The student-run Cambridge University Spaceflight looks to reduce the cost of suborbital spaceflight, and frequently conducts experiments by launching high altitude balloons into near space. For their eighth Nova launch, they collaborated with a local science club. Club members ages 11-13 were invited to design insulating spacesuits to help the teddy bears survive the -53 °C temperature they would encounter during the flight.

“We want to offer young people the opportunity to get involved in the space industry whilst still at school and show that real-life science is something that is open to everybody” says Iain Waugh, chief aeronautical engineer of student-run Cambridge University Spaceflight.

“High altitude balloon flights are a fantastic way of encouraging interest in science. They are easy to understand, and produce amazing results,” said Daniel Strange, treasurer of CU Spaceflight.

The bears were launched on November 29th and returned to Earth on December 1st. Unfortunately, all four bears appear to have frozen while in space, but the cameras in the payload captured several striking images of their journey.

In 2004, the Bush administration introduced its “vision for space exploration,” which includes retiring NASA’s existing shuttle fleet and introducing Constellation, a new launching program using an updated capsule and rocket system. However, the administration, not wanting to inflate NASA’s budget, decided that manned space missions would go on a five-year hiatus, and that American astronauts should instead fly on Russian spacecraft.

But the recent political tensions between the US and Russia have complicated this plan. Although NASA does not doubt Russia’s commitment to transporting US astronauts, the US’s commitment to manned spaceflight will be greatly tested if relations with Russia continue to deteriorate. Following Russia’s military action in Georgia, Congress was stalled the bill to approve NASA’s purchase of seats on Russian spacecraft beyond 2011. The approval for the purchase of seats through 2016 did ultimately pass, but the incident prompted NASA administrator Michael D. Griffin to speak out against the current policy, which he called "unseemly in the extreme":

In an e-mail message he sent to his top advisers in August, Dr. Griffin wrote that “events have unfolded in a way that makes it clear how unwise it was for the U.S. to adopt a policy of deliberate dependence on another power.”

Griffin further suggests that the gap poses an unnecessary risk to the US space program:

“In a rational world, we would have been allowed to pick a shuttle retirement date to be consistent with Ares/Orion availability,” Dr. Griffin wrote. Within the administration, he wrote, “retiring the shuttle is a jihad rather than an engineering and program management decision.”

Griffin fears the consequences of any delay in the Constellation program, which comes at a time when China’s space program is rapidly advancing. Even if the current plans go according to schedule, the US will not return to the moon until 2020. Proponents fear that by then, the US will already be behind the curve.

It might be an inferiority complex. Soyuz capsules aren't renewable, but the Russians have been running them reliably into orbit for over forty years. NASA's space shuttle program's been going since 1981 and has had two major disasters.

But as The Washington Post's Marc Kaufman points out, they may also be nervous about relying on a program that's looked a little shaky of late:

Two consecutive chaotic and dangerous landings by Soyuz space capsules, including one with an American astronaut aboard, have NASA and space experts concerned about the spacecraft's reliability in ferrying astronauts to and from the international space station.

The worries are compounded by the fact that starting in 2010, when the space shuttle fleet will be retired, the United States will be entirely dependent on Russia's Soyuz capsules and rockets for transporting all astronauts and most cargo to the station — until at least 2015.

There's discussion later on in the article of additional funding to get NASA's new Orion capsule up and running before 2015, and that's a good idea. Way better than complaining about the one program on Earth that's reliable enough to keep human spaceflight going while it's American counterpart takes half a decade off.

At 102,800 feet, he will pass the current world record for highest altitude jump, set by Joseph Kittinger in 1960 (pictured). If exceeding Mach 1 doesn't tear him apart, he doesn't go into an uncontrollable spin and die, and he manages to survive lethally low temperatures, pressures, and oxygen levels, his name will go down in the history books. But why is he doing this? It's not just the record.

When Fournier jumps (it's more a question of 'if'; he's been trying this for years, but been foiled by weather and technical difficulties), the gear he'll have on will basically be a spacesuit. This isn't by accident.

When the Challenger space shuttle exploded during launch in 1987 it was just 11 miles above Earth's surface. If Fournier can survive his jump from more than twice that height, he believes he'll show the world that astronauts can return safely back to Earth from the edge of space. Spaceflight would become a lot safer, saving lots of live and possibly even helping to usher in the commercial spaceflight industry.
