it would take round about say at least 64 hours - 94 hours so a long time!!
There is no star near mars.If there was, and it did explode, then you would not be alive to see it, let alone hear it.Sound cannot travel in a vacuum, so although you may see it, you would not hear it.
Radio waves travel at the speed of light. When the Spirit rover landed on Mars, signals were able to be sent from the Earth to Mars in 9 minutes 30 seconds. Unfortunately, the rover became stuck and hasn't sent a signal to Earth since March 22, 2010.
We (the US) haven't worked out all the details on keeping astronauts alive long enough to get back to Earth from Mars, but it takes about two years to send an unmanned probe there with our current technology. It takes 7 months to get to the Red Planet. It depends on the type of spacecraft, but between 6 months to a year. 260 days
Proxima Centauri is 4.2 light years away, so it would take 4.2 years for light from that star to reach us.
It is estimated that it would take at least three months to send human beings to land on Mars. The travel time depends on where Earth and Mars are in their orbits around the Sun. Time is of essence. The plans made in 2005 were three to nine months depending on when the flight was launched. The plan in 2005 was for three crew members. One was a Captain in the US Air force as the pilot. He was a graduate of Georgia Tech. Crew member No. 2 was a Russian Cosmonaut, No. 3 A high tech president of a start up company that designed much of the software required for the flight. Funding issues have delayed these plans as well as political issues.
It depends on where in the US you are going to.
About 9-10 hours air travel.
9 hours +
how long does it take a caego ship to travel from Germany to Los Angeles, CA., United States
About 8 hours
It will take approximately 14 hours 55 minutes
how long will it take standard us mail get here from New York to Michigan
2 weeks depends..
it doesn't
Three days
With enough money and time. President Bush wants the US to travel to Mars -- a huge cost in the many billions of dollars, and with current rocket technology it will take months to get there if the timing is just right between Earth and Mars solar orbits.
Depends on where you start and on your average speed
