Powered Descent
Vertical takeoff, vertical landing (VTVL) is a form of takeoff and landing for rockets. Multiple VTVL craft have flown. The most widely known and commercially successful VTVL rocket is SpaceX's Falcon 9 first stage. VTVL technologies were developed substantially with small rockets after 2000, in part due to incentive prize competitions like the Lunar Lander Challenge. Successful small VTVL rockets were developed by Masten Space Systems, Armadillo Aerospace, and others. Starting in the mid-2010s, VTVL was under intense development as a technology for reusable rockets large enough to transport people. In 2013, SpaceX demonstrated vertical landing on a Falcon 9 prototype after climbing 744 meters in the air. Later, Blue Origin (New Shepard) and SpaceX (Falcon 9), both demonstrated recovery of launch vehicles after return to the launch site (RTLS) operations, with Blue Origin's New Shepard booster rocket making the first successful vertical landing on November 23, 2015, followi ...

VTOL
A vertical take-off and landing (VTOL) aircraft is one that can take off and land vertically without relying on a runway. This classification can include a variety of types of aircraft including helicopters as well as thrust-vectoring fixed-wing aircraft and other hybrid aircraft with powered rotors such as cyclogyros/cyclocopters and gyrodynes. Some VTOL aircraft can operate in other modes as well, such as CTOL (conventional take-off & landing), STOL (short take-off & landing), or STOVL (short take-off & vertical landing). Others, such as some helicopters, can only operate as VTOL, due to the aircraft lacking landing gear that can handle taxiing. VTOL is a subset of V/STOL (vertical or short take-off & landing). Some lighter-than-air aircraft also qualify as VTOL aircraft, as they can hover, takeoff and land with vertical approach/departure profiles. Electric vertical takeoff and landing aircraft, or eVTOLs, are being developed along with more autonomous flight control tech ...

Falcon 9 Flight 20
Falcon 9 flight 20 (also known as Orbcomm OG2 M2) was a Falcon 9 space launch that occurred on 22 December 2015 at 01:29:00 UTC (21 December, 8:29:00 pm local time). It was the first time that the first stage of an orbital rocket made a successful return and vertical landing. The successful landing of the first stage at Landing Zone 1, near the launch site, was the result of a five-year technology development program to develop a reusable launch system and came on a flight test that followed the primary launch mission. Following separation of the second stage, SpaceX conducted the eighth of its controlled booster descent tests of the spent first stage, the first in which the descent target location was on land, and also the first ever successful landing. Prior to this flight, SpaceX's two previous attempts at a vertical landing and booster recovery ended in failure to recover the rocket. The success of flight 20 marked a significant milestone en route to the company's goal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xombie (rocket)
Masten Space Systems was an aerospace manufacturer startup company in Mojave, California (formerly in Santa Clara, California) that was developing a line of vertical takeoff, vertical landing (VTVL) rockets, initially for uncrewed research sub-orbital spaceflights and eventually intended to support robotic orbital spaceflight launches.

Rotary Rocket
Rotary Rocket Company was an aerospace company in the late 1990s. Its founders were among the first to recognize that the end of the Cold War represented a significant shift away from the militarization of space, to a new civilian-led, commercial space industry. In 1996, Rotary Rocket Company was formed to address this emerging market. The company developed the Roton launch vehicle as a fully reusable single-stage-to-orbit (SSTO) piloted spacecraft. The design was initially conceived by Bevin McKinney, who shared it with Gary Hudson. The Roton was intended to reduce costs of launching payloads into low earth orbit by a factor of ten. Rotary attracted considerable media attention, as well as venture capital from angel investors and opened an engineering design and test center in a facility at Mojave Air and Space Port in Mojave, California. The fuselage for their vehicles was made by Scaled Composites, at the same airport, while the company developed the novel engine design a ...

Launch Vehicle
A launch vehicle or carrier rocket is a rocket designed to carry a payload (spacecraft or satellites) from the Earth's surface to outer space. Most launch vehicles operate from a launch pad, launch pads, supported by a missile launch control center, launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to large operating costs. An orbital spaceflight, orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital spaceflight, Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles are multistage rockets which use chemical propellants such as Solid-propellant rocket, solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants. Launch vehicles are cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McDonnell Douglas DC-X
The DC-X, short for Delta Clipper or Delta Clipper Experimental, was an uncrewed prototype of a reusable single-stage-to-orbit launch vehicle built by McDonnell Douglas in conjunction with the United States Department of Defense's Strategic Defense Initiative Organization (SDIO) from 1991 to 1993. Starting 1994 until 1995, testing continued through funding of the US civil space agency NASA. In 1996, the DC-X technology was completely transferred to NASA, which upgraded the design for improved performance to create the DC-XA. Background According to writer Jerry Pournelle: "DC-X was conceived in my living room and sold to National Space Council Chairman Dan Quayle by General Graham, Max Hunter and me." According to Max Hunter, however, he had tried hard to convince Lockheed Martin of the concept's value for several years before he retired. Hunter had written a paper in 1985 entitled "The Opportunity", detailing the concept of a Single-Stage-To-Orbit spacecraft built with low- ...

Zarya (spacecraft)
The Zarya spacecraft () was a secret Soviet project of the late 1980s aiming to design and build a large crewed vertical-takeoff, vertical-landing (VTVL) reusable space capsule, a much larger replacement for the Soyuz (spacecraft). The project was developed during 1985–1989 years by Energia corporation until it was shelved in 1989, "on the eve of the Soviet Union's collapse" due to lack of funding. The name of the project was later reused by the Zarya space station module which served as the first component of International Space Station in 1998. Design The Zarya spacecraft would have differed from all previous spacecraft by having an array of a dozen rocket engines for making a soft landing upon return to Earth, without using a parachute. Mission Zarya spacecraft would have brought crew and supplies to ''Mir'' or supplies only in automated mode. It would have had a normal crew of one or two and offered the possibility of carrying a maximum of eight to twelve if used as ...

Apollo Lunar Module
The Apollo Lunar Module (LM ), originally designated the Lunar Excursion Module (LEM), was the lunar lander spacecraft that was flown between lunar orbit and the Moon's surface during the United States' Apollo program. It was the first crewed spacecraft to operate exclusively in the airless vacuum of space, and remains the only crewed vehicle to land anywhere beyond Earth. Structurally and aerodynamically incapable of flight through Earth's atmosphere, the two-stage lunar module was ferried to lunar orbit attached to the Apollo command and service module (CSM), about twice its mass. Its crew of two flew the complete lunar module from lunar orbit to the Moon's surface. During takeoff, the spent descent stage was used as a launch pad for the ascent stage which then flew back to the command module, after which it was also discarded. Overseen by Grumman, the LM's development was plagued with problems that delayed its first uncrewed flight by about ten months and its first crewed ...

Philip Bono
Philip Bono (13 January 1921 – 23 May 1993) was a Douglas Aircraft Company engineer. He was a pioneer of reusable launch system, reusable vertical landing single-stage to orbit launch vehicles. As a visionary designer, he is credited with inventing the first version of a recoverable single-stage spacecraft booster, and his contributions influenced spacecraft design. Bono pursued single-stage space launch as simpler and cheaper. He realized to do this he would need to use high specific impulse liquid hydrogen/liquid oxygen rocket engines. Afterwards he proposed to make these vehicles reusable. From his ROOST design onwards Bono advocated space launch vehicles without wings, usually using rocket assisted vertical takeoff and landing (VTVL). According to his estimates, wings consisted mostly of dead weight that decreased launch payload mass. He patented a reusable plug nozzle rocket engine which had dual use as a heat shield for atmospheric reentry. His early 1960s concepts infl ...
