50 Amazing Facts that will surprise you About Space Travel | Amazing Facts 4U

  1. The first rocket was called the V-2 Rocket and was made by a German scientist and Engineer Wernher Von Braun during World War II and was used as a weapon against the allies.
  2. Fact is a spacecraft needs to accelerate to just over 17,000 miles per hour to escape the Earth’s gravity (approximately 5 miles per second). This is called escape velocity.
  3. Amazing fact is at blast-off around 300,000 gallons of water is released beneath the shuttles engines as a noise suppressant.
  4. Fact is space shuttle main engine weighs 1/7 the as much as a train engine but delivers as much power as 39 locomotives.
  5. The external tank on space shuttles is not painted. It is the only part of the shuttle that is lost after launch, so it is not necessary to worry about metal corrosion.
  6. The average journey into orbit takes about 8.5 minutes.
  7. Yuri Gagarin was first man to travel in space, on 12 April, 1961, orbiting the Earth once.
  8. The first American to orbit the Earth, John Glenn, flew into space on 20 February, 1962.
  9. On 20 July, 1969, Apollo 11 made the first Moon landing. Neil Armstrong and Buzz Aldrin walked on the Moon. Michael Collins manned the command module.
  10. Amazing fact is just twenty seconds worth of fuel remained when Apollo 11s lunar module landed on the moon.
  11. The last Apollo space mission, Apollo 17, took place in December 1972. Eugene Cernan and Harrison H. Schmitt landed on the Moon’s surface in a lunar module. In all, six Apollo spacecraft made successful landings on the Moon. Amazingly no one has left Earth’s orbit since then.
  12. An astronaut can be up to 2 to 3 Inches taller returning from space due to expansion of cartilage disks in the spine in absence of gravity.
  13. Fact is if you went out into space, you would explode before you suffocated because there’s no air pressure.
  14. Galileo spacecraft traveled 2.4 billion miles on it’s way to Jupiter using 67 gallons of fuel on the way to control the flight. Amazingly this is equivalent to 36 million miles travel per gallon.
  15. A full moon is nine times brighter than a half moon.
  16. It would take more than 150 years to drive a car to the sun.
  17. When Galileo probe entered the Jupiter atmosphere , it was traveling at amazing 106000 miles per hour which is the fastest speed by man made object.
  18. In space, astronauts cannot cry properly, because there is no gravity, so the tears can’t flow down their faces!
  19. Astronauts cannot belch since there is no gravity to separate liquid from gas in their stomachs.
  20. In zero-G, astronauts can lose muscle mass at a rate of 5% a week. Most people know at least the basis of that fact, but bones can also atrophy at a rate of 1% a week. Blood pressure evens out throughout the body as well. The body of an astronaut gets so used to this that when they return to earth they often need to be taken on stretchers.
  21. For a satellite or spaceship to stay in orbit 200 Km above earth , It must amazingly fly at over 8 Km per Second.
  22. Water acts as jelly out there in space.
  23. Amazing fact is that the metric system was the culprit for the loss of the Mars Climate orbiter.
  24. Amazingly NASA’s Voyager 1 spacecraft has reached the edge of our solar system after 33 years and after traveling for 10.8 billion miles . The craft was first launched on September 5th, 1977 .
  25. The second satellite ever launched by the United States is still orbiting the earth. Vanguard 1 was launched on March 17th, 1958, achieving the highest altitude of any man-made vehicle up to that point, and was also the first satellite to be powered by solar energy.It is predicted to remain in orbit well into the 22nd century.
  26. The Mars Opportunity rover was expected to last for 91 days. Amazingly it’s still going after 9 years!  It was launched from Earth on July 7, 2003. It landed on Mars on January 25, 2004.
  27. Astranauts abroad the international space station amazingly see 15 Sunsets and 15 sunrises per day averaging one every 45 minutes.
  28. The International Space Station is the most expensive object ever built, at US$150 billion. Roughly half of the total price was contributed by the USA, the rest by other nations including Europe, Japan and Russia.
  29. The International Space Station or ISS was completed in 2011, but people have been living on it since November 2nd, 2000.
  30. The ISS is primarily composed of 15 pressurised modules (seven US, five Russian, two Japanese and one European) and four large solar panels. It weighs amazing 420,000 kilograms (925,000 pounds), which is more than 320 automobiles.
  31. The total length of the ISS from end to end is amazing 109 metres (357 feet), longer than both a “proper” football field and an American Football field.
  32. The International Space Station has a liveable space equivalent to a five-bedroom house and travels at 17,500 mph.
  33. The Vehicle Assembly Building at NASA’s Kennedy Space Center is so large that rain clouds form inside it.
  34. The Apollo 12 mission crashed a 2.5 ton piece of metal into the moon causing the moon to amazingly “ring like a bell” for nearly an hour!
  35. Sunita Williams, the astronaut holds the record for the most days in space for a female (195).  On April 16, 2007 she completed the first marathon ran by someone in orbit. Her sister ran the marathon on earth while Sunita ran the marathon in space.  They were updated on each other’s progress throughout the race.  Sunita finished the Boston Marathon in 4 hours and 24 minutes. In 2008 Sunita Williams once again ran the Boston Marathon but this time on earth.
  36. Amazingly unprotected human being can survive in space for just 2 minutes.
  37. If two pieces of metal touch in space, they amazingly become permanently stuck together. This doesn’t happen on earth because the atmosphere puts a layer of oxidized material between the surfaces.
  38. The Saturn V rocket which carried man to the Moon develops power equivalent to fifty 747 jumbo jets.
  39. Astronauts in orbit feel weightless because they are constantly falling, not because there is no gravity in space.
  40. The full cost of a spacesuit is about $11 million although 70% of this is for the backpack and the control module.
  41. A space suit can weigh between 50 and 350 pounds on Earth.
  42. Launch and entry space suits are orange as an aid to search and rescue operations in case of emergency. Suits for spacewalks are white to reflect the sun’s heat.
  43. Fact is oxygen is circulated around the helmet in space suits in order to prevent the visor from misting.
  44. The middle layers of space suits are blown up like a balloon to press against the astronaut’s body. Amazingly without this pressure, the astronaut’s body would boil!
  45. The gloves included in the space suit have silicon rubber fingertips which allow the astronaut some sense of touch.
  46. In 1962, the U.S. blew up a hydrogen bomb in space that was amazing 100 times more powerful than Hiroshima.
  47. In movies, a human body explodes if it is pushed into space without a suit. But it’s mostly fiction. Although liquids do boil in a vacuum, your blood is kept under pressure by your circulatory system and would be just fine. It is lack of air that will kill you.
  48. Amazing fact is about half of any space walk on International space station is spent in total darkness.
  49. We are all traveling through space. Latest estimates put the speed of the Earth in relation to the cosmic background radiation at 390 km/sec, or 872,405 miles per hour.
  50. Robotic spacecraft have so far landed on the moon, Venus, Mars, and several asteroids.
