Name the giant asteroid which will fly past Earth on April 13, 2029.

ISRO will launch a student satellite called 'Kalamsat' and an imaging satellite known as 'Microsat-R' on 24 January 2019. Both the satellite will be carried by 'PSLV C-44' rocket. PSLV is a four-stage launch vehicle. In PSLV-C44, the fourth stage (PS4) of the vehicle would be moved to a ?higher circular orbit so as to establish an orbital platform for carrying out experiments.

An international team of astronomers used the NASA/ESA Hubble Space Telescope to study white dwarf stars within the globular cluster NGC 6752.

Board of Control for Cricket in India (BCCI) announced cash awards of Rs 15 lakh per match for each of the playing eleven that featured in India's maiden Test Cricket series win on Australian soil. Virat Kohli and his team defeated Australia 2-1 in the four-match Test series, ending India's 71-year-old wait for the rare achievement. Congratulating the team, the BCCI also announced cash awards of seven and a half lakh rupees for all the reserve players, as well as the members of the support staff.

The National Aeronautics and Space Administration (NASA)'s Hubble Space Telescope ejected measurements validate that the Universe is expanding about 9% faster than expected based on its trajectory seen shortly after the big bang. It was published in Astrophysical Journal Letters on April 25.The researchers using Hubble as a "point-and-shoot" camera to look at groups of Cepheids using a new method called DASH (Drift And Shift), while Hubble can observe one star for every 90-minute orbit around Earth.Adam Riess, Bloomberg Distinguished Professor of Physics and Astronomy at The Johns Hopkins University, Nobel Laureate and the project's leader,is the first author of the research.

The first nuclear test Pokhran with a codenamed as 'Smiling Buddha' was carried out in May 1974. The second test conducted was Pokhran II which was a series of five tests of nuclear bomb explosions, administered by India at the Pokhran Test Range of Indian Army in May, 1998. Pokhran II comprised of five detonations out of which the first one was a fusion bomb while the other four were fission bombs. These nuclear tests evolved various sanctions against India by many major states, including the United States and Japan.

India's lunar mission Chandrayaan 2 will carry NASA's laser instruments. The U.S. space agency said that the laser instrument will help scientists to make precise measurements of the distance to the Moon. Chandrayaan 2 is scheduled to be launched in the month of April. NASA has confirmed that Chandrayaan 2 and Israeli lander Beresheet, due to touch down on April 11, will each carry NASA-owned laser retroreflector arrays. Chandrayaan-2 will be India's second mission to the Moon. It will include an orbiter and lander-rover module.

By using Indian multi-wavelength space observatory AstroSat, the astronomers from Thiruvananthapuram and Mumbai have identified a new population of ultraviolet stars in the globular cluster NGC 2808. Globular clusters are collections of thousands to millions of stars, moving as one unit. These stars are tightly held together by gravity of the cluster itself, and are believed to have formed together at roughly the same time. The NGC 2808 is one of the most massive globular clusters that we know of, and is located at a distance of 47,000 light years from us. This cluster was observed by the team of researchers using the UltraViolet Imaging Telescope (UVIT) on-board AstroSat. So far, AstroSat has taken images of over 2,000 individual stars in NGC 2808 through various ultraviolet filters. AstroSat is the India's first dedicated multi wavelength space observatory. It was launched in September 2015. It orbits in low earth equatorial orbit at altitude of 650 km and has mission life of 5 years. It observes universe in the optical, Ultraviolet (UV), low and high energy X-ray regions of the electromagnetic spectrum.

SpaceX launched the U.S. Air Force's newest 'GPS III' satellite on a Falcon 9 rocket from Cape Canaveral Air Force Station in Florida, USA. The solar-powered spacecraft, dubbed "Vespucci," is the company's first official "National Security Space" mission. Vespucci's nickname honours Italian cartographer and explorer Amerigo Vespucci, after whom North and South America were named. It was competed through the Air Force's Evolved Expendable Launch Vehicle program. The successful GPS III SV01 mission marked SpaceX's 21st and final launch of 2018, beating the company's 2017 flight rate of 18 launches.

In the special mission, Indian Space Research Organisation (ISRO) will also launch 28 third-party satellites and will demonstrate its new technologies like three different orbits with a new variant of 'Polar Satellite Launch Vehicle' (PSLV) rocket in March, 2019. Electronic intelligence satellite 'Emisat' of Defence Research and Development Organisation (DRDO) weighs about 420 kg. After launching Emisat at an altitude of 763 km, the PSLV rocket will be brought down to put the remaining 28 satellites into orbit at an altitude of 504 km.

India's latest communication satellite GSAT-31 was successfully launched by European launch services provider- Arianespace's rocket from Kourou Launch Base in French Guiana on February 6, 2019. The Ariane-5 vehicle (Flight VA247) also carried Saudi Geostationary Satellite 1/Hellas Sat 4 along with GSAT-31.
