Reusable rocket
A planned reusable rocket sized like SpaceX's Falcon 9, likely with a wider fairing, carrying up to 20 tonnes. RATLOG targets a flight-ready engine in 2027, a hopper test in 2028 and a first launch in 2029 or 2030.
Why it matters
A much simpler engine could make a reusable rocket cheaper to build and fly. RATLOG is at a very early stage, with four people and grant funding.
How the technology works
Most large rocket engines use a turbopump, a complex high-speed machine, to force propellant into the combustion chamber. RATLOG's engine instead rotates as a whole to build pressure, which the company says removes about 90 percent of the parts.
It is considering launch sites in Oman and the UAE.
