T-minus 80 minutes. The Chandrayaan 2 mission is counting down to liftoff from the Satish Dhawan Space Center, located on Sriharikota Island on coast with the Bay of Bengal around 50 miles (80 kilometers) north of Chennai.

The stubby two-stage GSLV Mk.3 rocket is making its fourth flight today, following a suborbital demo flight in 2014 and a pair of successful orbital test flights in 2017 and 2018.

The GSLV Mk.3 uses a twin-engine core stage, uprated solid-fueled boosters, and an upgraded cryogenic hydrogen-fueled upper stage engine based on the Indian-made powerplant that flies on the smaller GSLV Mk.2 launch vehicle.



According to the Indian Space Research Organization, the GSLV Mk.3 can haul up to 8,800 pounds (4,000 kilograms) of payload to geostationary transfer orbit, the drop-off point for most communications satellites. For low Earth orbit missions going to altitudes of less than 400 miles (600 kilometers), the GSLV Mk.3 can deliver nearly 18,000 pounds (8,000 kilograms) of mass.

Those figures are just shy of the capability of United Launch Alliance's Atlas 5 rocket in its basic configuration without solid rocket boosters, but nearly twice as high as the performance of the GSLV Mk.2, the second-largest rocket in India's inventory.

Monday's liftoff is scheduled for 2:43 p.m. local time Monday in India from the Second Launch Pad at the Sriharikota spaceport.

The fully-fueled Chandrayaan 2 spacecraft weighs 8,547 pounds (3,877 kilograms).

The GSLV Mk.3 will blast off on the power of its two side-mounted S200 boosters, a larger version of the solid-fueled core motors used on India's smaller GSLV Mk.2 and Polar Satellite Launch Vehicle. Each booster contains 205 metric tons (450,000 pounds) of pre-packed solid propellant, and the two rocket motors combine to produce 2.2 million pounds of thrust at peak power.

The core stage's two Vikas engines, burning a mixture of hydrazine and nitrogen tetroxide will ignite at T+plus 1 minute, 50 seconds, when the GSLV Mk.3 is at an altitude of 27.2 miles (43.8 kilometers).

At T+plus 2 minutes, 11 seconds, the S200 boosters -- the second-largest solid rocket motors currently flying on a satellite launcher after the Ariane 5's strap-on boosters -- will burn out and jettison. The twin-engine core stage will continue firing as the GSLV Mk.3 soars on an easterly course from Sriharikota, before consuming its 116 metric tons (255,000 pounds) of liquid propellant at T+plus 5 minutes, 5 seconds.

The clamshell-like shroud covering the Chandrayaan 2 spacecraft will release during the core stage's burn at T+plus 3 minutes, 23 seconds, as the GSLV Mk.3 climbs into space.

Stage separation is expected at T+plus 5 minutes, 8 seconds, followed by ignition of the upper stage's advanced hydrogen-fueled CE-20 engine, a more powerful version of the Indian-built cryogenic engine on the GSLV Mk.2.



The CE-20 engine is programmed to fire for nearly 11 minutes until T+plus 15 minutes, 59 seconds.

The on-board computer is targeting an elliptical transfer orbit with a low point of 105 miles (170 kilometers) and a high point of 24,308 miles (39,120 kilometers).

Separation of the Chandrayaan 2 spacecraft from the GSLV Mk.3's upper stage is scheduled for T+plus 16 minutes, 14 seconds.

Indications are that everything is going as planned. Less than 45 mins now for #Chandrayaan2 launch.
