A new planetary simulation chamber at New York University Abu Dhabi could transform how scientists in the UAE conduct space research, allowing them to recreate extreme planetary environments.
Researchers will be able to replicate the surface conditions of the Moon, Mars, asteroids and the Martian atmosphere by adjusting the gas composition, pressure and temperature inside the controlled chamber.
Dr Dimitra Atri, an astrophysicist at NYUAD and manager of the project, told The National in an exclusive interview that research from the chamber will complement data being gathered by UAE spacecraft on other planets and asteroids.
“Initially it was called the Mars Simulation Chamber because our focus was Mars, but then we got involved in the Emirates lunar programme and the asteroid belt mission,” he said. “So now we have a very flexible system in the chamber where we can explore different parts of the solar system, starting from our neighbour, the Moon, all the way to asteroids.”
The lab is also equipped to create simulated regolith – loose rock and dust that covers the surface of planets – allowing scientists to better understand the science behind these environments.
“We can mix them with different types of minerals and chemicals, which are found in space conditions, and we can understand the physics and chemistry of what is going on,” he said. “When space probes send back data, we’ll be able to analyse the underlying mechanisms behind the different observations they capture.”
How the chamber can help future missions
The chamber also has an optical system capable of recreating solar conditions across different regions of the solar system. Researchers will be able to expose samples to intense ultraviolet radiation, mimicking the effects of prolonged space exposure.
Dr Atri is part of the scientific team behind several UAE-led missions, including the Hope probe that is orbiting Mars, the Moon exploration programme and the space flight to an asteroid belt between Mars and Jupiter.
The parts of most of these craft are usually sent abroad for environmental testing to ensure they can survive the harsh conditions of space travel. Dr Atri said the chamber can be used for testing.
“To test whether an instrument can go into space, it must be space certified, it needs to be put in those extremely low and high temperatures, extremely low pressures of space,” he said. “And generally, people ship it to the US, mostly to JPL [Nasa’s Jet Propulsion Laboratory] to test these things, but now we’ll be able to do it in our lab itself.”
This could be the first such technology in the UAE that replicates the environment of a number of celestial bodies. Although Zayed University operates a small Mars simulation chamber and Khalifa University has a compact thermal vacuum chamber, which aims to ensure satellites can survive the harsh environment of space, NYUAD’s chamber also has vacuum capabilities for testing components, including for spacecraft that are bound for other celestial bodies.
“We have a load-lock chamber. It works exactly like an airlock so we can maintain vacuum conditions for several months at a time,” said Dr Atri. “This load-lock chamber can be depressurised or pressurised. We can change its atmospheric composition and temperature, allowing us to transport samples continuously in and out of the space environment.”
On a global scale, planetary simulation chambers are used by some of the world’s leading space agencies and institutions. JPL's Dustie, for example, simulates the temperature and air pressure of other planets. It was used to replicate the carbon dioxide ice found on Mars' southern hemisphere, supporting the study of Martian geological formations known as araneiform terrain.
“We can also train students and scientists here,” said Dr Atri. “One of the main goals of the UAE government is local capability development, and the chamber is an example of a technological and scientific capability.”

Multitasking pays off for money goals
Tackling money goals one at a time cost financial literacy expert Barbara O'Neill at least $1 million.
That's how much Ms O'Neill, a distinguished professor at Rutgers University in the US, figures she lost by starting saving for retirement only after she had created an emergency fund, bought a car with cash and purchased a home.
"I tell students that eventually, 30 years later, I hit the million-dollar mark, but I could've had $2 million," Ms O'Neill says.
Too often, financial experts say, people want to attack their money goals one at a time: "As soon as I pay off my credit card debt, then I'll start saving for a home," or, "As soon as I pay off my student loan debt, then I'll start saving for retirement"."
People do not realise how costly the words "as soon as" can be. Paying off debt is a worthy goal, but it should not come at the expense of other goals, particularly saving for retirement. The sooner money is contributed, the longer it can benefit from compounded returns. Compounded returns are when your investment gains earn their own gains, which can dramatically increase your balances over time.
"By putting off saving for the future, you are really inhibiting yourself from benefiting from that wonderful magic," says Kimberly Zimmerman Rand , an accredited financial counsellor and principal at Dragonfly Financial Solutions in Boston. "If you can start saving today ... you are going to have a lot more five years from now than if you decide to pay off debt for three years and start saving in year four."

Quick pearls of wisdom
Focus on gratitude: And do so deeply, he says. “Think of one to three things a day that you’re grateful for. It needs to be specific, too, don’t just say ‘air.’ Really think about it. If you’re grateful for, say, what your parents have done for you, that will motivate you to do more for the world.”
Know how to fight: Shetty married his wife, Radhi, three years ago (he met her in a meditation class before he went off and became a monk). He says they’ve had to learn to respect each other’s “fighting styles” – he’s a talk it-out-immediately person, while she needs space to think. “When you’re having an argument, remember, it’s not you against each other. It’s both of you against the problem. When you win, they lose. If you’re on a team you have to win together.”
