Science and exploration are the WHY and WHAT - let’s talk about the HOW:

an

 engineering perspective

Tina Büchner da Costa, ArianeGroupMSc Aerospace EngineeringMSc Business psychology

Where science meets engineering

SCIENTISTS:a science goal

Example: Explore planet Mercury

SUBJECT

SCIENTISTS:

a rationale

WHY?

Poorly

explored

so

far

Understand

history and formation of all inner planets

SCIENTISTS/

ENGINEERSa scope

WHAT?

Input

for ENGINEERING:Mission requirements

ENGINEERS:Technical requirements

ENGINEERS

:Design process for spacecraft/instruments/launcher/ground segment

HOW?

WHAT

exactly?

The ‚WHAT‘: Bepi Colombo spacecraft

As

long

as

there will be

science

goals

,

there

is

a

need

of brilliant

engineers to

make things happen!
