In 1959–1961 Great Britain Atomic Energy Authority produced 125 g of 99.9% pure protactinium at a cost of $ 500 000, giving the cost of 4 000 000 USD ...
Following the successful maiden flight of the SpaceX Falcon Heavy in February 2018, and with SpaceX advertising a US$90 million list price for transporting up to 63,800 kg (140,700 lb) to low-Earth orbit, U.S. President Donald Trump said: "If the government did it, the same thing would have cost probably 40 or 50 times that amount of money. I ...
This equates to a price of US$2,350 per kg to LEO and US$5,620 per kg to GTO. In 2022, the published price for a reusable launch was $97 million. [97] In 2022 NASA contracted with SpaceX to launch the Nancy Grace Roman Space Telescope on a Falcon Heavy for approximately $255 million, including launch service and other mission related costs.

Falcon 9 was described as capable of launching approximately 9,500 kilograms (20,900 lb) to low Earth orbit and was projected to be priced at US$27 million per flight with a 3.7 m (12 ft) payload fairing and US$35 million with a 5.2 m (17 ft) fairing.
Its cargo capacity will be between 100 and 150 tonnes (220,000 and 330,000 lb), is estimated to have an R&D cost of $10 billion, [17] and production cost of about $200-million for Starship crew, $130-million for Starship tanker and $230-million for Super Heavy. The system has a less than $140/kg price tag which is possibly as low as $47/kg.
The long or imperial hundredweight of 8 stone or 112 pounds (50.80 kg) is defined in the British imperial system. [2] Under both conventions, there are 20 hundredweight in a ton, producing a "short ton" of 2,000 pounds (907.2 kg) and a "long ton" of 2,240 pounds (1,016 kg).
In 2010, the incremental cost per flight of the Space Shuttle was $409 million, or $14,186 per kilogram ($6,435 per pound) to low Earth orbit (LEO). In contrast, the comparable Proton launch vehicle cost was $141 million, or $6,721 per kilogram ($3,049 per pound) to LEO and the Soyuz 2.1 was $55 million, or $6,665 per kilogram ($3,023 per pound ...
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
