Warning incoming Space Rant: It is time for the Agency to Pivot
With a new president coming in just about 6 months from now it is time to be proactive and admit the current journey to Mars mirage is nothing more than a hashtag. Instead of waiting for the coming blue ribbon panel and revector let's take the hard look at the situation and get out infront of things by being honest and laying out a more thoughtful strategy for achieving Mars in 20 years. It may garner a knee jerk reaction from certain circles but if they are truly in it for exploration and not just jobs/contracts then they can find their way through to actual deep space exploration not just lobbying about it.

Step 0: Give up building launch vehicle and orion. They are albatrosses around our neck. A heavy lifter for use 20 years from now sucks up way more budget than relying on multiple launches and robotic assembly which is needed anyway. Plus since we are going with a reusable Mars transit vehicle crew loading and unloading can occur in earth orbit serviced by one of the many commercial crew vehicle coming online. How much more Mars technology could we fund if we free up SLS/Orion funds. Don't worry congress folks and old space wanting to suckle at the government tit of cost plus contracts there will be plenty of pork to spread around with the new plan. Don't bring up the suck cost fallacy cause continuing to pour money for something 20 years down the road while you starve all the tech that is truly needed for Mars is only going to continue the myth that going to Mars is within the next 20 years. Staying the course is not the answer if you really want to actually make progress.

Forward plan Step 1: Best case we plan for upcoming commercial heavy lift like falcon 9H worst case we design for existing HLV. Either way we can cross that bridge to pick a launcher 12 years from now when we start locking down the design . Since crew rotation occurs in LEO it should be no different than what we will be paying for astronauts to the ISS in the next couple of years and entry speeds will be similar as well.

Step 2: time to stop iterating on an evolvable Mars campaign and hand out a design to the agency to start building.
We need a clean sheet 90 day study to pick a design so that the technology investment can start working towards putting things together. This gets divided up among the centers (see Congress we will spread things around) and gets everyone on the same path and garners support for the pivot from congress and incoming president.

It will help focus on what can be commercially sourced versus what needs internal development. We dont need to be spending money on our limited use case for something the commercial market is going to far surpass our needs down the road. We just need to have a viable onramp plan for the cots 10+ years from now. the study will provide the focus needed so no more centers working on what they think they should instead of what the politics/HQ wants. If we are infusing $3B in tech we need to make sure the design is anchored so that they are building the ins/outs/size/volume/power for the integrated systems/ mission operations parameters.

We can reevaluate every four years to ensure the tech tree is bearing fruit or if we need to pick a new branch and what the launch vehicle situation is. For now we start with existing HLV and it only gets better from here at the next review in 4 years.

Step 3: Develop LEO to Lunar cycler
Now that we have SLS out of the way the plan is whichever HLV we use just has to get the mass to LEO. Our solar electric propulsion tug will move it out to the lunar shipyard. This gives us run time on sep that will eventually grow to the transit vehicle size. The cycler also gets to test out deep space navigation (like pulsar/x-ray) and autonomous deep space rendezvous and docking.

Step 4: Use Cycler to build out lunar shipyard
Robotic assembly, radiation protection methods and testing of "MCC in a Box" autonomy gets shaken out as the the two Mars Transit Vehicles are built up. Eventually there could be living quarters for science and telerobotics to lunar surface it would require a hab attachment for the cycler since we scrapped orion but that becomes a long term closed loop eclss test bed so bonus points. The human occupation of the shipyard appeals to the international partners as it gets them closer to lunar surface

Step 5: Large scale technology investment
With the SLS/orion money freed up that gives us about $3B a year to put towards the major hurdles for Mars like radiation, EDL, autonomy, ISRU, closed loop ECLSS, robotic helpers, fecal processing, nuclear power and more. These tech are currently on the slow road to Mars due to budget restrictions that would go away with a $3B infusion. At least a portion of this should be to try out Moonshots that may fail but if they succeed are 10X leap forward to Mars.

Step 6: at the shipyard build two reusable transit vehicles
First is cargo delivery for all the preposition of assets for upcoming human missions. We can use an opposition class mission since it is unmanned and 30 day stay in Mars orbit should be enough time for precision placement of the necessary hardware. This robotic hauler will deploy early EDL and isru test beds while testing out larger class SEP, navigation and autonomy.
Second is crew transit vehicle the culmination of tech investment and precursor testbeds. Allows for longer conjunction class missions for a crew to spend 500 days on the surface.

If we as an agency, country, world really want to move up the gravity well to exploring Mars then let's take a hard look at where we are and pivot to get there.

Apollo 11 halfway to home


HOUSTON - Down right chatty, the Apollo 11 astronauts joked and described more details of their mission as earth’s gravity tugged their spaceship ever faster toward home. At 1:28 a.m. they passed the second signpost on their celestial journey - the halfway point in their curving trip from the moon. At that point they were 167,000 miles from earth. 

They put on a kind of “Mr. Wizard” television show for earthlings Tuesday night as astronaut Mike Collins presented what he called “a little demonstration for the kids.” He held some water upside down in a spoon to show that it was unaffected by gravity, but adhered to the spoon by cohesion. 

Ed Aldrin used a can of ham spread to demonstrate how a gyroscope works and later showed a piece of bread floating around the cabin. 

Collins also demonstrated the water pistol used to deliver liquids under pressure to the astronauts. He accidentally squirted himself in the face.

Actually sounds like an interesting idea. Gives some jeopardy to the whole situation, will he have a son Jor-el and grandson Kal? As opposed to the false jeopardy in the prequels will Anakin and obiwan survive of course cause we know of they end up. With this it will be up in the air maybe.

Looks pretty good. Are you ready to play?

I am still not sure about this show
The look and feel just doesn't seem to fit with the prime universe given it takes place what 10 years before Kirk and Spock. Some of the specie costumes//tech doesn't natural evolution from this to Kirk/spock

48 years ago we left the Moon for the first time
while beating the Russians to the Moon was important bringing them home was also key.
10 more men would walk on the surface and then we decided to anchor ourselves to the shallow waters for the next 40 years.

July 21st 1969

1:11:13 am EST
After 22 hours on the surface of the moon, Luanr EVA operations is complete and the Crew closes the hatch for the last time in preparation of departing the surface.

9:44 a.m.
Shortly after arousing Collins, still circling the Moon in the Command/Service Module, Mission Control observes: "Not since Adam has any human known such solitude as Mike Collins is experiencing during this 47 minutes of each lunar revolution when he's behind the Moon with no one to talk to except his tape recorder aboard Columbia."

11:13 a.m.
The astronauts in Eagle are aroused. Aldrin announces: "Neil has rigged himself a really good hammock . . . and he's been Iying on the hatch and engine cover, and I curled up on the floor."

12:42 p.m.
Answering a question raised before they went to sleep, Aldrin reports: "We are in a boulder field where boulders range generally up to two feet, with a few larger than that... Some of the boulders are Iying on top of the surface, some are partially exposed, and some are just barely exposed."

1:52 pm EST
The Lunar Module ascent engine is ignited and departs to rendezvous with the waiting Mike Collins in the Command Module.

4:35 pm
The Ascent stage is docked with the Command Module. After more than hour of leak checks Buzz and Neil enter the Command Module.

6:41 pm
The crew jettisons the ascent stage and performs several seperation burns.


Radio Moscow makes a brief announcement: "Luna XV has. ..completed
its mission". In other words, the craft has crashed.
