Apollo 13 landing site
« on: September 14, 2021, 03:15:34 AM »
Has anybody got a screenshot from an astronomy app or similar showing that the planned Apollo 13 landing site at Fra Mauro was on the dayside of the terminator at the planned landing time? I want to debunk the hoaxnut myth that it would have still been in darkness.

Here you go. This is terminator at touchdown.

The tool to use is the Virtual Moon Atlas which can use 60 metre resolution maps from LRO WAC as well as LOLA, LOPAM and Chang'e.

Stellarium is another great tool which will also give you a view on the lunar surface so you can check the Sun's location in the Lunar sky at the time.

Something that will be clear enough in a 720p Youtube video

That is brilliant. Many thanks indeed.
Have you got a YT channel or blog I can give a shout-out to in my video?

No worries, glad to help.
I have a YT channel, but it's not worth linking to! ;D

I know the usual suspects are claiming NASA pulled its original press releases once the 'error' was uncovered. I guess they got Walter Kronkite to re-voice this:

I'll make sure to put this in my debunk too.

Couple of newspaper front pages detailing the timeline up to descent orbit insertion - weirdly, they match what's in the press kit. It's almost as if NASA issued them to the press so they could report them to the public...

There are bound to be actual newspapers from around launch somewhere - still looking for one that gives a "due to land at..."!

Then there'll be the actual published flight plans, cuff check lists and so on - that's a lot of document shredding and re-printing!

it's faint, but it's visible:

Nice map but where was the planned landing site?

The red dot indicates the planned landing site.

Ah I didn't enlarge the map and couldn't see the red dot.
Thanks
