Cut The Space Mustard

Tuesday, March 31st, 2009

And he said, Whereunto shall we liken the kingdom of God? or with what comparison shall we compare it?
It is like a grain of mustard seed, which, when it is sown in the earth, is less than all the seeds that be in the earth:
But when it is sown, it groweth up, and becometh greater than all herbs, and shooteth out great branches; so that the fowls of the air may lodge under the shadow of it.

 

 

 

Interesting how a new partnership to grow plants on the Moon, announced last week, will focus on the mustard seed:

The prototype unveiled on Friday is a metal-reinforced glass dome that is some 9 centimetres in diameter and 30 centimetres high, enough space to grow roughly six plants.

But the enclosure will need to be modified to protect plants from the vagaries of space radiation and extremes in temperature on the lunar surface, which can range from a frigid -170 °C to just above 100 °C.

To avoid the cold of the lunar night, which lasts for 14 Earth days, the team decided to send up a fast-growing member of the mustard family. The mustard plant can grow from seed to flower over the course of a single lunar day, or two Earth weeks.

But a number of details still need to be worked out. It is not clear how the seeds themselves will be planted. Because ordinary soil is easily jostled, the team is considering using a stickier substrate, like seaweed-derived agar, to grow the plants.

 

Will the lunar mission be led by Col. Mustard, too? I don’t have a clue.

 

 

Good-bye IP-PRIME, Hello ViP-TV

Monday, March 30th, 2009

 

There it was, a punch in the nose to fans of IPTV in the U.S. back in December when SES announced it was shutting down IP-PRIME

“In line with its plan, IP-PRIME has contracted IPTV signal delivery agreements with 70 small telecom operators, of which 37 have so far reached commercial stage.  However, with a subscriber base of less than ten thousand at the end of November and after more than 2 years of service, the consumer uptake is insufficient to justify continuing operations,” said Rob Bednarek, President and CEO of SES AMERICOM-NEW SKIES.

The IP-PRIME service will continue to operate until July 31, 2009.  This will offer telecom operators an opportunity to orderly transfer their services and SES AMERICOM, in collaboration with third parties involved in the service, to seek the best option to transition the business.

Sure, it was costing lots in resources (people and money) to keep the C-band based service running. It was ahead of all competitors in the U.S., but it was tough to convince SES management it was worth the continuing effort. Inside Americom, people thought the way out of this was to sell the service and related assets to EchoStar, who had their own Ku-band based service, ViP-TV. Ironically, using the AMC-16 satellite they were leasing.

SES may not get to sell it after all. EchoStar launched an IP-PRIME Conversion Program last week:

EchoStar Satellite Services, a division of EchoStar Corporation (NASDAQ: SATS), announced today the company’s IP-Prime Conversion Program, designed to provide continued delivery of video transport services for telco IP headend facilities across the United States. Commercial transport provider IP-Prime has previously announced it will discontinue its video transport service to headend facilities by July 31, 2009. EchoStar’s IP-Prime Conversion Program provides qualified customers with EchoStar’s ViP-TV(TM) transport service, replacement IDC satellite receivers and a standard professional installation, including compatible LNBs, a satellite dish re-point, cabling and connectors.

Interesting development, but not unforeseen. With IPTV subscibers doubling to 3.8 million in North America, EchoStar’s timing is typically very good.

Not surprisingly, Western Europe is still the leading IPTV region in the world, but regions such as North America continue to show their own strong growth paces. That’s the word from research firm Point-Topic and the Broadband Forum, who announced their fourth-quarter 2008 numbers at the IPTV World Forum in London this week.

Western Europe had more than 10.3 million IPTV subscribers at the end of 2008. North America, despite the U.S. being Ground Zero for the recession, saw its IPTV subscriber numbers grow a whopping 113 percent to more than 3.8 million from the end of 2007 to the end of 2008. Worldwide, IPTV subscribers totaled 21.7 million at the end of 2008, representing growth of 63 percent from the previous year.

DIY Friday: Old Dish Signal Booster

Friday, March 27th, 2009

 

 

We’ve blogged about the "cantenna" and repurposing old parabolic dishes for boosting WiFi signals. With people switching from direct-broadcast satellite TV (DISH and DirecTV) to Verizon FiOS, AT&T Uverse, back to cable TV or just cutting all pay television services and using free over-the-air HDTV, you might want to consider using your old antenna for something else.

Birdbaths and Spartan shields are OK ideas, but using it to boost cell phone or WiFi signals might be more useful. We’ve got a place up in the mountains and finding a good cell signal can be tricky.

Via Instructables, here’s the solution:

While working in my yard one afternoon I noticed an old satellite TV dish on top of a pole in my backyard. It had been left there by the previous residents. Suddenly a light bulb came on. I grabbed some wrenches, took down the dish and held my cell phone next to the antenna’s horn. I was amazed to find that I instantly got full signal. I could not believe my eyes. I went from no signal to full signal and had not spent a dime or changed anything on my cell phone. Just to make sure I made a call using speaker phone and found that this thing truly did work.

The next test came when I took the assembly inside the house to try it. With aluminum siding on the house I have problems even getting a television signal using a rabbit ear antenna. To my surprise, I got two bars inside so long as I pointed the dish at a double window in my living room. I no longer miss calls and I don’t have to leave home to talk on my cell phone. It isn’t an ideal setup but it works and did not cost me anything. It is also a great way to recycle that old dish antenna that would have ended up in the trash otherwise.

I will try this myself, as I have the two main elements: weak cell signal and an old antenna.

 

 

 

Three Years Ago

Thursday, March 26th, 2009

Building online communities does not happen overnight. I started building one in October of 2002 for my fraternal group in Ukrainian Scouting. We used YahooGroups to help facilitate communication and information sharing. Pretty active little group, but closed to the public.

In mid-2005, while employed at SES AMERICOM in Princeton, our new CEO’s plan included starting a blog. I didn’t think we needed it, but with help from Mike Ford, I soon came around and became the chief blogger and promoter. I also had responsibilty for keeping our external Web sites current (SES AMERICOM, AGS, REDiSat Network, IP-PRIME, ABN and HD-PRIME), so I was the natural choice. What a great experience it was working with the team at EchoDitto, Joe Trippi and Matt Gross.

Here I am, still editing this blog but no longer employed by Americom. Since we went live in early March of 2006, this blog has logged more than 196,000 visits and 322,000 page views. Not bad for a B2B blog in the satcom business (so they tell me). Besides ILS (who I advised), nobody in our community has built a real blog. Now Intelsat seems to be coming around with their blog, introduced this week.

So far, the posts have been strictly business and one way in nature. Hope they stay active and find their voice online. And let’s see how long it takes for my comment to be published — if ever. 

Blogging is good for you. Go on.

Artel Moves Intelsat

Tuesday, March 24th, 2009

 

 

Way to get the business, Intelsat. Moving a spacecraft from the U.S. arc to the Indian Ocean Region:

Following an urgent call from the Pentagon’s Joint staff on February 6, Intelsat responded with a solution to reposition one of its domestic U.S. satellites, Galaxy 26, to a new orbital location in the Indian Ocean region. Intelsat began moving Galaxy 26 from its orbital slot at 93 W to its new position on February 20, once the existing commercial traffic assigned to the spacecraft had been shifted to another Intelsat satellite, Galaxy 25. Intelsat was able to begin drifting the Galaxy 26 satellite into its new orbital position only two weeks after the Department of Defense (DoD) request, a demonstration of how quickly the commercial industry can respond to solving critical warfighter requirements.
The contract, awarded through Artel Inc. as part of a DoD contract known as the DSTS-G (Defense Information Systems Network Satellite Transmission Services – Global), will fill a military bandwidth void supporting UAV surveillance operations. The repositioned Intelsat satellite will support launch and flight operations of Unmanned Aerial Vehicles (UAVs) deployed in the war zones, as well as other U.S. and NATO military operations in an area reaching from Germany to Southeast Asia.
"One of the key advantages of the Intelsat fleet is its scale and flexibility," said Kay Sears, President of Intelsat General. "This is the third time we have been able to reposition one of our satellites into a new orbital location to support critical operations on the ground in these two vital regions. Moving this satellite to the Indian Ocean region will prevent the disruption of a range of important military activities in that area."
The contract calls for up to 432 MHz of bandwidth using 12 Ku-band transponders operating on the Galaxy 26 satellite, which had most recently been serving North America. The satellite, using wide-beam capability, can support up to 40 UAV sorties simultaneously.
"This move is of particular importance, since we did not want any service interruptions to the DoD missions and there was no other capacity available to fulfill these requirements without this bold move by Intelsat," said Abbas Yazdani, President and CEO of ARTEL.
The demands for bandwidth created by the conflicts in Iraq and Afghanistan previously prompted Intelsat to twice move satellites in support of Intelsat General’s military customers.
Anything to keep the customer happy, but it helps to have a spare communications satellite to work with. 

The Satellite Game

Tuesday, March 24th, 2009

 

 

Access Intelligence still has a pretty good game going, with hundreds paying money to attend their show in Washington. It opens today.

I can hardly contain my excitement.

We Gonna Launch It

Sunday, March 22nd, 2009

 

 

Eutelsat is launching a spacecraft from China. That’s big news, via Telecommunications Online:

A recent decision to build a new rocket launch site in Hainan island and securing a deal to launch Europe-based Eutelsat Communications’ 5-ton satellite have put the spotlight on China’s space ambitions.

These developments testify to China’s success in pursuing space technology under its own steam following a U.S. policy in 1990 barring it from launching satellites with U.S. components. The impact has left China to seek customers from second-tier operators from Asia, Africa and South America.

The Eutelsat order is the first satellite launch deal from a major western country in more than a decade for China marking a high point in its space exploration and satellite-building program. As a supplier of commercial satellite products and services to the United States, Eutelsat’s order with China is seen as controversial by industry observers and officials on both sides have been cagey about confirming the order.

Made without any U.S. components, the Eutelsat satellite is scheduled for launch by China’s Long March rocket in 2010. Cost competitiveness is a good reason for China’s ability to secure the satellite launch order which could be as much as 40 percent less than the price of its western counterparts. The last launch of a western satellite on a Chinese rocket was in 1998 by ChinaStar for a Lockheed Martin-made satellite.

Based in Paris, Eutelsat carries quite a bit of U.S. Government traffic over the Middle East. They got bitch-slapped last month by California Congressman Dana Rohrabacher (R-CA):

During the House Committee on Science and Technology’s hearings on export reforms on Wednesday, California Congressman Dana Rohrabacher (R-CA) issued an attack on Eutelsat for its decision to launch its communications satellites on Chinese Long March rockets. This is something that is forbidden to American satellite owners under export laws.

Rohrabacher’s said:

“Everyone agrees ITAR reform needs to happen. We need to make sure that our hi tech exports aren’t strangled by regulations. On the other hand, we need to remain vigilant that our advanced technology doesn’t end up in the hands of nations who proliferate weapons of mass destruction. We know exactly who these nations are, and we must make absolutely sure that whatever changes we enact to ITAR and other export regulations, that these scofflaw and rogue nations are barred from receiving our high tech systems.

“Chief among them is the Peoples Republic of China. Ten years ago, the Cox Report clearly demonstrated that U.S. technology transfers to the Peoples Republic of China helped to improve and enhance the efficiency of China’s arsenal of missiles that were aimed at us. As a consequence, we passed the Strom Thurmond Act, which established the requirement that before any satellite technology could be exported to China, the President of the United States had to first certify to Congress that the tech transfer was not inimical to our national security or our domestic launch or satellite industries. Since the Strom Thurmond Act became law 10 years ago, not a single such certification has been made by any administration, and as a consequence no Western satellite payload has flown on a Chinese rocket.

“But the resolve of the Obama Administration is now being tested in this area. Just as our Secretary of State, Hillary Clinton was visiting the Peoples Republic of China, European satellite operator Eutelsat was a cutting a deal with Beijing for a launch on a Long March rocket. Incidentally, Eutelsat sells tens of millions of dollars worth of satellite services to the U.S. Government through DISA contracts. Clearly, this is the beginning of a game of chicken between Eutelsat and the Obama administration. If the Obama administration does nothing, the message is clear—transferring technology to proliferators of weapons of mass destruction like the Peoples Republic of China is a perfectly acceptable business model.

“Surely we can make sensible changes to ITAR and other export regulations, but we must not go so far as to make them at the expense of our national security. Let us reward our friends with openness in trade; and conversely let us be as single-minded as possible in stopping items from the United States Munitions List—like Eutelsat payloads– from falling into the hands of the Peoples Republic of China and other proliferators.

More fun with China.

DIY Friday: Solar Cell of Donuts and Tea

Friday, March 20th, 2009

Excellent use of resources: powdered donuts and tea, via Register Hardware:

In a fast-paced video, the presenter runs through a process that essentially combines chemicals from tea and American-style sugared doughnuts to form a solar energy soaking film that can be applied to a sheet of glass.

The process isn’t easy and requires a fair amount of scientific kit, but he starts by extracting “titanium dioxide nanoparticles” from some powdered sugar doughnuts.

Roughly ten layers of these nanoparticles applied to a sheet of glass is, according to the video’s presenter, “pretty much a solar cell”.

But because this set-up on its own won’t work with “regular sunlight", the presenter next extracts organic dyes from a cup of sweet tea that enables the solar cell to “absorb light we can see”.

Finally, to prove that his invention works, the solar scientist hooks the cell up to a multimeter that appears to show an electrical current being generated from the DIY solar cell. 

Donuts. Is there anything they can’t do?
