Partly Cloudy With A Chance Of Falling Satellites

Here we go again, this time it’s the German’s turn to randomly drop [expletive deleted] from orbit.

Falling German Satellite Poses 1-in-2,000 Risk of Striking Someone This Month

A big German satellite near the end of life is expected to plunge back to Earth this month, just weeks after a NASA satellite fell from orbit, and where this latest piece of space junk will hit is a mystery.

The 2.4-ton spacecraft, Germany’s Roentgen Satellite (ROSAT), is expected to fall Oct. 22 or 23.

The satellite will break up into fragments, some of which will disintegrate due to intense re-entry heat. But studies predict that about 1.6 tons of satellite leftovers could reach the Earth’s surface. That’s nearly half ROSAT’s entire mass.

There is a 1-in-2,000 chance that debris from the satellite could hit someone on Earth, though the likelihood of an injury is extremely remote, German space officials say. For German citizens, the risk of being struck is much lower, about 1 in 700,000.

All areas under the orbit of ROSAT, which extends to 53 degrees northern and southern latitude, could be in the strike zone of the satellite’s re-entry.

You’d think that by now, we’d have the technology to orbit powered drones with robotic arms that could guide these massive dead satellites into a controlled deorbit.

/joking about a 1 in 2000 chance of getting hit by tons of space junk moving at terminal velocity is all fun and games until someone actually gets hurt


Warp Speed?

Was Einstein wrong, can neutrinos blow through the speed of light stop sign?

Speedy Particles Put Einstein to the Test

An experiment purporting to show that subatomic particles can travel faster than light has scientists’ heads spinning. If confirmed, it would undermine key pillars of modern physics.

At a presentation in Switzerland, scientists said Friday they had recorded ghostlike particles, known as neutrinos, a tiny bit faster than light—an apparent breach of the cosmic speed limit set down by Albert Einstein more than a century ago.

. . .

Neutrinos are particles with almost no mass and no charge, and they can pass through ordinary matter unaffected. At any given moment, billions harmlessly stream through a person’s body.

In the experiment known as the Oscillation Project with Emulsion-Tracking Apparatus, neutrinos were measured as traveling slightly faster than light on a 450-mile trip from CERN near Geneva to the Gran Sasso underground lab in central Italy. The particles moved at a velocity just above the speed of light. That result was based on more than 15,000 neutrino events measured at the Italian lab, CERN said.

Are these results science fact or science fiction? Beats me. If it is true, it’s going to turn physics as we know it on its head.

/stay tuned, this is sure to be a hot topic of scientific debate for quite some time
