During a ceremony that celebrated the youngest researchers, the Russian president, Vladimir Putin, engaged in a practical, and at times playful, conversation about space safety. He asked whether the newest radiation shielding technologies could support a mission to Mars and even considered testing them with animals such as a cow, a rabbit, or a cat to illustrate potential scenarios. The moment came as the event highlighted the achievements of rising scientists and engineers across the country.

Natalya Igorevna Cherkashina, an engineer responsible for astronaut protection, outlined the strides being made to shield crews and equipment from space radiation. She showcased how lightweight, durable protective composites are being developed and tested, alongside approaches for active shielding that could be evaluated in laboratories and simulated missions designed to mimic real space conditions.

Putin pressed for specifics on whether today’s shielding materials could enable a round trip to Mars or sustain life during a transit for animals used in experiments. Cherkashina explained that researchers are tackling exposure from galactic cosmic rays and solar particle events, while also balancing weight, propulsion needs, and mission feasibility so that shielding does not become a barrier to exploration.

The engineer noted ongoing efforts to enhance protection as crews prepare for longer missions. The discussion touched on the challenging reality that a Mars voyage would take roughly six months, a timeframe that exposes astronauts to radiation levels far beyond those encountered in low Earth orbit. The exchange underscored the practical tradeoffs between shielding effectiveness, mass, and the limits of current propulsion systems.

At the same ceremony, Putin commented on the flow of scientists leaving the country and the number returning, pointing out that the outflow remains relatively modest. He indicated that approximately five to seven percent of researchers pursue opportunities abroad, with a similar share eventually returning to contribute to Russia’s scientific community.

Putin affirmed that the nation’s talented scientists and experts will continue to have the conditions needed to realize their potential at home. He stressed the importance of sustaining an environment where the next generation of researchers can grow, innovate, and carry forward Russia’s scientific leadership from within its borders.

Previously, the ceremony recognized the winners of the President of the Russian Federation award in science and innovation for young scientists, a set of honors that underscored the country’s ongoing investment in emerging talent and the future of its research landscape.
