This article traces the history of space travel and what more can be achieved.
|The distance till Jupiter is 365 million miles. The distance till Pluto is 4.67 billion miles. Present spacecraft is ill equipped to carry humans to such far off places. Space shuttles can travel at a speed of 17,500 miles per hour in orbit around the earth. The nearest star is 4.22 light years from the earth. Our latest spaceships would take about 81,000 years to reach the nearest star. Manned spaceships would also require rations of food, water and air to sustain themselves during the journey and after reaching a target. To maintain themselves they also would require medical aid for common illnesses and emergencies. All this will have to be taken care of if serious journeys to other planets orbits or to nearest stars have to be carried out.
Space travel is also possible to carry out tourist spacecraft to travel into orbit around earth or to other planets. This can add to the excitement and amusement of people wanting to be space travelers. The cost of such journey's can be minimized for better affordability. The first human spaceflight was Vostok-1 and carried Russian cosmonaut Yuri Gagarin. The first artificial object to land on the moon was Luna 2 in 1959. Luna 10 was the first artificial satellite to orbit the moon. The Apollo 11 was the first human landing on the moon. The first flyby to Venus was the Mariner 2. It reached an orbit of 34,773 kilometers around Venus. Pioneer 10 reached Jupiter in 1973. Further, travel and exploration of space is possible if we develop better facilities and infrastructure of spacecraft's and space shuttle's.
