Two world-renowned scientists have described colonising Mars to escape the climate change problem on Earth as "unrealistic".
British astrophysicist Martin Rees and American astrophysicist Neil deGrasse Tyson spoke on Wednesday during the second day of the World Government Summit, hosted by Dubai.
The duo disagreed with SpaceX founder Elon Musk and late physicist Stephen Hawking’s idea of using Mars as a backup planet.
Mr Musk is working towards sending a million people to Mars by 2050 using his Starship fleets. He hopes to send the first un-crewed cargo flight to the planet within this decade.
Dealing with climate change on Earth is a doddle compared to making Mars habitable
“Mars is a very hostile environment,” Mr Rees said. “What I certainly don’t buy is an idea espoused by Elon Musk and by my late colleague, Stephen Hawking, that we should expect that literally millions of people will go and settle on Mars as a way of escaping Earth problems.
“I think that's a dangerous delusion because dealing with climate change on Earth is a doddle compared to making Mars habitable.”
He said living on Mars is “no better than living at the South Pole, the ocean bed or on top of Everest”.
However, Mr Rees said he did believe that humans could be living on space stations in future.
The mysterious Red Planet
It is believed Mars was once very similar to Earth, but now it has a very thin atmosphere mostly made up of carbon dioxide, and is uninhabitable. Spacesuits and special habitats would be required.
Mr Tyson said terraforming Mars – changing the atmosphere enough to support life – would be needed to call the planet home, but it would be a huge task.
“If you want to do that [terraform Mars] to escape climate change and problems here on Earth, consider that whatever it takes to turn Mars into Earth, that's probably a bigger task than to turn Earth back into Earth.
“Both of us align in disagreement with Elon Musk and with the late Stephen Hawking on that.”
Climate change on Earth is caused by deforestation and fossil fuels releasing harmful gases into the atmosphere. This causes average temperatures to increase, the polar icecaps to melt and sea levels to rise. Another cause for concern is an increase in extreme weather patterns.
In 2017, the UAE also announced plan to build a human settlement on Mars by 2117.
However, space officials later said the main goal of the project was to help guarantee jobs in Stem (science, technology, engineering and mathematics) for the next 100 years.
Mr Rees also addressed space tourism, saying “it would never be safe” and should be called "space adventure" instead.
Several private firms are working on making space tourism flights possible, including SpaceX and Virgin Galactic. Japanese billionaire Yusaku Maezawa has signed on for the world’s first lunar tourism flight and will take eight civilians with him for free.
Plans for a space hotel and a commercial space station had also been announced.
“To go into space, there's never going to be a routine,” Mr Rees said.
“If this is done, I think it should be done by private players – then they're going to do it cheaper than Nasa or the European Space Agency, and they'll be taking the risk.
“If I was an American, I wouldn't support the manned space programme. It’s expensive because they have got to be so safe. They should leave it to people who are prepared for adventure and take risks.”
Mr Tyson, however, said space tourism could become safe one day, in a similar way to how aviation evolved.
“It's not hard for me to imagine the day when space adventure becomes so safe that you bring grandma and the kids, and no one is worried that you'll never come back,” he said.

Libya's Gold
UN Panel of Experts found regime secretly sold a fifth of the country's gold reserves.
The panel’s 2017 report followed a trail to West Africa where large sums of cash and gold were hidden by Abdullah Al Senussi, Qaddafi’s former intelligence chief, in 2011.
Cases filled with cash that was said to amount to $560m in 100 dollar notes, that was kept by a group of Libyans in Ouagadougou, Burkina Faso.
A second stash was said to have been held in Accra, Ghana, inside boxes at the local offices of an international human rights organisation based in France.

Sole survivors
- Cecelia Crocker was on board Northwest Airlines Flight 255 in 1987 when it crashed in Detroit, killing 154 people, including her parents and brother. The plane had hit a light pole on take off
- George Lamson Jr, from Minnesota, was on a Galaxy Airlines flight that crashed in Reno in 1985, killing 68 people. His entire seat was launched out of the plane
- Bahia Bakari, then 12, survived when a Yemenia Airways flight crashed near the Comoros in 2009, killing 152. She was found clinging to wreckage after floating in the ocean for 13 hours.
- Jim Polehinke was the co-pilot and sole survivor of a 2006 Comair flight that crashed in Lexington, Kentucky, killing 49.
Real estate tokenisation project
Dubai launched the pilot phase of its real estate tokenisation project last month.
The initiative focuses on converting real estate assets into digital tokens recorded on blockchain technology and helps in streamlining the process of buying, selling and investing, the Dubai Land Department said.
Dubai’s real estate tokenisation market is projected to reach Dh60 billion ($16.33 billion) by 2033, representing 7 per cent of the emirate’s total property transactions, according to the DLD.
Haircare resolutions 2021
From Beirut and Amman to London and now Dubai, hairstylist George Massoud has seen the same mistakes made by customers all over the world. In the chair or at-home hair care, here are the resolutions he wishes his customers would make for the year ahead.
1. 'I will seek consultation from professionals'
You may know what you want, but are you sure it’s going to suit you? Haircare professionals can tell you what will work best with your skin tone, hair texture and lifestyle.
2. 'I will tell my hairdresser when I’m not happy'
Massoud says it’s better to offer constructive criticism to work on in the future. Your hairdresser will learn, and you may discover how to communicate exactly what you want more effectively the next time.
3. ‘I will treat my hair better out of the chair’
Damage control is a big part of most hairstylists’ work right now, but it can be avoided. Steer clear of over-colouring at home, try and pursue one hair brand at a time and never, ever use a straightener on still drying hair, pleads Massoud.

Ten tax points to be aware of in 2026
1. Domestic VAT refund amendments: request your refund within five years
If a business does not apply for the refund on time, they lose their credit.
2. E-invoicing in the UAE
Businesses should continue preparing for the implementation of e-invoicing in the UAE, with 2026 a preparation and transition period ahead of phased mandatory adoption.
3. More tax audits
Tax authorities are increasingly using data already available across multiple filings to identify audit risks.
4. More beneficial VAT and excise tax penalty regime
Tax disputes are expected to become more frequent and more structured, with clearer administrative objection and appeal processes. The UAE has adopted a new penalty regime for VAT and excise disputes, which now mirrors the penalty regime for corporate tax.
5. Greater emphasis on statutory audit
There is a greater need for the accuracy of financial statements. The International Financial Reporting Standards standards need to be strictly adhered to and, as a result, the quality of the audits will need to increase.
6. Further transfer pricing enforcement
Transfer pricing enforcement, which refers to the practice of establishing prices for internal transactions between related entities, is expected to broaden in scope. The UAE will shortly open the possibility to negotiate advance pricing agreements, or essentially rulings for transfer pricing purposes.
7. Limited time periods for audits
Recent amendments also introduce a default five-year limitation period for tax audits and assessments, subject to specific statutory exceptions. While the standard audit and assessment period is five years, this may be extended to up to 15 years in cases involving fraud or tax evasion.
8. Pillar 2 implementation
Many multinational groups will begin to feel the practical effect of the Domestic Minimum Top-Up Tax (DMTT), the UAE's implementation of the OECD’s global minimum tax under Pillar 2. While the rules apply for financial years starting on or after January 1, 2025, it is 2026 that marks the transition to an operational phase.
9. Reduced compliance obligations for imported goods and services
Businesses that apply the reverse-charge mechanism for VAT purposes in the UAE may benefit from reduced compliance obligations.
10. Substance and CbC reporting focus
Tax authorities are expected to continue strengthening the enforcement of economic substance and Country-by-Country (CbC) reporting frameworks. In the UAE, these regimes are increasingly being used as risk-assessment tools, providing tax authorities with a comprehensive view of multinational groups’ global footprints and enabling them to assess whether profits are aligned with real economic activity.
