Travel To Mars & Manic Cats


When the caveman and I head south for an Amazon jungle escape in his homeland of Peru, we first have to endure a six hour flight from Houston. Since we are not made of money, we do not fly first class. And so far, I have yet to find an airline with a cuddle section in coach. Also, because of the horrible pollution in Peru’s capital, Lima, it’s location along the Pacific coastline and it’s coastal desert climate, there are only certain times of day that are suitable for flights because of smog and fog. The airport is active at night. So, getting there is not so bad. We can leave at a decent hour in the afternoon and arrive sometime after dinner. However, I have never been able to find any other flight back to the states that is not scheduled in the red-eye hours. This makes homeward air travel a grouch inducing event.

The gringa’s return trip experience usually goes something like this:

  • 10pm – Arrive at the airport
  • 12am – Settle into my airplane seat
  • 12:30am – Take off and read until I’m sleepy
  • 1:30am – Attempt to go to sleep which involves my travel neck pillow hanging in front to avoid the forward head bob which usually never really works so eventually I dig out a scarf and tie my head to the headrest
  • 2am – After tying my head to the headrest, I now have to pee after all the bending and twisting has tortured my bladder.
  • 2:15am – Re-tie my head to the headrest after returning from the bathroom. Discover I am wide awake. Untie my head and begin to read.
  • 3am – Tie my head to the headrest and try to sleep which involves fits and spurts of dozing off then those little jumps a body makes as you merge into deep REMs, wake up frightfully scared then embarrassed, need to pee again, blah, blah, blah.
  • 5am – Flight attendants come around with breakfast and I give up completely on sleep since now there is food involved.
  • 6am – Arrive in Houston where I am an absolute grouch until I collapse in my bed when I get home.

And that’s a “good” trip. One time we went and the air conditioner vent, those little circular doo-hickies up where the reading lights are that can pivot around? Well, the passenger in front of me had his on full blast and every now and then it would start spitting ice out and the angle was perfect for me getting shot in the eye about every thirty minutes or so. Just long enough for me to let my guard down, thinking that the other time it happened was just a fluke, then, “BAM”, right in the eye again. Oh, boy, I tell ya the gringa was spitting mad.

Then there was the time these three brothers were traveling together and they were all drunk as skunks. They wouldn’t stay in their seats. They would stand up, arms around each other, sing songs in Spanish, sometimes Portuguese, then hug and cry. I don’t know what they were singing about, maybe about their women that left them because they were loud and obnoxious drunks, but, eventually, one of them got sick right in front of the poor lady that was seated by the emergency exit. You how those seats that have all that extra space in front of them in the middle of the cabin? Yeah, he walked right over there and heaved. Then the lady screamed, jumped up, stepped in it, got so upset, tried to yell, gagged, then she puked. The flight attendant’s solution? Scatter a bucket of coffee grounds over it. Yeah, good times.

Which brings the gringa to the hopeful news out of NASA. I’m talking about their groundbreaking laser propulsion system. They are claiming that if the technology works, eventually crews could reach Mars in a matter of days. I’m guessing if that technology was put to use to get me to Peru a trip would be about as fast as Star Trek’s transporter technology. That sounds sensational to the gringa. No more dodging ice pellets or dealing with drunks or tying my head to the headrest and arriving home grumpy as a mad, wet cat.

So how does this laser propulsion business work? Scientists have known for some time how to propel objects at light speed. The reason this is not done with current spacecraft is because they are too heavy. Their weight creates all kinds of complications. Laser propulsion takes liquid fuel cargo out of the picture which drastically reduces the weight making light speed, then, a possibility, or at least a quarter of light speed a possibility. At that rate, a spacecraft could reach Alpha Centauri within 15 years. That’s a star about four light years away.

With that in mind, then, a spacecraft that weighs about 100 kilograms/220 pounds could reach Mars in about six months, give or take a couple of months either way. So, to get serious about space travel, we’ve got to speed up transit time.

The laser propulsion system is called “photonic” propulsion, but laser just seems a word most people immediately can visualize. When I think of laser propulsion, I envision spacecraft zipping through the skies like a flash of light and all the cats on Earth will end up with manic disorders. Many will injure themselves attempting to launch through windows at the laser light displays crisscrossing the skies. There may be troubling and dangerous times ahead for cats and cat lovers. But, heads up to the gringa’s more innovative readers. This could lead to a niche market in cat care products for kitties that are suffering from spacecraft laser related mania.

But, I digress, to get back to how it all works… rather than one giant laser shooting a spacecraft off into the heavens, multiple lasers would propel an aircraft. Multiple amplifiers would then combine the power of the individual laser to create a singular beam powerful enough to propel the craft. And, guess what… the technology already exists! Scientists and researchers only need to develop and test the technology with actual aircraft and spaceships.

Scientists and engineers are very excited because they know this idea will work. They have small amplifiers that are about the size of a school book. What they really want is an array of amplifiers floating in orbit around Earth in a six-square-mile configuration. That’s what it would take to shoot a black-eyed pea to Alpha Centauri. Um, the gringa’s going to need a little more room than that on a trip to Mars. I’m just sayin’, ya know.

Although the necessary scope of how large an array really needs to be sounds absolutely outrageous, like, perhaps an array covering hundreds of square miles and orbiting the earth, scientists still believe it is do-able. And yet, with all of this good news, there is one little problem the scientists save to the last to mention.

That would be the sticky issue of how to put on the brakes. I mean, what good is it to send a satellite or probe blazing a light speed path through space if it can only pass through, never being able to slow down and click a couple of snapshots or collect some atmospheric gas samples or drop off a few passengers? It ends up just being a real expensive slingshot with old, highly educated kids playing around with it.

And, if a craft can’t slow down, how in the heck could it maneuver around space debris? That pea shaped probe will get obliterated the first time it comes up against a chunk of space ice the size of a nickel. So, the gringa says, “Well, scientists, sounds like you folks need to get back to the drawing board. At first I was very excited and now I’m just aggravated that you got me all excited for nothing. I am not interested in a light year speed fly-by to Mars or a light year speed crash landing suicide mission.”

That’s when the scientists remind us of another option. We could use the array for protection. Yes, we can zap asteroids and space debris that threaten Earthlings. See, I told you Earth cats are in for it.

A Happy, Hopeful Astronaut


The gringa is happy to announce that she is one step closer to realizing her astronaut dreams! The media has given so much attention to SpaceX and their contractual relationship with NASA that the wonders of Blue Origin have not received their due. And, for aspiring astronauts like myself, this is a terrible injustice that the gringa hopes to rectify with this humble blog post.

Blue Origin is making it possible for astronaut hopefuls to reach dizzying heights above the Earth. Space pioneers will soon launch into Earth’s atmosphere in the New Shepard capsule that is perched above a sixty foot rocket that has proven its re-useable capabilities long before SpaceX claimed such fame. They had successful launches and landings November, 2015, and this month, January, 2016.

The New Shepard can sit a six man crew and accelerate past 3G’s, that’s faster than Mach 3. And, although each crewman does have duties aboard ship, there is plenty of time for space explorers to kick back and gaze out some enormous windows upon the vastness of outer space that surrounds our beautiful planet. Once the New Shepard capsule separates from the rocket booster, passengers then experience weightlessness in the perfect stillness of the vacuum of space.

Where does all of this amazingness happen? Practically in the gringa’s back yard, right here in Texas, west Texas to be more exact. Very soon Flyboys and Flygirls will begin arriving at the launch site and go through a two day training course on what to expect as well as what your astronaut responsibilities will be. There are flight simulations, safety briefings and in-depth flight training on procedures, communications and maneuvering.

Launch day starts at sunrise for pre-flight checks and final clearance. Once the go ahead is given, space explorers climb in, batten down the hatch, strap in, and COUNT DOWN. The launch is a 150 second burn of the ride of your life! In no time the blue sky fades to black, yeah, just like the Metallica song. Astronauts get to explore the weightlessness of zero gravity, contemplate man’s place in the Universe, and make spaceflight history.

Earthbound mission control will signal when it’s time to get your feet back on the ground. So, strap back in and be prepared for an even faster trip back down (over 5Gs!) that will be slowed by eight drag brakes (technical-speak for parachutes). Right before touch down the rocket engine fires up and slows the booster for a 5 mph landing very close to the launch area.

Blue Origin’s motto is “Gradatim Ferociter” which is Latin for “step by step, ferociously”. Step by step they have built upon one success after another and broken new ground in the spaceflight industry. They are making it possible for EVERYONE (that has enough money, that is) to be an astronaut. In fact, Blue Origin wants to make it possible for millions of people to eventually live and work in outer space.

Although SpaceX has gotten more media attention for building a reusable rocket system, Blue Origin experienced this success first. With each flight, the cost of spaceflight becomes more and more affordable. Maybe it will be within the gringa’s budget in another five or ten years. Who knows?! But, one day, I’m going!

Blue Origin is perfecting their New Shepard flight program with ongoing tests of unmanned test flights. They have yet to put a crew up into the heavens. But, each test brings the day closer when astronauts like you and I, dear reader, will climb on board and make history!

And, if you’re not interested in getting shot up into the sky, you can still be a part of history by working for Blue Origin because they need lots of folks with skills! Just a few slots they need to fill:  Aerodynamics Engineer, Aerospace Technician, Avionics Engineer,  Avionics Software Development Engineer, Composite Structural Engineer, Dimensional Inspector, Director of Safety and Mission Assurance,  Dynamic & Loads Engineer, HelpDesk Technician, and the list goes on and on.

And you don’t have to necessarily relocate to West Texas to have one of these fantastic jobs. Blue Origin has facilities in Washington State and Florida, too. So, if you believe in no limits, are passionate about the space industry, and have something to offer to Blue Origin’s collaborative efforts, you need to check them out.

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.
