The E and B Experiment (EBEX) will measure the cosmic microwave background radiation of a part of the sky during two sub-orbital (high-altitude) balloon flights. It is an experiment to make large, high-fidelity images of the CMB polarization anisotropies. By using a telescope which flies at over 42,000 metres high, it is possible to reduce the atmospheric absorption of microwaves to a minimum. This allows massive cost reduction compared to a satellite probe, though only a small part of the sky can be scanned and for shorter duration than a typical satellite mission such as WMAP.

  • The E and B Experiment (EBEX) will measure the cosmic microwave background radiation of a part of the sky during two sub-orbital (high-altitude) balloon flights. It is an experiment to make large, high-fidelity images of the CMB polarization anisotropies. By using a telescope which flies at over 42,000 metres high, it is possible to reduce the atmospheric absorption of microwaves to a minimum. This allows massive cost reduction compared to a satellite probe, though only a small part of the sky can be scanned and for shorter duration than a typical satellite mission such as WMAP. The first flight was an engineering flight over North America in 2009. For the science flight, EBEX was launched on 29 December 2012, near McMurdo Station in Antarctica. It circled around the South Pole using the polar vortex winds before landing on 24 January 2013 about 400 miles from McMurdo. (en)

Il primo volo è nel 2008 sopra il Nord America per eseguire dei test. Il volo successivo sarà nel 2009 e il pallone sarà lanciato dalla Stazione McMurdo nell'Antartico. Userà un vortice polare per volare attorno al Polo Sud, ritornando dopo due settimane. (it)
