How did we communicate with the astronauts on the moon?

When Neil Armstrong and Buzz Aldrin stepped onto the moon in 1969, a S-Band Transponder designed and built by General Dynamics was the only communications link the Apollo 11 Astronauts had to NASA’s mission control and millions of people watching on Earth.

Would you run faster or slower on the moon?

And, according to the study they published today in the Journal of Experimental Biology, humans can run a lot faster in lunar gravity than anyone ever expected. There, the astronauts were asked to run on a treadmill during 20 second-long dips at lunar gravity.

How long is the communication delay between Earth and moon?

Echo delay and time spread Propagation time to the Moon and back ranges from 2.4 to 2.7 seconds, with an average of 2.56 seconds (the average distance from Earth to the Moon is 384,400 km).

Do cell phones work on the Moon?

You wouldn’t be able to use your normal phone made to operate at 1 atmosphere plus or minus a little pressure, in the near vaccum of moon for much longer. The LCD, the plastics, the mainboard, and the battery would all outgas and either be damaged or destroyed. All volatile condensable materials may vaporize.

How did the president talk to the astronauts?

On July 20, 1969, President Nixon spoke with crew members Neil Armstrong and Edwin “Buzz” Aldrin via telephone-radio transmission. While in the Oval Office on July 20, 1969, President Nixon used this green telephone to talk to the Apollo XI astronauts as they walked on the Moon.

How long does it take to get a signal from the Moon?

Radio waves propagate in vacuum at the speed of light c, exactly 299,792,458 m/s. Propagation time to the Moon and back ranges from 2.4 to 2.7 seconds, with an average of 2.56 seconds (the average distance from Earth to the Moon is 384,400 km).

Does time go faster in the moon?

Time passes about 0.66 parts per billion faster on the Moon than on Earth, due to not being in as strong a gravity field.

What moves faster the moon or Earth?

Because the Earth rotates faster (once every 24 hours) than the Moon orbits (once every 27.3 days) the bulge tries to “speed up” the Moon, and pull it ahead in its orbit. The Moon is also pulling back on the tidal bulge of the Earth, slowing the Earth’s rotation. The Earth’s rotation is slowing down because of this.

What type of video was used to record the Moon landings?

If we go along with the idea that the Moon landings were taped in a TV studio, then we would expect them to be 30 frames per second video, which was the television standard at the time. However, we know that video from the first Moon landing was recorded at ten frames per second in SSTV (Slow Scan television) with a special camera.

How was live TV transmitted from the Moon?

Live television was transmitted from the moon to 3 grounds stations, two in Australia and one in California. The signal was converted to a standard broadcast signal and then sent to Houston, via, satellite, landline or microwave antenna. These graphics show the path of the television feed. Bottom line is,…

How many people watched the Moon landing on TV?

The Moon landing was one of the biggest television events in history, reaching an estimated 650 million viewers. This incredible milestone in broadcasting was the result of years of planning and technological development.

Why were the images broadcast from the Moon upside down?

At first, the images broadcast from the Moon were upside down, due to the position in which the television camera had been mounted on the Lunar Module for safe transport. Operators at Honeysuckle Creek flipped the picture for broadcast; when the astronauts moved the camera to a tripod, it was flipped back around.
