However, data from Apollo 11, which had not sent its LM ascent stage crashing into the moon as in subsequent missions, showed that its mechanisms could survive seven or eight hours in space without water cooling.
The crew conserved water. The crew became dehydrated throughout the flight and set a record that stood up throughout Apollo: Lovell lost 14 pounds and the crew lost a total of Those stringent measures resulted in the crew finishing with Removal of carbon dioxide also was a concern. There were enough lithium hydroxide canisters, which remove carbon dioxide from the spacecraft, but the square canisters from the command module were not compatible with the round openings in the lunar module environmental system.
There were four cartridges from the LM and four from the backpacks, counting backups. However, the LM was designed to support two men for two days and was being asked to care for three men for about four days. After a day and a half in the LM, a warning light showed that the carbon dioxide had built up to a dangerous level. Mission control devised a way to attach the CM canisters to the LM system by using plastic bags, cardboard and to tape all materials carried on board.Social Proof and Pre-Selection: How To Build Attraction Based On Science - Preview 4
One of the big questions was, "How to get back safely to Earth? Before the explosion at 30 hours, 40 minutes, Apollo 13 had made the normal midcourse correction, which would take it out of a free-return-to-Earth trajectory and put it on a lunar landing course. Now the task was to get back on a free-return course. The ground computed a second burn and fired it five hours after the explosion. As they approached the moon, another burn was computed; this time a long five-minute burn to speed up the return home.
It took place two hours after rounding the far side of the moon. The command module navigational platform alignment was transferred to the LM, but verifying alignment was difficult. Ordinarily the alignment procedure uses an onboard sextant device, called the Alignment Optical Telescope, or AOT, to find a suitable navigation star.
Then with the help of an onboard computer, it verifies the guidance platform's alignment. However, due to the explosion, a swarm of debris from the ruptured service module made it impossible to sight real stars.
An alternate procedure was developed to use the sun as an alignment star. Lovell rotated the spacecraft to the attitude Houston had requested and when he looked through the AOT, the sun was just where it was expected. The ground and crew then knew they could do the five-minute P. At 73 hours, 46 minutes into the mission, the air-to-ground transcript describes the event: I think we got it. What diameter was it? It's coming back in. Yes, yaw's coming back in. What have you got?
Upper-right corner of the sun If we raised our voices, I submit it was justified. Flight Director Gerald Griffin, a man not easily shaken, recalled: My writing was almost illegible, I was so damned nervous.
And I remember the exhilaration running through me: My God, that's the last hurdle - if we can do that, I know we can make it. It was funny because only the people involved knew how important it was to have that platform properly aligned. The trip was marked by discomfort beyond the lack of food and water. Sleep was almost impossible because of the cold. When the electrical systems were turned off, the spacecraft lost an important source of heat.
The temperature dropped to 38 degrees Fahrenheit and condensation formed on all the walls. The most remarkable achievement of mission control was quickly developing procedures for powering up the CM after its long, cold sleep. Flight controllers wrote the documents for this innovation in three days, instead of the usual three months. The command module was cold and clammy at the start of power-up.
The walls, ceiling, floor, wire harnesses and panels were all covered with droplets of water. It was suspected conditions were the same behind the panels. The chances of short circuits caused apprehension, but thanks to the safeguards built into the command module after the disastrous Apollo 1 fire in Januaryno arcing took place. Lovell recalled the descent to Earth, "The droplets furnished one sensation as we decelerated in the atmosphere: Photos of the service module showed one whole panel missing and wreckage hanging out, it was a mess as it drifted away.
Three hours later, the crew left the lunar module Aquarius and then splashed down gently in the Pacific Ocean near Samoa. After an intensive investigation, the Apollo 13 Accident Review Board identified the cause of the explosion. Inthe CM had undergone many improvements that included raising the permissible voltage to the heaters in the oxygen tanks from 28 to 65 volts DC. Unfortunately, the thermostatic switches on these heaters weren't modified to suit the change.
During one final test on the launch pad, the heaters were on for a long period of time. This subjected the wiring in the vicinity of the heaters to very high temperatures Fwhich have been subsequently shown to severely degrade teflon insulation. The thermostatic switches started to open while powered by 65 volts DC and were probably welded shut.
Linear regression models revealed that lunar illumination influenced the timing of diel activity in pacas Tab. This finding suggests that other variables may influence C.

By evaluating the responses in diel and nocturnal activity of pacas in the Brazilian Amazon to abiotic variables such as degree of lunar illumination, we have provided insights for the ecology and conservation of the species.
Through the breakdown of temporal activity from coarse scale to hourly periods we have also demonstrated the importance of considering the temporal scale in understanding species responses over the 24 hours diel cycle.
Diel and nocturnal activity patterns The diel periods of activity we found for pacas generally agree with previous studies which have shown that the species is predominantly nocturnal EMMONS et al. Previous authors have reported that C. Lunar phobia in nocturnal mammals can be explained by one of two strong selective pressures: Previous studies have explained lunar phobia in C. However, we have found that paca activity measured as the frequency of photos per lunar illumination class did not differ significantly with lunar illumination i.
These small canopy gaps enable increased levels of lunar illumination to reach the forest floor when compared to primary forest areas such as those surveyed in the present study, which have a dense overstory. In our study area, the dense canopy effectively limits the amount of lunar illumination reaching the forest floor even on the brightest nights. In our southern Amazonian forest sites lunar illumination was the only variable that weakly explained variation in the timing expressed as time after sunset of diel 24 hours and nocturnal activity for pacas.
Our regression analysis revealed that neither of the other abiotic variables investigated rainfall and temperaturenor illumination, provided any convincing explanation of the variation in the patterns of "when" pacas were active. Besides the tapetum lucidum, pacas also have retinal ganglion cells, which have been shown to integrate information from wider areas of the visual spectrum compared with diurnal species such as agoutis - Dasyprocta spp.
These ganglion cells are thought to be an adaptive advantage that facilitates the processing of visual information at low light levels HUGHES Therefore, the predominance of nocturnal activity in pacas is to a large extent "hard-wired" by evolutionary constraints.
Within the limits imposed by evolutionary constraints, paca exhibit variation in activity that is not directly explained by lunar illumination or other abiotic factors. The unexplained variation in temporal activity of pacas found in our study area may be caused by variations in unmeasured covariates such as habitat structure and predation risk.
As a consequence, Neotropical rodents such as pacas may be adopting a more flexible behavior, with reduced predator densities "releasing" them from the limiting effects of predation risk.
Therefore, reduced predation risk enables pacas to be active across the entire lunar cycle, without the need to avoid strongly illuminated nights.
