А новый стенд который для Ареса начинали строить? Что с ним? Достроили?

What's the Story Behind NASA's $349 Million Unused Test Tower? Here's What We Know
Фотографии стенда и хода его строительства на странице NASA

Спойлер

When the A-3 test stand was conceived, it was part of a grand plan. It was going to be used by NASA for testing the J-2X rocket engine, which would be used to take humans back up on the moon.
The test stand was completed in June, with construction work totaling $349 million. Expensive, yes, but that's not the real problem. What's worse than spending millions of tax-payer dollars? Spending millions of tax-payer dollars for nothing.
Apparently, America is no longer keen on going to the moon, shelving the rocket program the A-3 test stand was made for back in 2010. That was four years ago yet construction continued on the test stand. Having known that the test stand would not be used for anything, NASA mothballed the structure, closing it up and leaving it empty without having been ever used.
Now that the A-3 test stand is done, it will need to be "maintained," a task that will cost NASA around $700,000 a year. That's $700,000 annually for a test stand that will never be used.
Space travel oozed American pride so there was no one prouder about what they were doing than the construction crew hired to erect the gargantuan test stand. Imagine their surprise to find out that their work would never be utilized, just standing in the Stennis Space Center like a ghost.
"What the hell are they doing? I mean, that's a lot of people's hard-earned money. It's heartbreaking to know that, you know, you thought you'd done something good. And all you've done is go around in a damn circle, like a dog chasing his tail," said David Forshee, general foreman for pipefitters assigned to build the A-3 test stand.
Forshee should take that up with then-Sen. Kay Bailey Hutchinson (R-Tex) who was responsible for keeping the A-3 test stand's construction going. Deftly, in a meeting, Hutchinson moved that amendments be adopted to the NASA reauthorization bill. When everyone in the committee said "aye," Sen. Roger Wicker's amendment that NASA "shall complete construction and activation of the A-3 test stand with a completion goal of Sept. 30, 2013" was approved. The Senate passed the bill, followed by the House. Then President Barack Obama signed the bill into law.
In an interview this year, Hutchinson said she doesn't remember how Wicker was able to include his amendment during the meeting. When Wicker was himself asked, "Just talented legislating" was all he had to say.

Бгг.. повторится история с Аресом
Первый пуск состоится в любом случае - слишком далеко работа зашла.
А потом можно, по славной американской традиции, всё похерить

А зачем обязательно государственная ракета?

It could mean that the agency is willing to use rockets and spacecraft developed by private space corporations instead of the SLS and Orion if they will be cheaper to maintain and operate. SpaceX is already working on reusable Falcon Heavy rockets designed for deep space exploration like the SLS. Jeff Bezos' Blue Origin and United Launch Alliance have contenders of their own, as well. But if the new administration doesn't scrap the project, NASA hopes to send SLS and Orion to space once a year by 2023.

Ну что, похоже на то, что Not как обычно облажался... Предсказывал что откажутся от "частников" в пользу SLS, а оно вон как поворачивается... Впрочем подождем, это пока слова, не дела...

Скорее всего, резать будут бюджет, а не ракету.

Notional schedule of future missions, through EM-10 in 2030. One set aside for ARM crewed mission, rest simply "proving ground" cislunar.

Gerst: large co-manifest cargo capability on EM-2, on the order of 7 metric tons. Looking to see what is best use of it.

Gerst shows this chart of the proposed EM-2 mission plan. Only 8 days, lunar flyby/free return only, not DRO.

NASA's Bill Gerstenmaier: while EM-1 will go to distant retrograde lunar orbit, EM-2 (1st crewed mission) on free return lunar traj instead.

Угу,. ещё Трамп в полномочия не вступил. SLS слишком дорогая РН, с малым темпом производства. Вообще не понятно как с таким темпом производства может выглядеть марсианская экспедиция для которой нужен ну минимум пятипуск. А все эти высосанные из пальца планы строительства ЛОС?! Зачем?
В Луне интересна только лунная поверхность.
Для того чтобы в США был супертяж и даже не один, нужна политика кнута и пряника, и социалистическое соревнование частников за гос-бабло на супертяж. Только цели, сначала нужны реальные, во всяком случае интересные и потенциально (пусть в отдаленной перспективе) полезные цели. 
Допустим - межпланетный перелет, выход на орбиту, посещение спутников - исследование, поверхность - исследования, Луна, Марс, Венера (без поверхности, естественно), допустим Седна, Веста, Паллада - лет на 50 хватит. 
Потом - снизить стоимость полёта до возможности более-менее массового туризма.- до 5 млн, а желательно <1 млн. у.е. Отличная цель. 
В полезность космической солнечной энергетики я не верю, а вот какое-то специфическое производство в условиях микрогравитации возможно имеет смысл разівивать.

Пилотируемые полёты на Седну предлагаете?
