US Space Agency plans to land on Mars in 2033
On the day of the NASA 2020 fiscal year budget request hearing held by the US House of Representatives Science, Space and Technology Committee, Bridenstin said that the United States plans to land astronauts on the moon ahead of 2024, with the goal of landing in 2033. Mars.
Bridenstin also explained that astronauts must live on Mars for at least two years because the Earth and Mars are on the same side of the Sun every 26 months, opening the launch window to and from Mars. Only when Mars and the Earth are on the same side of the Sun can the Mars probe be fired and Mars can travel. Therefore, 2031 and 2033 are the best time for manned to land on Mars.
The distance between Mars and the Earth is far away. Any space mission to and from Mars will take at least two years. It will take six months to reach Mars alone and three days to reach the Moon.
Last week, US Vice President Burns proposed to return American astronauts to the moon within five years, four years ahead of NASA's original plan.
At the hearing, some lawmakers questioned whether NASA could complete the mission of landing on the moon and Mars. Rep. Kendra Horne said in his opening remarks that Congress’ analysis of the Deep Space Exploration Project concluded that it was “impossible” to implement manned landings on Mars in the 1930s according to existing channels.
However, many experts and legislators are concerned that NASA may not be able to complete its mission before this date, given that the development of the space launch system (SLS), a new generation of heavy-duty launch vehicle that Boeing is building, is seriously lagging behind.
Bridenstin said that the above-mentioned moon landing and Mars mission is achievable, and he will submit an updated version of the 2020 fiscal year budget application by April 15. In the current version, NASA’s total budget is $21 billion, more than half of which will be used for space exploration.
Bridenstin emphasized the importance of returning to the moon for the US space exploration program, pointing out that the moon is the best testing ground for learning to survive in another world, and can verify relevant capabilities and technologies.
He also said that hundreds of millions of tons of water ice are expected on the moon to solve the problem of drinking water and to produce liquid oxygen and liquid hydrogen, which can be developed into rocket fuel for deep space travel in the future.
In 2017, US President Trump signed a bill that first asked NASA to study the feasibility of sending people to Mars in 2033. However, the Moon and Mars mission schedule announced by NASA last September still uses the vague representation of Mars in the 1930s.
In 2033, it is still difficult to achieve manned landing on Mars. For example, in the future when manned landing on Mars, the astronauts, landing capsules and materials equipment are heavier, and the parachute is difficult to effectively decelerate. In addition to space cranes, more advanced rocket reversal and autonomous control techniques are needed. In order to achieve an effective smooth deceleration.
In addition, because there is no global magnetic field, the space radiation on Mars is much stronger than the International Space Station and the Moon Base over the Earth. The physical damage and health risks to astronauts are much higher, and scientists need to develop better. Radiation protection technology.
In NASA's huge deep space mission, landing Mars is the highlight of manned space flight in this century. With the discovery of liquid water on Mars, this process will inevitably accelerate. So far, NASA has launched a number of orbiters, stationary landers and rover vehicles to Mars with total assets of $10 billion.
In this latest NASA image, all the plans related to the Mars mission are listed, from the Hubble telescope in the near-Earth orbit, to the space station with the ability to transfer ground fire orbit, and to many vehicles landing on the surface of Mars. The Mars Rover outlines the magnificent blueprint and strong deep-sky technical strength of NASA in the first half of this century.
