The Orbital Sciences X-34 was intended to be a low-cost testbed for demonstrating "key technologies" that could be integrated into the Reusable Launch Vehicle program. It was intended to be an autonomous pilotless craft powered by a " Fastrac " liquid-propellant rocket engine, capable of reaching Mach 8 and performing 25 test flights per year.
SIMBAD. data. Vela X-1 is a pulsing, eclipsing high-mass X-ray binary (HMXB) system, associated with the Uhuru source 4U 0900-40 and the supergiant star HD 77581. The X-ray emission of the neutron star is caused by the capture and accretion of matter from the stellar wind of the supergiant companion. Vela X-1 is the prototypical detached HMXB.
Rockwell X-30. The Rockwell X-30 was an advanced technology demonstrator project for the National Aero-Space Plane ( NASP ), part of a United States project to create a single-stage-to-orbit (SSTO) spacecraft and passenger spaceliner. [ 1] Started in 1986, it was cancelled in the early 1990s before a prototype was completed, although much ...
Hercules X-1. Hercules X-1 (Her X-1), also known as 4U1656+35, is a moderately strong X-ray binary source first studied by the Uhuru satellite . It is composed of a neutron star accreting matter from a normal star (HZ Her) probably due to Roche lobe overflow.

[2] The Ryan X-13 Vertijet was 23 ft 5 in (7.14 m) long. It was just large enough to accommodate the single-place cockpit with a tilting seat and the 10,000 lbf (44 kN) thrust Rolls-Royce Avon turbojet. The high-mounted delta wing of the aircraft had a wingspan of only 21 ft (6.4 m) and was capped with flat endplates. The nose of the aircraft ...
In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial.According to the theorem, it is possible to expand the polynomial (x + y) n into a sum involving terms of the form ax b y c, where the exponents b and c are nonnegative integers with b + c = n, and the coefficient a of each term is a specific positive integer depending ...
Aurora X-65 CRANE. The Aurora X-65 CRANE is an experimental aircraft that is currently under development. In charge are the Defense Advanced Research Projects Agency (DARPA) and the Boeing subsidiary Aurora Flight Sciences. [ 1][ 2]
