Technology Development

In 2016, scientists at Goddard Space Flight Center (GSFC) produced mirrors with the highest reflectance ever reported in the farultraviolet (FUV) spectral range (100-200 nm). To develop these mirrors, the team developed a new three-step physical vapor deposition process to coat aluminum mirrors with protective magnesium fluoride (MgF²) or lithium fluoride (LiF) films to protect the aluminum from naturally occurring oxidation and boost its reflectance performance in the FUV.

Impact 

These high-reflectance coatings will enable new types of instruments (particularly in the FUV spectral region) that can provide scientists with knowledge that could impact society. For example, NASA is developing a new set of Heliophysics satellites—including the Ionospheric Connection Explorer (ICON) and the Globalscale Observations of the Limb and Disk (GOLD)—that will employ these coatings. ICON and GOLD will have the higher sensitivity required to collect data about the forces at play in the near-space environment of Earth’s upper atmosphere. These atmospheric regions are very sensitive to space weather events and space climate, and monitoring them will help scientists understand the interactions between Earth’s ionosphere and solar winds that can drive extreme weather systems. In addition, these observations will enable researchers to understand disturbances that can lead to severe interference with communications and Global Positioning System (GPS) signals.

Status and Future Plans 

In 2016, NASA fully validated these protective coatings to ensure that they provide over 90% reflectance in the 133.6-154.5 nm range for the ICON and GOLD projects. The team is also investigating additional new types of fluoride coatings that can be used to protect aluminum to meet requirements of next-generation NASA observatories, such as the Large Ultraviolet/Optical/ Infrared (LUVOIR) surveyor.

Sponsoring Organization 

SMD previously supported development of these new coating technologies through an SAT grant and currently sponsors this work via the APRA program. The technology lead is Manuel Quijada at NASA GSFC.

Bidding at [community profile] fandomlovespuertorico closes today (thanks to [personal profile] sholio for the heads-up).
Monday, October 23rd, 2017 02:25 am
Last spring there were plans to run a gen fanworks exchange through [livejournal.com profile] collarcorner, which I then flaked out on running, but it has found renewed life with the lovely [personal profile] sapphire2309 and [livejournal.com profile] nywcgirl as the mods. There is a poll over on LJ if you're interested, to determine dates and fanwork types. It'll be run through the LJ comm, but people without LJ accounts can still participate anonymously if you like, with a mod posting your assignment for you.

[community profile] fandomlovespuertorico benefit auctions end today at 6pm eastern time. If you want to bid on anything, last chance!

I think I had some other things to mention, but now I've forgotten them ...

It's time to sign up for the November WIP challenge!

Some people join the challenge midmonth, or comment on check-in posts without signing up, which is fine -- I'm glad there's a way for the challenge to be useful in a variety of ways.

But for those of you who find the commitment of signing up useful, please leave a comment with the below information.

Signups will be open until the end of October.



  • Level of challenge: 1 chapter, 1000 words, 1 fic finished, whatever you like
  • Fandom(s) involved: if you know at this point
  • What you're looking for from the challenge: this could be as vague or specific as you like: someone to be accountable to, someone to remind you to write, someone to bounce ideas off, etc.
  • What you could offer other participants yourself: ditto!
  • How people should contact you: DW message, e-mail, IM etc.
  • Time zone: useful for seeing who might be up for a writing session at a time convenient to you


Copypaste below:



I couldn't continue to run this challenge without assistance with the daily check-in posts. Many thanks to everyone who's helped with the check-ins before!

Please let me know if you'd be interested in helping out. A week per person would be ideal (I usually assign weeks running Sunday-Saturday just for consistency). I'm happy to help come up with suggestions for discussion topics (& Friday or Saturday is usually the general chat/snippet/beta-seeking etc. post).

(& if you've completed a fic through the challenge, don't forget our collection on AO3! If you need AO3 invites, let me know.)

"I know that there are people who think that this is odd.  They take their comfort other ways -- from liquor or from God.  Now sometimes prayer can call me or a drink helps get me through,  But nothing is so healing as the days I spend with you."   -- from "My Thousand Closest Friends" (1991) by Naomi Pardue

Politico: Young subscribers flock to old media

What's particularly fascinating is the way in which it's directly correlated with people wanting to support news organizations as a way to resist Trump:

“The big boost we saw in subscriptions in the U.S.,” Newman said, “is driven by people on the left and younger people are more likely to be on the left. That is really a lot of what’s driving it: young people who don’t like Trump who subscribe to news organizations that they see as being a bulwark against him.”

Keep up the good work!

which I have been hiding from for nearly a year owing to its close temporal (and partially causal) association with my major mood dip at the start of the year.

Because I am in no way MASSIVELY AVOIDANT or anything, no why would you think that.

I will accept praise and validation.

"Don't push that button! Jesus, Ron!
 Don't push that button! Or we're gone.
 I know you hate the 'Russkies,' and wish they'd go away,
 But dodging falling A-bombs would just ruin our whole day!
 Don't push that button! Jesus, Ron!
 Don't push that button! Or we're gone.
 A war would be the worst thing our world had yet endured.
 Destruction would be mutu'lly assured."

No real name. This was an instafilk based on a FB post

TTTO "People" by Barbra Streisand
People
People who hate people
Are the horrib'lest people in the world,
They're children
Whiny, bratty children
And they're letting their trollish side
Make fun of and deride
Acting more like cavemen
Than children.
Haters are most annoying people,
They're the angriest people in the world
They're on Twitter
On Facebook and on Twitter
They're missing part of their soul
So they attack and they troll
They'll use ALL CAPS and swear
So there is a person
Who hates people
People who hate people
Are the angriest people
In the world

The original song, for comparison, is on Youtube

Hi,

I have been using OpenID in order to comment on LJ communities as I don't want to have an LJ account for obvious reasons.

I used to be able to log in just fine and post comments and create posts etc. But I recently got a new computer and went to log in and comment and it told me I needed to validate my email address. So I clicked through to a link and then clicked the link that was in the email that LiveJournal sent to my email address.

When I click this link in the validation email, it takes me to a page titled:

"Please, verify that you are human"
When you submit the form an invisible reCAPTCHA check will be performed.
You must follow the Privacy Policy and Google Terms of use.

Then there's a continue button to click on. I click the page and it looks like it's doing something, but it takes me back to the same page again and I remain unverified and now unable to comment or post on any communities.

Any ideas as to how I can get LJ to actually verify the email address for my OpenID account? Thanks!
