In the last couple of hours of their second day in space, the crew of Apollo 11 return their spacecraft to the Passive Thermal Control roll, they try to observe a laser fired at them through a telescope in Texas, then they settle down for the night. Your browser does not support the audio element. Image by LPI. CAPCOM 11, we’re really amazed at the quality of the picture up in the tunnel. Mike is carrying out a realignment of the spacecraft's guidance platform using Program 52 in the computer. We said, if it didn't happen on that day at that specific time, we're not using it." Europe in on the left with the Mediterranean Sea and western Sahara Further right. %%EOF This is Apollo Control. North is left with the Greenland icecap visible. the pressure in the combustion chamber as a result of burning) is 95 to 105 psi (655 to 724 kPa). The Atlantic Ocean dominates the view with the South American continent at the lower part of the globe. That will then become the starting point for Mike's P23 determination of the state vector. Image by LPI, AS11-36-5353 - Earth at about 181,000 km or 98,000 nautical miles. More specifically, Mission Control had given him accurate attitude angles that ought to have placed this at the substellar point, a point that is the nearest or furthest point on the planet's limb from the star with which the angle is being measured. Sounds from Apollo 11 "We have a liftoff": Commentary: Thirty seconds and counting. That's the midcourse navigation. At some point between 10 and 30 hours, Buzz begins to transmit video to Earth. In other words, a mere 3-second burn of the SPS engine at this stage of the coast will change the height at which they pass above the Moon's far side by over 200 kilometres, an illustration of the sensitivity of celestial mechanics. Apollo 11 now being tracked by the tracking station at Madrid. Kevin Clemens | Jul 17, 2019. is view is inside the H LM cabin. In the middle of this pause, there seems to be some very low-level modulation that might be Buzz trying to talk on the air/ground. It is unclear what Buzz means by 'P23 damage'. AS11-36-5352 - Earth at about 181,000 km or 98,000 nautical miles. If the valve is in any other position, then the gauge reading is meaningless. And Bruce McCandless is back on the CapCom console now. Apollo 11 - Day 3 (Full Mission)18th July 1969 - This video starts at GET 43h 29m and covers the third day of the flight. Apollo 11 Highlights . This midcourse maneuver should reduce the pericynthion of Apollo 11's trajectory from the present 175 nautical miles [324 km] to 60 nautical miles [111 km]. 0000005218 00000 n The trunnion angle is then reduced to bring the image of the same star through the Star Line Of Sight (SLOS) to be superimposed on the LLOS image. APOLLO 11 DAY TWO. CAPCOM Roger. As a check of their attitude, the manoeuvre PAD included a star, number 30 (Menkent, Theta Centaurus) that ought to be in the sextant's field of view when the spacecraft is properly orientated and the instrument's shaft and trunnion angles are as prescribed. This display is static. We have a liftoff ... 32 minutes past the hour, liftoff on Apollo 11. 0000005181 00000 n The color’s not too (garbled) at least on this set. EAGLE Looking good. 0000007795 00000 n h�b```b``�``a`����ˀ �@1V �� �02. Come the time of the midcourse correction burn, it is vital that the spacecraft be in the correct attitude so that the force applied by the engine will be in the right direction. EAGLE The Eagle has wings. Europe in on the left with the Mediterranean Sea and western Sahara Further right. Neil has the LM holding its attitude using the AGS. Neil Armstrong a également, en posant le pied sur la Lune, prononcé une phrase devenue célèbre : 1. Image by LPI, AS11-36-5355 - Earth at about 182,500 km or 98,500 nautical miles. July 17 marks Day 2, the day of the launch. 0000001321 00000 n Day 3 . NASA.gov brings you the latest images, videos and news from America's space agency. Apollo 11 - Day 8 Part 2 (Full Mission)24th July 1969 - The video starts at GET 185h 25m some 9.5 hours before re-entry. Could you describe what you’re looking at, over? It went up to space on July 16, 1969, carrying three astronauts: Neil Armstrong, Buzz Aldrin and Michael Collins. Day 2 . By measuring the rotation of the planet between the last two images, it appears that 5355 was taken about 13 minutes after 5354. 0000008450 00000 n The two stars that he will use are star 36 (Vega, Alpha Lyrae) and 37 (Nunki, Sigma Sagittarii). The idea was that he would manoeuvre the spacecraft in order to aim the sextant's fixed line of sight at Earth's horizon. This latter axis derives it name from the supporting cylinders that emanate from the sides of an old-fashioned cannon to allow it to pivot in altitude. Liftoff! The crew switch their communications to operate through one of the Command Module's omnidirectional antenna, Omni A. His accuracy in this instance is excellent as shown by a display of 'all balls' for Noun 05, the star angle difference. This dish antenna can automatically track a ground station by sensing when it is going slightly off track. CAPCOM Rog. 887 0 obj <>stream With a newly aligned platform and a fresh state vector, the spacecraft's computer should be well-placed to calculate an accurate attitude to aim the sextant's fixed line of sight at the substellar point for the coming P23 cislunar navigation exercise. Delta-V; 2,917 feet per second [889 m/s]. That was Buzz Aldrin giving the description of what he could see on the Earth. Apollo 11 about to be acquired at the Tananarive station. 0000006560 00000 n Voici 11 anecdotes surprenantes sur la mission Apollo 11. North is approximately up with the Greenland icecap visible. We are showing an orbit now of 107 by 105.7 nautical miles and an orbital period of 1 hour, 28 minutes, 30 seconds. Those cylinders were known as trunnions and engineers took this term for the sextant's tilting arrangement and therefore we get a trunnion angle for the star line of sight which can be up to 50° away from the fixed line of sight. It’s available in 4K and HDR and is one of the most amazing films I’ve ever seen. Note that the pressure gauge that Mike is reading is only connected across either side of the forward hatch when the Tunnel Vent Valve is in its "LM/CM Delta-P" position. Some 51 minutes remaining in the scheduled sleep period for the crew of Apollo 11. Apollo 11 Command Module pilot Michael Collins spent part of July 17, 1969 describing to a TV audience how astronauts eat while in space. 0000009023 00000 n One of these near-identical images, perhaps 5354 as it seems to be marginally sharper, has been widely reproduced as one of the most famous Earth photographs taken during the Apollo program, and was extensively used by the environmental movement. The values he will come up with, in Noun 93, are -0.493° in X, -0.191° in Y and -0.024° in Z. How does it look? Day 5 . PAO Buzz Aldrin reporting that he’s halfway into the LM. 2 minutes from time of predicted acquisition of the Apollo 11 spacecraft. SC Hey, we’re about to open our hatch now. We got aif you wi, ll give 2 and data, we got the for loads you. This is Apollo Control at 102 hours, 12 minutes into the flight of Apollo 11. July 17, 1969. SC You’re seeing Earth as we see it out our left-hand window, just a little more than a half Earth. This is a comparison of the actual and measured angles between these two stars. Normally only two of these antennae are used; B and D on opposite sides of the spacecraft, but these have to be switched every 10 minutes as the spacecraft rotates. This is Apollo Control. When it does so, it takes with it a tilting prism arrangement that yields a moveable line of sight superimposed upon it. A flight dynamics officer reports that, in terms of distance, Apollo 11 will reach the half-way mark at 25 hours, 0 minutes, 53 seconds. A possibility is that Mike is looking to see how his copy of the state vector, the one in the LM slots, has changed with his sightings. Apollo 11: This past week marked the 50th anniversary of Apollo 11. Distance is now 103,263 nautical miles [191,243 km]. It is worth noting that with the objectives of the optics being mounted on the upper part of the CM's conical surface, the LM actually obscures a substantial amount of their field of view. 0000000716 00000 n This is Apollo Control; 21 hours, 38 minutes Ground Elapsed Time. We're now 2 minutes, 53 seconds from reacquiring the spacecraft; 21 minutes, 23 seconds from the beginning of the powered descent to the lunar surface. CAPCOM Roger, Neil. All systems aboard the spacecraft performing well. Apollo 11 Highlights . The moment of docking is given in the Apollo 11 Mission Report as 128:03:00. To take the PAO's explanation further, star 40 is Altair (Alpha Aquilae). Tower clear. Directed by Olaf Held. This clip is kindly donated by Mark Gray. It's grown quite quiet here in Mission Control. Additionally, Mission Control can remotely switch between antennas B and D on the crew's behalf. North is up and the African continent is prominent. Having 'zeroed the optics' which brings the shaft angle to its centre, zero-degrees parking position, the procedure requires that a star be viewed through the sextant's fixed line of sight (known as LLOS or Landmark Line Of Sight in the documentation). The residuals are on the order of a half a foot a second or less, and will not be trimmed. Spain and western Sahara are near the terminator. 0000001637 00000 n They make their first Midcourse Correction by firing the Service Module engine, photograph the Earth, and listen to some music over lunch. Image by LPI, AS11-36-5357 - Earth at about 205,000 km or 111,000 nautical miles. Doctor Aviation recaps the week. Remarkably, the master die used to create the stamp actually travelled to the Moon’s surface on board the Apollo 11 module with Neil Armstrong and Buzz Aldrin! Over. AS11-36-5358 - Earth at about 210,000 km or 113,500 nautical miles. 0000000016 00000 n He also commanded the Gemini 12 flight in which Buzz Aldrin was his pilot. Image by LPI, AS11-36-5360 - Earth at about 210,000 km or 113,500 nautical miles. During periods of no communication, when there is good reception from the spacecraft, it is not unusual for a little of the crew's conversation to break through onto the radio link, though very distorted. Noun 87 presents the optics calibration data. Apollo 11 Highlights . North is right and the African continent is prominent. The sextant's arrangement has a fixed line of sight which can be rotated 360° around a shaft, giving the shaft angle. That reading was the difference in pressure between the Lunar Module cabin and the Command Module cabin. North is approximately up with the Greenland icecap visible. The film consists solely of archival footage, including 70 mm film previously unreleased to the public, and does not feature narration, interviews or modern recreations. 867 0 obj <> endobj It is possible for Mission Control to remotely switch the antenna but often they request that the crew carry make the switch.

AS11-36-5356 - Earth at about 205,000 km or 111,000 nautical miles. It was set to the value of Delta-V. On awakening, the crew of Apollo 11 receive some updates to their Flight Plan, and perform some spacecraft maintenance activities. Apollo 11, U.S. spaceflight in which astronauts Neil Armstrong and Buzz Aldrin became the first people to walk on the Moon. EAGLE Your Eagle’s undocked. North is approximately up with the Greenland icecap visible. MCC number 2 in the Flight Plan will in fact be the first Midcourse Correction actually carried out, because MCC-1 was deemed unnecessary and was cancelled. Postmarked way back in 1969, 50 years on, these incredibly nostalgic original First Day Covers are now very hard to find. 0000000989 00000 n 0000010588 00000 n He described the blue of the oceans, the swirl of the clouds, and went on: "Can pick out the browns in the landforms pretty well. This is the Delta-V counter mounted on the EMS panel. 0000005462 00000 n With William F. Naumann. The attitude angles that the onboard computer came up with to aim the fixed line of sight at the substellar point on Earth's horizon, also happened to hide Alpheratz behind the LM, which perhaps says a litle about the lack of sophistication of the CMC's software. On July 21, 1969 some strange phenomena occurred in parts of the USA and made many Americans go crazy. APOLLO 11, DAY 2: Fifty years ago today, Apollo 11 has passed the halfway point in its journey and was speeding toward the moon at 5,000 mph. Astronauts report it feels good. The Atlantic Ocean dominates the view with the South American continent at the lower part of the globe. %PDF-1.3 %���� 0000005686 00000 n The Atlantic Ocean dominates the view with the South American continent lower right.
