(AUG 14) PETERSON SPACE FORCE BASE, Colo. -- The 75th Intelligence, Surveillance and Reconnaissance Squadron was activated as a unit under Space Delta 7 - Intelligence, Surveillance and Reconnaissance, during a ceremony Aug. 11, 2023, at Peterson Space Force Base, Colorado.

During the activation ceremony, U.S. Space Force Col. Brett Swigert, DEL 7 commander, presented Lt. Col. Travis Anderson with the ceremonial guidon, representing the first assignment of authority from the delta commander to the 75th ISRS's first commander.

"Today is a monumental time in the history of our service," said Anderson. "The idea of this unit began four years ago on paper and has probably been in the minds of several U.S. Air Force intelligence officers even longer."

The 75th ISRS has three primary mission focuses: target analysis, target development and target engagement. Their goal is to prepare and present intelligence packages about a target and the system it is a part of. That could include information about a satellite, a ground station, or the signal in between.

"The 75th ISRS conducts advanced analysis on adversary space force and counterspace force threats along with their associated architectures," said Anderson. "Space forces are space capabilities used by a country to facilitate their joint warfighting. Counterspace forces, also called space attack forces, are space capabilities designed to deny the United States the ability to use our satellite systems during conflict."

According to Master Sgt. Desiree Cabrera, 75th ISRS operations superintendent, the new squadron is the first and only targeting unit dedicated to supporting the U.S. Space Force and its missions.

"Over the past year, the senior enlisted leader, Senior Master Sgt. Cristy Duncan, along with the first assigned members of the targeting team, led Space Delta 7's Operating Location-Bravo using an innovative approach to build the foundation and organizational structure of today's 75th ISRS." said Cabrera. "Not only are we standing up the sole targeting squadron in the U.S. Space Force, we are changing the way targeting is done across the joint community when it comes to space and electromagnetic warfare."

Since its launch from Vandenberg AFB, Calif. 23 years ago, NASA's Terra spacecraft has provided a treasure trove of interesting Earth images. On August 3 the craft's MODIS instrument recorded this view of a phytoplankton bloom (blue area) in the Barents Sea adjacent to Norway and Russia. The milky-blue color that dominates this bloom points to the likely presence of coccolithophores, a type of microscopic plankton that tend to bloom in the Barents Sea from July through September.

UCLA-led study of NASA's DART mission determines that the strategy presents previously unanticipated risks

(AUG 4) In September 2022, NASA deliberately slammed a spacecraft into the asteroid Dimorphos to knock it slightly off course. More

(JUL 26) On July 26, NASA's OSIRIS-REx spacecraft fired its engines for about 63 seconds to slightly thrust itself onto a course closer to Earth.

Preliminary tracking data indicates OSIRIS-REx changed its velocity, which includes speed and direction, by 1.3 miles, or 2 kilometers, per hour. It's a tiny but critical shift; without course adjustments like this one the spacecraft would not get close enough to Earth on Sept. 24 to drop off its sample of asteroid Bennu.

The spacecraft is currently 24 million miles, or 38.6 million kilometers, away, traveling at about 22,000 miles, or about 35,000 kilometers, per hour toward Earth.

Over the next few days, engineers will use data collected before and after today's engine burn, including Doppler radar data, to make sure the maneuver executed as planned and the spacecraft is on the right path.

Today's trajectory correction maneuver is the final adjustment needed to set up OSIRIS-REx to return to Earth on Sept. 24. Two more maneuvers, on Sept. 10 and 17, will target the precise point in Earth's atmosphere where the spacecraft's sample-return capsule must enter to land on target at the Department of Defense's Utah Test and Training Range near Salt Lake City.

(JUL 21) On the evening of July 19th, SpaceX launched a Falcon 9 rocket from Vandenberg Space Force Base in California. Sky watchers from southern California to Arizona witnessed a magnificent exhaust plume. At the San Francisco Volcanic Field north of Flagstaff, photographer Jeremy Perez saw something extra:

"After the rocket passed overhead, a red fluorescent glow expanded southward and crossed over the Milky Way," says Perez. "It was visible for almost 20 minutes."

The red glow is a sign that the rocket punched a hole in the ionosphere--something SpaceX and others have been doing for years. One famous example occured on August 25, 2017, when a Falcon 9 rocket carrying Taiwan's FORMOSAT-5 satellite created a hole four times bigger than the state of California. On June 19, 2022, another Falcon 9 punched a hole over the east coast of the USA, sparking a display of red lights from New York to the Carolinas that many observers mistook for aurora borealis.

"This is a well studied phenomenon when rockets are burning their engines 200 to 300 km above Earth's surface," explains space physicist Jeff Baumgardner of Boston University. "The red glow appears when exhaust gasses from the rocket's 2nd stage cause the ionosphere to recombine quickly."

Rocket engines spray water (H2O) and carbon dioxide (CO2) into the ionosphere, quenching local ionization by as much as 70%. A complicated series of charge exchange reactions between oxygen ions (O+) and molecules from the rocket exhaust produce photons at a wavelength of 6300 Å--the same color as red auroras.

"I reviewed footage from the July 19th launch," says Baumgardner. "It shows the second stage engine burning at 286 km near the ionosphere's F-region peak for that time of day. So, it is quite possible that an ionospheric 'hole' was made."

Once rare, ionospheric "punch holes" are increasingly common with record numbers of rocket launches led by SpaceX sending Starlink satellites to low-Earth orbit. Ham radio operators may notice them when shortwave signals fail to skip over the horizon, shooting through holes instead of bouncing back to Earth. Sudden GPS errors can also result from the anomalies. These effects may be troublesome, but they are shortlived; re-ionization occurs as soon as the sun comes up again.

Scientists have found evidence of a universal background of gravitational waves, or ripples in the fabric of space-time.

(JUN 28) PASADENA, Calif. - The motion of black holes and other massive objects through space can create ripples in the fabric of the universe, called gravitational waves. On June 28 scientists announced the first evidence of a background of long-wavelength gravitational waves that fills the cosmos. These waves are thought to have been created over eons by supermassive black holes, up to billions of times the mass of our Sun, circling each other before they merge. Detecting the gravitational wave background is analogous to hearing the hum of a large group of people talking at a party, without distinguishing any particular voice.

The background ripples detected by NANOGrav could help scientists better understand how gravitational waves are created and what happens to them as they propagate through the universe. They could also be used to study supermassive black hole mergers, events that can last for millions of years. Scientists think these mergers happen in most galaxies and influence their evolution.

The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) presented the evidence in a series of papers published in the Astrophysical Journal Letters. NANOGrav is a National Science Foundation-funded Physics Frontiers Center of more than 190 scientists from the United States and Canada, including scientists at NASA's Jet Propulsion Laboratory in Southern California and other NASA centers. The collaboration has spent more than 15 years collecting high-precision data from ground-based radio telescopes, looking for these gravitational waves.

The discovery complements the first-ever detection of gravitational waves in 2015 by LIGO, the Laser Interferometer Gravitational Observatory. Those signals, at a much shorter wavelength than the new discovery, were from black holes about 30 times the mass of our Sun.

NASA is contributing to the ESA (European Space Agency)-led Laser Interferometer Space Antenna mission, a future space-based observatory that will detect gravitational waves that are in a wavelength range between those detected by NANOGrav and LIGO.

(JUN 19) HUNTSVILLE, Ala. - Aerojet Rocketdyne has successfully completed the qualification static fire test of the eSR-19, the advanced large solid rocket motor that will power the Missile Defense Agency's (MDA) next generation Medium Range Ballistic Missile (MRBM) target used to test our nation's missile defense systems.

The successful qualification test, conducted by Air Force Research Laboratory (AFRL) and Aerojet Rocketdyne personnel at AFRL's test facility at Edwards Air Force Base, California, paves the way for delivery of flight test motors later this year.

The eSR-19 is a redesigned version of the SR-19 that currently serves as the second stage of the nation's Minuteman III strategic missiles. Featuring a lighter, filament-wound composite case and other performance-enhancing improvements, the eSR-19 will provide the propulsion for both stages of MDA's air-launched, medium-range target vehicle, developed by Aerojet Rocketdyne subsidiary Coleman Aerospace.

The motor was designed and fabricated in Aerojet Rocketdyne facilities in Huntsville, Alabama, and cast and cured in Camden, Arkansas. The eSR-19 motors are later integrated into the target systems by the Coleman Aerospace team in Orlando, Florida.

This recent qualification test was the latest achievement in the evolution of Aerojet Rocketdyne's legacy Large Solid Rocket Motor (LSRM) capabilities, which have included investments in a talented workforce and new modern LSRM facilities.

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.

(FEB 25) Weather permitting, observers in Southwest and beyond will see a celestial close encounter the evening of March 1 when Venus and Jupiter will be separated by half a degree. Their apparent proximity will be an illusion, however. The planets will lie in the same direction as seen from Earth, but be in different parts of the solar system. To see the display, look in the west about 30 minutes after sunset.

(FEB 10) BARKSDALE AIR FORCE BASE, La. -- A team of Air Force Global Strike Command Airmen launched an unarmed Minuteman III intercontinental ballistic missile equipped with a test reentry vehicle at 11:01 p.m. Pacific Time Feb. 9 from Vandenberg Space Force Base, California. More

(FEB 3) A Falcon 9 rocket was successfully launched January 31 from Vandenberg Space Force Base, Calif. The vehicle lifted off from south base at 08:15 PST and flew southward as it carried 49 Starlink Internet satellites and an Italian rideshare payload into orbit.

A few minutes after launch, Bob Brown sent the following report to the webmaster:

"Just had to send you a note about the launch from Vandenberg that took place 5 minutes ago. In all the years that I've observed launches from my street between Santa Barbara and Goleta, this was easily the clearest,most vibrant view of the rocket (through binocs) that I've ever seen. I credit that to the crisp, clear winter air and side lighting from an early morning sun. The shock waves haven't hit here just yet but should occur any moment. Just WOW!!"

(JAN 12) Preliminary analysis of data from the Start Me Up mission has begun to shed light on the outcome of the January 9th flight and next steps to follow. More

(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.
