Space Cadets, All Hail The Dragon!


The gringa wants to introduce you to the Dragon. This automated spacecraft, designed by SpacEx, is the first commercial spacecraft EVER to deliver cargo to the International Space Station and return cargo to Earth. Governments can move over because private industry has got this job covered. Refinements are underway so that very soon the Dragon will be able to achieve the ultimate goal it was designed for, to carry a human crew.

The configurations of the Dragon are versatile. It can be used, as it already successfully has shown, to be a perfect cargo vessel. It will very soon have the capability to house a human crew. However, it’s not your average space taxi. It can also be used as a DragonLab to conduct technology demonstrations and scientific experiments in outer space. The different configurations are so similar, that converting from one to another is relatively quick and seamless.

The Dragon’s pressurized section houses the cargo and crew. The outside base of this section carries the thrusters, guidance and navigation control bay as well as the ever critical heat shield. The Dragon even has a trunk. No, it’s not where the astronauts store a spare thruster and crowbar. This is the part of the spaceship that is the foundational support during ascent, houses the craft’s solar arrays, and can also carry cargo that does not need to be pressurized. Just before the Dragon enters the atmosphere of Earth, this section is jettisoned. The gringa thinks, “How many of us ladies wishes it was so easy to get rid of unwanted junk in our trunk?”

Presently, the primary mission of the Dragon is to routinely resupply the International Space Station. This is not your average delivery-man job. I don’t believe UPS or FedEx train their delivery personnel for the effects of anti-gravity. To accommodate these effects, the cargo hold is filled with honeycomb shaped racks constructed of a carbon-aluminum material.

After the first successful test flight in 2012, and many more resupply missions after that, the Dragon has been undergoing upgrades. Hopefully, very soon, perhaps within the coming months, NASA crews will perform the first manned test flight in a vessel that SpacEx says will be the world’s safest crew transport spacecraft. It will seat seven. The gringa doesn’t take up much room. For being so tiny I’m also awfully strong. I would make a perfect space delivery person. I’d be so happy to be a part of something this fantastic, I wouldn’t even expect the astronauts to tip me.

A Bit Of Sun & Hope For Humanity


Coming up in December is the one year anniversary of the test flight of the Orion spacecraft that launched from Kennedy Space Center December 5, 2014. The test flight was unmanned. Because of its success, the next time Orion punches through the Earth’s atmosphere, it will deliver astronauts to an asteroid in our Moon’s orbit to rehearse their Red Planet mission. That is the ultimate goal, after all, to have a full astronaut crew heading out to deep space with a final destination of Mars.

The amazing new technologies that will send astronauts farther than they have ever gone before is thanks, in part, to the students of science, technology, engineering and mathematics (STEM). NASA and Lockheed Martin offered students the opportunity to collaborate in this daring mission with a program called “Exploration Design Challenge”. What problem were these students asked to solve? The students were challenged to solve the most dangerous issue that faces humans in space – exposure to radiation. The gringa is very proud to say that these students rose to the challenge and their very own radiation experiment was on board for Orion’s test flight. If there was ever a reason for parents to encourage their children in STEM curriculum, parents, the time is NOW!

The emerging generation of scientists will inherit a planet that is rapidly changing. NASA needs this young talent more than ever. Researchers will manage the data collected from satellites and airborne missions. Engineers will keep these missions alive with their technological expertise. These are the critical thinkers the world needs to face the future challenges of rising sea levels and extreme weather events due to climate change. The next generation of astronaut explorers will be the ones to aid our planet in finding freshwater resources out in the cosmos to help replenish are own that are rapidly becoming depleted.

In 2014 NASA studies were published and revealed a rapidly melting western sheet of ice in Antarctica. This appears to be irreversible. Later in the same year, NASA, along with researchers at the University of California, Irvine, concluded that the potential threat of groundwater loss to America’s stable water supply may have previously been underestimated and things were worse than scientists thought. In August of 2014, NASA published research based on the discovery of a large amount of a compound creating ozone depletion. This was an unexpected surprise considering that for decades such a compound has been banned worldwide. Our world is in trouble and our best resource to solve these problems is in the minds of our youth.

The gringa is getting depressed with all this bad news so, let’s get back to the good news! The Orion! I simply must know all I can about this spaceship because the gringa is putting in that ship all her hopes that it is going to be the mother ship of a future fleet of ships that’s going to save humanity’s bacon.

The purpose of the test flight was to see if Orion was up to the task of the most dangerous parts of the mission. Those would be lift-off, entry, separations, the jettison of the Launch Abort System, descent and splashdown. However, most important of all was to test the heat shield that needed to be strong enough to protect astronauts, as well as all the technology on board, from 4,000 degree Fahrenheit temperatures and the related radiation. Is the dear reader dying to know Orion’s report card? The gringa is!

At 7:05am at Cape Canaveral Air Force Station in Florida, Orion was prepped to lift off with the help of a United Launch Alliance Delta IV Heavy rocket. Three RS-68 engines created almost two million pounds of thrust which then pushed a 1.63 million pound spacecraft into orbit. After about four minutes the side boosters disengaged and fell away to Earth. The center booster remained with Orion for another ninety seconds. When its fuel was spent, it disengaged and also fell back to Earth. The next thing to release its hold on Orion was the structural supports and the Launch Abort System. Orion was headed out of Earth’s atmosphere.

Seventeen minutes and thirty-nine seconds after lift-off, Orion began its orbit. Two hours into its flight, Orion traveled through the Van Allen radiation belts which are 3,609 miles away. Data recorders provided critical calculations on the doses of radiation within the cabin. This determined if the craft was of sound design and safe to man with a human crew. Three hours and twenty-three minutes into its flight, Orion headed for Earth’s atmosphere where the heat shield withstood the brutal re-entry friction.

What is re-entry like? Orion hit Earth’s atmosphere at a speed of 20,000 mph. The gringa can only say, “Incredible!” The spacecraft gets so amazingly hot at that speed, it is eventually enveloped in plasma. Plasma is considered the fourth state of matter after solids, liquids and gases. When plasma is created on Orion upon re-entry, what happens is that the heat and friction become so energized that electrons break free from their nucleus and travel along with them. That’s what the Sun does all the time. It’s just a big, ol’ ball of plasma. Orion creates a little bit of Sun on re-entry. The gringa’s mind is filled with the Beatles refrain, “Here comes the sun, little darlin’. Here comes the sun. And I say it’s alright.” After all, ultimately that IS the plan, RIGHT? Orion is going to help launch the scientific efforts that hopefully will make everything wrong with the environment alright? Or, at least give humanity some viable options and hope?

After picking up Orion as it bobbed amongst the waves of the Pacific of the coast of Baja, California, NASA used the data to make improvements for the upcoming manned mission. Astronauts will continue their own preparations for a mission that is sure to make history in so many ways. If everyone at NASA is excited about the future, then they truly believe in the mission. The gringa will take her cue from them and toss out the doom and gloom and grab hold of hope and positivity. I will hold fast to an exciting future that most certainly is full of change, but change is not necessarily always a bad thing.

All Aboard The “Moon Express”


A couple of years ago “Moon Express” completed a round of flight tests at Kennedy Space Center. Evidently, this didn’t seem like big news because the popular media sources were rather silent on the matter. Is the “Moon Express” newsworthy or not? The gringa just had to find out. I mean, with the name “Moon Express” conjuring up images in my mind’s eye of a space alien whodunit novel, surely there’s a story in there somewhere.

The “Moon Express” is a private company partnering with NASA’s Lunar CATALYST mission to provide a chunk of technology referred to as “MX-1”. The primary role of Moon Express is in the field of transporting commercial cargo from the Earth to the Moon. The MX-1 is an innovative lunar landing vehicle to help Moon Express fulfill its self-proclaimed mission of “blazing a trail to the Moon to unlock its mysteries and resources for the benefit of life on Earth and our future in space.” Considered by Moon Express to be the eighth continent, the company, with NASA’s support, looks to the Moon as an economic opportunity in order to exploit its natural resources that are rare here on Earth. What are these natural resources and their potential to help mankind?

Take, for instance, the platinum group metals classified as PT-78. Platinum is so scarce on Earth, that humans are only capable of producing a few hundred tons every year. This metal is the least reactive and most resistant to corrosion and can withstand extremely high temperatures. Platinum is most commonly used as a catalyst to produce chemical reactions such as igniting hydrogen and is used in the catalytic converters of automobiles. Estimates of manufacturing experts claim that almost one fifth of industrial applications require platinum. The plan is to mine this valuable commodity found on the Moon, return and sell it back on Earth, and the fellas at Moon Express can make the bank and fund their goals of further space exploration. Is that not the wildest “American Dream” story ever? The gringa is fascinated. I’m thinking of going out and buying a pick-axe and shovel and wheelbarrow and coveralls and…

And, the first stage in achieving these goals is the MX-1commercial lunar lander. This robotic spacecraft will deliver scientific and commercial cargo much cheaper than NASA. How can they do this? Moon Express has developed a “green” space vehicle that is powered by sunlight and, for fuel, uses hydrogen peroxide! Next time the gringa cuts herself, when cleaning the wound and the hydrogen peroxide gets all fizzy, I will imagine myself blasting into space like a shooting star!

Moon Express is just one of a small handful of private companies that have contracted with NASA. These contracts do not allow any funds to be exchanged. They are, rather, an agreement about support services and technologies that will be shared. Moon Express in particular will play a key role in assisting space exploration objectives such as returning geologic samples from the moon, providing the first platform of deployment for further space exploration, and prospecting resources on the Moon such as metals, water and oxygen that can be used to advance space exploration programs.
