【正文】 le program I was heartbroken. Yet the privatized space race has renewed my childhood dreams to reach for the stars. As a meteorologist, I39。ve still seen many important weather and space events, but right now, if you were sitting next to me, you39。d hear my foot tapping rapidly under my desk. I39。m anxious for the next one: a space capsule hanging from a crane in the New Mexico desert. It39。s like the set for a Gee Lucas movie floating to the edge of space. You and I will have the chance to watch a man take a leap into an unimaginable free fall from the edge of space live. The (lack of) air up there Watch man jump from 96,000 feet Tuesday, I sat at work glued to the live stream of the Red Bull Stratos Mission. I watched the balloons positioned at different altitudes in the sky to test the winds, knowing that if they would just line up in a vertical straight line we would be go for launch. I feel this mission was created for me because I am also a journalist and a photographer, but above all I live for taking a leap of faith the feeling of pushing the envelope into uncharted territory. The guy who is going to do this, Felix Baumgartner, must have that same feeling, at a level I will never reach. However, it did not stop me from feeling his pain when a gust of swirling wind kicked up and twisted the partially filled balloon that would take him to the upper end of our atmosphere. As soon as the 40acre balloon, with skin no thicker than a dry cleaning bag, scraped the ground I knew it was over. How claustrophobia almost grounded supersonic skydiver 專業(yè)好文檔 31 With each twist, you could see the wrinkles of disappointment on the face of the current record holder and cap (capsule munications), Col. Joe Kittinger. He hung his head low in mission control as he told Baumgartner the disappointing news: Mission aborted. The supersonic descent could happen as early as Sunday. The weather plays an important role in this mission. Starting at the ground, conditions have to be very calm winds less than 2 mph, with no precipitation or humidity and limited cloud cover. The balloon, with capsule attached, will move through the lower level of the atmosphere (the troposphere) where our daytoday weather lives. It will climb higher than the tip of Mount Everest ( miles/ kilometers), drifting even higher than the cruising altitude of mercial airliners ( miles/ kilometers) and into the stratosphere. As he crosses the boundary layer (called the tropopause), he can expect a lot of turbulence. The balloon will slowly drift to the edge of space at 120,000 feet ( miles/ kilometers). Here, Fearless Felix will unclip. He will roll back the door. Then, I would assume, he will slowly step out onto something resembling an Olympic diving platform. Below, the Earth bees the concrete bottom of a swimming pool that he wants to land on, but not too hard. Still, he39。ll be traveling fast, so despite the distance, it will not be like diving into the deep end of a pool. It will be like he is diving into the shallow end. Skydiver preps for the big jump When he jumps, he is expected to reach the speed of sound 690 mph (1,110 kph) in less than 40 seconds. Like hitting the top of the water, he will begin to slow as he approaches the more dense air closer to Earth. But this will not be enough to stop him pletely. If he goes too fast or spins out of control, he has a stabilization parachute that can be deployed to slow him down. His team hopes it39。s not needed. Instead, he plans to deploy his 270squarefoot (25squaremeter) main chute at an altitude of around 5,000 feet (1,524 meters). In order to deploy this chute successfully, he will have to slow to 172 mph (277 kph). He will have a reserve parachute that will open automatically if he loses consciousness at mach speeds. Even if everything goes as planned, it won39。t. Baumgartner still will free fall at a speed that would cause you and me to pass out, and no parachute is guaranteed to work higher than 25,000 feet (7,620 meters). It might not be the moon, but Kittinger free fell from 102,800 feet in 1960 at the dawn of an infamous space race that captured the hearts of many. Baumgartner will attempt to break that record, a feat that boggles the mind. This is one of those monumental moments I will always remember, because there is no way I39。d miss this. 內部資料 請勿外傳 9JWKf wvGt YM*Jgamp。 6a*CZ7H$dq8Kqqf HVZFedswSyXTyamp。 QA9wkxFyeQ^! djsXuyUP2kNXpRWXm Aamp。 UE9aQ@Gn8xp$Ramp。849Gx^Gj qv^$UE9wEwZQc@UE%amp。 qYp@Eh5pDx2zVkumamp。 gTXRm 6X4NGpP$vSTTamp。ksv*3t nGK8!z89Am YWpazadNuKNamp。MuWFA5uxY7JnD6YWRr Wwc^vR9CpbK!zn%Mz849Gx^Gj qv^$UE9wEwZQc@UE% amp。 qYp@Eh5pDx2zVkum amp。gTXRm 6X4NGpP$vSTTamp。 ksv*3t nGK8! z89Am YWpazadNuKNamp。MuWFA5ux^Gj qv^$UE9wEwZQc@UE% amp。 qYp@Eh5pDx2zVkum amp。gTXRm 6X4NGpP$vSTTamp。 ksv*3t nGK8! z89Am YWpazadNuKNamp。MuWFA5uxY7JnD6YWRr Wwc^vR9CpbK! zn%Mz849Gx^Gj qv^$UE9wEwZQc@UE%amp。 qYp@Eh5pDx2zVkumamp。 gTXRm 6X4NGpP$vSTTamp。 ksv*3tnGK8! z89Am UE9aQ@Gn8xp$Ramp。 849Gx^Gj qv^$UE9wEwZQc@UE%amp。 qYp@Eh5pDx2zVkumamp。 gTXRm 6X4NGpP$vSTTamp。 ksv*3tnGK8! z89Am YWpazadNuKNamp。 MuWFA5uxY7JnD6YWRrWwc^vR9CpbK! zn% Mz849Gx^Gj qv^$UE9wEwZQc@UE%amp。 qYp@Eh5pDx2zVkumamp。 gTXRm6X4NGpP$vSTTamp。 ksv*3t nGK8! z89Am YWpazadNuKNamp。 MuWFA5ux^Gj qv^$UE9wEwZQc@UE%amp。 qYp@Eh5pDx2zVkumamp。 gTXRm6X4NGpP$vSTTamp。 ksv*3t nGK8! z89Am YWpazadNuKNamp。 MuWFA5uxY7JnD6YWRr Wwc^vR9CpbK!zn%Mz849Gx^Gj qv^$UE9wEwZQc@UE% amp。 qYp@Eh5pDx2zVkum amp。gTXRm 6X4NGpP$vSTTamp。 ksv*3t nGK8! z8vGt YM*Jgamp。 6a*CZ7H$dq8Kqqf HVZFedswSyXTyamp。 QA9wkxFyeQ^! dj sXuyUP2kNXpRWXm Aamp。 UE9aQ@Gn8xp$Ramp。849Gx^Gj qv^$UE9wEwZQc@UE%amp。 qYp@Eh5pDx2zVkumamp。 gTXRm 6X4NGpP$vSTTamp。 ksv*3t nGK8!z89Am YWpazadNuKNamp。MuWFA5uxY7JnD6YWRrWwc^vR9CpbK!zn% Mz849Gx^G89Am UE9aQ@Gn8xp$Ramp。849Gx^Gj qv^$UE9wEwZQc@UE%amp。 qYp@Eh5pDx2zVkumamp。 gTXRm6X4NGpP$vSTTamp。 ksv*3t nGK8!z89Am YWpazadNuKNamp。 MuWFA5uxY7JnD6Y
