Degree could get you to Mars

Published

on

AN OPPORTUNITY to work on the 2020 European Space Agency (ESA) / Roscosmos mission to Mars has taken an Aberystwyth University student a step closer to a career in the space industry.

Ariel Ladegaard from Bergen in Norway has just returned from the Atacama Desert in Chile where he has been taking part in an ESA field trial of a test rover, as scientists prepare to go in search of life on the red planet.

As an undergraduate student on the Space Science and Robotics degree programme at Aberystwyth, Ariel was invited by computer science lecturer Dr Helen Miles to look at how images sent back from Mars could be corrected to reflect the planet’s true colours.

Dr Miles and fellow space scientist Dr Matt Gunn at Aberystwyth University have been working on PanCam, the mission’s panoramic camera system.

Tasked with capturing stereo and 3D images of the Martian terrain, work on PanCam is led by the Mullard Space Science Laboratory at University College London.

At Aberystwyth, Dr Gunn and his team have developed a hardware emulator for PanCam and a unique colour swatch inspired by the stained glass windows of medieval churches to ensure it accurately captures colours on the sun-blanched planet.

Images taken during the mission will be studied by geologists as they look for minerals that might indicate the presence of water and the building blocks of life.

For his final year undergraduate project in 2018, Ariel was set the challenge of developing a prototype software package that could compensate for imperfections in the mission’s camera, and the wear and tear of working in Mars’ hostile environment.

“Driving around on Mars is challenging and time-consuming, so you want to be certain that you’re going in the right direction. Images taken from a distance will be analysed to look for possible sites where the rover can use its ground penetrating radar and drill, so they need to be as accurate as possible.

“Once back on Earth the images will be processed by a radiometric correction pipeline which automatically adjusts them based on our knowledge of how the images were taken and how the camera responds to light in various conditions.”

Ariel’s undergraduate project focused on developing a proof of concept framework for the correction pipeline and drew on work done on the ground software for NASA’s James Webb Space Telescope.

Now a PhD student at Aberystwyth, Ariel is working on the next phase and developing the algorithms that go into correcting the images.

Ariel said: “Aberystwyth has been great. It is everything I could have hoped for from an education in terms of how quickly I have been able to get involved in something meaningful to me, a real project. My goal is to work in robotic space exploration, a niche industry that can be difficult to enter but Aberystwyth has certainly opened the door for me.”

Speaking of his work on ExoMars, Ariel added: “It has been very nice to see just how open people in the ExoMars community have been to new actors coming in with questions and their own ideas and views on things. At first, I was a bit overwhelmed by the mission itself as it has been going on for a long time. There’s quite a barrier to entry for new people in understanding just how everything fits together, not just on a technical level, but also on the social and political levels. The more I have delved into that, however, the more I’m confident I have something to offer to the project.”

As well as developing image processing software, Ariel has been involved with ExoFiT, ESA’s Airbus-led field trials using an ExoMars-like prototype rover in Spain and Chile.

Working near the Paranal Observatory high up in the Atacama Desert in February 2019, he was part of the team testing the mission’s procedures and approaches to gathering science.

It was also an opportunity to put the image processing pipeline to the test, with pictures sent back to the UK for correction.

Ariel added: “Aberystwyth’s involvement with ExoMars revolves around calibration of the mission’s camera system and correction of images – understanding how the cameras work and how we can process and interpret the images. It was good to be able to put some of the work we have been doing in Aber to the test in Chile and gather valuable test data.”

Before taking up his studies at Aberystwyth, Ariel was a student at the Norwegian Centre for Space-related Education near Andenes in northern Norway.

He worked for seven years in the television and film industry before returning to higher education as a mature student on the BSc Space Science and Robotics degree at Aberystwyth University’s Department of Computer Science.

Engineering learner Reuben heading for ‘pole position’

Published

on

ENGINEERING learner Reuben Whitehead has been turning heads with his mechanical talents when he recently designed and built his very own battery powered go-kart.

Reuben, who is a passionate Formula One fan, works part-time at West Wales Karting and decided to rebuild the kart earlier this year after they kindly donated a pre-existing kart to him.

The process involved stripping the kart down to a bare chassis and then refurbishing it. This was followed by implementing the electrical aspect of the kart and fabricating mounts for both the batteries and motor made from carbon fibre and steel.

The key components and materials used were steel for the chassis, aluminium for the rims, and an inclusion of carbon fibre for both the motor mounts and battery.

The motor produces 2.5hp and has an efficiency rate of 90% when in operation. The torque produced is 8.4-foot pounds when in operation and the motor revs 1500RPM.

Reuben explained the purpose of his project, “I built the Go-Kart because I am passionate about motorsport and enjoy karting both in local competitions and with friends so for me the opportunity to build an electric kart was exciting and something that would require me to use my skills that I have developed throughout my time at the College. I also built the project as I knew it was something that I would enjoy undertaking and be able to learn new skills along the way. Being able to get hands on with a kart and understand both the fundamentals and intricate aspects was important for my development as an aspiring motorsport engineer, hopefully one day with Formula One.”

Reuben took his first test drive in the car earlier this month using the track based up at West Wales Karting.

Reuben also discussed what inspires him to achieve his dream career.

Reuben explained, “The individuals who inspire me are my mum, for how brave and courageous she is, for always believing in me and supporting me. My late stepdad, he never gave up even at the toughest of times and always kept fighting even when the odds were against him as well as teaching me that if you work hard enough anything is achievable. Finally, Lewis Hamilton for showing that again with hard work you can achieve anything and that no dream/goal is too big, also the way in which he conducts himself after tough losses on the racetrack.”

An articulate learner, Reuben spends a large amount of time in the machine workshop whilst studying at the College where he has developed skills in working with lathes and milling machines, hand fitting tool techniques as well as CAD and precision measurement practices which has aided his knowledge into the world of car design and engineering.  

Aside from Reuben’s College studies, he has self-taught himself many transferable skills.

Reuben said, “I can’t take all the credit, having been fortunate enough to have experience of refurbishing classic cars with my stepdad growing up, as well as being able to build rally cars when on work experience whilst studying in my first year of College, this has certainly helped me learn and build a skillset that can be applied in numerous engineering environments. Spending time in the workshop and learning from tutors who have real industry experience has helped me.”

Curriculum Area Manager for Engineering Will Bateman, expressed how proud the department is of Reuben, “Reuben has worked at a consistently excellent standard throughout the two-year programme. We are incredibly proud of his final project, that has showcased his skills and learning from the course. Reuben is a true engineering ambassador having spoken to numerous 14–16-year-old groups on choices post-compulsory education.”

Reuben plans on becoming a Motorsport Engineer in Formula One after his studies and this project has fuelled his motivation to show potential employers just how talented he is.
