It's moving day for the Robinson party when Nerim the space miner cracks the planet's core while blasting for cosmonium, quintessence of the living force that's far more precious than diamonds. Despite Nerim's assurances to the contrary, the planet is doomed, forcing him to gamble his precious cosmonium with covetous Dr. Smith for a working thruster control to get off before it explodes.

It logically follows that Mr. Nerim's actions must cause the genocide of the society from Lost in Space: The Lost Civilization including Will's friend the little Princess, yet none of the Jupiter 2 crew mention or seem the least bit disturbed by this horrifying fact. See more »


Dr. Zachary Smith: My dear sir, at the risk of appearing curious, may I ask what you were blasting FOR?
Nerim: Cosmonium.
Dr. Zachary Smith: Cosmonium? Cos... I don't believe I've ever heard of it. I don't suppose it's very... precious?
Nerim: Well, it is, if you know HOW to get it and what to do with it.

Here is a very solid season opener, rated 6.5..
26 September 2012 | by (United States) – See all my reviews

Okay..I am back.

Here we go..the blessed and glorious (in all-living color) Season Two kick-off episode. Many will put this one as the 'weakest' of the season openers (if you will) but not me. Yes..I rank this one ahead of "Condemned Of Space. And why wouldn't I? I boast of how much I love colored Season Two, and although it may not be as overall as 'exciting' as "Condemned Of Space," "Blast Off Into Space" gets my vote as a few notches higher. Why, you might ask. Well, the reasons are obvious. Being so utterly close to and recently removed from lovable B&W Season One, it still has a Season One feel to it. They are still on the lost and forsaken and barren planet. The kids (Penny and William in particular) are still quite young. Dr. Smith is not overly 'over the top' with an "effeminate" (to coin Robert's phrase) characterization, like he is in later Season Three episodes..and the story is very solid.

Basically, this is still an episode to love (if you are a big B&W fan), of course. Just like "Condemned Of Space" and "Visit To A Hostile Planet," there is really nothing not to like so far in the anniversary season. All three are pretty much devoid of pitfalls and drawbacks.

I have seen fans share their dislike for Mr. Nerim and his mule, for being too 'earth-like,' or something. Who cares? Maybe it is because I love a good western-style episode, or because I love Strother Martin's appearances in THE BIG VALLEY (or whatever else), but I like him and his characterization of the old miner just fine. His donkey was just an added interest. Actually, Mr. Nerim was an extremely likable old chum. It is odd and very rare, however, that the main guest star was done and gone pretty much at the midpoint of the story.

The new background incidental music guest scores from Leith Stevens were not exactly 'stellar' or a big favorite of mine, but it (the music) works just fine for the story. It was a big plus to bring on a guest composer for such a huge occasion as a season premier..especially the first colored episode premier. This was big!

How big was it? Well, "Blast Off Into Space" is my #7-ranked episode on the season..slightly above "Condemned Of Space," yet slightly below "Visit To A Hostile Planet." Wait! Who is trying to compare episodes from 'across the seasons?' That is never a good idea, and never an easy thing to do. :-]

Here is a very interesting bit of trivia you may not know. This is the one and the only episode where the guest star's character's name is listed in the opening credits, instead of saying "Guest Star." What I mean is, instead of reading "Guest Star Strother Martin," the opening credit reads "Strother Martin as Nerim." This is totally a one-of-a-kind occurrence.

So far, the illustrious Peter Packer has helmed all three anniversary episodes. That streak ends tomorrow..
