Raavana-1: Sri Lanka’s 1st satellite successfully launched

Sri Lanka’s first ever satellite ‘Raavana-1’, designed and developed by two Sri Lankan engineers, was successfully placed into orbit. It was launched from International Space Station (ISS) along with two other BIRDS 3 satellites from Japan and Nepal.

About Raavana-1

Background: The satellite was officially handed over to JAXA (Japanese Aerospace and Exploration Agency) on February 18 and was sent to International Space Station on April 17, through assistance of Cygnus-1 spacecraft from United States.

Orbit: It was deployed to 400-km of orbit at an inclination of 51.6 degrees using JAXA (Japanese Aerospace and Exploration Agency) owned Kibo experiment module.

Engineer: It was designed and developed by two Sri Lankan engineers Tharindu Dayaratne and Dulani Chamika who are studying space engineering at Japan’s Kyushu Institute of Technology.

Features: It is a cube satellite measuring 11.3 cm x 10 cm x 10 cm, and weighs around 1.05 kg. It is expected to fulfil 5 missions including capturing pictures of Sri Lanka & its surrounding regions. It also has active attitude stabilization which will ensure that satellite’s attitude is stable under influence of external talks.

Life span: It is designed for a minimum lifespan of 1.5 years but is expected to be active for about five year.

About BIRDS 3 Project

The ‘Birds project’ is an acronym for ‘Joint Global Multi-Nation Birds Satellite project’, which is a cross-border interdisciplinary satellite project for non-space faring countries supported by Japan. It is first step towards creating an indigenous space program by designing, building, operating, testing and launching 1st satellite for participating nations.

The Birds 3 project is led by Japan’s Kyushu Institute of Technology and involves students from Sri Lanka, Nepal and Japan.

Fact Sheet: India to have its own Space Station

K. Sivan, Chairman of Indian Space Research Organisation (ISRO) recently announced that the country is planning to launch its own space station and modalities for it will be worked out after Gaganyaan Mission (India’s maiden manned mission to space).

Key Highlights

Mastering Technology: Although ISRO made announcement of space station recently but it has been quietly working on a key technology such as space docking & berthing technology for which it has also got Rs.10 crore sanctioned earlier. Once the agency will master this technology it will help join two separate free-flying space vehicles and also transfer materials and humans from one another that will enable this future space station and is also the key for a space station.

Extension: India’s space station project will be an extension of Gaganyaan Mission, which involves sending three Indian astronauts to space for 7 days in lower earth orbit (of 120-400 km). The government has already approved a cost of Rs.10,000 crore for Gaganyaan mission. Before the maiden flight with crew sometime in August 2022, there would be two unmanned (without crew) flights from Sriharikota, Andhra Pradesh.

The detailed project report on setting up India’s space station will also be submitted to government after Gaganyaan.

No Collaboration: India will not be collaborating with any other country for its space station project. United States (US), Russia, China and a consortium of nations that own the International Space Station (ISS) are the only countries that have had space stations so far. After its successful launch India would become 4th country to launch a space station.

Features:

The proposed space station is anticipated to weigh about 20 tonnes, it would be placed in an orbit 400 km above earth and will serve as a facility where astronauts can stay for upto 15-20 days in space.

India is targeting 2030 as the date to launch country’s space station which will most likely be used to conduct microgravity experiments.

It is one of the most ambitious projects ever undertaken by India.

What is a space station?

It is a spacecraft that designed to remain in space for an extended period of time and can be used for other spacecraft to dock as well as capable of supporting crew members, the most commonly known being the International Space Station (ISS).

International Space Station: It is a habitable artificial satellite in low earth orbit (LEO). It is the largest human-made body in LEO that completes multiple orbits around Earth every day thus can often be seen with the naked eye from Earth. Its first component was launched into orbit in 1998 and since then it has been inhabited continuously.
