Future of Spaceflight
NASA aims to travel to the moon and beyondвЂ”again. This time they may have some company.
Welcome to the 21st-century space race вЂ“ one that could potentially lead to recycled rockets, 10-minute space vacations, and humans on Mars.
Private spaceflight is not exactly a new concept. Private companies have played a part in the industry since 1962, when NASA launched the first privately-built satellite.
In recent years, companies such as SpaceX and Boeing have started vying for more large-scale government contracts. The launch of SpaceXвЂ™s Falcon Heavy this February aims to demonstrate the world’s most powerful rocket since the Saturn V by placing SpaceX CEO Elon Musk’s very own Tesla roadster in the Sun’s orbit.
Others, such as Blue Origin and Virgin Galactic, have shown interest in specializing in space tourism. Test launch video from inside the cabin of Blue OriginвЂ™s New Shepard shows off breathtaking views of our planet and a relatively calm journey for its first passenger, a test dummy cleverly dubbed вЂњMannequin Skywalker.вЂќ The New Shepard is expected to have its first manned launch later this year.
Countless dreams of zero-gravity somersaults could soon become a reality. With the possibility of low-cost, reusable rockets and ambitious NASA plans for exploration on Mars, the coming years are set to be a major turning point in the history of spaceflight.
Looking to the Moon
Moon missions are essential to the exploration of more distant worlds. Extended lunar stays build the experience and expertise needed for the long-term space missions required to visit other planets. The moon may also be used as a forward base of operations on which humans learn how to replenish essential supplies, such as rocket fuel and oxygen, by creating them from local material.
Such skills are essential to the future expansion of human presence into deeper space.
Although humans have visited the moon before, our closest neighbor still harbors its own scientific mysteries to be exploredвЂ”including the investigation of water ice near the moon’s poles.
Future human moon missions will be preceded by robotic reconnaissance launches, between 2008 and 2011, to scout landing sites that may have the most resources available to astronauts. The moon’s south pole is considered particularly promising because it is rich in hydrogen and may be home to water ice as well.
A New Spacecraft
These new NASA missions are being spearheaded by the development of a state-of-the-art new spacecraftвЂ”but one with a retro feel.
The Orion crew exploration vehicle echoes the design of the original Apollo missions but updates its systems with modern technology. The new capsules will also be larger, with three times the volume capacity and the ability to accommodate a four-person crew. The new size has led NASA officials to describe the mission as “Apollo on steroids.”
The Orion capsule, which launches attached to a solid rocket booster and Apollo-like upper stage, is seen as a safer and more reliable design for future space exploration than the now-familiar space shuttle.
Once in space the flexible Orion vehicles will take astronauts to and from the International Space Station. They will also enter lunar orbit, a position from which landers can repeatedly visit the moon’s surface.
The Orion capsules, which may be reused up to ten times, will parachute to Earth like those of yesterdayвЂ”though they will arrive on dry land rather than via ocean splashdowns.
The Orion exploration vehicle was first launched in an unmanned test flight in December 2014, with the aim of sending a manned mission in the early 2020’s.
In the years beyond 2020, these spacecrafts may aid in assembling Mars-bound vehicles in orbit to take the first humans to the red planet.
