Kosmos 1887

Kosmos 1887 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 Kosmos 1887 rather than just read about it. In short: Bion 8 or Kosmos 1887 (in Russian: Бион 8, Космос 1887) was a Bion satellite. Mission Bion 8 carried a payload of biological and radiation physics experiments from nine countries.

Key takeaways

Kosmos 1887 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kosmos 1887 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kosmos 1887 from memory before moving on to harder problems.

Reference excerpt

Bion 8 or Kosmos 1887 (in Russian: Бион 8, Космос 1887) was a Bion satellite.

Mission Bion 8 carried a payload of biological and radiation physics experiments from nine countries. The landing was several hundred miles from the expected recovery site, which resulted in considerable difficulties. The biological payload on the spacecraft included 2 monkeys, 10 rats, fruit flies, grasshoppers, beetles, guppies, Hynobiidae, Chlorella ciliate, newts and corn. More than 50 NASA-sponsored scientists were involved in conducting the 33 American experiments on board. One of these experiments, a study of radiation levels in the space environment, did not require the use of any biological subjects. The United States conducted only one experiment on the primates flown on the biosatellite. The remaining American experiments were performed on tissue samples from five of the flight rats. A number of these experiments were extensions of the studies conducted on the Spacelab-3 mission in April 1985. The other countries involved in conducting experiments on the mission were the Soviet Union, Poland, Czechoslovakia, the East Germany, France, Romania, Bulgaria and Hungary. The European Space Agency (ESA) also sponsored some experiments. The United States was responsible for developing flight and ground-based hardware, verifying testing of hardware and experiment procedures, developing rat tissue sampling procedures, and transferring tissues and data from the Soviet Union after the flight. One of the mission's noteworthy features was the rat biospecimen sharing program, which allowed a great number of rat tissue samples to be analysed. The objective of the U.S. experiments was to investigate the effect of microgravity on various body systems. The primate experiment was designed to study the growth and development of the peripheral skeleton. Rat studies encompassed a broad array of disciplines. The effects of microgravity on cardiac, liver, small intestine and bone tissue, liver function, skeletal growth, hormone levels and metabolism were studied using various approaches. Other studies investigated changes in the immune, nervous and reproductive systems, in muscle and connective tissue and in skeletal and mineral homeostasis. Another experiment was conducted to evaluate radiation exposure during the flight and to measure the shielding effectiveness of the spacecraft. Ten 12-week-old male specific pathogen free Wistar rats were flown in the Rodent-BIOS. Two rhesus macaques(Macaca mulatta) named Drema and Yerosha occupied the Primate-BIOS.

Worked examples

Example 1 — a first encounter with Kosmos 1887

Start with the simplest possible case. Write down what Kosmos 1887 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 Kosmos 1887 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 Kosmos 1887 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 Kosmos 1887

In research: Kosmos 1887 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 Kosmos 1887 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: Kosmos 1887 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1987 in spaceflight, 1987 in the Soviet Union, Bion satellites, so understanding it makes those chapters shorter.
In everyday life: Look for Kosmos 1887 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.
