  • Weather Briefing: Perfect Conditions Continue

    The nation’s newest weather satellite will liftoff in ideal conditions, reported Clay Finn, launch weather officer for NOAA’s GOES-R mission. The forecast remains 100 percent chance of acceptable conditions. The launch teams continue their procedures this evening as we tick closer to liftoff at 5:42 p.m. EST.

  • The Color Change of the Rocket

    Observant watchers may have noted that the Atlas V first stage now appears white. That’s because frost formed on the outside of the rocket as its tanks filled with cryogenic oxygen. It’s the same process that causes frost to form on a glass holding a chilled liquid. Speaking of the Atlas, the oxygen tank is …

  • New Trio Arrives to Join Expedition 50 Crew

    Soyuz Approaches Station

    NASA astronaut Peggy Whitson, Oleg Novitskiy of the Russian space agency Roscosmos and Thomas Pesquet of ESA (European Space Agency) have docked to the International Space Station. After orbiting the Earth for approximately two days, their Soyuz MS-03 spacecraft docked with the space station’s Rassvet module at 4:58 p.m. EST. When hatches between the Soyuz …

  • NASA TV Coverage Begins

    NASA TV is currently airing GOES-R countdown coverage on its media channel. You can watch the coverage here on the blog or go to http://youtu.be/Fih5Wpe6ac4. The fueling of the Atlas V rocket continues this evening as the launch teams work toward liftoff at 5:42 p.m. EST from here in Florida.

  • Centaur Liquid Hydrogen Loading Begins

    Systems are pumping liquid hydrogen into the Centaur upper stage as today’s countdown proceeds toward a liftoff at 5:42 p.m. EST. The Centaur, pictured above during stacking of the Atlas V at Space Launch Complex 41, burns liquid hydrogen fuel combined with liquid oxygen during the ascent into space. The Centaur’s liquid oxygen tank is …

  • Watch New Expedition 50 Trio Dock Today

    Expedition 50 Crew Members

    Three new crew members are set to dock to the International Space Station Saturday at 5:01 p.m. EST. Live coverage of the docking and arrival will begin at 4:15 p.m. on NASA Television and the agency’s website. NASA astronaut Peggy Whitson, Oleg Novitskiy of Roscosmos and Thomas Pesquet of ESA (European Space Agency) launched in …

  • First Stage Liquid Oxygen Loading Beginning

    Liquid oxygen is flowing into the first stage of the United Launch Alliance Atlas V rocket. The engine, seen above, will combine the oxygen with refined kerosene to generate about 860,000 pounds of thrust at liftoff. This Atlas V is equipped with four solid-fueled boosters that will provide extra thrust to lift the rocket and …

  • Liquid Oxygen Loading Begins for Centaur

    Supercold liquid oxygen is flowing into the tank of the Centaur upper stage for today’s launch. The Centaur’s single RL10 engine, built by Aerojet Rocketdyne, burns a combination of liquid hydrogen and liquid oxygen to generate thrust. The Centaur will perform three burns today to place NOAA’s GOES-R satellite into a transfer orbit that will …

  • Centaur Chilldown Begins

    The transfer lines to the Centaur’s liquid oxygen tanks have begun chilling down before the supercold propellant is pumped into the tanks for launch. The tanking will begin in a few minutes. Later, the same process will be used to load liquid oxygen into the Atlas V’s first stage. After that, the liquid hydrogen for …

  • T-2 Hours and Counting

    The countdown has resumed as scheduled for the GOES-R launch today. Engineers are beginning the preparations to load cryogenic propellants into the Atlas V rocket.
