Why NASA's Road To Mars Plan Proves That It Should Return To the Moon First

MarkWhittington writes: NASASpaceFlight.com published the results of current NASA thinking concerning what needs to be launched and when to support a crewed mission to Phobos and two crewed missions to the Martian surface between 2033 and 2043. The result is a mind-numbingly complex operation involving dozens of launches to cis-lunar space and Mars using the heavy lift Space Launch System. The architecture includes a collection of habitation modules, Mars landers, propulsion units (both chemical rockets and solar electric propulsion) and other parts of a Mars ship.

    But I think it would take an awful lot of launches to get the fuel production up and running on the moon. And you'd need to design a new, hopefully reusable, moon launched vehicle/fuel depot.

    I think the real problem is how expensive the SLS will be to launch, not the number of launches. Build a truly reusable vehicle, orbit the fuel depots around Earth. Send ISRU equipment to Mars (with lots of backups) and produce the fuel for the return trip. Then the cost of launching large payloads is reduced and there is no need to build a Moon base.

    Any mars vessel is going to be dozens of big parts. Think not only ISS size, but three times that size.

    You need a massive rocket to get to mars, and a second one to get back. The return rocket actually has to get there first too. You need extra fuel tanks, a mars base which has to be big enough to grow food in. You need a rocket to go from mars ground to orbit to dock with the return rocket etc.

    Even if you were smart and combined a shuttle orbiter type vessel and just kept picking up extra boosters and fuel tanks, you still have to get those parts out there to begin with. Once built just putting the support equipment in place is a decade long job, before you launch people.

    having a Moon base would help with construction, and more importantly storage. Even better is if the moon actually has water with which we can use as fuel. as lunar orbit is cheaper to reach than earth orbit by a significant margin.

      You can't do a one launch manned trip to Mars, land and relaunch back to Earth. Isn't going to happen.

      It's going to take multiple launches with some construction in space. Might as well do the construction on the Moon which is easily reachable.

      Back in the day, one of the concepts they were considering was several trips to bring up the various parts they needed. It lost out to the discarded parts concept, where you just continued to throw away parts of the vehicle over time, finally ending up with only the capsule.

      Worked pretty good.

      With a Mars trip, it will be more likley needed to assemble parts outside of the earth's atmosphere. But certainly the Mars and earth re-entry vehicles will need real life testing, but other parts? They would be candidates for off earth assembly.

      But here's the dig. All of the tonnage will first need to reach Earth's escape velocity, head to the moon, and then after assembly, head off toward Mars at the lunar escape velocity. So first you have to accellerate to around 7 miles per second on every flight, then decelerate to orbit the moon, then after assembly, accerate to around 1.5 miles per second.

      And that's just from orbit. If you plan on landing and relauncinh from the moon, there's just all that much more fuel used. to get to escape velocity.

      Having one off-earth assembly station in orbit around earth will require one launch for each component, assembly, then one acceleration to escape velocity. Other advantages are being nearer to earth for changes or emergencies, and a whole lot less unknowns. We already have experience with off-earth in oprbit construction with the ISS.

      Couple with the needed research and construction and development needed to build a moon base, doing a Mars trip this way is probably approaching a hundred years. In earth orbit, much much less time.

But mostly the point of this is if you don't have a big enough (or efficient enough) rocket to push it all up in one launch.

By 1970, the US were again the leading technology powerhouse of the planet, with US companies being the top, not among the top, but actually being THE top, of technology development. The US industry drew from this technological advantage until long into the 1980s and in some areas until the turn of the millennium. Even without any large scale investment in that area.

    For those who have not been paying attention:

    President Obama has sabotaged any plan to get to Mars in the next few decades by the following actions:

    1. He initially killed the Constellation program, which was designed to go to Mars and which, while begun under Bush, was actually supported by both parties in both the House and Senate (a near political miracle). He initially tried to replace Constellation with nothing, but then supported commercial crew to/from low Earth Orbit (to service the ISS which will be splashed into the Pacific in 2024 or 2028). He has slow-walked, obstructed, and transferred funds away from the big Mars rocket congress mandated and now his administrator has indicated it will not be able to fly its first manned mission until 2024. This stalled the post-Columbia disaster bi-partisan support for a Mars push. It also did not help that Obama sent his Administrator Charlie Bolden to go on Al Jazeera TV and tell them NASA's main mission under Obama was to make Muslims feel good about their contributions to science (see it on YouTube) - this showed a complete lack of seriousness about manned spaceflight.

    2. Obama claimed, as he was ordering lots of shuttle-era infrastructure destroyed and employees laid off, that he was converting Kennedy Space Center into a futuristic "multi-user" launch facility where multiple rocket types from multiple vendors would be stacked in the VAB and rolled out to the two pads (39A and 39B) which would be restored to Apollo-era-style "clean pads". The old Apollo and Shuttle support structured in the VAB were ripped-out to be replaced with structured theoretically supporting a wide variety of rockets. Each vendor would use a custom MLP adapted to his rocket, would stack in one of the 4 VAB high bays, and any would be able to launch from either pad. This was all a lie. Obama made a deal with SpaceX who have trashed the 39A pad, making it unusable by anything but a SpaceX Falcon9, and constraining SLS rockets to only 39B which will choke the maximum flight rate. Musk has built a large building, complete with huge corporate logo, right in the middle of the crawler way on OUR national historic landmark which he is mutilating.

    3. Everybody knows a Mars mission will require either a handful of Large SLS-sized rockets or a LOT of smaller rocket launches. Obama has limited the manufacturing capacity of SLS to 2 per year, and the trashed 39A means all SLS launches MUST use 39B which will require refurbishing between launches as all pads do. This means there will be no way to launch enough of the large rockets rapidly enough to assemble a large Mars mission in orbit in a reasonable time. If it takes 6 SLS launches to send 3 people to Mars, just assembling that in orbit will take THREE YEARS thanks to Obama.

    4. Of course, the larger problem is that Obama has DOUBLED the national debt in only 7 years. The Nation will owe $20,000,000,000,000 by the time he leaves office and will have promised to pay-out another $200,000,000,000,000 in benefits for which it has not yet found a source of funds. We now spend 70% of the national budget on welfare and other social programs, plus hundreds of billions of dollars per year just in interest on the debt. Interest rates have been held artificially-low during the Obama years but MUST eventually rise - and when they do the interest on the debt will balloon to be more than we spend on the entire military. The CBO (the non-political institutional budget analysis service of congress) says it can see no way for the government to pay all the bills beyond the year 2030. There is simply NO WAY the taxpayers will fund a space program while social security checks are bouncing in 2030. It's over. Get used to it.

    I think its appropriate to rehash what is always brought up about space. It won't happen until companies are making money from it and I mean from something other than just performing the mission. Currently, there is a TON of money being made in commercial space with respect to communications satellites in GEOs, some MEO, and emerging LEO. There was money to be made and the commercial world stepped in. We have around a dozen satellites going up each year.

    With respect to humans in space, there hasn't been a market to drive a need for it. Mining and things along that route are too much of a risk for commercial companies to move to. A fundamental question any company asks is what the other guy is doing. Right now, the only other human space flight guy is NASA with the ISS. LEO is space but not by much so the commercial world has mainly focused on space tourism - something that they know will work since we've been doing it for decades. That's not to say that its easy by any means but the risk involved is much smaller than doing something beyond LEO.

    IMHO, the moon makes sense because NASA needs to be the one to push the risk they took to get to LEO out to the Moon. Only then will commercial space follow. Take the CRS (Commercial Resupply Service) missions, for example, which are currently flown by Orbital ATK and SpaceX. These are commercial companies who are delivering supplies to the ISS. Not to offend anyone but I will focus on Orbital ATK for my example since they represent what people think of when they think of the free market. They are a company out to make money and are responsible to shareholders. They will do what makes sense to survive. SpaceX is an oddity since it is are financially responsible to no one and is led by someone who plans to die on Mars.

    The risk to fly to ISS was acceptable enough for Orbital ATK to take. While the primary mission remains to resupply the ISS, what is less publicized, is the money being made by an emerging market for space in LEO. This includes Nanoracks, who can't stuff enough of the things on the spaceships, along with other more science based experiments. The market is growing.

    NASA has to be one to give the markets some data to calculate the risk to within some level of confidence. The problem with a mission such as Mars is that it will take a long time to reduce that risk. Take a look at how many shuttle flights make folks comfortable enough to accept risk to ISS. The same would happen with Mars but would take much longer (generations). The article makes that painfully clear.

    The moon offers what the ISS has become. Routine flights to that destination will recreate what we have today with CRS. That is the reality - again ignoring SpaceX at the moment. Once a company such as Orbital ATK thinks it makes sense to go to a Moon base for financial purposes, we'll be where we are today with respect to ISS. Then NASA can focus on pushing that further (to Mars or elsewhere) but it makes sense that they don't leave the Commercial world behind too far. If they do, we end up with more Apollo type missions - successful but not permanent achievements.

    Watching paint dry, to me, is boring. $100B is a cheap price to pay to do something different. Besides, in the future, money is just a footnote in a history book.

    Yes, once we work out how to generate infinite free energy and faster than light travel the universe will become a much more interesting place.

    We can't even get past the Van Allen radiation.

    There's several hundred satellites and unmanned missions beyond the Van Allen belts. And we had seven manned trips from Apollo (1 lunar orbit and 6 lunar landings). I don't really see the point of saying stuff that is so easy to disprove.

    I imagine OP was one of those moon landing hoax guys, as they've "proved" that it would be impossible to send a man to the moon without him dying of radiation poisoning. Or the bites of venomous space bats. Something like that.

    The problem is that if we hadn't, those fuckers would have consolidated power and brought the fight here. It's much cheaper to fight at home, if you're a bean counter. It's much better to figth in some other fuckers country if you're a dad.

    If you really believe that either Sadaam Hussein or the Taliban were capable of invading the US, you are deranged.
