DARPA trying to launch smallsat experiment on an Indian rocket
Informing about the plans to create world class infrastructure in India through 100 smart cities; metro projects for 50 cities; modern waste management system for 500 cities; and a roof over every head by 2022, Modi invited Qatar to be a partner in India’s growth story.
After creating existential problems for India’s greatest painter M. F. Husain for expressing his honest displeasure in aesthetic language over the practice of making anything and everything a fanatic subject like mother, etc, Indian regime, then controlled by the Congress party, had dispatched him to Qatar in asylum where he died an unhappy man. India has conveniently forgotten him after that.
Modi and Sheikh Tamim held detailed talks here on a wide range of issues with an intent to give a push to India-Qatar ties.

But the continued delay of that mission forced Spaceflight this March to seek out alternatives for Sherpa customers .
Speaking at the Milsatcom USA conference here June 29, Jeremy Palmer, program manager for DARPA’s Tactical Technology Office, said the agency is now pursuing a launch opportunity with the Indian Space Research Organisation (ISRO).
“We have 14 of these satlets aggregated together in a 155-kilogram secondary payload satellite intended for low-Earth orbit at an inclination of 98 degrees with an elliptical orbit of 450-kilometer perigee,” he said. “We hope to launch EXCITE aboard an Indian PSLV rocket in the early half of FY18.”
DARPA’s desire to launch on an Indian rocket is ironic given the U.S. government’s ban on allowing companies to launch U.S. satellites on such vehicles unless given express permission through a waiver .
Palmer acknowledged that there are regulatory challenges facing DARPA as well in seeking to launch on PSLV, but the agency feels “that there is a path forward.”
“That is a continuing challenge but we feel that challenge is surmountable,” he said, without giving explanation as to how they would be overcome.
The DARPA satlets are modular small satellites each 10 centimeters high and 20 centimeters square with a mass of 7.5 kilograms, according to Palmer. Each satlet contains its own systems for propulsion, power, attitude control, and memory. Space technology startup Novawurks is building the spacecraft using its Hyper-Integrated Satlet, or HISat, product.
DARPA’s EXCITE mission is to demonstrate the ability to build a satellite bus like a biological cellular system, using the satlets to form a unique bus around a payload, such as a sensor. Because each satlet has all the necessary systems to function in space, they provide redundancy in the event that some fail. Palmer said the satlets could make a satellite bus anywhere from a few tens of kilograms to 2,000 to 3,000 kilograms. At one point, EXCITE was part of DARPA’s Phoenix program for servicing satellites, but it is now a separate program, he said.
Palmer said the mission will include several high-value payloads with user-defined adaptors including a multicore processor experiment, radios, a pathfinder telescope and other environmental monitoring sensors. Cubesat manufacturer Pumpkin is supplying “snap-on” solar wings. The EXCITE mission will also have a free-flyer telescope, Palmer said.
