Orb-1 Launch Postponed to Possibly Jan 9 Due to Space Radiation Environment

We received the following information via NASA 30 minutes ago.

In consultation with NASA, we are asking all SSEP delegations at Wallops Island to still proceed to the Visitor Center at 9:00 am for a 9:30 am media briefing.

More on the launch delay to follow later in the day as new information is available.

Early this morning the Antares launch team decided to scrub today’s launch attempt due to an unusually high level of space radiation that exceeded by a considerable margin the constraints imposed on the mission to ensure the rocket’s electronic systems are not impacted by a harsh radiation environment. The solar flux activity that occurred late yesterday afternoon has had the result of increasing the level of radiation beyond what the Antares engineering team was monitoring earlier in the day. Overnight, Orbital engineers who are experts in the field ran numerous models to ensure that all possibilities to preserve the launch were examined. However, due to significantly elevated flux levels, the Antares team decided to postpone the launch to spend the day further examining the potential effects of the space radiation on the rocket’s avionics suite.

Today, in consultation with NASA and outside experts in the field of “space weather,” Orbital will continue to monitor the levels of space radiation with a goal of setting a new launch date as soon as possible. If we are able to launch on Thursday, the launch targeted launch time would be 1:10 p.m. (EST), with Cygnus arriving at the ISS Sunday morning, January 12.

The Student Spaceflight Experiments Program (SSEP) is a program of the National Center for Earth and Space Science Education (NCESSE) in the U.S., and the Arthur C. Clarke Institute for Space Education internationally. It is enabled through a strategic partnership with DreamUp PBC and NanoRacks LLC, which are working with NASA under a Space Act Agreement as part of the utilization of the International Space Station as a National Laboratory. SSEP is the first pre-college STEM education program that is both a U.S. national initiative and implemented as an on-orbit commercial space venture.
