Skyfall is occurring, and it’ll get to Mars in a very new approach.
Final summer season, NASA’s Jet Propulsion Laboratory and the Virginia firm AeroVironment unveiled their Skyfall mission idea, which might ship six tiny helicopters to discover the skies of Mars.
In the present day (March 24), NASA introduced that it’s going to develop Skyfall for a 2028 launch, and that the mission will journey to the Pink Planet on a spacecraft that makes use of nuclear electrical propulsion (NEP) — what NASA is referring to as “the primary nuclear powered interplanetary spacecraft.”

NEP methods function like nuclear energy vegetation right here on Earth, counting on an onboard fission reactor. NEP is a basically completely different expertise than radioisotope thermoelectric turbines (RTGs), which have powered the instruments of NASA deep-space probes like Voyager for decades. RTGs use the heat of radioactive decay to generate electricity; they are not involved in propulsion.
“Requiring operating temperatures less than nuclear thermal propulsion, the thermal energy produced by the reactor generates electricity, which is then used to power highly efficient electric thrusters,” NASA officials wrote in a description of the company’s NEP efforts.
NASA views NEP tech — which may function in any respect distances from the solar — as key to its future exploration efforts, from robotic missions to the outer photo voltaic system to the operation of a moon base through its Artemis program.
So the centerpiece of the Skyfall mission is probably not its fleet of Mars helicopters however somewhat their interplanetary trip — a spacecraft referred to as Area Reactor-1 (SR-1) Freedom.
“SR-1 Freedom will set up flight-heritage nuclear {hardware}, set regulatory and launch precedent, and activate the commercial base for future fission energy methods throughout propulsion, floor and lengthy‑period missions,” NASA officers stated in the present day in a statement saying the mission.
“NASA and its U.S. Division of Vitality associate will unlock the capabilities required for sustained exploration past the moon and eventual journeys to Mars and the outer photo voltaic system,” they added.
That assertion contains a wealth of different exploration information and updates. For instance, NASA additionally introduced in the present day that it is pausing its long-planned Gateway moon-orbiting area station to concentrate on constructing a base on the lunar floor — and a few of Gateway’s {hardware} will go into the development of that outpost.
That statement doesn’t reveal many details about the planned Skyfall mission, but AeroVironment gave us some during the unveiling last summer.
“Skyfall is designed to deploy six scout helicopters on Mars, where they would explore many of the sites selected by NASA and industry as top candidate landing sites for America’s first Martian astronauts,” AeroVironment said in a July 24 statement.
These helicopters will likely be much like Ingenuity, the little NASA rotorcraft that landed on the Pink Planet with the Perseverance rover in February 2021. Ingenuity turned the primary helicopter ever to function on a world past Earth, making a whopping 72 flights between April 2021 and January 2024.
Whereas Ingenuity was a expertise demonstrator, nonetheless, the Skyfall fleet may have concrete science and exploration duties.
“Whereas exploring the area, every helicopter can function independently, beaming high-resolution floor imaging and sub-surface radar information again to Earth for evaluation, serving to guarantee crewed autos make secure landings at areas with most quantities of water, ice, and different sources,” AeroVironment representatives stated in final summer season’s assertion. “The information Skyfall collects might additionally advance the nation’s quest to find whether or not Mars was ever liveable.”
