During his recent talk to his employees, Musk showed future revisions of the Starship/Superheavy vehicle with longer fuel tanks, making them taller than the buildings used to assemble them. I wonder if he realizes this. The buildings will have to be modified or rebuilt, and both are expensive projects ..read more

During the final 30 seconds of the countdown and in the first three minutes after launch, it is important for the viewers to hear what is being said by mission control and the official countdown person — thjis will be especially true when astronauts are onboard. I can still hear Neil Armstrong on Apollo 11 saying "We've got a roll program" right after launch. He was so cool and calm about it. That's the sort of stuff we don't want to miss. Please do not take this as criticism. Just a suggestion for future flights. So excited to see us flying again ..read more

How can you touch the future unless you are there. At that stage it becomes the present. We can only be there together. Or can someone explain why my thinking is wrong ..read more

And it’s only 136 light years away. Don’t get me wrong I love the study of space and the tantalizing but, well let’s face it for the foreseeable future, out of reach of our ability to get to another earth like (life sustaining) planet; anywhere. Heck even the shot of sending man to Mars is now, also staring to, slip away once again ..read more

Some are "Launch Complex", others are "Space Launch Complex". Why has this happened? When did this happen? Will they all be named the same way in the future? This post is all I can find on the subject. Personally, I like "SLC" because it can be pronounced "Slick", but it is a little redundant. Which do you prefer ..read more
