The Nostromo’s Science Officer, Ash, said the planet had ‘Rock, lava base’ (2122). The Company woman at the inquest of Ellen Ripley called LV-426 a ‘rock’ (2179). So it’s obviously better to go with Ash’s scientific analysis. However not being a geologist, I have no idea what ‘rock, lava base’ exactly means. To me it says ‘it’s a rock’. However a lot of geyser activity was witnessed by the Nostromo’s search party in 2122, during the walk to the Derelict. This geyser activity abated around local sunrise. It was not evident at all in 2179, so perhaps the atmosphere processing has some effect on it (unlikely but possible). In 2122 the atmosphere was described as ‘primordial [with] inert nitrogen, a high concentration of carbon dioxide crystals, methane and trace elements’. It was not breathable to humans, however after 20 years of atmosphere processing it became breathable. The wild dust storms witnessed by the crew of the Nostromo, were still evident in 2179 despite the atmosphere processing.
To get more technical, ‘the crust is made up from aluminum silicates, though there is plenty of evidence of magnesium silicate intrusion, manifest on the surface as basalt, rhyolite and microgranite lava flows. Despite the ample evidence of activity in the planetoids core, there is no discernable volcanism or tectonic activity present, which would be consistent with a tidally locked body.’ Having said all that, there was some volcanic activity in the recent past, as the Derelict spacecraft investigated by crew of the Nostromo in 2122 was heavily damaged and partially buried under a lava flow when it was re-discovered by the Jorden family in 2179.
Points of interest:
Hadley’s Hope Terraforming Colony – Established by Weyland Yutani and the ECA around 2157, it took the colonists nearly 20 years to make the air just breathable to humans. The colony consisted of three levels –
Sub Basement (below ground) Which was predominantly used for maintenance and storage.
Level 1 (ground level) Mainly living quarters and colonists services such as the Hadley Bar & Grill.
Level 2 (above ground) Mainly Colonial Operations, offices, medical and science lab.
There is also another level beneath the Sub Basement, but is only used as a maintenance crawlspace and reservoir for the colony’s water supply.
The colony was commanded by Al Simpson along with Operations Assistant Lydecker at the time of it’s destruction in 2179. Russ Jorden and his family accidently introduced an Alien organism into the colony which subsequently multiplied and wiped out the population of 157. The only survivor was Jorden’s daughter Rebecca.
The Atmosphere Processor is located approximately one mile from the colony proper, and consists of some 30+ levels, plus 5 levels below ground. Points of reference include
– Dock 7 (gates 27 and 28) which is where the Bishop synthetic dropped off Ellen Ripley in her rescue attempt of Rebecca ‘Newt’ Jorden.
– Sub Level 3 which is part of the Alien hive where the marines of 2nd Battalion 9th Regiment discovered the remains of the colonists, and subsequently lost 6 of their number when the Aliens atacked.
– Sub Level 4 which is where Ellen Ripley and Newt Jorden first encountered the Alien Queen.
All that remains of Hadley’s Hope is a large crater thanks to the atmosphere processor going critical.
The Ilium Range:
Located approximately 20-30 km* in an easterly direction of Hadley’s Hope lies an unremarkable mountain range, that has been volcanically active during the mid 22nd century.
Just east again of the Ilium Range, on a high plateau, is a gigantic Derelict spacecraft of unknown origin, that was investigated by the crew of the USCSS Nostromo in 2122 and again by the Jorden family in 2179. Discovered on board was a fossilised Alien organism (type unknown) and thousands of Alien ‘eggs’. One of these ‘eggs’ infected Exec Officer G.W. Kane in 2122 and another infected Russ Jorden in 2179 with xenomorph spore. The Derelict was destroyed after Hadley’s Hope was obliterated in 2179.
USCSS Nostromo LZ:
Approximately 2000 metres south west of where the Derelict once stood, is the spot where the Nostromo landed in 2122. Due to the high winds on Acheron, there is now no trace of where the Nostromo set down.
* – The 20-30 km distance from the colony to the Ilium Range is based on the fact that Bishop said the blast radius from the exploding AP station was about 30 km. The Alien Resurrection novel says the Derelict was destroyed in the AP station explosion, so logically, the Derelict must’ve been within the blast radius.
Fiorina 161 is a small planet orbiting an insignificant binary star in the Neroid Sector of the Outer Veil. It orbits just inside the outer edge of the system’s life zone, and shares the system with at least one other planet. A planet of dark seas and high winds, night temperatures are in the vicinity of minus 40 degrees centigrade. It’s rotation is approximately 10 days.
The major indigenous life form on the planet is a microscopic parasitic carnivorous arthropods, simply called ‘lice’ by the local populous. They will infest any other life form with hair, as they have an appetite for keratin (though they aren’t attracted to fingernails). Any lotions strong enough to combat the parasites caused skin blistering. The lice themselves causing itching and major skin irritation.
Weyland-Yutani set up a large (approx 10 miles square) mineral ore mine and refinery on Fiorina which was subsequently converted into a Class C maximum security male work correctional facility when the last of the ore (mainly platinum) was refined and shipped off-world. Weyland-Yutani leased the operational part of the facility to the government for the prison, effectively leaving a custodial presence – 22 prisoners, 2 warders, and 1 medical officer. They now produce lead sheets for toxic wste containers. The inhabitants of the facility dealt with the lice by shaving off all their body hair.
After the bio-weapon incident of 2179, the facility was shut down permanently and the remaining prisoner was re-assigned.

LV-223 is one of the three moons of the gas giant Calpamos orbiting Zeta 2 Reticuli. Its sister moon is Acheron LV-426.
It was the site of an Engineer bio-weapons facility for millennia before its inhabitants were wiped out, presumably when one of the weapons got loose, sometime between the early first century CE and late second century CE. Five of the Engineer’s ‘temples’ were charted by USCSS Prometheus in 2093 and it’s believed each was connected by a subterranean tunnel to a Juggernaut spacecraft. One of the ships lies crashed on the planet after being rammed down by the Prometheus. A second ship was taken by Dr Elizabeth Shaw and the synthetic David and flown to the uncharted world 16EG14 in 2094.

The rotation is based on dialogue from Janek saying there’s only 6 hours of daylight remaining, implying that the time from sunrise to sunset is much longer. However, some key shots just before the silica storm show sunlight coming from different directions, making it impossible to determine the time. It appears to be nearing sunset in some shots when the light is coming from Prometheus port side. The sun rises behind Prometheus, which is indicated to be west when Janek speaks to Millburn and Fifield about the lifeform ping (west of their location). Daylight times could also be confused due to the presence of the gas giant as well as the planet’s rotation.
