Send a message to space

I stumbled across this site on Twitter the other day. http://www.sentforever.com/index.cfm

Their ad reads, "SentForever transmits your personal message into deep space. Once that message starts traveling, it will continue for an eternity. If you've ever wanted to give someone special a personal and very unique gift, why not send them a message that will last forever."

The way it works is, you write your personal message and submit it to their website. Then they transmit the message into space via a large radio telescope. They send a certificate to the person you want to dedicate or send the message to, along with a personal tracking number so you can track how far the message has traveled into deep space. You can also receive e-mail updates to find-out when your message passes key milestones if you want.
This service normally costs �9.95 (approximately 20 US Dollars). Right now they are offering free messages, so I tried it out just so see how it works and what you get for your money.
It works pretty much as advertised. I wrote a message to send into space "You are not alone. There is life in the universe," submitted it and had it sent to my wife. The following day, they sent me an email notifying me of the transmission, along with a link to view the progress of my message into space at the speed of light. I checked in as I'm writing this and can see how far my message has progressed to date-

This message from Mike Simonsen was transmitted into deep space on 20 February 2009 at 04:47 UK time. Going at the speed of light, your message has traveled 37,639,662,291 miles to date.

I'm usually not in favor of doing stuff like this. I really have a problem with the companies that sell 'name a star' services. If you've ever had the uncomfortable experience of someone coming up to you at an observatory open house and asking to see 'the star named after my dear departed Aunt Mary', you know why. It's a scam, and one that can hurt people when they are told some anonymous star with an obscure catalog name can not really be named after Aunt Mary, no matter how much money they plunk down.

Then there are the people who sell real estate on the Moon or Mars. If this is done in good faith and humor as a fundraising tool for a non-profit, fine. But if it's done to make a profit off of gullible, uninformed people, I think they should be jailed.

This service though, is something different. These people actually can send a message into space that will travel forever. Sending a message that is verified electronically to a loved one as a gift or Valentine's Day card doesn't hurt anyone.

I can see how this could be used to demonstrate the scale of the solar system, our immediate stellar surroundings and the scale of the universe. How many miles are in a light year? How long will our message take to get to Pluto? How long to catch up to the Voyager spacecraft? How long to get to the nearest stars?

You could write a short eulogy for a friend or relative and have it transmitted into space, or write a message from the heart and send it to a girlfriend or spouse. Just remember, if you're going to send a love note, you can't take it back three years from now when you find out she has fangs and a mental disorder. A tattoo you can remove with some difficulty. This is forever...

And if you're going to send it to your wife, you might want to make your message a little more romantic than mine. Admittedly, I was trying to think of what it is I'd actually want to hear if I picked up a signal from deep space. Confirmation of alien intelligence, for sure!!

Now I may have to spring for the twenty bucks to send something romantic.

Tracking Penguin Poop From Space


This was just too interesting at first glance to ignore when it whizzed into my Google reader.

British scientists studying emperor penguin colonies in Antartica have come up with a clever way of spotting the birds from space. Apparently, the penguins themselves are difficult to make out in satellite imagery, but the places on the ice that they call home for months at a time eventually get pretty dirty. Penguin poop can be seen from space!

"We can't see actual penguins on the satellite maps because the resolution isn't good enough," said mapping expert Peter Fretwell. "But during the breeding season the birds stay at a colony for eight months. The ice gets pretty dirty and it's the guano stains that we can see."

These guys are prety excited about poop. It has helped them locate 10 new colonies of penguins. Now that they know where the penguins are, they can get to the more difficult task of counting the birds in order to track population movements and changes over time. Amazing what you can do with satellites, isn't it?

The Summer We Flew to the Moon

In July this year, I gave a talk at my local astronomy club, the Warren Astronomical Society. Part of each meeting is set aside to discuss astronomy related news and upcoming events. One story was about Russian cosmonauts who had just emerged from an isolation experiment intended to study the effects of being cooped up together on a mission to Mars. The other big story was the approaching 40th anniversary of the historic Apollo moon landing.

These stories got me thinking about when I was 12 years old and my friend, Bob Dostie, and I decided to build our own isolation experiment. We had read about students building space capsules to test their ability to withstand the rigors of being confined in a small space, much like the Apollo astronauts of the day were enduring, for up to several weeks at a time. Most or all of the experiments we read about took place in schools with permission and support from the teachers, staff and parents. But it was summer vacation, so Bob and I decided to build our own capsule in the attic over the garage at my house.

Our home was a two-story colonial back then, with an attached two-car garage. My dad had a workshop and storage shelves, and he stored his boat and his dragster in there. The attic over the garage was accessed through an approximately 2x4 foot panel that you pushed up into the attic from on top of a stepladder. If you wanted to get up in the attic you had to lift yourself up from atop the ladder, and drag yourself onto the wooden floor, much like climbing out of a pool, except without the advantage of buoyancy.

Getting down was much more perilous. You had to hang out over the edge of the hole, line yourself up with the top of the ladder and lower yourself down onto a step with very little margin for error. I shudder to think about it now, but we were kids; we did it all the time. It was up and down this ladder we hauled all our materials and accessories for the space capsule.

We had the seat and back from an old car that we adapted into our space lounger. We angled the back to resemble the pictures we�d seen of the astronaut seats in the Mercury and Apollo capsules. We even had seat belts to secure us, for blast off and landings.

We scrounged together hundreds of electrical switches, knobs and lights and created a massive two-man control panel. Some of the lights and switches actually did things and lit up. We used the pitch of the attic roof to our advantage and had the control panel just over our heads as we laid on the astronaut lounger in space travel orientation.

Bob�s dad worked for the phone company, so we were able to �borrow� a couple hundred feet of wire and two phones that we actually hooked up from the house to the space capsule so we could call �mission control� for more soft drinks and sandwiches when we needed them. We had electricity; a cooler, a radio, a fan and we spent weeks working on our experiment getting ready for the big day.

We thought we could last for about a week, but decided we�d be happy if we made it for three or four days the first time we traveled into space. We calculated how many sodas, sandwiches, bags of chips, Twinkies and other snacks we would need to take with us to the Moon and back, and stocked up. All conditions were go and we triumphantly blasted off Monday morning after breakfast.

The first day wasn�t too bad. It was kind of like camping in the attic. We hung out, played astronaut, listened to the radio, ate our sandwiches and snacks and drank our sodas. It wasn�t long before we had to use our space toilet to eliminate those sodas, but we were pretty satisfied with the plastic bag we�d rigged up to be our space potty.

After the sun went down, we got the call from mission control to see if we were still okay. Things couldn�t be better as far as we were concerned, so we spent our first night in the dark in the attic over the garage.

The next morning we had to empty our bladders again first thing before breakfast, and we noted with some concern that we had seriously underestimated the volume of pee our space toilet could hold. It was shortly after lunch that our inadequate space potty became a serious threat to the mission. Bob had to poop.

I seem to remember that I had to poop too, but there was no way I was sitting on that thing, so I had resolved to just hold it until it was time to call off the mission, and I would just run into the house as fast as I could when we decided we just couldn�t take it any more.

But Bob really had to poop.

Finally Bob said, �the heck with this, let�s call it off. I have to go now.� So we pulled up the attic door and discovered to our horror that the ladder was not there any more. Someone had put it away, and there was no way we could risk jumping down from there while still within Earth�s gravity!

We sent out a desperate call to mission control, but no one was home. It was the middle of a fine summer day and everyone else was off doing summer things, outdoors, in the fresh air. We were not only jealous, we were stuck in the attic, I mean, space capsule.

Bob started to cry.

I tried to reassure him. �How bad can it be? C�mon, just get it over with and we can go on with the mission.� Eventually, reluctantly, Bob braved it and deposited several loud, stinky astronaut bombs into the space toilet.

Now we had a new problem. Our air supply was severely compromised.

The stench wafting out of the space toilet was overpowering, and it was getting worse as the mid-day sun beat down on the roof of the attic. We sat for a long time in quiet humiliation, listening to the fan pitifully trying to blow the astronaut stench out the attic vent above the astronaut control panel. I tried sealing up the bag and moving it closer to the door, and we thought about lowering the bag down with a rope to get it out of the spaceship, but we hadn�t thought to bring a rope on our lunar mission. So we just sat there with an alarmingly large bag of urine, tissue and feces waiting for mission control, or anyone, even aliens, to rescue us from our plight.

After what seemed like hours and hours, we heard someone open the garage door below us and cried out for help. It was my little brother, Dale. My God, I was never so happy to see him ever in my life as that moment. We begged him to get the ladder and come up to collect our �garbage�. We didn�t dare tell him what it really was, because the smell had subsided somewhat by now, and we had decided if he would just take the astronaut waste bag away we would continue the mission.

He pulled the ladder over to the hole, climbed up, and peered into the space capsule. He was only eight years old at the time, so his bespectacled blue eyes just barely cleared the opening to the attic from the top of the ladder. I told him if he would take out our garbage I would let him play spaceship with us sometime when we were done with the mission. He said okay and I carefully handed him the plastic kitchen bag full of bad things.

That was the day I learned never to lie to my little brother Dale. He took the bag and headed down the ladder. When he got half way down he promptly threw the bag out into the middle of the garage, thinking it was just solid waste. Bob and I stared at each other in horror, as we understood immediately what the sickening sound Ka-SPLASH meant.

The space potty receptacle bag had exploded in the garage like a water balloon full of sewage. There was pee and poop and tissue all over the floor, the boat trailer and my dad�s drag racer. Our mission was over.

We never did make it to the moon, and we didn�t spend a lot of time up in the attic after that. I guess the glow had worn off the idea. And even though we played baseball, rode our bikes, went swimming and exploring the woods together the rest of that summer, Bob and I never became the best of friends. I lost track of him and most of my neighborhood friends long ago, but I�ll bet Bob, wherever he is, remembers the summer we tried to fly to the moon.
