NASA To Investigate Mysterious 'Space Ball'
redletterdave writes "In mid-November, a hollow space ball fell from the sky and crashed into the earth in Namibia, the African nation situated above South Africa and west of Botswana and Zimbabwe. Authorities recovered the sphere in a grassy village north of Windhoek, the country's capital. The hollow ball, which appears to be made of 'two halves welded together,' has a rough surface, a 14-inch diameter and measures 43 inches around. The strange globe created a crater 13 inches deep and almost 12.5 feet wide, but was found almost 60 feet from the landing spot. Paul Ludik, the police forensics director investigating the case, says the dense ball weighs 13 pounds and is made of a 'metal alloy known to man.' NASA and the European Space Agency will both help investigate the strange occurrence."
The Great Space Ball Mystery Has Been Solved
"For anyone wondering what it actually is, it's likely a 39-litre hydrazine bladder tank (based on its apparent size; there are also much larger hydrazine tanks)," he wrote. "They're used on unmanned rockets for satellite launches, which would explain why they're falling down in such a specific geographic footprint."
It's a COPV, see here or page 11 here. The wrapping has probably shielded it enough during the atmospheric re-entry and then ripped away, or it could be from lower altitude flight. In fact NASA and ESA have already studied this object, and most responsible news outlets have explained it along with the newsreport. The only real question is which mission or ship it is from, but unfortunately that might never be found out.
Why is NASA gonna look at the thing when somebody on the yahoo forums pointed out what it was and even provided a link? Sorry i don't have the link but, and excuse me if i don't get the make and model right as it was over a week ago, it was a hydrazine 104 liter tank, commonly used on some sats. anyway the guy provided a link and it looked pretty much dead on for what they found complete with the points on the end where the hoses go and everything.
Maybe NASA just doesn't have anything to do ATM with the end of the shuttle and the Russian rockets grounded?
ACs don't waste your time replying, your posts are never seen by me.
"Namibia, the African nation situated above South Africa "
I think you mean "to the north of South Africa." Otherwise, the real story here is how Namibia came to be floating over South Africa.
As someone else pointed out, most of the re-entered objects that are reasonably intact are spherical tanks. They're one of the few components of a spacecraft that are very solidly built. Most are titanium, or titanium wrapped in Kevlar, so they can take re-entry temperatures. Spheres have good re-entry aerodynamics. Nose cones have been hemispherical since the late 1950, after it was discovered that pointy noses look cool but don't work well. (See the X-3 Stilleto, an unsuccessful jet plane from 1952. Looks it was designed by George Lucas.)
