Israeli scientists invent solar powered space travel
Ben-Gurion University researchers create system of tiny solar cells thinner than two sheets of paper which could fill the 'urgent need' for more cost-effective power generation
Israeli scientists have designed a system of tiny solar cells thinner than two sheets of paper for commercial space launches.
Professor Jeffrey Gordon and his team at Ben-Gurion University in the Negev (BGU) worked with US colleagues to develop the solar-power prototype which is now set to be tested at the International Space Station next year.
The BGU team said if successful it would meet “an urgent need” for more cost-effective solar power generation on space flights and be a “major step forward for private commercial space missions,” for which cost is a huge factor.
They said the first-generation prototype – now in production at US naval research labs – was 1.7mm thick, but the second generation is only 0.17 mm thick. One sheet of paper has a thickness of 0.1mm.
The prototype, which was part-funded by an Israeli government grant, will now be subject to rigorous testing in space, to determine the system’s integrity and robustness when dealing with temperature extremes. If it passes then the tiny US-Israeli system could power future missions to Jupiter and Saturn.

Engaging
Being a community platform means so much more than producing a newspaper and website. One of our proudest roles is media partnering with our invaluable charities to amplify the outstanding work they do to help us all.
Celebrating
There’s no shortage of oys in the world but Jewish News takes every opportunity to celebrate the joys too, through projects like Night of Heroes, 40 Under 40 and other compelling countdowns that make the community kvell with pride.
Pioneering
In the first collaboration between media outlets from different faiths, Jewish News worked with British Muslim TV and Church Times to produce a list of young activists leading the way on interfaith understanding.
Campaigning
Royal Mail issued a stamp honouring Holocaust hero Sir Nicholas Winton after a Jewish News campaign attracted more than 100,000 backers. Jewish Newsalso produces special editions of the paper highlighting pressing issues including mental health and Holocaust remembrance.
Easy access
In an age when news is readily accessible, Jewish News provides high-quality content free online and offline, removing any financial barriers to connecting people.
Voice of our community to wider society
The Jewish News team regularly appears on TV, radio and on the pages of the national press to comment on stories about the Jewish community. Easy access to the paper on the streets of London also means Jewish News provides an invaluable window into the community for the country at large.
We hope you agree all this is worth preserving.
