"Japan also needs to acquire the technology to enhance its international competitiveness."Reusable rockets and engines can significantly reduce the costs to launch satellites into orbit. European countries and the United States have taken the lead in developing such technology.JAXA's rocket for the test is 7 meters high and weighs 2 tons. It will take off via the 4-ton thrust force created by an engine that mixes and burns liquid oxygen and liquid hydrogen.Under the plan, the test launch in March 2019 will send the rocket to about 100 meters in altitude. The rocket will then return to Earth and land vertically on its base.JAXA plans another test launch to about 5 kilometers in altitude in the latter half of fiscal 2019.During the course of the project, JAXA is scheduled to conduct a fuel-burning test in a facility located in Noshiro, Akita Prefecture. The test will check the durability of the engine, which will be repeatedly exposed to high temperatures during the flights.СпойлерU.S. venture company SpaceX slowly landed a large-sized rocket and recovered it intact in 2015. The company in 2017 launched the recovered rocket, carrying a commercial satellite.Another U.S. company, Blue Origin, has also succeeded in reusing a rocket.The European Space Agency is developing reusable rocket engine prototypes.[свернуть]JAXA has been researching reusable rocket engines since the late 1990s.With the testing project, JAXA is looking beyond the next-generation H-3 rocket, which is scheduled to be launched for the first time in fiscal 2020.

Ground tests are already underway, and flight tests are scheduled for next year!

Once the rockets reach a height of 100 meters above ground, they will be controlled to hover, move sideways and land.In 2022, JAXA plans tests with a larger Callisto rocket that will reach an altitude of 30 kilometers before returning to near its original launch site or an offshore platform. Japan plans to partner with Germany and France on the project, which is expected to cost over 15 billion yen, as securing a site is likely to be difficult....
