ASTEROID HUNTERS
While the technology to support the work of
professionals is already available, the cost of
conventional kits is far beyond the reach of most.
However, by using 3D printing, along with low-cost
microcontrollers and smartphones, the costs
associated with scaling up the number of
observations can be radically reduced.
The first proof of concept was to see whether an
Ultrascope could be built in South Africa and used to
live-stream a series of images of the Southern Sky to
the USA. The Ultrascope team had the opportunity to
work with the experts at the Office for Astronomical

Development
and South African
Astronomical
Observatory in Cape
Town. The ‘Africa team’ flew
out to Cape Town and spent six weeks
working on developing and testing the Ultrascope,
while conducting community outreach activities on
the ground. The result was a series of incredible
photographs of the night sky, Jupiter, and the
Galilean moons.
Over the course of these six weeks, the team
conducted live-streaming tests to various events in
the US, testing remote access, the web app, global
broadcasting and streaming, and most of all the
capabilities of the scope to identify objects in the
Southern Sky. The team successfully sent images
directly from South Africa over 4G via the cloud to
major public events, including two events held at the
WIRED conference in NYC and one at Re/code in LA.
“If you’re a maker, DIY engineer, citizen scientist or
just a long-time aspiring astronaut with stars in your
eyes, then we’d love to hear from you,” says James.

MARTIAN MAKER MOVEMENT
However, James’s interests aren’t just limited to
planet Earth; he aims to redesign all of the things we
take for granted here on Earth so that they can be
replicated in space. “We want to be able to create
things off-planet; in space jargon, this is called in situ
manufacturing,” he explains. The benefits of enabling
astronauts to manufacture on-site are painfully
obvious; it currently costs around £15 000 to put a
single kilogram of payload into space. “When we get
to Mars, many of the things that we build and
manufacture, from the very large to the very small,
will be done by 3D printing, using Martian resources.
So we were very interested in the challenge of being
able to use 3D printing to create something that could
ultimately be manufactured in situ – either in orbit, or
one day on Mars, without having to be transported
millions of miles,” he says.

GETTING THE PICTURE


A CCD, or charge-coupled device, is a light-sensitive
integrated circuit that captures light and converts
it to digital data. CCDs can produce an image
in extremely low light, which has made them a
transformational technology for astronomers by
providing a far more sensitive light sensor than had
ever previously existed.
