What is the fastest rocket we have to travel in space, 7,000 mpr?

Realistically speaking, those sci - fi stories like Star Trek and Star Wars and even the Martian movie seem so radical that they don't really make sense in the world we live in now.  Nasa wants to explore Saturn's moon Titan, but what would happen if something happens to the spacecraft, like if it breaks apart.  All those years gone by to get there would've been wasted.  Surprised, no one has found any life or micro organisms other then some remnants of some water on mars when we've been sending those probes in space for years.  I wonder if there is more out there than the public knows, it's just the evidence isn't enough I'm assuming.


mph not mpr.

    Actually, the rockets travel around 18,000 MPH.  The Shuttle traveled at 18,000 MPH which is the speed needed to break free of the Earth's gravitational pull and to sustain orbit.

    The Voyager II space craft, which is the first spacecraft to leave the solar system, travels at 38,000 MPH.

    The failure of a mission due to the craft being destroyed is just part of the game; it is rocket science after all.  If you're going to explore the universe, then you have to understand the risks involved and engineer your craft accordingly.  The risks are there as NASA's failure to land on Mars has proven.  However, not exploring because of the risks will ensure that you never make discoveries.  What would have happened if Columbus or Marco Polo had the same negative attitude?  If you don't take risks, you never achieve anything.  But this is not to say that one should ignore the risks, but instead understand them (often by past failures) and to design spacecraft so that the risks are minimized.  There will always be risk in space travel just as there will always be some degree of risk when you get in your car and drive to school or work.  The risks can be greatly minimized by design and behavior.  Just like how you should not drive drunk, or use a 4x4 instead of a Ferrari to drive off road.

    The fastest outward-bound spacecraft yet sent, Voyager 1, has covered 1/600 of a light-year in 30 years and is currently moving at 1/18,000 the speed of light. At this rate, a journey to Proxima Centauri would take 80,000 years.

    Update for Aug. 11: NASA and the United Launch Alliance have postponed the Parker Solar Probe launch by at least 24 hours, to Aug. 12, due to an issue with the probe's Delta IV Heavy rocket. Read our full story here.

    Early tomorrow morning (Aug. 11), weather permitting, NASA will launch its newest spacecraft, called the Parker Solar Probe, aboard a huge United Launch Alliance Delta IV Heavy rocket — and by December 2024, it will become the fastest spacecraft ever.

    That's when the probe will reach its closest point to the sun, coming within 3.83 million miles (6 million kilometers) of our star. At that point, the spacecraft will be speeding along at a whopping 430,000 mph (692,000 km/h). On Earth, that would be the equivalent of traveling from Washington, D.C., to Tokyo in less than a minute — or from D.C. to Philadelphia in less than a second.

    7000 won't even get you to the moon. If you don't know that it ain't "we" anyway.

    And that's because your exactly right. What if there's problems.

      5 Mph will get you to the moon. If  a constant forward velocity or r p outside Earth's gravitation. Its only shooting a conventional rocket OFF Earth's surface that requires escape velocity.

    Actually the speed of the space station is approx 5 miles per second.. you want that in MPH how about doing some math

    We are getting to 200,000 MPH with the slingshot method, the Japanese comet chaser 240,000 MPH.

    A new Hall-Plasma drive soon to be flight tested promises 500,000 MPH

    Forget deep space, humans won't be leaving the solar system.

    I don't think it's to do with anything being kept from the public. It's more that the scientific process is influenced by what it's prudent to say in order to advance one's career, and there's a mindset that much of the data which supports the existence of life elsewhere tends to be explained in ways which allow us to continue thinking we could be alone in the Universe. But looking at the evidence from outside science, which of course means isolation from an academic community and possible operation of the Dunning-Kruger Effect, I would say there was evidence for microorganisms on Mars and in the upper atmosphere of Venus, and also that panspermia from Earth does take place, although how long the organisms involved survive is another question.

    The speed a Spacecraft can go depends on how much fuel it can carry for acceleration. Sometimes it can use a gravity assist from a planet to speed it up.

    There are accidents and breakdowns of space probes. Space missions are dangerous and expensive, and take a lot of time.

    There is a real need to look closer at things

    For Velocity, the fastest probe is New Horizons

    35, 000 mph driven by Ions towards its last Gravity Assist in the Kuiper Belt

    It will eventually overtake Voyager One

      Look what New Horizon speed was approaching Uranus, then the slingshot to the Ort cloud.
      Going the wrong way to catch Voyagers.

    Clearly, you nothing of space propulsion.

    For starters, just getting to Earth orbit involves accelerating to 17,500 MPH. To head for the Moon, you need 24,500 MPH.

    The Parker Solar Probe peaked at 153,454 MPH.

    And yes, sometimes a probe suffers a failure after a long voyage. Them's the breaks.

    speed is relative.  

    Parker Solar Probe Becomes Fastest-Ever Spacecraft. At about 10:54 p.m. EDT, Parker Solar Probe surpassed 153,454 miles per hour — as calculated by the mission team — making it the fastest-ever human-made object relative to the Sun. 

    The Apollo 10 crew; Thomas Stafford, John W. Young and Eugene Cernan achieved the highest speed relative to Earth ever attained by humans; 39,897 km/h, 24,791 mph.
