Degree could get you to Mars

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.

Councils spend £78 million on supply staff amid teacher shortage

WELSH GOVERNMENT FACES SCRUTINY OVER AGENCY SPENDING
A RECENT investigation has revealed that 16 out of 22 Welsh councils spent over £78 million on agency staff for supply teachers and teaching assistants during the 2023/24 academic year. The data, obtained through Freedom of Information requests by the Welsh Conservatives, highlights the growing reliance on temporary staff in schools across Wales.
Pembrokeshire County Council spent £1,833,915, according to the data.
The Welsh Conservatives have criticized the Labour-led Welsh Government for not tracking this expenditure and argue that funds would be better invested in recruiting and retaining permanent teaching staff. Shadow Education Secretary Natasha Asghar MS stated, “The staggering costs incurred by councils across Wales on agency staff makes it difficult to see any value for money from the taxpayers’ perspective.”

Challenges in recruitment and retention
An Estyn report from earlier this year underscores the challenges in teacher recruitment and retention, particularly in secondary schools and Welsh-medium education. The report notes a significant decline in the number of applicants for teaching positions, with some schools needing to advertise multiple times to fill vacancies. This shortage has led to situations where staff are teaching outside their areas of expertise, potentially impacting the quality of education.
Government initiatives and responses
In response to these challenges, the Welsh Government has implemented measures to support supply staff and address recruitment issues. A new national framework contract for agency staff was established in September 2023, aiming to enhance professional learning opportunities and employment safeguards for supply teachers .
Additionally, the government has initiated a pilot National Supply Pool in Ynys Môn, allowing supply teachers to be directly employed by local authorities, granting them access to the Teachers’ Pension Scheme. While this model shows promise, its broader implementation across Wales faces logistical challenges .
Union perspectives
Teaching unions have expressed concerns over the high expenditure on agency staff. A representative from a teaching union described the £78 million spent as a “shocking waste of money,” emphasizing the need for sustainable solutions to staffing shortages.
Local authority views
Local councils, responsible for staffing in schools, have defended the use of agency staff as a necessary measure to cover absences and maintain educational continuity. A Cardiff Council spokesperson noted that schools employ agency staff for various reasons, including covering short-term absences and meeting temporary demands during recruitment processes.
Conclusion
The significant expenditure on agency staff highlights the ongoing challenges in teacher recruitment and retention in Wales. While the Welsh Government has taken steps to address these issues, including new frameworks and pilot programs, the effectiveness of these measures remains to be seen. Stakeholders across the education sector continue to call for comprehensive strategies to ensure sustainable staffing and high-quality education for students.

University crisis: ‘Credential factories’ blamed for rising debt and low-value degrees

DAMNING REPORT CALLS FOR RADICAL OVERHAUL OF WELSH HIGHER EDUCATION
A BOMBSHELL new report has branded Wales’ university sector as bloated, inefficient, and no longer fit for purpose—accusing it of churning out debt-ridden graduates with degrees that fail to match the needs of the modern economy.
The report, titled The University Industrial Complex and published by the Prydain Centre on Thursday (Apr 10), claims that the eight universities currently operating across Wales have evolved into “credential conveyor belts,” more concerned with racking up tuition fees than providing meaningful education.
In a searing analysis of the state of higher education, the authors argue that mass participation has eroded academic standards, with many students paying tens of thousands of pounds for degrees that leave them underemployed—or unemployed.

The key figures
According to the report, there are over 135,000 students enrolled in Welsh universities—despite Wales having a population of just 3.1 million. The average student debt upon graduation now exceeds £37,000, and one in three graduates finds themselves in non-graduate jobs five to ten years after leaving university.
“This isn’t education—it’s exploitation,” said lead author Chris Harries. “We’ve created a generation weighed down by debt, false promises, and qualifications that offer little in terms of real-world value.”
The paper argues that universities have become “visa mills” reliant on overseas student fees, while whole departments and even campuses are being shuttered due to financial pressures.
A new vision for Welsh higher education
The Prydain Centre proposes a sweeping set of reforms that would see the current eight universities reduced to just three elite institutions—each with a clear and distinct focus:
- Cardiff: a global leader in academic research, STEM and humanities.
- Swansea: a centre for applied sciences and industrial collaboration.
- Aberystwyth and Bangor: hubs for Welsh culture, environmental science and rural leadership.
Student numbers would be halved to around 65,000, with raised entry requirements and targeted support for disciplines linked to national priorities such as engineering, healthcare and technology.
Instead of encouraging mass enrolment, the report champions a shift toward merit-based admission and the reintroduction of rigorous academic standards.
From degrees to digital
In perhaps its boldest proposal, the report calls for the launch of a “Digital Knowledge Hub”—a free or low-cost online platform offering lectures, short courses and learning forums.
Built in partnership with leading universities and ed-tech firms, the hub would be accessible to anyone with an internet connection, enabling lifelong learning without incurring debt.
“Education must be about knowledge, not credentials,” said Harries. “This is not nostalgia for an elitist past. It’s a practical leap toward a fairer, smarter system.”
The case for consolidation
The Prydain Centre argues that maintaining eight institutions spreads resources too thinly and dilutes academic quality. By consolidating funding, the three remaining institutions could become internationally respected centres of excellence.
The estimated £500–600 million annual higher education budget would be more effectively used, the report claims, by reducing duplication and investing in talent, research, and student support.
It also acknowledges that the transition would require careful planning, with phased closures and support for affected staff and students, including relocation options and course transfers.
Calls for Government action
The report urges the Welsh Government to pilot the Digital Knowledge Hub as a first step toward system-wide reform. Ministers are being asked to consider a roadmap for consolidation and entry reform over the next five years.
“Wales has a choice,” the report concludes. “Maintain the failed status quo—or build a higher education system that commands global respect.”
The Welsh Government has been approached for comment.

Public asked to have say on school transport policy

PEMBROKESHIRE COUNTY COUNCIL has launched a public consultation on its School Transport Policy, inviting residents to share their views as part of a wider review into the future of school transport provision.
The local authority currently provides daily transport to school or college for more than 4,500 eligible learners, at an annual cost of over £8 million.
While no specific changes are being proposed at this stage, the Council says public feedback will help shape future policy. Any changes arising from the review would need to be both deliverable and affordable, taking into account ongoing driver shortages and the wider financial pressures faced by the authority.
Should any amendments be made to the policy, they would come into effect from September 2026.
Residents have until Sunday, May 18, 2025, to complete the survey, which can be accessed online at:
https://www.pembrokeshire.gov.uk/have-your-say/school-transport-policy-consultation
Paper copies are also available by calling the Council’s Contact Centre on 01437 764551 or by emailing: school.transport@pembrokeshire.gov.uk
