Engineers have now assembled the first major piece of core stage hardware for NASA’s Space Launch System (SLS) rocket which is designed to herald a new era of exploration beyond low-Earth orbit, launching crew and cargo on deep space exploration missions to the Moon, Mars and beyond.

It now is ready to be joined with other hardware for Exploration Mission-1, the first integrated flight of SLS and the Orion spacecraft, NASA said in a statement on Wednesday.

The 212-foot-tall core stage, referred to as the “backbone” of the rocket by NASA, will contain the SLS rocket’s four RS-25 rocket engines, propellant tanks, flight computers and much more.

Though the smallest part of the core stage, the forward skirt will serve two critical roles. It will connect the upper part of the rocket to the core stage and house many of the flight computers, or avionics.

“Completion of the core stage forward skirt is a major step in NASA’s progress to the launch pad,” said Deborah Bagdigian, lead manager for the forward skirt at the agency’s Marshall Space Flight Center in Huntsville, Alabama.

“We’re putting into practice the steps and processes needed to assemble the largest rocket stage ever built. With the forward skirt, we are improving and refining how we’ll conduct final assembly of the rest of the rocket,” Bagdigian said.

As part of forward skirt testing, the flight computers came to life for the first time as NASA engineers tested critical avionic systems that will control the rocket’s flight.

Located throughout the core stage, the avionics are the rocket’s “brains,” controlling navigation and communication during launch and flight.

It is critical that each of the avionics units is installed correctly, work as expected and communicate with each other and other components, including the Orion spacecraft and ground support systems.

“It was amazing to see the computers come to life for the first time,” said Lisa Espy, lead test engineer for SLS core stage avionics.

“These are the computers that will control the rocket as it soars off the pad for Exploration Mission-1,” Espy added. (IANS)

SpaceX Plans To Send NASA Astronauts To Space in Q2 This Year

As part of the test on Sunday, SpaceX configured Crew Dragon to trigger a launch escape about 1.5 minutes after liftoff

After NASA and SpaceX successfully completed a launch escape demonstration of the company’s Crew Dragon spacecraft and Falcon 9 rocket, Elon Musk said that his aerospace company aims to send NASA astronauts to space between April and June this year.

This was the final major flight test of the spacecraft before it begins carrying astronauts to the International Space Station (ISS) under NASA’s Commercial Crew Programme, the US space agency said in a statement on Sunday.

With this test now complete, the next big flight of the Crew Dragon will have people on board: NASA astronauts Bob Behnken and Doug Hurley.

“We’re highly confident that the hardware will be ready in Q1, most likely at the end of February but no later than March. And we think it appears probable that the first crewed launch would occur in the second quarter,” said Musk after the successful uncrewed test of its Crew Dragon capsule’s in-flight launch escape capabilities.

Musk said that if all goes well, the first crewed flight on the Crew Dragon could take place in the second quarter of this year.

“This critical flight test puts us on the cusp of returning the capability to launch astronauts in American spacecraft on American rockets from American soil,” said NASA Administrator Jim Bridenstine. “We are thrilled with the progress NASA’s Commercial Crew Programme is making and look forward to the next milestone for Crew Dragon.”

As part of the test on Sunday, SpaceX configured Crew Dragon to trigger a launch escape about 1.5 minutes after liftoff. All major functions were executed, including separation, engine firings, parachute deployment and landing. Crew Dragon splashed down at 10:38 am just off the Florida coast in the Atlantic Ocean.

“As far as we can tell thus far, it’s a picture perfect mission. It went as well as one can possibly expect,” said Musk. “This is a reflection of the dedication and hard work of the SpaceX and NASA teams to achieve this goal. Obviously, I’m super fired up. This is great.”

Prior to the flight test, teams completed launch day procedures for the first crewed flight test, from suit-up to launch pad operations. The joint teams now will begin the full data reviews that need to be completed prior to NASA astronauts flying the system during SpaceX’s Demo-2 mission. “The past few days have been an incredible experience for us,” said astronaut Doug Hurley.

“Today, we watched the demonstration of a system that we hope to never use, but can save lives if we ever do. It took a lot of work between NASA and SpaceX to get to this point, and we can’t wait to take a ride to the space station soon,” he said in the NASA statement. (IANS)
