Carbon negative rocket fuel could bring Mars within range
A British rocket scientist has developed a fuel made from carbon dioxide that could make a future manned-mission to Mars viable. The fuel burns aluminium powder in carbon dioxide, using the oxygen and leaving carbon as the waste product.
Ray Wilkinson teaches rocket propulsion at the University of Hertfordshire in England and he’s about to teach the space industry how to fuel future missions to Mars with a greenhouse gas.Ray Wilkinson said, So what we’re looking at is that if we can burn something with carbon dioxide then that allows us to turn the carbon dioxide back into carbon and take energy out of it in the process and that is where the carbon negative bit comes from.
This is a hybrid rocket motor – burning solid fuel with the help of gas – normally nitrous oxide. What Wilkinson has developed is a way of using CO2 instead.Ray said, It does seem too good to be true but the science is there. It works. We can burn it with aluminium powder and we can produce carbon from it, we can remove the oxygen from the carbon dioxide and turn the carbon back into carbon.
Burning carbon dioxide with aluminium powder works fine in the laboratory but the powder has to be in suspension – not so easy during a rocket launch. So, while the chemistry is not new — the technique is. The atmosphere of Mars is 95% CO2 – so a visiting space ship could refuel for the return trip.
A manned mission to Mars is generally regarded as the next big step in space exploration…a huge challenge that Ray Wilkinson says might now be one step closer to reality.

Health Care Summit Schedule
The Obama administration has raised the stakes in the health care debate, releasing a blueprint that seeks to bridge the gap between measures passed by the Senate and House of Representatives last year. If enacted, the president’s sweeping compromise plan would constitute the biggest expansion of federal health care guarantees since the enactment of Medicare and Medicaid more than four decades ago. Among other things, the White House said it would expand Medicare prescription drug coverage, increase federal subsidies to help people buy insurance and give the federal government new authority to block excessive rate hikes by health insurance companies.
President Obama is bringing together parties from all sides today in hopes of finding a middle ground and pushing through some overhaul of health care.
Watch full coverage of the White House health care summit today beginning at 10 a.m. ET
