Video: Watch RS-25 Hot Fire

Video Caption: NASA is a step closer to returning astronauts to the Moon in the next five years following this successful “hot fire” test of flight engine No. 2062 on the A-1 Test Stand at Stennis Space Center in Mississippi. This April 4, 2019 test caps more than four years of testing for the RS-25 engines that will help power the first four missions of the Space Launch System rockets. It also concludes a 51-month test series that demonstrated RS-25 engines can perform at the higher power level needed to launch the super heavy-lift SLS rocket.

NASA Achieves Rocket Engine Test Milestone Needed for Moon Missions

NASA conducts a test of RS-25 flight engine No. 2062 on April 4 on the A-1 Test Stand at Stennis Space Center near Bay St. Louis, Miss. The test marked a major milestone in NASA’s march forward to Moon missions. All 16 RS-25 engines that will help power the first four flights of NASA’s new Space Launch System rocket now have been tested. (Credits: NASA/SSC)

BAY ST. LOUIS, Miss. (NASA PR) — NASA is a step closer to returning astronauts to the Moon in the next five years following a successful engine test on Thursday at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The latest “hot fire” was the culmination of four-plus years of testing for the RS-25 engines that will send the first four Space Launch System (SLS) rockets into space.

IG: NASA Needs to Better Document Cost Savings on Services Contracts

NASA needs better methods to track its efforts to minimize costs on the more than $16 billion worth of engineering and technical services the space agency purchases annually, according to a new audit by the Inspector General (IG).

“Although NASA has a variety of mechanisms at the Headquarters and Center levels to share lessons learned, many of these are informal, dependent upon personal relationships between Centers, and not focused on sharing information on efficiencies,” the audit said.

Aviation Week has a photo gallery detailing the PGA engine developed to power the rockets that will air launched from Stratolaunch’s massive carrier aircraft. The engine’s details include:

  • fuel-rich, staged-combustion liquid oxygen and hydrogen engine capable of generating 200,000 lb. of thrust
  • three cores with single PGA engine each will power medium launch vehicle
  • fully reusable Black Ice space plane powered by three PGAs; and,
  • engine testing to begin at NASA Stennis in October.

EXECUTIVE SUMMARY

The NASA Transition Authorization Act of 2017 (P.L. 115-10) provided for an ISS Transition Report under section 303:

The Administrator, in coordination with the ISS management entity (as defined in section 2 of the National Aeronautics and Space Administration Transition Authorization Act of 2017), ISS partners, the scientific user community, and the commercial space sector, shall develop a plan to transition in a step-wise approach from the current regime that relies heavily on NASA sponsorship to a regime where NASA could be one of many customers of a low-Earth orbit non-governmental human space flight enterprise.

GAO: SLS Making Progress, Major Milestones Lie Ahead

When Congress insisted that NASA build the Space Launch System (SLS) some years back, the argument was simple: just adapt all this technology  from the space shuttle program using the workers and infrastructure that already exist to develop a new heavy-lift booster.

It all sounded deceptively simple — and deceptive it was. NASA and its contractors soon ran into a problem that affects many such projects: it’s often easier to build something from scratch than to modify systems that already exist. And there you have the problem with the SLS program in a nutshell.

Relativity Space Takes Over Test Stand at NASA Stennis

Relativity Space, a startup that is developing 3D printed launch vehicles,  has signed a 20-year agreement to use the E4 Test Complex at the NASA Stennis Space Center in Mississippi.

The 25-acre complex includes four large test cells rated for testing rocket engines and launch vehicles. The company, which has already tested engines at another Stennis test stand, said it will be investing money to build up the complex, which is currently not in use.

Relativity Space plans to use the site to complete development, qualification and acceptance testing of its Aeon rocket engine and Terran 1 launch vehicle.

“Terran 1 is designed from scratch for constellation deployment and resupply,” the company says on its website. “Its unique architecture can change and scale rapidly alongside satellite companies as they develop new capabilities.”

The company is using robotic additive manufacturing to reduce the cost of access  to orbit. It aims to be able to manufacture and launch a rocket in less than 60 days.

The two-stage booster is designed to place up to 1,250 kg (2,756 lb) into an 185 km (115 mile) orbit or 900 kg (1,984 lb) into a 500 km (311 mile) sun-synchronous orbit (SSO). The booster will also be capable of placing a 700 kg (1,543 lb) payload into a 1,200 km (746 mile) SSO.

Stratolaunch to Test Rocket Engine Technology at NASA Stennis

Stratolaunch will test rocket engine technology next year at NASA’s Stennis Space Center in Mississippi under agreements with the space agency.

Paul Allen’s company signed two agreements with NASA: an umbrella Space Act Agreement laying out the terms of cooperation, and an annex under with Stratolaunch will pay $5.1 million to the space agency to use the E1 facility at Stennis for engine tests.
