Artemis I, new images of the moon and developments a week after the mission

It’s now been over a week since the Artemis I mission departed and it’s time to take stock of what’s happened in the past few hours. The Orion spacecraft is now on its seventh day of travel and as has been stated many times, the main goal of the mission is to perform a test flight around the Moon, without landing, but thus paving the way for having future astronauts on board. But first there must be certainty that the primary systems and backup solutions are working perfectly, because When human lives are at stake, the margin for error must be kept to a minimum.

At the moment, there were no hitches and everything is going according to plan, so before viewing the latest photos, let’s find out about the most interesting developments.

First of all, NASA mentioned that during the past day, when it was 07:02 AM here, Orion has completed its fifth course correction, which ignited the ESU’s auxiliary engines for 5.9 seconds, accelerating Orion by just under 1 meter per second. The R-4D-11 auxiliary engines are nothing more than a variant of the original R-4D, those used on the Apollo program lunar missions.

Arranged in this case in the lower part of the service unit, they are divided into four groups of two groups each capable of providing about 45 kg of thrust, useful for maneuvers that require great precision in the dose of energy. In total, the Orion service module contains 33 engines of various sizes, which provide the thrust necessary for the spacecraft to perform one or two orbits around the Moon (only once on this test mission) and return to Earth.

while The NASA flight control room team continued testing the spacecraft’s star trackers To determine their sensitivity to thermal changes as part of the planned tests, engineers used an optical navigation system to collect additional images of the moon. Operations had already begun on the fifth day of the mission, and for starters, star trackers are a navigational instrument that measures the positions of stars to help the spacecraft determine its bearing. During the pre-flight days, engineers evaluated the raw data to understand star tracker readings related to the missile launch.

Meanwhile, on the sixth day of the mission, NASA released a video showing the Earth’s elevation from the Orion spacecraft’s view. A short clip but definitely great, and we suggest watching it.

The Star Tracker The optical navigation system is part of Orion’s advanced guidance, navigation and control system, thanks to which NASA can know exactly where the spacecraft is in space, direction and direction taken. In particular, optical navigation has an important function for a backup solution, i.e. able to guarantee a safe journey home in case of loss of communications. Given that the mission works specifically to test every safety technology installed on board, flight controllers have in the past few hours put the SAT mode to the test, which is based on an algorithm designed to restore and maintain communications with Earth in the event Orion suffers a temporary power outage, causing It restarted the Orion.

This morning, when it was 05:31 with us, Orion has left the lunar field of influence and will continue moving towards its next goal, namely entering a retrograde orbit on November 25th. Just before entering orbit, Orion will be approximately 92,000 km from the Moon at its farthest point from the lunar surface during the mission, while on Saturday, November 26, Orion will surpass the record set by Apollo 13 for the farthest distance traveled by a spacecraft. Human designed space. It is preset to 400,171 km, but Orion is expected to reach an incredible distance of 432,199 km.

In the meantime, new pics of solar panel-mounted cameras have arrived, like the one we’re offering uncut. The photo was taken one day after the flyby of the moon.

Then there’s the gorgeous image captured by the Argomoon, a cube-type satellite made by the Italian company Argotec. In the following image, we can see the hidden side of the moon, specifically the region known as the East Sea.

We can see how the least protected part of our satellite was literally affected by the impacts of meteorites, because it is the most exposed to space.

At this point we just have to wait for further developments in the mission, which of course we will not fail to inform you about in the coming days as soon as NASA makes them available.

In the meantime, we remind you that the Mars Perseverance mission is also going at full speed and that the rover has recently identified an area of ‚Äč‚Äčinterest for a potential collection of new samples. But there is also news about the Mars Sample Return Mission and for Creativity! More details in our special post published a few days ago.
