How to Prepare a Spacecraft for Mars
Mars has long been an alluring target for space scientists since the advent of modern space exploration. Due to its close proximity with Earth, just a modest amount of rocket fuel will get a probe there.
Mariner 9, the inaugural spacecraft to orbit Mars, returned 7,329 images and other data in 1971 – this led to numerous missions later on.
Orbiter
An orbiter is a space probe which uses cameras, spectrometers and other instruments to map out an orbit around a celestial body, gathering information about its surface and atmosphere for our understanding. They help contribute to better comprehending planet earth.
Orbiters are equipped with communication systems to allow them to contact rovers and landers on Mars as well as send data back to Earth.
In addition to the flight deck, the mid-deck includes a utility area featuring a galley, toilet, sleep locations and storage lockers. Furthermore, there is an access hatch which enables astronauts wearing EMUs to depressurize before entering payload bay for EVA preparation or after returning inside orbiter; this enables astronauts to depressurize before EVA preparation or after EVA return and repressurize upon reentry inside orbiter if need be. Spacecraft crews spend months at a time, so plenty of room is required in order for comfortable performance of tasks performed effectively before embarking upon any journey to Mars or beyond!
Lander
Landers are devices designed to reach the surface of planets and survive long enough for data transmission back to Earth. Landers may either remain stationary like Viking, or carry rovers like Curiosity for exploration.
InSight’s payload is designed to gain insight into the interior of Mars, featuring an instrument called SEIS to detect marsquakes and study its rotational dynamics and structure, as well as a “Mole” penetrometer which will use a hammer to bore five metres into Martian soil for scientists to access water records of local environments.
Wind and temperature sensors on a lander will also provide valuable meteorology data, since weather patterns vary dramatically with elevation. A “Matryoshka doll” of insulating layers helps balance changing instrument temperatures as they heat or cool down – originally designed for Carl Sagan Memorial Mars Pathfinder mission in 1997 but then applied to subsequent rovers including Opportunity and Curiosity rovers.
Rover
The main aim of the Mars Exploration Rover Mission (MERM) rover is to search for signs of life on Mars and characterize its geology, using a suite of instruments including molecular analysis to look for carbon compounds and isotopes. Furthermore, its arm will collect samples to deposit in a caching tool which will ensure they return back home on subsequent missions.
This robot is powered by two lithium-ion batteries capable of producing 110 W at full power. Typically it spends most days sleeping to conserve energy; only emerging when its power and temperature levels have reached optimal conditions.
A 20 MHz 32-bit RAD6000 processor housed within a VME card cage can perform multiple functions and keep electronics from overheating. It offers configurable parameters and advanced features which can be activated through mission commands; in addition, this rover can collect, store and send images as well as perform basic drilling operations.
Space Station
The International Space Station serves both as home and a laboratory for astronauts to learn about living in space and prepare for Mars missions.
An enormous and intricate machine with 15,000 cubic feet of living space–more than three bedrooms–has been constructed as part of NASA’s Deep Space Gateway Program to test technologies astronauts may require for deep space travel such as radiation shielding and regenerative life support systems.
Scientists onboard the International Space Station are conducting studies ranging from how humans adjust to microgravity to the effects of space travel on DNA and gene expression. Additionally, they’re exploring new technologies like augmented reality tools that let ground experts guide astronauts through complex tasks remotely.
The International Space Station will help us understand how humans can survive long-duration spaceflight and conduct scientific research efficiently – knowledge which may one day pave the way to crewed missions to Mars by as early as 2030s.
