Sara Russell

Sara Russell 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 Sara Russell rather than just read about it. In short: Sara Samantha Russell (born 1966) is a professor of planetary sciences and leader of the Planetary Materials Group at the Natural History Museum, London. She is a Fellow of the Meteoritical Society and of the Royal Astronomical Society.

Key takeaways

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

Reference excerpt

Sara Samantha Russell (born 1966) is a professor of planetary sciences and leader of the Planetary Materials Group at the Natural History Museum, London. She is a Fellow of the Meteoritical Society and of the Royal Astronomical Society.

Early life and education Russell was captivated by the Moon landing as a child. She studied at the University of Cambridge, where she was introduced to microanalysis by Jim Long. She had started studying natural sciences, but heard that geologists host the best parties, so switched courses. She was inspired to complete a PhD degree in geology after attending a lecture by Colin Pillinger, and moved to the Open University. She won the Royal Astronomical Society Keith Runcorn Prize for the best British doctoral thesis in geophysics in 1993.

Career Russell completed postdoctoral research at the California Institute of Technology and Smithsonian Institution. She joined the Natural History Museum in 1998, where she studied protostars and planets. In 2000 she edited the collection Protostars and Planets IV. Russell is leader of the micrometeorite and meteorite collection at the Natural History Museum, London. She has been on three expeditions to Antarctica searching for meteorites. She has been awarded the Antarctica Service Medal. She was awarded a Leverhulme Trust grant in 2005. In 2006 she studied the meteorites in the early solar system and the protoplanetary disc. On behalf of the Natural History Museum, Russell was part of the team which arranged the acquisition of the Ivuna meteorite in 2008. In 2009 she published the book Meteorite with Caroline Smith and Gretchen Benedix. She won the Geological Society of London Bigsby Medal in 2010. In 2011 Russell took part in an exhibition at the Royal Observatory, Greenwich. She is a science team member of OSIRIS-REx. She was the initial point of contact in the process by which the Tissint meteorite came to be acquired by the Natural History Museum in 2012. In 2014 she studied Moon rocks brought back by the Apollo Astronauts, finding that the lunar crust did not form from a common source. Russell has studied the origin of water in the inner Solar System with Monica Grady. She published Chondrules in 2018, a book which considers the silicate grains that form in the protoplanetary disk. The eponymous asteroid 5497 Sararussell was named after her. Russell is an advocate for diversity in science.

Worked examples

Example 1 — a first encounter with Sara Russell

Start with the simplest possible case. Write down what Sara Russell 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 Sara Russell 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 Sara Russell 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 Sara Russell

In research: Sara Russell 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 Sara Russell 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: Sara Russell is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1966 births, Alumni of the Open University, Alumni of the University of Cambridge, so understanding it makes those chapters shorter.
In everyday life: Look for Sara Russell 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.
