Artemis

The crew module of NASA’s Orion spacecraft has successfully separated from its service module at 11:00 a.m. CST in preparation for the crew module’s return to Earth. The service module will burn up harmlessly in Earth’s atmosphere upon re-entry over the Pacific Ocean. The Artemis I trajectory is designed to ensure any remaining parts do not pose a hazard to land, people, or shipping lanes.

Next, the crew module will perform a skip entry technique, dipping into the upper part of Earth’s atmosphere and using that atmosphere, along with the lift of the capsule, to skip back out of the atmosphere, then reenter for final descent under parachutes and splash down. This technique enables the spacecraft to accurately and consistently splash down at the selected landing site for Artemis missions regardless of when and where they return from the Moon. During re-entry, the enormous heat generated as Orion encounters the atmosphere turns the air surrounding the capsule into plasma, which will briefly disrupt communications with the spacecraft.

Below are the upcoming re-entry milestones in CST:

11:20:14 p.m. – Crew Module Entry Interface
11:35:28 p.m. – Altitude 40,000 feet
11:36:02 p.m. – Forward Bay Cover Chute Deploy
11:36:06 p.m. – Drogue Chute Deploy
11:37:26 p.m. – Main Chute Deploy
11:39:41 p.m. – Splashdown

Earth’s atmosphere initially will slow the spacecraft to 325 mph, then the parachutes will slow Orion to a safe splashdown speed of 20 mph or less as it descends through Earth’s atmosphere. Parachute deployment begins at an altitude of about five miles with three small parachutes pulling the forward bay covers away. Once the forward bay cover separates, two drogue parachutes will slow and stabilize the crew module for main parachute deployment. At an altitude of 9,500 feet and a spacecraft speed of 130 mph, three pilot parachutes will lift and deploy the main parachutes to slow Orion to a landing speed that ensures astronaut safety for crewed missions.

When Orion splashes down, the crew module uprighting system, also known as CMUS, deploys a series of five bright-orange helium-filled bags on the top of the capsule to upright the capsule in the event it stabilizes upside down. The system will deploy regardless of the landing position of the capsule, and it takes less than four minutes to upright the capsule if needed. The capsule must be upright for crew module communication systems to operate correctly and to help protect the health of the crew members inside on future missions.

At 12:40 p.m. EST, Dec. 11, 2022, NASA’s Orion spacecraft for the Artemis I mission splashed down in the Pacific Ocean after a 25.5 day mission to the Moon. Orion will be recovered by NASA’s Landing and Recovery team, U.S. Navy and Department of Defense partners aboard the USS Portland ship. Credit: NASA/Kim ShiflettNASA’s Orion spacecraft successfully completed a parachute-assisted splashdown in the Pacific Ocean at 9:40 PST, 12:40 EST as the final major milestone of the Artemis I mission. Engineers will perform several additional tests while Orion is in the water and before powering down the spacecraft and handing it over to the recovery team aboard the USS Portland.

At the direction of the NASA recovery director, Navy divers and other team members in several inflatable boats will approach the spacecraft. When Orion is ready to be pulled into the ship’s well deck at the waterline, the divers will attach a cable, called the winch line, to pull the spacecraft into the ship and up to four additional tending lines to attach points on the crew module. The winch will pull Orion into a specially designed cradle inside the ship’s well deck and the other lines will control the motion of the spacecraft. Once Orion is positioned above the cradle assembly, technicians will drain the well deck and secure it on the cradle.

Once aboard the vessel, teams will take the spacecraft to U.S. Naval Base San Diego and soon return it to NASA’s Kennedy Space Center for inspection. Technicians in Florida will thoroughly inspect Orion, retrieving data recorded on board, removing onboard payloads, and more.

Artemis I was the first integrated test of NASA’s deep space exploration systems – the Orion spacecraft, SLS rocket, and the supporting ground systems – and the first in a series of increasingly complex missions at the Moon. Through Artemis missions, NASA will establish a long-term lunar presence for scientific discovery and prepare for human missions to Mars.

NASA will host a post-splashdown news conference is targeted for 3:30 p.m. EST

Participants include:

Bill Nelson, NASA administrator
Jim Free, NASA associate administrator for the Exploration System Development Mission Directorate, NASA Headquarters
Vanessa Wyche, director, Johnson
Janet Petro, director, Kennedy
Mike Sarafin, mission manager, NASA Headquarters
Howard Hu, Orion Program manager, Johnson

The Orion spacecraft has been secured in the well deck of the USS Portland. The ship will soon begin its trip back to U.S. Naval Base San Diego, where engineers will remove Orion from the ship in preparation for transport back to Kennedy Space Center in Florida for post-flight analysis.

Upon Orion’s successful splashdown in the Pacific Ocean west of Baja California at 9:40 PST/12:40 EST Dec. 11, flight controllers in mission control at NASA’s Johnson Space Center in Houston spent about two hours performing tests in open water to gather additional data about the spacecraft, including on its thermal properties after enduring the searing heat of re-entry through Earth’s atmosphere. Recovery personnel also spent time collecting detailed imagery of the spacecraft before beginning to pull the capsule into the USS Portland’s well deck.

The recovery process involved divers attaching a cable called a winch line and several additional tending lines attached to the crew module. The winch was used to pull Orion into a specially designed cradle inside the ship’s well deck and the other lines were used to control the motion of the spacecraft. The recovery team consists of personnel and assets from the U.S. Department of Defense, including Navy amphibious specialists and Space Force weather specialists, and engineers and technicians from Kennedy Space Center in Florida, Johnson Space Center in Houston, and Lockheed Martin Space Operations.

Orion is expected to arrive to shore Dec. 13 with offload expected on Dec. 15.

Team members with NASA’s Exploration Ground Systems program successfully removed the Artemis I Orion spacecraft from the USS Portland Dec. 14, after the ship arrived at U.S. Naval Base San Diego.

Team members with NASA’s Exploration Ground Systems program successfully removed the Artemis I Orion spacecraft from the USS Portland Dec. 14, after the ship arrived at U.S. Naval Base San Diego a day earlier. The spacecraft successfully splashed down Dec. 11 in the Pacific Ocean west of Baja California after completing a 1.4 million-mile journey beyond the Moon and back, and was recovered by NASA’s Landing and Recovery team and personnel from the Department of Defense.

Engineers will conduct inspections around the spacecraft’s windows before installing hard covers and deflating the five airbags on the crew module uprighting system in preparation for the final leg of Orion’s journey over land. It will be loaded on a truck and transported back to the agency’s Kennedy Space Center in Florida for post-flight analysis.

Before its departure, teams will open Orion’s hatch as part of preparations for the trip to Kennedy and remove the Biology Experiment-1 payload which flew onboard Orion. The experiment involves using plant seeds, fungi, yeast, and algae to study the effects of space radiation before sending humans to the Moon and, eventually, to Mars. Removing the payload prior to Orion’s return to Kennedy allows scientists to begin their analysis before the samples begin to degrade.

Once it arrives to Kennedy, Orion will be delivered to the Multi-Payload Processing Facility where additional payloads will be taken out, its heat shield and other elements will be removed for analysis, and remaining hazards will be offloaded.

Artemis

The Artemis I Orion spacecraft is on its way back to NASA’s Kennedy Space Center in Florida.  After completing a 25.5-day, 1.4-million-mile journey beyond the Moon and back Dec. 11, the spacecraft was recovered from the Pacific Ocean and transported to U.S. Naval Base San Diego, where engineers prepared the spacecraft for its trek by truck to Kennedy. Orion is scheduled to arrive to Kennedy’s Multi Payload Processing Facility by the end of the year. 

Once at Kennedy, technicians will open the hatch and unload several payloads, including Commander Moonikin Campos, zero-gravity indicator Snoopy, and the official flight kit as part of de-servicing operations. In addition to removing the payloads, Orion’s heat shield and other elements will be removed for analysis, and remaining hazards will be offloaded. 

NASA also has released new aerial footage of Orion’s descent through the clouds and splashdown taken from an Unmanned Aircraft System or drone. View the new imagery of spacecraft’s return to Earth here.

NASA’s CAPSTONE – short for Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment – is in good health following a communications issue that began in late January, and the mission team is preparing for upcoming technology demonstration tests.

Beginning Jan. 26, CAPSTONE was unable to receive commands from ground operators. The spacecraft remained overall healthy and on-course throughout the issue, sending telemetry data back to Earth. On Feb. 6, an automatic command-loss timer rebooted CAPSTONE, clearing the issue and restoring two-way communication between CAPSTONE and the ground.

The CAPSTONE team, led by Advanced Space, is now preparing for continued testing of the spacecraft’s Cislunar Autonomous Positioning System, or CAPS, and other technology demonstrations.

CAPS is a navigation technology developed by Advanced Space that uses data between two or more spacecraft to pinpoint a satellite’s location in space. The test will involve two spacecraft: CAPSTONE and NASA’s Lunar Reconnaissance Orbiter (LRO). Following interface testing with LRO’s ground systems, the CAPSTONE team attempted to gather crosslink measurements in mid-January. During this test, LRO received a signal from CAPSTONE, but CAPSTONE did not collect crosslink ranging measurements from the returned signal. These results will help improve additional CAPS tests over the coming weeks.

The team is also preparing for the mission’s other technology demonstrations, including a new CAPS data type that will use one-way uplink measurements enabled by the spacecraft’s Chip Scale Atomic Clock.

Since arriving to orbit on Nov. 13, CAPSTONE has completed more than 12 orbits in its near-rectilinear halo orbit (NRHO) – the same orbit for Gateway – surpassing one of the mission’s objectives to achieve at least six orbits. The mission team has performed two orbit maintenance maneuvers in this time. These maneuvers were originally scheduled to happen once per orbit, but the mission team was able to reduce the frequency while maintaining the correct orbit. This reduces risk and complexity for the mission and informs plans for future spacecraft flying in this orbit, like Gateway.

CAPSTONE is owned by Advanced Space and the spacecraft was designed and built by Terran Orbital. Operations are performed jointly by teams at Advanced Space and Terran Orbital. The mission is funded by the Small Spacecraft Technology Program in NASA’s Space Technology Mission Directorate.

Artemis

With the success of NASA’s Artemis I launch, the previously unexplored shadowy regions near the lunar South Pole where Artemis astronauts will land in 2025, are more within our reach than ever before.

One instrument that will support these future lunar exploration efforts is a hypersensitive optical camera called ShadowCam. ShadowCam is one of six instruments on board the Korean Aerospace Research Institute (KARI)’s Korea Pathfinder Lunar Orbiter, known as Danuri, which launched in August 2022 and entered lunar orbit last December.

Previous cameras in lunar orbit were designed to acquire images of sunlit surfaces. Developed by Malin Space Science Systems and Arizona State University, ShadowCam’s primary function is to collect images within permanently shadowed regions near the lunar poles. These areas never receive direct sunlight and are thought to contain water ice – a significant resource for exploration that can be used as fuel or oxygen and for other habitation applications.

Building on cameras developed for NASA’s Lunar Reconnaissance Orbiter, ShadowCam is 200 times more light-sensitive and is therefore able to capture detailed images within permanently shadowed regions – even in the absence of direct light – by using the light that is reflected off nearby geologic features such as mountains or the walls of craters. Images of the permanently shadowed wall and floor of Shackleton Crater captured by Lunar Reconnaissance Orbiter Camera (LROC) (left) and ShadowCam (right). Each panel shows an area that is 5,906 feet (1,800 meters) wide and 7,218 feet (2,200 meters) tall. Image Credit: NASA/KARI/ASU

In addition to mapping the light reflected by permanently shadowed regions to search for evidence of ice deposits, ShadowCam will also observe seasonal changes and measure the terrain inside the craters, all in service of science and future lunar exploration efforts. The high-resolution images could help scientists learn more about how the Moon has evolved, how water is trapped and preserved in PSRs, and could help inform site selection and exploration planning for Artemis missions.

Since Danuri entered lunar orbit, ShadowCam has been in an operational checkout period, during which it has been collecting dozens of images of the lunar polar regions, including an image of Shackleton Crater, to calibrate and test its functionality. Following this checkout period, which will conclude later this month, ShadowCam will start its campaign to capture images of shadowed terrain as Danuri routinely passes over them during the planned mission of 11 months.

Erstaunlich, das selbst die Spuren eines an den Kraterwänden des Shackleton Kraters hinab rollenden 5m Brockens zu erkennen sind. Die Lichtausbeute ist unglaublich.

Wau!

Das Ei des Kolumbus! Daß man nicht vorher auf die Idee kam (oder hat es einfach nicht interessiert).

Sind wir Mondbeobachter doch schon lange fasziniert von aus der Dunkelheit langsam über Stunden auftauchenden Zentralbergspitzen, gegenüber liegenden Kraterwänden etc.

Die müssen doch, absolut gesehen - jede Menge Licht in die noch nicht von der Sonne beschienenden Innenbereiche der Krater hineinfluten, oder jenseits der Krater (vom nächsten hellen Kraterrand). Man muss eben die Kameras/Belichtungszeiten auf dieses indirekte Licht auslegen...genug Licht liefern sie ja.

Ich bin sicher, Astronauten die da im Krater arbeiten, würden gut sehen können wenn auch nur eine kleine Bergspitze oder Kraterrandspitze vom Sonnenlicht hell erleuchtet ist.

Hallo Walter, ich bin nicht sicher ob man im Krater etwas sehen könnte. Auf den Bildern der Apollo Astronauten, davon hab ich zwei Bücher, sind die Schatten wegen des fehlenden Streulicht im Vakuum des Alls , alle schwarz. Ich bin aber sicher die auftauchenden hellen Bergspitzen oder Kraterwände sind aus der Perspektive sehr beeindruckend.

Technicians at NASA’s Kennedy Space Center in Florida operate a 30-ton crane to lift and transfer the Orion spacecraft’s service module into the FAST (final assembly and system testing) cell on May 22, 2023, inside the spaceport’s Neil A. Armstrong Operations and Checkout Building.

Teams are performing final checkouts of the Orion spacecraft’s service module before integrating the crew and service modules for Artemis II, the first Artemis mission with crew. In parallel, technicians from Airbus will conduct inspections of the solar array wings following the successful completion of service module acoustic testing in May, which ensured the service module can withstand the speed and vibration it will experience during launch and throughout the mission. During the inspections, each of the four panels will be fully redeployed and reexamined. The crew module also will undergo acoustic testing ahead of joining with the service module.

Provided by ESA (European Space Agency), the service module is the powerhouse that will fuel, propel, and provide in-space maneuvering capability, and is responsible for life support commodities such as water and breathable air for astronauts onboard Orion in support of future Artemis missions.

On June 25, 2023, teams completed installation of the heat shield for the Artemis II Orion spacecraft inside the high bay of the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida.

The 16.5-foot-wide heat shield is one of the most important systems on the Orion spacecraft ensuring a safe return of the astronauts on board. As the spacecraft returns to Earth following its mission around the Moon, it will be traveling at speeds of about 25,000 mph and experience outside temperatures of nearly 5,000 degrees Fahrenheit. Inside the spacecraft, however, astronauts will experience a much more comfortable temperature in the mid-70s thanks to Orion’s thermal protection system.

Up next, the spacecraft will be outfitted with some of its external panels ahead of acoustic testing later this summer. These tests will validate the crew module can withstand the vibrations it will experience throughout the Artemis II mission, during launch, flight, and landing.

Once acoustic testing is complete, technicians will attach the crew module to Orion’s service module, marking a major milestone for the Artemis II mission, the first mission with astronauts under Artemis that will test and check out all of Orion’s systems needed for future crewed missions.

AstroService Was ist im Kontext der heutigen Statusmeldung zur Artemis II Mission unter dem "acoustic testing" des Crew Moduls zu verstehen?

Zitat von Freddi

Was ist im Kontext der heutigen Statusmeldung zur Artemis II Mission unter dem "acoustic testing" des Crew Moduls zu verstehen?

Beim "acoustic testing" des Crew-Moduls der Artemis II Mission handelt es sich um einen Test, bei dem das Modul extremen Schallbelastungen ausgesetzt wird. Dies geschieht, um sicherzustellen, dass es den lauten Geräuschen standhalten kann, die beim Start und während des Fluges auftreten. Beim Start erzeugen die Triebwerke eines Raumschiffs enorme Schallwellen, die eine potenzielle Gefahr für die Astronauten und die Struktur des Moduls darstellen können. Daher ist es wichtig, dass das Crew-Modul robust genug ist, um diesen Belastungen standzuhalten. Das acoustic testing hilft den Ingenieuren, mögliche Schwachstellen im Design zu identifizieren und entsprechende Anpassungen vorzunehmen, um die Sicherheit der Astronauten zu gewährleisten.

Mobile launcher 1 is on its way to Launch Pad 39B at NASA’s Kennedy Space Center in Florida to prepare for Artemis ll, the first crewed mission on the agency’s path to establishing a long-term presence at the Moon under Artemis. The ground structure began its trek from the west park site at approximately 8:27 a.m. EDT on Aug.16 atop the crawler-transporter 2. It will stop at the gate of pad 39B and resume its journey on Aug. 17.

At 380 feet tall, the mobile launcher is used to assemble, process, and launch NASA’s SLS (Space Launch System) rocket and Orion spacecraft. It contains all of the connection lines – known as umbilicals – and ground support equipment that will provide the rocket and spacecraft with the power, communications, fuel and coolant necessary for launch.

Once the mobile launcher is at the launch pad, teams with NASA’s Exploration Ground Systems Program will conduct a series of tests and continue ground systems upgrades for both the mobile launcher 1 and the launch pad. These preparations will range from a launch day demonstration for the crew, closeout crew, and the pad rescue team to rehearse operations to testing the emergency egress system and the new liquid hydrogen sphere.
