'''''Zero-X''''' is a fictional Earth spacecraft that first appeared in two of [[Gerry Anderson|Gerry]] and [[Sylvia Anderson]]'s [[Supermarionation]] productions, the film ''[[Thunderbirds Are Go]]'' (1966) and the television series ''[[Captain Scarlet and the Mysterons]]''. Although publicity material for the various Supermarionation series, and the ''[[TV Century 21]]'' comic, made references to connections between the ''[[Thunderbirds (TV series)|Thunderbirds]]'' and ''Captain Scarlet'' canons, ''Zero-X'' is the only official link between the two series.<ref>{{cite AV media|url=https://www.youtube.com/watch?v=3zLDEMMDmE8|title=Zero-X: Century 21 Tech Talk |date=December 4, 2021|via=[[YouTube]]}}</ref><ref name="Burman2015">{{Cite book|title=Gerry Anderson Collectables|first1=Rob|last1=Burman|year=2015|publisher=[[Amberley Publishing]]|isbn=978-1-44564-872-9}}</ref>

==Description==
The first crewed craft to land on [[Mars]], the metallic-blue ''Zero-X'' comprises a number of detachable sections. The main body houses the chemical engines which provide the craft with the thrust required for lift-off and spaceflight. The Martian Excursion Vehicle (MEV; later renamed Martian ''Exploration'' Vehicle) is attached to the front of the main body where it serves as the craft's main control centre. During [[Atmospheric entry|atmospheric ingress or egress]], two remotely controlled "lifting bodies" (self-propelled "flying wing" [[aerofoil]]s) are attached to the main body at the front and rear. A heatproof nose cone protects the MEV during take-off and provides further aerodynamic flow to the vehicle during atmospheric ascent; it is jettisoned just before leaving the Earth's atmosphere, and is the only non-reusable part of the spacecraft.

The lifting bodies act as wings to allow the craft to operate from a runway like a conventional aeroplane, and carry multiple jet engines to reduce the amount of fuel needed for the main body's chemical engines. They separate from the main body when the craft is at a sufficiently high altitude and fly back to base; on re-entry, they rendezvous with the spacecraft and dock with it to again act as wings and provide propulsion in the atmosphere.

On reaching Mars, the MEV detaches from the main body, which is left in orbit piloted by a single astronaut, and descends towards the planet's surface. At the surface the MEV extends [[caterpillar track]]s to negotiate the rocky terrain.<ref name="TaG">''Thunderbirds Are Go'' (1966), Century 21 Cinema/United Artists.</ref>

''Zero-X'' has a total velocity of {{Convert|40|mi}} per second and acceleration of up to 15 [[G-force|g]] in emergencies. It is built by New World Aircraft Corporation, the same company that builds ''[[Thunderbirds machines#Skyship One|Skyship One]]''.<ref name="Bleathman"/>

==Appearances==
===''Thunderbirds Are Go'' (film)===
The first crewed mission to Mars ends in failure after the ''Zero-X'' is accidentally sabotaged by [[The Hood (Thunderbirds)|The Hood]], who has stowed away on the craft to photograph its wing mechanisms. The crew manage to escape and two years later a second ''Zero-X'' craft successfully reaches Mars. After touching down on the surface, the MEV crew fire on a Martian "rock snake" believing it to be a lifeless rock formation, provoking retaliation by fire-shooting rock snakes. Although the crew escape, the lifting body control systems on the MEV take damage during the confrontation, causing the ''Zero-X'' to malfunction on its return to Earth. The craft crashes into Craigsville, United States (roughly 20 miles from its launch site, the fictitious Glenn Field Spaceport). The crew survive, saved at the last moment by International Rescue.<ref name="TaG"/>

In both missions, the ''Zero-X'' carries a crew of five (including two scientists), led by Captain Paul Travers as mission commander. The crew consists of Space Captain Greg Martin (the pilot), navigator Brad Newman, astrophysicist Dr Ray Pierce and astronomer Dr Tony Grant.

===''Captain Scarlet and the Mysterons''===
Recommissioned by the Spectrum Organisation, the ''Zero-X'' returns to Mars in 2068 in search of the source of alien signals detected on Earth. The crew's hostile actions trigger a "war of nerves" with the [[Mysteron]]s. After tracing the signals to the Mysterons' city, mission leader [[Captain Black]] gives the order to fire on the outpost after mistaking the Mysterons' imaging devices for weapons and fearing the MEV is about to be attacked. Following the destruction, the crew witness the re-materialisation of the Mysteron city and the Mysterons take control of Black's mind.<ref>''Captain Scarlet and the Mysterons'' (1967), Century 21 Television/ITC, Episode 1: "[[The Mysterons]]".</ref> Black vanishes on the ''Zero-X''{{'}}s return to Glenn Field, and soon after the Mysterons began hostilities against Earth.<ref>''Captain Scarlet and the Mysterons'', Audio Adventure, MA-151: ''Introducing Captain Scarlet''.</ref>

===''Thunderbirds Are Go'' (TV series)===
The ''Zero-X'' first appears in an episode of the remake series ''[[Thunderbirds Are Go (TV series)|Thunderbirds Are Go]]'': "Signals, Part 1". During its launch, the ''Zero-X'' is stolen by The Hood for its lightspeed engines. Soon after, the engines begin to overload and threaten to create an extinction event on Earth. [[Jeff Tracy]] boards the ''Zero-X'' and attempts to take control while the Hood ejects in the only escape capsule. As Jeff attempts to take the ''Zero-X'' into space, there is a massive explosion and the craft is presumed destroyed. Eight years later, a distress signal is detected coming from the [[Oort cloud]], seemingly from Jeff. International Rescue attempts to recover the ''Zero-X'' escape capsule, believing it to be the key to understanding how Jeff survived and his current situation. After analysing footage from the capsule, they determine that the witnessed explosion was actually an aftershock of the ''Zero-X''{{'}}s engines firing at full power and that the ''Zero-X'' entered the Oort Cloud. In "The Long Reach, Part 1", remains of the ''Zero-X'' are discovered on a [[minor planet]] where Jeff has survived for eight years.

Jeff is rescued by his sons in a new ''Zero-X'' called the ''Zero-XL'', which has a very different design: it launches upright like a space rocket and incorporates ''Thunderbirds 1'', ''2'', ''3'' and ''5'' (with ''Thunderbird 4'' held in ''Thunderbird 2'''s module), all of which can now operate in space. The ''Zero-XL'' has a crew of six, namely the five Tracy brothers and [[Brains (Thunderbirds)|Brains]].

==Critical response==
According to spaceflight historian Jack Hagerty, the way in which the MEV is deployed from the mothership was inspired by both the titular spacecraft of the Andersons' earlier puppet series ''[[Fireball XL5]]'' (whose cockpit section breaks off to form a lander, ''Fireball Junior'') and the modular construction of the real-life [[Apollo spacecraft]]. He also states that the name "MEV" is based on "LEM" (Lunar Excursion Module), the original designation for the [[Apollo Lunar Module]]. Among other observations, Hagerty questions the names given for some of ''Zero-X''{{'}}s components in ''Thunderbirds Are Go'', stating that the craft's so-called nose cone "looks nothing like a cone" and that its [[lifting bodies]] do not meet the technical definition a lifting body. He also regards the brevity of the Martian landing as a plot hole: "After spending, presumably, many years and billions of dollars mounting this expedition to Mars, all they get for their effort is a couple of hours driving around on the surface." However, he calls the destruction of the ''Zero-X'' Mark II "one of the most spectacular crash sequences ever filmed".<ref name="Hagerty">{{Cite book|title=Spaceship Handbook: Rocket and Spacecraft Designs of the 20th Century: Fictional, Factual and Fantasy|last1=Hagerty|first1=Jack|last2=Rogers|first2=Jon C.|year=2001|publisher=ARA Press|location=Livermore, California|isbn=978-0-970760-40-1|pages=305–306}}</ref>

[[Stephen La Rivière]] calls ''Zero-X'' "the star of ''Thunderbirds Are Go''", praising Meddings' design and acknowledging its commercial nature: "...&nbsp;cynics would suggest that the various detachable segments (wings and nose cone) had less to do with the storyline and more to do with potential toy manufacturing!"<ref name="LaRivière"/> [[Glenn Erickson]] considers ''Zero-X'' "unwieldy" and aesthetically inferior to ''[[Thunderbirds machines#Skyship One|Skyship One]]'' in the sequel ''[[Thunderbird 6]]'' (1968).<ref>{{Cite web|url=http://www.dvdtalk.com/dvdsavant/s1295thun.html#foot%201|title=DVD Savant Review: ''Thunderbirds: International Rescue Edition''|date=17 July 2004|author=Erickson, Glenn|author-link=Glenn Erickson|work=[[DVD Talk]]|publisher=[[Internet Brands]]|access-date=23 January 2014|archive-url=https://web.archive.org/web/20121023034912/http://www.dvdtalk.com/dvdsavant/s1295thun.html|archive-date=23 October 2012|url-status=live}}</ref> Fred McNamara ranks ''Zero-X'' tenth  in a list of "greatest Supermarionation vehicles", describing it as a "fabulous slice of pulpy retro vehicle porn". He adds that "what stops it being further up the list is its jagged, boxy, rectangular design".<ref>{{Cite web|url=https://ap2hyc.com/2014/09/the-20-greatest-supermarionation-vehicles/3/|title=The 20 Greatest Supermarionation Vehicles|first=Fred|last=McNamara|date=30 September 2014|website=ap2hyc.com|publisher=A Place To Hang Your Cape|editor1-first=David|editor1-last=Molofsky|access-date=10 February 2025}}</ref>

Alasdair Wilkins of [[io9]] questions the design in that it is "not especially aerodynamic-looking". He notes the craft's protracted introduction in ''Thunderbirds Are Go'', finding the film's 10-minute opening launch sequence to be over-long: "It's pretty much the [[Alpha and Omega]] of launch sequences&nbsp;... a sequence that threatens to make ''[[2001: A Space Odyssey|2001]] [: A Space Odyssey]'' look like non-stop, thrill-a-minute action." He believes that with the attention to detail given to the various stages of the craft's assembly and take-off, these scenes constitute "launch sequence porn", elaborating: "It's a bunch of people effectively saying, 'Action? Characters? Humour? Nah, forget all that. We know what the people really want to see, and it's clearly the model-work.'"<ref name="io9">{{Cite web|url=http://io9.com/5923503/and-now-the-most-ludicrously-over+the+top-launch-sequence-porn-ever|title=And Now, The Most Ludicrously Over-The-Top Launch Sequence Porn Ever|date=4 July 2012|author=Wilkins, Alasdair|work=[[io9]]|publisher=[[Gawker Media]]|access-date=23 January 2014|archive-url=https://web.archive.org/web/20130815105917/http://io9.com/5923503/and-now-the-most-ludicrously-over+the+top-launch-sequence-porn-ever|archive-date=15 August 2013|url-status=live}}</ref> The ''[[Los Angeles Times]]'' comments that the launch is presented "with the ritual deliberation of a [[Greek Orthodox]] mass",<ref>{{Cite web|url=https://www.latimes.com/archives/la-xpm-2004-jul-23-et-lloyd23-story.html|title=Timeless with No Strings Attached|first=Robert|last=Lloyd|website=[[latimes.com]]|access-date=10 February 2025|date=23 July 2004}}</ref> while website Entertainment Focus calls the sequence "meticulous" and "foreshadowing a mechanical ballet which would define [''2001'']."<ref>{{Cite web|url=https://entertainment-focus.com/2015/06/14/thunderbirds-are-go-thunderbird-6-blu-ray-review/|title=''Thunderbirds Are Go'' & ''Thunderbird 6'' Blu-Ray Review|first=Samuel|last=Payne|date=14 June 2015|access-date=10 February 2025|website=entertainment-focus.com}}</ref> Mark Bould considers it an example of the Anderson productions' "[[Technophilia|technophilic]] model-work".<ref>{{Cite book|last1=Bould|first1=Mark|editor1-last=James|editor1-first=Edward|editor1-link=Edward James (historian)|editor2-last=Mendlesohn|editor2-first=Farah|editor2-link=Farah Mendlesohn|title=The Cambridge Companion to Science Fiction|chapter=Film and Television|year=2003|publisher=[[Cambridge University Press]]|isbn=978-0-521-01657-5}}</ref>

==Toys==
The spacecraft's introduction in ''[[Thunderbirds Are Go]]'' was accompanied by the release of a radio-controlled toy version by J. Rosenthal (Toys) Ltd. Marketed as "Five Toys in One", the product was put together from several detachable sections, similar to its assembly in the film. The remote control could also function as a [[walkie-talkie]].<ref name="Burman2015"/>
