Watch Out! — another dead satellite falling to Earth this weekend

If you see a large glowing object plummeting from the sky late Saturday or early Sunday, duck.
A defunct European satellite called ROSAT is headed straight for Earth this weekend—and chances are even higher that a piece of space debris could hit someone than the odds placed on a NASA satellite that fell from orbit last month.
The German Aerospace Center, which led the development and construction of ROSAT, estimates that the chance of anyone being harmed by debris from the satellite is 1 in 2,000. For NASA’s UARS, the injury risk was roughly a third lower, at 1 in 3,200.
ROSAT is currently estimated to make an uncontrolled reentry during the early morning hours on Sunday, Greenwich Mean Time, said Heiner Klinkrad, head of the European Space Agency’s space debris office. But Klinkrad cautions that the satellite could enter Earth’s atmosphere up to 24 hours earlier or later than the estimated time…
Unfortunately, neither Klinkrad nor anyone else can say exactly where on Earth ROSAT is headed.
Debris could come down anywhere between 53 degrees north latitude and 53 degrees south latitude, an area that includes most of Earth’s land mass…That could be a worry, because the satellite’s 1.5-ton mirror is likely to survive the superheated trip through the atmosphere all the way to the ground, where it could make a major dent in whatever it strikes…
If bits of the satellite do land in a populated area, “they will be extremely hot,” added the German Aerospace Center’s Roland Gräve. “This is why we recommend not touching any satellite parts” that do make it to the ground.
And any ROSAT debris, no matter where it’s found, belongs to the German government, he said.
There are people like Jonathan McDowell from the Center for Astrophysics who are planning reentry parties. It’s tough keeping it on a schedule. He has a blanket email ready to go when he has concrete location numbers – just fill in the blanks and send it off into the Web.
We all can go “whoopee” while it crashes and burns.
Space junk almost clobbers International Space Station
A piece of space debris narrowly missed the International Space Station on Tuesday in a rare incident that forced the six-member crew to scramble to their rescue craft, space agency officials said.
The high-speed object hurtled toward the orbiting lab and likely missed it by just 1,100 feet. The crew moved to shelter inside two Soyuz spacecraft 18 minutes before the debris was expected to pass, NASA said.
“It was probably the closest object that has actually come by the space station,” said the US space agency’s associate administrator for space operations, Bill Gerstenmaier. “We didn’t have any information that it was coming until it was very, very close…”
They spent about half an hour in the Russian space capsules and then went back to their regular day…
Space experts say such events are only becoming more frequent as the amount of waste — from nuts and bolts to rocket parts — is on the rise due to everything from basic wear and tear to controversial military testing.
Millions of chunks of metal, plastic and glass are whirling round Earth, the garbage left from 4,600 launches in 54 years of space exploration.
The collision risk is low, but the junk travels at such high speed that even a tiny shard can cripple a satellite costing tens of millions of dollars…
The ISS is currently manned by three Russians, two Americans and a Japanese astronaut…The crew usually stays for six-month stretches aboard the space station.
Phew! Ultra-high-speed impact even with a small object is worse than being shot. In the vacuum of space it’s easily deadly.
Germany will launch trash-collector robots to sweep space junk

Robots that rescue failing satellites and push “dead” ones into outer space should be ready in four years, it has emerged. Experts described the development by German scientists as a crucial step in preventing a disaster in the Earth’s crowded orbit.
Last year it was reported that critical levels of debris circling the Earth were threatening astronauts’ lives and the future of the multibillion-pound satellite communications industry. But senior figures at the German Aerospace Centre (DLR) told the Observer they have been given the go-ahead to tackle a crisis that will come to a head in the next five to 10 years as more orbiting objects run out of fuel.
Their robots will dock with failing satellites to carry out repairs or push them into “graveyard orbits“, freeing vital space in geostationary orbit. This is the narrow band 22,000 miles above the Earth in which orbiting objects appear fixed at the same point. More than 200 dead satellites litter this orbit. Within 10 years that number could increase fivefold, the International Association for the Advancement of Space Safety has warned.
What a terrific idea!
The US and Russia should pick up the tab since we launched most of the crap that’s up there.
Chickenshit commentary of the week!
Do you ever tire of articles, op-ed pieces, commentary from TV Talking Heads that avoid the point altogether? Here’s this week’s best example – Bob Greene at CNN offering a “humorous” commentary about the US Postal Service:

You seemed a little bit interested in last Sunday’s column: the one about the prospect of Saturday mail delivery being eliminated by the U.S. Postal Service.
That is what Postmaster General John E. Potter has asked Congress to authorize. Because of a budget crisis and a drastic decline in the number of items Americans send through the mail each year (an estimated 20 billion fewer items mailed this year alone), Potter wants to stop delivering mail on Saturdays.
Along with last week’s column, there was a feature where readers were invited to cast their votes on the subject (not a scientific poll, as they say; I think this means that Albert Einstein wasn’t counting the ballots).
More than 397,000 of you took the time to vote. The question was: “Would you miss Saturday mail if the Postal Service stopped delivering it?…”
Sixty-eight percent of you said you would not miss the Saturday mail if it stopped coming. Only 32 percent of you said you would miss it…
Postmaster General Potter says that getting rid of Saturday delivery would save more than $3 billion a year. My guess is that not only are they going to have to do away with Saturday mail — the time is probably coming when delivery on other days of the week will disappear, too.
So the question is not whether the days of mail delivery will be curtailed. It’s whether we will be happy about it.
The real problem hasn’t changed in 50 years. Junk mail doesn’t pay for itself.
The sleazy junk mail factories should be subsidizing the post office for all of us! From Capital One to Publishers Clearinghouse to my local Chevy Dealer’s Lucky Ignition Key – do you think these cruds look forward to shipping “the latest, greatest cookbook offer” to my front door via UPS or FedEx?
Congress will likely discover some populist lie acceptable to both Republican and Democrat lobbyists to maintain USPS subsidies. You wouldn’t want America’s biggest freeloaders to carry their own weight would you?
What I also don’t expect is an honest challenge to the corporate status quo from a smiley flack working for Time-Warner.
