Launching Open Hardware Satellites – Hackster’s Blog

https://blog.hackster.io/launching-open-hardware-satellites-93813a1fe842

Created almost twenty years ago the CubeSat standard has lowered the barrier to entry to the point where you can put your own satellite into orbit for not much more than the price of a high end car. The 10 cm × 10 cm × 10 cm cubes have become so common that you can buy most of the structural and flight components of your satellite straight off the shelf.

But what if you don’t want to build something with off the shelf parts?

The UPSat cubesat was constructed by the Libre Space Foundation, and aspired to the first completely open source satellite ever launched.

    and we welcomed the chance to push CubeSat technology to its limits. These tiny spacecraft have become the go-to vessel for researchers and startups doing Earth imaging and monitoring. Compared with traditional satellites, they are relatively inexpensive and small, weighing just a few kilograms, and they can be ready to launch in a matter of months, rather than the years it typically takes to prepare a standard spacecraft. Over time, the onboard sensors and processing that CubeSats can carry have been the beneficiaries of Moore’s Law advancements in electronics, growing more powerful and sophisticated, lighter in weight, and energy efficient.

    FossaSat-1, an Open Source Satellite for the Internet of Things

    The very first satellite built entirely with open hardware was only put into orbit in May last year. It was the UPSat cubesat, and was constructed by the Libre Space Foundation, who tried to keep the amount of off the shelf parts to the absolute minimum, with all of the critical subsystems of the satellite being designed from scratch using open software and open hardware

    However, despite significantly lowering the barrier to entry to putting your own satellite into space, even if you build your satellite using the 10 × 10 × 10 cm CubeSat standard you’re probably looking at a cost of several hundred thousand dollars to launch once construction and launcher costs are taken fully into account.

    From the good news department: The Quetzal-1 team’s Arduino-based CubeSat was put in orbit today! They’ve already shared the dashboard that lets you follow along with its journey: https://bit.ly/2W7dNrO

    Nontoxic, Salt-Based Propellant Could Power Rockets
    https://www.aerodefensetech.com/component/content/article/adt/stories/insider/37557?utm_source=TB_Aero_News&utm_medium=email&utm_campaign=20200903&oly_enc_id=2460E0071134A8V

    In smaller spacecraft such as CubeSat satellites, a salt-based monopropellant is showing promise. The propellant, called FAM-110A, is a mixture of two commercially available salts. It can be used in a combined chemical-electric thruster.

    A rocket engine using the propellant could be practical at almost any pressure level; however, it also leaves a significant amount of liquid residue after it burns. This is undesirable because it means that the combustion is incomplete. The formulation requires changes in order to improve efficiency of its combustion.

    It sounds silly, but a company called Sumitomo Forestry, along with Kyoto University, is developing wooden satellites to reduce space junk.

    Japan to create first wooden satellites that completely burn up on re-entry to eliminate space junk
    The satellite would burn up without releasing harmful substances when it comes back to Earth

    Guatemala’s first satellite, Quetzal-1, operated successfully for 211 days in-orbit a few years ago. Now, the team is making its Arduino-compatible CubeSat design open to everyone! https://github.com/Quetzal-1-CubeSat-Team

    Space garbage is gunking up the skies, but a drag sail keeps the satellite’s lifespan brief.
