	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).

	~~=== Mark Accelerators ===~~		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~~ ===		=== Gravity Probe B ===
	[[File:~~Mx948nt2935 00 0001~~-2.~~jpg~~\|thumb\|Tunnel schematic on south side of ES3, including tunnel A expansion]]		Gravity Probe B was a satellite designed in collaboration between Stanford, NASA, and Lockheed Martin to test theories of General Relativity [https://en.wikipedia.org/wiki/Gravity_Probe_B (source)]. It was first proposed in the 60s and didn't launch until 2004, and is believed to be housed in ES3 through development in the 1980s as a facility with vibration and temperature control sufficient for calibrating the spacecraft. A marker in ES3 marked the location of the accelerometer calibration, precisely determining the gravity at a point in ES3.
	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 engineering 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>].
