SpaceX launches Cargo Mission for NASA to ISS

SpaceX successfully launched a Dragon spacecraft on a cargo mission for NASA to International Space Station (ISS).

About Mission

  • This is SpaceX’s fifth launch of year. The launch was rescheduled earlier due to some electrical problem on ISS.
  • It was launched on a ‘Falcon 9’ rocket, from Cape Canaveral in Florida. It is being used for first time.
  • Rocket on boards an un-crewed Cargo Dragon spacecraft.

The Dragon spacecraft

  • It is scheduled to reach ISS on May 6.
  • It carries 2,500 kilograms of research, supplies and hardware for astronauts living and working on ISS as part of the CRS-17 mission (17th resupply mission).
  • It will remain at ISS for about four weeks before coming back to Earth with more than 1,900 kg of research and return cargo.
  • It has flown before on other Missions namely, CRS-12 mission in August 2017

About The International Space Station (ISS)

  • It is basically an orbiting laboratory where its crew members conduct experiments in fields of biology, human biology, physics, astronomy, meteorology,etc.
  • It is a space station, or a habitable artificial satellite, in low Earth orbit (LEO).
  • Launched into orbit for first time in 1998, it is now largest human-made body in LEO.
  • Primary partners on project are USA’s NASA, Russia’s Roscosmos State Corporation for Space Activities (Roscosmos), EU’s European Space Agency (ESA), Canadian Space Agency and the Japan Aerospace Exploration Agency (JAXA).

Spacex to Launch NASA’s Asteroid-Smashing Mission

NASA has announced that SpaceX will fly its Double Asteroid Redirection Test (DART) planetary-defence mission. The total launch cost for NASA is estimated to be about $69 million.

DART

Double Asteroid Redirection Test (DART) is a planned space probe that will demonstrate the kinetic effects of crashing an impactor spacecraft into an asteroid moon for planetary defense purposes. The mission is intended to test whether a spacecraft impact could successfully deflect an asteroid on a collision course with Earth.

DART Planetary-Defense Mission

  • DART planetary-defence mission will be will launched by the Falcon 9 rocket from Vandenberg Air Force Base in California in June 2021.
  • The spacecraft will slam into “Didymoon,” the 540-foot-wide (165 meters) satellite of the near-Earth asteroid Didymos which is located at about 4 million miles from Eart in October 2022.
  • Scientists will observe the impact with telescopes and measure the change in the Didymoon’s orbit around the asteroid.
  • Scientists hope to move it by just a fraction of a per cent off its path, which is enough to deflect any future asteroids off course since Didymos poses no threat to Earth.

DART won’t be the first spacecraft to wallop an asteroid. Earlier this month, Japan’s Hayabusa2 probe smashed a copper cannonball into the space rock Ryugu, to unearth pristine subsurface material for study.
