Atmosphere of Earth sublimated into polar-mesospheric noctilucent clouds. These are the highest clouds in the atmosphere and may be visible to the naked eye if sunlight reflects off them about an hour or two after sunset or a similar length of time before sunrise. They are most readily visible when the Sun is around 4 to 16 degrees below the horizon. Lightning-induced discharges known as transient luminous events (TLEs) occasionally form in the mesosphere above tropospheric thunderclouds. The mesosphere is also the layer where most meteors burn up upon atmospheric entrance. It is too high above Earth to be accessible to jet-powered aircraft

Colin Vickery of the "Herald Sun" called it "an early contender for worst show of the year", and Amanda Meade of "The Australian" called it "a screaming, embarrassing failure". "The Age"'s Karl Quinn stated there was "more to like than dislike" about the show. A third episode went to air in a delayed timeslot of 10:40 pm, but ratings dropped further to 189,000 viewers and on 23 February, Channel Nine announced the show had been cancelled.
