SABIA-Mar

SABIA-Mar is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand SABIA-Mar rather than just read about it. In short: SABIA-Mar (Spanish: Satélites Argentino-Brasileño para Información Ambiental del Mar, Portuguese: Satélites Argentino-Brasileiros de Informações Ambientais do Mar), originally called SAC-E by CONAE, is a dual satellite joint Earth observation mission. The mission objective is to study the oceanic biosphere, its changes over time, and how it is affected by and reacts to human activity.

Key takeaways

SABIA-Mar belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SABIA-Mar to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SABIA-Mar from memory before moving on to harder problems.

Reference excerpt

SABIA-Mar (Spanish: Satélites Argentino-Brasileño para Información Ambiental del Mar, Portuguese: Satélites Argentino-Brasileiros de Informações Ambientais do Mar), originally called SAC-E by CONAE, is a dual satellite joint Earth observation mission. The mission objective is to study the oceanic biosphere, its changes over time, and how it is affected by and reacts to human activity. It will focus on the monitoring of ocean surfaces, especially studying the ocean ecosystem, the carbon cycle, and marine habitats, as well as ocean mapping. This collaboration between the Argentine (CONAE) and the Brazilian (AEB) space agencies was originally supposed to make two identical spacecraft with Argentina supplying the payload and Brazil the satellite bus. The satellites, SABIA-Mar A and SABIA-Mar B, were supposed to fly in 2017 and 2018, and operate until 2021. By 2016, CONAE announced that a new agreement had been reached, where Argentina would build SABIA-Mar 1, and Brazil would build SABIA-Mar 2. The Argentine satellite, SABIA-Mar 1, is supposed to fly in 2024.

SABIA-Mar 1 SABIA-Mar 1 will be designed and built by the Argentine technological company INVAP. They will act as prime contractor and integrator, as well as supply two instruments. It is expected to be launched in late 2024, have a 5-year design life, and fly on a Sun-synchronous orbit with a four-day revisit frequency. It successfully passed PDR in April 2016 which marked the end of Phase B development, and the project entered Phase C (detailed design). In April 2018, the Critical Design Review (CDR) of the flight segment was approved.

SABIA-Mar 2 SABIA-Mar 2 will be built in Brazil on the Multi-Mission Platform (MMP), the satellite bus developed for Amazônia-1. It will have a service module with a dry mass of 292 kilograms (644 lb) and a power budget of 304 watts, and a payload module with a mass of 219 kilograms (483 lb) and a power budget of 260 watts. It is expected to be launched sometime in the 2020s.

Worked examples

Example 1 — a first encounter with SABIA-Mar

Start with the simplest possible case. Write down what SABIA-Mar claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to SABIA-Mar before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about SABIA-Mar ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of SABIA-Mar

In research: SABIA-Mar appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses SABIA-Mar in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: SABIA-Mar is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2024 in spaceflight, Earth observation satellites of Brazil, Proposed satellites, so understanding it makes those chapters shorter.
In everyday life: Look for SABIA-Mar outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is SABIA-Mar in simple terms?

Why does SABIA-Mar matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study SABIA-Mar?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
