China's moon base control of USA -- USA must control space but libs can't figure it out!

Kurt Miller Really? Let China build a permanent colony on the Moon, and the first thing they will do is turn it into a military base. From there, China will use mass drivers to launch boulders at Earth, transforming them into artificial meteorites capable of vaporizing entire cities. Let China have the Moon, and we'll all be speaking Mandarin within a generation.
China has always dreamed of a world empire, and a military base on the Moon would give it to them.

The Cassini spacecraft recently got its last close views of Dione, a small icy moon orbiting Saturn, and the results are astounding.
Images returned from the Aug. 17 flyby show a mottled surface of craters and ice. One image shows Dione in front of the rings of Saturn, emerging from shadow. The closest approach brought the spacecraft to within 295 miles (474 kilometers) of the moon's surface.You can see more of Cassini's amazing Dione photos in our full gallery.
"I am moved, as I know everyone else is, looking at these exquisite images of Dione's surface and crescent, and knowing that they are the last we will see of this far-off world for a very long time to come," Carolyn Porco, Cassini imaging team lead at the Space Science Institute in Colorado, said in a statement from NASA's Jet Propulsion Laboratory.
Cassini has had four other close encounters with Dione since arriving at the Saturn system in 2004. Its closest approach was in December 2011, when it came within 60 miles (100 kilometers) of the satellite's surface.

During this last close encounter, the spacecraft only took a few images of Dione because the main goal of the flyby was to measure the moon's gravity, which will help scientists learn about its internal structure. This made imaging tricky because it wasn't Cassini's camera that was controlling where the spacecraft was "looking." Instead, Cassini was mostly studying Dione with its gravity science experiment, as well as instruments to measure the moon's magnetosphere (magnetic environment) and plasma (superheated gas), to help scientists understand processes on the moon's surface.
Cassini's last close encounter with Dione is one in a series of flybys scheduled for 2014. The spacecraft will make three final flybys of Enceladus — a geyser-spouting moon — on Oct. 14, 28 and Dec. 19. During the Oct. 28 flyby, the spacecraft will move through one of the plumes at a distance of as little as 30 miles (49 kilometers) from the surface.
Next year, Cassini's flyby schedule includes distant looks at the tiny Saturn moons of Daphnis, Telesto, Epimetheus and Aegaeon as well as a few icy moons. In the last year before the mission conclusion in late 2017, Cassini will move through the space between Saturn and its rings.

VIABLE US Manned Space Program-- THE ANSWER is HERE-- Gov. Support needed for several years THEN COMMERCIAL can TAKE OVER!

Don Nelson covers the proper steps the USA must take to have a viable manned space program. Government support is required since it is too expensive for private companies to go it on a strictly commercial basis. Eventually, the government can get out.

As Don has stated before, this is only viable approach for the USA to have a manned program. Cots & sls/ Orion will not meet our needs---- means end of USA manned program.

This link & nasaproblems.com details the correct USA approach!

End of US Manned Space program--- comment to open letter to Bho -- space news

Expat · 1 hour ago

"No one asks "what is the President's vision for transporting people from New York to Paris..."

Maybe because there already is a market in the private economy for flights from NY to Paris?

But there is NOT a market in the private economy for SpaceX to sell flights to and from orbit. This will be especially true in less than ten years when the Space Station goes away (and ten years is a best case scenario).

Here's a better analogy:

Smart people thought there was a market for commercial supersonic transport forty years ago. And after the technology was in hand and operational, that turned out (for a variety of reasons) NOT to be the case. Concorde service survived as long as it did because two governments subsidized its operations. When those subsidies were withdrawn, British Air and Air France retired the fleet. The Concordes were still flightworthy, but no one could afford to fly them (sound familiar? substitute Shuttle for Concorde...)

Same thing is looming for SpaceX and Boeing's manned capsules---when the ISS is retired (assuming they get their capsules operational before then) the government subsidies will likewise go away. And so will their manned capsules.

You can thank the Obama Administration for that on many levels, including his economic policies that have failed to produce US economic growth at the 5-6% levels we used to enjoy. So lower economic growth (both in the US and abroad) the fewer customers you will have for SpaceX to sell its very, very expensive tickets to for billionaire space tourists. No ISS? No market for space tourists? No SpaceX or Boeing capsules flying.

The End. Of US manned spacefllight, anyway.

'Eight Days in a Garbage Can': 50 Years Since Gemini V (Part 1)
By Ben Evans

Fifty years ago, this week, astronaut Charles "Pete" Conrad experienced "the longest thing I've ever had to do in my life." Gemini V was the third manned flight of NASA's two-man spacecraft, destined to clear many of the hurdles on the road to the first piloted lunar landing. Those hurdles included rendezvous, docking, spacewalking, a precision re-entry … and long durations of between eight and 14 days, the minimum and maximum anticipated lengths of a return trip to the Moon. On 21 August 1965, Conrad and his Gemini V command pilot, Gordo Cooper, blasted off on a mission which they had lightheartedly dubbed "Eight Days or Bust." Privately, they would come to refer to it, somewhat disparagingly, as "Eight Days in a Garbage Can."
Conrad's wait for a flight into space had been a long one. In early 1959, he had been summoned to Washington, D.C., for a series of interviews and physical and psychological tests in support of Project Mercury. He had not made the cut, because, it is said, he showed a little too much cockiness, irreverence, and independence during testing. (Conrad had famously looked at a blank Rorschach card and described it to the unimpressed psychologist as being "upside down.") His principal reason for rejection was that he was "unsuitable for long-duration flight," but he made the cut and was selected by NASA in 1962. Ironically, two of Conrad's four space missions would set new records … for long-duration flight!
Gemini V was the first flight of its kind to carry and utilize fuel cells to generate electrical power and enable longer durations. Since their assignment in February 1965, Cooper and Conrad and their backup crew of Neil Armstrong and Elliot See had put in punishing 16-hour working days, plus weekends, to meet a tight launch target of 1 August. This ludicrous schedule had to be relaxed. "We realized they needed more time," wrote Deke Slayton, the head of Flight Crew Operations, in his autobiography, Deke, and after consulting with senior management he succeeded in securing a three-week delay to 19 August.
Highly disliked in many quarters—not least by NASA Administrator Jim Webb—the "Conestoga wagon patch" of Gemini V was pushed through by Cooper and Conrad. Image Credit: NASA
Despite the pressure, Cooper and Conrad found time to give some thought to names for their spacecraft, even though NASA had officially barred them from doing so. Due to its pioneering nature, the two men wanted to call Gemini V "The Conestoga," after one of the broad-wheeled covered wagons used during the United States' push westwards in the 19th century. Their crew patch, in turn, would depict one such wagon, emblazoned with the legend "Eight Days or Bust." This was quickly vetoed by NASA managers, who felt it suggested a flight of less than eight days would constitute a failure, and Conrad's alternative idea—"Lady Bird"—was similarly nixed because it happened to be the nickname of the then-First Lady, wife of President Lyndon B. Johnson. Its possible misinterpretation as an insult could provoke unwelcome controversy. The astronauts, however, would not be put off and Cooper pleaded successfully with NASA Administrator Jim Webb to approve the Conestoga patch. However, the administrator greatly disliked the idea.
Preparations for Gemini V had already seen Conrad gain, then lose, the chance to make a spacewalk. According to a January 1964 plan, the Gemini IV pilot would depressurize the cabin, open the hatch, and stand on his seat, after which an actual "egress" would be performed on Gemini V, a transfer to the back of the spacecraft and retrieval of data packages on Gemini VI and work with an Agena-D docking target vehicle on subsequent flights. Following Soviet success on Voskhod 2, however, plans for a full egress were accelerated and granted to Ed White. The result: instead of "Eight Days or Bust," Gemini V would come to be described by Cooper and Conrad as "Eight Days in a Garbage Can"; they would simply "exist" for much of their time aloft, to demonstrate that human beings could survive for at least the minimum amount of time needed to get to the Moon and back.
Yet the Conestoga mission did have its share of interesting gadgets: it would be the first Gemini to run on fuel cells, would carry the first production rendezvous radar, and was scheduled to include exercises with a long-awaited Rendezvous Evaluation Pod (REP). Originally, it was also intended to fly the newer, longer-life thrusters, although these were ready ahead of schedule and incorporated into Gemini IV.

Only weeks after Cooper, Conrad, Armstrong, and See began training, in April 1965 fabrication of the Gemini V capsule was completed by McDonnell, tested throughout May in the altitude chamber, and finally delivered to Cape Kennedy, Fla., on 19 June. Elsewhere, the Titan II booster assigned to launch the mission was finished in Baltimore, Md., and accepted by the U.S. Air Force, and its two stages were in Florida before the end of May. Installation on Pad 19 followed on 7 June, and Gemini V was mounted atop the Titan on 7 July. Five days later, the last chance for an EVA on the mission was rejected by NASA Headquarters. There seemed little point in repeating what Ed White had already done, and, further, Cooper and Conrad, not wishing to be encumbered by their space suits for eight days, had campaigned vigorously for greater comfort in orbit by asking to wear helmets, goggles, and oxygen masks. The launch of Gemini V was scheduled for 19 August.
It would be a false start. Thunderstorms ominously approached the Cape, rainfall was copious, and a lightning strike caused the spacecraft's computer to quiver. The latter, provided by IBM, had caused concern on Gemini IV and, this time around, had been fitted with a manual bypass switch to ensure that the pilots would not be left helpless again. The attempt was scrubbed with 10 minutes remaining on the countdown clock, and efforts to recycle for another try on 21 August got underway.
On this second attempt, no problems were encountered. Aboard Gemini V, Cooper turned to Conrad. "You ready, rookie?" Conrad, white as a sheet, replied that he was nervous. Surely the decorated test pilot who had flown every supersonic jet the Navy owned wasn't scared? Conrad milked the silence in the cabin for a few seconds, then burst out laughing. "Gotcha!" he said with his trademark toothy grin. "Light this son-of-a-bitch and let's go for a ride!" And ride they did. At 8:59:59 a.m. EDT, Cooper and Conrad were on their way.
Ascent was problematic when noticeable pogo effects in the booster jarred the men for 13 seconds, but smoothed out when the second stage ignited and were minimal for the remainder of the climb. Six minutes after launch, as office workers across America snoozed away their Saturday morning, Gemini V perfectly entered orbit. Nancy Conrad wrote that her late husband compared the instant of liftoff to "a bomb going off under him, then a shake, rattle, and roll like a '55 Buick blasting down a bumpy gravel road—louder than hell."
"Let's go for a ride!" After one delay, Pete Conrad and crewmate Gordo Cooper finally got their chance on 21 August 1965. Photo Credit: NASA
Hitting orbit made Cooper the first man to chalk up two Earth-circling missions. (Gus Grissom, of course, had piloted a suborbital flight on Liberty Bell 7, before commanding the orbital Gemini 3.) However, Gemini V would shortly encounter problems. The flight plan called for the deployment of the REP, nicknamed "The Little Rascal," from the spacecraft's adaptor, after which Cooper would execute a rendezvous test, homing in on its radar beacon and flashing lights. Before the REP could even be released, as Gemini V neared the end of its first orbit, Conrad reported, matter-of-factly, that the pressure in the fuel cells was dropping rapidly from its normal 58.6-bar level. An oxygen supply heater element, it seemed, had failed. Nonetheless, as they passed over Africa on their second orbit, Cooper yawed the spacecraft 90 degrees to the right and, at 11:07 a.m., explosive charges ejected the REP.
Next, the flight plan called for Gemini V to maneuver to a point 7 miles (11.2 km) below and 16 miles (25.7 km) behind the REP, although much of this work was subsequently abandoned. However, Chris Kraft's ground team was becoming increasingly concerned as the fuel cell pressures continued to decline and when a pressure of 12.4 bars was reached this was insufficient to operate the radar, radio, and computer. Kraft had little option but to tell the astronauts to abandon their activities with the pod.
It seemed likely that a return to Earth would be effected and Kraft ordered four Air Force aircraft to move into recovery positions in the Pacific for a possible splashdown about 500 miles (800 km) northeast of Hawaii. A Navy destroyer and an oiler in the region were also ordered to stand by. Keenly aware of the situation, Cooper radioed that a decision needed to be made over whether to abort the mission or power down Gemini V's systems and continue, to which Kraft told him to shut off as much as he could. All corrective instructions proved fruitless: neither the automatic or manual controls for the fuel cell's oxygen tank heater would function. Nor could the heater itself, located in the adaptor section, be accessed by the crew. Cooper and Conrad even maneuvered their spacecraft so the Sun's rays illuminated the adaptor, in the hope that it might stir the system back to life. It was all in vain.

By now, most of their on-board equipment—radar, radio, computer, and even some of the environmental controls—had been shut down, and, as Gemini V swept over the Atlantic on its third orbital pass, there was much speculation that a re-entry would have to be attempted before the end of the sixth orbit, because its subsequent flight track would take it away from the Pacific recovery area. Then, as the astronauts passed within range of the Tananarive tracking station in the Malagasy Republic, off the east coast of Africa, Cooper reported that pressures were holding at around 8.6 bars, suggesting, Kraft observed, that "the rate of decrease is decreasing." As he spoke, the oxygen pressures dropped still lower, to just 6.5 bars, and fears were high that if they declined much further, Gemini V would need its backup batteries to support another one and a half orbits and provide power for re-entry and splashdown. The astronauts were asked to switch off one of the fuel cells to help the system, and as they entered their sixth orbit the pressures leveled-out at 4.9 bars.
Capcom Jim McDivitt asked Cooper for his opinion on going through another day under the conditions. "We might as well try it," replied Cooper, but Kraft remained undecided. After weighing all available options, including the otherwise satisfactory performance of the cabin pressure, oxygen flow, and suit temperatures, together with the prestige to be lost if the mission had to be aborted, he and his control team emerged satisfied that oxygen pressures had stabilized at 4.9 bars. If there were no more drops, Gemini V would be fine to remain in orbit for a "drifting flight," staying aloft just long enough to reach the primary recovery zone in the Atlantic, sometime after its 18th orbit.
Admittedly, with barely 11 amps of power, only a few of the mission's 17 experiments could be performed, but Kraft felt "we were in reasonably good shape … we had the minimum we needed and there was a chance the problem might straighten itself out." As Cooper and Conrad hurtled over Hawaii on their fifth orbit, he issued a "Go" for the mission to proceed. As the mission entered its second day, circumstances improved and pressures climbed. "The morning headline," Kraft radioed on 22 August, referring to a newspaper, "says your flight may splash down in the Pacific on the sixth orbit." Having by now more than tripled that number of orbits, Conrad replied that he was "sorry" to disappoint the media.
Notwithstanding the successes, the glitches continued. On 25 August, two of the eight small thrusters jammed, requiring Cooper to rely more heavily on their larger siblings and expend considerably more propellant than anticipated. It was at around this time that Gemini V broke Valeri Bykovsky's five-day endurance record, and Mission Control asked Cooper if he wanted to execute "a couple of rolls and a loop" to celebrate; the laconic command pilot, however, declined, saying he could not spare the fuel and, besides, "all we have been doing all day is rolling and rolling!" When the record of 119 hours and six minutes was hit, Kraft blurted out a single word: "Zap!" Gordo Cooper, with an additional 34 hours from Faith 7 under his belt, was now by far the world's most flown spaceman.
His response when told of the milestone was hardly historic … but matter-of-factly typical of Gordo Cooper: "At last, huh?"

'Eight Days in a Garbage Can': 50 Years Since Gemini V (Part 2)
By Ben Evans

Five decades have now passed since a mission which Pete Conrad once described as "the longest thing I've ever had to do in my life." Gemini V was the third manned flight of NASA's two-man spacecraft, destined to clear many of the hurdles on the road to the first piloted lunar landing. Those hurdles included rendezvous, docking, spacewalking, a precision re-entry … and long durations of between eight and 14 days, the minimum and maximum anticipated lengths of a return trip to the Moon. On 21 August 1965, Conrad and his Gemini V command pilot, Gordon Cooper, blasted off on a mission which they had lightheartedly dubbed "Eight Days or Bust." Privately, they would come to refer to it, somewhat disparagingly, as "Eight Days in a Garbage Can."
By 23 August, two days into the flight, that garbage can was shaping up quite nicely. As described in yesterday's AmericaSpace article, Gemini V ran into early difficulties which forced Cooper and Conrad to power down many of their systems, and the astronauts could complete only a handful of their scientific experiments. The result was that the men frequently had to endure long periods of drifting flight, with little to do. A dramatic reduction of available propellant made the last few days little more an endurance run. Flight Director Chris Kraft told the astronauts to limit their thruster usage as much as possible, and many of their remaining photographic targets, which required them to maneuver the spacecraft into optimum orientations, had to be curtailed.
Still, a range of high-quality imagery was acquired. These included panoramas of the southwestern United States, the Bahamas, southwestern Africa, Tibet, India, China, and Australia. Images of the Zagros Mountains revealed greater detail than was present in the official Geological Map of Iran. Cooper and Conrad also returned pictures of meteorological structures—including the eye of Hurricane Doreen, brewing to the east of Hawaii—together with atmospheric "airglow." In addition, they took pictures of the Milky Way, the zodiacal light, and selected star fields. Other targets included two precisely timed Minuteman missile launches and infrared imagery of volcanoes, land masses, and rocket blasts.

The scientific nature of many of these experiments did not detract—particularly in the eyes of the Soviet media—from the presence of a number of military-sponsored investigations. Cooper and Conrad's flight path carried them over North Vietnam 16 times, as well as 40 times over China and 11 times over Cuba, prompting the Soviet Defence Ministry's Red Star newspaper to claim that they were undertaking a reconnaissance mission. The situation was not helped by President Lyndon B. Johnson's decision, whilst the crew was in orbit, to fund a major $1.5 billion U.S. Air Force space station, known as the Manned Orbiting Laboratory (MOL). Among the actual military experiments undertaken by Gemini V were observations of the Minuteman plume and irradiance studies of celestial and terrestrial backgrounds, together with tests of the astronauts' visual acuity in space to follow up on reports that Cooper had made after his Faith 7 mission. Large rectangular gypsum marks had been laid in fields near Laredo, Texas, and Carnarvon, Australia, although weather conditions made only the U.S. site visible.
Cardiovascular experiments performed during the mission would reveal that both men lost more calcium than the Gemini IV crew, although principal investigator Pauline Beery Mack expressed reluctance to predict a trend, since "a form of physiological adaptation may occur in longer spaceflight." Medically, lead physician Dr. Chuck Berry's main concerns were fatigue and his advice was that they get as much sleep as possible. "I try to," yawned Conrad at one stage, "but you guys keep giving us something to do!" All in all, they managed between five and seven hours' sleep at a time and expressed little dissatisfaction with Gemini V's on-board fare: bite-sized, freeze-dried chunks of spaghetti and meatballs, chicken sandwiches, and peanut cubes, rehydrated with a water pistol. An accident with a packet of shrimp, though, caused a minor problem when it filled the cabin with little pink blobs. Conrad even tried singing, out of key, to Capcom Jim McDivitt at one point.
Years later, Conrad would recall that the eight-day marathon was "the longest thing I ever had to do in my life." He and Cooper had spent the better part of six months training together, so "didn't have any new sea stories to swap with one another … there wasn't a whole lot of conversation going on up there." Nancy Conrad would recall her late husband describing how the confined cabin caused his knees to bother him—their sockets felt as if they had gone dry—and that he would have gone "bananas" if asked to stay aloft any longer. He found it hard to sleep, hard to get comfortable, and the failures meant he and Cooper spent long periods simply floating with nothing to do. After the flight, he told fellow astronaut Tom Stafford that he wished he had taken a book, and this gem of experience would be noted and taken by the crew assigned to fly the 14-day mission. Nancy Conrad described Cooper's irritation at losing so much of his mission. He was far from thrilled that the two main tasks for Gemini V, rendezvous and long-duration flight, were becoming little more than "learning-curve opportunities" and suggested throwing an on-board telescope in the Cape Kennedy dumpster when it twice refused to work. Later, when the spacecraft was on minimum power and the astronauts were still expected to keep up with a full schedule, Cooper snapped, "You guys ought to take a second look at that!" As for physical activity, he grimaced that his only exercise was chewing gum and wiping his face with a cleansing towel.

On the ground, Deke Slayton was concerned that such an attitude would not help the command pilot's reputation with NASA top brass. Indeed, Gemini V would be Cooper's final spaceflight and, although he would later complain bitterly about "losing" the chance to command an Apollo mission, some within the astronaut corps would feel that Cooper's performance and strap-it-on-and-go outlook had harmed his career. Tom Stafford was one of them. "Gordo … had a fairly casual attitude towards training," he wrote in his autobiography, We Have Capture, "operating on the assumption that he could show up, kick the tires and go, the way he did with aircraft and fast cars."
To spice matters up still further, worries about the fuel cells continued to plague Gemini V's final days. Their process of generating electricity by mixing hydrogen and oxygen was producing 20 percent too much water, Kraft told Conrad, and there were fears that the spacecraft was running out of storage space. This water excess might back up into the cells and knock them out entirely. In order to create as little additional water as possible, the astronauts powered down the capsule from 44 to just 15 amps, and on 26 August Kraft even considered bringing them home 24 hours early, on their 107th orbit. However, by the following day, the water problem abated, largely due to the crew drinking more than their usual quota, and a full-length mission seemed assured.
Eitherway, they had long since surpassed Bykovsky's Vostok 5 record. In fact, by the time Cooper and Conrad splashed down, they would have exceeded the Soviets on several fronts: nine manned missions to the Reds' eight, a total of 642 man-hours in space to their 507, and some 120 orbits on a single mission to their 81. At last, after eight years in the shadows—first Sputnik, then Gagarin, Tereshkova, Voskhod 1, and Leonov—the United States was pulling ahead into the fast lane of the space race. When it seemed that Gemini V might come home a day early and miss the scheduled Sunday 29 August return date, mission controllers in Houston even played the song "Never on Sunday," together with some jazz.
The astronauts also had the opportunity on the last day of the mission to talk to an "aquanaut," Aurora 7 veteran Scott Carpenter, who was on detached duty to the Navy. Carpenter, who had broken his arm in a motorcycle accident a year before and been medically grounded by NASA, was partway through a 45-day expedition in command of Sealab II, an underwater laboratory on the ocean floor, just off the coast of La Jolla, Calif. The Sealab effort, conceived jointly by the Navy and the University of California's Scripps Institution of Oceanography, sought to discover the capacity of men to live and work effectively at depth.

The music, the chat with Carpenter, and Conrad's dubious singing did little to detract from the uncomfortable conditions aboard Gemini V. As they drifted, even with coolant pipes in their suits turned off, the two men grew cold and began shivering. Sleep was difficult. Chuck Berry had wired Conrad with a pneumatic belt around each thigh, which automatically inflated for two minutes of every six throughout the entire mission. The idea was that, by impeding blood flow, it forced the heart to pump harder and gain its much-needed exercise. Berry felt that if Conrad came through Gemini V in better physical shape than Cooper, who did not wear the belt, a solution may have been found for "orthostatic hypotension," the feelings of lightheadedness and fainting felt by some astronauts after splashdown.
For the two astronauts, that splashdown could not come soon enough. By landing day, 29 August 1965, their capsule had become cluttered with rubbish, including a litter of freeze-dried shrimp, which had escaped earlier in the mission. The appearance of Hurricane Betsy over the prime recovery zone prompted the Weather Bureau to recommend bringing Gemini V down early, and Flight Director Gene Kranz agreed to direct the USS Lake Champlain to a new recovery spot. At 7:27:43 a.m. EDT, Cooper fired the first, second, third, then fourth retrorockets, then gazed out of his window. It felt, he said later, as if he and Conrad were sitting "in the middle of a fire." Since it was orbital nighttime, they had no horizon and were entirely reliant upon the cabin instruments to control re-entry. In fact, Gemini V remained under instrument control until they passed into morning over Mississippi.
The parachute descent was smooth. No oscillations were evident and the 7:55:13 a.m. EDT splashdown was a gentle one. As would later be determined, the computer had been incorrect in indicating that they would overshoot. A missing decimal point in a piece of uplinked data had omitted to allow for Earth's rotation in the time between retrofire and splashdown. Cooper's efforts to correct the overshoot had progressively drawn them short of the recovery zone. "It's only our second try at controlling re-entry," admitted planning and analysis officer Howard Tindall. "We'll prove yet that it can be done."
Gemini V had lasted seven days, 22 hours, 55 minutes, and 14 seconds from its Pad 19 launch to hitting the waves of the western Atlantic, and the crew was safely aboard the Lake Champlain by 9:30 a.m. Despite the difficulties, most of Cooper and Conrad's objectives had been successfully met. Yet more success came when Chuck Berry realized that, despite the days of inactivity with little exercise aboard the capsule, the astronauts were physiologically "back to normal" within days, clearing the way for Frank Borman and Jim Lovell to attempt a 14-day endurance run on Gemini VII. The missions that followed would snatch victory from the jaws of defeat and set aside another obstacle on the path to the Moon.

Well, let's see. The LM Ascent stage gross weight at liftoff was ~10,300 lbs (earth weight) which would have been ~1716 "lbs" on the moon. The ascent engine thrust was ~3500 lbf. So the Thrust/Weight ratio was ~2.0.

Comparing that to the SPS engine thrust, which was ~20,000 lbf, suggests that it could lift ~10,000 "lbs" from the moon with the same acceleration, which translates to ~60,000 lbs earth weight. Not clear, however, how many engines the original concept envisioned because the stack would have been heavier to include the fuel needed slow down to land; but that may have been a separate descent stage. The total weight of the CSM + LM at TLI ignition was ~100,000 lbs (64,000 lbs CSM and 36,000 lbs LM). So Wayne's blog is very plausible.

One other benefit, from a trajectory control standpoint, is that when going into and coming out of orbit around the moon, the larger the thrust, the shorter the burn time and the shorter the burn arc, which simplifies guidance.

Thanks to Wayne's Bog, as I did not know the Apollo SM SPS engine was oversized.

Specific Plans
Posted on August 7, 2015 by waynehale
"A long term strategy and corresponding plans must also be developed . . . a set of notional milestones, launches, and hardware developments that are sufficiently defined so as to allow a cost estimate" – NASA Advisory Council finding April 2015
There is a story, perhaps apocryphal, that in the backseat of the car from NASA Headquarters to the White House to brief President Kennedy on the possibility of a moon landing, the legendary NASA Administrator James Webb decided to double the estimated cost of the program. Whether that part is true or not, the Webb estimate delivered that day in the spring of 1961 was significantly lower than the actual Apollo program.
Norman Augustine's famous book of "Laws" concerning government acquisition states that all program cost estimates are subject to a correction factor of [1+ 0.52/(1+8t3)] where t is the percent of the procurement period completed. Or as he finishes the chapter with Law XXIV: "The most unsuccessful three years in the education of cost estimators appears to be fifth-grade arithmetic."
During the so-called Space Exploration Initiative (SEI) days of the late 1980's, the '90-day-study' came up with a very detailed plan to go to Mars . . . and the cost estimate made that plan dead on arrival at Congress. This lesson has not been lost on the NASA leadership.
A historical example may be in order. Look at the Apollo program hardware, specifically the Service Module and its rocket system the SPS (Service Propulsion System). That rocket engine is tremendously more powerful than the subsequent lunar landing flights needed. Why was such a large rocket engine installed on the Apollo SM? In 1961 when the first real plans for lunar landing were baselined, Direct Lunar Ascent was the designated mode. Some sort of huge lander would drop the entire CM/SM stack onto the lunar surface and the SPS had to be big enough to lift the astronauts, the Command Module, and the Service Module off the lunar surface and put them on a trajectory for the Earth.
To put that big stack – the CM/SM and the Landing Stage on a trajectory to the moon, the puny Saturn V was not big enough. Developing a much larger rocket was required – they called it Nova. Nova would have twice the number of F-1 engines as the Saturn V, tanks twice the diameter, much taller, more stages, etc., etc., etc. Exactly how the Nova rocket would be built was never figured out – it would be too big to fit under the ceiling of the factory at Michoud where the Saturn V first stage was made. The notions of how to transport that rocket to the launch pad were . . . notional.
Then along came some bright boys at Langley headed by John Houbolt who advocated an operationally more complex idea called Lunar Orbit Rendezvous – which only needed the Saturn V already under development.
The Nova rocket, the 100 foot tall Lunar Descent Stage, all went in the dust bin of history were never developed. But the contract for the SPS engine had already been let. Any real need to downsize that engine? No, but much less propellant would be carried in the tanks. If the Apollo CM/SM were somehow magically transported to the surface of the moon, the SPS had enough oomph to lift them off . . . but probably not enough gas onboard to get very far.
LOR was a good idea. Lots of folks are proposing ideas for future space travel. Some of them are actually pretty good. Locking a plan down means new, good ideas can't complete.
History cries out with lessons. Some of them are subtle. Having detailed plans is generally good; believing in them too much is not. In the military they are fond of quoting the maxim: "No battle plan survives its first encounter with the enemy". In space, the enemy is physics and chemistry . . . and finances. It may be that flexibility and leaving options open provides a better path for our long term ambitions in space. Who knows what may be invented in the next five years that could change the entire game plan?
Would we have made it to the moon if we tried to build the Nova rocket to do it? Maybe, maybe not.
The wrong plan can easily come with a forecast cost – a shock to the system – such that the program is never approved. Having a reasonable plan for the next step while keeping the goal in sight might actually be better. Waiting a little while doing some testing and development might be a good idea. Finding creative ways of controlling costs is mandatory.
Meanwhile, anybody seen Zephram Cockrane out there? Or at least the ghost of John Houbolt?

Look at this fantastic vehicle & it's unique capabilities, America desperately needs this capability, per George Abbey in his lost in space article in Washington Examiner , July 15, 2015, we must get this capability back with a expanded X37B. Jim Hillhouse of American Space agrees as do many experts. We must get the attention of Congress . I urge you to blog about this & spread the word!!
