 "Elon Musk’s Mars Nuclear Plan: Controversy & Reactions")
In September 2015, Elon Musk, speaking on a television program, proposed detonating thermonuclear charges on the poles of Mars in an effort to warm the planet and rapidly vaporize the dry ice covering its surface. The suggestion immediately drew criticism and concern from international actors.
Dmitry Rogozin, then head of the Russian space agency Roscosmos, characterized Musk’s proposal as a cover for the deployment of nuclear weapons in space, and hinted at a retaliatory capability. “Musk’s proposal to blow up Mars with nuclear weapons is a pretext for deploying nuclear weapons in space,” Rogozin stated at the time, according to reports.
Musk revisited the idea of detonating nuclear charges on Mars more recently, according to Bulgarian news outlet Telegraph. The renewed discussion comes as Musk’s ambitions for Martian colonization continue to evolve, though timelines for achieving those goals have shifted.
However, the feasibility of Musk’s plan has been questioned by scientists. Vyascheslav Turyshev, a leading researcher at NASA’s Jet Propulsion Laboratory, has stated that the idea, while “cool,” is not an engineering solution. Turyshev explained that even if all the carbon dioxide on the Martian poles were melted, it would still be insufficient to create a stable atmosphere and liquid water. He cited calculations indicating that the planet’s available gas reserves are too small, and releasing them would require a colossal amount of energy. “The idea is cool, but it is not an engineering solution,” Turyshev said in an interview with RTVI, as reported by multiple news sources including Novini.bg and Petel.bg.
Turyshev further elaborated that even accounting for the sublimation of polar CO2, the accessible underground reservoir is estimated at approximately 6 mbar (600 Pa) or around 2.3 × 10 kg, a quantity insufficient for substantial atmospheric creation.
NASA has publicly expressed skepticism regarding the effectiveness of such explosions. The agency’s assessment, as reported by Novini.bg and Telegraph, suggests that the proposed detonations would be largely ineffective in achieving the desired outcome of a habitable Martian atmosphere.
As of March 12, 2026, Musk has not publicly responded to the latest criticisms of his plan, and NASA has maintained its position that the proposal is not a viable path toward Martian terraforming.
