=== Founding and Construction ===

ES3 was constructed as part of the HEPL physics lab in the 1960s. At the type HEPL had buildings across modern day e-quad, ES3 and ES2 being the only two remaining.  

ES3 was constructed as part of the HEPL physics lab in the 1960s, and believed to be operational by 1972 [https://web.archive.org/web/20080221175405/www.stanford.edu/group/hepl/HEPL_History_opt.pdf (source)]. At the time, HEPL had buildings across modern day e-quad, as shown in [https://purl.stanford.edu/mx948nt2935 this image]. The only buildings that remain today are ES3 (ES2 appears to be a later addition), and Varian buildings (which have received major renovations).

The accelerators in ES3 are unclear. There was a series of linear accelerators developed starting in the 1940s. It's unclear where these were developed ([https://web.archive.org/web/20150622184228/http://web.stanford.edu/group/hepl/documents/HEPL_History_opt.pdf the first in the basement of main quad]), however they predate ES3 and later were installed at SLAC's, which has [https://www6.slac.stanford.edu/about/our-story/history completed before 1693], before ES3 was finished.

=== Dark Matter Reearch ===

[[File:Mx948nt2935 00 0001-2.jpg|thumb|Tunnel schematic on south side of ES3, including tunnel A expansion]]

In the 1990s, ES3 became the home of dark matter research. In particular, the researchers expanded Tunnel A to be larger and more cavernous, allowing detection of cosmic rays with shielding provided by the Earth. Reports here suggest that the tunnels were 10m before expansion [TODO find schematics of that]

SSI was originally working out of the room in Durand, which suited the club as it originally was a space enthusiast club than a project based engineering club. However as the club began pursuing enineering projects, the space quickly became a limiting factor.

In 2017, SSI moved into ES3. Unsubstantiated lore in the club suggests this was due to an incident where a high schooler hurt their hand while drilling, which eventually caused the university to realize the space was not suited for engineering work. SSI was given the M300 suite [https://hepl.stanford.edu/news/stanfords-student-space-initiative-group-sets-shop-hepl-southend-station-iii#:~:text=An%20energetic%20group%20of%20Stanford,of%20HEPL%20South%2FEnd%20Station%20III <nowiki>[source]</nowiki>].

As the club grew, SSI expanded slowly into the basement. It's suspected this was in 2018 or 2019, and there was never a formal agreement to use the downstairs space but the building manager graciously let us as it was underutilized. This downstairs space was named Dragon, and the upstairs space ISS.

ES3 was chosen as one of 15 buildings on campus to have solar installed on the roof. Installation occurred in 2016, and is now among the largest rooftop solar arrays on campus. [https://news.stanford.edu/stories/2017/04/sun-rooftop-photovoltaic-panels-electricity-stanford (Source)]

SSI's involvement in construction began in 2023. Lawton Skaling, Matthew Nguyen, and Amy Huang met with the construction planners and coordinated SSI's continued presence during the move. Initial plans involved moving SSI either to a basement room under M300 or the M200 suite, the latter of which the construction crews eventually selected. Due to demolition of Flight Club's Cedar Hall at the same time, at one point the Stanford administration also tried to add Flight Club to M200, but pushback from both clubs eventually prompted the administration to give Flight Club a room in Durand instead.

The first phase of the construction involved the refurbishment of M200, where walls were removed and new appliances installed. Partway through this phase, SSI's downstairs lab was briefly relocated to the south side of the basement, while construction began on the north side to demolish the restrooms and closets,and refurbish the north tunnel for the [TODO] lab.

In phase two of construction, SSI moved from the basement into M200, which would be the new second home from the club. M300 was unchanged through it all. SSI was also given a shipping container outside ES3 for long-term storage.
