    Selling trips to the moon? Sending astronauts to Mars and back? These sound like 1960s-era science fiction adventures, but they're actually in the works for later this decade. Will these privately backed projects get off the ground? That's the billion-dollar question.

    The Golden Spike Company says it's in talks with one corporation and more than one space agency about sending a two-person expedition to the moon in the 2020 time frame, at a cost of $1.4 billion per mission. Meanwhile, the Inspiration Mars Foundation is getting ready to launch a man and a woman, preferably a middle-aged married couple, on a round-trip flyby past Mars in 2018.

    The two ventures are the focus of Wednesday night's installment of "Virtually Speaking Science," a talk show that airs online via BlogTalkRadio with a live audience in the Second Life virtual world. I'm your host, and my guests are Taber MacCallum, Inspiration Mars' chief technology officer; and Doug Griffith, general counsel for Golden Spike.

    The hour-long show starts at 9 p.m. ET (6 p.m. PT), but if you miss the live program, never fear: You can always download the podcast from BlogTalkRadio's archive or iTunes.

    Both Golden Spike and Inspiration Mars are getting advice and moral support from NASA, but the financial support is coming from elsewhere. The lunar venture expects to bootstrap its way to profitability by selling its services — and initially through an Indiegogo crowdfunding campaign aimed at raising $240,000 (one dollar for each mile to the moon) by late April. So far, more than $7,500 has been contributed.

    To Mars and back
    Inspiration Mars is relying on seed money from California millionaire Dennis Tito, who became the first tourist to visit the International Space Station in 2001. Tito said his effort to send a spacecraft zooming past Mars during a favorable planetary alignment in 2018 is purely philanthropic, with the goal of inspiring future generations of Americans.

    MacCallum, who took part in the Biosphere 2 experiment in 1991-1992 and went on to become a co-founder of Paragon Space Development Corp., said he's already noticed the inspirational effect.

    "I keep hearing people say, 'This is the kind of thing America used to do, and maybe now we can do it again.' It's like we touched on a sore spot, and the reaction has been ... almost too positive," MacCallum said.

    He said Tito's aim was merely to get some introductory exposure for the concept, in hopes that all the kinks can be worked out in time to make the 2018 deadline. Tito has committed to supporting the venture for its first two years, but he needs to raise the rest of the money for what's rumored to be a billion-dollar mission.

    The team hasn't yet worked out the procedure for selecting the crew, but MacCallum said more than 100 applications have already been sent in — including some candidates with jaw-dropping credentials. "There are some where you say to yourself, 'Oh, my gosh!'" MacCallum told me. "Hey, listen, it's suddenly cool to be a middle-aged couple."

    To the moon
    Unlike Inspiration Mars, Golden Spike is set up as a business, which will ultimately have to be supported by paying customers. The idea is to provide two-person trips to the moon for roughly the same cost as today's robotic missions to the moon. Golden Spike aims to do that by employing high-tech, low-cost hardware as well as a relatively low-risk mission architecture. The company plans to pre-position a lander in lunar orbit, and only then send the crew and their moon-and-back booster on a subsequent pair of launches.

    "Before it even launches, we know that the lander is working," said Griffith, who is drawing upon years of experience in space and aviation law.

    Griffith said Golden Spike will serve as the outer-space analog of, say, United Airlines, contracting with other companies for flight hardware. The company is working on design studies for launch vehicles, landers and other equipment. It's also talking with potential customers — and trying to convince the skeptics that it's really possible to put people on the moon, almost half a century after NASA did it in 1969.

    "The consensus seems to be that it's doable within the prices we're talking about," Griffith said. "All of the skepticism seems to be about whether there are space agencies or billionaires who are willing to pay the price. That is the big unknown. ... I think we'll know in fairly short order whether the skeptics are right or wrong."

    Griffith said Golden Spike's game plan calls for signing up its first customers for "right of first refusal" deals by the middle of the year, and getting its first flight contract by the end of this year.

    "Our operating premise is not that we keep sliding things back," Griffith told me. "Our operating premise for now is, it's go time."

    Are Golden Spike and Inspiration Mars ready for takeoff, or will we have to wait for NASA to send astronauts to a near-Earth asteroid in the mid-2020s, and to Mars and its moons in the mid-2030s?

  • Going to Mars in 2018: Concept is so crazy (and simple) it just might work

    The Inspiration Mars Foundation, led by millionaire space tourist Dennis Tito, has unveiled plans for a 501-day round trip to Mars. They are aiming for a 2018 launch. Tom Clarke of Channel Four Europe reports.

    By Alan Boyle, Science Editor, NBC News


    Millionaire space tourist Dennis Tito and his partners have had to tell questioners repeatedly that they're not "crazy" or "nuts" to think they can launch a man and a woman to Mars and back by 2019 — but if the Inspiration Mars Foundation's "Mission for America" succeeds, it may well be because it's just crazy enough. 

    Other private space ventures, ranging from SpaceX to the Golden Spike Company and Planetary Resources, are depending on turning a profit someday through the sale of rocket flights, or missions to the moon, or water and precious metals mined from asteroids. Tito, in contrast, freely admits the 501-day mission is a "one-shot deal" that's unencumbered by a long-range business plan. He's committed to supporting the five-year development effort for the first two years, during which time he and the rest of the team will try to raise the money and perfect the technologies for the three more expensive years to follow.

    So how much is that going to cost him? "Who knows?" Tito said.

    Tito expects to look in all the usual places for funding, including sponsorships, the sale of media rights, the sale of scientific data from the flight and private contributions. A 6-year-old boy has already sent in one of the first contributions, amounting to $10. "This is my Apollo," he was quoted as saying.

    If Tito had a dime for every time the Apollo era was invoked on Wednesday, he'd be making a good start toward a fund-raising goal that is estimated to range around $1 billion. Some questioned whether the non-stop Mars flyby would be worth it, on scientific or economic grounds. But that's missing the point: Like Tito's eight-day trip to the International Space Station in 2001, the payoff would be purely inspirational rather than scientific.

    "Inspiration Mars reminds me of Apollo 8 in 1968, going around the moon," software billionaire Charles Simonyi, who spent tens of millions of dollars buying two flights to the International Space Station, said in a Twitter update. "Inspiration is a goal for humans, science should be left to the rovers."

    In a follow-up exchange of messages, Simonyi told NBC News that he wouldn't be spending millions more to support Tito's effort. He noted that his philanthropic foundation, the Charles Simonyi Fund for Arts and Sciences, "has spent the $100M it had in 10 years, as planned."

    "But I think Inspiration will have broad-based support," he said. "Very exciting."

    NASA also voiced moral support, saying in a statement that the Inspiration Mars mission was "a testament to the audacity of America's commercial aerospace industry and the adventurous spirit of America's citizen-explorers." Inspiration Mars plans to pay NASA for access to the agency's know-how about thermal protection systems for re-entry, said Taber MacCallum, the foundation's chief technology officer and a co-founder of Paragon Space Development Corp.

    Inspiration Mars

    A graphic from Inspiration Mars shows the expected path of a spacecraft going around the far side of Mars during a 501-day round trip launched in 2018.

    Technical issues
    In addition to the craziness about the money, there's the craziness about thinking that the rocket and crew capsule will be ready to launch on Jan. 5, 2018, when the planets literally align. A launch on or around that date would result in a straightforward, no-fuss trajectory that would come within 100 miles of Mars' backside on Aug. 20, 2018, and bring the spacecraft back to Earth on May 21, 2019. The mission plan is outlined in a feasibility analysis prepared for an aerospace conference, but Tito and his co-authors acknowledge that the space vehicles cited in the paper don't yet exist.

    The paper says it'd be feasible to use the still-under-development SpaceX Falcon Heavy rocket and a modified SpaceX Dragon capsule, with a Bigelow-type inflatable module added on. But MacCallum acknowledged that Inspiration Mars was still talking with potential industry partners on what the launch configuration might be. He said choosing that configuration, as well as designing the life-support system and the thermal protection system, were high priorities on the to-do list.

    MacCallum stressed that simplicity would be the key. "This is going to be a Lewis and Clark mission to Mars," MacCallum said. "Keep it bare bones, keep it simple."

    Tito provided scant details about the five-year development timeline but said that the mission would rely upon technologies developed for flights to the space station. "It uses low-Earth-orbit architecture ... and we're just adapting it in effect to a very large Earth orbit," he said. Responding to questions about the tight time frame, Tito pointed out that Apollo 8's around-the-moon mission took place just a year after the first unmanned test launch of NASA's Saturn 5 rocket in 1967. (However, it took five years to design and develop the Saturn 5 in preparation for that first launch.)

    The trajectory for the "Mission for America" is designed such that only minor course corrections would be required along the way. There'd be no engine burn required for the return leg of the trip, and no deorbit burn. However, the spacecraft's speed at re-entry would be 32,000 mph (14.2 kilometers per second), or almost twice as fast as the space shuttle's re-entry speed. And if the trajectory went slightly off for some reason, there's a chance that the capsule could slam into Mars — or miss Earth entirely on the way back, dooming the crew to another deadly circuit. 

    Who will go?
    Jonathan Clark, a former NASA flight surgeon who has served as an adviser for several space ventures, acknowledged that "there's no question this is a risky and bold endeavor." He estimated that there was a roughly 7 percent chance that one of the two astronauts on board would experience a serious medical issue during the mission. That's the big reason why it'd be a two-person trip rather than a solo flight: so that one of the astronauts could serve as the backup for the other. That, and the fact that it'd be an awfully lonely year and a half for just one astronaut.

    Tito insists that the two-person crew should consist of a man and a woman, preferably a married couple, in order to combat the loneliness and reduce the risk of crew incompatibility. Tito joked that one of the mission's media deals might involve Dr. Phil giving "marital advice" to the couple while they're in flight.

    Like most of the spacecraft components, the crew would be American, Tito said. He described the key attribute for prospective crew members as "the Right Stuff times 10." MacCallum, meanwhile, said the astronauts would have to have "an amazing mechanical skill" in order to keep the onboard systems running smoothly. MacCallum's wife, Paragon co-founder Jane Poynter, said they'd have to be "even-keeled" to get along for a year and a half while cooped up in the outer-space equivalent of an RV. (MacCallum has said that he and Poynter would be interested in taking the Mars trip themselves.)

    Clark estimated that it would take six months to a year to work out the process for crew selection.

    Tito faced repeated questions about why he was taking on this mission — and it was clear that American pride was part of the equation. One reporter asked whether Tito merely wanted to get to Mars before the Chinese. "Beat China to Mars?" he replied. "Wouldn't I want to do that? Wouldn't I want America to do that? Wouldn't you want America to do that?"

    He also noted that if Inspiration Mars missed the launch opportunity in 2018, the next opportunity for a 501-day mission wouldn't come around again until 2031. "If we don't fly in '18, the next low-hanging fruit is in '31, and we better have our crew trained to recognize other flags," he said. "They're going to be out there."

    Update for 8:25 p.m. ET: Tito's plan has also gotten a vote of support from Apollo 11 astronaut Buzz Aldrin, who is writing a book titled "Mission to Mars: My Vision for Exploration." The Washington Post's Brian Vastag quotes Aldrin as saying, "I've talked with Dennis, and I've strongly encouraged him. The purpose is to inspire, to say we're going to do something and then we do it." It doesn't hurt that the schedule calls for the round trip to end two months before the 50th anniversary of the Apollo 11 moon landing.

    Update for 9:50 p.m. ET: Here's another vote of support from planetary scientist Alan Stern, president and CEO of the Golden Spike Company: "Very excited about Inspiration Mars and the way they and we at Golden Spike are both breaking the mold in human space exploration in this country — and around the world," Stern wrote in an email. Golden Spike is working on a plan to launch missions to the moon at a cost of $1.4 billion per mission (that's $700 million per seat for a two-person flight). The company is currently in the midst of an Indiegogo crowdfunding campaign.

  • Millionaire Dennis Tito plans to send woman and man to Mars and back

    Animations from the Inspiration Mars Foundation trace the trajectory for a 501-day round trip to Mars.

    By Alan Boyle, Science Editor, NBC News


    Millionaire space tourist Dennis Tito's plan to send two astronauts on a 501-day flight that zooms past Mars and swings back to Earth would set plenty of precedents on the final frontier — but the most intriguing precedent might have to do with the astronauts that are to be sent: one man and one woman, preferably a married couple beyond childbearing years. We're talking about sex in space, folks.

    And if that's not intriguing enough, consider this: There are already a couple of candidates for the job.

    "We'll certainly throw our hat in the ring," said Taber MacCallum, who's a member of the development team for the 2018 mission that Tito has in mind.

    MacCallum and his wife, Jane Poynter, were crew members together in Biosphere 2, the controversial two-year-long experiment in long-term environmental containment. They went on to become co-founders of Paragon Space Development Corp., a company specializing in life-support systems for spacecraft. Their expertise in life support is why they're involved in Tito's "Mission for America," which was officially unveiled on Wednesday at the National Press Club in Washington. But it just so happens that they also fit the profile for the trip: Poynter is about 50, and MacCallum will turn 49 on July 20, the anniversary of the Apollo 11 moon landing.

    The couple won't be the only candidates in the running. "When we tell people we're proposing to send a man and a woman on a mission to Mars, as a married couple, people line up. ... That chord gets struck over and over again," MacCallum said.

    Paragon

    Taber MacCallum and his wife, Jane Poynter, are part of the planning team for a mission to Mars in 2018. They're also potential candidates to take the trip.

    MacCallum explained that Tito wants the crew on humanity's first trip to Mars to be representative of humanity, and because the current concept for the trip calls for two spacefliers, that means a man and a woman. A married couple would be ideal, MacCallum said, because of the "whole issue of companionship." MacCallum didn't refer specifically to sex, but that would presumably be part of the companionship package.

    "When you're out that far, and the Earth is a tiny, blue pinpoint, you're going to need someone you can hug," Tito told Space.com. During Wednesday's briefing, Tito told reporters that he envisioned Dr. Phil giving the couple "marital advice" during the trip.

    In addition to their experience with life-support systems (and with each other), MacCallum and Poynter can draw upon their experience with life in isolation during the Biosphere 2 experiment in Arizona, which lasted from 1991 to 1993. The isolation inside a two-room spacecraft for 501 days will be even deeper. Even though the Biosphere 2 crew was separated from the outside world, "we could walk out at any time," MacCallum pointed out.

    That's not the only challenge: Even with radiation shielding in place, the round trip to Mars is likely to involve exposure levels higher than NASA's limits, MacCallum said. (That's why the astronauts should be beyond their childbearing years and willing to accept an increased risk of cancer.)

    Then there's the exposure to the health effects of long-term weightlessness, including bone loss and muscle loss. The astronauts who fly past Mars will surpass Soviet cosmonaut Valery Polyakov's 437-day record for continuous time in microgravity, set in 1994-1995 aboard the much roomier Mir space station. 

    "We're definitely pushing boundaries," MacCallum said. "It's definitely going to be hard and challenging. But we can rely on elegance and simplicity."

    When, where and how?
    The details of the mission plan have come to light just in the past few days, but MacCallum said that Tito has been mulling over the idea for years. Tito started out as an engineer at NASA's Jet Propulsion Laboratory, helping to design trajectories for the Mariner missions to Mars in the 1970s. Then he put his math genius to work in the investment world, building California-based Wilshire Associates into a multibillion-dollar powerhouse. In 2001, he spent around $20 million of his fortune for a seat on the Russian Soyuz spacecraft traveling to and from to the International Space Station.

    After his eight-day space tour, Tito got back to business. But he also started working out a trajectory that could send a spaceship directly from Earth to Mars for a fly-by within 100 miles (160 kilometers) of the Red Planet's surface, and then back to the home planet 501 days after launch. Once the spaceship was on its way, only minor course corrections would be needed. There'd be no need for undocking or redocking ... no landing ... no do-or-die engine burn for the return from Mars.

    There's one big catch, though: The trip will have to be started when the planets were aligned just right. One opportunity will come in 2016. Then there's another one in 2018. After that, the next chance won't come around until 2031.

    Planning for a launch in January 2018 looked particularly attractive, and not just because that could plausibly provide enough time to put the mission together. That's also a time frame when solar activity is expected to be at a minimum, reducing the level of radiation exposure. So Tito assembled a team from Paragon as well as NASA's Ames Research Center and other space ventures to flesh out the mission plan.

    The plan calls for launching the two astronauts in a crew capsule with a transfer rocket stage. If the launch vehicle is powerful enough — say, the size of SpaceX's Falcon Heavy — the upper stage and the crew capsule could be launched in one go. If the rocket doesn't have that much oomph, the capsule and the upper stage could be launched separately and then linked up in Earth orbit for the push onward to Mars.

    Inspiration Mars

    An artist's conception shows how the spacecraft for the Inspiration Mars Foundation's "Mission for America" might be configured — with a crew capsule, an inflatable module similar to the ones built by Bigelow Aerospace, and an attached upper stage that could provide radiation shielding. The actual design has not yet been set.

    "We only need to attach the upper stage. There's no need to get rid of it," MacCallum said. In the right configuration, that upper stage could even provide some of the required shielding from solar radiation and heating, he said.

    The crew's 600 cubic feet of living space would include a capsule for launch and re-entry, with a well-shielded sleeping quarters that could provide a safe haven if solar storms erupted. There would be a habitat module — perhaps an inflatable module like the one that Bigelow Aerospace has been working on for NASA's use. The main idea is to keep the crew compartment as simple as possible while providing all the necessary amenities for a 501-day trip. "It's a '55 Chevy," MacCallum said.

    To test the feasibility of the plan, Tito and his colleagues looked at the specifications for the Falcon Heavy as well as a modified version of SpaceX's Dragon capsule. But MacCallum emphasized that the team was not committed to using SpaceX hardware. He said the idea was getting a "great response" from a variety of aerospace companies. "If this mission is going to happen, they want 'their vehicle' to do it," McCallum said.

    How much? And why?
    MacCallum characterized the mission as "purely philanthropic," with the aim of inspiring future scientists and engineers as well as bridging the gap in NASA's plans for exploration beyond Earth orbit. NASA's current timetable calls for astronauts to go no farther than the International Space Station until 2021 at the earliest. Even though the Mars-and-back mission wouldn't make any stops, the trip could produce useful scientific data — and an adventure as grand as the Apollo moonshots of the '60s and '70s.

    "I think we really need what Apollo did for America, but we didn't realize it while we were doing Apollo," MacCallum said.

    Toward that end, Tito set up the Inspiration Mars Foundation. "He has committed to funding the first two years of this development, and he is committed to finding the rest of the money," MacCallum said. "Dennis is already getting tremendous interest in this mission from people of means."

    The foundation is also looking into media deals and sponsorships. "Farmers Insurance cut a $700 million deal for the naming rights for a stadium," MacCallum noted. "Wow ... that's a not-insubstantial part of the money that we're talking about."

    How much money are we talking about? MacCallum quoted Tito as saying "it's a fraction of what Curiosity cost," with reference to NASA's $2.5 billion robotic mission to Mars. Other reports have put the cost in the range of $1 billion or so — which is far less than the projected price tag for the crewed missions NASA plans to send to Mars in the 2030s.

    MacCallum emphasized that Tito's "Mission for America" was meant to support America's space agency, not compete with it. "This mission is only even remotely contemplatable because of all the work that NASA has done on the International Space Station," he said. And NASA is getting something in return: MacCallum said Inspiration Mars is paying NASA for access to thermal protection technologies developed by the space agency.

    Even if MacCallum and Poynter aren't picked to go on the flight, it sounds as if they'll be having the adventure of their lives over the next five years. "I feel so thrilled every day to be working with these people," MacCallum said. "It's just fabulous."
