Japan Launches World’s Smallest Rocket

A year after its tiny, experimental rocket failed to reach orbit a year ago, the Japanese Aerospace Exploration Agency (JAXA) successfully launched an experimental rocket into orbit this weekend, the smallest ever to do so. According to JAXA, the launch was a demonstration experiment, that carried the TRICOM-1R — a three-unit cubesat — into lower Earth orbit, where it will observe the Earth with a set of cameras. Now in orbit, JAXA says that its status is “nominal,” The Verge reported. With its successful launch, the SS-520-5 is the smallest rocket to ever deliver a satellite into orbit. The vehicle is a SS-520 sounding rocket that has been modified with a third stage, which helped bring the satellite into orbit. The mission is part of a movement in the space industry towards using smaller vehicles to deliver tiny payloads. New Zealand company Rocket Lab successfully launched its first small rocket called Electron last month, delivering four satellites into orbit, including the disco ball-shaped Humanity’s Star.
