Make sure they don't get in the way of a departing rocket... there's already so much junk that the likelihood of civilian space travel collision is already high to make it an insurance nightmare that will stop it in its tracks... necessitating even more money on path clearance and guidance tech...of course assuming civilians and life on earth hasn't been destroyed by the reduced ozone layer destroyed by the aluminum and other materials of concern being dissolved in the upper atmosphere.... although, optimistically, by having enough microsatellites reflecting sunlight the planet can be technically cooled to beat global warming - just be mindful of reaching global freezing conditions...

Space exploration has long been the domain of massive, multi-million dollar satellites, requiring complex launch vehicles and specialized expertise. However, the advent of nanosatellites and CubeSats has revolutionized the field, democratizing access to space and enabling a new era of scientific discovery and technological innovation. Nanosatellites are a broad category of satellites that weigh less than 10 kilograms (22 pounds). They come in various shapes and sizes, but the most common type is the CubeSat. CubeSats adhere to a standardized design, with each unit measuring 10 centimeters (3.9 inches) on a side. These units can be combined to create larger satellites, with the most common configurations being 1U (one unit), 3U, and 6U.

Nanosatellites and CubeSats are tackling their big challenges with even bigger innovations. Think deployable solar panels that catch sun rays like a sunflower and batteries that last longer than your favorite series. The Asteroid Prospector Flyer, a CubeSat, is navigating space debris with the ease of a seasoned astronaut, thanks to advanced autonomous systems. These breakthroughs are not just tech marvels; they're shaking up space law to make space more welcoming for these mini explorers. With these strides, the tiny titans of space are opening new frontiers for innovation and making the cosmos accessible to all.

Low cost is a key issue. By keeping them relatively inexpensive by eliminating redundant systems and large fuel stores, we reduce their lifespan on orbit, but can launch and replace them more frequently. The low cost allows us to do that and still keep overall mission costs lower.
