OSIRIS-REx makes closest Earth approach today
... – Regolith Explorer will pass the Earth around 17,000 kilometres above us in order to perform a manoeuvre known as an Earth Gravity Assist. Along with saving fuel, this manoeuvre allows the spacecraft to ’borrow’ a small amount of Earth’s orbital...

ESA's Solar Orbiter mission set to launch on 10 February
... to be ‘in resonance’ with Venus, meaning it will return to the planet’s vicinity every few orbits so that it use Venus’ gravity to alter or tilt its orbit. Data gathered by Solar Orbiter will be stored on the spacecraft, then ‘downlinked’ (or beamed...

World's first firing for ESA's air-breathing electric thruster
... to propel it through the atmosphere. The thruster builds on the work already undertaken by ESA for their GOCE gravity-mapper satellite. GOCE also utilised an electric thruster design, but it was fuelled by xenon atoms that had...

Innovative mission to view the surface of exoplanets using small sats
... at JPL and Aerospace might one day show us just that as they are working on plans for a solar gravity lens (SGL) – a cluster of small sats which act like a lens to provide up to a 100-billion optical magnification – this...
