Mars Sample Recovery Helicopter
The ''Mars Sample Recovery Helicopters'' are a pair of robotic unmanned helicopters being developed by the engineers of the American company AeroVironment Inc. and proposed in March 2022 as a means of delivering Martian soil samples from the sample depots made by the ''Perseverance'' rover to the location of the Sample Retrieval Lander (SRL) that will load these samples onto the Mars Ascent Vehicle (MAV), which, in accordance with the NASA-ESA Mars Sample Return program, will deliver them to low Martian orbit for future return to earth. Background of the project While Perseverance is busy collecting and caching samples on Mars, scientists and technicians at JPL are developing helicopters that will retrieve them. The plan flashed in June 2022, when MSR campaign needed a helicopter to recover sample tubes this bring the sample recovery helicopters into play. Design The Martian Sample recovery helicopters are being developed by AeroVironment, Inc. based on technology they pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA-ESA Mars Sample Return
The NASA-ESA Mars Sample Return (MSR) is a proposed Mars sample return mission to collect Martian rock and soil samples in 43 small, cylindrical, pencil-sized, titanium tubes and return them to Earth around 2033. The NASA-ESA plan, approved in September 2022, is to return samples using three missions: a sample collection mission (''Perseverance''), a sample retrieval mission (Sample Retrieval Lander + Mars Ascent Vehicle + Sample Transfer Arm + 2 '' Ingenuity''-class helicopters), and a return mission (Earth Return Orbiter). The mission hopes to resolve the question of whether Mars once harbored life. Although this NASA and ESA's proposal is still in the design stage as of December 2022, the first leg of gathering samples is currently being executed by the ''Perseverance'' rover. History In the summer of 2001, the Jet Propulsion Laboratory (JPL) requested mission concepts and proposals from industry-led teams (Boeing, Lockheed Martin, and TRW). The science requirements i ...

Power-to-weight Ratio
Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance. The inverse of power-to-weight, weight-to-power ratio (power loading) is a calculation commonly applied to aircraft, cars, and vehicles in general, to enable the comparison of one vehicle's performance to another. Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle. Power-to-weight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Missions To Mars
This is a list of the 50 spacecraft missions (including unsuccessful ones) relating to the planet Mars, such as orbiters and rovers. Missions ;Mission Type Legend: Mars landing locations There are a number of derelict orbiters around Mars whose location is not known precisely; there is a proposal to search for small moons, dust rings, and old orbiters with the Optical Navigation Camera on the ''Mars Reconnaissance Orbiter''. There should be 8 derelict Mars orbiters barring unforeseen events if they have not decayed as of 2016. One example is Mariner 9, which entered Mars orbit in 1971 and is expected to remain in orbit until approximately 2022, when the spacecraft is projected to enter the Martian atmosphere and either burn up or crash into the planet's surface. The Viking 1 orbiter is predicted not to decay until at least 2019. One orbiter that is confirmed to have undergone Mars atmospheric entry is Mars Climate Orbiter.

Individual Space Vehicles
An individual is that which exists as a distinct entity. Individuality (or self-hood) is the state or quality of being an individual; particularly (in the case of humans) of being a person unique from other people and possessing one's own needs or goals, rights and responsibilities. The concept of an individual features in diverse fields, including biology, law, and philosophy. Etymology From the 15th century and earlier (and also today within the fields of statistics and metaphysics) ''individual'' meant " indivisible", typically describing any numerically singular thing, but sometimes meaning "a person". From the 17th century on, ''individual'' has indicated separateness, as in individualism. Law Although individuality and individualism are commonly considered to mature with age/time and experience/wealth, a sane adult human being is usually considered by the state as an "individual person" in law, even if the person denies individual culpability ("I followed instruct ...

Extraterrestrial Aircraft
Extraterrestrial refers to any object or being beyond ( extra-) the planet Earth (terrestrial). It is derived from the Latin words ''extra'' ("outside", "outwards") and ''terrestris'' ("earthly", "of or relating to the Earth"). It may be abbreviated as "E.T." Extraterrestrial may also refer to: General topics * Extraterrestrial life, life that occurs outside of Earth and that probably did not originate from Earth ** Extraterrestrial intelligence, hypothetical intelligent extraterrestrial life ** Extraterrestrials in fiction ** List of alleged extraterrestrial beings Media and entertainment * ''Extraterrestrial'' (TV documentary), a program on the National Geographic Channel * "Extraterrestrial" (song), a 2018 song by Tynan and Kompany * "E.T."

Electric Helicopters
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of ...

Coaxial Rotor Helicopters
In geometry, coaxial means that several three-dimensional linear or planar forms share a common axis. The two-dimensional analog is '' concentric''. Common examples: A coaxial cable is a three-dimensional linear structure. It has a wire conductor in the centre (D), a circumferential outer conductor (B), and an insulating medium called the dielectric (C) separating these two conductors. The outer conductor is usually sheathed in a protective PVC outer jacket (A). All these have a common axis. The dimension and material of the conductors and insulation determine the cable's characteristic impedance and attenuation at various frequencies. Coaxial rotors are a three-dimensional planar structure: a pair of helicopter rotors (wings) mounted one above the other on concentric shafts, with the same axis of rotation (but turning in opposite directions). In loudspeaker design, coaxial speakers A coaxial loudspeaker is a loudspeaker system in which the individual driver units radiate ...

Aircraft With Counter-rotating Propellers
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...

ExoMars
ExoMars (Exobiology on Mars) is an astrobiology programme of the European Space Agency (ESA). The goals of ExoMars are to search for signs of past life on Mars, investigate how the Martian water and geochemical environment varies, investigate atmospheric trace gases and their sources and by doing so demonstrate the technologies for a future Mars sample-return mission. The first part of the programme is a mission launched in 2016 that placed the Trace Gas Orbiter into Mars orbit and released the ''Schiaparelli'' EDM lander. The orbiter is operational but the lander crashed on the planet's surface. The second part of the programme was planned to launch in July 2020, when the ''Kazachok'' lander would have delivered the ''Rosalind Franklin'' rover on the surface, supporting a science mission that was expected to last into 2022 or beyond. On 12 March 2020, it was announced that the second mission was being delayed to 2022 as a result of problems with the parachutes, which could ...
