WASHINGTON — A French startup has raised an preliminary spherical of funding to start testing of solar sails it believes can sharply cut back the price of deep area missions.
Paris-based Gama introduced March 22 it raised 2 million euros ($2.2 million) in seed funding to begin work on solar sails, together with an illustration mission it plans to launch in October. The funding got here from the French public funding financial institution BPI, the French area company CNES and a number of other personal buyers.
The funding will enable the corporate to full its first spacecraft, Gama Alpha, which is scheduled to launch in October on a SpaceX rideshare mission. The six-unit cubesat, utilizing a bus supplied by NanoAvionics, will take a look at the deployment of a solar sail with an space of 73.3 sq. meters.
Andrew Nutter, a co-founder of Gama, mentioned in an interview that the first goal of Alpha is to take a look at the sail’s deployment mechanism. “We’re employing a spin-sail solution,” he mentioned, slowing rotating the satellite tv for pc and utilizing centrifugal power to deploy the sail. “This allows us further down the line to have much larger surfaces and reduce costs.”
The method does away with the necessity for booms to deploy and stabilize the sail. LightSail 2, a solar sail demonstration by The Planetary Society launched in 2019, used booms to deploy its sail. “We’ve tried to learn as much as possible from what they’ve done and see where we can improve things,” he mentioned.
Alpha gained’t generate any measurable thrust due to the atmospheric drag from its low orbit. “We’ll be launched to 550 kilometers, which will be too low to really be able to prove thrust in any meaningful way,” he mentioned. A second mission, deliberate for launch by early 2024, will go to the next orbit of a minimum of 800 kilometers to generate thrust and take a look at controls of the sail.
Gama believes its sails may also help area businesses develop low-cost missions by making the most of the flexibility of sails to generate thrust repeatedly with out propellant. “The vision is to dramatically reduce the cost of deep space exploration,” Nutter mentioned. The focus is on science missions, he mentioned, “because there are still significant budgets for scientific exploration, especially if you can reduce the cost by 10, 50, 100 times.”
Early targets for missions propelled by Gama’s sails embody spacecraft going to Venus or to asteroids. The firm’s roadmap of missions consists of one known as Gamma that may go to Venus as quickly as 2024. “Venus is kind of the North Star for the company and it gets us very excited,” he mentioned, “but I think we’ll have to adapt to the opportunities when we discuss them with our scientific partners.”
The firm can be taking a look at business functions of its solar sails. Such sails, he mentioned, may enable spacecraft to sit over the poles or function in “displaced” geostationary orbits a bit above or beneath the geostationary arc.
Nutter and his two co-founders, Louis de Gouyon Matignon and Thibaud Elziere, leveraged their contacts from previous companies in different sectors to line up this preliminary funding spherical. “The objective for us was just to find a group of people we consider friends who have built businesses in the past and who are very excited about space and what we’re trying to achieve,” he mentioned.
He mentioned that it’s turning into simpler for area startups in Europe to increase cash as enterprise capital funding will increase, creating new alternatives. “In terms of engineers, France and Europe have a huge talent pool,” he mentioned. “If you compare costs to an engineer in California, it’s a fraction of the cost.”
“There’s much more commercial opportunity, and huge amounts of funds coming into Europe,” he mentioned. “Fundraising beyond a certain level is always difficult, but I’m very confident that we’ll continue to fundraise.”
