ЦитироватьAtlas V rocket assembled for Solar Orbiter launchJan 8, 2020, 14:30 PMThe Atlas V rocket has been stacked to launch Solar Orbiter, an international spacecraft bound for the inner solar system to gain unprecedented insights into the lifestyle of the sun.A busy week of operations at ULA's Vertical Integration Facility (VIF) at Cape Canaveral Air Force Station kicked off the new year by bringing together the Atlas V rocket's first stage, single solid rocket motor and Centaur upper stage aboard the Mobile Launch Platform (MLP).Engineers gave approval for the pre-launch milestone known as LVOS, or Launch Vehicle on Stand, during a readiness review on Friday, Jan. 3.That authorized the first stage to be hauled fr om the Atlas Spaceflight Operations Center (ASOC) to the VIF on Monday morning, Jan. 6. Cranes lifted the 107-foot-long stage from its ground transportation equipment and rotated it vertically for maneuvering through the VIF doorway and alignment on the MLP.The next day, Jan. 7, the 100,000-pound strap-on solid rocket booster was brought to the VIF, pulled from its erector device and secured to the north-facing side Atlas V first stage.The basic build up of the rocket was completed today, Jan. 8 as the pre-integrated assembly known as OVI, or Off-site Vertical Integration, arrived at the VIF for hoisting atop the first stage. The OVI is comprised for the interstage, Centaur upper stage and base of the payload fairing.In the coming days, the launch vehicle will be powered up, its flight controls tested and engine nozzles gimbaled, and a simulated launch sequence conducted before the MLP transports the rocket to the pad for a Wet Dress Rehearsal (WDR).That WDR is being conducted to mitigate any issues before the interplanetary launch window opens. Atlas V has a three-week period to launch Solar Orbiter while Earth and Venus are properly aligned to carry out the mission plan.Once the WDR is accomplished and the rocket is returned to the VIF from the pad, crews will mount Solar Orbiter atop the rocket. The spacecraft is undergoing final preparations at the Astrotech payload processing facility in Titusville, which is wh ere the satellite will be fueled and then encapsulated in the rocket's four-meter-diameter payload fairing.Launch of Solar Orbiter is scheduled for Feb. 5.The spacecraft's a highly elliptical orbit will periodically swing by Venus and Earth to receive gravity-assists in order to refine the orbit around the sun and change the viewing angle to see the poles.The first encounter with the sun occurs this June.Scientists on the mission want to know how the heliosphere is generated and how it is accelerated, what is driving the solar wind -- the stream of electrically charged particles that the sun emits in all directions of space -- and what causes the sun to vary in intensity over the 11-yr solar cycle. Solar Orbiter will pass just 26 million miles from the sun.Solar Orbiter is an international cooperative mission between European Space Agency (ESA) and NASA. ESA's Engineering & Test Center (ESTEC) in The Netherlands is managing the development effort, the spacecraft was developed by Airbus and the European Space Operations Center (ESOC) in Germany will operate Solar Orbiter after launch.ULA is conducting the launch under contract to NASA's Launch Services Program.

Photo credits: NASA/Ben SmegelskyThe 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.Solar Orbiter is an international cooperative mission between ESA (European Space Agency) and NASA. The mission aims to study the Sun, its outer atmosphere and solar wind. The spacecraft will provide the first images of the Sun's poles. NASA's Launch Services Program based at Kennedy Space Center in Florida is managing the launch. Liftoff is scheduled for Feb. 5, 2020.

Цитировать NASA's Launch Services Program @NASA_LSP 4 ч. назадВ ответ @ulalaunch @LitsasNASA requires a WDR for missions with limited launch opportunities such as those to planets and the Sun. WDRs allow us to test the rocket early in an effort to mitigate issues that could result in a missed opportunity for launch.
ЦитироватьAtlas 5 for Solar Orbiter launch returns to assembly building for inspectionsJanuary 22, 2020 | Stephen Clark The United Launch Alliance Atlas 5 rocket for the Solar Orbiter mission rolled out to Cape Canaveral's Complex 41 launch pad Tuesday, Jan. 21, for a planned wet dress rehearsal Wednesday. Credit: United Launch AllianceUnited Launch Alliance moved its next Atlas 5 rocket off its Florida launch pad Wednesday for inspections after a cooling duct unexpectedly disconnected before a planned countdown rehearsal to prepare for liftoff next month with the joint U.S.-European Solar Orbiter mission.The roll back to the Vertical Integration Facility at Cape Canaveral's Complex 41 launch pad could delay Solar Orbiter's liftoff, which was scheduled for Feb. 5 during a two-hour window opening at 11:27 p.m. EST (0427 GMT on Feb. 6).Officials are not sure why the umbilical duct on the launch pad disconnected Wednesday, but brisk winds on Florida's Space Coast could be the culprit. Tory Bruno, ULA's CEO, tweeted that engineers want to be sure the problem was not caused by something else.ULA planned to fill the Atlas 5 rocket with cryogenic liquid hydrogen and liquid oxygen propellants Wednesday during a simulated countdown, also called a Wet Dress Rehearsal, or WDR. The launcher's first stage was loaded with RP-1 kerosene fuel Tuesday after rolling out of the vertical assembly building for the quarter-mile trip to pad 41."During preparations for Solar Orbiter Wet Dress Rehearsal, a duct which provides cooling to the avionics, became detached from the Centaur upper stage," ULA said on Twitter. "To be prudent, we will return the vehicle to the Vertical Integration Facility to conduct inspections."The Atlas 5 launch team does not perform a WDR before every launch, but NASA requires ULA to perform a fueling demonstration before missions lofting interplanetary probes with limited launch opportunities."NASA requires a WDR for missions with limited launch opportunities such as those to planets and the sun," NASA said. "WDRs allow us to test the rocket early in an effort to mitigate issues that could result in a missed opportunity for launch."Instead of performing the Wet Dress Rehearsal on Wednesday and returning the rocket to the VIF on Thursday for attachment of the Solar Orbiter spacecraft, ULA will have to inspect the disconnected duct, determine why it became displaced, and then reattach it before returning the Atlas 5 and its mobile launch platform to pad 41 for another run at the Wet Dress Rehearsal.Ground teams planned to transfer the European-built Solar Orbiter spacecraft from its processing facility to the VIF at pad 41 this weekend, but that schedule is in jeopardy with the delay in the completion of the Wet Dress Rehearsal.The Atlas 5 rocket and its mobile launch platform are seen beginning the journey back to ULA's Vertical Integration Facility on Wednesday, Jan. 22, for inspections. Credit: Spaceflight NowThe Atlas 5 rocket assigned to launch the Solar Orbiter mission was stacked inside the Vertical Integration Facility over the last few weeks. The Atlas 5 will fly in the rarely-used "411" configuration with a 4-meter fairing, a single strap-on solid rocket boosters and a Centaur upper stage powered by a single RL10 engine.Ten scientific instruments aboard Solar Orbiter will measure the sun's output and take the first detailed images of the sun's poles. NASA is paying for the launch of the European Space Agency science probe — built in Britain by Airbus Defense and Space — as part of an international collaboration on the nearly $1.7 billion Solar Orbiter mission.Scientists will use data from Solar Orbiter, in tandem with measurements from NASA's Parker Solar Probe, to better understand what causes the solar wind, and what drives the 11-year solar cycle.The Solar Orbiter mission's launch period opens Feb. 5 and extends through Feb. 23. The mission has 19 daily launch opportunities to depart Earth in February and intercept Venus in December 2020, the first of numerous flybys to use the planet's gravity to reshape Solar Orbiter's trajectory around the sun, eventually reaching an orbit inside that of Mercury.A backup launch opportunity is available in October 2020, but that would require Solar Orbiter to use a different sequence of planetary flybys, delaying the start of the mission's regular science operations phase from August 2021 to September 2023, officials said.The gravity assist flybys with Venus will also ratchet up the tilt angle of the spacecraft's orbit around the sun, enabling Solar Orbiter to take the first images of the sun's polar regions.
