On Thursday, a commercial Indian launch startup named Skyroot Aerospace unveiled its Dhawan-1 cryogenic engine to mark the 100th anniversary of Indian rocket pioneer Satish Dhawan.

The company said the engine is 100 percent 3D printed using additive manufacturing. It will be powered by liquified natural gas and liquid oxygen.

Satish Dhawan was an Indian aerospace engineer who was a pioneer experimental fluid dynamics research. He served as the third chairman of the Indian Space Research Organisation (ISRO). The nation’s spaceport is named after him.

Dhawan-1 will be used as the upper stage of Skyroot’s Vikram II booster. The company is developing three Vikram rockets to serve the small satellite launch market.

Vikrams will launch payloads ranging from 225 kg to 720 kg depending upon the rocket used and the orbit desired. Skyroot says the boosters can be assembled and launched within 24 to 72 hours with minimal infrastructure.

According to a story in the Economic Times, Skyroot was founded by three former ISRO employee who are looking to take advantage of India’s decision to allow private space companies to operate.

ISRO Successfully Tests Crew Escape System

SRIHARIKOTA, India (ISRO PR) — ISRO carried out a major technology demonstration today (July 05, 2018), the first in a series of tests to qualify a Crew Escape System, which is a critical technology relevant for human spaceflight. The Crew Escape System is an emergency escape measure designed to quickly pull the crew module along with the astronauts to a safe distance from the launch vehicle in the event of a launch abort. The first test (Pad Abort Test) demonstrated the safe recovery of the crew module in case of any exigency at the launch pad.

After a smooth countdown of 5 hours, the Crew Escape System along with the simulated crew module with a mass of 12.6 tonnes, lifted off at 07.00 AM (IST) at the opening of the launch window from its pad at Satish Dhawan Space Centre, Sriharikota today. The test was over in 259 seconds, during which the Crew Escape System along with crew module soared skyward, then arced out over the Bay of Bengal and floated back to Earth under its parachutes about 2.9 km from Sriharikota.

The crew module reached an altitude of nearly 2.7 km under the power of its seven specifically designed quick acting solid motors to take away the crew module to a safe distance without exceeding the safe g-levels. Nearly 300 sensors recorded various mission performance parameters during the test flight. Three recovery boats are being exercised to retrieve the module as part of the recovery protocol.
