NASA chief excited about prospects for exploiting water on the moon

  • NASA scientists have confirmed by direct observation the presence of water on the moon’s surface
  • The presence of water offers a potentially valuable resource not only for drinking but for producing more rocket fuel and oxygen to breathe

NASA Administrator Jim Bridenstine has a vision for renewed and “sustainable” human exploration of the moon, and he cites the existence of water on the lunar surface as a key to chances for success.
“We know that there’s hundreds of billions of tons of water ice on the surface of the moon,” Bridenstine said in a Reuters TV interview in Washington on Tuesday, a day after NASA unveiled its analysis of data collected from lunar orbit by a spacecraft from India.
The findings, published on Monday, mark the first time scientists have confirmed by direct observation the presence of water on the moon’s surface — in hundreds of patches of ice deposited in the darkest and coldest reaches of its polar regions.
The discovery holds tantalizing implications for efforts to return humans to the moon for the first time in half a century. The presence of water offers a potentially valuable resource not only for drinking but for producing more rocket fuel and oxygen to breathe.
Bridenstine, a former US Navy fighter pilot and Oklahoma congressman tapped by President Donald Trump in April as NASA chief, spoke about “hundreds of billions of tons” of water ice that he said were now known to be available on the lunar surface.
But much remains to be learned.
NASA lunar scientist Sarah Noble told Reuters separately by phone that it is still unknown how much ice is actually present on the moon and how easy it would be to extract in sufficient quantities to be of practical use.
“We have lots of models that give us different answers. We can’t know how much water there is,” she said, adding that it will ultimately take surface exploration by robotic landers or rovers, in more than one place, to find out.
Most of the newly confirmed frozen water is concentrated in the shadows of craters at both poles, where the temperature never rises higher than minus-250 degrees Fahrenheit.

Making moon exploration sustainable
Although the moon was long believed to be entirely dry or nearly devoid of moisture, scientists have found increasing evidence in recent years that water exists there.
A NASA rocket sent crashing into a permanently shadowed lunar crater near the moon’s south pole in 2009 kicked up a plume of material from beneath the surface that included water.
A study published the following year in the Proceedings of the National Academy of Sciences concluded that water is likely widespread within the moon’s rocky interior, in concentrations ranging from 64 parts per billion to five parts per million.
Bridenstine spoke to Reuters about making the next generation of lunar exploration a “sustainable enterprise,” using rockets and other space vehicles that could be used again and again.
“So we want tugs that go from Earth orbit to lunar orbit to be reusable. We want a space station around the moon to be there for a very long period of time, and we want landers that go back and forth between the space station around the moon and the surface of the moon,” Bridenstine said.
NASA’s previous program of human moon exploration ended with the Apollo 17 mission in 1972.
Trump last December announced a goal of sending American astronauts back to the moon, with the ultimate goal of establishing “a foundation for an eventual mission to Mars.”
The Trump administration’s $19.9 billion budget proposal for NASA for the fiscal year beginning Oct. 1 includes $10.5 billion for human space exploration.
The budget supports development of NASA’s new Space Launch System rocket and the Orion spacecraft designed to carry a crew into space. The administration envisioned a SLS/Orion test flight around the moon without a crew in 2020, followed by a fly-around mission with a crew in 2023.
As part of the budget proposal, NASA also is planning to build the Lunar Orbital Platform-Gateway — a space station in moon orbit — in the 2020s. NASA said the power and propulsion unit, its initial component, is targeted to launch in 2022.
In May, NASA canceled a lunar rover that was under development, a project envisioned as the first mission to conduct mining somewhere other than Earth.

Saudi ‘smart glove’ inventor thrives in the age of innovation

  • Hadeel Ayoub is the founder of BrightSign, a London-based company specializing in assistive technology
  • BrightSign's signature product is a smart glove that can facilitate communication by individuals with speech disability

LONDON: Saudi inventor and tech innovator Hadeel Ayoub is giving people who can’t speak new hope — and a new voice.

The founder of London-based tech company BrightSign is the driving force behind a smart glove that allows individuals who are unable to speak to communicate by translating sign language into text and speech.

After more than four years’ work, Ayoub, a designer, programmer and researcher in human computer interaction, plans to launch the device later this year.

Some of the biggest beneficiaries will be families with children who have speech disabilities and want to be better connected through technology. The BrightSign glove will enable these children to become better signers and communicators, but can also be hooked up with a web app to provide instant translation in most languages.

The architecture of a BrightSign glove is relatively straightforward: Multiple sensors, embedded under an outer glove, track finger positions, hand orientation and dynamic movements. The hardware is contained inside a slender wristband.

Hand gestures are translated into text that appears on a screen embedded in the glove, and speech is made audible via a mini-speaker. The user can select the voice and speech language.


BIO

• Founder and chieftechnology officer, BrightSign

• Experienced lecturer, researcher and entrepreneur with experience in the higher education industry

• Skilled in innovation, creative coding, programming and design research

• Ph.D. in human-computer interaction and gesture recognition from Goldsmiths, University of London


Ayoub has been featured in Forbes magazine, tech programs on the BBC and Discovery channels, and has spoken at discussions organized by Britain’s Financial Times and Guardian newspapers. She has also taken part in a number of exhibitions with innovation and assistive technology as their themes.

Recalling the inspiration for the smart glove, the Saudi inventor said she was originally designing a device for an air-draw program — the air was the canvas, and the hands and fingers were the drawing tools. Her aim was to replace the mouse and keyboard with trackable wearable technology.

On the basis of her design, Ayoub was selected to represent her university at an IBM global hackathon in artificial intelligence for social care. She reprogrammed the glove to translate sign language and won the competition.

When news of the smart glove was circulated in the media, Ayoub’s inbox was flooded with inquiriesttt from parents wanting the glove for their children, from speech therapists for their patients, and from teachers for their students.

The tech innovator quickly realized there was a need for this kind of technology and decided to make it the focus of her Ph.D. research.

“I want to break the current barriers facing those who wish to broaden their experience with sign language beyond the current traditional method,” Ayoub said.

She believes that at least three improvements are urgently needed: Integrating children with disabilities into mainstream classrooms; equipping adults who have disabilities with technologies that will help them perform tasks as well as their peers manage; and making smart-glove devices available in public locations such as airports, shopping malls, government offices and hospitals to offer a smoother service to visitors with disabilities.

A global award winner for her technological innovation, Ayoub regularly tests and improves the BrightSign glove, which she describes as a work in progress.

“The glove has gone through multiple rounds of prototyping and testing. I have implanted the users’ feedback to develop hardware, software and design,” she said.

“It is now being used in six schools to help non-verbal children overcome their communication challenges in the classroom.”

Ayoub said that further studies would help her develop the final product. “I am now taking glove pre-orders on the BrightSign website,” she said.

The Saudi inventor said that she has always been “a progressive thinker and a dreamer of possibilities,” and described a childhood spent immersed in books rather than playing with dolls.

She remembers her family library with fondness and reminisces on quiet evenings spend reading.

As well as being an innovator, Ayoub is a mother who talks lovingly about her children.

“They are very much involved in the development phases of BrightSign,” she said. “I consider their opinions on the products designed for children. I always encourage them to do what they love since that would mean that they will excel in it.

“They get excited every time they see someone using BrightSign and they can see how it helps people live better.

“They also understand the concept of tech for good and aspire to work one day on technologies with a social impact.”

Ayoub sees herself as problem solver with an eye for technical detail, a kind of instinctive trouble-shooter. “When I attempt to solve a problem, I go through cycles of trial and error until I achieve a breakthrough,” she said.

“I encountered a number of problems that were unprecedented, so I wasn’t able to turn to a source or a reference. I guess this is what prompted me to get creative and think outside the box, which eventually put me on the innovation route.

“I find dead ends challenging. When someone tells me that something has never been done, it does not mean that it is not doable. On the contrary, it motivates me to keep going until I find a solution.”

As for the current model of innovation, Ayoub admires the global interconnectedness.

“The mindset now is collaborative rather than competitive,” Ayoub said.

“I am part of inventors’ groups in Saudi Arabia, the Gulf region and the Middle East. Most of us got business training at some point in order to secure investment and go into production.”

I find dead ends challenging. It motivates me to keep going to find a solution.

Hadeel Ayoub

Being a innovator has been far from a walk in the park for Ayoub. She believes what really pushed her in her chosen field was her desire to learn something new in every degree she pursued, starting with design, then programming and, finally, technology.

“More often than not I find myself the only woman speaking at a tech conference or giving a tech talk at an event,” she said. “I am proud to represent my country in global exhibitions and am even prouder when I walk away with awards at competitions.

“I hope that I can inspire young girls to experiment with technology and use it to enhance their respective practices.

“I have created a ‘women in tech’ group where we have regular meetings to share our challenges and extend our support each other.”

Based on her experiences, Ayoub has a message for young Saudis: “This is the age of innovation and entrepreneurship. If what you are passionate about doesn’t exist as a field of knowledge, create it.

“Learn how to code. It will be useful in any career you pursue and will enable you to integrate technology into your practice.”
