I'm not sure if anyone has yet estimated the current expected, and I don't
have the time to attempt an estimate here, but I do know there are those
kind of details in a quite recent issue of the EOS newsletter.

How does the heat generated by the sun get to us???

"Thankyouthankyouthankyou. It's great to be here. Say, do you know
how many elephants can fit in a Soyuz? Three! But they have to be
REALLY GOOD FRIENDS! And now, on with the Weekly Reminders!"
This notice will be posted weekly in sci.space, sci.astro, and
sci.space.shuttle.
The Frequently Asked Questions (FAQ) list for sci.space and sci.astro is
posted approximately monthly. It also covers many questions that come up on
sci.space.shuttle (for shuttle launch dates, see below).
The FAQ is posted with a long expiration date, so a copy may be in your
news spool directory (look at old articles in sci.space). If not, here are
two ways to get a copy without waiting for the next posting:
(1) If your machine is on the Internet, it can be obtained by anonymous
FTP from the SPACE archive at ames.arc.nasa.gov (128.102.18.3) in directory
pub/SPACE/FAQ.
(2) Otherwise, send email to 'archive-server@ames.arc.nasa.gov'
containing the single line:
help
The archive server will return directions on how to use it. To get an
index of files in the FAQ directory, send email containing the lines:
send space FAQ/Index
send space FAQ/faq1
Use these files as a guide to which other files to retrieve to answer
your questions.
Shuttle launch dates are posted by Ken Hollis periodically in
sci.space.shuttle. A copy of his manifest is now available in the Ames
archive in pub/SPACE/FAQ/manifest and may be requested from the email
archive-server with 'send space FAQ/manifest'. Please get this document
instead of posting requests for information on launches and landings.
Do not post followups to this article; respond to the author.
"Thanks, ya been a great audience!"
