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.

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.
