Nasa should aim to reach an important milestone on the way to Mars during Donald Trump’s presidency, astronaut Buzz Aldrin told a conference on Tuesday.Nasa should aim to reach an important milestone on the way to Mars during Donald Trump’s presidency, astronaut Buzz Aldrin told a conference on Tuesday.
Trump spoke of being “ready to unlock the mysteries of space” in his inaugural address and last month signed a Nasa funding bill containing the most comprehensive language yet in support of Mars exploration, setting a target of 2033 for a manned mission.Trump spoke of being “ready to unlock the mysteries of space” in his inaugural address and last month signed a Nasa funding bill containing the most comprehensive language yet in support of Mars exploration, setting a target of 2033 for a manned mission.
Aldrin, who recently met the vice-president, Mike Pence, at the White House, declared at the Humans to Mars Summit in Washington: “I think we can all say with confidence that we are closer to Mars today than we have ever been.”Aldrin, who recently met the vice-president, Mike Pence, at the White House, declared at the Humans to Mars Summit in Washington: “I think we can all say with confidence that we are closer to Mars today than we have ever been.”
The second man to walk on the moon laid out his longstanding vision of “cycler” spacecraft that, by 2039 or earlier, could carry astronauts on the three-month trip to Mars every two years. This commute, based on gravity-assisted trajectories and with refuelling done in Earth orbit, would be more cost-efficient than launching rockets from Earth every time, he argued.The second man to walk on the moon laid out his longstanding vision of “cycler” spacecraft that, by 2039 or earlier, could carry astronauts on the three-month trip to Mars every two years.

Evidently aware of political imperatives, Aldrin suggested that one of the cyclers could be designed and tested “before the first term of the president is out”.Evidently aware of political imperatives, Aldrin suggested that one of the cyclers could be designed and tested “before the first term of the president is out”.
He told delegates at George Washington University: “I think we can send a very early version to an asteroid. They don’t get back until after the election of 2020, but at least there is an achievement of sorts that can be demonstrated.”He told delegates at George Washington University: “I think we can send a very early version to an asteroid.

The 87-year-old added: “A fly-by of Venus can be done before 2024.”The 87-year-old added: “A fly-by of Venus can be done before 2024.”
Eventually, the cyclers could send people to Mars to build a permanent settlement. “We will be achieving continued occupation on Mars with international crews and this will require a presidential commitment,” said Aldrin. “I believe this nation within two decades will lead international crews to Mars to occupy; not to visit and come back and leave it empty, but to occupy before coming back.”Eventually, the cyclers could send people to Mars to build a permanent settlement. “We will be achieving continued occupation on Mars with international crews and this will require a presidential commitment,” said Aldrin. “I believe this nation within two decades will lead international crews to Mars to occupy; not to visit and come back and leave it empty, but to occupy before coming back.”
Although grand ambitions of reaching Mars first may seem to chime with Trump’s brand of nationalism and conjure images of the stars and stripes bring planted on the red planet, Aldrin and other experts agree it must involve international cooperation.

A US-led coalition would include Europe, Russia, India, Japan and China, as well as emerging space nations the United Arab Emirates, South Korea and Saudi Arabia, Aldrin added. “We can afford to go to Mars but we must have fiscal discipline. We must focus our limited resources on only those things that are really necessary to get to Mars. In my view, we are currently spending over $6bn on programmes we do not need to get to Mars. We need reusability, every element of the system.”A US-led coalition would include Europe, Russia, India, Japan and China, as well as emerging space nations the United Arab Emirates, South Korea and Saudi Arabia, Aldrin added. “We can afford to go to Mars but we must have fiscal discipline.

Aldrin began and ended his speech with the phrases “No flags or footprints this time” and “Get your ass to Mars!”. But his plan would require a massive concentration of money to build technologies and vehicles that do not yet exist.

Nasa is currently building its most powerful ever rocket, the Space Launch System, due for test flight in 2019. The agency is aiming for a 2033 launch of a crewed mission to orbit but not land on Mars. Similarly, the Apollo missions of half a century ago circled the moon before Apollo 11 allowed Aldrin and Neil Armstrong to walk on the lunar surface.Nasa is currently building its most powerful ever rocket, the Space Launch System, due for test flight in 2019.

Aware of how John F Kennedy’s presidency is still associated with his vision of putting a man on the moon by the end of the 1960s, Trump may be alive to the political symbolism of pushing back frontiers in space. “He’s much more proactive,” said Jeff Bingham, a space industry veteran and retired US Senate staffer. “His comments are more positive than the last administration.”Aware of how John F Kennedy’s presidency is still associated with his vision of putting a man on the moon by the end of the 1960s, Trump may be alive to the political symbolism of pushing back frontiers in space. “He’s much more proactive,” said Jeff Bingham, a space industry veteran and retired US Senate staffer. “His comments are more positive than the last administration.”
Last month, during a video call with an astronaut aboard the International Space Station, Trump raised the issue of sending humans to Mars and said: “Well, we want to try and do it during my first term or, at worst, during my second term, so we’ll have to speed that up a little bit, OK?”Last month, during a video call with an astronaut aboard the International Space Station, Trump raised the issue of sending humans to Mars and said: “Well, we want to try and do it during my first term or, at worst, during my second term, so we’ll have to speed that up a little bit, OK?”
Pascal Lee, chairman of the Mars Institute and director of the Nasa Haughton-Mars Project, said: “The rumour I hear is that the president is wanting to do something that’s going to be exciting in space, and the filter seems to have been: can it be done in his first term or second term? None of this that we’re talking about here, Mars, is really doable in that short of a time frame, although going into Mars orbit is potentially something that could be pulled off before the end of a second term.Pascal Lee, chairman of the Mars Institute and director of the Nasa Haughton-Mars Project, said: “The rumour I hear is that the president is wanting to do something that’s going to be exciting in space, and the filter seems to have been: can it be done in his first term or second term?

“But at the same there’s no new administrator named yet. In that sense, we’re still in limbo, if not chaos. So where there’s chaos, there’s opportunity. This is why I think there’s a sense of optimism here because we’re now overtly talking about going to Mars, but at the same time there’s no clear commitment to going.”“But at the same there’s no new administrator named yet.

In last month’s bill, Trump and Congress retained most of Nasa’s funding, at about $19.5bn, although it slashed $200m for climate science, education programmes and an asteroid mission that it was hoped would pave the way to Mars.In last month’s bill, Trump and Congress retained most of Nasa’s funding, at about $19.5bn, although it slashed $200m for climate science, education programmes and an asteroid mission that it was hoped would pave the way to Mars.
The mood at the annual Humans to Mars Summit was upbeat. Chris Carberry, chief executive and co-founder of Explore Mars, a nonprofit organisation promoting the cause, welcomed Trump’s positive words and said: “We’re not going to have an Apollo-like moment, or Kennedy-like moment, but I don’t think we want to. That proved not to be sustainable – after we beat the Soviet Union to the moon we had no reason to continue. There are many reasons why we should explore and that’s what we’re trying to highlight.”The mood at the annual Humans to Mars Summit was upbeat.
