SpaceX delays make Spaceflight to find choice launches



WASHINGTON — Delays in SpaceX’s launch schedule have led an aggregator of secondary payloads to find alternative rides for dozens of satellites it planned to fly on a Falcon 9.
In a March 2 message, Curt Blake, president of Seattle-based Spaceflight, said that “significant” delays in the planned launch of the Formosat-5 mission on a Falcon 9 from Vandenberg Air Force Base in California forced the company to find alternative rides for nearly 90 satellites that were to launch as secondary payloads on a payload adapter called Sherpa.
“We learned our launch would occur potentially much later than expected,” Blake wrote, not giving a specific launch date. “While delays are inevitable in the launch business, we made the decision to rebook all our customers slated to launch on the FormoSat-5 mission.”
Formosat-5 and Sherpa were slated to launch on the Falcon 9 this past year but were postponed, in part due to Sept. 1 pad explosion of the Falcon 9 during arrangements for a static-fire test at Cape Canaveral. That halted all Falcon 9 launches for four . 5 months.

Blake, within an 2016 interview Oct, said Spaceflight was hanging around on the Falcon 9 go back to flight before obtaining a new launch night out, and at that time didn't expect a introduction before early on 2017. The business had advised the owners of the satellites never to ship those to Spaceflight for integration onto the Sherpa adapter until it received a confirmed start time frame from SpaceX.

SpaceX hasn't disclosed a start day for Formosat-5, or a great many other forthcoming launches from Vandenberg. SpaceX Leader Gwynne Shotwell, speaking at a Feb. 17 press meeting at NASA's Kennedy Space Centre, said the business acquired postponed another Falcon 9 introduction of Iridium satellites, from Vandenberg, from mid-April to mid-June "to complete the queue of people that contain been looking forward to a airfare since we were down previous September." The business hasn't discovered those customers.

Blake said that, given the extended delays, the company decided to find other rides for the satellites that were to fly on Sherpa. “It took a huge effort, but within two weeks, the team hustled to have all customers who wanted to be rebooked confirmed on other launches!” he wrote.
Spaceflight spokeswoman Jodi Sorensen said March 2 that most of the satellites that had been flying on Sherpa will be rebooked on one of two launches. One is on the company’s own dedicated Falcon 9 mission, dubbed SSO-A, scheduled to launch from Vandenberg later this year. The other is an unspecified “international launch” scheduled for this summer or fall.
Spaceflight has brokered launches of small satellites as secondary payloads on a number of different vehicles. That included nine cubesats that launched on an Indian Polar Satellite Launch Vehicle (PSLV) Feb. 14. Eight of the nine satellites were from Spire, a company deploying a constellation of cubesats for ship tracking and weather data. The ninth satellite was a cubesat from an Israeli university.
Blake, in a recent commentary, defended the use of PSLV, which developers of small satellite launchers in the U.S. have criticized for undercutting the market. “Contrary to popular belief, foreign launches are not less expensive than domestic ones” in part because of regulatory costs, he wrote in the SatMagazine op-ed.
In comments directed at President Trump, Blake called on the administration to avoid any making policy changes that would make it harder to launch on Indian or other non-U.S. rockets while the capacity in the domestic market grows. “We ask the current administration to allow these international launch options that are critical to the smallsat industry and to support the efforts and policies that expand — not restrict — access to space,” he wrote.
As for Sherpa itself, Sorensen said it could fly on the SSO-A mission or another launch with a different set of satellite payloads. “It’s completely flight ready, so if we can, we’ll definitely use it,” she said.
