To track Mars' reflexes, or the way it wobbles when it is pulled by the sun, an investigation called RISE will
precisely measure the Doppler shift and ranging of radio communications sent between the InSight lander and Earth.
By tracking wobble, scientists can determine the distribution of the Red Planet's internal structures and better understand how the planet is built.
RISE uses the lander's X-band radio link for Doppler tracking of the lander's location with an accuracy of a handful of cm. Since the lander is attached to the planet, this allows the measurement of the rotation of Mars, and particularly variations in its rotation axis.
These rotational variations are related primarily to the size and state of the core, through its effect on the moment of inertia and damping of Mars.

Science and Engineering Practices---
(HS-PS2-1) Analyze data using tools, technology or models (computational, mathematical) in order to make valid and reliable scientific claims....
(HS-ESS1-1) Develop a model based on evidence to illustrate the relationships between systems or components of a system... (HS-ESS1-2) Construct an explanation based on valid and reliable evidence obtained from a variety of sources including students
own investigations, theories, simulations and peer review. (MS-ESS1-3)
Analyze and interpret data to determine scale properties of objects in the solar system. [Clarification Statement: Emphasis is on the analysis
of data from Earth-based instruments, space-based telescopes, and spacecraft to determine similarities and differences among solar system objects.
Examples of scale properties include the sizes of an object’s layers (such as crust and atmosphere), surface features (such as volcanoes),
and orbital radius. Examples of data include statistical information, drawings and photographs, and models.]

Expressions and Equations---
(8.EE.c.7) Analyze and solve linear equations and pairs of simultaneous linear equations..... (HS.Modeling) Graphing utilities, spreadsheets,
computer algebra systems, and dynamic geometry software are powerful tools that can be used to model purely mathematical phenomena
as well as physical phenomena...(NGSS.MP.2) Reason abstractly and quantitatively....(NGSS.MP.4) Model with mathematics....(NGSS.HSN.Q.A.1)
Use units as a way to understand problems and to guide the solution of multi-step
problems; choose and interpret units consistently in formulas; choose and
interpret the scale and the origin in graphs and data displays.
ELA/Literacy:
---(RTS.11-12.1) Cite specific textual evidence to support analysis of science and technical
texts, attending to important distinctions the author makes and to any gaps
or inconsistencies in the account. (RTS.11-12.2) Determine the central ideas
or conclusions of a text; summarize complex concepts, processes, or information
presented in a text by paraphrasing them in simpler but still accurate terms. |
