An Indian rocket will launch an ocean-observing satellite and eight tiny ride-along spacecraft early Saturday (Nov. 26), and you can watch the action live.
A Polar Satellite Launch Vehicle (PSLV) rocket is scheduled to lift off Saturday at 1:26 a.m. EST (0626 GMT; 11:56 a.m. India Standard Time) from Satish Dhawan Space Centre, on India’s southeast coast.Â

If all goes according to plan, the four-stage, 146-foot-tall (44 meters) PSLV will deploy the primary payload, Earth Observation Satellite-06 (EOS-06), just over 17 minutes after liftoff, about 462 miles (743 kilometers) above Earth.
The 2,463-pound (1,117 kilograms) EOS-06 is the third spacecraft in India’s Oceansat series. The satellite will use three science instruments to monitor sea surface temperatures and other ocean characteristics for at least five years. EOS-06 also carries a fourth instrument that will help beam data back to Earth.Â
After dropping off EOS-06, the PSLV’s upper stage will perform a series of maneuvers, descending to deploy the eight small satellites at an altitude of about 323 miles (520 km). The first of these passengers will separate about 114 minutes into flight, and the last will deploy roughly six minutes later.
These piggyback craft are a diverse bunch. For example, four of them are “Astrocast” cubesats, spacecraft about the size of a loaf of bread that will demonstrate “internet of things” technology, according to an ISRO mission description (opens in new tab).Â
Another one, called Anand, will “demonstrate the capabilities and commercial applications of [a] miniaturized Earth-observation camera” in low Earth orbit, ISRO officials added.
Saturday’s mission will be the 56th PSLV flight. The rocket is India’s medium-lifter, capable of delivering up to 3,650 pounds (1,750 kg) of payload to sun-synchronous polar orbit.
India also operates a heavy lifter called the Geosynchronous Satellite Launch Vehicle (GSLV), which can haul 17,640 pounds (8,000 kg) to low Earth orbit. The nation also just debuted its Small Satellite Launch Vehicle (SSLV), but things didn’t go according to plan; the rocket failed to deliver its payloads to the proper orbit during its inaugural mission in August.
