Nasa plans to test a nuclear thermal rocket within the next five years — which could one day take humans to Mars and beyond.
Currently, it takes at least eight months to reach the Red Planet, but the technology would help reduce that time significantly.
Nasa is teaming up with the Defence Advanced Research Projects Agency, part of the US Department of Defence, to develop the nuclear thermal rocket engine and test it in space.
“Nasa will work with our long-term partner, Darpa, to develop and demonstrate advanced nuclear thermal propulsion technology as soon as 2027,” said Nasa administrator Bill Nelson on Tuesday.
“With the help of this new technology, astronauts could journey to and from deep space faster than ever — a major capability to prepare for crewed missions to Mars.”
The project, known as the Demonstration Rocket for Agile Cislunar Operations nuclear thermal rocket programme, uses a fission reactor to generate extremely high temperatures.
A nuclear engine then transfers that heat to a liquid propellant, which is expanded and expelled through a nozzle to propel the spacecraft.
Stefanie Tompkins, director of Darpa, said the agency has historic ties with Nasa — having worked on the Saturn V rocket with the space agency. This took humans to the Moon for the first time, in 1969.
“The space domain is critical to modern commerce, scientific discovery, and national security,” she said.
“The ability to accomplish leap-ahead advances in space technology through the Demonstration Rocket for Agile Cislunar Operations nuclear thermal rocket programme will be essential for more efficiently and quickly transporting material to the Moon and eventually, people to Mars.”
Under the agreement, Nasa will lead the technical development of the engine, which will be integrated with Darpa’s experimental spacecraft.
The last nuclear thermal rocket engine tests conducted by the US took place more than 50 years ago, under Nasa’s Nuclear Engine for Rocket Vehicle Application and Rover projects.
Elon Musk’s SpaceX is also building a Mars rocket, called Starship.
Starship will use six Raptor rocket engines that are powered by liquid methane and liquid oxygen. These will not significantly reduce the present journey time.
Nasa is also working with the Department of Energy to develop other space nuclear technologies, including the space agency's Fission Surface Power project.
This involves developing nuclear power plan concepts that could be used on the surface of the Moon and Mars, which would help supply energy to human settlements.

How tumultuous protests grew
- A fuel tax protest by French drivers appealed to wider anti-government sentiment
- Unlike previous French demonstrations there was no trade union or organised movement involved
- Demonstrators responded to online petitions and flooded squares to block traffic
- At its height there were almost 300,000 on the streets in support
- Named after the high visibility jackets that drivers must keep in cars
- Clashes soon turned violent as thousands fought with police at cordons
- An estimated two dozen people lost eyes and many others were admitted to hospital
Top tips to avoid cyber fraud
Microsoft’s ‘hacker-in-chief’ David Weston, creator of the tech company’s Windows Red Team, advises simple steps to help people avoid falling victim to cyber fraud:
1. Always get the latest operating system on your smartphone or desktop, as it will have the latest innovations. An outdated OS can erode away all investments made in securing your device or system.
2. After installing the latest OS version, keep it patched; this means repairing system vulnerabilities which are discovered after the infrastructure components are released in the market. The vast majority of attacks are based on out of date components – there are missing patches.
3. Multi-factor authentication is required. Move away from passwords as fast as possible, particularly for anything financial. Cybercriminals are targeting money through compromising the users’ identity – his username and password. So, get on the next level of security using fingertips or facial recognition.
4. Move your personal as well as professional data to the cloud, which has advanced threat detection mechanisms and analytics to spot any attempt. Even if you are hit by some ransomware, the chances of restoring the stolen data are higher because everything is backed up.
5. Make the right hardware selection and always refresh it. We are in a time where a number of security improvement processes are reliant on new processors and chip sets that come with embedded security features. Buy a new personal computer with a trusted computing module that has fingerprint or biometric cameras as additional measures of protection.

Tips for job-seekers
- Do not submit your application through the Easy Apply button on LinkedIn. Employers receive between 600 and 800 replies for each job advert on the platform. If you are the right fit for a job, connect to a relevant person in the company on LinkedIn and send them a direct message.
- Make sure you are an exact fit for the job advertised. If you are an HR manager with five years’ experience in retail and the job requires a similar candidate with five years’ experience in consumer, you should apply. But if you have no experience in HR, do not apply for the job.

Conflict, drought, famine
Estimates of the number of deaths caused by the famine range from 400,000 to 1 million, according to a document prepared for the UK House of Lords in 2024.
It has been claimed that the policies of the Ethiopian government, which took control after deposing Emperor Haile Selassie in a military-led revolution in 1974, contributed to the scale of the famine.
Dr Miriam Bradley, senior lecturer in humanitarian studies at the University of Manchester, has argued that, by the early 1980s, “several government policies combined to cause, rather than prevent, a famine which lasted from 1983 to 1985. Mengistu’s government imposed Stalinist-model agricultural policies involving forced collectivisation and villagisation [relocation of communities into planned villages].
The West became aware of the catastrophe through a series of BBC News reports by journalist Michael Buerk in October 1984 describing a “biblical famine” and containing graphic images of thousands of people, including children, facing starvation.
Band Aid
Bob Geldof, singer with the Irish rock group The Boomtown Rats, formed Band Aid in response to the horrific images shown in the news broadcasts.
With Midge Ure of the band Ultravox, he wrote the hit charity single Do They Know it’s Christmas in December 1984, featuring a string of high-profile musicians.
Following the single’s success, the idea to stage a rock concert evolved.
Live Aid was a series of simultaneous concerts that took place at Wembley Stadium in London, John F Kennedy Stadium in Philadelphia, the US, and at various other venues across the world.
The combined event was broadcast to an estimated worldwide audience of 1.5 billion.
