Meteor-1 1

Meteor-1 1 is a earth 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 Meteor-1 1 rather than just read about it. In short: Meteor-1-1 was the Soviet Union's first fully operational weather satellite, and was launched 26 March 1969 on a Vostok rocket. It weighed between 1,200 and 1,400 kilograms, and was originally placed in orbit at an altitude of 650 km.

Key takeaways

Meteor-1 1 belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Meteor-1 1 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Meteor-1 1 from memory before moving on to harder problems.

Reference excerpt

Meteor-1-1 was the Soviet Union's first fully operational weather satellite, and was launched 26 March 1969 on a Vostok rocket. It weighed between 1,200 and 1,400 kilograms, and was originally placed in orbit at an altitude of 650 km. Two solar panels were automatically oriented toward the Sun. It ceased operations in July 1970. Meteor-1-1 was the first of a series of 25 launches of similar spacecraft (model designation Meteor M 11F614) from 1969 to 1977. The satellite provided near-global observations of the Earth's weather systems, cloud cover, ice and snow fields, and reflected and emitted radiation from the dayside and nightside of the Earth-atmosphere system for operational use by the Soviet meteorological service. Some of the processed data and TV pictures from the satellite were distributed to meteorological centers on the world. Meteor-1-1 deorbited and fell in Antarctica on 26 March 2012, on the anniversary of its launch 43 years earlier, according to the Russian Defense Ministry. "According to data provided by the Main Center for Space Reconnaissance, which is part of Russia's Space Forces, fragments of the Meteor-1-1 satellite entered the Earth's atmosphere at 02:17 a.m. Moscow time on Tuesday (22:17 GMT Monday 26 March 2012)," according to Space Forces spokesman Col. Alexey Zolotukhin. He also said that the defunct satellite fell in the Queen Maud Land region of Antarctica, about 690 kilometres (430 miles) from Argentinean research station of Belgrano II.

Worked examples

Example 1 — a first encounter with Meteor-1 1

Start with the simplest possible case. Write down what Meteor-1 1 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Meteor-1 1 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 Meteor-1 1 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 Meteor-1 1

In research: Meteor-1 1 appears in earth 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 Meteor-1 1 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: Meteor-1 1 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1969 in the Soviet Union, Spacecraft launched in 1969, Weather satellites of Russia, so understanding it makes those chapters shorter.
In everyday life: Look for Meteor-1 1 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.
