City of Stars
A small satellite designed to hunt for new planets beyond the solar system recently looked down
at Earth to capture an image of California's "City of Stars." The greater Los Angeles area stands
out in this view from ASTERIA, a satellite not much larger than a briefcase. The image reveals a
massive grid of illuminated city streets and freeways. A bright spot near the center of the view
marks the location of Dodger Stadium and the Port of Long Beach is visible near the lower center.
ASTERIA was developed at the Jet Propulsion Laboratory (JPL) in Pasadena, Calif., and the mission
is a collaboration with the Massachusetts Institute of Technology (MIT). Image courtesy of NASA/JPL-Caltech
Raytheon to Install GPS Receivers
(MAY 13) AURORA, Colo. -- Raytheon Company's (NYSE: RTN) GPS Next-Generation Operational Control System program, known as GPS OCX, completed final qualification testing of the system's modernized monitor station receivers, which are now ready to be installed around the world starting in August. GPS OCX is the enhanced ground control segment of a U.S. Air Force-led effort to modernize America's GPS system.
"The modernized receivers give GPS OCX the ability to receive and decrypt all GPS III military and civil signals, a critical capability the current system doesn't have," said Dave Wajsgras, president of Raytheon Intelligence, Information and Services. "Monitor station receiver installation keeps us on track for full system delivery by our June 2021 contractual deadline."
The modernized receivers will measure and monitor legacy military and civilian signals sent by the current GPS satellite constellation plus the new signals sent by the next-generation GPS III. The receivers will also feed correction models at the master control station, giving U.S. Air Force satellite controllers the information necessary to make key adjustments to maximize accuracy.

Their teamwork and combined efforts over the past few months showcase their immense dedication to the mission and why they are some of the best operators in the Air Force."
InSight Detects First Likely Marsquake
(APR 23) PASADENA, Calif. - NASA's Mars InSight lander has measured and recorded for the first time ever a likely "marsquake."
The faint seismic signal, detected by the lander's Seismic Experiment for Interior Structure (SEIS) instrument, was recorded on April 6, the lander's 128th Martian day, or sol. This is the first recorded trembling that appears to have come from inside the planet, as opposed to being caused by forces above the surface, such as wind. Scientists still are examining the data to determine the exact cause of the signal.
The new seismic event was too small to provide solid data on the Martian interior, which is one of InSight's main objectives. The Martian surface is extremely quiet, allowing SEIS, InSight's specially designed seismometer, to pick up faint rumbles. In contrast, Earth's surface is quivering constantly from seismic noise created by oceans and weather. An event of this size in Southern California would be lost among dozens of tiny crackles that occur every day.
Most people are familiar with quakes on Earth, which occur on faults created by the motion of tectonic plates. Mars and the Moon do not have tectonic plates, but they still experience quakes - in their cases, caused by a continual process of cooling and contraction that creates stress. This stress builds over time, until it is strong enough to break the crust, causing a quake.
SEIS has surpassed the team's expectations in terms of its sensitivity. The instrument was provided for InSight by the French space agency, Centre National d'Études Spatiales (CNES), while these first seismic events were identified by InSight's Marsquake Service team, led by the Swiss Federal Institute of Technology.
JPL manages InSight for NASA's Science Mission Directorate. InSight is part of NASA's Discovery Program, managed by the agency's Marshall Space Flight Center in Huntsville, Alabama. Lockheed Martin Space in Denver built the InSight spacecraft, including its cruise stage and lander, and supports spacecraft operations for the mission.

SpaceX Chosen to Launch Asteroid Mission from Vandenberg
(APR 11) NASA has selected SpaceX in Hawthorne, California, to provide launch services for the agency’s Double Asteroid Redirection Test (DART) mission, the first-ever mission to demonstrate the capability to deflect an asteroid by colliding a spacecraft with it at high speed – a technique known as a kinetic impactor.
The total cost for NASA to launch DART is approximately $69 million, which includes the launch service and other mission related costs.
The DART mission currently is targeted to launch in June 2021 on a Falcon 9 rocket from Space Launch Complex 4E at Vandenberg Air Force Base in California. By using solar electric propulsion, DART will intercept the asteroid Didymos’ small moon in October 2022, when the asteroid will be within 11 million kilometers of Earth.
NASA’s Launch Services Program at Kennedy Space Center in Florida will manage the SpaceX launch service. The DART Project office is located at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, and is managed by the Planetary Missions Program Office at Marshall Space Flight Center in Huntsville, Alabama, for NASA’s Planetary Defense Coordination Office in Washington.

Air Force and Raytheon to Modernize SPADOC
(APR 3) COLORADO SPRINGS, Colo. -- The U.S. Air Force Life Cycle Management Center and a consortium of tech firms led by Raytheon (NYSE: RTN) are modernizing and simplifying the legacy Space Defense Operations Center, a 1990s-era system that tracks and monitors space debris.
Dave Fuino, program director for Raytheon Intelligence, Information and Services, said: "Within just a few months we brought together a team, developed the technology to modernize it, got it on contract and held a series of demos to prove it worked. We went from concept to proving the solution in less than a year, which is really remarkable."
The SPADOC system reached the end of its planned service life. The U.S. Air Force is planning to replace it with modern systems that will simplify operations and provide greater space situational awareness and collision avoidance capabilities. However, the new system won't come online for several years.
"SPADOC provides critical space-tracking capabilities that we must sustain and maintain while we wait for new systems to come online," said Bob Taylor, U.S. Air Force Legacy Space Branch chief. "At the same time, it's critical that we address the obsolescence risk of an aging SPADOC system. So we came up with a really innovative, modern solution to this problem."
Raytheon and AFLCMC decided to emulate SPADOC's capabilities with modern computer hardware. The new emulated environment, SPADOC Emulation Analysis Risk Reduction, known as SPEARR, is designed to provide a more sustainable system that requires less maintenance. The new hardware will provide the same functionality as today's system, making it easy to learn and operate.
Additional benefits are significant reductions in power and cooling consumption. Most of these reductions are because all of SPADOC's capabilities are now integrated into two small server racks instead of spread over 1,000 square feet of an aging, analog computer system.
"We used proven emulation technology to help solve our challenge, significantly reducing obsolescence risk," said Taylor. "Innovations in programmatic and technical approaches drove a smarter, better and faster solution. The next step is to evaluate options for fielding SPEARR."
Missile Defense System Intercepts ICBM Target
(MAR 25) The U.S. Missile Defense Agency, in cooperation with the Joint Functional Component Command for Integrated Missile Defense, U.S. Northern Command, and elements of the U.S. Air Force Space Command’s 30th, 50th, and 460th Space Wings, conducted a successful test today against an Intercontinental Ballistic Missile (ICBM) class target. This test was the first salvo engagement of a threat-representative ICBM target by two Ground Based Interceptors (GBI), which were designated GBI-Lead, and GBI-Trail for the test. The GBI-Lead destroyed the reentry vehicle, as it was designed to do. The GBI-Trail then looked at the resulting debris and remaining objects, and, not finding any other reentry vehicles, selected the next ‘most lethal object’ it could identify, and struck that, precisely as it was designed to do.
The threat-representative ICBM target was launched from the Reagan Test Site on Kwajalein Atoll in the Republic of the Marshall Islands, over 4,000 miles away from the two GBI interceptors, which were launched from Vandenberg Air Force Base, California.
During the test, space, ground and sea-based BMDS sensors provided real-time target acquisition and tracking data to the Command, Control, Battle Management and Communication (C2BMC) system. The two GBIs were then launched and the Exo-atmospheric Kill Vehicles successfully engaged the target complex, resulting in an intercept of the target.
Initial indications show the test met requirements. Program officials will continue to evaluate system performance based upon telemetry and other data obtained during the test.
The GMD element of the ballistic missile defense system provides combatant commanders the capability to engage and destroy intermediate and long-range ballistic missile threats to protect the U.S. The mission of the Missile Defense Agency is to develop and deploy a layered ballistic missile defense system to defend the United States, its deployed forces, allies and friends from limited ballistic missile attacks of all ranges in all phases of flight.

CatSat Mission Selected by NASA
(MAR 18) An inflatable space antenna designed by University of Arizona students is one of 16 small research satellites from 10 states NASA has selected to fly as auxiliary payloads aboard space missions planned to launch in 2020, 2021 and 2022.
CatSat is a 6U CubeSat led by UA students from the Lunar and Planetary Laboratory and various departments including aerospace and mechanical engineering, astronomy, computer science, and systems and industrial engineering.
"Let's say you are flying a space probe across the solar system and you want to beam a lot of data back to the Earth," says Vishnu Reddy, the principal investigator of the mission and an associate professor at the Lunar and Planetary Laboratory. "To do that, you need a large antenna, but those are too bulky to be carried on small spacecraft such as CubeSats. To overcome the problem of getting large antennas into small spacecraft, our group of students proposed a bold mission that would test a novel inflatable antenna system in space."
CatSat is the size of a large cereal box. When fully deployed, the inflatable expands in a bubble gum fashion, forming a sphere three feet across that sticks out from one side of the box. An aluminized spot inside the inflated sphere is used as the communication antenna to beam data back to the Earth. Since Catsat will be in low Earth orbit, the data can be downloaded using a ground station located at the UA.
CatSat is mainly a technology demonstration mission to mature this inflatable concept in Earth orbit. The ultimate goal is to fly such an antenna on an interplanetary mission that Reddy wants to lead to explore small bodies in the solar system.
Inflatable antenna technology is the brain child of UA astronomy professor Christopher Walker, who is also the science principal investigator of the mission. FreeFall Aerospace, a local small business co-founded by Walker to advance inflatable antenna technology, helped the project as an industrial affiliate.
Two engineering principal investigators – Roberto Furfaro, a professor in the Department of Systems and Industrial Engineering, and Jekan Thanga, an assistant professor in the Department of Aerospace and Mechanical Engineering – are leading the student teams who are building the actual spacecraft hardware on campus.

Virgin Galactic Makes Test Flight
The Earth meets the black sky in this image taken during a Virgin Galactic flight to the edge of space on February 22. Virgin Galactic photo
(FEB 22) Mojave, California - Today, Virgin Galactic conducted its fifth powered test flight and second space flight of its commercial SpaceShipTwo, VSS Unity.
In its fifth supersonic rocket powered test flight, Virgin Galactic reached space for the second time today in the skies above Mojave CA. Spaceship VSS Unity reached its highest speed and altitude to date and, for the first time, carried a third crew member on board along with research payloads from the NASA Flight Opportunities program.
This space flight means Chief Pilot Dave Mackay and co-pilot Michael “Sooch” Masucci become commercial astronauts and the 569th and 570th humans in space. Beth Moses, Virgin Galactic’s Chief Astronaut Instructor, flew as the third crew member in a first, live evaluation of cabin dynamics. She is the 571st person to fly to space and the first woman to fly on board a commercial spaceship.
In addition to this element of envelope expansion, VSS Unity flew higher and faster than ever before, as its world record-holding hybrid rocket motor propelled the spaceship at Mach 3.04 to an apogee of 295,007ft.
The crew enjoyed extraordinary views of Earth from the black skies of space and, during several minutes of weightlessness while the pilots “feathered” the spaceship in preparation for a Mach 2.7 re-entry, Beth floated free to complete a number of cabin evaluation test points. The human validation of data previously collected via sensors, and the live testing of other physical elements of the cabin interior, are fundamental to the provision of a safe but enjoyable customer experience.
The glide back home was followed by a smooth runway landing and a rapturous reception from the crowd on the flight line, which included staff and some of Virgin Galactic’s 600 Future Astronaut customers.
The Cosmic Mystery Tour – A High-Speed Journey Through Space and Time
by Nicolas Mee (Oxford University Press; $24.95; 224 pages; available March 2019)
(FEB 15) Nicholas Mee's forthcoming book "The Cosmic Mystery Tour" is an informative and fast read. In short order the author describes the components and workings of the universe from the sub-atomic level to the universe as a whole. He also covers the evolution of our understanding of the universe, the personalities who shaped that understanding, and the intriguing topics of dark matter, extra-terrestrial life, and interstellar travel.
The entire book was interesting, but I found Mee's descriptions of the fundamental forces of the universe and sub-atomic particles especially so. I had heard references to these subjects over the decades, but really didn't know anything about them.
The author communicates in layman's terms in a clear, entertaining style. Although some of the chapters of the book could be better tied in to one another, the overall organization and flow is good. The text is supported by numerous relevant illustrations. Unfortunately, I wasn't able to fully interpret some of the graphics because the originals are in color, but were printed in black and white in my preview copy of the book.
The Cosmic Mystery tour taught me more in fewer pages than any astronomy- or space-relate book I have read thus far. It is definitely worth reading.

Atlas V Chosen for Asteroid Mission
(JAN 31) Centennial, Colo. – NASA’s Launch Services Program announced today that it selected United Launch Alliance’s (ULA’s) proven Atlas V vehicle to launch the Lucy mission, which is the first mission to Jupiter’s swarm of Trojan asteroids. This award resulted from a competitive Launch Service Task Order evaluation under the NASA Launch Services II contract.
The Lucy mission is scheduled to launch in October 2021 from Space Launch Complex-41 at Cape Canaveral Air Force Station in Florida. This mission will launch aboard an Atlas V 401 configuration rocket.
Atlas V has a strong history in launching planetary missions for NASA including Mars Science Lab; New Horizons; OSIRIS-REx, the first U.S. mission to return asteroid samples to Earth; and the Solar Dynamics Observatory to study the sun.
Jupiter's swarms of Trojan asteroids may be remnants of the primordial material that formed the outer planets, and serve as time capsules from the birth of our solar system more than 4 billion years ago. Lucy will be the first space mission to study the Trojans. The mission takes its name from the fossilized human ancestor (named “Lucy” by her discoverers) whose skeleton provided unique insight into humanity's evolution. Lucy will complete a 12-year journey to seven different asteroids.
With more than a century of combined heritage, ULA is the world’s most experienced and reliable launch service provider. ULA has successfully delivered 132 missions to orbit that provide Earth observation capabilities, enable global communications, unlock the mysteries of our solar system, and support life-saving technology.
