Наконец то рекорд проекта "Джуно" перекрыт.
Много автоматов использовало пневматические бамперы.
Мало пилотируемых капсул было в разработке. Пилотируемые американские капсулы садились на воду. Советские амортизировались ДМП еще со времен Восхода. Китайцы повторили советские образцы.
Обязательства перед партнерами РФ выполнила. На российском сегменте 4 порта, работает доставка людей и грузов, двигательная установка выполняет коррекции орбиты, СОЖ работает. Остались какие-то невыполненные обязательства?

Mars may possess a stark and austere beauty, but a manned Red Planet mission will likely not be easy on the eyes.
Recently, scientists have begun realizing that spaceflight can cause serious and perhaps permanent vision problems in astronauts. NASA researchers are working hard to understand the issue, which could present a major hurdle to mounting manned missions to Mars and other faraway destinations.

One of the most hotly debated topics related to sending humans to Mars is the health effects of prolonged exposure to microgravity and how these might be mitigated.
Prolonged exposure to microgravity (a.k.a. “zero gravity”) has several serious effects on the human body:
Without the need to support the weight of the body, the musculoskeletal system atrophies and weakens. Bone and muscle mass tend to decrease at a significant rate. Bone mass can decrease at 1-1.5% per month.
Under normal gravitational forces blood pressure is highest at the feet and legs, and lowest in the head. In microgravity, however, blood pressure is distributed evenly along the body length. The sustained, higher blood pressure in the head can affect brain function and vision.
Without the need to pump blood around the body against the force of gravity, the heart does not need to work as hard and can therefore also atrophy and weaken.
The longer a person spends in microgravity the more serious these effects become, and the longer it takes to recover after they return to Earth.

Nearly everything we know about the radiation exposure on a trip to Mars we have learned in the past 200 days.
For much longer, we have known that space is a risky place to be, radiation being one of many reasons. We believed that once our explorers safely landed on the surface of Mars, the planet would provide shielding from the ravages of radiation. We didn’t how much, or how little, until very recently. Radiation and its variations impact not only the planning of human and robotic missions, but also the search for life taking place right now.
