Solar System – Spacecraft Classification

Spacecraft Classification

To withstand the harshest of conditions, robotic spacecraft are meticulously engineered and meticulously built. They have a wide range of skills and abilities, and they do a wide range of tasks. Since the missions that these spacecraft are designed to carry out have changed over time, this bankruptcy has designated eight big orders for robotic spacecraft at random:
Spacecraft flybys
The spacecraft Orbiter
a spacecraft that travels through the atmosphere
NASA’s Lander planetary explorer.
Precisely-updated satellite
Vehicles such as the Mars Exploration Rover
Up-to-date information on spacecraft

Satellites with a focus on communications and navigation

We explain each of these eight types of education by providing a good example of it, as shown on this page, along with some other examples that are related. A minimum of each excessive instance, plus an additional link or two, should be up-to-date. An extensive list of all JPL robot spacecraft missions is available on the JPL website, including past, present, and prospective missions. Currently, human-carrying spacecraft are not being taken into consideration.

Spaceships of all shapes and sizes can be seen in the sky. Despite the large number of spacecraft, Spacecraft Classification allows us to simply distinguish between them. A flyby spacecraft, an orbiter spacecraft, an atmospheric spacecraft, a lander spacecraft, a penetrator spacecraft, a Rover spacecraft, and a communications satellite are all now in the sky.

The first phase of solar gadget exploration was conducted out by flyby spacecraft. They follow a break-out trajectory or a non-stop solar orbit, and will not be trapped into a planetary orbit. They should be able to keep track of targets they’ve missed using their devices. When the goal appears to move within the contraptions’ area of view, their optical devices should be able to pan to compensate. Downlinking and storing records aboard during periods when their antennas are not pointed at the Earth is a must. They should be able to survive for extended periods of time on an interplanetary journey. With the help of thrusters or response wheels, a flyby spacecraft can be stabilised in three axes. Alternatively, the spacecraft can be constructed to spin constantly to maintain its position.

Our high example of the flyby spacecraft category is the pair of Voyager spacecraft, which performed encounters in the Jupiter, Saturn, Uranus, and Neptune systems. Various examples of flyby spacecraft include:

Return of the Stardust Cometary sample

Mariner 2 to Venus

Mariner 4 to Mars

To Venus, Mariner Five.

Martian missions by the Mariner 6 and 7 spacecraft

Mercury to Mariner 10: Mariner 10

To Jupiter and Saturn with Pioneer 10 and 11

The Pluto-Kuiper Belt problem of New Horizons

Orbiter Spacecraft

To enter orbit around a distant planet, a spacecraft must have a powerful propellant system that can slow it down gradually at just the right moment. It must be built to handle the reality that the sun will occult the spaceship at some point, decreasing the solar panels’ ability to generate electricity and putting the vehicle in a harsh thermal model. Uplink and downlink communications with Earth will be reduced due to an increase in Earth occultations as well. In the second phase of the sun system exploration, the Orbiter spacecraft is doing a thorough examination of each of the planets, following up the initial reconnaissance. Magellan, Galileo, Mars international Surveyor, Mars Odyssey, Cassini, and Messenger are all included in the long list.

Galileo is the best-known example of an orbiter spacecraft in the United States, having entered orbit around Jupiter in 1995 to conduct a successful study of the Jovian system. The following are some illustrations of orbiter spacecraft:

Atmospheric Spacecraft

Atmospheric Spacecraft

When it comes to collecting information on the atmospheres of planets and satellites, atmospheric spacecraft are built for short-term missions. In most cases, just a small number of spacecraft subsystems are included. Propulsion subsystems and attitude and articulation manipulator devices may not be necessary for an atmospheric spacecraft, as an example. Battery-powered power transport is required, as well as a telecommunications system to monitor the system’s performance and communicate information. There are also direct measures of the environment’s composition, temperature, and pressure as well as cloud content and lightning.

Atmospheric spacecraft are frequently transported to their destination by mimicking the movement of another spacecraft. To prepare for atmospheric entry, Galileo enhanced its spin-fee in 1995 by putting it on an impact trajectory with Jupiter. To avoid crashing into Jupiter, Galileo changed course after launch and entered a Jupiter Orbit Insertion trajectory. After the aeroshell was converted into jettisoning, parachutes were deployed to extract the probe from the many tiers of warmth caused by atmospheric compression during atmospheric access. The probe was powered entirely by batteries until it came to the end of its mission, and the orbiter sent back data to Earth. In 1978, the Pioneer 13 Venus Multiprobe experiment sent four atmospheric probes into the Venusian atmosphere, returning data immediately to Earth.

Atmospheric probes suspended from a buoyant gasoline bag are known as “balloon packages,” and its purpose is to go with the flow and explore the wind. When the Soviet Vega 1 and Vega 2 spacecraft flew by Venus in 1986, they dropped balloons in the planet’s atmosphere on their way to study Comet Halley. The instrumented balloons were tracked by the DSN in order to study the winds in the Venusian atmosphere. (Venus landers were also used by the Vega missions.) Current designs for several types of atmospheric spacecraft include battery-powered instrumented planes and balloon for Mars and Titan atmosphere investigations, despite the fact that they are not currently funded.

Huygens, which was transported to Titan by the Cassini mission, is our best example of an atmospheric spacecraft. Atmosphere spaceship can take various forms, for instance

Lander Spacecraft

Lander Spacecraft

They’re made to land on the surface of a planet and last long enough to send back data to Earth via telemetry. Soviet Venera landers, JPL’s Viking landers, and NASA’s Surveyor collection of landers on Earth’s moon have all been effective examples of landers that can endure harsh environments while simultaneously doing chemical composition studies and transmitting color images. The Mars Pathfinder mission, which landed on the red planet on July 4, 1997, was intended to be the first of a series of landers that would explore the planet’s environment, both inside and out. Carl Sagan Memorial Mars Station was eventually renamed to honor the lander’s personal devices. Sojourner, Pathfinder’s second rover, was also deployed. There are plans to build a system of long-lived, actively cooled Venus landers for seismological experiments.

Our high example of the lander spacecraft magnificence is Mars Pathfinder. landing spacecraft include the likes of

Surveyors of the Moon

Penetrator Spacecraft

This type of ground penetrator was meant to pierce the floor of a comet, withstand a massive G force, and measure the homes in the ground. For re-transmission to Earth, penetrator data is often telemetered to an orbiter craft. Efforts to conduct Penetrator missions have been limited to a restricted number since January 2013. Although a cometary penetrator was originally planned for the Comet Rendezvous / Asteroid Flyby (CRAF) mission, the project was ultimately shelved due to budgetary concerns in 1992. On December 3rd, 1999, the Mars Polar Lander’s Deep area 2 penetrators, which were attached to the Deep area 2 probe, succeeded in planting Martian soil. Unfortunately, there were no records to transfer.

Penetrator Spacecraft

The Deep Impact spacecraft, which was released on January 12th, 2005, is a prime example of a penetrator spacecraft. Deep effect’s impactor module successfully smashed with the nucleus of comet 9P/Tempel, releasing a plume that was tracked by the probe. Penetrator spacecraft include, among other things:

Assignment of a comet to a deep influence

Europa has been assigned the task of selecting an ice sample.

Lunar-A is a mission to the Moon.

Robotic Vehicle (RV)

JPL is responsible for the design, construction, testing, launch, and operation of all-electric rover spacecraft used in the search for life on Mars. The Mars Pathfinder lander, which landed on Mars on July 4, 1997, carried the first Mars Rover. As a result, the Sojourner solar-powered mobile machine was renamed. A larger version of the rocker-bogie mobility gear has now been utilized on all Mars rovers to date because it was such a success.

two Mars Exploration Rovers

Rovers Spirit and Opportunity made their debut on the red planet in 2004. As of January 2013, one’s sun-powered rovers have exceeded their ninety-Martian-day high endeavor; the chance exists. This successful geology laboratory, powered by radioisotope thermoelectric turbines, landed on Mars in 2012 and was named Curiosity.

The rover craft aspires to a degree of self-sufficiency. In spite of the fact that they can be steered from Earth, the lag in radio communications between Earth and Mars means that they will have to make certain decisions on their own while they drift. The Sojourner Rover is our best example of a rover spacecraft, as shown in this picture taken from the surface of Mars. one-of-a-kind rover spacecraft include:

Observatory Spacecraft

Observatory Spacecraft

It is no longer necessary for an observatory spacecraft to travel to a specific location to do research. A solar orbit or an Earth orbit is another option, allowing it to see far-off targets without interference from Earth’s atmosphere, which would otherwise obscure or distort their appearance. From infra-purple to gamma rays, NASA’s Great Observatories program studies the universe. the Chandra X-ray Observatory (CXO, formerly known as AXAF), the Compton Gamma Ray Observatory (GRO), and the Spitzer Space Telescope (SST) make up this system (formerly known as SIRTF).

As of early 2013, the HST is still operational. In June of 2000, GRO completed its venture and transformed into de-orbited. CXO was made available to the public in July 1999 and is still in use today. It was introduced in January 2003 and is currently taking a stroll around the block Many new types of observatory spacecraft could be launched in the coming years to take advantage of the huge improvements that running in the region can provide.

The Spitzer region Infrared Telescope Facility is our best example of an observatory spacecraft. The following are a few examples of several kinds of observatory spacecraft:

Atmospheric and Nuclear Spectroscopic Array

An Infrared Survey Explorer with a large field of view

The Hubble Space Telescope (HST).

The Chandra X-Ray Observatory

Gamma-ray observatory Compton

Atmospheric Research Satellite (IRAS)

The Next-Generation Space Telescope (NGST)

The JWST Telescope was installed by James Webb.

Communications & Navigation Spacecraft

Communications & Navigation Spacecraft

Despite the abundance of Earth-orbiting communications and navigation spacecraft, JPL’s missions may necessitate their use. The Ground Communications Facility for the Deep Space Community uses Earth-orbiting communications satellites to send information between its websites in Spain, Australia, California, and JPL. Earth-orbiting worldwide positioning device navigation spacecraft are used by the Deep place network to maintain a precise time reference.

Communications and navigation spacecraft may be put on Mars, Venus, or other planets in the future to communicate with orbiters, rover/penetrator/atmospheric spacecraft, and other spacecraft operating in their vicinity. Many orbiter spacecraft are already in use to some level for this task, and they can also be used for limited communications relay. In order to improve connection with the Deep Space Network’s resident spacecraft, dedicated Mars communications orbiters may be necessary. As of early 2013, none had been funded or developed. In Chapter 18, we take a second look at this concept.

NASA’s TDRSS (Tracking and Data Relay Satellite) serves as a communications spacecraft example. The Hubble Telescope, the gap shuttle, GRO, Landsat, TOPEX, JASON, and EUVE, and the worldwide vicinity Station are all supported by the gadget. The following are some more types of spacecraft used for communication and navigation:


a global system for determining location (GPS)

An expanding number of data points on the solar system’s planets, moons, comets, and asteroids has made it more difficult for astronomers to establish ideas regarding its genesis. In ancient times, theories about the origins of the Earth and the celestial bodies that could be seen in the sky were much freer. Scientific investigation into the birth of the solar system was not possible until Isaac Newton’s equations of motion and gravity were published in 1687.
