A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...
The following should delay launch: delay launch for 15 minutes if field mill instrument readings within 9.3 kilometres (5 nmi) of the launch pad exceed +/- 1,500 volts per meter, or +/- 1,000 volts per meter, delay launch for 30 minutes after lightning is observed within 10 nautical miles (19 km; 12 mi) of the launch pad or the flight path.
The Space Launch System core stage, or simply core stage, is the main stage of the American Space Launch System (SLS) rocket, built by The Boeing Company in the NASA Michoud Assembly Facility. At 65 m (212 ft) tall and 8.4 m (27.6 ft) in diameter, the core stage contains approximately 987 t (2,177,000 lb) of its liquid hydrogen and liquid ...
The Space Launch System (SLS) is an American super heavy-lift expendable launch vehicle used by NASA. As the primary launch vehicle of the Artemis Moon landing program, SLS is designed to launch the crewed Orion spacecraft on a trans-lunar trajectory. The first (and so far only) SLS launch was the uncrewed Artemis I, which took place on 16 ...
The Launch Services Program was established at Kennedy Space Center for NASA's acquisition and program management of expendable launch vehicle missions. A NASA/contractor team is in place to meet the mission of the Launch Services Program, which exists to provide leadership, expertise and cost-effective services in the commercial arena to ...
Space Launch Complex 9 (SLC-9) is a planned launch pad at Vandenberg Space Force Base in California, United States. Currently a greenfield, it is leased to Blue Origin as part of their plans to have a Western Range site for their New Glenn launch vehicle, joining Launch Complex 36 at Cape Canaveral . [ 1 ]
In 2018, the launch services sector accounted for $5.5 billion out of a total $344.5 billion "global space economy". [4]: 9 It is responsible for the ordering, conversion or construction of the carrier rocket, assembly and stacking, payload integration, and ultimately conducting the launch itself. Some of these tasks may be delegated or sub ...
As a result, launch costs are a large percentage of the cost of all space endeavors. If launch can be made cheaper, the total cost of space missions will be reduced. Due to the exponential nature of the rocket equation, providing even a small amount of the velocity to LEO by other means has the potential of greatly reducing the cost of getting ...
