Swarms of Cheap Spacecraft for Solar System Exploration

TL;DR

Engineers at the University of California Berkeley are developing a mission called Bliss, which aims to launch low-cost spacecraft with solar sails to explore thousands of targets within the solar system, including asteroids and comets.

Transcript

whenever I talk to Engineers about their ideas for sending spacecraft to Alpha centuri with lasers I always like ask about I mean this how can we use this technology here in the solar system it's like perfect to explore tons of other worlds and finally I got somebody who is actually planning just that uh his name is Alexander alvara he's working wi...

Key Insights

• 😘 The Bliss Mission aims to explore multiple targets within the solar system using low-cost spacecraft with solar sails.
• 🇨🇷 The off-the-shelf components used in the spacecraft make them affordable, with each one costing approximately $1,000.
• ☄️ By deploying thousands of these spacecraft, the mission aims to study and retrieve samples from asteroids and comets simultaneously.
• 🥘 The spacecraft's solar sails allow for precise maneuveHhe rs and propulsion without the need for propellant.
• 😒 The ability to miniaturize spacecraft and use solar sails offers potential for future exploration and infrastructure development within the solar system.
• 👻 The deployment of redundant spacecraft ensures a higher chance of success and allows for colocalization.
• 🫠 Solar sails could potentially be used for missions closer to the Sun, but materials with higher melting points would be required.

Questions & Answers

Q: How big are the solar sails used in the Bliss Mission?

The solar sails are about 2 meters across and made of thin, reflective materials. They are attached to the spacecraft using carbon fibers and are approximately 10 grams in weight.

Q: Are the materials used to make the solar sails readily available?

Yes, advancements in the smartphone industry have led to the development of small and lightweight components that are suitable for the solar sails. Additionally, carbon fiber manufacturing techniques and thin film aluminization have improved, making it easier to create the sails.

Q: How would the spacecraft be deployed to their targets?

The spacecraft would be launched into geosynchronous orbit, and each one would be deployed to a specific target, such as an asteroid or a comet. It is possible to deploy multiple spacecraft to the same target, but redundancy and colocalization would be considered.

Q: How would the information gathered by the spacecraft be communicated back to Earth?

One method is to have the spacecraft intercept the International Space Station or a similar object in space, where they can beam down the information. Another method being explored is to beam the information back using laser communication systems.
