Surgeon Robot Arm Launched into Space

Scientists have made another innovation. The robotic surgical arm they developed, called MIRA (Miniaturized In-vivo Robotic Assistant), will allow doctors to perform surgeries remotely and will be used in surgeries on the International Space Station. MIRA was developed by medical startup Virtual Incision. This robotic arm, which can use a scalpel, can cut human flesh in a microgravity environment. To test this, the robotic arm was launched to the International Space Station aboard SpaceX’s Falcon 9 rocket. The launched capsule named Cygnus carries a total of more than 3 tons of material, including a two-kilogram robot arm and other materials. In August 2021, he performed his first simulated procedure in space by cutting rubber bands that resembled human tissue to prepare for medical procedures in a microgravity environment. Michael Jobst, one of the surgeons who tested MIRA, said in an interview with CNN, “If there is bleeding in a live patient, it is my job to stop that bleeding immediately. But having a delay of 800 to 850 milliseconds between seeing the blood loss and doing something about it is actually like saying, ‘Okay, one Mississippi, two, and then going ahead and solving the problem,’ he said. ‘Five seconds during a surgery is an eternity. It can be a period of time, and even half a second or a fraction of a second will be important. So this is a big challenge.” He said. Thanks to a grant from NASA, MIRA will operate in a microwave oven-sized experimental cabinet on the space station, performing activities that simulate cutting stretched rubber bands (the equivalent of human tissue) and anything used in surgery.

The most interesting feature of MIRA is that it cannot use its robotic arms on its own, it can only do its job with the half of a real-life human surgeon who can communicate with it. Currently, the creators of MIRA are working on making the robot fully autonomous so that this robot surgeon can perform all procedures on his own.

Gezeravcı: “There are many spacecraft that cause garbage.”

Turkey’s first astronaut, Alper Gezeravcı, met with young people in Edirne and made striking words in his speech. “Currently, there is a spacecraft orbiting the Earth in an uncontrolled manner, which is instrumental in space resolution. A study on this is being carried out within the United Nations. “Countries will no longer be able to send spacecraft and satellites into orbit in an uncontrolled manner as they wish,” he said.

During his meeting, Gezeravcı gave advice to the students about space and talked about the 14-day period he spent in space and his experiences. Answering the students’ questions, Gezeravcı explained how they eat in space, how they sleep and how they carry out scientific studies, and the whole process they went through.

Gezeravcı, who gave a very enjoyable interview, attracted the attention of all the audience. “I saw chain lightning appearing simultaneously at many points that you cannot see from Earth, and this impressed me very much. vision in space

I didn’t have any problems with it. I had the opportunity to observe the colors of the world in a very beautiful way. There was something even more beautiful, the colors of the Moon. While we are on Earth, we have a beautiful atmosphere that filters out the beneficial sun rays and foreign matter that may be directed towards us. This atmosphere changes the lights as it filters these rays. We can see a much clearer and crystal-like image of the Moon we see on Earth than the image we see on the space station. I had the chance to photograph this too. Astronauts may experience some muscle loss. “I didn’t experience any muscle loss because I did sports there,” he said. “There are many spacecraft that end up in space junk”

Gezeravcı said, “No one could have predicted that space could become a garbage dump like this. No one could have predicted that the studies and developments would come this far in such a short time. He continued, “There is no obligation to bring the satellites sent into space back to earth, and since spacecraft and satellites are launched into space every day with the developing technology, there are many spacecraft that turn into space garbage.”

“A study is being carried out within the United Nations”

Gezeravcı said, “Currently, there are spacecraft orbiting the Earth in an uncontrolled manner, causing space debris. A study on this is being carried out within the United Nations. From now on, countries will no longer be able to send spacecraft and satellites into orbit uncontrollably or as they wish. “This was one of the important issues,” he said.

The Moon’s South Pole May Not Be the Best Place to Land

Cracks and rocks on the surface of the Moon are caused by seismic events throughout history. These seismic events occurred as the Moon contracted and parts of its crust were pushed on top of each other. According to the article published in The Planetary Science Journal on January 25, 2024, evidence was presented that some areas in the south polar region of the Moon, proposed for future landings, are near fault zones and are vulnerable to earthquakes.

The sunflower seed shrank over time due to cooling. A previous analysis of NASA’s Lunar Reconnaissance Orbiter (LRO) images discovered that the Moon’s contraction resembles a drying grape. According to this analysis, the Moon is still shrinking, causing earthquakes along faults. The study found that some cracks and fissures in the southern part of the Moon were linked to a powerful moonquake captured by Apollo seismometers in the 1970s. The study team used computer models to determine surface stability in that area and found that some slopes were susceptible to landslides caused by moonquakes.

“Our modeling suggests that shallow moonquakes that can produce strong ground shaking in the south polar region could result from slip events on existing faults or the formation of new thrust faults,” said study lead author Thomas R. Watters, an expert in planetary tectonics, “while planning the location and stability of permanent lunar outposts.” “The global distribution of young thrust faults, their potential to become active, and the potential to form new thrust faults from ongoing global contraction should be taken into account.” said.

These earthquakes on the lunar surface may threaten the work of the Artemis III manned exploration vehicle, which is the third phase of the Artemis mission. Shallow moonquakes, which occur at a depth of approximately 161 kilometers, can last for hours, posing a serious danger to Artemis.

NASA wants to explore the south pole of the Moon because some parts of the south pole have permanent ice because they do not see the sun.

Artemis Missions

In this article, we will discuss the Artemis mission in our news above. NASA will explore more of the Moon than ever before with Artemis missions. With these missions, NASA plans not only to go to the Moon but also to settle there. Artemis missions consist of three stages. As part of the Artemis 1 mission, the Orion capsule will be sent approximately 65 thousand kilometers beyond the Moon. After this mission, Artemis 2 and Artemis 3 missions will be carried out in 2025 and 2026, respectively. Artemis 2 will follow the route of Artemis 1 with a crew of 4 people. The Artemis 3 mission will send the first woman to set foot on the Moon. Each Artemis mission is projected to cost approximately $4 billion. One of the goals of Artemis 1, the first phase of the mission, is to conduct some critical tests for the first manned mission to the Moon years later. Some of these tests include the first integrated flight of the Orion spacecraft and the Space Launch System launch rocket. Artemis 1 was launched from Kennedy Space Center on November 16, 2022. It landed in the Pacific Ocean on December 11, 2022, approximately 25 days after launch. In the image below, you can observe the movement of Artemis 1 around the Earth and the Moon. Why Do We Return to the Moon?

In addition to humanity’s search for habitable planets other than Earth, it is necessary to establish a habitable environment on these planets. NASA aims to return to the Moon to find water and other resources that will support long-term space research. In line with this goal, we will strengthen our hand for Mars with the knowledge and experience we will gain thanks to this mission to the Moon.

This Week In Our Art Corner

Brightest Stars

This week, in our art corner, we are examining the brightest stars we have observed so far. Some of the stars we will examine can be easily seen with the naked eye, despite the light pollution in cities. On a clear day, you can see an average of 9000 stars. You can find the positions of these stars using the SkyView app. As we enter the spring months, we hope that this information will be useful to you.

Brightest star: Sirius The brightest star in the sky as viewed from Earth is Sirius. It is 23 times brighter than the Sun. The best time to see Sirius from points in the northern hemisphere, such as Turkey, is in winter.

Canopus
Canopus is located in the constellation Carina. Carina together with two other constellations once formed the constellation Argo Navis. The name Argo Navis was given to the Argonauts who sailed on the ship Jason in search of the Golden Fleece in Greek mythology. The other two constellations form the sail (Vela) and stern (Puppis) part of the ship. Spacecraft such as Voyager 2 navigate in space using light from Canopus.

Arcturus
Arcturus is the brightest star seen from the northern hemisphere. Known as the Bear Watch, Arcturus watches the constellation Ursa Major from around the north celestial pole. Its name is derived from the Greek word arktos, meaning bear.

You can also check out other stars in the image above. Even though you are not on the list, you are the brightest star for us. May your star always shine.
