Updated Galileo + Probe + HGA closed model

Post #1by JackHiggins » 13.10.2003, 20:07

Hey all!

My first new addon for ages... :D It's not really brand new though, just an update to previous ones.

Most of you will know that when Galileo tried to deploy it's High Gain Antenna (HGA) it never fully opened, and that was the cause of much concern at NASA before the probe ever got to Jupiter.

However, between it's launch in late 1989 & the first deployment attempt in April 1991, this problem was not known about, because the HGA was closed the whole time. On the 11th April 1991, the first attempt to open it was made, and that's when it partially stuck.

This model shows the period between deployment & the 11th April '91, when the HGA was closed. (Basically it's the old "Galileo + Probe" model, but with the "Galileo + IUS" style HGA.)


To view this model, you'll also need to download the ssc file update, which i've made available on my site too. This just replaces the old solarsys.ssc patch. If you had this before, you can delete it now... This stuff is all explained in the readme file anyway!

So... To download it, it's number 19 on the spacecraft page, at http://homepage.eircom.net/~jackcelestia/ . The new ones are called "Galileo ssc patch" and "Galileo + Probe + HGA closed"

But check out a few screenshots first...! :D

Thanks for this Jack

I think it might be safe to say that you have created the first piece of genuine model animation in Celestia ? That mesh style HGA tries to open at the stroke of midnight (GMT) on 10th/11th April 1991, but ends up sticking in its mainly closed position, and now all of us have the chance to witness this historic event!

I take it that you are keeping the 'galileo dies' part of the mission seperate from this?
