SpaceX CRS-30
SpaceX CRS-30, sometimes identified by NASA as SpX-30, was an American cargo spacecraft flight to the International Space Station (ISS), that launched on 21 March 2024. It was operated by SpaceX under a Commercial Resupply Services (CRS) contract with NASA. The spacecraft is a , serial number C209, which made its fourth flight on this mission. This mission was the first Cargo Dragon to launch from Cape Canaveral Space Launch Complex 40 since the second generation capsule was introduced on the SpaceX CRS-21 mission. In that time, a tower and access arm were added to the pad, allowing late loading of supplies into the spacecraft. Cargo Dragon SpaceX plans to reuse the Cargo Dragons up to five times. The Cargo Dragon doesn't require SuperDraco abort engines, seats, cockpit controls, or the life support system required to sustain astronauts in space. Dragon 2 improves on Dragon 1 in several ways, including lessened refurbishment time, leading to shorter periods between flig ...

Commercial Resupply Services
Commercial Resupply Services (CRS) are a series of flights awarded by NASA for the delivery of cargo and supplies to the International Space Station (ISS) on commercially operated spacecraft. The first CRS contracts were signed in 2008 and awarded $1.6 billion to SpaceX for twelve cargo Dragon and $1.9 billion to Orbital Sciences for eight Cygnus flights, covering deliveries to 2016. The Falcon 9 and Antares rockets were also developed under the CRS program to deliver cargo spacecraft to the ISS. The first operational resupply missions were flown by SpaceX in 2012 ( SpaceX CRS-1) and Orbital Sciences in 2014 ( Cygnus CRS Orb-1). A second phase of contracts (known as CRS-2) was solicited in 2014. In 2015, NASA extended CRS-1 to twenty flights for SpaceX and twelve flights for Orbital ATK. CRS-2 contracts were awarded in January 2016 to Orbital ATK Cygnus, Sierra Nevada Corporation Dream Chaser, and SpaceX Dragon 2, for cargo transport flights beginning in 2019 and expected to ...

Fluid Mechanics
Fluid mechanics is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. It has applications in a wide range of disciplines, including mechanical, aerospace, civil, chemical and biomedical engineering, geophysics, oceanography, meteorology, astrophysics, and biology. It can be divided into fluid statics, the study of fluids at rest; and fluid dynamics, the study of the effect of forces on fluid motion. It is a branch of continuum mechanics, a subject which models matter without using the information that it is made out of atoms; that is, it models matter from a ''macroscopic'' viewpoint rather than from ''microscopic''. Fluid mechanics, especially fluid dynamics, is an active field of research, typically mathematically complex. Many problems are partly or wholly unsolved and are best addressed by numerical methods, typically using computers. A modern discipline, called computational fluid dynamics (CFD), i ...

3D Mapping
In computer vision and computer graphics, 3D reconstruction is the process of capturing the shape and appearance of real objects. This process can be accomplished either by active or passive methods. If the model is allowed to change its shape in time, this is referred to as non-rigid or spatio-temporal reconstruction. Motivation and applications The research of 3D reconstruction has always been a difficult goal. By Using 3D reconstruction one can determine any object's 3D profile, as well as knowing the 3D coordinate of any point on the profile. The 3D reconstruction of objects is a generally scientific problem and core technology of a wide variety of fields, such as Computer Aided Geometric Design (CAGD), computer graphics, computer animation, computer vision, medical imaging, computational science, virtual reality, digital media, etc. For instance, the lesion information of the patients can be presented in 3D on the computer, which offers a new and accurate approach in diag ...

Sensor
A sensor is a device that produces an output signal for the purpose of sensing a physical phenomenon. In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor. Sensors are always used with other electronics. Sensors are used in everyday objects such as touch-sensitive elevator buttons ( tactile sensor) and lamps which dim or brighten by touching the base, and in innumerable applications of which most people are never aware. With advances in micromachinery and easy-to-use microcontroller platforms, the uses of sensors have expanded beyond the traditional fields of temperature, pressure and flow measurement, for example into MARG sensors. Analog sensors such as potentiometers and force-sensing resistors are still widely used. Their applications include manufacturing and machinery, airplanes and aerospace, cars, medicine, r ...

Plant Metabolism
Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. Closely related fields include plant morphology (structure of plants), plant ecology (interactions with the environment), phytochemistry (biochemistry of plants), cell biology, genetics, biophysics and molecular biology. Fundamental processes such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration, both parts of plant water relations, are studied by plant physiologists. Aims The field of plant physiology includes the study of all the internal activities of plants—those chemical and physical processes associated with life as they occur in plants. This includes study at many levels of scale of size and time. At the smallest scale are molecular interactions of photosynthe ...

External Active Thermal Control System
The International Space Station (ISS) External Active Thermal Control System (EATCS) maintains an equilibrium when the ISS environment or heat loads exceed the capabilities of the Passive Thermal Control System (PTCS). Note Elements of the PTCS are external surface materials, insulation such as Multi-Layer Insulation (MLI), or Heat Pipes. The EATCS provides heat rejection capabilities for all the U.S. pressurized modules, the Japanese Experiment Module (JEM), the Columbus Orbital Facility (COF), and the main power distribution electronics of the S0, S1 and P1 Trusses. The EATCS consists of two independent Loops (Loop A & Loop B), which both use mechanically pumped fluid state ammonia in closed-loop circuits. The EATCS is capable of rejecting up to 70 kW, and provides a substantial upgrade in heat rejection capacity from the 14 kW capability of the Early External Active Thermal Control System (EEATCS) via the Early Ammonia Servicer (EAS), which was launched on STS-10 ...

Landing Zones 1 And 2
Landing Zone 1 and Landing Zone 2, also known as LZ-1 and LZ-2 respectively, are landing facilities on Cape Canaveral Space Force Station for recovering components of SpaceX's VTVL reusable launch vehicles. LZ-1 and LZ-2 were built on land leased in February 2015, on the site of the former Cape Canaveral Launch Complex 13. SpaceX built Landing Zone 2 at the facility to have a second landing pad, allowing two Falcon Heavy boosters to land simultaneously. Site Landing Zones 1 and 2 are located at the former location of Launch Complex 13, which has been demolished and replaced by two circular landing pads in diameter and marked with a stylized ''X'' from the SpaceX company logo. Four more diameter pads were initially planned to be built to support the simultaneous recovery of additional boosters used by the Falcon Heavy, although only one extra pad has been built. Planned infrastructure additions to support operations includes improved roadways for crane movement, a rocket pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SuperDraco
SuperDraco is a hypergolic propellant rocket engine designed and built by SpaceX. It is part of the SpaceX Draco family of rocket engines. A redundant array of eight SuperDraco engines provides fault-tolerant propulsion for use as a launch escape system for the SpaceX Dragon 2, a passenger-carrying space capsule. SuperDraco rocket engines utilize a storable (non-cryogenic) hypergolic propellant which allows the engines to be fired many months after fueling and launch. They combine the functions of both a reaction control system and a main propulsive engine. Hypergolic fuels do not require an external source of ignition, providing increased reliability for the spacecraft. The engines are used on crew transport flights to low Earth orbit, and were also projected to be used for entry, descent and landing control of the now-canceled ''Red Dragon'' to Mars. SuperDracos are used on the SpaceX Dragon 2 crew-transporting space capsule and were used on the ''DragonFly'', a prototyp ...
