Mohammed VI (satellites)

Mohammed VI (satellites) is a astronomy 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 Mohammed VI (satellites) rather than just read about it. In short: The Mohammed VI satellites are a series of two Moroccan Earth observation and reconnaissance satellites, namely Mohammed VI-A and Mohammed VI-B, developed and built by Airbus Defence and Space and Thales Alenia Space based upon the Astrosat-1000 satellite bus. They are Morocco's first optical imaging satellites, and are operated by Morocco's Ministry of Defense, with an expected service life of 5 years.

Key takeaways

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

Reference excerpt

The Mohammed VI satellites are a series of two Moroccan Earth observation and reconnaissance satellites, namely Mohammed VI-A and Mohammed VI-B, developed and built by Airbus Defence and Space and Thales Alenia Space based upon the Astrosat-1000 satellite bus. They are Morocco's first optical imaging satellites, and are operated by Morocco's Ministry of Defense, with an expected service life of 5 years. They are named after Mohammed VI, the King of Morocco.

Design

Satellite bus Both satellites are based on the Astrosat-1000 satellite bus. They have a launch mass of 1,110 kg (2,450 lb) and have three deployable solar arrays, and an expected service life of around 5 years.

Propulsion The satellites have four hydrazine thrusters for reboosting its orbit and keeping its altitude.

Launch

Mohammed VI-A

The Mohammed VI-A satellite, Morocco's first spy satellite, was launched on Vega flight VV11 on board the Vega launcher from Guiana Space Centre ELA-1, French Guiana, on November 8, 2017. It was launched to low Earth Sun-synchronous orbit with an inclination of 97.9°.

Mohammed VI-B

The Mohammed VI-B satellite, Morocco's second spy satellite, was launched a year later on Vega flight VV14 from Guiana Space Centre ELA-1, French Guiana, on November 28, 2018. It was launched to Low Earth Sun-synchronous orbit with an inclination of 97.9°.

Worked examples

Example 1 — a first encounter with Mohammed VI (satellites)

Start with the simplest possible case. Write down what Mohammed VI (satellites) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Mohammed VI (satellites) 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 Mohammed VI (satellites) 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 Mohammed VI (satellites)

In research: Mohammed VI (satellites) appears in astronomy 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 Mohammed VI (satellites) 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: Mohammed VI (satellites) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2017 in spaceflight, 2018 in spaceflight, Earth observation satellites, so understanding it makes those chapters shorter.
In everyday life: Look for Mohammed VI (satellites) 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.
