Scotland’s 1st Spacecraft Is Tiny Satellite with Big Mission

by

GOLDEN, Colo. — Scotland’s first satellite will soon find a home in orbit around the Earth — a forerunner of things to come under a collaborative, national nanosatellite program in the United Kingdom.

Dubbed UKube-1, the small, novel cubesat spacecraft has been constructed by Clyde Space at its West of Scotland Science Park in Glasgow and is completing final testing for launch later this year onboard a Russian Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan. Cubesats measure 10 centimeters a side and generally weigh about 1 kilogram.

The small but powerful spacecraft comprises payloads that include the first GPS device aimed at measuring space weather in Earth’s plasmasphere — the innermost layer of the planet’s magnetosphere. The satellite also comes equipped with a camera that will take pictures of Earth from space and test the effect of radiation on space hardware using a new generation of imaging sensor, and an experiment to demonstrate the feasibility of using cosmic radiation to improve the security of communications satellites and to flight test lower-cost electronic systems.

The UKube-1 satellite also totes a payload made up of five experiments that U.K. students and the public can interact with.

“It’s one small satellite for Clyde and a giant leap for their extraterrestrial export business and a new hope for space science in Scotland,” First Minister of Scotland Alex Salmond said.

UKube-1 is a U.K. Space Agency mission. The mission has been funded jointly by Clyde Space and a number of funding partners including the U.K. Space Agency, the Science and Technology Facilities Council, the Technology Strategy Board and Scottish Enterprise.

 UKube-1 will be supported by three U.K. ground stations.

“We started designing our nanosatellite platform in 2008 as a means to stimulate some funding from the U.K. government as part of a national cubesat program,” Craig Clark, chief executive of Clyde Space, said.

Nanosatellites are the fastest-growing space subsector, with the United Kingdom able to tap into both heritage and expertise that primes the pump in building future small satellites, Clark added.

Clark said there are a number of new developments from Clyde Space on the mission including deployable solar panels — there are three on UKube-1 — as well as advanced attitude and control technology, a sophisticated miniature sun sensor and specialized software that other cubesats can use.

Starting small

There is value in “starting small” as there are many factors that go into working on a nanosatellite, Clark said.

“I think that the main thing to consider in terms of the differences in building a tiny satellite over a much larger satellite is that both have to work in space and perform very similar functions,” Clark said. “Therefore, there is still a massive technical and programmatic challenge in seeing a successful space mission through from start to finish no matter what the size.”

Clark said that many larger space organizations still view nanosatellites as toys. “But the fact of the matter is that they are staying away from them because they can’t see a business case for themselves in producing cubesats,” he said. “Let’s face it, a space company with a turn-over of over $1 billion isn’t going to be interested in a full mission sale of less than $500,000. … It would be too much risk for them.”

This is good news for small space companies, Clark said, as they are able to innovate more and are rapidly increasing the utility value of cubesats. So much so that major space users are now looking to cubesats and nanosatellites to fill gaps in capturing wanted and valuable data, he said.

“The big difference in cost and technical skill when it comes to cubesats over larger missions is the availability of off-the-shelf subsystems that can be used,” Clark said.

Clyde Space has invested its own money into UKube-1 as part of their product development strategy, Clark said.

“Our reason for doing this is because we wanted to develop an advanced cubesat platform that we can then market as a full mission capability for organizations that want to put payloads into space but don’t want to have to worry about the satellite itself,” Clark said.

It is a growing competitive market, with agencies, military and commercial customers hungry to have an active role in space.

“Anyone who puts a satellite into space wants to give the mission the best chance of success,” Clark added. “If we are successful in our business plan, UKube-1 will be the first of many more Scottish satellites.”
