Celebrating NASA Langley's HL-20 legacy

A spacecraft of the future could have its roots in a "space taxi" concept called the HL-20, developed at NASA's Langley Research Center in Hampton, Va. Sierra Nevada, the company designing the Dream Chaser as part of NASA's Commercial Crew Development program, thanked the engineers who came up with the HL-20 and studied it 20 years ago - before the project was canceled.

the HL-20 was one of the biggest and most expensive NASA failures, that costed over $5 billion without ever fly once in space and deleted since too expensive, seriously flawed and very dangerous for the astronauts - it wasn't designed to be launched atop an Atlas V nor to land on a runway like a Shuttle (since not even has the space for the landing gears) also, the internal space of the cabin for the astronauts is less than that of a coffin

@gaetanomarano Thanks for the lively discussion about the HL-20 design developed here at NASA Langley. Our engineers have added up the investment in HL-20 research - it totaled closer to $50 million.

I want to know what that new manufacturing technique is, looks like lasers might be involved

@TheNoob978 Нет, Кентукки Бурбон, который я бы с радостью поделиться с вами. кока колы смертельно опасен!

[TheNoob978]

@DDDDanDDDD Слишком много кока колы сэр.
