Short Definition:

Sounding rocket is a small, unmanned rocket that is meant to take measurements and perform scientific experiments on suborbital flights.


Detailed Definition:

A sounding rocket is a type of rocket that is used to carry scientific instruments to high altitudes for the purpose of collecting data. These rockets are typically smaller and less powerful than other types of rockets, and are launched vertically from a launchpad. The main advantage of sounding rockets is that they can reach altitudes of up to several hundred kilometers, allowing researchers to study the upper atmosphere and the effects of space on various materials and phenomena. Sounding rockets are often used for experiments in fields such as atmospheric science, astrophysics, and meteorology.


Etymology:

Sounding rockets take their name from the nautical term “to sound,” which means to take measurements. The term doesn't come from any latin or greek words.


Sample Sentence(s):

Next week, several sounding rockets will be launched from this site.

Short Definition:
Space debris are man-made objects which are moving uncontrollably and quickly above the Earth at different altitudes. Space debris can cause significant damage to the orbiting satellites, space crafts, telescopes and space stations.

Detailed Definition:
Space debris are useless man-made objects in space. Examples might be everything from tiny flecks of paint released by thermal stress to the parts of a destroyed satellite or a dead satellite. The amount of space junk is gradually rising as the space activity is growing. To mitigate the negative impact of the debris on the working elements, space waste is divided into smaller parts. It is then either burnt in the atmosphere or sent to the graveyard orbit (especially larger objects like satellites that will no longer work). Space debris collides with each other generating more space waste. This increases the likelihood of further collisions and yields in a higher density of debris in Low Earth Orbit (LEO). This is called the Kessler syndrome.

Etymology: 
space -> spatium from Latin - meaning: space
debris -> débriser from French - meaning: break down

Sample Sentence(s):
"The problem of managingspace debrisis both an international challenge and an opportunity to preserve the space environment for future space exploration missions."

Short Definition:

A space rendezvous is a series of orbital maneuvers focused on bringing together two orbiting spacecrafts. In most cases, a space rendezvous occurs between a space station and a spaceship trying to dock to it. Rendezvous requires a precise match of the orbital velocities and position vectors of spacecrafts, allowing them to remain at a constant distance during final maneuvers or docking.

Detailed Definition:

A space rendezvous is an approach in space to a very close distance (e.g. within visual contact) between spacecrafts or between a spacecraft and a celestial object at zero or very low relative speed. The space rendezvous requires carrying out complex orbital maneuvers, which must be completed in a minimum time without excessive consumption of the propellant. Rendezvous may or may not be followed by docking or berthing, procedures which bring the spacecraft into physical contact and usually create a link between them. NASA's first attempt at rendezvous was made on June 3, 1965, when astronaut Jim McDivitt tried to maneuver his Gemini 4 spacecraft to meet the Titan II launch vehicle's upper stage. Rendezvous was first successfully accomplished by NASA on December 15, 1965, and then lead to success of Apollo's program and moon landing.

Etymology:

Space - From Middle English space, from Anglo-Norman space, variant of espace, espas et al., and spaze, variant of espace, from Latin spatium(“to stretch, to pull”).
Rendezvous - Borrowed from French rendez-vous (“appointment”)

Sample Sentence(s):

The first space rendezvous was in 1965 during Gemini program
The Shuttle Program saw more than 50 space rendezvous and docking missions

Source: https://www.colorado.edu/faculty/kantha/sites/default/files/attached-files/sandoval_space_tethers.pdf proposed catch and release cycle of a spinning space tether

Short Definition:

Space tethers are long cables attached to a counterweight. It has many applications in space such as propulsion and momentum exchange etc. This idea could help lowering the amount of money needed to transport payload into low earth orbit by hooking onto specialized spacecrafts in the future and either increasing the speed for space travel or decrease it to prepare for landing.

Detailed Definition:

Despite recent achievements in making spacecrafts fully reusable, space travel and space infrastructure continues to be quite expensive and only reserved for a few institutions and companies. The aim is to commercialize space, but to achieve that goal we still need to vastly decrease the amount of money to get payload into low earth orbit. Skyhooks, a special type of space tethers, could help lowering the cost of transportation into space. The idea is to attach cable hundreds or thousands of kilometres to a counterweight and the weight spins in a circle. The tether will be lowered to be 80-150 kilometres above the earth, where it can hook onto spacecrafts and let them go at the best point to maximize speed adjustment. This idea could make reusable rockets much lighter and cheaper by lowering the amount of rocket fuel needed.

This idea acts as a “orbital battery”, where decreasing the spacecrafts speed will increase the amount of energy in the tether and increasing the spacecrafts speed will decrease the amount of energy in the tether.

Etymology:

Space from Latinspatium

Tether from proto-Germanic teudrą(“rope;cord;shaft”)

Sample Sentence(s):

Space tethers could revolutionize the space industry by lowering the money needed to get payload into low earth orbit.

Source: https://planetfacts.org/space-weathering/


Short Definition:

Space weathering is a general term used for different surface processes which happen to objects and celestial bodies in the harsh environment of outer space.


Detailed Definition:

Bodies in the outer space, which do not have atmospheres, are exposed to a number of devastating weathering processes, such as collisions of galactic or solar cosmic rays, the irradiation, implantation and spluttering from solar wind particles; the bombardment by different sizes of meteorites and micrometeorites. These phenomena are encompassed in the blanket term space weathering. The toll that space weathering takes on both the physical and optical properties of the surfaces of many celestial bodies is an important issue, as remotely sensed data needs to be processed appropriately.


Etymology:

"space" - Old French espace, Latin spatium - room, area, distance, stretch of time

"weather" - Old English weder, Old Saxon wedar, Old Norse veðr, German wetar - wind, weather

"we-" - Proto-Germanic wedra - to blow


Sample Sentence(s):

"Space weathering has to be accounted for during the design of space equipment."

Spacecraft Propulsion

(Modifié le: vendredi 28 avril 2023, 18:09)



Short Definition:

Spacecraft Propulsion is a method utilised to accelerate a spacecraft and artificial satellites. Different methods exist for this purpose, with each method having its advantages and drawbacks. Most spacecrafts nowadays are propelled by what is called a rocket engine, which propels the space probe by heating the reaction mass and allowing it to eject out from the rear of the vehicle.


Detailed Definition:

A spacecraft propulsion system has the purpose of changing the velocity (acceleration) of a spacecraft and artificial satellites. It is utilised to both leave earth and for orbit insertion. 

To launch a spacecraft from earth, the propulsion method must overcome a higher gravitational pull to provide a positive net acceleration. The difficulty of achieving this change is directly proportional to the size of the vehicle, which is why spacecraft performance is generally discussed in amount of change in momentum per unit of propellant consumed, known as “specific impulse”. The higher the specific impulse, the better the efficiency. 

Once launched, satellites and spacecrafts may need to be moved between orbits, thus requiring propulsion. When a satellite has exhausted its ability to adjust its orbit, its useful life is over. The methods areas are divided into four groups: (1.) chemical propulsion (reaction and rocket engines), (2.) electric propulsion (ion, electrothermal and electromagnetic thrusters), (3.) advanced propulsion technologies and (4) supporting technologies. 


Etymology:

  • Spacecraft: From Latin spatium/ "room” + from Nentish creft/ "power, physical strength"
  • Propulsion: From Latin Pro (pro)/ “before” or “forward” + pellere (pulsion)/”to drive”


Sample sentence(s):

  • Light travels approximately thirty thousand times faster than any current spacecraft propulsion technology.
  • Nuclear pulse propulsion is a form of spacecraft propulsion that would use nuclear explosives to provide impulse to a spacecraft.
