Solar Orbiter

NASA, ESA (European Space Agency), Airbus and United Launch Alliance now are targeting 11:03 p.m. EST Sunday, Feb. 9, for the launch of the Solar Orbiter mission on an Atlas V rocket from Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida. The launch has a two-hour window. The two-day launch delay was caused by two items that delayed transport of the spacecraft to the pad. The first item was a schedule conflict on Wednesday with a commercial mission launch from a nearby launch pad. The second item was the weather Thursday morning.

NASA, ESA (European Space Agency) and United Launch Alliance (ULA) have adjusted the launch date of the Solar Orbiter spacecraft to Friday, Feb. 7, from Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida due to the rescheduling of the mission’s Wet Dress Rehearsal. Solar Orbiter will launch aboard a ULA Atlas V rocket from Space Launch Complex 41. The two-hour launch window opens at 11:15 p.m. EST. Solar Orbiter is an international cooperative mission between ESA and NASA. The spacecraft has been developed by Airbus Defence and Space.

The payload fairing that will provide a protective, aerodynamic cover for Solar Orbiter during launch is now in place. The two halves of the United Launch Alliance Atlas V fairing were moved into position and installed around the spacecraft on Jan. 20 inside a cleanroom at Astrotech Space Operations in Titusville, Florida.

The rocket that will launch a new spacecraft to study the Sun is beginning to take shape at Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. The first-stage booster for the United Launch Alliance Atlas V rocket is "on stand," meaning it has been raised to a vertical position inside the complex's Vertical Integration Facility. In the coming days, the one solid rocket booster needed for the mission will be added to the booster, followed by the single-engine Centaur upper stage.
