SpaceX Crew Dragon: A new era in space exploration

SpaceX Crew Dragon: A new era in space exploration

  • On Sunday night, two American astronauts flew to the International Space Station, the world’s only space-based laboratory, located about 400 km from the earth, in a journey that has been undertaken hundreds of times earlier.
  • It was the first time that astronauts used a spaceship built and launched by a private company, and the event is being widely seen as the beginning of a new era in space exploration.
  • Two NASA astronauts flew onboard a spaceship named Crew Dragon built by SpaceX.
  • The rocket, named Falcon 9, which carried the spaceship into the orbit, was also built by SpaceX.
  • The Florida launch facility used for the flight still belonged to NASA, however, and had previously been used to launch American spaceships including the Apollo missions that took human beings to moon.
  • The mission was called Demo-2, in keeping with the fact that it was still only a ‘test flight’, which if successful, would lead to more missions in the coming months.

What’s the big deal

  • For NASA, it was the first flight of its astronauts on an American spaceship, launched on American soil, after nine years.
  • NASA used to have a fleet of five spaceships under its Space Shuttle programme, that were used to make a total of 135 of journeys into space, and the International Space Station (ISS), in the 30 years between 1981 and 2011.
  • Two of these were destroyed in accidents, the Challenger in 1986 and Columbia in 2003, each resulting in the death of seven astronauts.
  • After the 2003 accident, in which India-born astronaut Kalpana Chawla was among those killed, the US government had decided to close the Space Shuttle programme.
  • The three remaining spaceships, Discovery, Atlantis, and Endeavour, were formally retired in July 2011, even though they were fit for many more flights.
  • It was decided that it probably no longer made sense for NASA to build and operate these spaceships. It was not just costly, but was also consuming a lot of scientific resources.
  • The transportation needs could easily be fulfilled by space vehicles that some private companies were promising to make. Accordingly, it was decided to help and support these companies in building these spaceships that can be hired by other agencies as well, and even private individuals.
  • The NASA collaboration with SpaceX and Boeing was a result of this.
  • In the meanwhile, NASA hitched rides on Russian spaceships to travel to the ISS, for which it paid tens of millions of dollars for every trip.
  • The new option is expected to be cheaper than that, besides offering the comfort of operating from home soil and eliminating dependence on a foreign country.

Private participation, so far

  • The involvement of private industry in the space sector is nothing new.
  • There are literally hundreds of private entities building commercial satellites for their clients.
  • Launch services are still a somewhat restricted zone, considering that it requires elaborate facilities and deep pockets, but here too, there are several players apart from SpaceX and Boeing.
  • Many, like Virgin Galatic of businessman Richard Branson, have been already made space flights and hope very soon to start offering passenger rides to space whoever can afford to pay.
  • In fact, last year, a spacecraft built by Scaled Composites, a US company, even took a human being for a very short ride into space, becoming the first private spacecraft to do so.
  • In India the private space companies collaborate with the Indian Space Research Organisation (ISRO), in building and fabricating the components that go into making rockets and satellites.
  • There are several that have started making satellites for their own use, or for their clients.
  • However, launch services, including the building of rockets or launch vehicles to take the satellites into space, is something that is still some distance away in India right now.

Window to the future

  • Sunday’s flight also underlines the fact that space research and exploration is now a much more collaborative enterprise than earlier.
  • The International Space Station itself is a good example of international cooperation in the space sector.
  • The space facility is set to retire somewhere around 2028, and its replacement being planned is likely to have participation from at least ten countries, and possibly private players as well.

Way ahead

  • There is also a growing realisation that space agencies need to direct their energies and resources more towards scientific research and deep space exploration.
  • Private players are expected to infuse fresh investments, and also technological innovation that will benefit everyone.
