Juno

The White House budget proposal suggests canceling NASA missions including ExoMars, New Horizons, Juno, Mars Odyssey, and MAVEN.

The RDRE is a next-generation propulsion system developed by Juno Propulsion under NASA's Space Technology Payload Challenge.

The Rotating Detonation Rocket Engine (RDRE) was developed by Juno Propulsion and was selected in the NASA payload challenge.

Juno is also making progress in exploring Jupiter's faint rings and continues mapping its strong magnetic and gravitational fields.

Juno does not fall under the protected categories for continued operation during the shutdown.

NASA's Juno spacecraft is still operational at Jupiter.

Juno's first extended mission began in August 2021 and ended in September 2025.

The White House budget proposal for fiscal year 2026 included cuts to Juno's funding.

Juno has conducted flybys of moons such as Ganymede, Europa, and Io, providing data on geology, environment, and composition.

A second extended mission for Juno may start in October 2025.

Juno's X-Band transmitter was successfully received at a distance of 781 million kilometers using the Bochum 20m antenna.

Juno was launched in 2011 and entered Jupiter's orbit in 2016.

JUNO contains 20,000 tons of specialized liquid scintillator in a 40-meter sphere surrounded by more than 17,000 photomultipliers.

The JUNO project benefits from longstanding involvement by CNRS in design, construction, commissioning, and data exploitation.

JUNO's data will also contribute to understanding astrophysical phenomena like supernovae.

JUNO's tank is situated inside a water pool and beneath a Top Tracker system that filters stray cosmic particles that might mimic neutrino signals.

The JUNO collaboration involves 74 institutions across Asia, Europe, and the Americas.

JUNO is expected to deliver the most sensitive measurements of neutrino signals ever achieved.
