India''s heavy lift rocket Geosynchronous Satellite Launch Vehicle - Mark III (GSLV Mk III), nicknamed as ''Bahubali'', and its passenger Chandrayaan-2 were being readied up for their historic flight to the Moon on July 15, said space agency officials. "Preparations are going at a hectic pace at the Satish Dhawan Space Centre in Sriharikota for the July 15 early morning launch at 2.51 a.m. Everything is progressing normally," said an official of Indian Space Research Organisation (ISRO). About 16 minutes into its flight, the Rs 375 crore GSLV Mk III rocket will put into orbit the Chandrayaan-2 spacecraft. While ISRO officials call the 640-tonne GSLV Mk III rocket as ''fat boy'', the Telugu media nicknamed it ''Bahubali'', as like the hero in the successful film lifts a heavy Lingam, the rocket will carry the 3.8-tonne Chandrayaan-2 spacecraft. According to the ISRO, the Chandrayaan-2 will be injected into an Earth parking 170x40400 km orbit. The spacecraft''s orbit will be raised by a series of manoeuvres to put it on Lunar Transfer Trajectory. On entering the Moon''s sphere of influence, on-board thrusters will slow down the spacecraft for Lunar Capture. The Rs 603 crore Chandrayaan-2 consists of three segments - the Orbiter, the lander-Vikram and rover Pragyaan. The Indian space agency has named lander Vikram in memory of country''s space pioneer Vikram Sarabhai and rover Pragyaan means wisdom in Sanskrit. According to ISRO, on the day of landing, the lander Vikram will separate from the Orbiter and then perform a series of complex manoeuvres comprising rough braking and fine braking. Imaging of the landing site region prior to landing will be done for finding safe and hazard-free zones. The Vikram is expected to finally land near South Pole of the Moon on September 6, 2019 and carry out three scientific experiments. The Indian space agency said the lander will get separated from the Orbiter four days after the former enters the lunar orbit. Vikram will soft land from a height of 100 km from the Moon''s surface. Subsequently, the six-wheeled rover Pragyaan will roll out and carry out two experiments on lunar surface for a period of one lunar day which is equal to 14 Earth days. The Orbiter with eight scientific experiments will continue its mission for a duration of one year. The mission also has one passive experiment from the US space agency NASA. The Indian space agency said the mission will also try to unravel the origins of the Moon. Interestingly, the lander as well as the rover will have the Indian national flag painted on them. Ashoka Chakra will be imprinted on the rover''s wheels. The success of Chandrayaan-2 mission will make India the fourth country in the world to land and ride on the Moon surface after the US, Russia and China. India launched its first Moon mission Chandrayaan-1 in October 2008 using its light rocket Polar Satellite Launch Vehicle (PSLV). Source: IANS News Agency
NASA SLS rocket testing ensures astronaut safety, mission success Huntsville AL (SPX) Jul 11, 2019 As the world reflects on the 50th anniversary of the Apollo missions, NASA is looking forward to its next giant leaps. One way NASA ensures the safety of astronauts and the success of the Artemis missions to the Moon in preparation for future missions to Mars is by testing the Space Launch System (SLS) rocket structures. With the recent delivery of the last structural test article, the liquid oxygen tank, to NASA's Marshall Space Flight Center in Huntsville, Alabama, and the start of testing in Ju ... read more
