ARCA is a non profit organization and our main objective is the exploration and colonization of space.

In order to reach these objectives, ARCA builds and launches the most cost effective space vehicles. We are using technologies already existent, in an innovative way, that allow acces to space on a large scale by reducing financial constraints.

We want to accomplish this because we strongly believe that the future of mankind is linked to the exploration and colonization of space.

In the condition in which mankind faces a alarming growth of population, a consumer inflation and a drastic decrease of the planet's resources, finding and exploiting new resources is vital.

Space exploration and colonization will not solve these problems on the short term, but on the long term it is the only option available to mankind.

Although the technology existed and cost reduction was possible, this did not happen because space activities, until not long ago, were exclusive to governmental agencies that did not consider financial efficiency a priority at that time. Now more and more private initiatives are born worldwide. Because of limited budgets, they view space exploration and colonization possible first of all by reducing costs.

In 10 years of activity, we have gained an experience unique in the world, using the lowest budgets compared to our aerospace ahievements. We also have the capability to mobilize hundreds of people from various civilian and military institutions and to coordinate them in order to achieve the objectives proposed by ARCA.

In order to facilitate access to outer space, we have created a family of orbital rockets and a suborbital plane, using cheap, safe and accessible technologies.

The key element in reaching our objectives is the Executor engine

series, first having a thrust to weight ratio of 110, being the third in the world for this criteria. It is also the cheapest first stage engine ever created.

Another element that contributes to the reduced cost of the rockets are the composite materials fuel tanks, that have an empty mass of only 1,2% of the launch mass. Also in this case performance comes at a reduced cost.

Besides the low cost of the developed technologies, ARCA also launches its on vehicles, that contributes to the overall reduced cost.

ARCA wants to become a model of aerospace industry cost reduction, being the only way to open mankind's road to the outer space. We believe it is vital now to make this steps.
