China has launched its first solar exploration satellite into space to study the violent and sudden physical processes behind solar flares. The 550 kg (121-pound) satellite named Xihe (Name of Sun God in Chinese mythology) was launched by the Long March-2D rocket.
The three-person crew are expected to spend six months in space, to set up a new record for the time spent in space by Chinese astronauts.
Researchers have found evidence that Pluto's atmosphere is undergoing a dramatic alteration and is starting to disappear as the dwarf planet moves farther away from the Sun.
Jezero crater is known to be a dry, wind-eroded depression on the surface of Mars.
The US space agency NASA has launched a first-of-its-kind mission called 'Lucy Mission' to study Jupiter's Trojan asteroids.
Union Minister for Health and Family Welfare J P Nadda launched new Pneumococcal Conjugate Vaccine(PCV) for Pneumonia. It will provide protection against 13 types of pneumococcal bacteria which results in pneumonia. This is used to vaccinate children under two years old as part of the NHS childhood vaccination programme.
National Aeronautics and Space Administration( NASA) scientists detected "a strong water signature" in the atmosphere of a distant Neptune-sized planet called HAT-P-26b. HAT-P-26b has a primitive atmosphere composed entirely of hydrogen and helium.It is located about 437 light-years away, HAT-P-26b orbits a star roughly twice as old as our Sun.
India launched the Geosynchronous Satellite Launch Vehicle (GSLV-F09) carrying the GSAT-9 or the "South Asia" satellite on 5 May with the total weight of 2,230 kg. Initially, it
was to be named "SAARC Satellite" but its name was changed to South Asia Satellite after Pakistan refused to join the project. It was launched from the Satish Dhawan Space
Centre in Sriharikota in Andhra Pradesh. The satellite is meant for providing communication and disaster support and connectivities among the countries of South Asia region.
China has set up a 160-square-meter (1,720-square-foot) laboratory called as "Yuegong-1", or "Lunar Palace" for simulating a lunar-like environment to test a life-support system that may allow future astronauts to spend longer periods of time in space.
Surface-to-air Python and DERby(Spyder) missile system was test fired from the mobile launching complex-III of the Integrated Test Range (ITR) at Chandipur, Odisha. The defence system comprises two missiles - Python and Derby with an active onboard radar which makes the Spyder system more lethal. Both the missiles are smokeless which makes it harder to detect them visually and the launch position.
