Nasa super pressure balloon cleared for takeoff

NOT RIGHT: Nasa campaign manager Dwayne Orr says conditions have to be perfect for the balloon launch.

SUPER-PRESSURE: A Nasa balloon similar to the one to be launched at Wanaka.

A Nasa balloon launch attempt has been cancelled because of opposing winds, disappointing a small crowd gathered at Wanaka Airport.

The Nasa super-pressure balloon was due to lift off between 8am and 10am on Monday in Wanaka.

Mission boss Debbie Fairweather said it could be Thursday or Friday before another launch was attempted.

"We had a test run and it was a no show . . . we are used to this," she said.

"It is part of the nature of our business."

In Sweden, the team waited for a month and a half to launch and did 24 early-morning starts in a row before conditions were right.

NASA Test Fires Largest Rocket Ever; SpaceX Yawns

Posted on by

NASA wants to put a man on Mars . For the time being, that looks like a giant leap. But the good news is that last week, the National Aeronautics and Space Administration took at least one small step in the direction of Mars.

Artist's conception of what SLS will look like upon completion. Those two "little" rockets on the sides? Those are the boosters that NASA tested last week. Source: NASA .

Out in the Utah desert, NASA successfully test fired a new rocket engine capable of lifting American spaceships to the Moon, the Asteroid Belt, and even to Mars. Built by the rocket scientists at Orbital ATK , it burns an amalgam of powdered aluminum fuel, oxidizer, and binding agents. Clocking in at a remarkable 177 feet talland producing about 3.6 million pounds of thrust (22 million horsepower) during its two-minute burn, the new solid-fuel Space Launch System rocket booster is the biggest rocket engine we've ever built.

If you build it, they can go (to Mars) NASA plans to conduct another test firing early next year before putting the boosters to work with an actual launch, scheduled for 2018. Two boosters will be needed for NASA to launch its new Boeing -built Space Launch System into space, adding oomph to the SLS's core engine group comprising of four RS-25 engines manufactured by GenCorp .

Combined, all these engines will permit SLS to lift payloads as great as 70 metric tons into low Earth orbit (LEO). And once that's accomplished, NASA plans to double the power, adding enough engines to lift 130 tons -- all the way to Mars.

But here's the kicker: When they get there, they may find that SpaceX has already set up camp .

SpaceX has the T-shirt. Now it just needs to build the spaceship. Photo: SpaceX .

Occupying Mars While NASA and its old-industry partners -- Orbital ATK and GenCorp, Boeing and Lockheed Martin -- are all busily trying to assemble an SLS for a trip to Mars 25 years from now, privately owned SpaceX is making leap-ahead progress... today.

SpaceX already advertises on its website one rocket capable of lifting 53 tons of payload to LEO. That's about 75% of what SLS will do when it's ready... three years from now. And the modular way in which SpaceX is building its Falcon 9 family of spacecraft -- nine engines to a booster, one booster for a basic Falcon 9 rocket, three boosters for a Falcon Heavy -- suggests that, assuming my algebra is right, by adding two more boosters to the basic Falcon configuration, a Falcon "superheavy" rocket could lift as much as 88 metric tons -- 26% more than SLS.

And that's not all. As SpaceX CEO Elon Musk informed investors in a recent chat on Reddit, SpaceX is hard at work adding an order-of-magnitude improvement on the Falcon design. Dubbed "Raptor," Musk says that the new rocket he's building for a manned Mars mission will be big enough to send 100 tons of payload, and/or 100 live human colonists -- not just into orbit, but all the way to Mars .
