The Low-Density Supersonic Decelerator, otherwise known as the LDSD for short, was specially designed by NASA and the Jet Propulsion Laboratory. This is a saucer that was capable of making its way 180,000 feet into the air, before it performed a landing test amid similar conditions, all onto a giant-sized cargo vehicle which would be somewhat identical to what it will go through should it actually make it all the way to Mars. In fact, the LDSD has been touted to be the first major step in the right direction when it comes to the development of new technology where Mars landings are concerned, and who knows, other planets too, might eventually be part of the plan.
Who knows? This program might have been in operation a whole lot earlier, which then gives rise to all of the previous UFO sightings of yore.
