Android Launchers

At this week's DSEI Defence exhibition in London, SpearUAV unveiled its Multi Canister Launcher (MCL) Viper system, which is bolted onto the outside of conventional and robotic military vehicles to launch Viper drones without exposing soldiers to harm.

Rockets are expensive, so a number of kinetic launch startups are working on ways to simply yeet payloads into orbit and bring costs down. This one's very fun – a six-mile-long concrete cannon that'll squeeze launch vehicles to Mach 30 in one second.

Green Launch says it can fire a space vehicle skywards three times faster than SpinLaunch's kinetic launch system. Its huge hydrogen gas cannon can produce hypersonic launch velocities upwards of Mach 17, enabling orbital altitudes up to 1,000 km.

NASA has signed up to test SpinLaunch's extraordinary whirl 'n' hurl space launch technology, which accelerates a launch vehicle to hypersonic speeds using an electric centrifuge arm instead of a rocket, hurling it skyward like a space discus.

Startup SpinLaunch has been exploring alternatives to rockets through the development of what it calls the world's first kinetic space launch system, which literally flings satellites into orbit – and it's recently completed its first test flight.

Virgin Orbit continues to edge closer to its objective of firing satellites into space form an airborne 747, this time completing an end-to-end launch rehearsal designed to put all of its systems through their paces.

Engineers have mated the fourth and final Space Shuttle-era engine to the core stage of NASA’s first Space Launch System Moon rocket. NASA hopes to use the super heavy launch vehicle to return astronauts to the Moon before striking out for Mars.

One of the best things about Android is the ability to quickly and easily customize the experience to suit your preferences. Launchers provide a quick and easy way to do this, often drastically altering the look and feel of a device.

Facebook has pulled back the curtain on its Android launcher screen replacement, Facebook Home.

XP Mod is an Android Launcher, or home screen replacement, that recreates the look and feel of Windows XP.
