Colonizing space will require a lot of stuff, iron to build space stations, titanium to build spaceships, oxygen for us to breathe, and many other resources. Lifting all this up from the surface of the earth on rockets is simply not feasible. Thus, we will need to find these resources somewhere else. You need look no further than the moon. It has all the natural resources we need to colonize space but the question remains, how do we get them into orbit? Even on the moon, rockets are not feasible, but something else might be.

An idea emerged over a century ago called a mass driver. The first mass driver described in print was in the 1897 science fiction novel A Trip to Venus by John Munro. He called it an electric gun. It was his imaginative method of launching vehicles into outer space from the Earth’s surface. Munro describes the electric gun as a series of coils energized in a timed sequence to provide the force necessary to get the spaceship into orbit.

Your Very Own Personal Space Program

Michael Mackowski, a member of the Phoenix chapter of the National Space Society, has given us another interesting essay:

Your Very Own Personal Space Program

There are many ways folks express their interest in the space program. Some space enthusiasts read everything they can find and often have a large book collection. Some people accumulate souvenirs and autographs. Photos, patches, and pins are popular collectibles. Scale models can be another way to bring the space program to life in your home or office.

I have been inspired by space exploration since I was a youngster. Prior to finishing school and entering a career in aerospace engineering, my participation in the space program was limited to building scale models of the vehicles that were leaving the planet. Actually, I have never stopped building models of spacecraft, even while I build them for a living as an engineer. Like engineering, I find that modeling is just another expression of one’s creativity.

Over the years I have been participating in a network of other hobbyists with similar interests. What I have found is that many of these people, while being hobbyists and craftsmen in terms of their model building, are also passionate about space. My situation is a bit unique in that space is both my hobby and career. Most people who are passionate about space have other, usually non-technical careers. So one way they can feel closer to space exploration is by building small replicas of the hardware that makes it possible.

Certainly this sort of passion is the root of many hobbies. Military history buffs build models of tanks and fighter jets. Auto racing enthusiasts build race car models. Would be sailors rig up miniature ships and sailboats. People collect or paint miniature horses because they cannot afford to own a real horse. Airplane fans who cannot afford lessons or a plane can have a shelf full of models. Frustrated astronaut candidates build Apollo lunar modules and space shuttles. It’s not the same, but for many people it may be as close as you will get. It’s your own personal space program.

Enthusiasts want a piece of the space program they can see up close, hold in their hand, and relate to three dimensionally. Books and videos and internet sites are flat and virtual. A model is real and fills space. And you built it yourself. That’s why model building is more fulfilling than just collecting or buying pre-built souvenir models. You are now a rocket scientist, only scaled down, and with simpler technology. You have combined art with technology. You feel more a part of the movement, a part of the collective that is moving out to space. Through model building, you are more than an observer. You have made a statement, that by building this miniature monument to space exploration, you are supporting it, and proclaiming it to whomever enters your hobby room or office or wherever you chose to display your work.

If you can’t be an astronaut or be an engineer in the space industry, you can have your own little private miniature space program, and thus pay homage to whatever past or future off-planet venture that inspires you.

In that way, maybe it will inspire someone else, and the movement grows by one more.

The Vegetable Garden on the International Space Station

The latest crop harvested from the Garden on the International Space Station is Mizuna lettuce. The lettuce was returned to Earth for scientific research, aboard the Discovery shuttle in April 2010.

The greenhouse, first sent up in 2002, has been used for 20 plant growth experiments so far. Now, a second unit has been added, and the lettuce crop was the first experiment to test different conditions side by side.

For many years, the experiments have sought to confirm Earth side results which show that minimizing water usage and salt accumulation would lead to healthier crops. During this experiment, two different root growth mediums were used. One was the traditional root pack used on all the previous tests. The second was the new and improved root pack, with slow release fertilizer. The hypothesis was that the slow release would help reduce salt intake.

Science is sometimes best when things go wrong.

For some reason, the sensor controlling the watering in the first (traditional) module failed. This resulted in “over-watering” the plants. The results were surprising, but microgravity has held many surprises for scientists. First, the seeds that got “too much” water sprouted quicker and developed leaves twice as fast as the second (improved) module. The second surprise was that the plants grown in the slow release fertilizer in the second module had more salt accumulation than the plants in the first module.

The results suggest that plants in space need a larger volume of water and a faster rate of fertilizer than they do under normal gravity. Shane Topham, an engineer with Space Dynamics Laboratory at Utah State University in Logan, said that “the conservative water level we have been using for all our previous experiments may be below optimal for plant growth in microgravity”.

Overall, the garden experiments have four objectives:

  • Can the crops grown in space be consumed safely
  • What microorganisms grow on the plants, and how do you prevent or minimize microorganisms in the modules prior to launch
  • How do you clean and sanitize the crops after they are harvested
  • What conditions optimize the production of crops in microgravity

One additional objective of the experiments is to measure the non-nutritional benefits (stress relief, etc.) that crew members experience working with plants in space. Growing and tending to the crops provides comfort and relaxation to the crew. On a long voyage, this activity may contribute to the success of the mission.

Astronauts4Hire wants to create the first pool of private astronauts to support the emerging suborbital research industry.

A commercial spaceflight revolution is underway. Within a few years, private companies will provide routine access to space. Besides wealthy tourists, scientists are among those poised to benefit since they can use the new spacecraft as platforms to perform research in microgravity. The demand for skilled commercial scientist-astronauts to aid in this new industry is growing rapidly. Astronauts4Hire wants to create the first pool of private astronauts to fill this need. In doing so, we hope to demonstrate that space is accessible by anyone and inspire the next generation to pursue careers in space.

The countdown for the GOES-P Geostationary Operational Environmental Satellite aboard the Delta IV is at T-minus 30 minutes at 3:33 PM Phoenix time prior to a built in hold.

You can follow along with the launch on NASA-TV.

Patrick Air Force Base has published their Launch Hazard Area warning for the Delta IV launch. We note the $250,000 fine for violating the space.

Weather briefing at 3:40 PM indicates clear skies, winds from 10 to 15 knots at the launch site and no upper atmosphere conditions that would cancel the launch.

GOES-P is the third in the current series of GOES satellites (GOES N-O-P) and will be commissioned as GOES-15 once in its geostationary orbit. Its designed lifetime is seven years, with fuel for as much as ten years if the lifetime is exceeded. The next generation will be the GOES-R series, scheduled for deployment beginning in 2014.

We are currently at T-minus 10 minutes at 3:53 PM Phoenix time prior to the built in 15 minute hold at T-minus 5 minutes.

At 3:58 PM, the launch director has announced the hold at T-minus 5 minutes. Systems are checking off items required for internal power. Weather has reported that upper levels winds are green for the first ten minutes of the launch window.

L-minus 15 minutes. Launch weight is 733,000 pounds. Total LOX is 45,500 gallons and total LH2 is 120,000 gallons. The GOES-P satellite weighs 7,005 pounds.

Final poll of all systems, prior to resuming the count, will occur at L-minus 10 minutes (4:08 PM Phoenix time).

There are three items not ready, and one red alarm being evaluated, The poll has been suspended. The launch count will not resume until these have been cleared. There is currently no estimate on resumption of the countdown.

Weather now reports upper level winds are red, and the earliest resumption of the launch countdown would be 4:42 PM Phoenix time with launch at 4:47 PM.

Now that the Saints have won the Super Bowl, we can get back to the important events that affect the real world.

At the moment we are in a built in hold at T-minus 3 Hours. Weather is looking very good. The Air Force 45th Weather Office is optimistic.

At 9:57 PM Phoenix time (11:57 PM EST) we have about 25 minutes left in this built in hold.

The current satellite weather map looks very favorable. There is only a thin band of clouds approaching Florida and the Cape that may affect the launch.

Weather is currently at 60% for a launch.

At 10:00 PM Phoenix time, there are no technical issues being worked prior to launch at 2:14 AM Phoenix time. Weather is expected to be favorable for launch on time. There are about 20 minutes remaining in this hold.

We will resume live blog about 30 minutes prior to launch.
