ISRO Chairman Dr. K Sivan has announced that the organization is well prepared to meet the targets of launching Gaganyaan manned mission to outer space by December 2021. Under Gaganyaan project, India is planning to send three astronauts to outer space for seven days and bring them back. 332 launches are planned this year. Important among them are Chandrayaaan -2 mission to the moon in mid-April. GSAT-20 Satellite for high bandwidth connectivity to be launched in September-October.

3 astronauts, Nick Hague and Christina Koch from US and Alexey Ovchinin from Russia arrived at the International Space Station (ISS) on Russian Soyuz spacecraft which was launched from Kazakhstan's Baikonur Cosmodrome on 14th March 2019. Soyuz spacecraft carries people and supplies to and from International Space Station and it has become the sole means of transportation after the retirement of Space Shuttle in 2011.

China lifted its broadband communication system by launching a Long March - 3B carrier rocket with 'ChinaSat 6C' into a geostationary orbit in Sichuan province. The'ChinaSat 6C' was launched from Xichang Satellite Launch Center in Sichuan province. It is a 19 story tall rocket which is expected to provide high quality radio and television transmission services. It marked 300th launch of the Long March carrier rocket series which was developed by the China Aerospace Science and Technology Corporation and will be operated by China Satellite Communications Co. Ltd. The satellite will cover China, Australia, New Zealand and the South Pacific Island Countries. Nearly 97% of China's total launch missions was on Long March rocket series.

NASA's OSIRIS-REx spacecraft broke a record after successfully entering into orbit around the asteroid Bennu - the smallest cosmic object ever to be orbited by a spacecraft. NASA's OSIRIS-REx spacecraft, 110 million kilometers away, carried out a single, eight-second burn of its thrusters. The manoeuvre placed the spacecraft into orbit around the asteroid Bennu. The spacecraft will circle Bennu about 1.75 kilometres from its centre, closer than any other spacecraft has come to its celestial object of study.

The Indian Space Research Organisation (ISRO) has recently launched Samwad with Students as part of its outreach programme. The Indian Space agency will engage youngsters across the country in activities concerning space science under this programme. The new conversation mission will inspire students cutting across schools and colleges. During the inauguration in Bengaluru, 40 students and 10 teachers from select schools interacted with ISRO Chairman Dr. K Sivan about the Indian Space Programme and their benefits to the common man.

Recently, Indian and the US navies conducted joint submarine hunting exercise near Diego Garcia in the Indian Ocean in which India's P8I Neptune Aircraft and US P-8A Poseidon maritime patrol aircraft along with the USS Spruance have participated. The objective of this exercise is to lay the groundwork for coordinating maritime patrol and reconnaissance.The Indian P-8I anti submarine aircraft which participated in the exercise is from Naval Air Squadron 312 based at Naval Station Rajali in Arakkonam, Tamil Nadu and US P-8A Poseidon aircraft which participated in the exercise is from Patrol Squadron VP-8 'Fighting Tigers', based in Jacksonville, Florida.

NASA's first mission to demonstrate a planetary defence technique, The Double Asteroid Redirection Test (DART), will get one opportunity to hit small moonlet in the binary asteroid system Didymos. The asteroid poses no threat to Earth and is an ideal test target. NASA revealed that details about its plan to hit a small moonlet target in a double asteroid system with a spacecraft in 2022. The asteroid, called Didymoon or Didymos B, is a moon asteroid around 150 meters tall orbiting a larger body Didymos A, the most accessible asteroid of its size from the Earth.

21 light years away on december 22, 2018 in the constellation Cassiopeia, a shimmering "super-Earth", five times the mass of Earth, dubbed as HD219134 b was discovered. Unlike the Earth, however, it most likely does not have a massive core of iron, but is rich in calcium and aluminium alongside magnesium and silicon. It shimmers red to blue like rubies and sapphires, because these gemstones are aluminium oxides which are common on the exoplanet. According to the researchers it is one of three candidates likely to belong to a new exotic class of exoplanets. The other two exoplanets studied were 55 Cancri e and WASP-47 e. The study was published in the journal Monthly Notices of the Royal Astronomical Society: Letters.

Astronomers Captured the First Image of a Black Hole which was a halo of dust and gas, tracing the outline of a colossal black hole at the center of the galaxy M87 (Messier 87) with the help of The Event Horizon Telescope (EHT) observations. Black Hole.Black holes were first predicted by Einstein's theory of relativity and these are the extreme cosmic objects, containing incredible amounts of mass within a tiny region.The galaxy is 55 million light-years away from Earth.
