I believe what you're seeing is the concept of the Document Object Model, where basically "text nodes" are anything that's not an element, including everything between <script> tags etc. One easy workaround is to clobber all the tags you don't want:

use Mojo::Base -strict;
use open qw/:std :utf8/;
use Mojo::UserAgent;

my $ua = Mojo::UserAgent->new( max_redirects => 3 );
my $res = $ua->get('http://www.spacex.com/webcast')->result;
die $res->message unless $res->is_success;

my $dom = $res->dom;
$dom->find('script, style')->map('remove');
my $text = $dom->at('body')->all_text;
1 while $text =~ s/\s{2,}/ /g;
say $text;
