They were unsure about whether Juno would stay on course and go into orbit around Jupiter.

They believed that Juno would probably undergo some damage in the atmosphere of Jupiter.

They knew that Juno was likely to get closer to Jupiter than any other spacecraft had.

They were excited to start receiving information about Jupiter from Juno.

“But Juno will get much closer than any of these past missions, which weren’t designed to survive the dangerous conditions surrounding Jupiter.” (paragraph 7)

“The biggest obstacle to getting close to Jupiter is the intense radiation around it.” (paragraph 8)

“Before Juno went into orbit, its star tracker was shut off to prevent interference.” (paragraph 10)

“That way Juno can avoid the most-intense patches of charged particles and limit the damage they are expected to cause.” (paragraph 11)

"It’s so big that a thousand Earths could fit inside it."

"Juno will get much closer than any of these past missions, which weren’t designed to survive the dangerous conditions surrounding Jupiter."

"Juno will orbit Jupiter at least 37 times, collecting data to relay back to Earth."

"One instrument, for example, called a microwave radiometer, is measuring how much water is in Jupiter’s atmosphere."

They designed Juno to be large enough to resist Jupiter's gravity.

They programmed Juno to avoid Jupiter’s magnetic poles entirely.

They developed shielding and a specific orbit path to protect Juno from radiation.

They built Juno to land safely on Jupiter's surface after data collection.

"Juno’s onboard instruments are crucial to the mission."

"Juno will get a close-up look at different parts of the planet with each flyby."

"Engineers designed Juno to follow an orbit that dips in and out of Jupiter’s radiation belt."

"Jupiter, Saturn, Neptune, and Uranus are our solar system’s four gas giants."

A curved structure used in architecture

An underground chamber filled with fuel

A lightweight spaceship component

"Engineers put its electronic components inside a vault about the size of an SUV’s trunk."

"Juno’s onboard instruments are crucial to the mission."

"It’s made of the element titanium (Ti), a light but extremely strong metal."

"One instrument, for example, called a microwave radiometer, is measuring how much water is in Jupiter’s atmosphere."

By using chronological order to build suspense and highlight problem-solving efforts

By comparing Jupiter to other planets throughout the text

By organizing the text as a series of questions and answers

By describing Juno’s mission first and then providing historical background on Jupiter

Paragraphs 1–3, which describe Juno’s arrival and mission timeline

Paragraphs 4–5, which explain the physical features of Jupiter

Paragraph 14, which details the formation of the solar system

Paragraphs 12–13, which describe Juno’s instruments
