apollo 11 day 2

%%EOF Apollo 11 Highlights . 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. 0000005916 00000 n AS11-36-5358 - Earth at about 210,000 km or 113,500 nautical miles. 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]. During this upcoming pass, we'll have our second excursion on the part of the Apollo 11 crew into - into the Lunar Module. Apollo 11 should have started this long burn; duration 6 minutes, 2 seconds. 0000009023 00000 n 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. NASA.gov brings you the latest images, videos and news from America's space agency. The color’s not too (garbled) at least on this set. This is a comparison of the actual and measured angles between these two stars. 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. Apollo 11, U.S. spaceflight in which astronauts Neil Armstrong and Buzz Aldrin became the first people to walk on the Moon. We're showing spacecraft weight now as 96,159 pounds [43,617 kg]. He also commanded the Gemini 12 flight in which Buzz Aldrin was his pilot. On July 20, 1969, Armstrong and Aldrin became the first humans to land on the moon, while Collins stayed in orbit around the Moon. 2 minutes from time of predicted acquisition of the Apollo 11 spacecraft. In the next chapter, they resume viewing the Earth as the spacecraft rotates in Passive Thermal Control mode. Strictly speaking, it is the difference in pressure between the tunnel and the CM cabin. Diagram to show the substellar points for near and far horizons. Sounds from Apollo 11 "We have a liftoff": Commentary: Thirty seconds and counting. Could you describe what you’re looking at, over? Apollo 11 - Day 3 (Full Mission)18th July 1969 - This video starts at GET 43h 29m and covers the third day of the flight. His accuracy in this instance is excellent as shown by a display of 'all balls' for Noun 05, the star angle difference. This is Apollo Control at 2 hours, 8 minutes into the mission. One instance of this prompts McCandless to think that the crew were calling. Astronauts report it feels good. July 17 marks Day 2, the day of the launch. It hasn't gone quite as expected. This is Apollo Control at 102 hours, 12 minutes into the flight of Apollo 11. 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. This is required because only one horizon will be visible depending on which side of the planet is illuminated by the Sun. Liftoff! That reading was the difference in pressure between the Lunar Module cabin and the Command Module cabin. Europe in on the left with the Mediterranean Sea and western Sahara Further right. This is Apollo Control. North is approximately up with the Greenland icecap visible. Aldrin and Mission Control are essentially comparing readings of the same parameter. 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. From these sightings, he determines how far the platform has drifted since the last P52 15 hours ago. Finally, if you are a true NASA space nut…you can DOWNLOAD the … 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. Day 5 . The crew of Apollo 11 is in the rest period. EAGLE Looking good. Some 51 minutes remaining in the scheduled sleep period for the crew of Apollo 11. Voici 11 anecdotes surprenantes sur la mission Apollo 11. When Mike attempted to carry out a navigation exercise before their sleep period, it didn't go too well. startxref It was set to the value of Delta-V. It’s available in 4K and HDR and is one of the most amazing films I’ve ever seen. 0000005686 00000 n And Bruce McCandless is back on the CapCom console now. The Guidance Officer reports Apollo 11 is now in the attitude for the midcourse correction. xref That's Jim Lovell, the commander of the backup Apollo 11 crew communicating with Apollo 11 at the present time. 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. It focuses on the 1969 Apollo 11 mission, the first spaceflight from which men walked on the Moon. Image by LPI, AS11-36-5354 - Earth at about 181,000 km or 98,000 nautical miles. 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, AS11-36-5360 - Earth at about 210,000 km or 113,500 nautical miles. North is right and the African continent is prominent. CAPCOM 11, Houston, the definition is pretty good on our monitor here. As they manoeuvre, the signal from the spacecraft weakens and becomes noisier. Image by LPI, AS11-36-5357 - Earth at about 205,000 km or 111,000 nautical miles. The flight was part of the Space Race. 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. 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. To take the PAO's explanation further, star 40 is Altair (Alpha Aquilae). Twenty seconds and counting. This is the Delta-V counter mounted on the EMS panel. 0000006560 00000 n Image by LPI. The sextant's arrangement has a fixed line of sight which can be rotated 360° around a shaft, giving the shaft angle. If the valve is in any other position, then the gauge reading is meaningless. It appeared in many prominent publications, including on the cover of the best-selling Penguin paperback. This dish antenna can automatically track a ground station by sensing when it is going slightly off track. Star 37 is Nunki. 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. North is left with the Greenland icecap visible. AS11-36-5352 - 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. 0 The values he will come up with, in Noun 93, are -0.493° in X, -0.191° in Y and -0.024° in Z. 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. Apollo 11 about to be acquired at the Tananarive station. The Atlantic Ocean dominates the view with the South American continent at the lower part of the globe. trailer The backup Lunar Module Pilot Fred Haise is also in the Control Center at the present time. That was a good burn. 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. 0000001321 00000 n 12, 11, 10, 9 ... ignition sequence start ... 6, 5, 4, 3, 2, 1, 0 ... All engines running. Also visible are Arabia, Asia and Europe, particularly Spain. Neil has the LM holding its attitude using the AGS. TM is short for telemetry. Image by LPI. Day 2 . Image by LPI. 0000000716 00000 n 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. The Atlantic Ocean dominates the view with the South American continent at the lower part of the globe. 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. Also visible are Arabia, Asia and Europe, particularly Spain. 0000001637 00000 n 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). h�b```b``�``a`����ˀ �@1V �� �02. Noun 87 presents the optics calibration data. 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. 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 clip is kindly donated by Mark Gray. Star 01 is Alpheratz (Alpha Andromedae). Image measurement and triangulation suggests that two photographs are taken around this time. 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. Make sure to watch APOLLO 11 directed/edited by Todd Miller for the most immersive experience that covers the entire 9-day journey. Velocity 5,256 feet per second [1,602 m/s]. The specular reflection of the Sun off the ocean surface is a phenomenon that artists depicting Earth prior to the Moon flights usually failed to portray. 0000004003 00000 n 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. That was Buzz Aldrin giving the description of what he could see on the Earth. North is right and the African continent is prominent. Spain and western Sahara are near the terminator. 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. Apollo 11 is presently 127,991 nautical miles [237,039 km] from Earth, traveling at a speed of about 4,400 feet per second [about 1,340 m/s]. We are showing an orbit now of 107 by 105.7 nautical miles and an orbital period of 1 hour, 28 minutes, 30 seconds. This is Apollo Control at 139 hours. CAPCOM Roger. Image by LPI, AS11-36-5353 - Earth at about 181,000 km or 98,000 nautical miles. As the spacecraft revolves, the crew can maintain communication by manually selecting whichever Omni is facing Earth. 11 anecdotes surprenantes sur Apollo 11. Il y a 47 ans tout pile, le 20 juillet 1969, l'Homme a pour la première fois marché sur la Lune. Postmarked way back in 1969, 50 years on, these incredibly nostalgic original First Day Covers are now very hard to find. 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. T-15 seconds, guidance is internal. CAPCOM Roger. 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. 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. North is approximately up with the Greenland icecap visible. 0000010147 00000 n EAGLE The Eagle has wings. At the present time, Apollo 11 is 178,236 nautical miles [330,093 km] from Earth, and the velocity has dropped down now to 3,146 feet per second [959 m/s]. Also visible are Arabia, Asia and Europe, particularly Spain. This is Apollo Control. 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. 0000001189 00000 n Doctor Aviation recaps the week. 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. The normal range for combustion pressure (i.e. JULY 17, 1969. <<5ED51F7B7E301344B525CE92AF90E89F>]/Prev 56751/XRefStm 989>> Those figures are not based on the proper Ground Elapsed Time. Belay that last announcement. 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.
