The '''M-V''' rocket, also called '''M-5''' or '''Mu-5''', was a Japanese [[solid-fuel rocket]] designed to launch [[Science|scientific]] [[satellite]]s. It was a member of the [[Mu (rocket family)|Mu family]] of [[rocket]]s. The [[Institute of Space and Astronautical Science]] (ISAS) began developing the M-V in 1990 at a cost of 15 billion [[Japanese yen|yen]]. It has three stages and is {{cvt|30.7|m}} high, {{cvt|2.5|m}} in [[diameter]], and weighs about {{cvt|140000|kg}}. It was capable of launching a satellite weighing {{cvt|1800|kg}} into an [[orbit]] as high as {{cvt|250|km}}.

The first M-V rocket launched the [[HALCA]] [[radio astronomy]] satellite in 1997, and the second the [[Nozomi (spacecraft)|Nozomi Mars explorer]] in July 1998. The third rocket attempted to launch the [[ASTRO-E|Astro-E]] [[X-ray]] satellite on 10 February 2000 but failed. ISAS recovered from this setback and launched [[Hayabusa]] to [[25143 Itokawa]] in 2003. The following M-V launch was the scientific [[Suzaku (satellite)|Astro-E2]] satellite, a replacement for Astro-E, which took place on 10 July 2005. The final launch was that of the [[Hinode (satellite)|Hinode]] (SOLAR-B) spacecraft, along with the [[SSSat]] [[Miniaturized satellite|microsat]] and a [[nanosatellite]], [[HIT-SAT]], on 22 September 2006.
