African Tech Company Hoping to Fund Space Missions

Mr Lun and his Cape Town-based firm, Hypernova Space Technologies, are eager to provide these toppling satellites a bit much more autonomy.

The company has actually established a thruster system that could provide even the tiniest types of satellites the capacity to walk around.

The business is hopeful that their innovation might be put on nanosatellites which are tiny satellites weighing under 10kg and also, also put on the tiniest of them all, the 10cm dices referred to as cubesats.

There are an estimated 3,200 nanosatellites drifting around in orbit already, and that number is expected to grow rapidly in the near future: SpaceX alone remains in the procedure of launching a constellation of around 42,000 satellites.

Yet specialists are concerned that this explosion in numbers may result in problems.

Without manoeuvrability – the capacity to transform direction – nanosatellites run the risk of colliding with each other, creating space particles which could cause problems for various other missions.

Flexibility would also make it much easier to recover, or get rid of, satellites once their working life was over.

But as nanosatellites are deliberately designed to be little as well as inexpensive, any type of new thruster modern technology needs to be basic to be commercially viable.

Around a decade earlier, Mr Lun found an intriguing thruster innovation that had previously been investigated by Nasa however never ever totally pursued. He discovered that an electrical response might be made use of to vaporise strong steel fuel, a process which after that developed a jet of fast-moving plasma that can propel a satellite along.

One big advantage to utilizing strong gas by doing this would certainly be that the material would certainly be stable sufficient to contribute to a thruster-system prior to launch – getting rid of the requirement for any final fuelling prior to sending satellites off right into area.

“They do not need to fret about loading it up, they do not have to bother with [the material] being toxic, they don’t need to stress over it during launch, something breaking and leaking,” includes Stephen Tillemans, the head of design at Hypernova.
