The first thing many media seem not to understand is the methodology followed by Space X, which is completely different from what the traditional aerospace builders do. While the latter prefer to spend their money on a long project life cycle, including long requirements discussion, and meticulous and detailed test engineering and integration phases, Space X opts for a methodology closer to the experimental scientific method: draw essential requirements, build a prototype, test, fail, learn from failures, build a new improved prototype, and try again. Each reiteration adds quality to the project, up to a point when the prototype is working well, and Falcon 9 (as a sample) becomes the space workhorse with any more competitors in the world. Is that so hard to be understood, for journalists?When a traditional project fails, many billions are wasted, and many years of work are canceled. When a “normal” failure occurs during Space X’s reiterative project development, very less resources are wasted. And, after all, during the expendable rockets’ age, all the rockets were always wasted, at every launch! The difference is incomparable. Another advantage of this method is its high flexibility. If a project lasts 10 years, it is difficult to take advantage of the technological advances: switching to new technology in a project initiated many years ago forces heavy requirements reviews and unavoidable delays. In a fail-and-repeat project, new technologies and new ideas can be adopted more easily and more quickly, as demonstrated by the thousands of changes and improvements applied to the different starships, super-heavy boosters, and raptor engine prototypes throughout history. Despite the misfortune bearers and the envious, the methodology works. The success of Space X in the launchers market doesn’t lie.

Starship 28 and the Super-Heavy Booster 10 made most of the expected work, and even more than what was expected: while the suborbital altitude was planned, the Starship spacecraft reached 230 km, a low Earth orbit altitude at more than 26,200 km/h. several tests were conducted after the engine cutoff, including a propellant transfer demo and payload dispenser test.

Only two operations have failed. The booster couldn’t make it to descend vertically on its engines, since only 3 of them reignited, and splashed in the Mexican Gulf at little more than 1,000 km/h. The Starship failed during the re-entry in the atmosphere, in the Indian Ocean. We could observe many insulating tiles flying away from the Starship’s body during the first part of the re-entry. At an altitude of 65 km, telemetry from Ship 28 was lost, and the vehicle was destroyed before splashing in the sea.

In the XXI century, the world of orbital launchers has started a revolution, a fundamental change of paradigm: the replacement of expendable rockets with reusable ones is well underway. This presentation summarizes the situation at the beginning of year 2024.

A short bio.
Alberto Cavallo is an Electrical Engineer, graduated at the Politecnico di Torino in 1985. He began his activity with designing electric systems in Fiat Engineering, the engineering and construction company of the FIAT Group, moving soon to control and automation systems in the same company. He was involved in all business areas of the company, which included revamping and new projects of car factories for the FIAT Group as well as large infrastructures, power and cogeneration plants for external clients. Among the projects of that time were the new FIAT factories in Melfi and Pratola Serra, the high speed railways Torino-Milano and Bologna-Firenze, the district heating system of Torino Sud, combined cycle power plants for several hundred megawatts in Italy and in Brazil. Since Fiat Engineering was transferred from the FIAT Group to a new EPC group and then merged with a large EPC company in Milan, he has been involved in large oil and gas and petrochemical projects all over the world. Besides his professional activity, he has always taken part in several cultural activities. He was a member of the Associations of Alumni of the Liceo Classico Vittorio Alfieri of Turin, active in promoting humanistic culture as well as its connection to the technical and scientific area. He manages his own website www.eurinome.it (in Italian only) about philosophy, science and politics/geopolitics. Due to this he got in contact with Adriano Autino and his TDF, then becoming one of the founding members of Space Renaissance International. Besides several papers in his professional area he has written several articles for his own site, for TDF and SRI, coauthoring the book “Three Theses for the Space Renaissance” with Adriano Autino and Patrick Q. Collins. He is currently member of the Board of SRI.

Alfred Anzaldúa talks about inevitability of human expansion into space and the proposal to add an 18th SDG, focused on space development, to the U.N. 2030 Agenda for sustainable development.

The SRI President Bernard Foing and the SRI CEO and Founder A. V. Autino are in agreement on the text of this newsletter, but not on the title(!). We decided therefore to issue it with two titles. The first one, by A.V. Autino, establishes an ideological distance from the governance model that brought the civilization to the current situation, refusing any direct co-responsibility. The title proposed by B. Foing implies that “we” (the global society) are responsible for the general failure since we voted for the current leaders. He also suggested that should “we” (space humanists) be governing, he’s not sure that we would be able to do better than current leaders, for peace and development. Better than warmongers for sure! Replied Autino. However, both titles are true and have their reasons. That’s why we don’t want to choose one…

As soon as the U.N. 2030 Agenda ^[1] was published, some relevant criticalities appeared. The general criteria supporting the concept of sustainability developed by the agenda is an unquestioned limitation to the boundary of Earth’s atmosphere. The 2030 Agenda for Sustainable Development, adopted by all United Nations Member States in 2015, was conceptualized during the traditional aerospace age: outer space was not considered, as a dimension that helps to increase the sustainability of development. Space science and technologies are supporting social and environmental goals on Earth, for many years. Yet that will not be enough, to warrant a really sustainable development. To allow a real sustainable development, it is indispensable and urgent to start civilian space development, outside Earth boundaries. Therefore the UN 2030 Agenda of the Sustainable Development Goals needs to be updated.

Historically, colonialism was initially predicated on a simple “rob and take home” concept. During the first colonialist age, the superpowers of that era (primarily England and France) used to send their agents overseas to obtain precious goods at very low prices, and to bring those goods back to their home countries, selling them at very high prices (today, such practices are far from being obsolete!). Such policies were often socially detrimental, especially when they boosted the use of drugs (e.g., stimulating opium dependence in several Chinese provinces). In many cases, colonialist policies lead to conflicts and wars (in order to ensure control over certain regions). In most cases, nothing positive remained for the colonized populations, since the colonialist behaviors primarily engaged populations with a culture based on robbery and exploitation – not to advance civil rights. Regarding the “new world” (America’s two continents), colonialists have also invaded these territories, stealing the land and natural resources from native inhabitants, and exterminating these inhabitants by any means. During the last age of colonialism (up to the 20th Century), the practice of depredation continued, in many cases retarding or preventing the development of colonized countries, notwithstanding the abundance of natural riches, from which native peoples could never benefit.

Ok, I am listening now to your classical objections. I, for one, have noted this several times while discussing space colonization: in the solar system there are no native intelligent beings, therefore we would not steal anything from anyone, by colonizing territories on the Moon, Mars, Jupiter Moons and beyond. Of course, I am talking about the very essential part of colonialism: to take resources and bring them home. In our cases, to take asteroid and exo-planetary resources from the Moon, asteroids, Mars and beyond, and bring them on Earth surface – why would this be harmful?

Space colonialism would be both a dangerous and harmful undertaking for several reasons.
