“Look up,” renowned astrophysicist Neil deGrasse Tyson urges.

Now, during World Space Week, planetary scientists are doing just that — and much more.

Though professor Paul Kamoun is on planet Earth, heading the space technology and remote sensing laboratory at Jerusalem College of Technology, his gaze has drifted upward for the past 40 years.

Climate change, drug development and Israel’s moon mission are just three areas that keep his eyes trained on outer space.

With a PhD in earth and planetary sciences from the Massachusetts Institute of Technology, the French-born Kamoun worked on more than 150 projects with NASA, European space agency ESA and French space agency CNES.

He handles international business development for Swiss company SpacePharma, whose miniature made-in-Israel laboratories take advantage of gravity-free outer space for the development of new drugs.

He was also an independent telecommunications consultant for the privately funded SpaceIL Beresheet spacecraft to the moon in April 2019, which crash-landed, and hopes to send an experiment aboard Beresheet 2 in 2024.

Perhaps most urgently, Kamoun is studying the causes and consequences of climate change using satellite imagery.

Who and what are responsible?

It has been documented that mass industry and fossil fuels play a role in consequences such as global warming and polar ice cap melting, Kamoun said.

However, what’s not known is the extent of manmade causes or how they compare to natural causes such as the sun’s cycle, the Earth’s behavior and the interaction between the atmosphere and the ocean.

“There is no doubt that there is global warming. But we don’t have enough data to quantify the causes with scientific accuracy. We need to accumulate about 30 years of satellite data to do that, and we have about 15 years of data so far,” Kamoun said.

“We are not able to say that the contribution of man to global warming is exactly this or that. If we had that data in our hands, all the countries of the world would more likely reach a consensus about what to do,” said Kamoun.

He encourages his students to design next-gen satellites to discover more about the Earth and space, and how to use satellite data to improve our world.

Big technology, small budget

Advanced space technologies are a specialty in Israel, despite its modestly funded space program.

“NASA has huge budget of more than $23 billion for 2021, while Europe altogether has about a $5 billion yearly space budget, and Israel… maybe $20 million,” Kamoun said. “What can you do with that kind of budget? You can make great technology for space programs, both inside and outside Israel.”

For example, he said, Ramon Space is developing high-power processors for supercomputing in space. Elbit Systems is developing highly advanced electro-optics solutions for space among other applications.

“It’s hard to compare the number of satellites or space missions with players like NASA, but you can compare the technology — and ours is top level,” Kamoun said.

Israeli scientists have had fruitful collaborations with NASA, he said, “although not as much as could be done and not very visible.”

NASA provided, for instance, important means of communication for Beresheet 1. And many Israeli scientists are collaborating with U.S. counterparts to prepare NASA’s future moon and Mars missions, he said.

Some of Kamoun’s graduate students are examining digital satellite images from VENuS, the first cooperative Earth observation program of the Israel Space Agency and France’s CNES.

The uses of such imagery are almost endless, said Kamoun. For now they are focused on identifying the evolution of vegetation and water in northern Israel.

Plans for Israel’s next moon mission

Kamoun hopes to have his students design physics and electro-optics experiments for Beresheet 2, which will include two ultralight lunar landers and an orbiter that will circle the moon for several years and host experiments from students.

One possibility is an onboard physics experiment relating to Einstein’s theory of relativity.

“Another idea is to design and attach a small camera or sensor on the landers, to help find the best place to land during descent and then to take images during and after landing,” said Kamoun.

He will have to scramble to make SpaceIL’s November deadline for proposals for experiments to fly on Beresheet 2.

“It’s complicated: You need to find a good scientific case, design the right instrumentation to solve the scientific question, and find the funding for it. Usually governments take care of the money. But in privately funded missions like Beresheet, financing is as tricky as the science project itself,” he said.

First drug factory in orbit

Kamoun’s experiences in space programs of the United States, Europe and parts of Asia made him the natural choice to lead international business development for SpacePharma.

Based in Switzerland with R&D and business development in Israel, SpacePharma capitalizes on the fact that the physical, chemical and biological conditions in space offer unique conditions for drug development.

SpacePharma’s portable lab allows big pharma and independent scientists alike to develop experiments and products in space.

“It’s already been in space five times, and we have two more missions coming up in the next five months, including one with Israeli astronaut Eytan Stibbe,” said Kamoun.

Stibbe is expected to take 44 experiments on next year’s mission to the International Space station, from fields including agriculture, neurology and optics.

“SpacePharma is also developing the first drug factory in orbit, which should be launched in the end of 2023,” said Kamoun. “It will be the first building block of our larger-scale space factory for drugs. It will be a fantastic paradigm change for developing new drugs faster and even cheaper than on Earth.”

He said he cost of R&D in outer space is becoming compatible with the skyrocketing cost of R&D on Earth.

Will Kamoun ever have a chance to enter outer space himself?

“It is naturally a dream to go to space to see our beautiful Earth from far and to see the marvelous planets of the solar system from close,” he said. “But except for a few lucky or wealthy guys, this will be most probably for the generation of our students and children — if, of course, the technology and most importantly the reliability of human space flight progress enough.”
