Northrop Grumman Enhances Design of Next-Generation Overhead Persistent Infrared Polar Satellites

Digital technology keeps the development of polar-orbit missile-warning satellites on an accelerated pace

(MAR 14) REDONDO BEACH, Calif. - Northrop Grumman Corporation (NYSE: NOC) has refined the design of Next-Generation Overhead Persistent Infrared (OPIR) Polar (NGP) satellites by leveraging digital technology called Highly Immersive Virtual Environment (HIVE). The satellites are being built by Northrop Grumman for the U.S. Space Force's Space Systems Command (SSC).

Northrop Grumman's HIVE technology allows engineers to design, build, maintain and service satellites in virtual reality before any hardware is manufactured or procured. Real-time modeling, simulation, visualization and human interaction reduce technical costs and risks early in the development phases.

"With digital engineering, we can move through the design, testing and manufacturing phases quickly and with agility, saving money and significantly reducing development timelines for large systems," said Carol Erikson, vice president, systems engineering and digital transformation, Northrop Grumman.

As part of the Next-Generation Overhead Persistent Infrared System (Next-Gen OPIR), two NGP satellites will provide precise, timely sensor coverage over the northern hemisphere to help deter and defend against ballistic and hypersonic missiles. NGP combines Northrop Grumman's proven experience in missile warning and defense with a commitment to delivering NGP at an accelerated pace.

During a recent HIVE demonstration, conducted at the company's facility in Redondo Beach, California, Northrop Grumman engineers donned virtual-reality goggles and motion-capture suits to simulate the integration and assembly of the satellites' key components. Engineers validated the NGP design and will continue to use digital technology in the next stages of the satellites' development.

In March 2022, Northrop Grumman announced its partnership with Ball Aerospace to design and develop the two NGP satellite infrared payloads in the first phase of a $1.89 billion SSC contract.

Space Systems Command Launches EWS Cubesat Technical Demonstration

(JAN 3) EL SEGUNDO, Calif. - Space Systems Command successfully launched its Electro-Optical/Infrared (EO/IR) Weather Systems (EWS) cubesat technical demonstration this morning onboard the SpaceX Transporter-6 mission at 9:56 a.m. (Eastern, 6:56 a.m. Pacific) from Cape Canaveral Space Force Station, Florida.

This one-year EWS cubesat technical demonstration will prove out emerging space-based EO/IR radiometric imaging technology, using a smaller sensor to provide timely weather imagery data from low Earth orbit (LEO).

"The EWS cubesat technical demonstration effort represents SSC's continued commitment to working with non-traditional partners to broaden the competitive industrial base. If successful, this will provide an innovative option to deliver Space-Based Environmental Monitoring data to the warfighter at an operationally relevant speed," said Lt. Col. Joe Maguadog, EWS Materiel Leader and Program Manager. "This demonstration will inform our transition toward a more affordable, scalable, and resilient EO/IR weather constellation."

In February 2002, the EWS program competitively selected two vendors to develop and launch two separate sensor prototypes. Orion Space Solutions, a non-traditional government contractor, delivered the cubesat for this demonstration. General Atomics Electromagnetic Systems Group will deliver the second prototype by 2025.

This launch satisfies the FY20 National Defense Authorization Act (NDAA) Congressional mandate to launch a weather EO/IR pathfinder prototype by FY23. The program expects the first transmittal of data early in the new year.

Exoplanet Filters

Exoplanet instrument filters

Light shines through several filters on NASA's Roman Space Telescope Coronagraph Instrument's Color Filter Assembly. Each filter blocks all but a specific wavelength of light and many appear dark because they are only transparent to infrared light. The instrument will block the light from distant stars so that scientists can better see exoplanets around the stars. It will demonstrate technologies needed to eventually study potentially habitable planets with future missions. The Roman Coronagraph Instrument was designed and is being built at NASA's Jet Propulsion Laboratory. Image: Credit: NASA/JPL-Caltech

NASA Awards Launch Services Contract for Sentinel-6B Mission

(DEC 20) NASA has selected Space Exploration Technologies (SpaceX) of Hawthorne, California, to provide launch services for the Sentinel-6B mission. Sentinel-6B will continue the long-term global sea level data record begun in 1992 by Topex/Poseidon followed by Jason 1, 2, 3, and Sentinel-6 Michael Freilich. The mission is a partnership between NASA, the National Oceanic and Atmospheric Administration, ESA (European Space Agency), and the European Organization for the Exploitation of Meteorological Satellites.

This is a firm fixed price contract with a value of approximately $94 million, which includes launch services and other mission related costs. The Sentinel-6B mission currently is targeted to launch November 2025, on a SpaceX Falcon 9 rocket from Space Launch Complex 4E at Vandenberg Space Force Base in California.

Sentinel-6B will use a radar altimeter to bounce signals off the ocean surface and deliver continuity of ocean topography measurements. The mission also will collect high-resolution vertical profiles of temperature, using the Global Navigation Satellite System Radio-Occultation sounding technique, to assess temperature changes in Earth�s atmosphere and improve weather prediction models.

NASA�s Launch Services Program at the Kennedy Space Center in Florida is responsible for program management of the SpaceX launch services. The Sentinel-6B project office is located at NASA�s Jet Propulsion Laboratory in Pasadena, California.

(DEC 9) The SWOT satellite, or the Surface Water and Ocean Topography mission, is now encapsulated in its payload fairing in preparation for launch. Technicians at the SpaceX processing facility at Vandenberg Space Force Base in California completed the operation and will soon mate the fairing to the top of a Falcon 9 rocket. The fairing protects the satellite from aerodynamic pressure and heating during ascent. After the rocket escapes Earth�s atmosphere, the fairing separates into two halves, which are jettisoned back to Earth.

Once in orbit, SWOT will measure the height of water in freshwater bodies and the ocean on more than 90% of Earth�s surface. This information will provide insights into how the ocean influences climate change; how a warming world affects lakes, rivers, and reservoirs; and how communities can better prepare for disasters, such as floods.

SWOT is a collaborative effort by NASA and France�s Centre National d��tudes Spatiales (CNES) with contributions from the Canadian Space Agency (CSA) and UK Space Agency.

Launch is targeted for Dec. 15, 2022, at 3:46 a.m. PST from Space Launch Complex 4E at Vandenberg Space Force Base.

Rocket Lab Selected for TROPICS Mission

(NOV 23) NASA has selected Rocket Lab USA Inc. of Long Beach, California, to provide the launch service for the agency�s Time-Resolved Observations of Precipitation Structure and Storm Intensity with a Constellation of Smallsats (TROPICS) mission, as part of the agency's Venture-class Acquisition of Dedicated and Rideshare (VADR) launch services contract.

The TROPICS mission consists of four CubeSats intended for two low-Earth orbital planes and is part of NASA�s Earth System Science Pathfinder Program. Rocket Lab will launch the TROPICS satellites into their operational orbits during a 60-day period (first insertion to final insertion). These two dedicated Federal Aviation Administration (FAA) licensed launches, each on an Electron Rocket are targeted to launch no earlier than May 1, 2023, enabling NASA to provide observations during the 2023 Atlantic hurricane season, which begins June 1.

The TROPICS constellation targets the formation and evolution of tropical cyclones, including hurricanes and will provide rapidly updating observations of storm intensity, as well as the horizontal and vertical structures of temperature and humidity within the storms and in their surrounding environment. These data will help scientists better understand the processes that effect these high-impact storms, ultimately leading to improved modeling and prediction.

Building on NASA's previous procurement efforts to foster development of new launch vehicles for NASA payloads, VADR provides FAA-licensed commercial launch services for payloads that can tolerate higher risk. By using a lower level of mission assurance, and commercial best practices for launching rockets, these highly flexible contracts help broaden access to space through lower launch costs.

(OCT 30) A Falcon 9 rocket carrying 53 Starlink satellites was successfully launched from Vandenberg SFB Thursday evening, October 27, at 6:14 p.m. PDT. Liftoff took place at Vandenberg SFB sunset, making the sky relatively bright in western California and northwest Mexico. Despite this, the rocket's exhaust plume and contrail were more visible than expected.

I observed the launch from a location about 101 statute miles (163 kilometers) east-southeast of the launch pad. During the early part of the first stage burn, I looked at the Falcon 9 using the naked eye and it appeared to be heading towards me. Using 10X tripod-mounted binoculars, I could clearly see the rocket's shape, details in the flame, staging, and the jettisoned first stage and nose cone clamshells. I was able to follow the second stage burn through the binoculars until the rocket was low in the southeast and passed behind a tree. Nine minutes after liftoff I heard a sonic boom followed a minute later by a distant, faint rumble.

The launch was seen over a wide area that included South San Jose, Sacramento, Bakersfield, and the Coachella Valley, California; Las Vegas, Nevada; Saint George, Utah; Phoenix and Tucson, Arizona; and El Paso, Texas. Observers further east the best view of the launch because the Sun was further below the horizon at liftoff and the rocket's exhaust plume had a darker sky for a background.

JPSS-2 Stacked Atop LOFTID Spacecraft

JPSS-2 spacecraft payload stacking

(OCT 13) Preparations continue for the launch of the National Oceanic and Atmospheric Administration�s (NOAA) Joint Polar Satellite System-2 (JPSS-2) satellite. On Tuesday, Oct. 4, JPSS-2 was attached to its payload adapter inside the Astrotech Space Operations facility at Vandenberg Space Force Base in California. On Wednesday, Oct. 5, technicians and engineers completed the mate process using a crane to lift JPSS-2 and attach it to the top of the stack containing the re-entry vehicle for the Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID, technology demonstration.

To prepare LOFTID for stacking, technicians mated the re-entry vehicle payload adapter interface ring to LOFTID inside Building 836 at Vandenberg. Then the team mated the payload adapter separation system inside the re-entry vehicle payload adapter canister. Finally, technicians lifted the payload adapter canister over the re-entry vehicle to complete the stack. The LOFTID stack was moved to Astrotech to complete mating operations with JPSS-2.

Next up, the assembly will be encapsulated in a protective payload fairing. After encapsulation, the team will transport the encapsulated spacecraft to Space Launch Complex-3 where a crane will hoist it up for attachment to the second stage of the United Launch Alliance Atlas V 401 rocket.

JPSS-2 and LOFTID together measure approximately 27 feet tall. Launch is targeted for Nov.1 from Vandenberg. NASA�s Launch Services Program, based at the agency�s Kennedy Space Center in Florida, is managing the launch.

Engineers Solve Data Glitch on NASA's Voyager 1

(AUG 30) PASADENA, Calif. - Engineers have repaired an issue affecting data from NASA's Voyager 1 spacecraft. Earlier this year, the probe's attitude articulation and control system (AACS), which keeps Voyager 1's antenna pointed at Earth, began sending garbled information about its health and activities to mission controllers, despite operating normally. The rest of the probe also appeared healthy as it continued to gather and return science data.

The team has since located the source of the garbled information: The AACS had started sending the telemetry data through an onboard computer known to have stopped working years ago, and the computer corrupted the information.

Suzanne Dodd, Voyager's project manager, said that when they suspected this was the issue, they opted to try a low-risk solution: commanding the AACS to resume sending the data to the right computer.

Engineers don't yet know why the AACS started routing telemetry data to the incorrect computer, but it likely received a faulty command generated by another onboard computer. If that's the case, it would indicate there is an issue somewhere else on the spacecraft. The team will continue to search for that underlying issue, but they don't think it is a threat to the long-term health of Voyager 1.

"We're happy to have the telemetry back," said Dodd. "We'll do a full memory readout of the AACS and look at everything it's been doing. That will help us try to diagnose the problem that caused the telemetry issue in the first place. So we're cautiously optimistic, but we still have more investigating to do."

Voyager 1 and Voyager 2 have been exploring our solar system for 45 years. Both probes are now in interstellar space, the region outside the heliopause, or the bubble of energetic particles and magnetic fields from the Sun.

Northwestern Rocket to Image Supernova Remnant

Project will study how the explosion spreads �star stuff' throughout the galaxy

(AUG 11) EVANSTON, Ill. - A Northwestern University astrophysics team is aiming for the stars - well, a dead star, that is.

On Aug. 21, the NASA-funded team will launch its "Micro-X" rocket from White Sands Missile Range in southern New Mexico. The rocket will spend 15 minutes in space � just enough time to snap a quick image of supernova remnant Cassiopeia A, a star in the Cassiopeia constellation that exploded approximately 11,000 light-years away from Earth. Then, the rocket will parachute back to Earth, landing in the desert � about 45 miles from the launchpad � where the Northwestern team will recover its payload.

Short for "high-resolution microcalorimeter X-ray imaging rocket," the Micro-X rocket will carry a superconductor-based X-ray imaging spectrometer that is capable of measuring the energy of each incoming X-ray from astronomical sources with unprecedented accuracy.

"The supernova remnant is so hot that most of the light it emits is not in the visible range," said Northwestern's Enectali Figueroa-Feliciano, who leads the project. "We have to use X-ray imaging, which isn't possible from Earth because our atmosphere absorbs X-rays. That's why we have to go into space. It's like if you jumped into the air, snapped a photo just as your head peeked above the atmosphere and then landed back down."

X-Bow Successfully Launches "Bolt" Rocket

Bolt is the first in X-Bow's new suite of sub-orbital and orbital capable launch vehicles

(JUL 26) WHITE SANDS, N.M. -- X-Bow Systems (X-Bow), today confirmed the successful first launch of its Bolt Rocket at White Sands Missile Range. Bolt is the first vehicle in X-Bow's new suite of modular boost rockets. The mission, named XL-2, carried a Payload Test Vehicle for the Department of Energy's Los Alamos National Laboratory (LANL). With the success of this launch, the X-Bow team continues to usher new technologies, capabilities and competition into the solid rocket motor (SRM) Industrial Base.

X-Bow's team will now examine the XL-2 mission data, inspect the recovered hardware and move on to test its additively manufactured solid propellant technology on its second mission, sponsored by the U.S. Army Space and Missile Defense Command (SMDC) and the Department of Defense Innovation Unit (DIU). Multiple further launches of increasing size and capabilities in support of, and under contract with additional customers are scheduled through 2024 and beyond. X-Bow also continues to offer its Bolt 'Orbital Vehicle' to the U.S. Space Force on the OSP-4 contract.

The Bolt launch follows last month's successful static fire of the 32" diameter Ballesta Solid Rocket Motor. The Ballesta motor and the Bolt rocket were both built and assembled in tactical field conditions with minimal tools and handling gear. At full production, X-Bow will launch monthly, or more frequently, from various sub-orbital ranges across the US and its territories.

Northrop Grumman Tests Abort Motor

(MAR 31) PROMONTORY, Utah - Northrop Grumman Corporation (NYSE: NOC) and Lockheed Martin successfully performed the final full-scale ground test of the abort motor for NASA's Orion spacecraft Launch Abort System (LAS) at Northrop Grumman's Promontory test facility. The 17-foot-tall abort motor is one of three motors comprising the LAS that sits atop the Orion spacecraft aboard NASA's Space Launch System (SLS) rocket and is designed to increase astronaut safety on the pad and through initial ascent.

Approximately 250 measurement channels assessed the abort motor as the four exhaust nozzles pointing skyward produced nearly 400,000 pounds of thrust over its two-second firing time. Today's test concludes the verification of a new insulation formulation and completes qualification testing for the Orion's LAS.

"This impressive, high-impulse motor burns three times faster than a typical motor of this size, and if needed, the reverse-flow nozzles pull the crew capsule away from the launch vehicle and to safety," said Wendy Williams, vice president, propulsion systems, Northrop Grumman. "Together, the three solid rocket motors of the LAS equip the SLS with the highest human-rated thrust and acceleration safety system possible."

The first active LAS system will be integrated into the Orion spacecraft for Artemis II, the first crewed flight of SLS.

STSS Satellites Complete Mission

(MAR 15) REDONDO BEACH, Calif. - Built by Northrop Grumman Corporation (NYSE: NOC) in support of the Missile Defense Agency, two demonstration Space Tracking and Surveillance System (STSS) satellites successfully completed their missions and have been retired. Their achievements pave the way for future operational missile warning and tracking systems that will defend the nation.

"Launched in 2009 and expected to operate for four years, these demonstration satellites outlived their design life threshold three times over," said Sarah Willoughby, vice president, overhead persistent infrared and geospatial systems, Northrop Grumman. "Now we are applying what we learned from STSS for future systems to keep America and its allies safe."

The STSS experimental spacecraft proved their ability to detect and track short-, medium-, intermediate- and intercontinental-range missiles from boost phase to midcourse, then communicate target-quality track data to command and control systems for interception.

The satellites used sensors to detect and track ballistic missiles for interception. They tracked targets; helped discriminate real threats, guide interceptors to targets, and assess interceptor hits; collected data on launches, on-orbit satellites, satellite re-entries and other space-based missions; and played a critical role in one of MDA's integrated Ballistic Missile Defense System flight test.

Firm Selected for Rocket to
Return First Mars Samples

(FEB 7) WASHINGTON, D.C. - NASA has awarded a contract to Lockheed Martin Space of Littleton, Colorado, to build the Mars Ascent Vehicle (MAV), a small, lightweight rocket to launch rock, sediment, and atmospheric samples from the surface of the Red Planet.

Set to become the first rocket fired off another planet, the MAV is a crucial part of a campaign to retrieve samples collected by NASA's Perseverance rover and deliver them to Earth for advanced study. NASA's Sample Retrieval Lander, another important part of the campaign, would carry the MAV to Mars' surface, landing near or in Jezero Crater to gather the samples cached by Perseverance. The samples would be returned to the lander, which would serve as the launch platform for the MAV. With the sample container secured, the MAV would then launch.

Once it reaches Mars orbit, the container would be captured by an ESA (European Space Agency) Earth Return Orbiter spacecraft outfitted with NASA's Capture, Containment, and Return System payload. The spacecraft would bring the samples to Earth safely and securely in the early- to mid-2030s.

Returning a sample is complicated, and MAV faces some complex development challenges. It must be robust enough to withstand the harsh Mars environment and adaptable enough to work with multiple spacecraft. It also must be small enough to fit inside the Sample Retrieval Lander. The Sample Retrieval Lander is planned for launch no earlier than 2026 from NASA's Kennedy Space Center in Florida.

Lockheed Martin Space will provide multiple MAV test units and a flight unit. Work under the contract includes designing, developing, testing, and evaluating the integrated MAV system, and designing and developing of the rocket's ground support equipment.

The cost-plus-fixed-fee Mars Ascent Vehicle Integrated System (MAVIS) contract has a potential value of $194 million. The performance period begins no later than Feb. 25 and will extend six years.

This strategic NASA and ESA partnership would be the first mission to return samples from another planet and the first launch from the surface of another planet. The samples collected by Perseverance during its exploration of an ancient river delta are thought to present the best opportunity to reveal the early evolution of Mars, including the potential for life.

NASA Awards Virgin Orbit Launch Services Contract

(JAN 27) LONG BEACH, CALIFORNIA - Virgin Orbit (Nasdaq: VORB) announced today its selection by NASA's Launch Services Program to provide launch services for the agency's Venture-Class Acquisition of Dedicated Rideshare (VADR) missions. The fixed-price indefinite-delivery/indefinite-quantity contract will leverage commercial satellite launch practices, and together with the flexibility afforded by Virgin Orbit's LauncherOne system enables more efficient launch timelines, mission-tailored orbits, and competitive costs.

"This contract award is a great step forward for commercial space," said Dan Hart, CEO of Virgin Orbit. "The VADR contract vehicle now provides a platform for NASA to more easily contract for flights on our LauncherOne service. That means it will be easier than ever for us to work with NASA to provide targeted and economic access to space, maximizing the science gains from their small satellite missions and enabling ever greater technological innovation."

Virgin Orbit has already launched thirteen satellites to space for NASA through programs like the Venture Class Launch Services program and the CubeSat Launch Initiative. In a similar spirit the VADR acquisition will build on that foundation. The contract has a five-year ordering period with a maximum total value of $300 million and will be managed by the Launch Services Program at the agency's Kennedy Space Center in Florida.

NASA's selection of Virgin Orbit as a VADR launch provider comes fresh off the company's third successful launch in under twelve months, wherein it brought its unblemished count of successfully deployed satellites to 26. Having already proven out the LauncherOne system, reached new orbital inclinations never before possible from the West Coast, and even launched through inclement weather, Virgin Orbit is now scaling up its flight rate to accommodate the high demand seen from commercial customers, the national security community, the international community and, through programs like VADR, the US civil space community.

ICEYE US Wins NRO Contract

(JAN 20) Irvine, CALIFORNIA - ICEYE US, a subsidiary of ICEYE, the global leader in persistent Earth monitoring with radar satellite imaging, announced today that it has received a contract from the National Reconnaissance Office (NRO). This contract enables ICEYE US to participate in the NRO's evaluation of commercial remote sensing companies operating synthetic aperture radar (SAR) satellites.

With a focus on modeling and simulation, ICEYE US will support NRO's detailed assessment of imaging modes, image quality, geolocation accuracy and coverage among other important technical parameters. The contract represents a critical step in NRO's plan to leverage next generation commercial radar providers to deliver innovative, resilient, and responsive satellite imagery for intelligence, defense, and humanitarian efforts.

ICEYE US builds and operates U.S.-licensed SAR spacecraft from its facility in Irvine, California. The company successfully launched its first-ever satellite earlier this month with SpaceX and Exolaunch. ICEYE's satellites are small, each weighing about 220 pounds, but provide customers with detailed images and measurements of activities on the surface of the Earth. Such satellites can be continually improved on ground and in space with new technologies and in response to specific customer requirements.

At any given time, most of the Earth is covered in clouds or darkness. Unlike traditional Earth observation satellites, ICEYE's small radar imaging satellites can form high-resolution images of areas of the Earth in daylight, at night, and through cloud cover. In other words, they can "see" any part of the Earth multiple times a day. ICEYE's satellites can collect images over wide areas and even more detailed images over smaller points of interest. This provides customers with persistent coverage of fast breaking events on the ground in all weather conditions.

Virgin Orbit Launch Successful

(JAN 13) MOJAVE, CALIFORNIA - Virgin Orbit (Nasdaq: VORB), the responsive launch and space solutions company, confirmed it successfully deployed into orbit all 7 customer satellites onboard its LauncherOne rocket during today's Above the Clouds mission.

Virgin Orbit's 747 carrier aircraft Cosmic Girl took off from Mojave Air and Space Port this afternoon at approximately 1:39 PM PST/09:39 PM UTC and flew to a launch site over the Pacific Ocean, about 50 miles south of the Channel Islands. After a smooth release from the aircraft, the LauncherOne rocket ignited and propelled itself towards space, ultimately deploying its payload into a precise target orbit approximately 500km above the Earth's surface at 45 degrees inclination. This is the first time that anyone has reached this orbit from the West Coast.

The launch was the company's third successful flight, occurring less than one year from its first mission. Virgin Orbit has now successfully delivered commercial, government, international, and national security satellites to space, including new Above the Clouds customer Spire Global, Inc. (NYSE: SPIR), and first ever repeat customers: the U.S. Department of Defense Space Test Program and Polish company SatRevolution. This launch was awarded to Virgin Orbit through its subsidiary VOX Space by the DoD's Defense Innovation Unit (DIU) as part of the DoD Space Test Program's (STP) Rapid Agile Launch (RALI) Initiative.

The satellites launched on the company's latest mission include experiments in space-based communications, space debris detection, and in-space navigation and propulsion, as well as satellites that will serve the global agricultural sector. The launch brings the total number of satellites launched by Virgin Orbit to 26.

Because of the unique air-launch system Virgin Orbit has developed, the Above the Clouds mission was launched in an orbit never before directly accessible from the West Coast of the Americas. Rather than launching from a fixed pad on the ground, Virgin Orbit conducts its launches from under the wing of a modified 747 aircraft, and by flying the aircraft further out over the ocean, the company was able to launch on a trajectory no ground-launch rocket could have achieved. That direct injection into the target orbit saved the satellites onboard this mission months of time and kilograms of fuel they might have otherwise spent correcting their orbit from what a landlocked launch site could provide them.
