A Midnight Post From my Desk. It is Good to Be Back.

Hello Troops,
The disturbance in the Force has been corrected.  After several weeks of sleeping in the gym, the boys on tonight's Overnight Camp are sleeping in the ship.  There are more boys than girls, and everyone knows that the larger of the two groups always sleeps in the Voyager.

I have access to my desk and a fairly quiet room surrounding me.  The gym is louder with every noise amplified by the volume of the room.  I still have to content with what I think are the brightest EXIT signs in in the free world and air conditioners made for rooms twice the size of my classroom (I think the District purchased them used from NASA's wind tunnels at Moffit Field, California).  The best thing is knowing that I won't be woken up in the middle of the night by a collapsing cot caused by a careless boy who wasn't listening to my 'How To Get Into a Space Center Cot' demonstration given before lights out. 

"Attention, Attention.  Stand by for a demonstration on the proper procedure for entering and exiting a Space Center Cot."  The boys give me that 'are you serious' look.  I continue.  "To enter a cot one first finds the exact center of the cot.  I suggest you look for the center set of legs.  Once the exact center is found, one sits down carefully, not wanting to rock the cot too much.  Think of getting in and out of an unstable row boat. Once seated, you may then turn 90 degrees and stretch out.  Use the same procedure when exiting a cot.  Your cot will not collapse in these procedures are followed exactly."

When I'm sleeping in front of my desk the only thing I listen for are sleepwalking boys who open one of the emergency exits in a bid for freedom from whatever haunts their sleep.  Oh, there is also the thing I listen for, a boy tumbling from the top tier of our 3 level bunk beds.  The fall can be nasty and painful if one measures true pain by the amount of weeping and wailing produced by the injured camper. 

Jon Parker just disturbed my solitude and wistful enjoyment of sitting at my desk as the clock struck midnight.

"This broke off the Voyager Right Wing desk," he said while holding up a long section of the blue trim surrounding the Voyager's desk top.  I wondered if this was his calculated attempt at ruining my night.  I'm tired, its late and I've much to write and even more to do.  I wanted to take the long blue shard and play out a scene I affectionately call 'Victor, the Vampire Slayer' where killing the messenger is common fare.

My brain went into work mode.  I thought of the time it would take to have the District's wood shop make a new desk top.  My calculations indicated there was at least a 90% chance I wouldn't live long enough to see the repair completed to my satisfaction.  I handed Jon a roll of clear plastic packing tape and a pair of scissors.

"Do the best you can," I ordered. I asked him to document the midnight repair for a special PBS documentary on 'The Insane and How They Hide Among Us."

 The Damaged Desk.  You can see the large shard missing from the bottom of the blue trim.

Jon is holding the shard into place while he peels off a section of packing tape and applies it using an elbow as a brace. 

    

Jon's adds a few finishing touches before calling the repair compete.

I'll have all our inquisitive Troubadour readers know how proud we are of the fact that many sections of our simulators are held together with tape, wire and generous amounts of prayer fussed over by our more religiously inclined staff and volunteers.  You'll never know where the repairs are unless you look long and hard.  We have a policy to counter snoops like that.  We go to red alert, switch to red lights and release the dreaded Slime Devil.  Moments later, the snooping child is showered with Slime Devil venom from our Enola Gay Atomic Action Water Blaster.  Down to Sick Bay he goes for a lengthy recovery.  A recovery not even a generous amount of M&M's can shorten. 

Well, its time for bed.  I'm tired and ready for some down time with my pad, pillows and blankets waiting for me on the floor in front of my desk!

Could the Enterprise Be Built Today?

 

By Nancy Atkinson

Universe Today

In Star Trek lore, the first Starship Enterprise will be built by the year 2245. But today, an engineer has proposed — and outlined in meticulous detail — building a full-sized, ion-powered version of the Enterprise complete with 1G of gravity on board, and says it could be done with current technology, within 20 years.

"We have the technological reach to build the first generation of the spaceship known as the USS Enterprise — so let's do it," writes the curator of the Build The Enterprise website, who goes by the name of BTE Dan.

This "Gen1" Enterprise could get to Mars in 90 days, to the moon in three, and "could hop from planet to planet dropping off robotic probes of all sorts en masse — rovers, special-built planes and satellites,” BTE Dan says.

Complete with conceptual designs, ship specs, a funding schedule and almost every other imaginable detail, the BTE website was launched just this week and covers almost every aspect of how the project could be done. This Enterprise would be built entirely in space, have a rotating gravity section inside of the saucer, and be similar in size with the same look as the USS Enterprise that we know from classic "Star Trek."

“It ends up that this ship configuration is quite functional,” writes BTE Dan, even though his design moves a few parts around for better performance with today’s technology. This version of the Enterprise would be three things in one: a spaceship, a space station and a spaceport. A thousand people can be on board at once — either as crew members or as adventurous visitors.

While the ship will not travel at warp speed, with an ion propulsion engine powered by a 1.5GW nuclear reactor, it can travel at a constant acceleration so that the ship can easily get to key points of interest in our solar system. Three additional nuclear reactors would create all of the electricity needed for operation of the ship.

The saucer section would be a 0.3-mile-diameter (536-meter-diameter) rotating, magnetically suspended gravity wheel that would create 1G of gravity.

The first assignments for the Enterprise would have the ship serving as a space station and spaceport, but then go on to missions to the moon, Mars, Venus, various asteroids and even Europa, where the ship's laser would be used not for combat but for cutting through the moon's icy crust to enable a probe to descend to the ocean below.

Of course, like all spaceships today, the big "if" for such an effort would be getting Congress to provide NASA the funding to do a huge 20-year project. But BTE Dan has that all worked out, and between tax increases and spreading out budget cuts to areas like defense, health and human services, housing and urban development, education and energy, the cuts to areas of discretionary spending are not large, and the tax increases could be small.

"These changes to spending and taxes will not sink the republic," says the website. "In fact, these will barely be noticed. It’s amazing that a program as fantastic as the building a fleet of USS Enterprise spaceships can be done with so little impact."

BTE Dan adds that "the only obstacles to us doing it are the limitations we place on our collective imagination." His proposal says that NASA could still receive funding for the science, astronomy and robotic missions it currently undertakes.
But he proposes not just one Enterprise-class ship, but multiple ships, one of which can be built every 33 years — once per generation — giving three new ships per century. "Each will be more advanced than the prior one. Older ships can be continually upgraded over several generations until they are eventually decommissioned."

BTE Dan, who did not respond to emails, lists himself as a systems engineer and electrical engineer who has worked at a Fortune 500 company for the past 30 years.

The website includes a blog, a forum and a Q&A section, where BTE Dan answers the question, "What if someone can prove that building the Gen1 Enterprise is beyond our technological reach?"
Answer: "If someone can convince me that it is not technically possible (ignoring political and funding issues), then I will state on the BuildTheEnterprise site that I have been found to be wrong. In that case, building the first Enterprise will have to wait for, say, another half century. But I don’t think that anyone will be able to convince me it can’t be done. My position is that we can — and should — immediately start working on it.”

Going Back to Space: ATK 's Liberty rocket

ATK's Liberty rocket and capsule program.

With the end of the shuttle and the Space Transportation System (STS), it seemed to some outsiders that ATK would no longer have a market for those large 4-segment Solid Rocket Boosters (SRB's) that propelled the shuttle orbiters into space. Also not boding well for the company was the cancellation of the Constellation program and the Ares rocket system after only one test of the Ares 1-X. But you can't keep a good team down. ATK has bounced back as a major competitor in the CCD race to space.

Comparing the commercial rockets under development or already available. "A" is the SpaceX Falcon Heavy, still under development. "B" is the Liberty rocket.

ATK has joined forces with key companies to put together the Liberty commercial crew transportation system. With ATK providing a 5-segment SRB first stage, the makers of the Arianne rocket, Astrium, providing the liquid-fueled second stage, and now Lockheed Martin providing support for ATK's Liberty capsule, all the components are together.

Because much of the hardware of the rocket is already tested and flown, it remains to ATK to assemble the package and flight test it and attain a human-rated approval. The toughest part of the process will be quickly developing a crew capsule. And ATK has that in hand, as well. Between 2007 and 2010, ATK had built a composite-structure capsule for a NASA program to reduce risk in transporting humans to space. Now ATK will modify the capsule to fully comply with safety and engineering requirements.

ATK also has the most ambitious schedule of the companies racing to provide commercial crew service. According to their plans, the first unmanned mission will launch in 2014, with the first crewed spaceflight in 2015. This would place ATK a year ahead of SpaceX Dragonrider, and several years ahead of NASA's SLS/Orion system.

5-segment SRB first stage testing in Utah.

ATK is finishing testing of the SRB first stage in the Utah test facility. They are also working on the launch abort system that could save the crew capsule in an emergency on the pad or during launch. As you can see from the picture below, progress is moving at a rapid pace on the Liberty capsule.

Engineers preparing the composite-structure spacecraft.

Barring any unforeseen difficulties in testing, my money would be on ATK to be fairly close to its schedule projections. The project is led by former astronaut Kent Rominger and the ATK team is experienced in building space technology systems. Keep an eye out for more news from ATK as their systems get ready for launch.

Going Back to Space: SpaceX Makes History

The Falcon 9 rocket with Dragon cargo spacecraft.

Space Exploration Technologies, or SpaceX, builds the Falcon 9 rocket and the Dragon cargo spacecraft. They are the first among the private companies to build and launch an orbiting spacecraft. It could be said that Boeing, Lockheed, and other companies were first to build the Mercury, Gemini, Apollo and Shuttles but those who totally government operations. On December 9, 2010, SpaceX became the first privately funded company to launch, orbit, and recover their spacecraft.

SpaceX launch facility at Cape Canaveral.

Launched from LC-40 (from which NASA had launched all the Titan-3 and Titan-4 rockets from 1965 to 2005), the Falcon 9 rocket successfully placed the Dragon test spacecraft into an orbit 179 miles high. The Dragon made two successful orbits and then re-entered the atmosphere for a splashdown in the Pacific Ocean, being recovered within 20 minutes of touchdown.

COTS Demo Flight 1 blasts off.

The flight fulfilled many of the milestones required by the NASA Commercial Orbital Transportation Services contract (COTS). Additionally, after the Dragon spacecraft separated, the second stage was reignited and moved to a higher orbit of 6,800 miles, proving the system could reach higher orbits. SpaceX now prepares for further milestones in the contract with NASA.

Dragon perched on the Flacon 9, on pad LC-40 right now.

SpaceX plans to accomplish a major feat this weekend. In the early hours of Saturday morning, another Falcon-9 rocket will lift off with another Dragon capsule. This time, the capsule is full of supplies for the International Space Station. This mission is expected to fulfil the COTS demo fllights 2 and 3 together. The Dragon spacecraft will be guided to make a near pass of the ISS, and on a subsequent orbit, to approach the ISS within reach of the station's robotic arms. Astronauts of Expedition 30 will use the arms to grapple the Dragon and dock it to one of the hatches.

We're all fingers crossed hoping the best for this mission. Should everything go well, SpaceX will be well on its way to providing regular cargo servicing of the ISS. There's an additional bonus for NASA to use the Dragon: It is the only cargo spacecraft capable of returning items from the ISS to the Earth. Both the ATV of Europe and the Progress of Russia routinely burn up in a re-entry.

SpaceX is not stopping with cargo delivery. They are well on their way to launching humans to space. Company founder Elon Musk has a vision to take his rockets all the way to Mars, eventually. To get moving on that path, the company's engineers are designing the Falcon-Heavy, which will be capable of lifting much larger payloads into orbit and beyond. More significantly, SpaceX is building a human-rated version of the Dragon capsule.

Inside DragonRider.

The crewed variant of the Dragon capsule will be called the DragonRider. As you can see in the picture above, it can hold up to 7 astronauts or a combination of personnel and cargo. SpaceX is currently building the first test capsules under the CCD program, which we talked about in an earlier blog. The company is also testing a launch abort system, and expects to fly the DragonRider by 2016.

Going Back to Space: Riding with Russians

Russian Soyuz TMA-04M mission blasts off.

On Monday night the Russian Baikonur Cosmodrome reverberated with the roar of the Soyuz rocket blasting off to the ISS. On board mission TMA-04M was the second part of the Expedition 31 crew: Russian cosmonauts Gennady Padalka and Sergei Revin, with NASA astronaut Joe Acaba. The liftoff was performed successfully and the Soyuz capsule is now in orbit on course for docking with the International Space Station on Thursday.

With the end of the Space Transportation System (STS) or Shuttle program, NASA relies on the Russian space agency to transport our astronauts back and forth from the ISS. With America's further reliance on the venerable Soyuz rocket system, the Russian government and space agency are seeking greater control over the ISS and the activities there. In addition, the Russians did not fail to grasp at a business opportunity: the cost of a seat on the Soyuz for the Americans jumped by at least 40%.

Astronaut Joe Acaba rides the Soyuz to low Earth orbit.

The Soyuz rocket has been a staple of the Russian space program for several decades. With its first unmanned flight in 1966, both the Soyuz spacecraft and the Soyuz rocket have become an icon of the Russian space effort. Like the shuttle, it has not been without its failures. The first cosmonaut on Soyuz 1, and the three-man crew of Soyuz 11, died during re-entry accidents. However, with the vast number of Soyuz flights succeeding, the Soyuz has become the safest space transportation system. It is also one of the most cost-effective. Because it has been built so many times, the cost has been managed to low levels, an achievement admired by many Americans.

Soyuz TMA-06 in orbit.

Russia currently flies a three-person crew on the Soyuz, and astronauts and other nation cosmonauts must train at the Russian space agency and learn the Russian language to participate in flights. An additional Soyuz spacecraft is kept at the ISS as an emergency escape craft. Russia has also built a cargo version of the capsule. The unmanned cargo version is called the Progress, the manned versions are the current TMA designation. This current manned version was revised from the earlier TM version when it was realized that taller astronauts would need extra room on the Soyuz. The TMA version has been flying since 2003.

Progress M-52, unmanned cargo version. Once supplies are emptied from the Progress aboard the ISS, space station garbage and unwanted equipment is stored aboard. When it undocks, ground controllers guide it to a fiery re-entry, burning it up over an ocean.

Over the last couple of years there have been some anxious moments between NASA and Russia as there have been some glitches and landing difficulties with the Soyuz spacecraft and other Russian rockets. While those problems are fixed, many Americans feel the Soyuz system is old. Even the Russians must be feeling the age of the design, as they have proposed a new design called the Prospective Piloted Transport System, which will carry up to six occupants.

Overall though, NASA is resigned to carry on our human space program at present by using whatever ride the Russians can provide. Right now there is no alternative. And perhaps that's what bugs Americans the most. With proper planning, we should have had a replacement by now.
