Haven’t I Seen... ?:
• The type 2 robot seen at the beginning has the banding Lizzie and Katy had (TR) on its body but not on its head.
• Marog is Dr Duncan with dark hair and a monocle.
• Brig is Berridge (MM) with an eyepatch.
• The third member is Miga’s aide (UA).
• And we get a return visit to Phobos.

Take A Break:
• Having been told by Dart he has made a detour to Phobos, Raeburn tells Marla to inform the Martian President but "Don't let him speak to me!"

Astro Viewer Working:
• Curiously (or perhaps ironically), Marog’s men are tricked with the same ruse used to get the Galasphere to land on Phobos in the first place - illness!
• The listings for this story (see below) state Marog is a Martian, but he lacks their characteristic appearance.

Hoorah!:
• The crew of Galasphere 347 prepared to nearly sacrifice their lives, so as not to alert Marog to their escape and sabotage attempts.

Boo!:
• Isn’t threatening to destroy a city a little excessive, particularly if you’re trying to get a pardon for criminal activities ?
• We only see three criminals but Brig says ‘everyone was killed’ to Marog when it seems quite clear that only the third and unnamed member was present in the hydrogen bomb chamber.

Listings
• London, May 28th 1964:
On their way to Mars with a cargo of hydrogen and oxygen, required for an irrigation project, Dart and his galasphere are captured by a Martian renegade who has sinister palns for the gas.
• Tyne Tees, June 8th 1964:
A great deal of Mars is desert and the Martian President asks Raeburn to find a way of bringing water to it, since irrigation is too costly. Professor Haggarty has brought water to the Sahara by means of an ingenious method involving the use of oxygen from Earth and hydrogen clouds in the uper atmosphere.
Raeburn decides to use the same method fro Mars, but since there is no hydrogen in the Martian atmosphere, they have to take both hydrogen and oxygen to Mars.
Dart is detailed to do this and en route his Galasphere and cargo is captured by a Martian convict who has set up a satellite and is in process of building an atom bomb. By capturing Dart's cargo he is now able to build a hydrogen bomb and threatens to destroy the Martian capital unless he is given what he wants.


Ready To Lift ?:
A very standard plot, almost identical to that of The Sands Of Death.
