Images designed by Andy Saunders, author of “Apollo Remastered,” show NASA Experimental lunar module “Orion” Charles Duke Enjoy the view across Descartes’ mountainous heights, the command and service module “Casper” over the lunar horizon, Commander John Young’s “Giant Leap”, the lunar module and a portrait of the Duke and his family on the lunar surface.
The second of the three “J-missions” Apollo 16 Main objectives In order to examine, survey and sample materials and surface features in the highlands region of the southeast quadrant of the Moon, to set up and activate surface experiments and perform in-flight experiments and photographic missions from lunar orbit.
The lunar module carrying Young and Duke in Descartes touched down – albeit roughly six hours late – at 9:24 p.m. EDT on April 20, about 276 meters northwest planned point.
There were two significant problems with the command module, one en route to the moon and the other in lunar orbit, which contributed to the landing delay and the subsequent one-day early mission termination.
Indicates wrong signal Gimbal lock steering system During the trans-moon coast phase, it was neutralized by real-time programming and the standby circuit caused oscillations in the service’s propulsion system, delaying the circular burn-in of the command module.
The lunar module landing continued until engineers decided that the oscillations would not seriously affect the steering module of the command module.
During more than 71 hours and two minutes of staying on the surface, the astronauts explored the area through three extravehicular activities (EVA), which lasted 20 hours and 14 minutes.
The first EVA involved preparing the Lunar Roving Vehicle and deploying the Apollo Lunar Surface Experiments Package (ALSEP), and the heat flow experience was lost when Young tripped and broke the electronics cable.
The astronauts collected samples and photographed Flag Crater, took the first measurement with a lunar magnetometer at Spook Crater and published the Solar Wind Formation Experiment at the ALSEP site.
They collected core, surface and trench samples in the Cinco Craters region during the second EVA, and measurements of the lunar surface-borne magnetism were taken near Cinco.
Time restriction in meeting the ascent schedule cut Eva III short, as House Rock, Shadow Rock, and crater rim samples were sampled. lunar magnetometer Measurement readings were taken there and at the roving parking site, along with the final samples. Finally, they recovered a file Solar wind formation and film from a far UV camera/spectrometer.
Command Module Pilot Thomas K. Ken Mattingly circled the moon with cameras and Scientific Device Unit (SIM) Gulf Instruments that were operating during Young and Duke’s stay on the Moon and verified Apollo 15 data and information about the lunar terrain.
In conclusion, Young and Duke collected 209 pounds of samples and drove the rover 16.6 miles.
The lunar lift-off occurred on April 23 at 8:26 p.m. EDT.
The lunar module was phased out after normal rendezvous and docking and lost altitude removing the usual de-orbit maneuver and planned impact.
The planners chose to recreate the mission a day early — and after an 83-minute spacewalk by Mattingly shooting cassettes from the SIM slot — they littered the The Pacific Ocean Before 3 p.m. EDT on April 27.
The total mission time was 265 hours and 51 minutes, or just over 11 days.
In particular, particles and fields The satellite It was launched on April 24 at 4:56 p.m. EDT to investigate the moon’s mass, gravitational changes, the particle composition of space near the moon, and the interaction of the moon’s magnetic field with that of the Earth.
Saunders noted that when Mattingly noticed a problem with the main engine in the command module, the three astronauts had to remain in a visible position in lunar orbit for the four hours it took for the mission controller to assess the problem.
Saunders said Duke’s photo – which shows the command module above the lunar surface with the blue Earth rising – conveys the enormity of their accomplishments.
Duke, who left a picture of his family on the moon after the third extravehicular activity, told him it was an emotional moment.
While the image likely quickly faded and turned, Saunders is sending a copy of the image in a small capsule to the moon this year on the deck of the dismounted ship. Al Shaheen Purple Landing Vehicle.
