NASA Orders Three More Orion Spacecraft From Lockheed Martin

Lockheed Martin is the prime contractor to NASA for the Orion program and has completed two Orion vehicles – EFT-1 which flew in 2014, and Artemis I, which is weeks away from its launch to the Moon – and is actively building vehicles for the Artemis II-V missions.

«Lockheed Martin is honored to partner with NASA to deliver Orion spacecraft for NASA’s Artemis missions. This order includes spacecraft, mission planning and support, and takes us into the 2030s», said Lisa Callahan, vice president and general manager for Commercial Civil Space, Lockheed Martin. «We’re on the eve of a historic launch kicking off the Artemis era and this contract shows NASA is making long-term plans toward living and working on the Moon, while also having a forward focus on getting humans to Mars».

This order marks the second three missions under the agency’s Orion Production and Operations Contract (OPOC), an Indefinite-Delivery, Indefinite-Quantity (IDIQ) contract for up to 12 vehicles. A breakout of these orders includes:

  • 2019: NASA initiates OPOC IDIQ and orders three Orion spacecraft for Artemis
  • missions III-V.
  • 2022: NASA orders three additional Orion spacecraft missions for Artemis VI-VIII for $1.99 billion.
  • In the future: NASA can order an additional six Orion missions.

Under OPOC, Lockheed Martin and NASA have reduced the costs on Orion by 50% per vehicle on Artemis III through Artemis V, compared to vehicles built during the design and development phase. The vehicles built for Artemis VI, VII and VIII will see an additional 30% cost reduction.

«We’re achieving substantial cost savings from Artemis III through Artemis VIII by extensive structure and system reuse and incorporating advanced digital design and manufacturing processes», said Tonya Ladwig, Orion vice president and program manager at Lockheed Martin Space. «The Artemis II vehicle will reuse select avionics from the Artemis I crew module, and that reuse will continue to dramatically increase to where the Artemis III pressure vessel capsule will be entirely refurbished for the Artemis VI mission».

Additionally, the company will drive out cost from these production vehicles through material and component bulk buys from suppliers and an accelerated mission cadence.

With the Artemis I Orion spacecraft currently on top of the Space Launch System rocket, there are two other Orion vehicles undergoing assembly at NASA’s Kennedy Space Center in Florida, Artemis II and III. Work is well under way on the Artemis IV craft including welding the pressure vessel together at NASA’s Michoud Assembly Facility near New Orleans and the heat shield at Lockheed Martin’s facility near Denver, and work has already begun on the Artemis V vehicle.

The final satellite in the SBIRS program series, GEO-6 joins the U.S. Space Force’s constellation of missile warning satellites equipped with powerful scanning and staring infrared surveillance sensors.

«The need for Overhead Persistent Infrared systems has never been more critical», said Michael Corriea, vice president of Lockheed Martin Space’s Overhead Persistent Infrared (OPIR) Mission Area. «At Lockheed Martin, we are making advancements to keep pace with evolving needs based on emerging threats in our military customers’ environment, helping pave the way for the future».

The GEO-6 satellite is a stepping stone toward the resilient missile warning to be provided by SBIRS’ successor, the Next Generation OPIR GEO System (NGG). Like SBIRS GEO-5 and GEO-6, NGG will be based on Lockheed Martin’s modernized LM 2100 Combat Bus, which provides additional capabilities such as cyber hardening, resiliency features, enhanced spacecraft power, and improved propulsion and electronics.

The SBIRS GEO-6 satellite is responding to the U.S. Space Force’s commands as planned. Signal acquisition was confirmed 3 hours and 43 minutes after the satellite’s 6:29 a.m. EDT lift off aboard a United Launch Alliance (ULA) Atlas V rocket. The satellite is now orbiting under its own propulsion following separation from the rocket. The onboard sensors collect data that allow the U.S. military to detect missile launches, support ballistic missile defense, expand technical intelligence gathering and bolstering situational awareness on the battlefield.

 

A Step Toward More Resiliency

The OPIR mission has become more critical as ballistic missile technology has proliferated around the world with over 1,000 missile launches tracked annually. Lockheed Martin recognizes that modernized technology is needed to augment the current missile warning architecture and improve resiliency against attacks.

«SBIRS GEO-6 fortifies the current missile warning architecture, and it also signifies that we are on our way to achieving even greater technological capacity and expanded coverage with NGG», Corriea said.

Lockheed Martin is proud to be part of the SBIRS team led by Space Systems Command’s Space Sensing Directorate at Los Angeles Air Force Base. Lockheed Martin Space, Sunnyvale, California, is the SBIRS prime contractor, with Northrop Grumman of Azusa, California, as the payload supplier.

BOLE booster

Northrop Grumman Corporation and NASA successfully conducted a full-scale static fire of NASA’s Space Launch System (SLS) rocket motor, known as Flight Support Booster-2. The five-segment solid rocket booster is the world’s largest solid rocket motor and will provide more than 75 percent of the SLS rocket’s initial thrust during launch.

Over 300 measurement channels assessed the 154-foot-long/50-meter-long solid rocket booster as it fired for just over two minutes producing upwards of 3.6 million pounds of thrust. Today’s test evaluates new materials and demonstrates a new motor ignition system and an electronic thrust vector control system that steers the motors to provide data for the development of the next-generation Booster Obsolescence and Life Extension (BOLE) boosters.

Northrop Grumman was awarded a contract to develop the BOLE booster in December 2021. The award also included follow-on production and flight sets for Artemis IV through Artemis VIII, and a BOLE booster set for Artemis IX.

«Continuous product improvements and obsolescence mitigation helps NASA achieve its long-term mission to utilize SLS for its Artemis program», said Wendy Williams, vice president, propulsion systems, Northrop Grumman. «This opportunity for early learning on next-generation systems will help us develop an enhanced booster that is ready to support the greater payload demands of the SLS rocket through 2031».

Booster segments for Artemis II, the first crewed Artemis mission, and Artemis III, the mission that will land the first woman and first person of color on the lunar surface, are complete. Artemis IV segments are currently being cast with propellant and the first BOLE booster composite segment case to be used for development testing completed winding in October.

Northrop Grumman has supplied rocket propulsion for NASA’s Apollo and Space Shuttle Programs and developed the five-segment SLS solid rocket booster based on the flight-proven design of the space shuttle boosters. Designed with an additional segment and upgraded technology and materials, each of the twin solid rocket boosters generates 25 percent more thrust than its predecessor boosters to aid the SLS rocket’s ability to deliver greater mass and volume to space with greater departure energy than any existing launch vehicle.

Along with the twin solid rocket boosters, Northrop Grumman also produces the abort motor and attitude control motor for NASA’s Orion spacecraft’s Launch Abort System that increases astronaut safety on pad and during ascent. The company further supports the Artemis program providing the Habitation and Logistics Outpost module for NASA’s lunar Gateway and internally developing a Lunar Terrain Vehicle that supports human and robotic exploration of the moon and beyond.

«Northrop Grumman’s GEM 63XL is the longest monolithic, single-cast solid rocket booster ever produced», said Wendy Williams, vice president, propulsion systems, Northrop Grumman. «Built on decades of expertise, our newest GEM motors provide customers with an affordable, repeatable and reliable product they can trust to boost their most important missions».

The company began development of the fourth- and fifth-generation GEM strap-on boosters in 2015 under a cooperative agreement with ULA to provide additional lift capability for the Atlas V and Vulcan launch vehicles. Leveraging decades of flight-proven heritage while utilizing advanced technologies, teams successfully developed and tested innovative solutions to meet ULA design objectives. Both boosters use common materials and processes to offer a low cost, high-reliability, repeatable product.

The GEM 63 solid rocket booster flew its inaugural flight on ULA’s NROL-101 mission in November 2020. To date, 13 GEM 63 boosters have supported four Atlas V launches, with nine more scheduled to support three more Atlas V launches in 2022. Each booster contributes 371,500 pounds/168,510 kg of additional maximum thrust to the launch vehicle, and up to five boosters can support an Atlas V launch.

The GEM 63XL booster is scheduled to support ULA’s Vulcan Centaur rocket later this year in the extended length variation’s first flight.

Gravitational waves

Airbus has been awarded a contract from the European Space Agency (ESA) to further develop the implementation of LISA (Laser Interferometer Space Antenna), one of the most ambitious science missions ESA has planned to date. With Phase B1 now underway, the detailed mission design and final technology development activities for the gravitational wave observatory are due to be completed by 2024, with launch planned for the late 2030s.

Laser Interferometer Space Antenna (LISA)
Airbus to further develop LISA gravitational wave observatory mission

Gravitational waves were first postulated by Albert Einstein. They are distortions in space-time, created when for example supermassive black holes – billions of times heavier than our sun – merge. These events are so powerful that the resulting gravitational waves can be measured by sensitive instruments from billions of light years away.

To measure these waves, LISA consists of three spacecraft that form an equilateral triangle deep in space, 2.5 million kilometres/1,553,428 miles apart from each other. Gravitational waves stretch and compress space-time, causing the tiniest changes in distance between the LISA probes (less than the diameter of an atom). Any movements of test masses that free-fall inside the three spacecraft when a gravitational wave passes can be detected by the spacecrafts’ sensitive instruments. LISA will do this by using lasers that continuously transmit back and forth between the satellites using interferometry, measuring the distance between each of the test masses.

Some of the key technologies required for LISA were successfully tested in space with the LISA Pathfinder (LPF) mission developed and built by Airbus as prime. The mission results showed that LPF operated even more precisely than required for LISA. LPF was launched on 3rd December 2015 and ended in July 2017.

Gravitational waves are a new research method that uses gravity instead of light to measure dynamic processes in the universe. The study of gravitational waves offers enormous potential for discovering parts of the universe that are invisible in other ways. LISA will significantly expand our knowledge of the beginning, evolution, and structure of our universe. Gravitational waves have been detected by ground-based observatories in recent years – by experiments such as Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European Virgo observatory – but these facilities are limited in size and sensitivity, meaning that they are only able to detect high-frequency gravitational waves from particular sources (such as merging stellar-mass black holes and neutron stars).

Space Solar Power

In honor of Earth Day, the Air Force Research Laboratory, or AFRL, is highlighting its efforts toward harnessing the Sun’s energy, converting it to Radio Frequency, or RF, and beaming it to the Earth providing a green power source for the U.S. and allied forces.

SSPIDR
Day focus – Beaming solar power from satellite array

Key technologies need to be developed to make such a challenging process a reality.

In response to this challenge, AFRL formed the Space Solar Power Incremental Demonstrations and Research, or SSPIDR, project to develop the critical technologies needed for such a system. These technologies include further improving solar cell efficiencies; solar to RF conversion and beam forming; reducing large temperature fluctuations on spacecraft components; and deployable structure concept designs.

«A major objective of SSPIDR is to break the one-meter-squared aperture threshold for solar power capture and conversion, and beam that energy to the ground», said James Winter, AFRL principal engineer and SSPIDR project manager. «AFRL will do this with Arachne, SSPIDR’s keystone flight experiment that is anticipated to launch in early 2025».

Other demonstrations of the target technologies include the Space Power INcremental DepLoyables Experiment, or SPINDLE, – a deployable structures experiment still undergoing trade studies, and the Space Power InfRared Regulation and Analysis of Lifetime, or SPIRRAL, experiment – a thermal experiment exploring the concept of using variable emissivity materials to reduce the large temperature swings experienced by spacecraft components on orbit. SPIRRAL is anticipated to launch in 2023 for a test campaign onboard the International Space Station.

«The technologies demonstrated by Arachne, SPINDLE and SPIRRAL will pave the way for an integrated large scale, space-based solar power system capable of collecting solar energy, converting it to RF and beaming it to a receiving station on the ground for conversion to clean, usable power», Winter said.

Colonel Eric Felt, the director of the AFRL Space Vehicles Directorate, considers SSPIDR one of his most important programs.

«An operational system like SSPIDR would provide power ‘on demand’ anywhere on the globe regardless of weather or latitude, day or night and without vulnerable logistics lines», Felt said.

The value of space solar power has been internationally recognized as a foundational capability in need of development.

«This technology will enable expanded space capabilities and give us military advantage, as well as provide economic growth and commerce with more sustainable energy sources». Felt said. «We are excited about the possibilities that the conversion of space solar power energy brings to our national defense and the humanitarian and green energy benefits it will offer to the world».
