ISRO to launch 9 satellites for US
Indian Space Research Organisation (ISRO) will be launching nine nano/
micro satellites for United States during 2015-16 time frame. This will
be the first time that ISRO will launch a US satellite.
"As on date, Antrix Corporation Ltd, the commercial arm of ISRO, has
signed an agreement to launch about nine nano/micro (US) satellites
during the 2015-2016 time frame,"
These satellites will go as piggyback on
PSLV's (Polar Satellite Launch Vehicle), officials said.So far,
45 satellites belonging to international customers from 19 countries
have been launched successfully by ISRO's satellite launch vehicles.
The first Reusable Launch
Vehicle-Technology Demonstration (RLV-TD) would be held during the end
of this year.
"The first RLV technology demonstration will be held
in the end of 2015".
RLV-TD is a
series of technology demonstration missions that have been considered as
a first step towards realising a Two Stage To Orbit (TSTO) fully
re-usable vehicle.
The fully indigenous
developed Geo-synchronous Satellite Launch Vehicle (GSLV) D6 would
be launched by end of this month, adding the cost of the 2.5 tonne
vehicle would be around Rs 250 crore.
The launch of GSAT 6 is expected to give a huge impetus in the field of the communication sector in the country.
RS 25 - FERRARI OF ROCKET ENGINES
NASA has once again tested an engine that is known as the Ferrari of
rocket engines. This RS-25 rocket is very complex and NASA had burned
few before learning how to get them started. NASA has called it one of
the most complex and efficient rocket engines in the world.
Making of this super powerful engine is a part of NASA’s plans to take the humanity to Mars. This is the overall sixth of the seven tests and NASA is looking for collecting information about the Ferrari of rocket engine’s controllers. These total seven tests are designed to put the upgraded space shuttles through the rigorous pressure and temperature conditions.
This RS-25 engine, aboard the SLS rocket, is the beast that will take us to the Mars one day. At the time of final launch to the Mars, SLS will take four RS-25 engines together, making it the most powerful rocket ever sent into the space.
The initial version of SLS stands 321 feet (98 meters) tall and is capable of taking 77 tons (70,000 kilograms) weight to the low Earth orbit. Apart from this, NASA will also make an evolved version 384 foot tall (117m) with 143 tons (130,000) capacity.
RS 25 rocket engine test
During the test, the RS-25 burned for 535 seconds during the test.
During the test, it surely looks incredible- but NASA will be performing
more tests to analyze the data and prepare itself for the final launch.
