Japan tests a combined cycle jet and rocket engine. We are getting close to Macross irl with exo-atmospheric fighter jets.

I don't know how this is related to GCAP, and it mostly isn't. It's a Japanese new space news.

On August 30, 2024, the Ministry of Defense announced its budget request for fiscal 2025. Among them, we learned that 323.2 billion yen was requested for the construction of a “satellite constellation” using small satellites.

It is expected that satellite launches will begin at the end of FY2025, and the constellation will be built gradually, with full-scale operations to begin at the end of FY2027.

The Ministry of Defense plans to use the satellite as an “eye” to detect and track enemy naval vessels, ground forces, etc., in a stand-off defense capability to neutralize the enemy from a long distance using long-range missiles. In addition, a budget of 5.3 billion yen has been requested for the “Tactical AI Satellite Demonstrator Prototype,” which will use AI to process enemy data captured by other satellites and provide enemy information through intercommunication with various types of equipment.

Developed by the Japanese space agency JAXA, the spacecraft will explore Phobos from orbit and collect samples from its surface. On board MMX is the IDEFIX rover – a collaboration between the German Aerospace Center (DLR) and the French space agency CNES.

IDEFIX will land on Phobos, analyse its surface properties and help select a suitable landing site for the MMX mothership.

The MMX mission is scheduled to launch from Japan’s Tanegashima Space Center in 2026.

This animation shows the planned mission timeline – from the journey to Mars and its moons, the exploration of Phobos from orbit and on the surface with the IDEFIX rover, to the sample collection by the mothercraft and its return to Earth.

The Japanese MMX (Martian Moons Exploration) mission will launch in October 2026 to study Mars' two moons, Phobos and Deimos. A small Franco-German mobile robot named IDEFIX, operated by CNES and DLR, will be dropped on Phobos as a scout to characterize the Martian moon's surface. The FSS (Farside Seismic Suite) seismometer will be placed on the far side of the Moon in 2026, near the south pole in the Schrödinger Basin, an ancient impact crater that bears traces of a volcanic eruption half a billion years ago. This is a cooperation with the United States and its launch is scheduled for June 2026.
