Senator Bill Nelson said the White House's decision to return to the moon could slow the process down
The United States has vowed to send experts to Mars by 2030 Legislators expressed their concern on Wednesday that poor planning and resource constraints will delay these plans.
President Donald Trump has propagated the goal of sending Americans back to the moon for the first time since the Apollo missions of the 1960s and 1970s. Build a lunar gateway to test the technology and spacecraft people will carry to Mars.
At a Washington hearing, Senator Bill Nelson said the White House's decision to return to the Moon ̵
"We do not want to rob the NASA budget with the goal, and the goal is to get people to Mars," said Nelson Democrat from Florida, who is based in Cape Canaveral and Kennedy Space Center.
"Do these missions help us achieve our goal of bringing people to Mars?" (19659004) In 2009, an independent panel of experts known as the Augustinus Commission warned that NASA's resources were not in line with their high targets.
With an annual budget of around $ 18 billion, NASA would need an extra $ 3 billion a year to get to Mars, he found.
NASA officials said earlier this year that they are trying to produce a much less space program using only inflation-related budget increases.
And the National Academies of Science has calculated that if NASA's budget continues on its current path, "the scenario of arriving on Mars will be forgotten until 2030. It would take us by 2050," Nelson added.
"I do not think we'll wait that long."

In 2017, NASA's Congressional approval required that NASA request one Created a step-by-step plan to reach Mars and sent it to Congress.
We do not have this roadmap yet, it's seven months overdue, "Nelson 59004 said" What's up? Let's take a look at the program to go to Mars and see where all the other fits in. "
Chris Carberry, CEO of Explore Mars, said at the hearing, international and private partnerships could help the US make it more affordable to reach Mars.
" Our international partners want us to lead, "said he deputies. "
" But they are worried that we will change direction. You are not sure if we will stick to the direction. "
What's more, space experts have identified about a dozen technologies that" we need to start working immediately, if we hope to land people on Mars in the 2030s, "Carberry added.  These include the development of spacecraft that can survive the hard entry into Mars and land gently enough, as well as the ability to lift people off the surface and return to Earth.
"Some It's going to take awhile to to reach, said Carberry. "We have to start working on them now."
Senator Ted Cruz, a Republican who heads the Subcommittee of the Space Senate, hopes Congress's next NASA funding proposal will be a long-term vision, rather than year after year.
"This next NASA approval, the hope is that it continues and is bolder in its aspirations," he said.
Cruz then asked retired NASA astronaut Peggy Whitson, who has spent a 665-day US record in space, for her vision of what's needed in the future.
"The most important thing is constancy of purpose," she replied.
"We must have a vision that requires more than one administration, we must have a budget line that supports the goals we want to achieve."
