Rising on a tongue of flame and easing to a gentle splashdown in the Pacific Ocean nearly 4-1/2 hours later, the National Aeronautics and Space Administrations newest spaceship for human exploration made its debut earlier this month in a virtually flawless initial test flight.
Dubbed Orion, the craft has been hailed as NASAs first step toward putting humans on Mars by the 2030s. Indeed, its purpose is to reinvigorate the agencys human spaceflight program in the post-shuttle era.
But look deeper at Orions potential path to Mars, and the assumptions surrounding it, and the way ahead appears to be littered with question marks.
What will Orion do before then? Will it make enough flights to justify the program? Are NASA budgets big enough to develop the technologies needed for interim missions, let alone realistically fund a trip to Mars? In a time of fiscal austerity, will subsequent presidents and Congresses even want to make that commitment?
Since the last American set boots on the moon in 1972, politicians and NASA officials have struggled with a stubborn question: What now? The money needed to send humans to intriguing places beyond low-Earth orbit is, well, astronomical. The fall of the Soviet Union made it harder politically to justify such big budgets for human spaceflight.
Orion and its goal of a journey to Mars give NASA a fresh start. And the agency is already applying lessons learned from the recent past, looping in other countries to help pick up the tab for the spacecraft.
But the question remains: Can NASA execute a human space-exploration program on tight budgets? With Mars rovers and probes sent to the outer solar system, NASA has worked wonders with its unmanned missions. In many ways, Orion and the journey to Mars represent a test of whether the agency can do the same with its manned-exploration program.
On the plus side, Americas astronaut corps appears to be excited again.
I think youd be hard-pressed to find an astronaut past, present, or future who wouldnt love to fly in Orion, said Rex Walheim, a space shuttle mission specialist and an astronaut liaison to the team building the craft, following the Dec. 5 test flight. This is the true exploration that we live for.
But NASAs current plans for human exploration of space could span six presidential elections and a dozen sessions of Congress. How solid or consistent will Washingtons willingness to send astronauts on deep-space exploration missions be?

Can NASA's Orion program reinvigorate human spaceflight? (+video)
Venus exploration has been deemed off-limits due to its inhospitable climate -- but NASA believes Cloud City may be the answer.
Artistic concept of the permanent city. NASA Langley Research Center
A number of agencies, including, of course, NASA, are focusing solar system exploration efforts on Mars. At first glance, though, Mars doesn't really seem like the best candidate. Venus is much closer -- at a distance that ranges between 38 million kilometres and 261 million kilometres, compared to Mars' 56 million to 401 million kilometres, it's Earth's closest neighbour.
It's also comparable in size to Earth -- a radius of 6,052km to Earth's 6,371 -- and has similar density and chemical composition.
But everything else about it makes it almost utterly unvisitable. While probes have been sent to the planet's surface, they lasted, at most, just two hours before surface conditions on Venus destroyed them. These conditions include an atmospheric pressure up to 92 times greater than Earth's; a mean temperature of 462 degrees Celsius (863 degrees Fahrenheit); extreme volcanic activity; an extremely dense atmosphere consisting mostly of carbon dioxide, with a small amount of nitrogen; and a cloud layer made up of sulphuric acid.
In short, Venus? Not a top holiday destination, really.
NASA thinks it might have a solution that will allow sending humans up to check it out, though: Cloud City.
The High Altitude Venus Operational Concept -- HAVOC -- is a conceptual spacecraft designed by a team at the Systems Analysis and Concepts Directorate at NASA Langley Research Center for the purposes of Venusian exploration. This lighter-than-air rocket would be designed to sit above the acidic clouds for a period of around 30 days, allowing a team of astronauts to collect data about the planet's atmosphere.
While the surface of Venus would destroy a human, hovering above its clouds at an altitude of around 50 kilometres (30 miles) is a set of conditions similar to Earth. Its atmospheric pressure is comparable, and gravity is only slightly lower -- which would allow longer-term stays, effectively eliminating the ailments that occur during long-term stays in zero G. Temperature is about 75 degrees Celsius, which is hotter than is strictly comfortable, but would still be manageable. Finally, the atmosphere at that altitude offers protection from solar radiation comparable to living in Canada.

NASA wants to build a floating city above the clouds of Venus
Washington: NASA plans to send solar-powered airships to explore Venus' atmosphere and to eventually establish a permanent human colony in a floating cloud city above the Earth's nearest planetary neighbour.
Dale Arney and Chris Jones, from the Space Mission Analysis Branch of NASA's Systems Analysis and Concepts Directorate at Langley Research Center, in Virginia, have proposed that it may make sense to go to Venus before we ever send humans to Mars.
NASA's High Altitude Venus Operational Concept (HAVOC) mission aims to explore the atmosphere of Venus instead of exploring the surface.
At 50 kilometres above its surface, Venus offers one atmosphere of pressure and only slightly lower gravity than Earth.
Astronauts would also be protected from radiation in Venus's atmosphere, researchers said. The planet's proximity to the Sun provides it 40 per cent more solar power than the Earth gets, and 240 per cent more than that seen on Mars.
Since the orbits of Venus and Earth align over time, a crewed mission to Venus would take a total of 440 days using existing or very near-term propulsion technology, 'IEEE' reported.
But getting to Mars and back using the same propulsive technology would involve more than 500 days in space at a minimum.
HAVOC involves a series of missions, including a robotic mission first and then a crewed mission to Venus orbit with a stay of 30 days, and then a mission that includes a 30-day atmospheric stay.
Later missions would have a crew of two spend a year in the atmosphere, and eventually there would be a permanent human presence there in a floating cloud city.
A helium-filled, solar-powered airship would explore the planet's atmosphere. The robotic version would be 31 metres long while the crewed version would be nearly 130 metres long.

CHANGLUN: The Health Ministry will monitor the price of medicine to ensure patients are not burdened by expensive medicine after the implementation of the Goods and Services Tax (GST) in April next year.
Deputy Minister Datuk Seri Dr Hilmi Yahaya said the price of medicine in private hospitals and clinics may experience an increase of between one and two per cent, but not all.
He said several types of medicine were exempted from GST, such as panadol, which was commonly used in hospitals and clinics.
Patients seeking treatment from government hospitals need not worry about GST as the cost of medicine is funded by the government, he told a news conference after a health programme with the people at Kampung Tradisi here yesterday.
He said private clinics and hospitals in the country must comply with the ceiling price of medicine and medical treatment set by the Health Ministry so that it would not burden patients.
Should patients be imposed expensive medicine costs after the GST is implemented they can lodge a report with the Health Ministry.
Dr Hilmi said the ministry was also negotiating with medicine suppliers to standardise prices to avoid uncontrolled price hikes.
On the flood situation in the east coast, he said the ministry has deployed 322 personnel including 157 medical personnel stationed at mobile clinics.
So far none of the flood evacuees have experienced health problems such as food poisoning. There are enough personnel at flood relief centres to monitor the health of evacuees.
I advise flood victims, especially children, to avoid playing in flood waters as it may cause illness, he added. Bernama
