TNO Space and Aurora

• Roel Hoekstra, TNO Space
• SRON/NIVR Aurora information meeting
• April 18, 2002

introduction

• TNO Netherlands Organisation for Applied
  Scientific Research
• independent contract research organisation,
  working for government and industry, nationally
  as well as internationally
• well established position in a number of space
  areas such as launcher technology, radar,
  instruments for science and earth observation,
  attitude sensors,
• co-ordination of space activities within TNO
• TNO Space

based research

• Research groups
• - Aerospace Medicine
• - Equilibrium Orientation

10
Artificial Gravity in long-duration space
traveling

• In particular the human factor issues like
• cardiovascular, motion sickness and performance
  consequences of intermittent exposure to
  changing G-levels
• research tool is Desdemona

11
Advantages for ESA and the Netherlands

• Desdemona is ideal artificial gravity lay-out
• Microgravity vs hypergravity ground based
  research
• TNO Human Factors center of excellence for
  selection,
• training and examination of astronauts on
  G-aspects
• Unique facility (close enough to EAC and ESTEC)
• PR, having a unique up-front research facility
• Et cetera
