The slick matter is theEarth ’s soberness , which keeps today ’s standard aircraft out of space just as for certain as it keeps you and me regrettably moored to the satellite ’s surface .
According toNASA , any vehicle hop launching into orbit has to travel about seven miles per second ( 11 kps ) , or about 25,000 mph ( 40,000 kph ) . You ’re modal sub - sonic airliner , of course , does n’t fly near that tight .
Airplanes might make it into outer space if they can reach a few lofty goals.
There ’s also fuel trouble too . The shortest length between Earth and place is about 62 miles ( 100 kilometre ) straight up , which by general accord is where the planet ’s limit ends and subocular space begins .
To pass orbital cavity that agency , NASA call for some 520,000 gal of rocket propellent and two strap - on roquette relay link to loft a 100 - gross ton space bird and its lading into outer space in just under nine minutes . fly horizontal , you could envisage , would need much more conventional fuel than an aircraft — or a space shuttle — could transport .
That being said , there are way of life for aircraft - free-base vehicle to reach infinite . Aerospace interior designer Burt Rutan and his firm Scaled Composites built a subocular Eruca vesicaria sativa ship — SpaceShipOne — which they dropped from a high - EL aircraft . Once clear , SpaceShipOne pilot program place their vehicle skywards , erupt its rocket engine and reached suborbital place before gliding back to Earth .
The U.S. military ’s X-15 Eruca vesicaria sativa plane , too , reached the sharpness of space in a similar manner and at least one firm , Oklahoma’sRocketplane Global , Inc. is hop to refit aprivate jetairframe with rocket locomotive engine for tourism flights to suborbital space .
