Do astronauts still use the radio to communicate or was it in the ancient days?

Firstly, neither astronauts or radio existed in ancient times. Secondly, radio has always been used by astronauts and continues to be so, because it is the only thing that works across the distances and through the vacuum.

How do astronauts communicate with NASA?
Astronauts communicate with their controllers on the earth the same way airline pilots do ... by radio. Since astronauts may be over any part of the earth at any given time, a network of ground stations is organized around the world, to communicate with the spacecraft and relay the communications to/from the Johnson Space Center near Houston TX. -------------------------------------------------------------------------------------------------------------- Bi-directional communications between astronauts and ground receiving stations is accomplished using communication radios that transmit and receive high-frequency radio waves; however, real time bi-directional communications becomes increasingly impractical and eventually impossible as the distance between the astronauts and the ground receiving stations increases. Let's look at a voyage to Mars as an example. High-frequency radio waves travel at the speed of light (approx. 299,792 km/sec or 186,000 miles/sec) and as such, a message can take anywhere from 3 to 22 minutes to travel between Mars and Earth (and the same length of time for a response to get back), making normal (real time) conversations with ground crew or family members impossible. That having been said, astronauts will still be able to communicate back home and eventually receive a reply within 6 to 44 minutes depending on their distance from mother earth. It's analogous to communicating with someone via regular e-mail as opposed to a Live Messenger.
What are the release dates for We Can Still Be Astronauts - 2010?
We Can Still Be Astronauts - 2010 was released on: USA: July 2010
Can radio waves penetrate Earth's atmosphere?
yes, this is why we had two-way radio contact ( and still do) with NASA manned space craft. Also don't forget . . . -- radio contact with Apollo astronauts on the moon -- radio contact with the International Space Station -- receiving pictures and data from the Hubble Space Telescope -- receiving TV at home from stationary satellites -- radio contact with Curiosity on Mars -- radio-astronomy
How do aircrafts communicate with each other in airborne internet?
Most aircraft still use radio to communicate between themselves and the nearest Air Traffic Control Centre. Airborne Internet Access is still in its early days and various ways to enable it in a way that is safe for the aircraft
Do astronauts need to walk on the moon?
No, because most astronauts just make it into space but don't walk on the moon and their still considered astronauts.
Do astronauts still land this way?
yes
Which island use to communicate by whistling?
none Actually, the ancient whistling language "El Silbo" is still practiced on the Island of Gomera in the Canary Archipelago
Are radio waves electromagnetic energy?
Yes. That's how Earth-bound controllers communicate with the Hubble Space Telescope, the Mars rovers, and with the various space probes still in service. It's also how the Apollo astronauts were able to communicate with Houston while they were on the Moon, and how the forgotten crew currently on the International Space Station are able to tell their colleagues on the ground exactly what they are doing and generally what's going on up there. And it's also how you're able to receive 92 channels of TV from a satellite repeater with that little dish on the garage roof.
How did the Apollo 11 picture make it to earth?
if you are asking about the live television footage, the signal was sent via radio waves from an antenna on the LM and received by the Parkes radio telescope in Australia. If you are asking about the still pictures, they were brough home by the astronauts and developed on site at NASA.
Can you communicate at light speed?
Literally speaking, we do it every day, using the communications technique that we call 'radio'.Information carried by radio travels from place to place at the "speed of light".If you need an example of communication using nothing but visible light, thenyou'd have to consider something like waving at a friend across the street.But still, If we communicate through radio waves, to sound still takes time to reach our ears and get processed by the brain, taking up enough time.
Origin of the word ham in ham radio?
Amateur radio, often called ham radio, is both a hobby and a service in which participants, called "hams," use various types of radio communications equipment to communicate with other radio amateurs for public service, recreation and self-training. But we still don't know the origin of the word HAM.
