A walk in the clouds: green propul\u00adsion for a satellite-based technology<\/span><\/h1>\n

Satel\u00adlites provide valu\u00adable data that makes life on Earth not only easier, but also more resource-effi\u00adcient \u2013 for instance, by aiding digi\u00adtal\u00adiza\u00adtion or enabling insights into climate change. Increas\u00adingly more and increas\u00adingly smaller satel\u00adlites are being launched into space. PROPULSE\u00ae, manu\u00adfac\u00adtured by Evonik Active Oxygens, is a green alter\u00adna\u00adtive to conven\u00adtional propel\u00adlants that is kinder to humans and the environment.<\/h4>\n\n\n\n

T<\/span>he vast expanse of space and the great unknown that is still wait\u00ading to be explored arouse desires and capture the imag\u00adi\u00adna\u00adtion. \u201cBe it moon land\u00adings, UFOs or high-speed inter\u00adnet and better commu\u00adni\u00adca\u00adtion \u2013 each one of us asso\u00adciates some\u00adthing with space,\u201d says Anna Kunkel, Senior Market\u00ading Manager for Evonik Active Oxygens\u2019 aero\u00adspace business.<\/p>\n

Almost 5,000 satel\u00adlites are orbit\u00ading Earth<\/h5>\n

In market\u00ading PROPULSE\u00ae<\/a>, the busi\u00adness line is supply\u00ading highly concen\u00adtrated hydro\u00adgen perox\u00adide<\/a> (H2<\/sub>O2<\/sub>), which is used to propel space rock\u00adets and which will enable navi\u00adga\u00adtion of satel\u00adlites in future.<\/p>\n

Manned space\u00adflight in fact only accounts for a small frac\u00adtion of what lifts off into space from Earth nowa\u00addays. Satel\u00adlites account for most traf\u00adfic in space: almost 5,000 of them<\/a> are currently on active service in orbit. Most satel\u00adlites are on a low Earth orbit trajec\u00adtory. This so-called \u201cLow Earth Orbit\u201d (LEO) covers an alti\u00adtude rang\u00ading from 200 to 2,000 kilo\u00adme\u00adters. The Inter\u00adna\u00adtional Space Station (ISS), itself a satellite, orbits the Earth at an alti\u00adtude of 400 kilo\u00adme\u00adters, for exam\u00adple. A dense network of satel\u00adlites, which commu\u00adni\u00adcate with one another rela\u00adtively close to the Earth\u2019s surface, trans\u00admit signals to Earth and provide people world\u00adwide with valu\u00adable data.<\/span><\/p>\n<\/div>\n\n\n\n

Valu\u00adable data from space makes life more sustainable<\/h5>\n

It\u2019s not just about the weather fore\u00adcast, telecom\u00admu\u00adni\u00adca\u00adtions, navi\u00adga\u00adtion or broad\u00adcast\u00ading TV programs. The data collected by satel\u00adlites helps farm\u00aders gain insights into the condi\u00adtion of soil and plants. With the aid of such infor\u00adma\u00adtion, they can save water, energy and seed\u00ading mate\u00adr\u00adial, as well as deter\u00admine opti\u00admum sowing and harvest\u00ading dates. This enables farm\u00aders to make the most of their poten\u00adtial yields as well as farm more effi\u00adciently and with less impact on resources. Many other sectors of manu\u00adfac\u00adtur\u00ading and process\u00ading indus\u00adtry are increas\u00adingly oper\u00adat\u00ading in a data-based, inter\u00adlinked manner. For exam\u00adple, satellite data is what makes the auto\u00admated shar\u00ading of infor\u00adma\u00adtion by machines feasi\u00adble in the first place, thus ensur\u00ading faster commu\u00adni\u00adca\u00adtion and more effi\u00adcient processes.<\/span><\/p>\n

Satellite data on vari\u00adables such as temper\u00ada\u00adture changes, ice distri\u00adb\u00adu\u00adtion at both poles or defor\u00adesta\u00adtion processes is also play\u00ading a key role in climate research, espe\u00adcially for moni\u00adtor\u00ading and early warn\u00ading purposes. On the basis of such data, it is possi\u00adble to assess the extent of climate change and develop adap\u00adtive strategies.<\/p>\n

Satel\u00adlites are thus making life on Earth much easier and more effi\u00adcient. There is a marked trend toward minia\u00adtur\u00adiza\u00adtion, fueled by tech\u00adno\u00adlog\u00adi\u00adcal progress and the urge for increas\u00adingly faster commu\u00adni\u00adca\u00adtion. Increas\u00adingly more and increas\u00adingly smaller satel\u00adlites are being launched into space. \u201cThe market is very active. By 2030, an esti\u00admated 1700 satel\u00adlites will be launched per annum, compared to just 230 per annum during the last decade,\u201d says Kunkel. \u201cAnd the situ\u00ada\u00adtion is evolv\u00ading at light\u00adning speed. Satel\u00adlites used to be bigger than cars. Nowa\u00addays you can hold a nanosatel\u00adlite in the palm of your hand.\u201d<\/p>\n<\/div>\n\n\n\n

PROPULSE\u00ae \u201con the same trajec\u00adtory as sustain\u00adable rocket technology\u201d<\/h5>\n

Launch vehi\u00adcles carry these useful \u201ctravel compan\u00adions\u201d into space. Large rock\u00adets currently domi\u00adnate the space market. Yet, as the number of mini satel\u00adlites increases, so does demand for mini rock\u00adets. Small, versa\u00adtile rock\u00adets enable mini satel\u00adlites to be placed much more accu\u00adrately in the desired posi\u00adtions in orbit than large ones. Satel\u00adlites in LEO, i.e. in low orbit, are also easier to replace. \u201cLife\u00adcy\u00adcles are getting shorter. They are replaced after just one or two years,\u201d says Kunkel. And what happens to satel\u00adlites that are no longer required? \u201cThe decom\u00admis\u00adsioned satel\u00adlites fly in a very low orbit. The fric\u00adtion effect gener\u00adates slow decel\u00ader\u00ada\u00adtion, which makes them descend and even\u00adtu\u00adally burn up in the Earth\u2019s atmos\u00adphere,\u201d says the expert.<\/p>\n<\/div>\n\n\n\n

Launch vehi\u00adcles require propel\u00adlants. Hydro\u00adgen perox\u00adide is one of them. And a very special one at that: Evonik Active Oxygens\u2019 PROPULSE\u00ae was devel\u00adoped specif\u00adi\u00adcally for rocket propul\u00adsion systems. Unlike conven\u00adtional propel\u00adlants, the hydro\u00adgen perox\u00adide decom\u00adpo\u00adsi\u00adtion process does not gener\u00adate any substances that are harm\u00adful to humans and the natural world, only water and oxygen.<\/p>\n

The whole world is focus\u00ading on the issues of safety and the envi\u00adron\u00adment and demand for alter\u00adna\u00adtive propel\u00adlants is increas\u00ading. The market is under\u00adgo\u00ading a trans\u00adfor\u00adma\u00adtion and there is major inter\u00adest in switch\u00ading to greener propel\u00adlants, in order to replace conven\u00adtional, toxin-based systems.<\/p>\n

PROPULSE\u00ae is there\u00adfore synony\u00admous with so-called green rock\u00adetry<\/a> \u2013 envi\u00adron\u00admen\u00adtally compat\u00adi\u00adble space\u00adflight. \u201cThis propel\u00adlant enables rocket oper\u00ada\u00adtors to mini\u00admize their envi\u00adron\u00admen\u00adtal impact and to power their rock\u00adets sustain\u00adably and cost-effec\u00adtively,\u201d says Kunkel.<\/span><\/p>\n

Stor\u00adable, low-toxi\u00adc\u00adity liquid propel\u00adlants such as hydro\u00adgen perox\u00adide are also appeal\u00ading as they offer substan\u00adtial tech\u00adni\u00adcal and commer\u00adcial bene\u00adfits. \u201cThe great thing about PROPULSE\u00ae is that it does not harm the people that come into direct contact with it.\u201d That signif\u00adi\u00adcantly reduces the cost of any occu\u00adpa\u00adtional health and safety action that needs to be taken when handling the chem\u00adi\u00adcal. In conclu\u00adsion: \u201cPROPULSE\u00ae is effi\u00adcient, easy to use and glob\u00adally avail\u00adable \u2013 and it is a sustain\u00adable trail\u00adblazer, paving the way for sustain\u00adable rocket technology.\u201d<\/p>\n<\/div>\n\n\n\n
