  Archeops is a balloon-borne experiment designed to measure the temperature
fluctuations of the CMB on a large region of the sky ($\simeq 30%$) with a high
angular resolution (10 arcminutes) and a high sensitivity ($60\mu K$ per
pixel). Archeops will perform a measurement of the CMB anisotropies power
spectrum from large angular scales ($\ell\simeq 30$) to small angular scales
($\ell \simeq 800$). Archeops flew for the first time for a test flight in July
1999 from Sicily to Spain and the first scientific flight took place from
Sweden to Russia in January 2001. The data analysis is on its way and I present
here preliminary results, realistic simulations showing the expected accuracy
on the measurement of the power spectrum and perspectives for the incoming
flights (Winter 2001/2003).
