The spirit of NewSpace is revolutionizing our vision of access to space. Reading keys will enable you to understand the technological and strategic challenges in games with new rules, fixed by ambitious players. Combine the new technologies and management of space access with the classical paradigm of the existing space context.
It is difficult to give a definition of the New Space, but we can say that there are several aspects that characterize the New Space and access to space in the New Space: innovation, private actors, reducing the price of access to space, space for all, awareness of societal challenges. In this course, you will first acquire basic knowledge to understand how to access space. This will concern mission analysis, launchers, and rocket engines design. This introductory information will help you to understand what characterizes space access in the New Space in relation to three main aspects: 1. Methodologies of design, development, and production of launchers and rockets 2. Innovative technologies 3. Sustainable space with the future development of green launchers, towards a green space

The NewSpace is a wide concept that emerged more than ten years. It is difficult to define, but it is relatively feasible to explore the consequences of NewSpace on orbital transportation. The access to space, that’s the major point. In this field, a real revolution has taken place. It is the result of several factors, which are actually the maturity of what was developed in the "traditional space" (or classical) that still has its full place today. The balances have been modified, and this Mooc presents precisely - for access to space - the main issues, openings, technologies, and perspectives that are offered to us.

The propulsion system is the most important subsystem of any launch vehicle: it provides the thrust and Isp needed to complete the mission. The objective of this week is to provide you with an introduction to the rocket engines used in launch vehicles for space access. You will understand the fundamentals of propulsion systems, and you will understand how to relate the propulsion system to the launch vehicle mission analysis. This will allow you to understand, next week, how disruptive technologies and innovative methodologies in the new space affect the future generation of rocket engines. The week starts with an introduction to how rocket engines work, some orders of magnitude of power, and an introduction to fundamental performance parameters. Then the different types of rocket engines will be presented: liquid, solid, and hybrid. The week will end with a focus on liquid propellant engine technologies: subsystems and cycles.

In this week you will be able to understand what are the main aspects that characterize access to space in the new space. Using the knowledge you gained in week 1 on mission analysis and week 2 on propulsion systems, you will be able to understand how the design, production, and use of launchers and rockets are affected by the New Space. During this week, we will give you an overview of the production methodologies and the main disruptive technologies that characterize New Space rockets and launchers. Finally, we will discuss sustainable space, highlighting both the issues raised by New Space and the actions that could be taken.

It was intriguing to learn about rockets in a way I never thought I would learn. It was super-challenging to learn the intimate details of rocket propulsion math, but satisfying.

Can you add math exercise after each lecture (before taking quizzes) that will hone student's understanding ? Appreciate !
Frequently asked questions
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
