Space Technologies at Cal (STAC): We are a student organization at UC Berkeley with the goal of enabling life beyond Earth.
Motivation for Campaign
We are launching multiple projects in the coming year and would love for you to join us on our journey of enabling space research! In order to do this we have set up a space program to test experiments in space at a low cost. We also utilize a high-quality network of university partners and industry advisors to push technologies in the space community forward through high-impact research. STAC provides a platform for these groups and advisors to collaborate and make strides in far reaching technologies that are connected to major problems in the space industry today.
We would love for you to join our journey and help lay the groundwork for our space program!
This campaign is specifically highlighting our High Altitude Balloon and Microgravity Programs, but STAC has many more research projects as explained below.
High Altitude Balloon Program:
The program's goal is to create a standard high altitude balloon (HAB) payload that can fit any experiment inside. This will enable us to crowdfund research project ideas from the community and around the world. Currently we have partnered with NASA Ames, NASA JPL, Berkeley Research Labs, Lawrence Berkeley National Labs, and plan to do more!

Microgravity payloads are vessels containing groups of experiments that are carried to space on rockets. Our payloads will be used to test experiments in outer-space to further aerospace research at Berkeley and around the nation. The microgravity program will eventually consist of annual launches using standardized STAC payload designs that provide a low-mass enclosure and easy integration.
Mini 3D Printed Model
This is is an example of what you can get if you support us. This is a mini 3D printed model of our standardized chassis for our project. We use this standard form factor for our microgravity and CubeSat projects.

Detailed Project Descriptions
HAB High Altitude Balloon (HAB)
What's the simplest way to simulate life on Mars from Earth? Sending life to near-space environments. The Earth's atmosphere above 90,000 ft provides a close replica of Mars's atmosphere, which is easily accessible through our HAB project!
HAB is a program that enables a standardized system to test research experiments in a near-space environment. While there are a variety of space applications for high altitude balloons, the current project will focus on the long term goal of creating a reliable high altitude balloon for future STAC experiments. This way, observations can be made above the Earth’s atmosphere at a low cost.
The first balloon was launched on March 4, 2018. It was equipped with a camera, electronic sensors to test the efficacy of our system, and bio-exposure units for our experiments. The first research experiment originated from a STAC member, and tested the adaptability of micro-organisms capable of surviving harsh environments on Earth to near-space in partnership with NASA. Subsequent balloon launches will contain various experiments sourced from the UC Berkeley academic community, the outside space community, as well as from within STAC. This will form the foundation of a long lasting STAC HAB program with recurring launches for years to come!
How will lifeforms, like humans, react to living in space? Scientists around the world are studying this question to no avail. However, launching a microgravity payload is the best way to test their theories about life in space!
Microgravity payloads are vessels containing groups of experiments that are carried on rockets. Our payloads will be used to test experiments in outer-space to further aerospace research at Berkeley and around the nation. The microgravity program will eventually consist of annual launches using standardized STAC payload designs that provide a low-mass enclosure and easy integration.
The Interstellar Microgravity Experiments (TIME)
Our first payload, the Interstellar Microgravity Experiments (TIME), will detail how being in a low-gravity environment - like space - will affect lifeforms, optics, and physical mechanics. We recently won the Blue Origin Payload Competition at Dent:Space. This achievement allows us to send a mini scientific payload onto Blue Origin's New Shepard Spacecraft through NanoRacks for free.
C. elegans & Roundworms
Our microgravity research regarding laser ablation of asteroids, revival of C. elegans (roundworms), and laser communication, works towards proving the viability of interstellar travel. Laser propulsion systems could theoretically propel nano-satellites carrying live passengers into interstellar space and these experiments provide the first incremental tests to either push this theory forward or disprove it. Our C. elegans project involves suspending C. elegans into an immobile state, and re-animating them once they are in space to see their reaction.
Laser Communication and Ablation The UCSB DeepSpace Laboratory has already written papers on the applications of laser communications in space. Alongside their researchers, we will send some of their laser communication electronics into low-gravity to see if the transmission is affected in any way.
Our goal for the laser ablation experiment is to include a small vacuum with an asteroid-like sample to image the plume exhaust and compare it with what we see in the lab on Earth.
We have been working on the next microgravity payload, after our initial set of microgravity experiments. We will reuse our chassis and electronics systems design from the TIME project to minimize engineering overhead for future STAC payload launches.
We hope to use the second set of microgravity experiments to cement TIME as an annual project within STAC. With the payload enclosure and interface already designed, TIME will be a great platform for us to explore new and scientifically-significant research ideas every year. The microgravity payload program allows future members the ability to research their own specific interests from the vast array of topics that are affected by microgravity, and keep the future of STAC on the path towards pushing the frontier of space research.
TIME-2, the official second set of microgravity experiments within STAC, is currently pursuing an array of biology experiments, with a focus on bacteria, stem cells, and CRISPR technology. All micro-organisms that we hope to launch into microgravity must stay alive for at least the duration of the flight, over ten hours including the pre-launch window. These organisms are difficult to keep alive and must be kept in a carefully controlled (37C and 5% atmospheric CO2) environment. We were motivated by this problem, leading to the current goal of designing a lightweight low-power incubator for TIME 2.
The CubeSat deployer mechanism deploys a smaller swarm of Printable Circuit Board satellites (PCBsats). The PCBsats will orient themselves and communicate with each other using a combination of laser, LED, and RF technologies. The PCBSats and CubeSat deployer have a directly impact the advancement of swarm spacecraft technologies, increasing human connectivity and communications both on Earth and in space!
STAC is also interested in this technology because it is an incremental step towards improving the Technology Readiness Level (TRL) of recent work on directed energy (laser) propulsion of small wafer-scale spacecrafts. This technology has led to a technically-sound conversation on achieving relativistic interstellar spaceflight. All of these concepts come from NASA-funded work through the NASA Innovative Advanced Concept programs DEEP-IN and DEIS, led by Professor Philip Lubin of the UCSB Experimental Cosmology Group.
Our 3U CubeSat will deploy several PCBSats that are held within the CubeSat. This CubeSat will act as a communication link and mothership for all the PCBSats once they are deployed. We will have altitude control, a radio link down to Earth, GPS, and numerous other electronic components within the CubeSat.
Each individual PCBSat will deploy individually and in a controlled manner to enable laser communication testing between the two. Currently, we are using the KickSat Sprite board (see their previous Kickstarter) as our base model for the PCBSat design. In addition, we will add magnetorquers and maximum power point tracking (MPPT) to expand the PCBSat functionality. This will provide a great technological and scientific demonstration of PCBSats for in-space missions.
AI Resource Rover
In collaboration with the NASA Ames Space Portal Office's Lunar Commercial Operation and Transfer Services (LCOTS) concept, we will contribute to the manifestation of a moon resource base by prototyping an autonomous resource rover. The autonomous rover is designed to be capable of detecting, collecting, extracting, and returning lunar resources back to the central lunar base for further refinement. The prototype will consist of a robust mechanical body capable of navigating the terrain, an end effector for sifting through lunar regolith, a resource extraction module, a resource collection module, and a resource storage unit.
The Artificial Intelligence (AI) team focuses on writing and simulating the execution of reinforcement learning algorithms for autonomous control. This task is similar to developing a self-driving car. However, a rover’s driving environment differs greatly from that of a car, presenting challenges that we seek to address. Primarily, the terrains of Earth, Mars, and the Moon are fundamentally different. Self-driving cars are normally tested on paved roads, while a rover operates in a far more unruly landscape. We use imaging data from NASA Ames and JPL, among other resources, to provide information about the landscape to both our rover’s decision-making processes and the terrain simulation software. Most importantly, the driving impetus for the AI team is that the rover cannot accept and use real-time expert navigation efficiently.
Smart Extraterrestrial Environment Design (SEED)
How would you live on Mars once you get there? With the recent hype around colonizing Mars, most people have not considered how humanity would sustain itself once it gets there. A biosphere, sustainable ecosphere, is the solution!
SEED is a manufactured replication of a sustainable, self-contained, terra-like ecosystem that would provide humanity with a means to survive extraterrestrial establishments. The biosphere would provide shelter, production of goods, and power for energy-efficient regenerative systems. Agriculture can be processed for food, biofuels, pharmaceuticals, and other resources. SEED can serve as a direct way to supply astronauts and space colonies while minimizing commercial orbital transport load.
Biospheres will open a new dimension of production in space beyond the mechanical and electrical systems of NASA's current capabilities and will serve as a home which models our own. Therefore, SEED is the gateway to sustained life on planetary bodies. The environment aims to implement 'smart' controls and operation software to maintain the biome's equilibrium and continuous function.
HOW STAC WORKS
Space Technologies at Cal (STAC) is a community of 62 Berkeley student researchers working on high altitude balloons, microgravity experiments, CubeSat deployers, and more. We are not a typical engineering club that focuses on a set competition but rather focus on making strides in innovating space technologies.
We are a student organization that meets three times weekly with two general meetings and one four hour design meeting on Saturdays. Each STAC project has a group of project members with one team lead, Engineering experts help all teams with issues they may face in a particular engineering subfield, and the leadership core consists of a group of execs as well as development officers. The STAC member structure is organized to encourage collaboration, productivity, and collective thinking.

Risks and challenges
We are students that work solely on our own and only operate with the support we receive from our local community, industry contacts, and crowdfunded donors. This means we do everything voluntarily and are self-motivated by our own commitment to drive space research forward.
We have shown a clear path of success with our HAB-1 launch, but still have yet to fly our microgravity experiment. We also work on many projects besides microgravity and HAB projects as a means of doing research.
We don't expect many delays with our HAB program since we set the program timeline (besides minor weather issues). For the Microgravity program, we are flying the payload on ab industry rocket so the launch window for this flight is out of our control.Learn about accountability on Kickstarter
