Astronomers Want to Build A Forty Foot Space Telescope to Find theNext Earth

"With Pluto millions of miles behind us and construction of the James Webb Space
Telescope moving swiftly along, astronomers are already thinking about the Next
Big Mission. At the top of their wish list? A forty foot-wide orbital telescope
that'll search for proof of life beyond Earth."

"construction of the James Webb Space Telescope moving swiftly along"
That's kind of rich/revisionist isn't it?

It is not a question of half full or empty - the glass has a leak.
The real question is "Can it be patched?"
these opinions are mine, all mine; HPE might not want them anyway...

The NASA manned space program keeps saying Orion will take astronauts to
Mars and very few in the media challenge them on this. So, I suppose,
the unmanned space program feels free to stretch the truth too.

than advanced airbreathing engines, and so are the tanks to put it in
and the extra thrust to carry it." - Henry Spencer

I suppose it would be somewhat like saying that the taxi I took
too/from the airport took me to where I flew

probably better results by combining the data electronically from a group of smaller satellites some distance apart, making them equivalent to a much larger satellite.

Doesn't work quite as well as you might think, especially in the optical
range.

You really ultimately want the biggest bucket you can build.

And honestly, 40' wide... I think we can do better.
If we're going to build the next generation, we should go big or stay home.

We're building telescopes here on Earth with 30M or large diameters.
James Web is 6.5M.

the big hassle is launching something that large

would the reflector fold up?

Yes, Just like the James Webb is going to.
