A(n) ______ is any human-made object placed in orbit around a body in space, either with or without crew

Artificial Satellite

Rockets are launched from Kennedy Space Center to the east. Which claim identifies an advantage this has over launching from a space center where rockets would have to be launched to the west?

Earth rotates east, so rockets are sped up by the acceleration of Earth.

The ______ refers to all of the frequencies or wavelengths of electromagnetic radiation

Electromagnetic Spectrum

_______ provide information about weather, temperature, land use, and changes on Earth over time

Images

about the weather

Images of Earth provide information about weather, temperature, land use, and changes over time. The figure below shows an image of Earth. What information does this figure provide?

optical telescope

Imagine that you were in charge of placing a detector aboard a satellite that will travel into deep space. Your first step is to analyze the electromagnetic spectrum, which is shown below. Which type of detector would you place aboard the satellite to study wavelengths coming from space that measure 10^-4 cm?

Which claim describes how the space program has affected Brevard County, Florida?

It transformed it from a rural area to a high-tech center.

______ is the United States agency that explores space through crewed and uncrewed missions

NASA

A mobile, uncrewed vehicle that is used to explore the surface of another planet is called a(n) ________

Rover

Many communication services, such as Internet service and television channels, are provided through the use of satellites. Which reasoning explains why satellites are useful for communication?

Satellite signals can reach a wider area than ground-based signals can.

Melbourne

Scientists come from all over the world to live and work in Brevard County. These people have a direct impact on Florida's economy, particularly their local economies. The map shows the concentration of aerospace employment in Florida. Where do most of the people in Florida who work in aerospace live?

In 2007, University of Florida scientists discovered that microwaves could be used to sterilize sponges. Sponges used in kitchens and bathrooms carry bacteria that can cause disease. The researchers found that exposing the sponges in a microwave oven for 2 minutes killed these bacteria. What can you claim based on this evidence?

Some type of electromagnetic radiation can be useful.

The continuous range of a single feature, such as, wavelength

Spectrum

Firefighters use air tanks when they go into burning buildings. NASA has created new air tanks that weigh 13 pounds less than typical air tanks. These tanks also have a warning device that tells the firefighters when they are running out of air. What is the name used for this type of product?

Spinoff

Which of these claims describes one way that technology assists humans with observing distant galaxies?

Telescopes that orbit Earth collect data about the composition of distant stars.

Most of the money is spent on research.

The Florida Space Grant Consortium is a group of Florida universities and colleges that work together to support space research and education. NASA provides funding for the Florida Space Grant Consortium. The graph below shows how NASA funds were allocated in 2007. Based on evidence from the graph, what can you claim about how NASA funds are used to support the Florida Space Grant Consortium?

All the staff members working in the x-ray department at Broward Community Hospital in Florida wear radiation badges. Why do these staff members wear the badges?

The badges indicate the amount of radiation the staff members have been exposed to.

one fifth (1/5)

The circle graph below shows the different industries involved in aerospace in Florida. Based on the graph, about what fraction of Floridians employed in the aerospace industry in 2007 worked in guided missiles and space vehicles?

The signal moves in a straight line, and the curve of Earth would prevent the signal from reaching the receiver.

The diagram below shows how a satellite can be used to relay information. Based on this evidence, why does the sender require the satellite to relay the signal to the destination?

Some planetary images and satellite photographs are made using visible light. Other images are made with radiation from the non-visible portions of the electromagnetic spectrum. Why do scientists study images made with parts of the electromagnetic spectrum other than visible light?

The images reveal information that visible light does not show

Refracting telescopes use lenses. Reflecting telescopes use mirrors. However, both types of telescopes have something in common. Which claim tells how both types of telescopes are similar?

They both concentrate electromagnetic radiation

Which of these studies is most likely performed by remote observation?

a study of a planet that orbits a star other than the sun

Spinoffs from the aerospace industry have contributed to Florida's economy and the economy of the United States. What is a spinoff?

a technology developed for the space program that is now used in everyday life

What types of industries in Florida have experienced the greatest relative growth due to the operations of Kennedy Space Center?
