THE future of NASA may be in doubt after a shortage of plutonium, which is needed for deep space missions, was uncovered by US officials.
Donald Trump’s Government Accountability Office (GAO) warned that space agency’s future may at risk as the US Department of Energy “faces challenges meeting NASA’s expected need” for a plutonium isotope required for missions.
The GAO revealed in its latest report around half of the US’s plutonium stockpiles were already in use and the future missions Mars 2020 and New Frontiers Number 4 could diminish the remainder.
Without access to the Pu-238 radioisotope, NASA “will be forced to eliminate or delay future missions” – including the space agency plans to send astronauts to Mars between 2030 and 20140.
Shelby S Oakley, director of acquisition and sourcing management at GAO, said: “If the Energy Department's existing Pu-238 supply is used for these two missions, NASA would be forced to eliminate or delay future missions.”
The news comes as NASA scientists had hoped to send spacecrafts to explore hidden oceans on moons of Jupiter and Saturn and travel further into deep space to uncover the secrets of the universe.
Alan Stern, the lead scientist on NASA’s the New Horizons mission said: ”All of these missions would require nuclear power.”
Jessica Sunshine, a scientist who developed a comet-hopper mission for Nasa, told Business Insider that without plutonium missions like hers will also come into question.
She said: ”It's not a matter of can you do it better, but can you do it at all.
"On a comet, operating at crazy distances, you can't land with solar panels the size of an Airbus wing. A radioactive power supply is a totally enabling thing."
