Georges Lemaître: Preparing for the ATV's 5th and Final Flight...

The ATV-5 'Georges Lemaître' is placed on its Ariane 5 launch vehicle in the Final Assembly Building at Europe’s Spaceport in Kourou, French Guiana...on July 11, 2014.

ATV-5: Loaded and Locked (Press Release)

ESA’s fifth Automated Transfer Vehicle is now scheduled for launch to the International Space Station at 23:44 GMT on 29 July (01:44 CEST 30 July) on an Ariane 5 rocket from Europe’s Spaceport in Kourou, French Guiana.

ATV-5 will deliver more than six tonnes of cargo to the Station, again breaking the record for the heaviest spacecraft launched on Ariane. Everything has been loaded and the ferry is now sealed until it reaches the orbital outpost.

ESA astronaut Alexander Gerst will be the first to open the hatch of ATV Georges Lemaître in space when he takes responsibility for the cargo as ‘loadmaster’.

Alexander will manage the unloading of 6.6 tonnes of experiments, spare parts, clothing, food, fuel, air, oxygen and water for the six astronauts living in the weightless laboratory.

Cargo for Science

The star of the manifest is ESA’s Electromagnetic Levitator, which will study metals suspended in weightlessness as it heats them to 1600°C and then allows them to cool. The 400 kg unit was carefully loaded into ATV-5 in Kourou before the vessel’s propulsion module was attached.

ATV’s two main sections were then mated, leaving access to the cargo hold only through the forward hatch used by the astronauts. A special lift allowed technicians to enter the hold from above through this hatch, weeks before final closing time. Fifty-seven bags were loaded this way, including last-minute spare parts such as a pump to help recycle water on the Station.

Since the Station does not have a washing machine, cargo ships often bring fresh changes of clothes for the crews. This time, ATV-5 is also carrying high-tech ESA Spacetex t-shirts that promise to stay fresher for longer.

Also aboard is the Haptics-1 touchy-feely joystick, which will investigate how people feel tactile feedback in space, preparing for remote robotic operations from orbit.

Cargo for Life

Georges Lemaître is carrying many more experiments from Station partners in Japan and USA, from Zebrafish muscles to body-motion analysers, and even the mundane equipment any self-respecting laboratory stocks such as gloves, wipes, blood tubes and sample kits.

ATV-5 will also deliver more drinking water than ever before, as well as replenishing the astronauts’ food store.

Alexander and his crewmates will spend many hours unloading the cargo, but there is no rush – Georges Lemaître will stay attached to the Station for around six months.

NASA's Orion spacecraft crew module has been stacked on the service module inside the Operations and Checkout Building at Kennedy Space Center -- renamed on July 21, 2014 as the Neil Armstrong Operations and Checkout Building in honor of the legendary astronaut and first man to set foot on the moon, Neil Armstrong.

The Operations and Checkout Building was built in 1964. The facility has played a vital role in NASA’s spaceflight history. The high bay was used during the Apollo program to process and test the command, service and lunar modules. The facility is being used today to process and assemble NASA’s Orion spacecraft as the agency prepares to embark on the next giant leap in space exploration, sending astronauts to an asteroid and Mars.

RS-25, No. 0525: A Space Shuttle Main Engine Starts A New Life...

NASA Begins Engine Test Project for Space Launch System Rocket (Press Release)

Engineers have taken a crucial step in preparing to test parts of NASA's Space Launch System (SLS) rocket that will send humans to new destinations in the solar system. They installed on Thursday an RS-25 engine on the A-1 Test Stand at the agency's Stennis Space Center near Bay St. Louis, Mississippi.

The Stennis team will perform developmental and flight certification testing of the RS-25 engine, a modified version of the space shuttle main engine that powered missions into space from 1981 to 2011. The SLS's core stage will be powered by a configuration of four RS-25 engines, like the one recently installed on the A-1 stand.

"This test series is a major milestone because it will be our first opportunity to operate the engine with a new controller and to test propellant inlet conditions for SLS that are different than the space shuttle," said Steve Wofford, SLS Liquid Engines Element manager. "This testing will confirm the RS-25 will be successful at powering SLS."

Early tests on the engine will collect data on the performance of its new advanced engine controller and other modifications. The controller regulates valves that direct the flow of propellant to the engine, which determines the amount of thrust generated during an engine test, known as a hotfire test. In flight, propellant flow and engine thrust determine the speed and trajectory of a spacecraft. The controller also regulates the engine startup sequence, which is especially important on an engine as sophisticated as the RS-25. Likewise, the controller determines the engine shutdown sequence, ensuring it will proceed properly under both normal and emergency conditions.

"Installation of RS-25 engine No. 0525 signals the launch of another major rocket engine test project for human space exploration on the A-1 Test Stand," said Gary Benton, RS-25 rocket engine test project manager at Stennis.

The SLS is designed to carry astronauts in NASA's Orion spacecraft deeper into space than ever before, to destinations including an asteroid and Mars. NASA is using existing and in-development hardware and infrastructure, including the RS-25 engine, to the maximum extent possible to enable NASA to begin deep space missions sooner.

Testing of engine No. 0525 begins in the coming weeks on a test stand originally built in the 1960s for Apollo-era engines that helped launch the lunar missions. The stand has since been used for several major testing projects, and NASA spent almost a year modifying the structure to accommodate the RS-25 engine.

The SLS Program is managed at NASA's Marshall Space Flight Center in Huntsville, Alabama. Aerojet Rocketdyne of Sacramento, California, is on contract with NASA to adapt the RS-25 engines for SLS missions.

As tomorrow marks the 45-year anniversary since Apollo 11's launch to the Moon, just thought I'd share these two great illustrations of NASA's next manned rocket, the Space Launch System (SLS). The SLS looks very much like its predecessor, the Saturn V, but the core stage of the actual vehicle will be covered in orange spray-on foam (the same type of thermal insulation that enshrouded the space shuttle's external tank since STS-3 in 1982) and not be completely white like the workhorse rocket of the Apollo program. Despite this, it will be a sight to see once this 321-foot-tall behemoth (and eventually its 400-foot-tall variant) rolls from Kennedy Space Center's Vehicle Assembly Building to Launch Complex 39B in 2017. Can't wait.
