Peering down on Mars strangely lifeless but familiar surface, Mars Express has re-written our view of a world that perhaps once looked more like our own home, and where we prepare to set foot soon.
The Mars Express spacecraft, launched by the European Space Agency in 2003, has far surpassed its planned life expectancy, using considerable insights into Mars geological and atmospheric qualities, and finding evidence of water ice on and beneath the surface area. Mars Express, introduced on June 2, 2003, at 23h45 (regional time) on board a Soyuz-Fregat rocket from the Baikonur Cosmodrome in Kazakhstan. The HRSC on ESAs Mars Express got this perspective view on February 2, 2005, during orbit 1343 with a ground resolution of around 15 meters per pixel. Its MELACOM lander relay radio was repurposed to probe the Martian atmosphere with ESAs ExoMars Trace Gas Orbiter, and importantly, it has actually been a huge aid to the whole neighborhood of science objectives at Mars, playing a vital role in supporting the landings of NASAs Phoenix objective in 2008 and the Mars Science Laboratory mission, which brought the Curiosity rover in 2012.

In human years, Mars Express would now be very old, having actually survived 5 times longer than it was designed for. While it might be feeling its age, it continues to lift the cover on the Red Planet, with implications for our understanding of our own home.
Pleased Birthday, Mars Express.

Mars Express: watershed minutes
Released on June 2, 2003, from the Baikonur Cosmodrome in Kazakhstan, Mars Express started Europes very first journey to explore our crimson next-door neighbor and undoubtedly any other planet. Carrying a suite of clinical instruments, the spacecraft aimed to study Mars geology, climate, and environment, offering important insights into its history and capacity for hosting life
One of the objectives most substantial accomplishments was the effective arrival at Mars on December 25, 2003, when the spacecraft skilfully got in orbit around the world– no simple accomplishment. Recorded by Mars gravity, a window opened up for us to catch breathtaking images of the Martian surface and altering weather condition patterns, exposing diverse landscapes from towering volcanoes to ancient riverbeds and deep valleys.

High-resolution images from the German Aerospace Centers (DLR) HRSC instrument continues to offer researchers with indispensable data, enabling them to reconstruct the worlds geological history and clarified its potential for life, previous or present.
It is not simply the images that have actually formed our understanding of Mars. Mars Expresss radar instrument, MARSIS, has been critical in spotting water ice above and surprise underneath the planets surface and the OMEGA instrument, in one of MEXs earliest discoveries, discovered exposed water ice in the polar ice caps.
Thanks to Mars Express, much of the speculation has been replaced with realities. The MARSIS instrument has actually revealed that many of Mars upper layers consist of water ice, as well as plentiful water ice in polar areas– reservoirs or ice never seen before.
A lot more exciting, was the MARSIS discovery of indications of liquid water concealed beneath layers of ice in arctic areas and “similar to Lake Vostok, found some 4 km listed below the ice in Antarctica in the world”.
These findings have far-reaching ramifications. As water is a crucial ingredient for the presence of life as we know it, Mars Express has actually stimulated more interest in future objectives to the Red Planet, concentrated on checking out the possibility of past or present microbial life.

The objective with lots of more than 9 lives.
Mars Express longevity is no accident. Its long life and years of additional science are thanks to the robust design of the spacecraft and to the ingenuity and devotion of the mission operations group at ESAs mission control in Darmstadt, Germany, the science operations group at ESAC in Madrid, Spain, and the scientists and market partners across Europe who have assisted to keep the objective flying long past its planned small life time of one Martian year (687 Earth days).
Together, MEX engineers and researchers have conquered a staggering number of problems from hundreds of millions of kilometers away.
Quickly after launch, an issue with Mars Express solar array wiring caused only 60% of the anticipated power being offered. This obstacle needed the control team to develop a totally new mission concept within the 6 months it required to reach Mars, adjusted the power settings, and managing to increase it to around 70%.

On its way to Mars, the spacecraft was likewise recovered from a number of Safe Modes, and during the release of the MARSIS radar boom, the first part ended up being stuck. The group needed to create an option to warm it up and successfully release it– we feel you, Juice.
In 2011, Mars Express experienced a mass memory problem that led to the loss of its long-lasting memory storage capabilities. In reaction, groups developed a new operational concept using the spacecrafts short-term memory storage, which required finding a method to fit 3000 telecommands into a queue that might only hold 117– which they did.
As the spacecrafts batteries also aged with time, the mission control team carried out progressively intricate power-saving procedures to maximize its durability– by optimizing power consumption and usage they made Mars Express one of the most efficient vessels to leave Earth.
The Visual Monitoring Camera (VMC) went through considerable modifications and enhancements, transforming it from a mere engineering video camera to a fully functional science instrument. This rehab permitted important clinical observations and image capture during the objective. Credit: ESA.
Significantly in 2014, Mars Express needed to browse a close encounter with comet Siding Spring. Although the comet would miss Mars and its orbiter, particles in its tail would be taking a trip at a staggering 56 km/second! Engineers secured the mission from this darting dust by changing its orbit and using Mars itself as a shield, while likewise handling to collect science observations of the unique moment a comet flew by a rocky planet.
And in 2018 MEX blazed a trail in being the very first ESA spacecraft to go gyroless. Often, the most lifetime-limiting part of aging spacecraft is the gyros (brief for gyroscopes)– rapidly spinning systems that tell a spacecraft which way round its facing in space. The objectives Flight Control Team 5 years ago reprogrammed the spacecraft so that the gyros might be switched off for extended durations, relying only on star electronic cameras to determine its orientation and likely extending the usable life of the objective by 10 years.
Regardless of all of this (and more), Mars Express has lived 18 years longer than planned. It even, in an unheard move for a spacecraft currently in orbit, grew a brand-new instrument– the Mars Webcam! Its MELACOM lander relay radio was repurposed to penetrate the Martian atmosphere with ESAs ExoMars Trace Gas Orbiter, and importantly, it has actually been a substantial aid to the entire community of science missions at Mars, playing a crucial function in supporting the landings of NASAs Phoenix mission in 2008 and the Mars Science Laboratory objective, which carried the Curiosity rover in 2012.

More Mars Express.
Mars Express life has actually been extended several times, and its not surprising that. The objective will continue its exploration of the Red Planet until a minimum of 2026, as revealed simply this year in the current objective extension.
The enduring success of Mars Express also offers important lessons for upcoming missions consisting of the ExoMars rover and sample return missions, as well as more opportunities to support partners through data relay and interaction support, including NASAs Mars Sample Return project.
Orbiting millions of kilometers away from Earth, Mars Express continues exposing tricks of Mars– a world that may when have harbored life and is set to end up being a future home for mankind. This expedition is a foundation for our continued exploration of the Solar System, and a precious chance to recall at our own world, understand its possible future, and ensure it stays the swirling green and blue dot it is today.

Mars appears in the night sky different from all the other gleaming dots in the darkness. Look thoroughly and even to the naked eye it has an orangey shade, look even closer and theres a twenty-year-old spacecraft that has actually been adoringly circling it for two years. Peering down on Mars eerily lifeless but familiar surface area, Mars Express has re-written our view of a planet that possibly when looked more like our own home, and where we plan to set foot soon.
The Mars Express spacecraft, released by the European Space Agency in 2003, has far exceeded its organized life-span, offering substantial insights into Mars atmospheric and geological attributes, and discovering evidence of water ice on and beneath the surface. Regardless of technical difficulties, the objective team has kept the spacecraft functional, aiding with other objectives like NASAs Phoenix and Mars Science Laboratory objectives. The mission will continue till a minimum of 2026.
Mars Express was provided its name because it was built and introduced in record time and at a much lower cost than previous, comparable missions, but absolutely nothing else about it has actually passed fast. In every method, Mars Express has outlasted, surpassed, and undoubtedly exceeded expectations.
