Another small step: Nasa unveils Orion capsule bound to take astronauts to Mars
It may look a little underwhelming but this little craft's lofty goal is to take astronauts out of an Earth orbit for the first time since the 1970s - and possibly land man on Mars.
In front of more than 450 guests and dignitaries, Nasa officially unveiled the Orion crew capsule at a 'welcoming ceremony' at the Kennedy Space Center in Florida.
Despite funding and planning cuts at the space agency, the capsule is part of a concerted effort to kickstart a new era in deep space exploration by humans.

This capsule is not a mock-up or scale model but a working piece of space kit that is bound for an unmanned test flight in 2014.
It will be shot into orbit atop a Delta 4 rocket, speeding around the Earth 3,600 miles above the surface - which is about 15 times further out than the current International Space Station orbit.
After two full orbits, the capsule will re-enter the atmosphere at more than 20,000mph to test the craft and its heat shield.
Lori Garver, Nasa's deputy administrator, told the assembled crowd: 'This starts a new, exciting chapter in this nation’s great space exploration story.'

Over the next 18 months, engineers and technicians at the space centre will install avionics, instrumentation, flight computers and the heat shield – slowly building and filling up the pressure shell into a fully functioning spacecraft.
U.S. Senator Bill Nelson, of Florida, was instrumental in getting congressional funding for Nasa to build the capsule - officially titled the Orion Multipurpose Crew Vehicle (MPCV).
More money is earmarked for the launch vehicle, a Space Launch System (SLS) booster rocket similar in size and design to the Saturn V rockets of the Apollo missions.

Clearly proud of his achievement - and echoing President John Kennedy's bold claim to put a man on the moon by the end of the 1960s - Senator Nelson proclaimed: 'Ladies and gentlemen, we’re going to Mars.
'Without question, the long-term goal of our space programme, human space programme right now is the goal of going to Mars in the decade of the 2030s.
'We still need to refine how we’re going to go there, we’ve got to develop a lot of technologies, we’ve got to figure out how and where we’re going to stop along the way.
'The president’s goal is an asteroid in 2025. But we know the Orion capsule is a critical part of the system that is going to take us there.'

The first real test of the craft,
Exploration Flight Test 1 (EFT-1), will be in two year's time. Crammed
with instrumentation and sensors, Nasa will learn whether Orion can
withstand the enormous stresses of launch, orbit and re-entry.
There are mission plans for pairing Orion capsule with the mighty SLS rocket in 2017 - even for a crewed orbit of the moon in 2021.
But the major hurdle for Nasa to overcome is government funding.

As Ken Kremer writes in an article about the Orion welcoming party for Universe Today: 'In these lean times, there is no guarantee of future funding.
'Nasa’s budget has already been significantly chopped - forcing numerous delays and outright mission cancellations on many NASA projects, including: the outright termination of NASA next Mars rover; multi-year delays to the commercial crew programme; and prior plans to launch a crewed Orion to orbit as early as 2013.'
