NASA still on course for two shuttle missions in 2004 but warns of 'no guarantees'
NASA's return-to-flight program is working towards two shuttle launches in late 2004 but caution remains the watchword for the shuttle team. Two shuttles, Atlantis and Discovery are being prepared for a flight  window that begins in September 2004.  But there's still a long way to go. Atlantis is without several major components that were removed for testing, while Discovery is being re-assembled after major maintenance. Shuttle Program Manager Bill Parsons says the overriding concern remains safety.

SpaceShipOne Soars to Sixth Flight Test
Regarded by many as the favorite to win the X Prize, SpaceShipOne, the creation of aviation legend Burt Rutan, has successfully carried out a sixth successful test flight. A veil of secrecy has descended on the project's headquarters at Scaled Composites in Mojave, California. Rutan is believed to be funded by Microsoft co-founder Paul Allen. He certainly has more cash than his fellow competitors - but does that guarantee success. We report on White Knight and SpaceShipOne's race for victory.

Canadian Arrow prepares for launch with full astronaut team
After a worldwide search for a team of astronauts, Canadian Arrow has now selected the team to lead its quest for X Prize victory. The Canadian Arrow is a 54-ft long, two-stage, three person sub-orbital rocket with the second stage doubling as an escape system.  The four solid rockets can be ignited at any point during the flight, including before launch, to initiate a zero altitude launch pad abort or an in-flight recovery sequence. Listen now as Canadian Arrow team leader Geoff Sheerin gives us the latest on his group's plans to claim this historic prize.

DaVinci Project use massive Helium Balloon to launch their Space Quest
The da Vinci Project will launch its spacecraft 'Wild Fire' from the world's largest helium balloon. The rocket will be tethered below the balloon and lifted over the course of an hour to an altitude of 80,000 feet. The 10,000 pound thrust, liquid oxygen, kerosene engines will fire the first stage and the rocket will fly an initial angular trajectory to clear the balloon. The rocket will reach a maximum speed on both its ascent and re-entry of Mach 4, or 2,650 mph. A flyable parachute will be deployed at 25,000 feet and the rocket will descend under control, guided by GPS, to a predetermined landing zone. Team Leader Brian Feeney tells us why DaVinci would be proud.

Thunderbird reaches for the X Prize Stars - Steve Bennett
Starchaser Industries in the UK is aiming for X Prize victory with ‘Thunderbird.’ The vehicle will begin her ascent in a vertical orientation using solid boosters and liquid rocket engines. At higher altitudes the main liquid oxygen/kerosene rocket engine will take over, becoming the major propulsive force in the now rarefied atmosphere. Starchaser’s founder Steve Bennett gives us the lowdown on Britain’s bid for the stars.

Flying high X-15 Style - David Ashford
Ascender is designed to be the first sub-orbital aeroplane since the X-15. Bristol Spaceplanes plan for Ascender to carry a crew of two and two passengers to space and back. Passengers will experience two minutes of weightlessness, will see superb views of Earth, and will see the sky turn black even in daytime. It takes off from an ordinary airfield using its turbofan engine and climbs at subsonic speed to a height of 8 km. The biggest drawback is lack of cash – but that’s not curbing the enthusiasm of Ascender’s creator David Ashford.
