SpinLaunch's projected cost per kg of payload is approximately $1,250 - $2,500. This projection is significantly less expensive than SpaceX's current price per kg of payload on the Falcon 9 of $6,000. SpaceX's projected cost per kg on Starship, however, is less than $1,000 per kg.
Ultimately, I believe US$500 per pound or less is very achievable". [93] This $1,100/kg ($500/lb) goal stated by Musk in 2011 is 35% of the cost of the lowest-cost-per-pound LEO-capable launch system in a 2001 study: the Zenit, a medium-lift launch vehicle that could carry 14 t (31,000 lb) into LEO for US$35–50 million.

The mass-to-charge ratio (m/Q) is a physical quantity relating the mass (quantity of matter) and the electric charge of a given particle, expressed in units of kilograms per coulomb (kg/C). It is most widely used in the electrodynamics of charged particles , e.g. in electron optics and ion optics .
Falcon 9 is a partially reusable, human-rated, two-stage-to-orbit, medium-lift launch vehicle [a] designed and manufactured in the United States by SpaceX.The first Falcon 9 launch was on 4 June 2010, and the first commercial resupply mission to the International Space Station (ISS) launched on 8 October 2012.

The launch charge also imparts spin to the projectile by a series of offset holes. Once the projectile has traveled approximately 20 metres (66 ft) from the launcher, a rocket motor in its base ignites. For the PG-9 projectile, this takes it to a velocity of 700 metres per second (2,300 ft/s) before the motor burns out.
m is the molecular mass of the metal, in kg; σ is the electric conductivity of the medium at the temperature considered, in S/m. ΔV is the voltage applied across the conductor, in V; ρ is the density (mass per unit volume) of the conductor, in kg⋅m −3; e is the elementary charge, in C; f is the number of free electrons per atom

The estimated curb weight of the NGDV is 5,560 lb (2,520 kg) for the version with a conventional ICE and 6,670 lb (3,030 kg) for the battery-electric vehicle (BEV) variant. The payload of the vehicles also varies slightly, either 2,941 lb (1,334 kg) for the ICE or 2,207 lb (1,001 kg) for the BEV. [2]: Tables 3-1.2 and 3-1.3
