The years of dial - up internet , AOL Instant Messenger , and Myspace may be over on Earth , but on Mars , the former years of the internet still live on . A Martian spacecraft has been running on software design more than 20 years ago in a proprietary surroundings based on Microsoft Windows 98 , and is long delinquent for an upgrade .
The European Space Agency ( ESA ) isupdatingitsMars Expressorbiter ’s MARSIS ( Mars Advanced Radar for Subsurface and Ioniospheric Sounding ) software , 19 eld after the spacecraft launched . The MARSIS instrument , the first radiolocation sounder to orbit another planet , help in the discovery of grounds for water on Mars in 2018 . MARSIS sends low - frequency tuner undulation towards the major planet using a huge , 131 base longsighted ( 40 meters ) feeler , as the Mars Express spacecraft orb around Mars .
The MARSIS does all of that using extremely superannuated software that has n’t been updated since the space vehicle launched in June 2003 . The software was design in an environment based on Windows 98 , which does n’t act upon with the innovative - sidereal day net unless you pass over through a sight of hoops . “ After tenner of fruitful science and having gained a proficient savvy of Mars , we wanted to advertise the instrument ’s public presentation beyond some of the limitation required back when the delegation began , ” Andrea Cicchetti , MARSIS deputy main investigator , who led the development of the upgrade , order in astatement .

The new software was design by the National Institute for Astrophysics in Italy , which operates the spacecraft . The team behind the new computer software carry out a number of upgrades that would ameliorate the instrument ’s power to transport and receive signals , as well as its on - board data processing “ to increase the amount and timber of scientific discipline information sent to Earth , ” according to ESA .
“ Previously , to study the most important features on Mars , and to take its moon Phobos at all , we rely on a complex technique that stored a lot of high-pitched - resolution data and fill up up the instrument ’s on - board memory very apace , ” Cicchetti allege . “ By cast out data point that we do n’t need , the new software allows us to swop MARSIS on for five fourth dimension as long and explore a much declamatory field with each pass . ”
The new package will be used to study region near the south magnetic pole on Mars , where signs of liquid water system on the Red Planet were previously find in lower - closure data point . With MARSIS ditching its Windows 98 era software , it will be able to see those neighborhood much quicker , using high resolution data . Figuring out whether Mars had liquid piddle is of the essence to eff whether the major planet was ever inhabitable during its early history , and if it could have possibly hosted some sort of animation .
Mars Express has been hard at employment for the past 19 year , with the spacecraft ’s mission being extended seven times so far . Although it is currently ESA ’s lowest - monetary value foreign mission , Mars Express has been delivering worthful datum on Mars , and its moon Phobos . And with the new software update , the squad behind the space vehicle is gestate greater things from this retro orbiter . “ It really is like make a marque new tool on board Mars Express almost 20 years after launch , ” Cicchetti aver .
