Every day the RIME antenna shows more signs of movement, visible in images from the Juice Monitoring Camera on board the spacecraft with a partial view of the radar and its install. Now partly extended however still stowed away, the radar is approximately a 3rd of its full designated length.
Juices stuck but moving RIME antenna is caught by the Juice Monitoring Camera on board the spacecraft. 4 sections of the RIME antenna are visible here, folded on top of each other. The other half has actually not yet begun deployment and ends up being noticeable through the broadening gaps in between antenna segments.
The present leading hypothesis is that a small stuck pin has not yet made method for the antennas release. In this case, it is believed that just a matter of millimeters could make the difference to set the remainder of the radar free.
Various alternatives are still available to nudge the essential instrument out of its existing position. The next actions to totally deploy the antenna consist of an engine burn to shake the spacecraft a little followed by a series of rotations that will turn Juice, heating up the mount and radar, which are currently in the cold shadows.
Quickly after launch on April 14, ESAs Jupiter Icy Moons Explorer, Juice, recorded this image with its Juice keeping track of electronic camera 2 (JMC2). JMC2 is situated on the top of the spacecraft and is put to keep track of the multi-stage deployment of the 16 m-long Radar for Icy Moons Exploration (RIME) antenna. RIME is an ice-penetrating radar that will be utilized to remotely penetrate the subsurface structure of the large moons of Jupiter. In this image, RIME is seen in stowed setup.

Juice is otherwise carrying out excellently after the successful deployment and operation of its mission-critical solar varieties and medium gain antenna, along with its 10.6-m magnetometer boom.
With two months of planned commissioning remaining, there is plenty of time for teams to get to the bottom of the RIME deployment issue and continue deal with the remainder of the effective suite of instruments on their way to investigate the external Solar System.

RIME is an ice-penetrating radar that will be used to remotely probe the subsurface structure of the large moons of Jupiter. Discharged by a 16-m long dipole antenna, the radar signals will penetrate the icy surface areas of the moons to a depth of 9 km, offering a vertical resolution in between 50 and 140 m.

Updates will be shared as new details becomes readily available.
The RIME instrument is an ice-penetrating radar created to study the surface area and subsurface structure of Jupiters icy moons down to a depth of 9 km.
It is among 10 instruments on board ESAs Jupiter Icy Moons Explorer, Juice, set to examine the emergence of habitable worlds around gas giants and the formation of our Solar System.

The Radar for Icy Moons Exploration (RIME) antenna on ESAs Jupiter Icy Moons Explorer (Juice) spacecraft has actually experienced a problem preventing its deployment. The 16-meter-long antenna, crucial for studying the surface area and subsurface structure of Jupiters icy moons, is presently stuck in its mounting bracket due to a presumed small pin. Regardless of the obstacle, the antenna reveals indications of movement and is partly extended. Credit: ESA
ESAs Jupiter Icy Moons Explorer (Juice) has encountered a release concern with its Radar for Icy Moons Exploration (RIME) antenna. The issue, potentially caused by a stuck pin, is being dealt with by ESAs mission control teams with different strategies, consisting of an engine burn and spacecraft rotations. Despite this, Juices other instruments are functioning correctly, and theres a two-month window to solve the issue.
Juices ice-penetrating RIME antenna has not yet been released as planned. Throughout the first week of commissioning, a problem emerged with the 16-meter-long Radar for Icy Moons Exploration (RIME) antenna, which is avoiding it from being released from its installing bracket. Juice is currently 3.5 million km (2.2 million miles) from Earth.
Work continues to release the radar and groups at ESAs objective control center in Darmstadt, Germany, in addition to partners in science and market, have great deals of ideas up their sleeves.
The Radar for Icy Moons Exploration (RIME) antenna on ESAs Jupiter Icy Moons Explorer (Juice) spacecraft has actually come across a problem preventing its implementation. ESAs Jupiter Icy Moons Explorer (Juice) has actually come across a release issue with its Radar for Icy Moons Exploration (RIME) antenna. Juices ice-penetrating RIME antenna has actually not yet been released as prepared. Juices stuck however moving RIME antenna is caught by the Juice Monitoring Camera on board the spacecraft.
