Space

The world of space is full of mysteries. Astronauts Sunita Williams and Butch Wilmore are stuck in space, while the American space agency NASA said that the return of astronauts is not possible this year. But meanwhile, news has come that Indian-origin NASA astronaut Sunita Williams, who is stuck in space, has contacted her mother. Sunita has also told her mother about the technical glitches there. She said that there is a delay due to some technical reasons. Sunita has assured her mother of a safe return to Earth. Williams told her mother Bonnie Pandya not to worry and that she will return safely.

What did Sunita’s mother say?

According to media reports, Sunita’s mother Bonnie Pandya said that Sunita told me not to worry about her, everything will be fine. When asked about the duration of her daughter’s stay in space, Bonnie said that I have been the mother of an astronaut for 20 years and this is her third flight. Even if there are some issues, we do not think there is any major problem. NASA officials just want to ensure that they are safe while returning. So they have decided to keep them there for some more time.

How does communication happen in space

Now the question is that there is no tower in space, nor is there any cable there, then how do the astronauts talk. Let us tell you that communication between earth and space takes place through space communication and navigation. According to scientists, communication in space is not easy, but still the space agency NASA has done a lot of work in it and now it is possible. Let us tell you that whether it is the rover present on the moon, the International Space Station or the Artemis Mission, NASA’s Space Communication and Navigation works to contact them. Apart from direct-to-earth satellites, NASA also has many relay satellites. For example, contact with the space station is done with the help of Tracking and Data Relay Satellites (TDRS). These satellites send signals to ground satellites located in New Mexico and Guam. For this work, they also take the help of orbiters revolving around the moon which forward the messages. The three TDRS are set in orbits above the Earth that cover the entire Earth and allow communication 24 hours a day, seven days a week.
