Stephen Hawking called for a massive investment in establishing colonies on the Moon and Mars in a lecture in honour of NASA's 50th anniversary. He argued that the world should devote about 10 times as much as NASA's current budget - or 0.25% of the world's financial resources - to space.
The renowned University of Cambridge physicist has previously spoken in favour of colonising space as an insurance policy against the possibility of humanity being wiped out by catastrophes like nuclear war and climate change. He argues that humanity should eventually expand to other solar systems.
But in a speech in Washington, DC, US, delivered in honour of NASA's 50th anniversary in 2008, Hawking focused on near-term possibilities, backing the space agency's goals of returning astronauts to the Moon by 2020 and sending humans to Mars soon after that. The Moon is a good place to start because it is "close by and relatively easy to reach", Hawking said. "The Moon could be a base for travel to the rest of the solar system," he added. Mars would be "the obvious next target", with its abundant supplies of frozen water, and the tantalising possibility that life may have been present there in the past......
The Augustine Commission testified before the Senate and the House of Representatives last week and were greeted with both praise and criticism by some of the legislators. Ironically, the commission was not criticized for reaching the conclusion that NASA would require a $3 billion increase in its annual budget since the legislators already knew that since our civilian space program has been underfunded for years-- if not decades. But they were rather critical about was the rather nebulous elevations of the alternatives to the Ares 1/Ares V architecture to return the US to the Moon-- especially since the commission appeared to conclude that all of the alternatives were almost equally as expensive as the Ares 1/Ares V architecture.
My own criticism of the Augustine Commission preliminary report was their odd treatment of NASA's Sidemount-heavy lift vehicle (SD-HLV) concept and the DIRECT concept for returning America to the Moon. For some reason, the Augustine Commission lumped them both together as so called shuttle derived concepts even though they are two significantly different concepts as far as complexity, development timelines, and cost. The SD-HLV only requires 8 new system starts for its development while DIRECT requires 18 and the Ares 1/ Ares V requires 35 new vehicle structural development starts. Secondly, they extended shuttle flights for 5 years onto the cost the shuttle derived concepts. There's nothing wrong with that since it would eliminate the gap between the old shuttle and the new manned space launch system. But no such financial burden was added to the Ares 1/ Ares V which would have inflated the cost of the Ares programs even more. Then in their budget analysis of the shuttle derived concepts, they required NASA to pay currently nonexistent commercial space companies to transport NASA astronauts into orbit even though both the Sidemount and DIRECT concepts are capable of transporting an Orion spacecraft to LEO just as the Ares 1 is capable of doing. Why?
The Orion vehicle is currently being funded at about $1.4 billion a year, a budget that's supposed to be increased to approximately $2 billion on average during the course of its development over the next 5 or 6 years starting in 2011. The Ares 1 is currently receiving over a billion dollars in annual funding with a budget that is set to increase up to another billion on average during the course of its development. Program integration and operations is supposed to add an additional billion on average to the cost of the Ares 1/Orion development starting in 2011. That's about a $2.6 billion dollar increase in the annual NASA budget with no funding for the development of the Ares V or the Altair lunar landing vehicles until the Ares1 and Orion vehicles are completed in 2015 or 2017. So that would mean no Moon landings until after 2020.
The current shuttle program cost about $3 billion annually. So a $3 billion dollar increase might could fund the shuttle until the Orion/Ares 1 vehicle is ready. Unfortunately, the Orion/Ares 1 would still be underfunded by about $2.6 billion. So only by canceling the shuttle program and raising the NASA budget by $2.6 billion could we fund the Orion/Ares 1. But if the space shuttle is decommissioned after 2010, this could leave NASA without a manned space vehicle for up to 5 to 7 years.
But NASA has argued that the SD-HLV could be developed for just $6.9 billion dollars over 5 to 6 years. An EDS (Earth Departure Stage) would be required to transport payloads beyond LEO at an estimated cost of less than $2.5 billion. NASA estimates the cost of developing the Altair lunar landing vehicle to be less than $4.2 billion. So in total, the cost of developing the SD-HLV plus EDS and Altair vehicles should be less than $13.6 billion. Over a 6 year vehicle development period, that would be less than $2.3 billion per year. So if the NASA's annual budget was increased by $3 billion and the Ares 1 program was canceled, there would be at least $4 billion dollars in extra funds. $600 million a year of this on average would go to the Orion program to raise its total budget close to $2 billion annually. $2.3 billion a year would go for the development of the SD-HLV, EDS, and Altair. That would leave over $1 billion a year of increased funding for program integration and operations. If the DOD (Department of Defense) has some interest in a heavy lift vehicle for launching larger satellites into polar orbit and maybe in having their own manned launch vehicle, maybe Obama can get even more funds for Orion and SD-HLV development from the military.
The main advantage of the SD-HLV over the Ares 1/Ares V architecture is that the heavy lift vehicle would be developed immediately and would be utilized for both the manned Orion and unmanned Altair launches. Additionally, there should be enough money to fully fund the development of the Altair lunar lander starting in 2010 instead of waiting until 2015 to 2017 to begin developing a lunar lander as would be the case with the Ares 1/Ares V scenario.
But what if these NASA estimates are significantly underestimated during the course of the vehicle development? Well approximately $5 billion a year in total funds would be annually committed to the development of the Orion, Altair, SD-HLV and EDS and associated infrastructure. Since all of these vehicles would be simultaneously under development and if one or more vehicles weren't ready by 2015 or 2016 then an additional $5 billion dollars would be available every year afterwords until all the vehicles are ready. That's up to $20 billion dollars in additional development funds if the vehicles are delayed until 2020 (the date when NASA is supposed to return to the Moon). So developing all of the vehicles simultaneously has clear timeline and budgetary advantages.
So in my opinion, President Obama and new NASA administrator, Bolden, need to:
1. increase the annual NASA budget by $3 billion 2. cancel the Ares 1 program 3. choose NASA's SD-HLV program to launch the Orion and Altair vehicles and 4. begin fully funding the development of the Altair lunar landing vehicle as soon 2010
After the Orion, Altair, SD-HLV and new EDS vehicles are finally developed (perhaps as early as 2016!), the current shuttle can finally be retired and its $3 billion a year budget transferred to Orion and Altair HLV operations. But what will NASA do with the extra $5 billion a year in extra funds? Hopefully some of these extra funds will to used to build a continuously growing settlement on the Moon. But the rest should be utilized to develop the next generation of space vehicles designed for sending humans and habitat structures to Mars to begin the settlement of the Martian surface and for the exploitation of the natural resources of the moons of Mars.
SAN FRANCISCO (Reuters) - A fast-growing Silicon Valley start-up firm is aiming to put its methanol-based fuel cells in electric vehicles and plug-in hybrid cars. Oorja Protonics, which sells its fuel cells to Nissan Motor Co (7201.T), is working to have a product that can be used as a range-extender in pure electric or plug-in hybrid vehicles, Chief Executive Sanjiv Malhotra said in an interview on Friday. "We would have something in 18 to 24 months," Malhotra said, adding that the company is working "very aggressively" on such a range-extending fuel cell. Small and large automakers, including Toyota Motor Co (7203.T), Nissan and Ford Motor Co (F.N), are racing to launch electric vehicle vehicles and plug-in hybrid versions in the United States.

glennwsmith said... Very nice, Marcel. This is one of the most beautifully put together, forward-looking, and yet also understated videos which I've yet seen from a major space agency -- and it just goes to show that there's a lot of good material out there if you know where to find it.
