Speaker 1: one tiny satellite at a time. The development of cube
Speaker 1: SATs represents a significant shift in the landscape of space exploration,
Speaker 1: allowing more accessible and cost effective missions be Small satellites,
Speaker 1: measuring as little as ten centimeters per side and weighing
Speaker 1: around a kilogram, were initially conceptualized as educational tools, but
Speaker 1: have since evolved into a cessential components of both governmental
Speaker 1: and commercial space programs. Their rise in popularity stems from
Speaker 1: their compact size, which makes them relatively inexpensive to design,
Speaker 1: build and launch. As a result, CubeSats have opened new
Speaker 1: opportunities for universities, private companies, and even developing nations to
Speaker 1: participate in space missions that would have been prohibitively expensive
Speaker 1: just a few decades ago. The increasing reliance on these
Speaker 1: tiny spacecraft has fostered a dynamic and innovative ecosystem of engineers, scientists,
Speaker 1: and entrepreneurs who are pushing the boundaries of what can
Speaker 1: be achieved in orbit and beyond. In the late nineteen nineties,
Speaker 1: cube SATs were developed by professors Jeordi Puigswarri from California
Speaker 1: Polytechnic State University and Bob Twigs from Stanford University. They
Speaker 1: sought to provide their students with practical experience in designing
Speaker 1: and launching satellites. The simplicity and standardization of cube SAC
Speaker 1: components allowed students to build functioning spacecraft at a fraction
Speaker 1: of the cost and time it took to develop traditional satellites.
Speaker 1: The primary innovation behind cube SATs was their modular design.
Speaker 1: A single unit or one ucube sat measures ten by
Speaker 1: ten by ten centimeters, with additional units such as two
Speaker 1: U or three ucube SATs stacked to increase capacity. This
Speaker 1: standardized sizing enabled the development of cube SAT compatible hardware
Speaker 1: and launch systems, leading to a burgeoning industry that rapidly
Speaker 1: adopted the technology. The first cube sat was launched in
Speaker 1: two thousand three, and since then thousands have been sent
Speaker 1: into space with uses ranging from Earth observation to scientific
Speaker 1: experiments and communications. Early on, CubeSats faced skepticism from the
Speaker 1: aerospace community, which was accustomed to large, expensive satellites with
Speaker 1: well proven capabilities. The notion that something as small and
Speaker 1: cheap as a cube sat could perform meaningful scientific work
Speaker 1: was met with bouts. However, the increasing miniaturization of electronics
Speaker 1: and improvements in materials quickly led to advancements that made
Speaker 1: cube SATs capable of sophisticated tasks. Today, cube SATs are
Speaker 1: used in various applications, including monitoring climate change, testing new technologies,
Speaker 1: and even exploring other planets. Their impact on the space
Speaker 1: industry has been profound, allowing a diverse array of participants
Speaker 1: to engage in space activities that were once the exclusive
Speaker 1: domain of large space agencies and defense contractors. One of
Speaker 1: the key advantages of cube SATs is their ability to
Speaker 1: be launched as secondary payloads on larger missions. Traditional satellites
Speaker 1: are expensive to launch because they require dedicated rockets, but
Speaker 1: cube SATs can hitch a ride with larger satellites, significantly
Speaker 1: reducing launch costs. As space agencies and private companies began
Speaker 1: to recognize the value of cube SATs, Dedicated deployment mechanisms
Speaker 1: were developed, such as the Polypico Satellite Orbital Deployer PEAPOD,
Speaker 1: which allows multiple cube SATs to be released from a
Speaker 1: single rocket. This innovation drastically reduced the cost of accessing space,
Speaker 1: democratizing space exploration in the process. Universities, startups, and even
Speaker 1: high school teams could now design and launch their own satellites,
Speaker 1: contributing to a wave of innovation in the field. CubeSats
Speaker 1: have proven especially valuable in Earth observation, where they can
Speaker 1: be deployed in constellations to provide near real time monitoring
Speaker 1: of the planet. This capability has been particularly useful for
Speaker 1: tracking environmental changes such as deforestation, urbanization, and the movement
Speaker 1: of glaciers. Private companies have seized on this opportunity, with
Speaker 1: firms like Planet Labs using CubeSat constellations to capture daily
Speaker 1: images of the entire Earth. These images are used in
Speaker 1: applications ranging from agriculture to disaster response, offering an unprecedented
Speaker 1: level of detail and timeliness. The small size of CubeSats
Speaker 1: allows for large numbers of them to be deployed at once,
Speaker 1: creating a network of satellites that can cover vast areas
Speaker 1: with frequent updates. This is a stark contrast to the
Speaker 1: traditional approach of using a few large, expensive satellites to
Speaker 1: gather data, which may only provide sporadic coverage. The adaptability
Speaker 1: of cube SATs also extends to scientific research, where they
Speaker 1: are used for experiments in a variety of disciplines. NASA,
Speaker 1: for example, as used cube SATs to test new propulsion systems,
Speaker 1: to study the behavior of fluids in microgravity, and investigate
Speaker 1: space weather phenomenon like solar radiation. One of the more
Speaker 1: ambitious uses of cube SATs came during NASA's Insight mission
Speaker 1: to Mars. Alongside the main Lander, NASA sent two cube
Speaker 1: SATs named Marca and MARCOB, collectively known as the Mars
Speaker 1: Cube one mission. These CubeSats relayed communications from Insight as
Speaker 1: it descended to the Martian surface, demonstrating that small spacecraft
Speaker 1: could play a supporting role in interplanetary missions. The success
Speaker 1: of Marco paved the way for future deep space missions
Speaker 1: involving cube SATs, proving that they could operate far beyond
Speaker 1: Earth's orbit. Despite their advantages, cube SATs are not without challenges.
Speaker 1: Their small size limits the amount of power they can generate,
Speaker 1: the instruments they can carry, and the volume available for
Speaker 1: propulsion systems. As a result, cube SATs are often limited
Speaker 1: to low Earth orbit lo where they can complete their
Speaker 1: missions without the need for complex propulsion. However, innovations in
Speaker 1: miniaturized propulsion systems are beginning to extend the capabilities of
Speaker 1: cube SATs, enabling them to reach higher orbits or even
Speaker 1: venture into deep space. Another challenge is the relatively short
Speaker 1: life span of cube SATs, which typically ranges from a
Speaker 1: few months to a few years. This is due to
Speaker 1: their limited power supply, exposure to radiation in the harsh
Speaker 1: conditions of space. However, advancements and materials in design are
Speaker 1: helping to extend the operational life of cube SATs, making
Speaker 1: them even more attractive for long term missions. The rise
Speaker 1: of CubeSats has also raised concerns about space debris. Given
Speaker 1: the large number of CubeSats being launched, there's growing worry
Speaker 1: about the potential for collisions and the creation of debris
Speaker 1: that could pose a hazard to other spacecraft. Space agencies
Speaker 1: and companies are working on solutions to mitigate this risk,
Speaker 1: such as designing CubeSats that can urbit themselves at the
Speaker 1: end of their missions, or creating systems to track and
Speaker 1: avoid potential collisions. Additionally, regulatory frameworks are being developed to
Speaker 1: ensure that cube sat operators follow best practices for reducing
Speaker 1: the risk of space debris. The commercial potential of cube
Speaker 1: SATs is vast, and private companies are increasingly investing in
Speaker 1: their development and deployment. Start Ups specializing in CubeSat technologies
Speaker 1: have attracted significant funding from venture capitalists, while established aerospace
Speaker 1: firms have incorporated CubeSats into their business models. For instance,
