NASA’s JunoCam, once believed nearly lost to Jupiter’s intense radiation, has made a stunning comeback thanks to a bold experiment. Engineers used a process called annealing—heating the camera from afar—to reverse internal damage and restore image clarity. Just in time for a close flyby of the volcanic moon Io, the camera delivered detailed images of lava flows and sulfuric peaks. The breakthrough technique is now being applied to other instruments on Juno and could shape future spacecraft built for radiation-heavy environments around Earth and beyond.

A growing number of rocket launches may be compromising the ozone layer’s recovery, according to new scientific studies. Chlorine and soot from rockets, along with pollutants released during satellite re-entry, could have long-term environmental impacts. The space industry is urged to act now—through regulation, innovation, and cleaner fuels—to protect one of Earth’s vital protective layers.

The revelation that Mars once had Earth-like rainfall reshapes our understanding of planetary evolution. The insights support the theory that early Mars was far more hospitable than previously believed, possibly housing primitive life forms. The findings could guide future missions like NASA’s Perseverance in locating signs of fossilised organisms.
