SAN FRANCISCO — Planet Labs, the San Francisco company planning to establish the world’s largest Earth imaging constellation, announced Nov. 26 the successful launch of two satellites and shipment to Virginia of 28 additional spacecraft in preparation for their December launch.

On Nov. 21, Planet Labs sent triple cubesats Dove 3 and Dove 4 into polar orbit on a Dnepr rocket from Russia’s Yasny launch site. “The launch was extremely successful,” said William Marshall, Planet Labs co-founder and chief executive. “They went into precisely the orbit we wanted. We have also successfully made contact.”

The latest additions to the Planet Labs fleet offer improvements in the capability provided by the firm’s first satellites launched in April, Dove 1 and Dove 2, which also were triple cubesats measuring 10 centimeters by 10 centimeters by 30 centimeters.

Dove 3 and Dove 4 will demonstrate the firm’s latest technology, including upgraded communications, attitude control and observation technology. “We like to iterate our satellite designs very rapidly,” Marshall said. “It’s the same compact form factor as Dove 1 and Dove 2, but we have stuck in more capability.”

SES-8 Satellite Launch Will Be SpaceX’s Most Challenging To Date

SpaceX is preparing for its next big mission this evening when it will, for the first time, attempt to launch a telecom satellite into orbit. A successful launch could prove the Elon Musk-owned company’s worth as both a private and commercial powerhouse in the space launch game.

The launch window for SpaceX’s Falcon 9 opens today at 5:37 p.m. EST from Cape Canaveral, Florida. The rocket will be carrying a Luxembourg-based SES-8 satellite that will serve television customers in India and parts of Southeast Asia.

The launch of a satellite is not only a first for SpaceX, but will also be its most challenging. The Falcon 9 rocket must show its capabilities in launching the SES-8 satellite into a geostationary transfer orbit more than 22,000 miles over Earth’s equator.

Today’s launch of an upgraded Falcon 9 rocket, known as version 1.1, also comes after a September 29 test launch of the same rocket design in California. While that test was successful, an optional restart of the rocket’s upper stage engine, which will be necessary for the latest mission, failed to activate.

SpaceX later determined that an igniter line froze and believes that added insulation will prevent a repeat of the issue.

“We’ve done everything we can possibly think of to maximize the reliability of this launch,” Musk, CEO and chief designer at SpaceX, told BBC’s Jonathan Amos in an interview

“There’s no stone that hasn’t been turned over at least twice to maximize the probability of success. Being a rocket, there’s still some chance of failure, but whatever happens we can be at peace that we’ve done everything we could think of, and SES’s technical team has looked at it and they concur,” Musk added.
