Live coverage: Indian rocket set to launch 31 satellites
November 28, 2018 | Stephen Clark

11/29/2018 05:17 Spaceflight Now

The countdown is on for the launch of an Indian rocket at 0428 GMT Thursday (11:28 p.m. EST Wednesday) with 31 satellites from nine countries, with most of the smallsats coming from U.S. customers.

The Polar Satellite Launch Vehicle is standing on the First Launch Pad at the Satish Dhawan Space Center on India's southeastern coast, ready for liftoff on a nearly two-hour mission to deploy the 31 payloads at two different altitudes.

The main satellite launching on the PSLV is HysIS, an 837-pound (380-kilogram) Earth-observing spacecraft for the Indian Space Research Organization.

Equipped with an Earth-facing imager capable of collecting data at numerous wavelengths across the visible, near-infrared and shortwave infrared spectra, HysIS will take pictures rich in detail, allowing analysts to distinguish between soil and vegetation types, pollution and urban infrastructure.

ISRO says the satellite will be useful in agriculture, forestry, soil and geological surveys, coastal zone surveillance, environmental monitoring and pollution detection.

The four-stage PSLV will fly toward the southeast from the launch base on Sriharikota Island, then turn on a southerly track to avoid flying over Sri Lanka.

The 144-foot-tall (44.4-meter) rocket will blast off with more than a million pounds of thrust from its solid-fueled first stage. The PSLV is not flying with the six strap-on motors that typically give the rocket an extra boost because the payloads aboard the launcher are relatively lightweight.

The first stage will fire for 1 minute, 50 seconds, before exhausting its propellant and separating to fall into the Bay of Bengal. A second stage Vikas engine, fueled by liquid hypergolic propellants, will ignite for roughly two-and-a-half minutes, then jettison to allow a solid-fueled third stage to light.

The rocket's clamshell-like payload shroud is scheduled to peel away during the second stage burn, as the Vikas engine produces about 180,000 pounds of thrust.

The third stage motor will ignite and burn nearly four minutes. The fourth stage, powered by two hydrazine-fueled thrusters producing around 3,400 pounds of thrust, will then take over for a firing to inject the mission's satellite passengers into a roughly circular sun-synchronous polar orbit at an altitude of 395 miles with an inclination of approximately 97.96 degrees.

The HysIS satellite will separate in that orbit at T+plus 17 minutes, 21 seconds.

But the mission isn't over at that point. Two more firings of the PSLV fourth stage are planned at T+plus 59 minutes, 39 seconds, and at T+plus 1 hour, 47 minutes, 43 seconds, to maneuver the rocket and the remaining satellites into a lower 313-mile-high (504-kilometer) orbit inclined 97.47 degrees to the equator.

Each restart of the fourth stage should last around four seconds.

The pre-programmed sequence to release the 30 secondary payloads should begin at T+plus 1 hour, 49 minutes, 1 second, and conclude with the final spacecraft separation event at T+plus 1 hour, 52 minutes 47 seconds.

The 30 smallsats aboard the PSLV mission, codenamed PSLV-C43, include 16 Flock-3r Dove CubeSats, each about the size of a shoebox, built and owned by Planet, a San Francisco-based company with a fleet of more than 100 smallsats dedicated to Earth-imaging.

Another four satellites aboard the launch come from Spire Global, another San Francisco company. The four shoebox-sized Lemur-2 CubeSats will join Spire's constellation of commercial weather monitoring and ship tracking satellites.

BlackSky, a subsidiary of Seattle-based Spaceflight Industries, has a 123-pound (56-kilogram) Earth-imaging microsatellite riding on the PSLV. The BlackSky Global 1 satellite is a follow-up to a pathfinder craft launched in 2016 to test out technology for the company's planned fleet of commercial Earth observation satellites.

"This is an important milestone for Spaceflight Industries and for our BlackSky geospatial information business," said Jason Andrews, chairman and CEO of Spaceflight Industries, in a press release earlier this year. "Qualifying the Global generation of spacecraft paves the way for mass production and launch of our full constellation, as well as achieving our vision of deploying a high revisit rate constellation in the near future."

Another California-based company, GeoOptics, is also launching a small satellite for its own commercial weather monitoring constellation, which monitors GPS navigation signals passed through the atmosphere to measure temperature and moisture profiles. The GeoOptics CICERO 8 satellite weighs around 22 pounds (10 kilograms).

The HSAT 1 CubeSat, funded by Harris Corp., will test a deployable antenna design for potential use on future smallsats.

A CubeSat named CASE owned by Kepler Communications, a Canadian company, is also hitching a ride to orbit. CASE is a testbed for Kepler's planned constellation of commercial data relay nanosatellites in low Earth orbit.

Fleet Space Technologies, an Australian company with plans to build its own network of tiny tracking and data relay satellites designed to connect with devices in remote locations on Earth, is also launched its third test CubeSat, named Centauri 1.

A Dutch company named Hiber Global is pursuing a similar data connectivity market, and its first tech demo CubeSat -- Hiber 1 -- is aboard the PSLV.

The Colombian Air Force's first satellite, FACSAT 1, launching from India carries a medium-resolution Earth-imaging camera on a toaster oven-sized spacecraft bus.

The Finnish company Reaktor Space Lab is launching its first satellite, a CubeSat, with a prototype infrared hyperspectral imager, the first of its kind to fly on such a small commercial spacecraft.

The Malaysian-built InnoSat 2 CubeSat and 3Cat 1, developed by students at Universitat Politècnica de Catalunya in Barcelona, are also slated for launch.

The launch will mark the first from India with satellites for Australia, Colombia, Malaysia and Spain, which join 28 other countries which have launched payloads on Indian rockets.
