Janus - misja do podwójnej planetoidy NEO

[ekoplaneta]

Razem z sondą do planetoidy Psyche w rakiecie Falcon Heavy w 2022 roku leci nowa misja marsjańska Escape and Plasma Acceleration and Dynamics Explorers oraz misja do badania podwójnej planetoidy NEO:

Misja odwołana.
Z powodu opóźnień w starcie cel za bardzo zmienił pozycję w US, by był dostępny dla misji Janus.
Obecnie sondy przygotowywane są do dłuższego magazynowania.

After spending nearly $50m on development, NASA has canceled the Janus smallsat asteroid mission.
Janus was to launch with NASA's larger Psyche probe, which was delayed more than a year due to issues with software testing. That meant Janus lost its ride.

Janus was designed to fly to two binary asteroids—consisting of two bodies near one another—that orbit the Sun closer to Earth than the metallic asteroid Psyche. While the Psyche mission can still reach its asteroid destination and accomplish its science mission with a launch this year, the asteroids targeted by Janus will have changed positions in the Solar System by too much since last year. They are no longer accessible to the two Janus spacecraft without flying too far from the Sun for their solar arrays to generate sufficient power.
