CAPE CANAVERAL AIR FORCE STATION, Fla. (ULA PR) — The United Launch Alliance (ULA) Atlas V551 rocket carrying the Lockheed Martin-built Advanced Extremely High Frequency 5 (AEHF-5) satellite for the U.S. Air Force Space and Missile Systems Center is delayed, due to an anomaly during component testing at a supplier which has created a cross-over concern. 

Additional time is needed for the team to review the component anomaly and determine if any corrective action is required to the launch vehicle. Launch of the AEHF-5 mission is now targeted for no earlier than Thursday, Aug. 8, 2019.

AEHF satellites provide highly-secure, jam-proof connectivity between U.S. national leadership and deployed military forces. Atlas V rockets successfully launched the first four AEHF satellites in 2010, 2012, 2013 and 2018.

The AEHF-5 launch will mark the 80th Atlas V mission since the inaugural launch in 2002 and the 10th in the 551 configuration. The rocket features a kerosene-fueled common core booster, five solid rocket boosters, the hydrogen-fueled Centaur upper stage and a five-meter-diameter payload fairing.

The ULA Delta IV rocket carrying the GPS III SV02 mission for the U.S. Air Force Space and Missile Systems Center is delayed, due to an anomaly during component testing at a supplier which has created a cross-over concern. 

Upon further evaluation, additional time is needed to replace and retest the component on the launch vehicle. Launch of the GPS III SV02 mission is now targeted for no earlier than Thursday, Aug. 22, 2019.

Space Development Agency
Next-Generation Space Architecture
Request for Information
SDA-SN-19-0001
July 1, 2019
[Full Solicitation]

SDA requests information from industry related to satellite bus, payload, applique, and launch concepts that can contribute to an agile, responsive next-generation space architecture. SDA has developed a notional suite of capabilities, as depicted in Figure 1, to include multiple constellations (or “layers”) addressing the eight priorities listed above. Each layer provides an integral and integrated capability to the overall architecture.

The SDA’s notional architecture is predicated on the availability of a ubiquitous data and communications transport layer and assumes the use of small, mass-produced satellites (50-500 kg) and associated payload hardware and software. The SDA is considering the use of transport layer spacecraft as substrates for other layers, allowing for the integration of appropriate payloads based on each layer’s needs.

Seven layers are proposed:

  1. Space Transport Layer: Global, persistent, low-latency data and communications proliferated “mesh” network to provide 24×7 global communications.
  2. Tracking Layer: Indications, warning, targeting, and tracking of advanced missile threats.
  3. Custody Layer: 24×7, all-weather custody of all identified time-critical targets.
  4. Deterrence Layer: Space Situational Awareness (SSA) of, and rapid access to, the cislunar volume.
  5. Navigation Layer: Alternate Positioning, Navigation and Timing (PNT) for GPS-denied environments.
  6. Battle Management Layer: Distributed, artificial intelligence-enabled Battle Management Command, Control and Communications (BMC3), to include self-tasking, self-prioritization (for collection), on-board processing, and dissemination, supporting delivery of perishable space sensor-derived data products directly to tactical users.
  7. Support Layer: Mass-producible ground command and control capabilities, user terminals, and rapid-response launch services (small- to medium-class).

Proposed concepts should align to one or more of the layers described above. SDA prefers comprehensive solutions that include open architectures (e.g., buses that support multiple payloads and software appliques, and payloads/software capable of integration aboard multiple buses) and leverage commercial capabilities, existing or planned.

SpaceX Launches 21st & Final Mission of 2018

News 18

CAPE CANAVERAL AIR FORCE STATION, Fla. (SpaceX PR) — On Sunday, December 23rd at 5:51 a.m. PST, SpaceX successfully launched the United States Air Force’s first Global Positioning System III space vehicle (SV) from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida. The satellite was deployed to its intended orbit approximately 1 hour and 56 minutes after liftoff.

The United States’ Global Positioning System delivers positioning, navigation, and timing services supporting vital U.S. and allied operations worldwide, and underpins critical financial, transportation, and agricultural infrastructure that billions of users have come to depend on daily.

The Launch Facility

The United States Air Force’s first GPS III satellite will augment the current constellation of 31 operational GPS satellites. This newest generation of GPS satellites is designed and built to deliver positioning, navigation, and timing information with three times better accuracy, and up to eight times improved anti-jamming capability. GPS is used by over four billion users and supports critical missions worldwide.

GPS is a National Security Space (NSS) mission, critical to national defense. In April 2016, SpaceX was awarded its first NSS mission, GPS III SV01. SpaceX currently has an additional four GPS III missions on contract, all of which will be launched on Falcon 9.

Space Launch Complex 40 at Cape Canaveral Air Force Station, Florida SpaceX’s SLC-40 at Cape Canaveral Air Force Station is a world-class launch site that builds on a strong heritage. The site, located at the north end of Cape Canaveral Air Force Station, was used for many years to launch Titan rockets, among the most powerful in the U.S. fleet. SpaceX took over the facility in May 2008.

The center of the complex is composed of the concrete launch pad and flame diverter system. Surrounding the pad are four lightning towers, propellant storage tanks, and the integration hangar. Before launch, Falcon 9’s stages and payload are housed inside the hangar. The payload is mated to the Falcon 9 inside SLC-40’s hangar on the transporter erector. The rocket and payload are then rolled out from the hangar to the launch pad and lifted to a vertical position.

China Sets New Record for Launches in Calendar Year

News 9

China set a new national record for the number of launches in a calendar year.

A Long March 3B booster lifted off from Xichang Satellite Launch Center with two Beidou navigation satellites bound for medium Earth orbit. It was the 23rd successful launch of the year with no failures.

To date, China has launched six boosters with 11 Beidou satellites aboard in 2018. The navigation satellite system, which is similar to the U.S. Global Positioning System and Europe’s Galileo constellation, will eventually have 35 satellites in orbit.

China’s launch total for 2018 is expected to be in the low to mid-30’s.











NOAA Issues RFP for Commercial Weather Data Pilot Program

News 0

NOAA has issued a request for proposals for the second phase of its commercial weather data pilot program.

The program’s goal is to determine whether GPS radio occultation data from commercial satellites can be used to improve weather forecasting. Radio occultation involves the change in a radio signal as it passes through Earth’s atmosphere, allowing for the measurement of physical properties there.

The firm-fixed price contracts for the second phase will run from  Aug. 27, 2018 through Sept. 30, 2019. The data collection and delivery period will run from Oct. 1, 2018 to June 30, 2019.

Companies are required to provide at least two periods of at least three consecutive months of radio occultation data during the collection period. A minimum of 500 atmospheric soundings per day are required. Data must be delivered to NOAA at least once per week.

NASA issued contracts to GeoOptics and Spire for the first phase of the pilot program in September 2016. Space News reports the program did not go very smoothly, but that NOAA officials had learned a number of key lessons from it that are being included in the second phase.

GeoOptics’ contract was terminated when the company was unable to provide data because of delays in the launch of its first satellites.

While Spire did provide data, NOAA officials said later that the quality of the data fell short of expectations. “We have gone through one contract already with the radio occultation community, and we found that the data aren’t accurate enough or comprehensive enough yet to meet our observing requirements,” Stephen Volz, NOAA assistant administrator for satellite and information services, said in January. Spire said that the data from its constellation of cubesats has improved significantly since the end of that initial round of the pilot program in April 2017.

NOAA officials have said for several months that they are working on a report analyzing the results of that first round of the Commercial Weather Data Pilot. However, NOAA spokesman John Leslie said May 7 that the report is still “nearing competition” within the agency and will be released publicly once it is completed.

Proposals for phase two are due on May 25.

Watch Masten’s Xodiac Vehicle Soar

News 9

Video Caption: Over the past five weeks, NASA and Masten teams have prepared for and conducted sub-orbital rocket flight tests of next-generation lander navigation technology through the CoOperative Blending of Autonomous Landing Technologies (COBALT) project.

The COBALT payload was integrated onto Masten’s rocket, Xodiac. The Xodiac vehicle used the Global Positioning System (GPS) for navigation during this first campaign, which was intentional to verify and refine COBALT system performance. The joint teams conducted numerous ground verification tests, made modifications in the process, practiced and refined operations’ procedures, conducted three tether tests, and have now flown two successful free flights. This successful, collaborative campaign has provided the COBALT and Xodiac teams with the valuable performance data needed to refine the systems and prepare them for the second flight test campaign this summer when the COBALT system will navigate the Xodiac rocket to a precision landing.

The technologies within COBALT provide a spacecraft with knowledge during entry, descent and landing that enables it to precisely navigate and softly land close to surface locations that have been previously too risky to target with current capabilities. The technologies will enable future exploration destinations on Mars, the moon, Europa, and other planets and moons.

The two primary navigation components within COBALT include the Langley Research Center’s Navigation Doppler Lidar, which provides ultra-precise velocity and line-of-sight range measurements, and Jet Propulsion Laboratory’s Lander Vision System, which provides navigation estimates relative to an existing surface map.

The integrated system is being flight tested onboard a Masten Space Systems suborbital rocket vehicle called Xodiac. The COBALT project is led by the Johnson Space Center, with funding provided through the Game Changing Development, Flight Opportunities program, and Advanced Exploration Systems programs.
