Hubble's pictures provide the best view yet of Vesta's complex surface, with a geology similar to that of terrestrial worlds such as Earth or Mars. NASA's Hubble Space Telescope images of the asteroid Vesta are providing astronomers with a glimpse of the oldest terrain ever seen in the solar system and a peek into a broken off section of the "mini-planet" that exposes its interior.

As entertaining as it can be, it is also disappointingly deferential to its subjects - the work of a filmmaker in thrall to characters who have welcomed him inside the bubble. Like the project itself, “Spaceship Earth” winds up caught in the gulf between rigor and showmanship. (Food shortages in the Biosphere offered a test case.) Anyone intrigued by the prospect of romance under the dome will come away disappointed: A passing mention of couples is as steamy as this greenhouse gets. The marooned eccentrics included a physician, Roy Walford, whom we’re told believed he could live to 120 and that a low-calorie diet was the secret to longevity. But if “Spaceship Earth” isn’t taken as a full-throated endorsement of the research, it is enjoyable (and maybe even a tad insufficient) as a human interest story. The movie barely pushes back on such excuses, treating the endeavor with the same swoony reverence as Owen Pallett’s overused score. When, earlier, another participant, Linda Leigh, calls what was going on in the Biosphere “more of a different way of doing science” that is not hypothesis-driven, it sounds like what she is describing is - well, not science. The Biospherian Mark Nelson dismisses that lapse, saying that the scrubber was “inconsequential” and could take out only a “limited amount” of carbon dioxide. The Biosphere had a carbon dioxide scrubber, a device capable of removing excess amounts of the gas, even though Biosphere 2 was supposed to run off natural processes. Jane Poynter, a “Biospherian” (the term given to participants), briefly left the site for medical care and carried things in when she returned. It started with too many variables, and its integrity fell apart. Indeed, whether the live-in qualified as good science was always a sticking point for critics.
