"Rocket to the Moon: What Is the Exploration Upper Stage?

NASA’s Space Launch System (SLS) rocket delivers propulsion in stages to send NASA’s Orion spacecraft and heavy cargo to the Moon for the Artemis lunar missions. At liftoff, the core stage and twin solid rocket boosters fire to propel the rocket off the launch pad send it into orbit. Once in orbit, the upper stage provides the in-space propulsion to set the spacecraft on a precise trajectory. While the rocket’s core stage design will remain the same for each of the Artemis missions, the rocket’s upper stage is selected to meet various mission requirements and goals. For the first three Artemis missions, including the mission that will land the first woman and the next man on the Moon by 2024, SLS will utilize an interim cryogenic propulsion stage with one RL10 engine to send Orion to the Moon. Later missions with the evolved SLS Block 1B rocket configuration will use an exploration upper stage with larger fuel tanks and four RL10 engines to send a crewed Orion and large cargos to the Moon.

NASA is working to land the first woman and next man on the Moon by 2024. SLS and Orion, along with the Gateway in orbit around Moon, are NASA’s backbone for deep space exploration. SLS is the only rocket that can send Orion, astronauts and supplies to the Moon in a single mission."

The Interim Cryogenic Propulsion Stage (ICPS) has been lowered into place on the SLS rocket!

Once in orbit, the ICPS & its single RL10 engine will provide nearly 25,000 pounds of thrust to send Orion on a precise trajectory to the Moon

things currently keeping my flesh vessel going: the ICPS convention location is officially santa rosa, california, and it’s from august 3rd to 5th....i can attend this conference..........

Under Pressure

Structural Tests Underway for Top of World's Most Powerful Rocket

Testing is underway at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on the agency’s new Space Launch System, the world’s most powerful rocket. SLS and NASA’s Orion spacecraft will enable deep-space missions, beginning a new era of exploration beyond Earth’s orbit.

Engineers at Marshall have stacked four qualification articles of the upper part of SLS into a 65-foot-tall test stand using more than 3,000 bolts to hold the hardware together. Tests are currently underway to ensure the rocket hardware can withstand the pressures of launch and flight. 

The integrated tests consists of:

1. Launch Vehicle Adapter

2. Frangible Joint Assembly

3. Interim Cryogenic Propulsion Stage

4. Orion Stage Adapter

Engineers are using 28 load pistons to push, pull and twist the rocket hardware, subjecting it to loads up to 40 percent greater than that expected during flight. More than 100 miles of cables are transmitting measurements across 1,900 data channels.

The Launch Vehicle Stage Adapter, LVSA, connects the SLS core stage and the Interim Cryogenic Propulsion Stage, ICPS. The LVSA test hardware is 26.5 feet tall, with a bottom diameter of 27.5 feet and a top diameter of 16.8 feet. The frangible joint, located between the LVSA and ICPS, is used to separate the two pieces of hardware during flight, allowing the ICPS to provide the thrust to send Orion onto its mission.

The ICPS is a liquid oxygen/liquid hydrogen-based system that will give Orion the big, in-space push needed to fly beyond the moon before it returns to Earth on the first flight of SLS in 2018. For this test series, the fuel tanks are filled with nonflammable liquid nitrogen and pressurized with gaseous nitrogen to simulate flight conditions. The nitrogen is chilled to the same temperature as the oxygen and hydrogen under launch conditions.

The Orion Stage Adapter connects the Orion spacecraft to the ICPS. It is 4.8 feet tall, with a 16.8-foot bottom diameter and 18-foot top diameter.

The first integrated flight for SLS and Orion will allow NASA to use the lunar vicinity as a proving ground to test systems farther from Earth, and demonstrate Orion can get to a stable orbit in the area of space near the moon in order to support sending humans to deep space, including the Journey to Mars.

ICPS readies for transport to launch site.

The first Interim Cryogenic Propulsion Stage for NASA’s Space Launch System rocket is preparing for its barge voyage to Florida. The ICPS is the second stage of the massive booster and will propel Orion towards the moon on Exploration Mission-1.  Once in Florida, the ICPS will undergo checkout and testing at ULA’s Delta Operations and Control Center at SLC-37. NASA’s Ground System Development Office will then transport the stage to the Vehicle Assembly Building at Kennedy Space Center for final prelaunch processing. Only the Block 1 variant of the SLS will use the ICPS, with the Block 2 version using the Exploration Upper Stage. ICPS is a modified Delta IV upper stage similar to what ULA is currently using.
