This is for the Endeavour Class on BlendedSchools

1. The SOHO Spacecraft: How
Does it Work?
Unit 4 Lesson 3

2. So Far
 So far:
 We have looked at what the Solar and Heliospheric
Observatory is
 Discovered what it does
 Looked up the spacecraft’s mission, vision, goals,
and objectives
 Now:
 We are going to find out how it does what it does

3. What does the spacecraft
need?
 In Unit 2 you had a chance to work on engineering
challenges like discovering what spacecraft need
 Spacecraft need a power supply
 The ability to collect data
 The ability to send data to the Earth and receive
commands from the Earth
 The ability to change orientation
 Protection from radiation and micrometeorites

4. This Lesson
 In this lesson you will discover, report on, and
learn how and why the Solar and Heliospheric
Observatory is one of the most prolific space data
collection systems in space history.
