Can a phone work in outer space?

No. Take an ordinary smartphone and put it in outer space and you’ve got a big problem: Inadequate cooling. The phone is going to destroy itself with its own heat. Normal conduction and convection cooling will not work, all you have is radiation and at those temperatures it’s a small part of the cooling.

Do astronauts have privacy in space?

As of April 2021, the International Space Station has seven permanent crew quarters, or personal spaces for astronauts to sleep and work during their stay on station. Each location provides a small pocket of privacy for astronauts and cosmonauts during their stay on orbit.

How big is a cell phone antenna?

about 5-7″ long
It is typically about 5-7″ long. Absorb the last few sentences. What do they mean? For efficient radiation at mobile/cellular phone frequencies, the antenna must essentially be the size of the whole device.

What are the requirements for an antenna used in mobile phone?

Mobile phone antenna should have a low directivity, because is not useful to use an antenna with high directivity, that is the received signal it can be from different directions. On the other hand the base station needs a high directivity.

Will Starlink take over the internet?

SpaceX said that it expected Starlink to reach global serviceability sometime in fall 2021 — though regional availability will depend on regulatory approval.

Why don’t spacecraft antennas on Mars pick up radio signals?

For example, they did this during launch and Mars Orbit Insertion. The data rate of these antennas is lower because they focus the radio beam much more broadly than the high-gain antenna, meaning less of the signal reaches Earth. The Deep Space Network on Earth, however, can “see” the signal even when the spacecraft is not pointed at Earth.

How does Mars reconnaisance orbiter communicate with Earth?

Mars Reconnaisance Orbiter even captured images of the spacecraft on its parachute during entry, descent and landing. The cruise stage had two antennas that were used to communicate with the Earth. The low-gain antenna was omni-directional and was used when the spacecraft was near the Earth.

Why does Mars Science Laboratory share time on the DSN antennas?

The Mars Science Laboratory spacecraft must therefore share time on the DSN antennas. A sophisticated scheduling system with a team of hundreds of negotiators around the world ensures that each mission’s priorities are met.

How does the size of the antenna affect the signal?

The larger the antenna, the stronger the signal and greater the amount of information the antenna can send and receive. The Mars Science Laboratory, while in its cruise stage configuration, communicated through low and medium-gain antennas.
