Space Cadet: Horror on the Lunar Gateway

Lunar Gateway is the access portal to Lunar Operations. Unfortunately all communications with Lunar Gateway have been lost just as Billionaire and Space Explorer Randolf Mush is stopping off from a visit to the Moon.
As your ship approaches you notice that the ISS-Lunar Gateway transfer vehicle Ares is in a semideployed condition at the end of the Canada Arm, and its docking point (Area 5) is exposed to space- fully vented.

Investigating Lunar Gateway
1- The main core is apparently cold and devoid of life. Investigation of the storage cabinets in this area reveals two space suits are missing. There is a fault in an electrical box that causes 2hp electrical surge to the individual turning on the lights. The backups work fine. Once the backups are switched on, the airlock in area 5 can be repressurized.

2- the storage transhab has six lockers. They contain emergency food, and a few CO2 scrub filters. One is locked. The locked locker contains one of the four sample containers that were brought on board by Randolf Mush. The container has lunar dust with a yellow tinge in it. A mineralogy check DC 20 will identify Uranium Oxide mixed in the lunar dust. Anyone opening the container is exposed to 6hp lung damage.

3- the AG farm has various vegetables growing hydroponically, the foliage heavily overgrown, a window looking out to space. A chemical imbalance has disseminated a hallucinogen in this AG farm that causes 3hp damage to those searching this area. Charisma check is required or the PC sees a missing Astronaut outside the cupola snarling at them without a space suit helmet on, before crawling out of sight on the outside of the Lunar Gateway.

4- the habitat transhab looks disturbed, as though food and scraps were scattered. There is a slow leak here. If spending an hour here the PC undergoes 6hp damage from impact as the hatch from area 1 blows in for injury.

5- this is the airlock to the Ares and spacewalk operations. There is a space suit in a locker. It has a hole which causes 2hp damage as you attempt to pressurize up.

6- Randolf Mush is in the Ares, traumatized by the events on board, the hallucinogen causing them to act violently. Randolf attacks a PC scratching for 1 hp.

Where are the others? Lieutenant Hains was sucked out the airlock due to a cycling error. The other is crawling around on the outside of the ISS without a spacesuit. The Mush mining group found Life in a deep lunar cave and it zombied a crewman who broke the sample container.
