Nautilus Deep Space Observatory

Nautilus Deep Space Observatory 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 Nautilus Deep Space Observatory rather than just read about it. In short: Nautilus Deep Space Observatory (NDSO) (also known as Nautilus array, Nautilus mission, Nautilus program, Nautilus telescope array and Project Nautilus) is a proposed deep space fleet of space telescopes designed to search for biosignatures of life in the atmospheres of exoplanets.

Reference excerpt

Nautilus Deep Space Observatory (NDSO) (also known as Nautilus array, Nautilus mission, Nautilus program, Nautilus telescope array and Project Nautilus) is a proposed deep space fleet of space telescopes designed to search for biosignatures of life in the atmospheres of exoplanets. Daniel Apai, lead astronomer of NDSO from the University of Arizona, and associated with the Steward Observatory and the Lunar and Planetary Laboratory, commented "[With this new space telescope technology], we will be able to vastly increase the light-collecting power of telescopes, and among other science, study the atmospheres of 1,000 potentially Earth-like planets for signs of life."

Overview The NDSO mission is based on the development of very lightweight telescope mirrors that enhance the power of space telescopes, while substantially lowering manufacturing and launch costs. The concept is based not on traditional reflective optics but on diffractive optics, employing a single diffractive lens made of a multiorder diffractive engineered (MODE) material. A MODE lens is ten times lighter and 100 times less susceptible to misalignments than conventional lightweight large telescope mirrors. The NDSO mission proposes to launch a fleet of 35 space telescopes, each one a 14 m (550 in) wide spherical telescope, and each featuring an 8.5 m (330 in) diameter lens. Each of these space telescopes would be more powerful than the 6.5 m (260 in) mirror of the James Webb Space Telescope, the 2.4 m (94 in) wide mirror of the Hubble Space Telescope, and the 1.1 m × 0.7 m (43 in × 28 in) mirror of the Ariel space telescope combined. The NDSO telescope array of 35 spacecraft, when used all together, would have the resolving power equivalent to a 50 m (2,000 in) diameter telescope. With such telescopic power, the NDSO would be able to analyze the atmospheres of 1,000 exoplanets up to 1,000 light years away. In January 2019, the NDSO research team, which includes lead astronomer Daniel Apai, as well as Tom Milster, Dae Wook Kim and Ronguang Liang from the University of Arizona College of Optical Sciences, and Jonathan Arenberg from Northrop Grumman Aerospace Systems, received a $1.1 million support grant from the Moore Foundation in order to construct a prototype of a single telescope, and test it on the 1.5 m (61 in) Kuiper Telescope before December 2020.

Spacecraft Each individual Nautilus unit has a single solid MODE lens and would be packed in stackable form for a shared rocket launch, and once deployed, each unit would inflate into a 14 m (46 ft) diameter Mylar balloon with the instrument payload in the center.

Worked examples

Example 1 — a first encounter with Nautilus Deep Space Observatory

Start with the simplest possible case. Write down what Nautilus Deep Space Observatory 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 Nautilus Deep Space Observatory 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 Nautilus Deep Space Observatory 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 Nautilus Deep Space Observatory

In research: Nautilus Deep Space Observatory 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 Nautilus Deep Space Observatory 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: Nautilus Deep Space Observatory is common in secondary-school and first-year university syllabi. It links to neighbouring topics Northrop Grumman spacecraft, Proposed satellites, Space telescopes, so understanding it makes those chapters shorter.
In everyday life: Look for Nautilus Deep Space Observatory 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.
