The Jupiter and Trojan Asteroid Explorer is a cancelled Japanese JAXA mission that was proposed to have flown with the also cancelled Jupiter Magnetospheric Orbiter (JMO). Originally, it was intended as part of the Europa Jupiter System Mission - Laplace.

The craft was initially planned to use a solar sail and release the JMO orbiter in 2025 upon arriving in the Jovian system.[1]

In November 2013, Japan's JAXA scientists stated that ″it turned out that a relatively low-cost solar power sail could not transport a magnetosphere orbiter with enough science payload in mass and size. Orbits around Jupiter would be restricted.″ [2]
