qzy

I was inspired by a restaurant we love to go to when we tried an appetizer of pork belly bites with a cherry glaze. I made a keto version of it after researching and combining ideas and methods to make this the way I imagined it from the restaurant's perspective. It turned out amazing...and the pork belly is even fantastic on its own. So this was our first meal of the day, and it was soooo good!!! 😊 As a bonus, pork belly (where we are) is only $5.49/lb. 👍 #ketolife #keto #meat #ilovemeat #healthy #yummy https://www.instagram.com/p/BnSYa6KhPs0/?utm_source=ig_tumblr_share&igshid=1njv7mxjyowug

My granddaughter's dance studio tagged me in their post of her at dance last week. Love this pic of her on the silks! 💕 #talentedgirl #silks #dance #performer #loveher #beautiful https://www.instagram.com/p/Bm1kfCwAVkH/?utm_source=ig_tumblr_share&igshid=11kzkvfr6m4ev

Made my keto lasagna for dinner a couple nights ago, and it got me through family dinner and two days of lunch at work even in the midst of the kids getting into it in the night! So yummy!! 😋 #ketogenic #keto #ketolife #healthyfat #healthy #yummy https://www.instagram.com/p/BmgIlaZhboY/?utm_source=ig_tumblr_share&igshid=70ryaubwae1g

I snagged this first pic from her own post, and I took the other pics a couple days ago at Circus Camp. This girl loves dance with all she is; and she's added Lyra hoop, silks and tight rope walking (yes, you read that right) which she no longer needs guides for to her repertoire! She is an amazing talent, though I may be a bit partial as her GiGi! I love watching her grow and become such a wonderful artist! #dance #loveher #granddaughter

Nice surprise from my friend in Photo/TV at NASA who gave me a new lanyard he got at a photo technology event where RED Digital Cinema was featuring some of their amazing camera hardware! RED cameras have been a project for me at NASA for a few years in which we've now flown 4 of their cameras; so this is extra special to me, taking my day #abovetheclouds! I think my NASA pin also adds an extra level of awesome to this gift! 📽🚀 #nasa #space #science #iss #spacestation #reddigitalcinema #reddigitalcamera #redcamera #redepic #reddragon #redweapon

The Beauty of Webb Telescope’s Mirrors

The James Webb Space Telescope’s gold-plated, beryllium mirrors are beautiful feats of engineering. From the 18 hexagonal primary mirror segments, to the perfectly circular secondary mirror, and even the slightly trapezoidal tertiary mirror and the intricate fine-steering mirror, each reflector went through a rigorous refinement process before it was ready to mount on the telescope. This flawless formation process was critical for Webb, which will use the mirrors to peer far back in time to capture the light from the first stars and galaxies. 

The James Webb Space Telescope, or Webb, is our upcoming infrared space observatory, which will launch in 2019. It will spy the first luminous objects that formed in the universe and shed light on how galaxies evolve, how stars and planetary systems are born, and how life could form on other planets.  

A polish and shine that would make your car jealous

All of the Webb telescope’s mirrors were polished to accuracies of approximately one millionth of an inch. The beryllium mirrors were polished at room temperature with slight imperfections, so as they change shape ever so slightly while cooling to their operating temperatures in space, they achieve their perfect shape for operations.

The Midas touch

Engineers used a process called vacuum vapor deposition to coat Webb’s mirrors with an ultra-thin layer of gold. Each mirror only required about 3 grams (about 0.11 ounces) of gold. It only took about a golf ball-sized amount of gold to paint the entire main mirror!

Before the deposition process began, engineers had to be absolutely sure the mirror surfaces were free from contaminants. 

The engineers thoroughly wiped down each mirror, then checked it in low light conditions to ensure there was no residue on the surface.

Inside the vacuum deposition chamber, the tiny amount of gold is turned into a vapor and deposited to cover the entire surface of each mirror.

Primary, secondary, and tertiary mirrors, oh my!

Each of Webb’s primary mirror segments is hexagonally shaped. The entire 6.5-meter (21.3-foot) primary mirror is slightly curved (concave), so each approximately 1.3-meter (4.3-foot) piece has a slight curve to it.

Those curves repeat themselves among the segments, so there are only three different shapes — 6 of each type. In the image below, those different shapes are labeled as A, B, and C.

Webb’s perfectly circular secondary mirror captures light from the 18 primary mirror segments and relays those images to the telescope���s tertiary mirror.

The secondary mirror is convex, so the reflective surface bulges toward a light source. It looks much like a curved mirror that you see on the wall near the exit of a parking garage that lets motorists see around a corner.

Webb’s trapezoidal tertiary mirror captures light from the secondary mirror and relays it to the fine-steering mirror and science instruments. The tertiary mirror sits at the center of the telescope’s primary mirror. The tertiary mirror is the only fixed mirror in the system — all of the other mirrors align to it.

All of the mirrors working together will provide Webb with the most advanced infrared vision of any space observatory we’ve ever launched!

Who is the fairest of them all?

The beauty of Webb’s primary mirror was apparent as it rotated past a cleanroom observation window at our Goddard Space Flight Center in Greenbelt, Maryland. If you look closely in the reflection, you will see none other than James Webb Space Telescope senior project scientist and Nobel Laureate John Mather!
