Havent I Seen... ?:
The gamewarden was one of the Martian colonists in The Slaves Of Neptune with a moustache.
Gabbler says Zeffers device looks like the birdsong machine used to teach him to talk. (It doesnt, incidentally.)
Take A Break:
Dart tells the gamewarden he has hoverjets and the gamewarden replies "Good, let's get them." On the video release, the fade out is retained but on the DVD release it has been edited out.
Astro Viewer Working:
Professor Zeffer occasionally wears glasses.
The star on Huskys uniform disappears when he is invisible. Maybe its organic too.
This episode is sometimes referred to The Invsible Martian, no documentary evidence supporting the alternate title has been found.
Hoorah!:
Husky being invisible - a puppet suit with no hands or head - is eerily effective.
The condition The Floats anticipates well the problems faced by real astronauts in microgravity environments.
While we know Husky would never be killed, there is an oh no moment when Haggarty suggests the only way to make him reappear is to make his molecules lifeless.
There also a reference to a television satellite, anticipating satellite TV by more than twenty years.

Boo!:
The Galasphere 024 launch is used.
The Martian President seems to be the same puppet seen in The Wandering Asteroid but speaks with a typically accented voice this time.
Where exactly does the invisible Husky sit on Darts hoverjet?

London, December 5th 1963:
Husky, visiting Mars with Larry Dart, becomes invisible through an accident. This proves of great value, but Husky does not want to be invisible for ever, and there seems to be no prospect of him returning to his normal state.
Brahms & List
It is rumoured the alternative title of The Invisible Martian came from an Australian listing for the episode.
Ready To Lift ?:
A somewhat whimsical and humourous episode in theme, and the Aba seems suitably alien - until it laughs.
