We develop breakthrough antigravity propulsion, a 30cm small 20kg lightweight - fission-annihilation antigravity propulsion, with a thrust of 100 tons (can run multiple years), which accelerates on Mach9 in the atmosphere, in space to light-speed ( can be in 1 day on Mars, 2 years (dilated time of astronauts) to anywhere in the galaxy). Our technology is 10 times cheaper than a chemical rocket, 1000 times with repeated use. Our technology is verified in secret military projects. www.1-space.eu
