The company wants to one day build superfast commercial jets using this new type of engine. In a 24 February test flight, the company flew the drone, which is 2.4 metres long and weighs 136 kilograms, to an altitude of 3,658 metres with an Aero L-29 Delfín plane before it was deployed and the RDRE was activated. The drone flew ten miles at Mach 0.9 – over 680 miles per hour – using 80 per cent of the RDRE’s available thrust. The flight proved the viability of RDRE and the associated onboard flight systems. Three weeks earlier, Venus Aerospace demonstrated the viability of its RDRE technology with a long-duration test burn, during which engineers showed their engine worked for the duration of this test flight.

The Space Force is launching lasers into orbit
The Space Force aims to better pinpoint the location of Earth's true centre using lasers on GPS satellites, slated to launch in 2025. A set of Laser Retroreflector Arrays, or LRAS, will be installed onto two GPS III satellites, SV9 and SV10, as part of NASA's Space Geodesy Program. The lasers are designed to make precise sub-centimetre measurements using a technique called Satellite Laser Ranging, which will allow researchers to more accurately determine Earth's centre.
Eating too much sugar may accelerate cellular ageing
A nutrient-rich diet with few added sugars may slow the rate of biological ageing in women. Scientists found that middle-aged women who ate more foods packed with vitamins, minerals and antioxidants had 'younger looking' cells than those who consumed less nutrient-rich diets.
