    Freezing WISE's Hydrogen

    A scaffolding structure built around NASA's Wide-field Infrared Survey Explorer, or WISE, allows engineers to freeze its hydrogen coolant. The WISE infrared instrument is kept extremely cold by a bottle-like tank filled with frozen hydrogen, called the cryostat. The cryostat can be seen at the top of the spacecraft.
