Buzz Aldrin Pressures Obama For New Space Exploration Initiative 78

Posted by Soulskill from the one-small-tweet-for-man dept.
MarkWhittington writes: While he has initiated the social media campaign, #Apollo45, to commemorate the 45th anniversary of the first moon landing, Apollo 11 astronaut Buzz Aldrin is also using the occasion to campaign for an expansion of American space exploration. According to a Tuesday story in the Washington Post, Aldrin has expressed the wish that President Obama make some sort of announcement along those lines this July 20. The idea has a certain aspect of deja vu. Aldrin believes that the American civil space program is adrift and that some new space exploration, he prefers to Mars, would be just the thing to set it back on course. There is only one problem, however. President Obama has already made the big space exploration announcement. Aldrin knows this because he was there. President Obama flew to the Kennedy Space Center on April 15, 2010, with Aldrin accompanying as a photo op prop, and made the announcement that America would no longer be headed back to the moon, as was the plan under his predecessor George W. Bush. Instead American astronauts would visit an Earth approaching asteroid and then, decades hence, would land on Mars.

      True, but NASA needs to focus on what they do well (or at least what some would say they used to do well), innovation, problem solving, advanced research, etc. And hey need to let private companies handle the mundane stuff such as launch to LEO. We've seen how bad things can go (Constellation & SLS) when NASA tries to do it all.

    The latest election cycle showed that all the candidates trying to look like they are for debt reduction was willing to kill NASA altogether.

    This is despite that agency funding is minuscule compared to the rest of the federal government. NASA has become an easy target for politicians to beat up on, since the swing voters and the right don't see any benefit coming out of the agency.

    Thanks to this myopic thinking the US now depends on Russia to man the space station.

      No one is making the case for a strong space program. It is not enough to go to the moon is because it would be "cool" or inspiring or because we might make something that could be useful. The US did it during the cold war because it was seen as a battle to be won. Now the best case that can be made is that the sun will snuff out humanity in a few million years. There is no urgent need.

        Agreed. But that doesn't mean it doesn't make sense to embark on big projects. Rather than a "Hey, we're going to walk somewhere new" sort of thing, I'd like to see work on one of any number of space-related megaprojects - for example, a launch loop [wikipedia.org] and/or fallout-free nuclear rockets**. Something that could actually lower the cost of access to space to the point that it doesn't take a vast effort to go walk on another celestial body.

        ** - There's so many competing designs it's hard to know where to start. My personal concept I've mulled over is a variant of the nuclear lightbulb concept, but instead of the fused-silica bulb containig a gas or plasma core reactor which requires some unknown containment method, the concept calls for a dusty fission core (akin to a dusty fission fragment rocket), which can be electrostatically contained. The energy would be released in the infrared, not visible or ultraviolet (as in a conventional lightbulb concept), but that's fine - fused silica is also transparent to infrared, and moreover doesn't lose much IR transmission as like happens in higher frequency bands; the lower radiation rate of infrared would be compensated for by the huge surface area of the dust radiating it. The simultaneous huge amounts of electric output (from fission fragment deceleration in a grid) could be used in part to run a microwave beam, creating a plasma sheath in ducted atmospheric air surrounding the bulb (airbreathing mode) or injected gas surrounding it (rocket mode) to aid in IR absorption and keep as much of the heat away from the (reflective) walls as possible. A VASIMR-ish mode is possible if you use low gas injection rates and a magnetic nozzle. In space, gas injection could be terminated altogether and the core could be opened up to run in dusty fission fragment mode and get Isp figures in the lower hundreds of thousands. To make up for the problems with using the standard dusty fission fragment rocket proposal's (heavy) moderator in such a high power environment, my thoughts were to have it operate as a subcritical reactor with a spallation neutron source as the driver - after all, there's no shortage of electricity to run an accelerator if you're decelerating a good chunk of the fragments; you don't even have to deal with Carnot losses.

          Corr: That should read "doesn't lose much IR transmission as a consequence of neutron bombardment like happens in higher frequency bands" - accidentally lost that middle part. Fused silica and fused quartz (especially the latter, but also the former) blacken under neutron exposure, losing transparency; it's even done intentionally to make jewelry [google.is]. But the papers I ran into when researching the topic showed that this effect isn't very pronounced in the IR band.

    Buzz did an AMA yesterday on reddit: http://www.reddit.com/r/IAmA/c... [reddit.com]

    He elaborated a bit on why he thinks NASA should target Mars, and the short version is that NASA is spread thin with a tiny fraction of the budget it once had to venture to the moon. NASA needs a passion project on which they can fire on all cylinders and do something big. We can visit an asteroid, and few will raise an eyebrow. If we go to Mars, it'll be a landmark achievement that the world will make note of. It's a dream that can focus and revitalize the space program, whereas the asteroid visitation is simply aiming too low as the overarching goal for NASA.

      That's the problem, and why you can't get people stirred up over it; there's no good reason to go to Mars. There was a good reason to go to the Moon at the time. Now, not so much; which is why we don't go to the Moon anymore either. And that's okay, because it's really expensive to go.

      I never understood this. An asteroid visit is the first and most necessary step to asteroid mining which is arguably the only way to open up the solar system with chemical rockets for propulsion. Go out and grab a water rich asteroid, ship up a few hundred square meters of solar panels and start cracking the water into fuel. Obviously there are challenges involved, but not having to haul all the fuel for your interplanetary burns from the Earth's surface would cut the difficulty of a Mars mission signifi
