making history. Orion has landed after a mission that we have not seen since Apollo

April 11, 2026 by usatoday24

Artemis II already had a place in history assured before it even hit the water, but its closure gives the mission a different dimension. Orion has splashed down off the coast of San Diego (United States) and with this has culminated a ten-day trip that has returned astronauts to the vicinity of the Moon for the first time since 1972. What we have seen has not only been a round trip flight around our satellite, but also the validation in real conditions of a ship, a crew and a roadmap with which NASA and its international partners want to go further than ever. The key moment has arrived at 8:07 p.m. EDT on April 10, equivalent to 2:07 a.m. on April 11 in Spanish peninsular time. With this splashdown, Orion’s flight sequence is closed and a less visible, but equally measured phase begins: recovery in the ocean. We are not just talking about a capsule touching the water, but about the point at which a maneuver calculated to the minute gives way to helicopters, military means, medical checks and transfer of the crew out of the vehicle. Artemis II has made history: the most difficult return culminates over the Pacific The most delicate part was not the lunar flyby, but the return home. To return safely, Orion had to enter the atmosphere under the right conditions, with heat shield exposed after separating from the service module and prepared to withstand extreme conditions: intense friction, plasma around the capsule and a communications outage expected for six minutes. NASA had further explained that, in a nominal profile, the crew could withstand up to 3.9 G. Everything in this phase depended on physics, engineering and timing being exactly where they needed to be. The US space agency communicated this sequence in EDT time, but to better follow the outcome from Spain it is advisable to transfer it to peninsular time, where everything happened already in the early morning of April 11. 01:33: service module separation and heat shield exposure (completed) 01:37: final adjustment of entry path (completed) 01:53: start of upper atmosphere re-entry and start of communications blackout (completed) 02:03: opening of drogue parachutes at high altitude (filled) 02:04: deployment of three main parachutes to reduce descent speed (completed) 02:07: Orion splashdown off San Diego (completed) Before 04:07: crew recovery and transfer to support ship (earring) As we say, from this moment on the recovery device that NASA has deployed together with US military personnel off the coast of California comes into play. According to the sequence planned by the agency, the crew must be extracted from the capsule and transferred by helicopter to the USS John P. Murtha, where the first medical evaluations after ten days of mission. If we look at the mission as a whole, Artemis II leaves several well-defined milestones. It was the first manned flight beyond Earth’s orbit since 1972, it completed a lunar flyby without landing on the moon and established a new distance record for humans by exceeding 400,000 kilometers from Earth, above the Apollo 13 mark. In between so much hard data, Artemis II has also left small scenes capable of becoming fixed in the collective memory. There are the images of the hidden side of the Moon taken by the crewcaptures of a solar eclipse or video calls from deep space. And then there is the most unexpected detail of all, the one that gave the mission a touch of color in the middle of the institutional solemnity: a jar of Nutella appearing floating in the ship during one of the broadcasts. What comes next helps you better measure what you just finished. NASA now faces a demanding calendar phase for the next stages of the Artemis program, with a new mission already in preparation and with the focus on the operations that must support a future lunar landing. The next test will seek to advance that architecture with new maneuvers and tests before taking the next leap. When the images of the landing, the parachutes and the recovery in the Pacific pass, what will remain will be something much more profound than a postcard of the return. Artemis II will have shown that it is possible send astronauts back to the lunar environmentbring them back and successfully complete the most demanding part of the flight.

Artemis II will make the Apollo that took us to the Moon look like a space slum: it will even have a private toilet

March 31, 2026 by usatoday24

If all goes well, Artemis II It could be launched on April 1 towards the Moon. It will be the first time that a manned spacecraft travels to our satellite in more than 50 years and, although this time there will be no moon landing, the capsule with 4 astronauts on board will make a lunar flyby, which will be the highlight of a 10-day space trip. A week and a half during which, logically, the crew will have to clean up and relieve themselves. But how do you go to the bathroom in space? Luckily, the capsule will have a comfort that they didn’t have in the Apollo program. A toilet. The complicated mission of going to the bathroom. From Apollo 10, in 1969, until Apollo 17, in 1972there were a total of 12 astronauts who traveled to the Moon. At that time, her only toiletries were a few wet wipes. to urinate They used devices similar to condoms that were changed daily. When it was time to evacuate, they were connected to a bag, with a kind of hose. It was not a very efficient system and there were often leaks. There was also no system adapted to the female anatomy, since all the astronauts were men. The greater waters. As for feces, a bag was used that stuck to the buttocks. Something quite similar to a diaper, but with a compartment to put your hands in and use toilet paper. Again, there could be leaks. In fact, there is a transcript of an astronaut from Apollo 10 in which he asked for a napkin to pick up a fragment of feces that was floating in the air. Once caught (sometimes literally), the bags were saved and stored for analysis on land. Added to all this is that the astronauts did not have the slightest privacy to go to the bathroom in space. The experience, and especially the smell, could not have been pleasant at all. The urine collection system of the Apollo missions was very rudimentary. Opportunity cost. Whether it is for personal hygiene or for urinating or defecating, going to the bathroom in space involves two major complications. On the one hand, microgravity prevents what should fall under its own weight from doing so. We return to the problem of floating feces from Apollo 10. On the other hand, water is needed. Transporting sufficient quantities of water into space would place excess load on spacecraft. Furthermore, precisely because of microgravity, it would move freely, so that some of the many devices that exist in the small space of a capsule like the Orion of Artemis II could get wet and damaged. For this reason, the use of water is reduced to a minimum and methods are sought to overcome microgravity as much as possible. Artemis II’s toilet. In Artemis II the astronauts They will use liquid soap and leave-in shampooas well as very small amounts of water that can be dried immediately with towels. As for the most difficult part, the Orion capsule has a system similar to that used in the International Space Station. It is a container with a hose connected to a funnel through which urine descends thanks to an air suction system. Each astronaut will have their own hose and, since the crew has three men and one woman, it will adapt to both male and female anatomy, as necessary. Where does all that go?. Once the urine is collected, it is released into space. Regarding feces, they are also collected by suction and stored in sealed bags that will travel to Earth on the return trip. Best of all, this system is isolated, so astronauts can relieve themselves alone. There is a curtain that can be removed if they need more space and a door in the floor of the capsule that allows them the privacy they craved on the Apollo missions.

We believed that astronauts from the Apollo missions left the earth. Actually, they did not completely abandon the atmosphere

August 25, 2025 by usatoday24

The idea that space begins where heaven ceases to be blue is a story for children. Decades of scientific research show that the Earth’s atmosphere It is much bigger than it was believed. Not even the 12 people who stepped on the moon abandoned at all their influence. Where the earth ends. As Explain the expert in heliophysics From NASA, Doug Rowland, there is no clear border. “The atmosphere does not stop at Everest, or where the planes fly. It continues and continues, becoming less and less dense as you go up.” The International Space Station, which orbits our planet about 400 kilometers high, experiences sufficient air resistance to need a periodic impulse. Otherwise, it would fall back to earth. But the real surprise came after Decades of Observations of Soho (Solar and Heliospheric Observatory), a joint mission of ESA and NASA. To the moon and beyond. A study Based on data from the Soho Observatory, he revealed that the outermost layer of our atmosphere, a faint cloud of hydrogen atoms called Geocorona, extends up to 630,000 kilometers, almost twice the distance from the earth to the moon. When astronauts from the Apollo 16 mission installed the first telescope on the moon in 1972, they captured an image of the geocorone shining in ultraviolet light. What they didn’t know was that they were still inside her. In words of Igor Baliukinmain author of the study: “The moon flies through the atmosphere of the earth.” Oxygen on the moon. The presence of the earth on the moon is not limited to hydrogen. Earth oxygen also arrives at our satellite. It occurs for about five days a month, when the moon passes through the Magnetocola of the Earth, the magnetic tail of our planet. Every time it happens, Oxygen ions are accelerated to the satellite and are embedded in the lunar soil. Researchers believe that this process has occurring 2.4 billion years, which means that lunar regolite could keep a record of the evolution of our own atmosphere. The “official” border of space. The Atmosphere is divided into layers: Trophosphere, stratosphere, mesosphere, termosfera and exosphere. The latter, the exosphere, starts about 700 kilometers high and merges with the solar wind about 10,000 kilometers. But their particles are so scarce and so scattered that they can escape towards space. The “official” border of the space is, by convention, the line of karm, located 100 kilometers from altitude. It is considered the point at which traditional aeronautics is no longer possible due to lack of air. However, the geocorone, the luminous part of the exosphere, is the proof that the atmospheric influence of our planet comes much, much further.
