Although NASA has a bold plan for "landing the Mars" on 2030, it does not mean that the aerospace agency can be successfully reached. In fact, NASA has recently admitted that under the current cost budget, there is simply not enough money to send to Mars, and then bring them back to Earth! Of course, to revisit the moon, then it is another matter. On Wednesday, William H. Gerstenmaier said at a meeting of the American Academy of Aeronautics and Astronautics that "I could not set a date for humans to land on Mars, but there was nothing else."
"At the budget level we described (about 2% increase), there is no way to deploy the ground system on Mars. Admission, landing and landing, for us are great challenges & rdquo ;.
As for NASA's new space toy & mdash; including the space launch system (SLS) and Orion (Orion) spacecraft & mdash; want to close to the cost of Mars is very high. In addition, the agency also needs to design lander (including landing and take off again).
However, this does not mean that NASA wants to cancel the Mars mission, in order to achieve this goal, the agency in the next few years or for more money, or with the private sector to work more affordable manned Mars mission program.
Gerstenmaier also said that NASA is exploring the mission to restart the moon, including the establishment of a base on the earth satellite:
If we find water on the earth and want to make more extensive exploration on the moon, we have the ability to expand the lunar mission with the support of the Deep Space Gateway. Even if we want more attention to Mars, you can stay.
But this does not mean that the moon project will be cheaper, even if a year with a space launch system, the cost will be more than 1 billion + dollars.
