A '''satellite''' is used by the Black Mesa Science Team in their efforts to halt the alien invasion. It is featured in ''Half-Life'' and its expansion ''Half-Life Decay|Decay''.

The science team at the Lambda Complex needed a satellite in orbit to end the alien intrusion from Xen. As Hazardous Environment Combat Unit|the military had aborted the initial attempt, Gordon Freeman is sent to the Sector_E Altitude Launch Center to launch the satellite delivery rocket himself. The purpose of the satellite was later elaborated upon in the expansion, ''Decay''.

===''Half-Life Decay''===
It is explained that the satellite controls major recovery systems of the facility,''Half-Life Decay'', ''Domestic Violence'' "A satellite controls major recovery systems. Locate a security guard who knows the satellite signal codes." and it must be in orbit for them to operate.''Half-Life Decay'', ''Code Green'' "A satellite must be in orbit for recovery systems to operate. Upload the satellite signal codes before the delivery rocket launches." The science team wants to use the satellite to orchestrate a resonance reversal which would seal the dimensional rift between the worlds. The rocket cannot launch without the all-clear codes, so Gina Cross and Colette Green are sent to the Level 3 Dormitories by Richard Keller|Dr. Keller to find a Black Mesa Security Force|security guard who knows the codes. Afterwards, they travel to the Black Mesa Air Control building so that they can set the air space monitor to send the codes, allowing Gordon to launch the rocket.

===''Half-Life 2 Episode Two''===
The satellite launch sequence is mirrored in ''Episode Two''. Alyx Vance states that Arne Magnusson|Dr. Magnusson wanted to use White Forest satellite|a different satellite to tune into the old array the science team had set up at Black Mesa, but he was unable to due to the Combine. The satellite launched by Gordon in ''Half-Life'' is part of this pre-existing array. Eventually, the Resistance|rebels are successful in launching a satellite to shut down the superportal. The array is not mentioned again for the rest of the game, so it is unknown if it was ultimately used.

==Behind the scenes==
The satellite was to play a larger role in the storyline. There was originally going to be a satellite array which had to be active to tune the Lambda portal. One section of the array was in the Lambda core, one was in Earth's orbit, and one was in Xen as seen in ''Half-Life Blue Shift|Blue Shift''.http// The HL Storyline Thread on (September 26, 2003) Furthermore, the player was meant to align a satellite dish at Black Mesa to tune in with the orbiting satellite in the cut chapter ''Communications Center''. This sequence was recycled for ''Half-Life Uplink|Uplink''.''Half-Life 2 Raising the Bar'' (uncorrected proof), page 158

The holographic globe at the launch center is believed to be a leftover from this incarnation of the story. It displays the status of the satellite portal array which is always shown as being offline. It features two satellites circling around the globe and a static satellite stationed near the north pole. There are two unused variations of the globe in ''Half-Life Source'''s files. "online.vtf" displays the status of the array as being online. "activated.vtf" displays the message "warning - xen portal activated" and was possibly intended to be used in the chapter ''Lambda Core''. A holographic table can be seen in FileManual portal.png|one of the level plans.

A satellite referred to as the "Alpha Satellite" is mentioned in one of the Black Mesa Announcement System|automated announcements before the incident. Some of the locations mentioned in the announcements are visited by the player in the later chapters, so this may be the name of the launched satellite. The satellite was to be mentioned for the second time in an announcement in the chapter ''Lambda Core'' "Satellite target system, engaged."

===''Half-Life Decay''===
Originally, the satellite delivery rocket's all-clear codes were to be found in a mission set in the Cut missions from Half-Life Decay|Central Transit Hub. The satellite is referred to as the "Omega Satellite" here. The science team at the Lambda Labs was to explain that something is holding the rift open by force from the other side and preventing them from stopping the alien invasion. They wished to use the satellite to get clean readings on the rift, but this plain was thwarted as the military shut down the launch. Gordon is sent to launch the rocket himself, but he won't be able to because of the system's emergency shut down. In order to override it, Gina and Colette need to find the all-clear codes kept at the Central Transit Hub and upload the signal to the Black Mesa air traffic systems. When this mission was cut, the additional backstory for the satellite was also excised.

===''Half-Life 2 Episode Two''===
According to unused dialog, the original goal of Magnusson's Xenium Resonator to was to create a barrier around the planet rather than shutting down the superportal. Once in orbital range, it was to activate the old satellite launched by Gordon and turn it into a shield with subdimensional properties. Furthermore, it was to block the Combine's access to Earth even if they did manage to restore their portal network.
