Also, the idea of using less fuel and having a wider space capacity than most other vehicles is also a very good feature to the vehicles. But can the manufacturers pull it off? It is likely, but will it ever actually happen? These vehicles may appear sooner than we think, we'll just have to see if they become a success or just another idea that didn't meet its expectations. Only time will tell.I strongly disbelieve that the face on mars was created by aliens. I do not think that there is alien existence out there. This claim was made 20 years ago when we saw pictures of the faces. I think that it is just an natural landfrom. Evidence say that NASA would rather hide, say conspiracy theorists.
