AS11-36-5352 - Earth at about 181,000 km or 98,000 nautical miles. North is left with the Greenland icecap visible. 11 anecdotes surprenantes sur Apollo 11. JULY 17, 1969. 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. He also commanded the Gemini 12 flight in which Buzz Aldrin was his pilot. Apollo 11 Highlights . CAPCOM Rog. The normal range for combustion pressure (i.e. Diagram to show the substellar points for near and far horizons. Day 2 . 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. Sounds from Apollo 11 "We have a liftoff": Commentary: Thirty seconds and counting. As Buzz talks to Mission Control, music can be faintly heard in the background each time he keys his microphone. 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! Given that burn, we expect an orbit of 61 by 169.2 … 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. Strictly speaking, it is the difference in pressure between the tunnel and the CM cabin. 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. CAPCOM Roger, Neil. This dish antenna can automatically track a ground station by sensing when it is going slightly off track. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. North is approximately up with the Greenland icecap visible. 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. Also visible are Arabia, Asia and Europe, particularly Spain. 0000005916 00000 n At some point between 10 and 30 hours, Buzz begins to transmit video to Earth. Based on measurements of Earth's image on the scanned film of Hasselblad magazine N, it is likely that four photographs were taken around this time; three in quick succession and the fourth a few minutes later. %PDF-1.3 %���� Image by LPI, AS11-36-5357 - Earth at about 205,000 km or 111,000 nautical miles. Liftoff! When Mike attempted to carry out a navigation exercise before their sleep period, it didn't go too well. 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]. It's grown quite quiet here in Mission Control. Delta-V; 2,917 feet per second [889 m/s]. is view is inside the H LM cabin. It is unclear what Buzz means by 'P23 damage'. It appeared in many prominent publications, including on the cover of the best-selling Penguin paperback. Mission Control want the dump to go ahead soon so that radio tracking after the burn will be inclusive of the dump's effects. Jim Lovell is referring to his and Buzz's flight in Gemini 12. How does it look? We're showing spacecraft weight now as 96,159 pounds [43,617 kg]. Postmarked way back in 1969, 50 years on, these incredibly nostalgic original First Day Covers are now very hard to find. Image by LPI. This clip is kindly donated by Mark Gray. McCandless has asked for a Verb 66 which is an instruction to make a copy of the state vector that is in the CSM slots of the computer and put it in the LM slots. 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. And Bruce McCandless is back on the CapCom console now. Day 3 . Durant la mission, Neil Armstrong et Buzz Aldrin (Michael Collins n’ayant pas quitté Eagle, le module lunaire ou véhicule qui les a transportés jusqu’à la Lune) ont notamment posé un drapeau américain sur la Lune, installé un réflecteur laser (pour calculer facilement la distance Terre-Lune) et un sismomètre (pour mesurer les vibrations sur sol), et récolté environ 20 kgd’échantillons du sol lunaire. The Guidance Officer reports Apollo 11 is now in the attitude for the midcourse correction. Belay that last announcement. Voici 11 anecdotes surprenantes sur la mission Apollo 11. Apollo 11 est une mission du programme spatial américain Apollo au cours de laquelle, pour la première fois, des hommes se sont posés sur la Lune, le 21 juillet 1969. Image by LPI, AS11-36-5360 - Earth at about 210,000 km or 113,500 nautical miles. In Mission Control, the backup commander of Apollo 11, Jim Lovell, has temporarily taken the CapCom position. We have not contacted them within the last hour, and have not heard from them. It is possible for Mission Control to remotely switch the antenna but often they request that the crew carry make the switch. 0 Apollo 11 passes into Earth's shadow at 194:36:41 and around that time, Buzz takes some 16-mm footage of a very thin crescent disappearing into black. Neil has the LM holding its attitude using the AGS. 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. As they manoeuvre, the signal from the spacecraft weakens and becomes noisier. If the valve is in any other position, then the gauge reading is meaningless. AS11-36-5358 - Earth at about 210,000 km or 113,500 nautical miles. Image measurement and triangulation suggests that two photographs are taken around this time. If the spacecraft is rolling in its Passive Thermal Control mode, a set of four omnidirectional antennae mounted at 90° intervals around the periphery of the CM are brought into play. EAGLE The Eagle has wings. 0000008450 00000 n Over. T-15 seconds, guidance is internal. This is Apollo Control at 102 hours, 12 minutes into the flight of Apollo 11. The Atlantic Ocean dominates the view with the South American continent lower right. 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. It was set to the value of Delta-V. Noun 87 presents the optics calibration data. North is right and the African continent is prominent. However, since a valve in the LM's overhead hatch has been deliberately left open, the reading will reflect the pressure in the LM cabin also. Mike is carrying out a realignment of the spacecraft's guidance platform using Program 52 in the computer. Download MP3 audio file. Your lowly editor had determined that the crew are listening to 'Angel of the Morning' by Merrillee Rush and the Turnabouts which was a hit in 1968. 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. Additionally, Mission Control can remotely switch between antennas B and D on the crew's behalf. 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. The sextant's optical magnification is 28 times, which makes it an excellent instrument with which to study the now distant Earth. This is Apollo Control. This is Apollo Control. Some 51 minutes remaining in the scheduled sleep period for the crew of Apollo 11. He did say that he did break this rule on several occasions, using shots from Apollo 8's propulsive push rather than Apollo 11's but that he would document where he used different clips from other launches. 0000001321 00000 n 0000000716 00000 n This display is static. 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. Twenty seconds and counting. Apollo 11 was the first flight to send people to the moon. 0000000989 00000 n It focuses on the 1969 Apollo 11 mission, the first spaceflight from which men walked on the Moon. We see you in there. North is right and the African continent is prominent. Directed by Olaf Held. All systems aboard the spacecraft performing well. 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. Kevin Clemens | Jul 17, 2019. Image by LPI, AS11-36-5353 - Earth at about 181,000 km or 98,000 nautical miles. One instance of this prompts McCandless to think that the crew were calling. On July 20, 1969, Armstrong and Aldrin became the first humans to land on the moon, while Collins stayed in orbit around the Moon. 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. North is left with the Greenland icecap visible. This is Apollo Control. Your browser does not support the audio element. 0000001637 00000 n Image by LPI. On awakening, the crew of Apollo 11 receive some updates to their Flight Plan, and perform some spacecraft maintenance activities. 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. 0000005181 00000 n Image by LPI, AS11-36-5355 - Earth at about 182,500 km or 98,500 nautical miles. Animation of AS11-36-5354 and 5355 to show the rotation of the planet between the two photos. July 17 marks Day 2, the day of the launch. 0000006560 00000 n Tower clear. Apollo 11 Highlights . EAGLE Looking good. North is approximately up with the Greenland icecap visible. 0000010588 00000 n The idea was that he would manoeuvre the spacecraft in order to aim the sextant's fixed line of sight at Earth's horizon. Image by LPI, AS11-36-5354 - Earth at about 181,000 km or 98,000 nautical miles. 0000004003 00000 n The Command Module has four low-gain omnidirectional antennae spaced around its periphery, designated A to D, which can be used instead of the High Gain Antenna. 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. Day 5 . Apollo 11 is a 2019 American documentary film edited, produced and directed by Todd Douglas Miller. CAPCOM Roger. Mark. 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. T-25 seconds. Apollo 11 is now going out of the Passive Thermal Control mode in which it was slowly rotating to maintain thermal balance. CapCom Bruce McCandless is passing up some changes in the procedures for this navigational operation. Spain and western Sahara are near the terminator. That's the midcourse navigation. 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. They make their first Midcourse Correction by firing the Service Module engine, photograph the Earth, and listen to some music over lunch. This is Apollo Control; 21 hours, 38 minutes Ground Elapsed Time. Apollo 11 was the spaceflight that first landed humans on the Moon.Commander Neil Armstrong and lunar module pilot Buzz Aldrin formed the American crew that landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC (14:17 CST).Armstrong became the first person to step onto the lunar surface six hours and 39 minutes later on July 21 at 02:56 UTC; Aldrin joined him 19 minutes later. the pressure in the combustion chamber as a result of burning) is 95 to 105 psi (655 to 724 kPa). N, U, N, K, I. Apollo 11 is now in Program 52 which is re-alignment of the platform prior to beginning the cislunar navigation operation. In the next chapter, they resume viewing the Earth as the spacecraft rotates in Passive Thermal Control mode. That reading was the difference in pressure between the Lunar Module cabin and the Command Module cabin. Apollo 11 should have started this long burn; duration 6 minutes, 2 seconds. Apollo 11: This past week marked the 50th anniversary of Apollo 11. The values he will come up with, in Noun 93, are -0.493° in X, -0.191° in Y and -0.024° in Z. 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. 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. 0000009594 00000 n The two stars that he will use are star 36 (Vega, Alpha Lyrae) and 37 (Nunki, Sigma Sagittarii). AS11-36-5356 - Earth at about 205,000 km or 111,000 nautical miles. 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. CAPCOM 11, Houston, the definition is pretty good on our monitor here. The regularly scheduled time for the television transmission is 6:47 pm Central Daylight Time, and we are anticipating that that transmission will occur as scheduled.
