Fossil Fuels have made manned space exploration possible.
moon baby :D
1. The cost of manned space missions are higher per mission, meaning less missions. 2. Humans are subject to high risks. 3.Complex systems must be installed (i.e. life support) 4. Humans are restricted to where they can go due to 'physical' boundaries.
Hurricanes are measured through a combination of satellite imagery, manned flights into the storms, Doppler radar, and ground ad seas surface based observations. Tornadoes are more difficult because they are smaller, shorter lived, and overall less predictable. Measurements have been made using Doppler radar and ground and ground based probes. Even then, most tornadoes do not have any measurements taken, so strength is estimated based on the damage caused.
It depends how fast the spaceship goes. If it went like as fast as a car it would take 4 months.EDIT: The distance from Earth to Venus can varies frequently due to Earth's increased length of orbit around the sun. The closest it can be to Earth is ~38 Million Kilometres, and the furthest it could be is ~261 Million Kilometres. This means that if it were possible to say, drive to Venus in your space-car at 80 km per hour, it would take you anywhere between 19,791 days (54.22 non-leap Years), and 135,937.5 days (372.43 non-leap Years).Of course, a space ship travels much faster than a car. The fasted manned spacecraft was the Apollo 10, which reached speeds of about 40,000 kilometres per hour. So if you were travelling at that speed constantly from start to stop, it'd take between 40 and 272 days.Once again this isn't actually correct. A spaceship would not maintain such a speed throughout the whole flight; the record speed Apollo 10 set was on the return flight from the moon, presumably during re-entry. It was set by the Command/Service Module (not the part that would have landed on the actual moon, the bit that stayed in space). Apollo 10 didn't even land on the moon; the module specifically built for that was intentionally underfueled.In conclusion; were a spaceship able to maintain a flight speed equal to that of the fastest manned vehicle travel, and not factoring in any problems, emergencies, time spent in orbit or on the actual face of Venus, and not including the fact that Venus' atmospheric pressure is 92 times greater than that of Earth's, making attempts to land safely much more difficult (although safety was never mentioned), it would take between 40 and 272 days.
Quote from the Related Link: "The human body, for the most part, is made up of water (60%+/-) and other substances that are approximately as dense as water - with very little gas. What gas the human body does have would get compressed as the body goes further and further down. Specifically, any gas in your lungs, ear (and related canals), blood, and stomach will become compressed. Let's take SCUBA diving as a basic intro to how the body and how gasses behave under water. When you dive under water, you'll feel pressure in your ears - this is the air in your ears (and related canals) getting smaller as a result of the water pressure. If you can allow water to enter this space, the pressure equalizes and the discomfort disappears. As the air in your chest compresses, you have less air to breathe - but fortunately, you have an air tank and can add compressed air to your lungs (via breathing), thereby filling your lungs and allowing you to breathe. The reason(s) why human beings don't go to thousands of feet without specialized suits doesn't have to do with getting crushed - it has to do with a few things: 1) The Bends (decompression sickness). When the body is under pressure, it behaves a bit like a bottle of soda. If the pressure is released too quickly, bubbles form in your body (brain, blood, joints). This can result in anything from discomfort to instant death - with anything in between (brain damage, stroke, lung problems, nerve damage, etc). If you go down to say 3000 feet and try to surface, it would likely take a LONG time to decompress appropriately and safely to come back up. 2) Breathing. Oxygen becomes TOXIC under pressure. 21% of air is oxygen - this becomes toxic at depth, so there are different artificial gasses and different levels of oxygen in some tanks, allowing divers to go deeper. The maximum depth that I could find on the internet was @1800 feet. Beyond that, there is no way for divers to breathe. So - in short, you can't/won't get crushed by the ocean - you die because you can't breathe."
NASA has long term plans that include the exploration of Jupiter and its moons, and possibly a manned landing on one of the moons. A manned landing on Jupiter is not possible with our current level of technology.
the moon
yes,possible for a manned mission to Mars by 2023
moon baby :D
what are the three characteristics of the manned landing i dont the answer
This question was posted on April 6, 2011. Here it is October of 2012, and I'm still waiting for the so-called "following" list of multiple choices to appear. If this keeps up, the near future of manned space exploration will be here before I can start selecting the right answer from it.
What are the names of mars two natural satellite
The second American space program aimed at making further progress toward manned exploration of the Moon was the Gemini program.
manned-not until travel time is reduced. There have been unmanned probes.

Manned space travel to Titan is not yet feasible, but probes have been there already.
Man has not physically been to Mercury but un-manned robots have been there. These robots have helped us to better understand our distant neighboring planet.
