{{Nowrap| Hey! Welcome to the Stanford Satellite Team! Whether you're an incoming frosh, alumni, PhD, or even not a part of the Stanford community, we're glad you're here. Our current mission [[ Sequoia | '''Project Sequoia''']] is a 3U (about the size of a long shoe box) fully in-house imaging satellite that will demonstrate CubeSats as a user-defined service with changeable machine learning models.

=== ''Sapling Giganteum'': 2022–2023 ===

<div style="text-align: center;">[https://calendar.google.com/calendar/u/0/embed?src=5or10qu0uhtfqcdqb3knrpn3r8@group.calendar.google.com&ctz=America/Los_Angeles '''SSI Updated General Event Calendar''']</div>

=== ''Sapling'' ''Sempervirens'': 2020–2023 ===

Also referred to as Sapling-1, this was the first of the ''Sapling'' 1U cubesats (better descriptions to come + photos!)

== Sequoia 2019-Present 🌲 ==

=== Sequoia: 2019–2020 ===

Sequoia is an open-source, 3U CubeSat that will demonstrate on-board image classification and processing with updateable machine learning models. The goal of the project is to obtain a high volume of scientifically important imagery for ecological and climatology research. Researchers many times have no need of images saturated with clouds or uninteresting areas—so why not filter them out with convolutional neural networks? We will retrain Sequoia’s deep learning with images taken by the satellite, uplinking improvements. The Stanford Student Space Initiative is developing deep learning models for forest fire risk assessment and detection and a number of other applications. The mission architecture is user definable with the operator specifying desirable image locations or types and resolutions, and the satellite maximizing delivery of fully open-source images.

Here's our [https://github.com/stanford-ssi/Sequoia in-progress github] (not in any finalized state) for the project. A full public project rundown of all systems, code, and designs will be released before we launch.

Project materials can be found in the [https://github.com/stanford-ssi/Sequoia Sequoia GitHub].

== Past Projects ==

=== POINTR: [year]–[year] ===

The principal work of Stanford Satellite Team has been the development of various [[Optical Communications]] technologies. [[POINTR]], a 1U segment of a 3U cubesat launched in 2018 but never conected with ground control due to improper oribit insertion from the launch provider.  

The Satellites Team developed various [[Optical Communications]] technologies, culminating in the launch of [[POINTR]]. This was a 1U segment of a 3U CubeSat launched in 2018, but it unfortunately never connected with ground control due to improper orbital insertion from the launch provider.  

In addition, members have worked in Stanford faculty labs to build:

In addition to projects taken on by the team as a whole, satellites members have worked in Stanford faculty labs to build:
