(Sounds like a Weekly World News headline, don’t it? 🙂

I’m praying that we will keep having clear skies until later tomorrow, ‘cuz at around 7:30 a.m. EDT (and 4:30 in the morning for y’all on the West Coast) NASA’s LCROSS mission will literally “shoot the Moon”.

LCROSS – short for “Lunar CRater Observing and Sensing Satellite -is looking for frozen water and other potentially cool stuff (no pun intended) that might be lurking in the shadows of Luna.  Tomorrow morning LCROSS will release a heavy projectile probe.  Not long afterward the probe will impact around the crater Cabeus A near the Moon’s south pole, and the expectant plume of vapor, dust and debris will be analyzed by the LCROSS main satellite (its orbit will carry it through the hoped-for cloud).

And depending on how much good junk gets kicked up we might...

For $8,000 you can purchase the TubeSat Personal Satellite from Interorbital Systems. Then you outfit your satellite however you like, and send it back to Interorbital Systems where it will be scheduled for orbital insertion aboard a NEPTUNE 30 vehicle (set to begin launch next year). Your satellite and 31 others will be hurled into an orbit 192 miles above the surface of the Earth, where it will function for a few weeks before safely re-entering the atmosphere and burning up. I’m thinking this might be a groovy thing for schools to look at: imagine the students of a science class beaming with pride as a satellite they designed is flying overhead and sending back telemetry!

Here’s the page at Interorbital Systems’ website for their TubeSat kit where you can order a satellite of your very own. And they even take PayPal!...

“…one giant leap for mankind.”

(And before anybody gives me grief over it, in the past few years audio analysis has determined that Armstrong did indeed say “step for a man” 🙂

Forty years ago today, on July 20th, 1969, astronauts Neil Armstrong, Michael Collins and Eugene “Buzz” Aldrin, with the assistance of a few hundred thousand of their good friends back on Earth, fulfilled an ages-old dream when Apollo 11 landed on the Moon. Armstrong was the first man to stretch his legs on the lunar surface, while Aldrin has the distinction of being the first person to “drain the main vein” on another world.

I didn’t know until this past year that before they began their “extra-vehicular activity” (in layman’s terms: they went outside the spaceship), that Aldrin also took communion on the Moon. At the time he was an elder of Webster Presbyterian Church and asked that ...

Thanks to a newly-tested and approved recycling system aboard the International Space Station, its long-term crews are now able to drink water recovered from urine, sweat and breath exhalation. It’s the first time that water has been acquired and imbibed in space in such a manner.

The new system takes the combined urine of the crew from the toilet, moves it to a big tank, where the water is boiled off, and the vapor collected. The rest of contaminants – the yucky brine in the urine – is thrown away, said Marybeth Edeen, the space station’s national lab manager who was in charge of the system.

The water vapor is mixed with water from air condensation, then it goes through filters, much like those put on home taps, Edeen said.

When six crew members are aboard it can make about six gallons from urine in about six hours, Edeen

When the Space Shuttle Discovery blasted into orbit two days ago, it might have taken this bat along for the ride. NASA technicians spotted the flying rodent clawed up against the vehicle’s external tank during inspections. And it was thought that it would eventually take fly off on its own.

But as Discovery roared from the launch pad, a tiny black speck was spotted clinging to the side of the tank. Sure enough, it was the bat.

Nobody has seen the bat since Discovery cleared the tower, but it was last seen still holding on to the vehicle.

Remember kiddies: hitchhiking can be dangerous…....

At least 600 pieces of spaceborne shrapnel are now plaguing the sky, no thanks to an unprecedented collision between two satellites in low-Earth orbit.

Early yesterday, 790 kilometers (490 miles) above Siberia, an inoperative Russian satellite called Cosmos 2251 smashed into Iridium33, a communications satellite. Ground radar is now tracking the hundreds of resulting bits of debris, hoping that none of it will smash into any other satellites or the International Space Station.

When asked which satellite was at fault, NASA scientist Nicholas Johnson said, “they ran into each other. Nothing has the right of way up there. We don’t have an air traffic controller in space. There is no universal way of knowing what’s coming in your direction.”

The good news, if there is any, is that Iridium Satellite LLC still has 64 satellites in unusually low orbit, relaying calls between special satellite phones (the U.S. Department of ...

Just six months after initial tests of the delivery vehicle, Iran has launched its first satellite into space. Early this morning a Safir-2 rocket lifted off from a launch facility somewhere in Iran, and shortly afterward successfully inserted the Omid satellite into low-Earth orbit.

Naturally, some folks on this side of the pond are worrying about Iran using its newfound spaceborne capability to rain nuclear fire down on Washington D.C. or Tel Aviv. But I don’t see too much to fret about… yet, anyway. What Iran did today is much more in the league of what the Soviets did with Sputnik. It’s a few magnitudes order of greater sophistication to build a working ICBM.

That said, as someone with a life-long interest in aerospace efforts – no matter who it is who’s doing the effortin’ – I shall be keeping an interested eye on Iran in the near future....

A few days ago during a spacewalk at the International Space Station, astronaut Heidemarie Stefanyshyn-Piper accidentally lost her bag of tools and it went floating away.

But don’t worry: Kevin Fetter of Brockville, Ontario found it last night! He was in his backyard with his satellite-observing gear, which was also armed with a good video camera. And Fetter not only spotted Stefanyshyn-Piper’s bag as it scooted past the star eta Pisces, he filmed it too…

Twenty years ago yesterday the Buran (shown landing at left), the Soviet Union’s answer to the American-made NASA space shuttle system, launched from Kazakhstan for its first test flight. It wound up being its only mission to date. A few years later the fall of communism left the program in limbo. The only flight-worthy Buran was destroyed during a roof collapse at the Baikonur facility in 2002, although a number of others were already in production and one is currently on display in a museum in Germany.

But with the space shuttle fleet due to be retired in less than two years, Russia Today is reporting that interest is being rekindled in the Buran system for use as a service vehicle for the International Space Station and perhaps other purposes as well. Despite its visual similarity to the American space shuttle, the Buran was in many ways the superior vehicle ...

There are ten more missions for the Space Shuttle fleet, as NASA has revealed the final slate of missions before the system is retired, after what will be 29 years of service. Endeavour is set to be the last one that will launch, with a mission scheduled for May 31, 2010 to bring spare parts to the International Space Station.

After Endeavour lands, NASA plans to begin using the new Ares launch vehicle (currently in preparation for testing), which will be carrying the Orion crew module. In the meantime, the station will be serviced by Japanese, ESA and Russian craft for supplies. Including the Soyuz, which it’s safe to say has gained far more respect in recent years than it ever had before in its long and admirable history… which predates the American-made Space Shuttle by fifteen years!

I’ve got mixed feelings about seeing the Space Shuttle program retired. On ...
