SpaceX launched a rocket carrying the first 60 satellites of its ‘Starlink’ constellation, from Cape Canaveral, Florida in US. The SpaceX’s new array of Starlink communication satellites is intended to provide Internet from space
- Launch Vehicle: The launch was conducted by SpaceX’s Falcon 9 rockets which began to release the satellites at an altitude of 280 miles (450 kilometers).
- Orbit Position: The satellites later separated and used their thrusters to take up their positions in a relatively low orbit of 340 miles (550 kilometers).
- The satellite orbit is slightly higher than International Space Station (ISS), but below the majority of terrestrial satellites placed. The highest of terrestrial satellites sit in a geostationary orbit of 22,400 miles (36,000 kilometers).
- Satellite Features: Each of satellites weighs only 500 pounds (227 kilograms). They were built in-house in Redmond, near Seattle in US. Their weight makes them the heaviest payload carried aloft by SpaceX to date.
- Starlink’s constellation: will become operational once over 800 satellites will be activated, which will require at least 12 launches carrying similar payloads. The 60 launched satellites are among the first of a planned 12,000-satellite megaconstellation with aim to provide high-speed internet service from space to customers around the globe.
- Significance: This launch made SpaceX an early forerunner, along with its rival OneWeb, a startup, but way ahead of Amazon’s Project Kuiper, the brainchild of Jeff Bezos.
- The US California-based Space Exploration Technologies, or SpaceX is a private rocket company of high-tech entrepreneur Elon Musk. Musk is also chief executive officer (CEO) of automaker Tesla Inc.
- When it comes to rocket launches it is leading the private space race.
- With its Starlink venture the firm is now looking to seize a chunk of future space internet market.
SpaceX successfully launched a Dragon spacecraft on a cargo mission for NASA to International Space Station (ISS).
- 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).
