“ESA’s Juice spacecraft antenna stuck, possible solutions and next steps”

According to ESA, a small pin may be stuck and it is only a matter of millimeters before the antenna can be fully unfolded. Several solutions would still be possible.

“The next step is to ignite Juice’s motors. This will cause the spacecraft to shake and spin a bit, hoping to warm up the mounting bracket and antenna, which are currently in the cold shadow.”
