The spinning, solar-powered spacecraft will take another look of the fiery Jovian moon on July 30.

When NASA's Juno mission flies by Jupiter's fiery moon Io on Sunday, July 30, the spacecraft will be making its closest approach yet, coming within 13,700 miles (22,000 kilometers) of it.

NASA and the US military said Wednesday they had selected defense contractor Lockheed Martin to develop a nuclear powered rocket, with a view to using the technology for missions to Mars.

The Demonstration Rocket for Agile Cislunar Operations (DRACO) program may launch as soon as 2027, officials said on a call.

Nuclear thermal propulsion (NTP) systems could cut journey times, increase fuel efficiency, and require less propellant, meaning future spacecraft could carry larger payloads than today's best chemical rockets.

NTP works by pumping a liquid propellant, in DRACO's case cryogenic hydrogen, through a reactor core, where uranium atoms split apart through fission.

Space is a dangerous place. From micro-meteorites and electromagnetic interference to fires in space and extreme heat and cold, we need to develop new materials to enable the next generation of space travel and intergalactic travel.

New Swinburne research published in Advanced Composites and Hybrid Materials highlights the cutting-edge materials that are solving these problems, including those being developed by Swinburne's Multifunctional Materials and Composites team.

These include self-healing polymers, fire and thermally resistant materials, materials for thermal management, self-cleaning materials, EMI shielding materials and multifunctional carbon fiber composites.
