The NASA X-43 was an experimental unmanned hypersonic aircraft with multiple planned scale variations meant to test various aspects of hypersonic flight. It was part of the X-plane series and specifically of NASA's Hyper-X program developed in the late 1990s. [1] It set several airspeed records for jet aircraft.
NASA's budget as percentage of federal total, from 1958 to 2017. NASA's budget for financial year (FY) 2020 is $22.6 billion. [1] It represents 0.48% of the $4.7 trillion the United States plans to spend in the fiscal year. [2] Since its inception the United States has spent nearly US$650 billion (in nominal dollars) on NASA.
The X-43A craft were designed to crash into the ocean without recovery. Duct geometry and performance of the X-43 are classified. The NASA Langley, Marshall, and Glenn Centers are now all heavily engaged in hypersonic propulsion studies. The Glenn Center is taking leadership on a Mach 4 turbine engine of interest to the USAF.

In 1999, NASA projected the cost of the X-38 program at US$96 million (Space Flight Advanced Projects funds) and the actual CRV program at US$1.1 billion (ISS Program funds). [21] A year later, the X-38 costs had risen to US$124.3 million, with the increased cost being paid for by ISS funds. [20]
Furthermore, if such services were unavailable by the end of 2010, NASA would have been forced to purchase orbital transportation services on foreign spacecraft such as the Russian Federal Space Agency's Soyuz and Progress spacecraft, the European Space Agency's Automated Transfer Vehicle, or the Japan Aerospace Exploration Agency's H-II ...
When space transportation becomes safe and affordable for ordinary people numerous possibilities and opportunities can be envisioned. The vision is guided by possibilities such as living and working in space, exploring new worlds, and vacationing off the Earth. In a similar context opportunities for business and pleasure are added multiples. [2]
One effort in the direction of space transportation was the Reusable Launch Vehicle (RLV) program, initiated in 1994 by NASA. [43] This led to work on the X-33 and X-34 vehicles. [43] NASA spent about US$1 billion on developing the X-33 hoping for it be in operation by 2005. [43]
