Zitat Apollo in Real Time is an interactive, multimedia website that presents the Apollo 11, Apollo 13, and Apollo 17 missions as they happened at the time by compiling and synchronizing thousands of hours of audio and video recordings, transcripts, and photographs. Apollo historian Ben Feist created the Apollo 11 and Apollo 17 real-time sites, and was a NASA contractor by the time he created the Apollo 13 real-time site. Air & Space magazine describes the Apollo 13 site as "one of the most ambitious multimedia history sites ever created".[1]
Each of the real-time sites is fronted by a dashboard that provides options for different audio and video channels. Viewers can explore the multimedia properties, search the transcript, or experience the in-progress feed.[2] Each media element is synchronized precisely (or as close as possible) to the actual mission time's master clock, Ground Elapsed Time.
The Apollo 17 project, which Feist began in 2009 and launched six years later[3] as a part-time hobby, was the first real-time site published. It includes raw audio from the onboard voice and air-to-ground communication channels in Mission Control that had been released by NASA, and film that had been collected by archivist Stephen Slater in the UK.[1] Apollo 17 in real-time contains 300 hours of audio, 22 hours of video, and 4200 photographs.[5] The alpha version of the Apollo 17 site was released in March, 2015,[6] and a reworked final version was released for the 43rd anniversary of Apollo 17 in December, 2015.[7] For the 44th anniversary, additional content was added, including 3D renderings of Lunar Roving Vehicle traverses using data from the Goddard Space Flight Center.[8]

Zitat 010:29:37 Public Affairs This is Apollo Control at 10 hours 29 minutes. Apollo 17 now, 48,070 nautical miles from Earth, velocity 8,434 feet per second. Pete Frank and the orange team of flight controllers getting ready to hand over to Gerry Griffin and his gold team of flight controllers at this time. Astronaut Bob Parker will remain as the CAPCOM for a good deal of this next shift. Several spurious master alarms that were seen while the spacecraft was still in Earth orbit are as yet unexplained. There are no obvious reasons for them. The spacecraft experts in the back rooms, the support rooms here at the Mission Control Center are still tracking this situation. It's not considered a serious problem. The more recent master alarms that have occurred during this shift and during the translunar coast phase after Apollo 17 burned translunar insertion, are attributed to a higher than normal oxygen flow at regular intervals in the cabin. The cabin is still being purged of the partial nitrogen atmosphere that it contained at launch that is being purged, a vent valve is open in the cabin and the higher than normal O2-rate has been introduced to help purge the cabin. Now, added to that when the water accumulator in the suit circuit cycles, there is a brief increase of oxygen flow over and above the higher than normal flow that we are using to purge the cabin. And this is just high enough to when the water accumulator cycles it brings it up just high enough to trigger the master alarm. It is not a problem. The last three or four master alarms that we have seen are attributed to this. However, the Earth orbit master alarms are not yet accounted for. But, they are not considered to be a serious problem. During this shift a midcourse correction number 1 was performed on the SIV-B stage of the launch vehicle, 13 feet per second performed with the auxilary propulsion system. A second midcourse for that third stage of launch vehicle is planned at a Ground Elapsed Time of 11 hours 15 minutes. The magnitude of the burn is not - is not yet known. These midcourses are to tune up the trajectory of that stage, to bring it closer to the desired impact point on the lunar surface. As far as the spacecraft is concerned midcourse correction number 1 was passed. We did not perform midcourse correction number 1. The magnitude at that time was less than 3 feet per second. We will probably perform a midcourse correction number 2 at 35 hours and 30 minutes. A preliminary look at that indicates about a 10-1/2 foot per second burn at that time. The Mission is going well. We have not heard from the crew for some time now and are confident that they are asleep. The spacecraft is in passive thermal-contro1 mode, stabilized in 1 revolution every 18 minutes, approximately 3 per hour. The crew is scheduled to be awakened 4 hours, 24 minutes from this time. At 10 hours 35 minutes into the Mission, this is Mission Control, Houston.

Zitat Orion into final critical in-flight test as reentry and splashdown arrive written by Chris Gebhardt December 11, 2022
The Orion spacecraft is nearing the end of its flight on the Artemis I mission, with a splashdown in the Pacific Ocean off the Baja Coast near Guadalupe Island targeted for 12:39 PM EST (17:39 UTC) on Sunday, Dec. 11.
Final in-flight development test objectives were completed on Saturday, Dec. 10, and the fifth and penultimate return trajectory correction burn was executed to continue aligning the spacecraft for its reentry into Earth’s atmosphere at the right angle to land at the intended location.
The sixth and final return trajectory maneuver was then completed Sunday morning approximately five hours before splashdown. By this point, communications with Orion had switched from the Deep Space Network to NASA’s geostationary orbit-located Tracking and Data Relay Satellite (TDRS) network.
To safely enter the Earth’s atmosphere, Orion must first discard its European Service Module — which in addition to providing propulsion, attitude control, life support, power, and several other critical elements for the mission, has also protected Orion’s all-important heatshield.
The overall finale to Orion’s first lunar mission will be a test of alterations made to the way the capsule’s heatshield is fabricated.
Following lessons learned from the Exploration Flight Test 1 (EFT-1) mission, for which that Orion capsule’s heatshield was one large piece, the new heatshield design is produced in segments and then combined to form a singular unit.
Overall, the heatshield is comprised of approximately 180 Avcoat ablator tiles between 2.5 and 7.5 cm (one to three inches) thick. These are capable of protecting the capsule from the 2,760 degrees C (5,000 degrees F) temperatures it will experience as it performs its reentry into the atmosphere at nearly 40,000 km/h (25,000 mph).
Another ablator material is also used in other locations. Called 3DMAT, the 3-Dimensional Multifunctional Ablative Thermal Protection System is made of woven quartz in resin and is used to strengthen various “connection points along the spacecraft,” according to NASA.
After the skip profile (where Orion will dip into the atmosphere, arc back up, and then descend back down) and plasma stages of reentry, the parachute and recovery systems will then be put to the test.
“Then we jettison the forward bay cover that protects all of our parachutes during the mission,” said Hawes of Lockheed Martin. “Then they (the recovery team) will track the deployment of the multiple sets of parachutes.”
Once aboard the recovery ship, Orion will be brought back to the Port of San Diego for final preparations for a quick shipment back to the Kennedy Space Center for post-flight deserving to reduce the hazards from the capsule’s onboard, stored propellants leftover from the mission.

Die Schlauchboote der Navy werden sich noch nicht gelich der Kapsel nähern. Es wird noch auf das vollständige Verdunsten des Ammoniak-Vorrats gewartet, den das Raumschiff an Bord hat, um das Kapselinnere während des Flugs zu kühlen.

Was hat es mit dem Rauch-/Nebelschwaden auf sich, die da gelegentlich übers Wasser wabern?

Das sind Rauchmelder/schwimmende Nebelerzeuger, mit denen die Bergungstrupps alles markieren, was zum Raumschiff gehört und auf dem Wasser treibt - vor allem die Fallschirme, aber auch die Abdeckkappen. Das soll alles eingesammelt und untersucht werden. Und sie markieren die Bereiche, in denen das schwimmt. Die werden "footprints" genannt. Das team, das dafür zuständig ist, heißt, ganz offiziell, das "Sasquatch Team" (wg "bigfoot"). Es handelt sich um insgesamt 26 Bereiche.
