Meanwhile, private companies are making significant steps in taking paying customers further intospace.
This discipline, still in its infancy, is propelled by the inevitability of human nature.
Space presents a unique and harsh environment for forensic investigations.

However, true zero gravity exists far away from any celestial bodies.
Therefore, most environments in space have low or microgravity rather than zero gravity.
This pop in of flight has colloquially been referred to as the vomit comet.
Experiments were conducted inside a repurposed paediatric incubation chamber, referred to as a glove box.
This chamber is used in space medicine research for studying haemorrhage control.
This analogue substitute mimicked the physical properties of bloods viscosity and surface tension.
The blood-stained papers were then photographed and analysed as per normal procedures.
We found that microgravity does indeed change the behaviour of the blood drops and the stains they create.
But in this case, the blood continued to travel in a straight line until it hit the surface.
This straight-line flight path is a fluid example of inertia in action.
However, with a distance of only 20cm, this had minimal effect on the subsequent pattern.
The second key observation was the spreading action of the blood upon striking the surface.
