NASA has confirmed preparations for the launch of mission Dragonfly, a nuclear-powered drone intended to explore Titã, the largest moon of Saturno, scheduled to depart in 2028. Simultaneamente, the American company NRD has presented a new line of nickel-63 nuclear batteries capable of providing electricity for more than a century without need for maintenance. Essas innovations coincide with the publication of a geological study that identifies volcanic processes responsible for large concentrations of gold in the Earth’s mantle. The convergence between deep space exploration and the development of long-duration energy sources signals a new phase in consumer technology and scientific research.
NASA uses nuclear drones to investigate life on Titã
Project Dragonfly consists of an octocopter-type aircraft that should reach the atmosphere of Titã in 2034 to carry out studies on the satellite’s prebiotic chemistry. The vehicle is equipped with a multi-mission radioisotope thermoelectric generator, known as the MMRTG nuclear battery, which guarantees the operation of the systems at temperatures of up to -180 °C. The central objective is to investigate whether the moon of Saturno has conditions that favored the emergence of life in the past or present.
The aircraft will carry out alternating flights to collect samples in different regions, starting with the dunes of Shangri-La and continuing to the crater Selk. Entre The scientific tools installed include high-resolution cameras and a mass spectrometer to analyze the organic composition of the soil. The strategy of using a drone allows NASA to explore a much larger area than would be possible with a conventional static lander.
Nickel-63 batteries promise continuous power for a century
The NRD company presented the NBV series, made up of non-volatile nuclear batteries that use the nickel-63 isotope to convert beta decay into electricity. Esses devices are designed for ultra-low power electronics, making them ideal for applications where battery replacement is impractical. The solid, sealed structure ensures the safety of radioactive material while providing a stable current for approximately 100 years.
The batteries have compact dimensions of 20 x 20 x 12 mm, with a power range that varies between 5 and 500 nanowatts. The innovative design focuses on systems that require high reliability in harsh environments, such as security sensors and remote environmental monitoring. The technology represents a milestone in the use of nuclear materials for next-generation civil and industrial solutions.

Geological study reveals origin of gold reserves in volcanoes
Researchers recently published a discovery about Terra’s so-called “golden kitchen,” located in volcanic arcs like the Kermadec region. The study details how repeated melting of the Earth’s mantle at high temperatures releases gold contained in sulfide minerals into the magma flow. Esse The repetitive melting process is what explains why certain volcanic zones have concentrations of the metal much higher than those found in other oceanic areas.
Although the deposits identified on the seabed do not have immediate economic viability for extraction, research is essential to understand the geochemical evolution of the planet. Data shows that sulfur plays a critical role in transporting precious metals from deep into the crust. Essa Gold’s complex journey before reaching the surface helps predict the location of deposits on solid ground.
Technical specifications of mission Dragonfly and NBV batteries
Technological integration between new nuclear energy sources and planetary exploration requires precision in technical data and schedules. NASA has already started the testing and assembly phase of Dragonfly in Laboratório of Física Aplicada of Universidade Johns Hopkins. Abaixo, the main components and deadlines established for these technologies are listed:
- Dragonfly Release:July 2028via SpaceX rocket Falcon Heavy.
- Arrival at Titã: Prevista to2034.
- Instrumentation: Espectrômetro mass, meteorological sensors andeight rotors.
- Battery voltage NBV: Faixa1.0V to 20.0V.
- NBV dimensions:20mm x 20mm x 12mm.
The convergence of these advances indicates that energy autonomy will be the cornerstone of the coming decades both in space and in critical terrestrial infrastructures. The stability promised by nickel-63 and the thermal resistance of Dragonfly are examples of how nuclear engineering is being adapted to extreme challenges.
