Re: NSS Houston Chapter Events

Emergency procedures:

Every pressure sub-compartment will have pressure sensors. I case of pressure lock, an alarm will sound with both sound and flashing strobe light. If pressure is lost, the alarm will not be audible, so the light will be necessary. The common equipment box on the roof of every pressure compartment will include water filtration to convert grey water to potable, compressor for air conditioning, battery to store electricity, and pressurized bottle of oxygen to repressurize in case of pressure loss. If only one sub-compartment loses pressure, alarm will only sound there, and oxygen will be proved in an attempt to maintain pressure long enough for passengers to evacuate. Once pressure cannot be maintained, pressure tight doors along the corridors will automatically close and seal shut. At the base of every spoke there will be a storage closet with emergency equipment. This will include a plastic sheet airlock. Every pressure door will have a seal built into the door frame around the door, on both sides. The floor will have a section that covers the portion of this seal under the door, and will cover the track where the door slides. Pressure tight doors will be sliding pocket doors. When a pressure door closes, the cover that acts as a walking surface will be pushed up and out of the way by the door itself. That cover will be mounted on a hinge, and can be moved further away from the door to expose the pressure seal around the door. The plastic sheet airlock can be affixed and sealed there. When the airlock is decompressed, it will want to collapse, so cords will be built into the plastic sheet airlock to hold it open, and anchors built into walls to attach those cables. A spacesuit will also be in the compartment with emergency equipment. A crewman can don the spacesuit, and go through that temporary airlock to enter the compartment that has decompressed. If any passengers are still inside, the crewman can go in to rescue them. Safety equipment will include NASA rescue balls, two for each safety equipment closet.

Interior of the ship will have a number of security cameras, each the size of a smartphone camera. These cameras will include optical and infrared. Security cameras will feed to a server in the security office. These cameras will give security ability to determine if anyone is still inside a sealed pressure compartment, so they can tell rescue crewmen how many and where passengers are that require rescue.

Although life support is designed to make each pressure compartment independent, power will be shared throughout the ship. And potable water can be moved from one compartment to the next. And oxygen. Several lines between compartments: power, internet data, potable water, oxygen, concentrated starch/water solution, concentrated urine, misc liquid sewage, powdered feces (moved with pressurized air and an auger). Power and internet data lines will be sealed so no air can flow around the lines if the compartment is sealed. All fluid lines will have two valves to seal it closed, one on each side of the pressure bulkhead. All lines will automatically seal closed when the pressure door is sealed, but the bridge can override.

The ship will have Wifi throughout. However, primary data will be via optical cable. Repeaters and switches will be radiation hardened and protected from EMP. The TV in each cabin will be a smart TV, with optical cable connection. The TV can be used for streaming video from a server on the ship (located in an equipment bay on the bridge). A number of other entertainment services. But the TV can also view streaming video from any of the high definition streaming video cameras on the outside of the ship. If a passenger wants to see what's going on outside, they can do so with the TV. Everything the TV can access will also be available to mobile devices via Wifi: smartphones, tablets, laptops. An ethernet port will be available for each bunk, should a passenger wish a cable connection. That outlet will also have USB-A and USB-C, so mobile devices can charge as well as get high speed data.

If a Solar Proton Event (SPE) should occur, all passengers will be required to move to the habitation ring. The zero-G hub at the centre of the ship will be the reception foyer to receive passengers when a Starship docks. It will also be departure foyer. An elevator in each spoke will connect the ring to the zero-G hub. Aft of the zero-G hub will be a zero-G cargo hold. A hatch will connect the two zero-G compartments. Cargo as well as food for the journey will be stored there. Parts of the cargo hold will be dry storage for packaged food, some will be "walk in" (float in) freezer for frozen food. In case of an SPE, the zero-G hub and zero-G cargo hold will be off-limits. The upper level of the ring will have greenhouses, advanced life support such as processing concentrated urine, two observation rooms, and a Mars simulation room. These will all be off-limits in case of an SPE.

Beside the elevator at the base of each spoke, there will be a stairway to the second level. That stairway will lead to either an observation room, or EVA prep area of the Mars simulation room. Three spokes, one stairway to each upper level room. Reminder: the Mars simulation room will have the same pressure, gas mix, and roughly the same gravity as outside on the surface of Mars. The prep room will have storage for real spacesuits, and a real airlock will connect the prep room to the Mars simulation room. The simulation room will have some air pressure, about 7 millibar, so will be sealed so no passengers can fall overboard. Each stairway will have a pressure door built into the floor of the upper level room. The door will close horizontally, creating a pressure seal between the upper level and lower. The lower end of the stairway will have a more conventional pressure door. The stairway itself will act as an airlock. So if an upper level room becomes compromised, it can be sealed off too.

Is said each pressure compartments will have an equipment box on the roof. That will actually be located on the floor of a second level room, so within a pressurized space. A crewman could open the equipment box for maintenance. It could be a sealed box in the middle of an observation room, or EVA prep room, or greenhouse. Each greenhouse will be accessible by pressure tight door to an observation room or EVA prep room. Door to a greenhouse will be locked, only crewman will have access.

Elevator can stop at the second level, opening to an observation room or EVA prep room. Elevators will be sealed, so they can maintain pressure in case an elevator shaft decompresses. A horizontal pressure door can seal off the elevator shaft between the lower and upper level of the ring, and another between the upper level and spoke. At the zero-G hub, another horizontal pressure door can seal the elevator station from the rest of the shaft. Doors to the elevator station, and doors to enter the elevator car will seal pressure tight whenever closed.

The gym will be the only facility that covers two levels of the ring. The upper level will be open to below in the centre, with a stairway between levels. This will give the appearance of a double height ceiling, and individuals standing on the lower level of the gym will be able to see people in the upper level, and vice versa. Due to this open space, floor area of the upper level will be half that of lower. The gym will not have any windows.

Air circulation fans will be able to blow air down corridors, and each cabin will have a vent that can exchange air with the corridor. Public areas will not have dedicated oxygen recycling: gym, restaurants, kitchens, bar, laundry, security, bridge, sick bay. However, air exchanged down corridors will provide fresh air. The gym will exhaust air directly into greenhouses. Air from greenhouses will be exchanged with public areas and corridors. Primary oxygen recycling will be sized to provide all oxygen required for each cabin, with maximum number of passengers in that cabin. However, if a cabin has fewer passengers then that cabin may not have all chloroplast bags installed. However, the zero-G hub will contain replacement chloroplast bags, stored frozen. Additional chloroplast bags can be thawed and installed. Of course this means plants in greenhouses provide backup oxygen generation. Or fewer chloroplast bags installed.

One of the greenhouses could grow pea plants to 14 days after germination. With equipment to harvest leaves, chop them up, and process to isolate chloroplasts. Additional empty plastic bags will be stored, and the old bags of chloroplasts can be emptied, washed out, and loaded with fresh chloroplasts. The greenhouse will also have the ability to "grow out" the special pea plants to produce seed.

Greenhouses will have transparent ceiling to allow sunlight in, reflected by an outside mirror. Observation rooms, and Mars simulation room will have transparent window walls from waist to ceiling, and transparent ceiling. All windows will be two panes of aluminum oxynitride to provide protection from micrometeoroids. Gap between panes filled with air that is lower pressure than interior, but higher pressure than the vacuum of space. Pressure in that gap will be monitored. If pressure drops, then the outside pane has a leak; if it rises then the inside pane is leaking. The EVA prep room and airlock to the Mars simulation room will not have any windows. Rooms on the second level that do not grow plants, for example areas that process concentrated urine, or vats to convert starch to sugar, will not have transparent ceiling.

Every outside cabin will have one porthole window to the outside. Since aft cabins will face the Sun, that means windows pierce the water wall. On this side, porthole windows will be filled with mineral oil. That mineral oil will provide radiation shielding. Radiation "hot cells" from the 1950s used a windows composed of glass with the intervening space filled with mineral oil. It's excellent radiation shielding, carbon in mineral oil is lighter than oxygen in water, so even better for heavy ion radiation. All windows on the habitation level will have a shutter than can close over the window. The shutter will be mounted on a hinge, on the outside of the hull. This shutter will have thick micrometeoroid shielding, to protect the window should something approach. They'll look very similar to the shutters for the cupola on ISS.

The docking hatch will be on the front of the ship, right at the axis of rotation. This will be larger than the APAS docking hatch for ISS. It will have shock absorbers similar to APAS, but sufficient for the mass of Starship, and the hatch large enough to allow cargo to pass through. I think a circular hatch, but diameter equal to the diagonal of a CBM hatch. An arm outside the ship will hold an adapter. This adapter will provide pressure attachment to the main hatch, and the other side compatible with the NASA Docking System (NDS). That smaller hatch will be compatible with SpaceX Dragon, Boeing Starliner, Orion, or Sierra Nevada Dream Chaser. For safety, a protection cover can be closed over the NDS hatch. Of course there will be an airlock between the docking hatch and the zero-G hub.

I am considering a second airlock. This would be in the side of the zero-G cargo hold. This airlock would be sized to allow an entire Dream Chaser to enter. Since the side will rotate at 3 RPM, the same rate as the rest of the ship, there's a procedure for a Dream Chaser to enter there. The airlock would be depressurized and the outside hatch opened. Dream Chaser would orient itself with aft end toward the hull of the zero-G cargo hold, and approach closely. Once rotation of the ship causes the open hatch to pass Dream Chaser, a tray would extend from the airlock. This tray would be mostly an open frame, but with pads that align with tires of Dream Chaser landing gear. Dream Chaser would extend landing gear before approaching. When the ship rotates so the pads of this tray "smack" the tires of Dream Chaser, a clamp would click grab the landing gear, holding Dream Chaser to the tray. The cargo hold is 9 metres diameter, so the hill will be moving past at 28.28 metres per minute = 0.47124 metres per second. The tray a little faster due to increased radius of rotation. Once vibration stabilizes from capture, the tray will retract into the airlock, bringing Dream Chaser in with it. The outer hatch will close, then the "boat bay" repressurize. Note: at this point Dream Chaser will have it's nose pointed away from centre of rotation, so "down" will be towards the windshield, though centrifugal force that close to centre of rotation will be very slight. An inner pressure hatch will allow crew access from the zero-G cargo hold. The inner hatch will be compatible with NDS so crew could transfer even if the "boat bay" is not pressurized.

The ship will carry one space telescope attached to a cradle on the outside of the cargo hold. Hubble has a 2.4 m (7 ft 10 in) mirror, and the forward tube has an inside diameter the same, but the aft equipment bay is larger. This ship's telescope will have a primary mirror the same diameter, but instruments will be modern and smaller, giving the aft part the same diameter. If modern image sensors are better, the telescope could have a primary mirror slightly smaller than Hubble, but image resolution must be the same. Modern solar arrays, so smaller. And this telescope will have ability to detach, free flying beside the ship during transit, but capturing back into the ship's cradle for planetary orbital insertion.

The ship will also have a separate free-flying navigation drone. This drone will have star-sight telescopes for celestial navigation, high resolution digital gyros for inertial navigation, and ability to measure distance and relative position from the ship very precisely. This will be attached to its own cradle on the outside of the zero-G cargo hold. And the ship will carry a number of inspection drones. These inspection drones will each have a camera about the size of a smartphone camera, but very high resolution. Outside of inspection drones covered in soft material (rubber? styrofoam?) so it won't do any damage if it bumps into the ship. And the inspection drones will use cold gas thrusters. Total size of inspection drones about that of a softball. Inspection drones will be stored in a small bay that can pressurize, allowing access to drones by crew from inside the ship. The navigation drone will have solar arrays, but inspection dones won't. All drones and the space telescope can recharge batteries from the Ship when docked, and refill propellant tanks.

The main docking hatch for SpaceX Starship will have fluid transfer quick disconnect couplings outside the docking hatch, integrated with the docking mechanism. The Russian docking hatch on ISS has such a fluid transfer couplings; it can transfer water, oxygen, and propellant from a Progress cargo ship. Soyuz spacecraft dock to the same hatch, but just don't have fluid transfer couplings. The Large Ship will have couplings to accept water, oxygen, nitrogen, propellant for RCS thrusters, and propellant for mid-course correction thrusters.

There will be RCS thruster quads on the outside of the habitation ring. With propellant tanks located outside the pressure hull, adjacent to each thruster quad. Propellant tanks outside the main airlock, close to the docking hatch. Propellant feed lines outside the pressure hull will transfer propellant from those first tanks, along the outside of the zero-G hub to spokes, down spokes to the ring, and outside the pressure hull to propellant tanks at each thruster quad. Propellant transfer lines will also extend along the circumference of the hull to allow transfer of propellant between thruster quads. Propellant lines and tanks will have micrometeoroid shielding.

The ship will take 6 months from Earth to Mars. If something should go wrong, this is a free return trajectory to return to Earth. "The Case For Mars", 1996 soft-cover edition, page 84, lists preferred trajectory. Earth-Mars will take 6 months, but return will take 18 months, so total flight time 2 years. The ship will have food and life support supplies for 6 months. How do you feed 1,000 passengers and 60 crew for that time? The ship will be very well sealed, so very little air leakage, hopefully none. The life support system on ISS must dump toxic gasses in space: CO2 and methane. Some oxygen and water could be lost with those gasses. The Sabatier Reactor consumes half of CO2 scrubbed from cabin air, but the rest is dumped. Various proposals have been made to recover some oxygen from that CO2, all of which produce various other toxic gasses. Whenever dumping anything in space, there's the risk some oxygen or water will be lost. Life support on the Large Ship is based on chloroplasts, so byproduct is starch. Feces are vacuum desiccated then ground to a powder; that powder is stored in a container attached to the outside of the ship. Proposed location: near the docking hatch, so containers can be removed for transport down to Mars. The containers will have vacuum, so air must be recovered from powdered feces. That is a potential for air loss, but very little. Expect negligible atmosphere loss during transit.

Oxygen is recycled. Water is recycled. Pressure is maintained. Air conditioning is run by electricity, so temperature is maintained as long as there's power. Solar panels for electrical power generation, so electricity as long as the Sun shines. Plants in the greenhouse powered by direct sunlight. Chloroplasts powered by sunlight as well, so minimal power requirement for oxygen recycling. Salt, banking soda, and yeast nutrient are extracted from human urine, so they're recycled. Chloroplast oxygen generators produce starch, so that will never run out. A vat will grow a specific species of mould using water and starch, producing amylase. Another vat will convert starch to sugar using amylase, so that will never run out. Another vat will produce microbial oil, equivalent to vegetable oil, using water and sugar and yeast nutrient. That means cooking oil will never run out. Processed human urine will also produce sodium hydroxide and potassium hydroxide, when added to microbial oil that makes liquid soap. So hand soap will never run out. Liquid soap with a milder pH is shampoo, so shampoo for showers will never run out. Another formulation for laundry soap, and another for dishwasher soap. Waste soap will be added to misc liquid sewage, which is decomposed to fertilizer for hydroponics. So what's left? All passengers need is food.

Fresh salad is grown in greenhouses. If we do develop a microbe that can produce wheat protein, that will be mixed with starch from chloroplasts to make all-purpose flour. Synthetic, but close enough. We can bake bread on the ship. Another microbe can make different wheat protein, when mixed with starch will make semolina flour. Semolina makes pasta. Microbial oil can be processed to make margarine. Some of the oil will have hydrogen bubbled over a platinum catalyst to partially hydrogenate. Regular oil mixed with partially hydrogenated oil will be more firm. Add salt and lemon juice and colour to make margarine. For colour, I suggest turmeric. It's bright, and the plant can be grown in a pot in one of the observation rooms. It makes a pretty decorative plant. We can also make pancakes, waffles, and syrup. Pancake syrup is 2 cups golden yellow sugar (aka light brown sugar), packed, add 1 teaspoon imitation maple extract, and 1 cup boiling water. Yellow sugar is made with white sugar and molasses. So all we need to make syrup is molasses and imitation maple extract. I could explain how to make that extract, but it's best made on Mars (or Earth) rather than the ship. Simple syrup is just white sugar in hot water.

Last resort: dissolve starch in water, cook in a microwave oven to breakup starch. Add a pinch of yeast nutrient, bread yeast, and let ferment for 3 days at room temperature. Then cook again in a microwave oven. Result has consistency of pudding, white and translucent, with the flavour and aroma of freshly baked bread. The yeast adds a little protein, lipids, and all the B vitamins except B12.

For those who like the bar, vodka is just sugar, water, yeast nutrient, and distiller's yeast. Ferment for 5-10 days (depending on temperature) then distill. Vodka is distilled to 60% to 70%, then diluted with clean water. So vodka will never run out. Gin is made with vodka, juniper berries, and various botanicals. We can grow those in pots in one of the observation rooms. There won't be a lot of gin, juniper plants won't produce berries very often, perhaps with an expert gardener once every 6 months. But some.

We can grow dwarf orange trees and dwarf lemon trees in pots in the other observation room. There are current varieties that produce full-size fruit, but trees only grow ~8 feet tall plus the height of the pot.

::Edit:: I didn't mentioned the mini-magnetosphere. Based on work by University of Washington. Expected to reduce radiation to 1/3 that of interplanetary space. That would reduce radiation to equal that of ISS. Because ISS is in Low Earth Orbit so protected by Earth's magnetosphere. However, not the zero-G hub is at the axis of rotation. During a Solar Proton Event, the mini-magnetosphere would concentrate radiation at the magnetic poles, which would be aligned with the ships rotation axis. So the engine section at the aft end and the zero-G hub at the forward end would exposed to concentrated radiation. Another reason the the zero-G hub must be evacuated during an SPE.

Re: NSS Houston Chapter Events

The video had the feel of mission control with the three panels of people in view.

video address
https://youtu.be/V1Y8fupdmGc

I watched a bit on the NSS website and then from the youtube site and it was a bit better on it as the screen was just a little larger.

The youtube site has a comment area that if you have a login we might have one post about the newmars website forum on it to attract more users for the project and for the forum as well...
Put the content of how to find the topic and the means to become a newmars user.

Re: NSS Houston Chapter Events

I am happy to be able to report that Dr. Johnson's talk is online:

https://www.northhoustonspace.org/

The walk-around-microphone he was wearing is battery powered.
The battery gave out just as the Q&A period opened, so audio is spotty from that point.

I am working with the chapter to see if we can add mouse pointer movements to the video.

Per SpaceNut, here is the direct link: Here is the embedded link for GW

2:10 PM – Recent Space News – Greg Stanley
2:40 PM – Featured Speaker – Tracking Satellites – Charles Phillips
3:45 PM – Socializing
4:00 PM – End of Meeting

Tracking Satellites:
The discussion will be a (non-technical) overview of how to track satellites from the Houston area. It is possible to track satellites with inexpensive equipment and easily available software. The discussion will include WHY a person would track satellites and also HOW it is done. The existing Satellite Catalog will be briefly discussed and why some satellites are not shown in that catalog. The discussion is designed to give an overview so an interested person could decide if they want to get more involved and can determine what they might need to generate observations.

About the Speaker:
Charles Phillips started tracking satellites in 1978 when he was in the US Air Force, he was an orbital analyst. He came to Houston in January 1985 as an Air Force flight controller at the Johnson Space Center, his first flight as a qualified flight controller was STS-51L. In 1990 he started as a civilian flight controller for Spacelab Life Sciences flights and worked STS-40 and STS-58. He also supported the NASA/Mir program and the ISS.

About the Meeting
Meetings are open to all age groups and interest levels. Come explore with us the potential that developing and exploring space has to better life here on earth and to open up new frontiers creating new perspectives that can help enrich the human experience.

The Vision of NSS is people living and working in thriving communities beyond the Earth, and the use of the vast resources of space for the dramatic betterment of humanity.

The Mission of NSS is to promote social, economic, technological, and political change in order to expand civilization beyond Earth, to settle space and to use the resulting resources to build a hopeful and prosperous future for humanity. Accordingly, we support steps toward this goal, including human spaceflight, commercial space development, space exploration, space applications, space resource utilization, robotic precursors, defense against asteroids, relevant science, and space settlement oriented education.
