Humans on Mars in 8 years? From any other president it would be lunacy, but with Trump at the helm it just might work

Last month US President Donald Trump signed a bill into law that further focused NASA’s continuing goal of sending humans to Mars by the 2030s. Laying out in detail the steps the agency will take to reach this goal, it was welcomed by those at NASA, who have been itching to visit the Red Planet as quickly as possible.

“We’re all very much looking forward, as directed by your new NASA bill, we’re excited about the missions to Mars in the 2030s,” the brilliant Commander Peggy Whitson, who yesterday broke the US cumulative space record, told Trump in a live streamed video call from the International Space Station. “We are absolutely ready to go to Mars. It’s going to be a fantastic journey getting up there and very exciting times. All of us would be happy to go.”

But yesterday during the conversation with Whitson, Trump made comments that suggest he’s hoping to move that target forward significantly. First, he asked the Commander how quickly she thought humans would get to Mars, to which she reiterated the 2030s goal and explained some of the challenges associated with getting to Earth’s nearest planetary neighbour.

“Well we want to do it during my first term,” Trump then responded, to laughs from his daughter Ivanka, who also was in attendance, “or at worst during my second term, so we’ll have to speed that up a little bit, okay?”

This, naturally, was jumped on by the left-wing press as the latest way to lambast Trump, but is it possible that it could be achievable?

Well, if we’re talking about first term – no, unfortunately not. NASA is still in the process of building its Space Launch System, the rocket that will be capable of manned missions to Mars, and the first test flight is not due until next year. There are also a huge number of issues that remain unresolved – not least that unless a solution to the vast amounts of radiation the astronauts would be exposed to is developed, there’s a good chance they could arrive at Mars with little clue about why they were there.

Add the fact that a flight to Mars would take between 150 and 300 days depending on planetary alignment and fuel usage, and a goal of just three years and nine months to arrive is simply not achievable.

Seven years and nine months – ie at the end of Trump’s second term – however is considerably more plausible, albeit still very ambitious. But Trump is nothing if not ambitious, and if he’s prepared to provide the support to make it happen, it really could be pulled off.

Mars by 2025?

If Trump were to formally move forward the Mars goal, he’d likely be looking at right at the end of his third term, so 2025. Conversely, his NASA bill has a tentative date of 2033: eight years later, meaning he’d effectively be halving the time left before humans landed on the Red Planet.

But there’s a lot to do. Only so much can be determined in low-Earth orbit – phase one of NASA’s work toward the Red Planet – and from next year NASA plans to embark on phase two of its Journey to Mars, using cis-Lunar space to test humans’ ability to live without reliance on Earth. That would have to be sped up – meaning more missions more quickly – in order to move to the third and final phase, and ultimately a manned trip to Mars.

However, even on the longer target of 2033, the mission is going to require vast funds and international support, as Whitson explained during her video stream.

“Unfortunately spaceflight takes a lot of time and money, so getting there will require some international cooperation to get it to be a planet-wide approach in order to make it successful, just because it is a very expensive endeavour,” she said. “But it is so worthwhile doing.”

The funding, in particular, is going to be a serious challenge. Trump’s 2018 budget proposal sees NASA escaping the gouging cuts faced by many other departments, but it is set to lose 1% of its budget. However, its remit will be more tightly focused on the Mars mission, with education and Earth observation taking the damage.

But while that is relatively promising for fans of a manned Mars mission, if Trump is going to follow in John F Kennedy’s footsteps and make a short-term, big-goal space project a central morale booster, he’s going to have to follow Kennedy’s approach to funding the space agency. And that means adding far more money to NASA’s pot – potentially at least at the levels of Kennedy’s NASA, which would be equivalent to more than twice the current NASA budget.

In real terms, NASA’s current budget is slightly under half its peak during the run up to the Moon landing

For some the answer may lie in the commercial space industry, which is seeing dramatic growth, and is set to be dominated by US companies. And Trump’s NASA bill continues this support, showing there is certainly a strong business case to be had in transitioning low-Earth orbit activities to private companies. But while the commercial space industry is undoubtedly going to provide massive incomes in the future, in general it is not currently a profitable field, and so is unlikely to be a major source of financial gain for NASA within the time Trump would need.

Whatever you think of Trump, it’s clear that he’s a fan of space, and as part of the generation that watched the Moon landing live on black and white televisions, it’s no surprise. Now he’s at the helm, it seems he wants to ensure that next great moment in US space-faring is under his command. I probably would too if I were president.

But no matter how enthusiastic he is about the space agency and its plans, if he wants to make it happen, he’s going to need to put a lot more money behind NASA. Will alone will not speed up the journey to Mars, so if Trump is serious we should see a big uptick in the NASA budget next time around.

New research claims a video game can improve doctors’ ability to recognise severe trauma in patients

New research has concluded a specifically-designed video game improves doctors’ ability to recognise when patients need to be transferred to a severe trauma centre.

The research, by the University of Pittsburgh School of Medicine and published today in the BMJ, revealed the game Night Shift was better at preparing doctors to recognise patients who needed higher levels of care than reading traditional educational materials.

This was the case even though doctors who were made to play the game, in which doctors play as a fictitious, young emergency physician treating severe trauma patients, enjoyed it less than those who were asked to read relevant materials.

“Physicians must make decisions quickly and with incomplete information. Each year, 30,000 preventable deaths occur after injury, in part because patients with severe injuries who initially present to non-trauma centres are not promptly transferred to a hospital that can provide appropriate care,” said the game’s creator Deepika Mohan, MD, MPH and assistant professor in Pitt’s departments of Critical Care Medicine and Surgery.

“An hour of playing the video game recalibrated physicians’ brains to such a degree that, six months later, they were still out-performing their peers in recognising severe trauma.”

Night Shift was designed by Mohan to tap into the part of the brain that uses pattern recognition and previous experience to make snap decisions by using subconscious mental shortcuts – a process called heuristics.

Doctors in non-trauma centres typically see only about one severe trauma per 1,000 patients. As a result, their heuristic abilities can become skewed toward obvious injuries such as gunshot wounds, and miss equally severe traumas such as internal injuries from falls.

On average, 70% of severely injured patients who present to non-trauma centres are under-triaged and not transferred to trauma centres as recommended by clinical practice.

“There are many reasons beyond the doctor’s heuristics as to why a severe trauma patient wouldn’t be transferred to a trauma centre, ranging from not having an ambulance available to a lack of proper diagnostic tools,” said Mohan.

“So, it is important to emphasize that recalibrating heuristics won’t completely solve the under-triage problem and that the problem isn’t entirely due to physicians’ diagnostic skills. But it’s heartening to know we’re on track to develop a game that shows promise at improving on current educational training.”

For the study, Mohan recruited 368 physicians from across the US who did not work at hospitals specialising in severe trauma. Half were assigned to play the game and half were asked to spend at least an hour reading the educational materials.

Participants then responded to questionnaires and completed a simulation that tested how often they “under-triaged,” or failed to send severe trauma patients to hospitals with the resources necessary to handle them.

Physicians who played the game under-triaged 53% of the time, compared with 64% for those who read the educational materials.

Six months later, Mohan reassessed the physicians and found that the effect of the game persisted, with those who played the game under-triaging 57% of the time, compared to 74% for those who had read the educational materials.
