During the test, Starliner’s four launch abort engines, and several orbital maneuvering and attitude control thrusters simultaneously ignited to rapidly push the spacecraft away from the test stand. Five seconds into flight, the abort engines shut off as planned, transferring steering to the control thrusters for the next five seconds.
A pitcharound maneuver rotated the spacecraft into position for landing as it neared its peak altitude of approximately 4,500 feet. Two of three Starliner’s main parachutes deployed just under half a minute into the test, and the service module separated from the crew module a few seconds later. Although designed with three parachutes, two opening successfully is acceptable for the test parameters and crew safety. After one minute, the heat shield was released and airbags inflated, and the Starliner eased to the ground beneath its parachutes.
The demonstration took only about 95 seconds from the moment the simulated abort was initiated until the Starliner crew module touched down on the desert ground.
“Boeing’s CST-100 Starliner’s four launch abort engines and several orbital maneuvering and attitude control thrusters ignite in the company’s Pad Abort Test, pushing the spacecraft away from the test stand with a combined 160,000 pounds of thrust, from Launch Complex 32 on White Sands Missile Range in New Mexico. The test, conducted Nov. 4, 2019, was designed to verify that each of Starliner’s systems will function not only separately, but in concert, to protect astronauts by carrying them safely away from the launch pad in the unlikely event of an emergency prior to liftoff. The Pad Abort Test is Boeing’s first test flight for NASA’s Commercial Crew Program, which is working to launch astronauts on American rockets and spacecraft from American soil for the first time since 2011.” – NASA
Here is the webcast of the test. Liftoff happens at around 24:55 into the video.
Scott Manley comments on the test:
** Northrop Grumman Cygnus arrives at the ISS after traveling in space for two days since its launch on an Antares rocket on Saturday.
Unfortunately a reusable suborbital sounding rocket launched by EXOS Aerospace malfunctioned shortly after liftoff causing the vehicle to crash back to Earth minutes later. Even though today’s attempt was unsuccessful this EXOS flight was the third time a suborbital-class rocket stage has been reused for a fourth time.
The launch took place at the Spaceport America. Spaceport America which is an FAA-licensed spaceport located on 18,000 acres of State Trust Land in the Jornada del Muerto desert basin in New Mexico, directly west and adjacent to U.S. Army’s White Sands Missile Range. It lies 89 miles north of El Paso, 45 miles north of Las Cruces, and 20 miles southeast of Truth or Consequences.
** Video: Review of reusable rocket engines with Matt Richardson of Univ. of Tokyo – TMRO.tv
We’re joined by Dr Matt Richardson of U Tokyo/JAXA to talk reusable rocket engines. Matt recently graduated with a PhD in aerospace engineering where he tested ways to extend the lifetime and reduce refurbishment costs of liquid-fueled rocket engines.
… it sounds like SpaceX is serious about pursuing the consumer market from the start. When asked about price recently, Shotwell said millions of people in the U. S. pay $80 per month to get “crappy service.” She did not commit to a price, but homes, schools, community centers, etc. with crappy service would pay that for good service, not to mention those with no service. Some customers may pay around $80 per month, but the price at a given location will be a function of SpaceX capacity, the price/demand curve for Intenet service and competition from terrestrial and other satellite service providers, so prices will vary within the U. S. and globally. In nations where Starlink service is sold by partner Internet service providers, they will share in pricing decisions.
Since the marginal cost of serving a customer is near zero as long as there is sufficient capacity, we can expect lower prices in a poor, sparsely-populated region than in an affluent, densely-populated region. Dynamic pricing is also a possibility since SpaceX will have real-time demand data for every location. “Dynamic pricing of a zero marginal cost, variable-demand service” sounds like a good thesis topic. It will be interesting to see their pricing policy.
National governments will also have a say on pricing and service. While the U. S. will allow SpaceX to serve customers directly, other nations may require that they sell through Internet service providers and some — maybe Russia — may ban Starlink service altogether.
Great work by SpaceX Dragon team & Airborne! To be clear, we’ve only done 1 multi-parachute test of Mk3 design, so 9 more left to reach 10 successful tests in a row. https://t.co/Q814zVoW4S
*** Demo Starship Mk.1 coming back together. For Elon Musk’s presentation back in September, the top nosecone and lower propulsion module were stacked atop each other and each had their respective “wings” (to provide drag during reentry, not for flying) attached. After the presentation, the two parts were de-stacked and the wing sections removed. Outfitting of the Starship modules with fuel line, wiring, misc. sub-systems, etc. then proceeded. Last week the propulsion module was moved to the launch site, presumably to prepare for static engine tests. The wing sections, or canards, are now being added back to the nosecone.

*** Starship launch pad at KSC under construction:
The Starship pad at 39A is officially going vertical! You can see just how close the new launch mount is to the ramp and operational pad. Things are about to get really exciting around here. 🏗🚀 #Starship#MK2@SpaceXpic.twitter.com/KlLUqJ059S
*** Starships will eventually operate from offshore launch facilities.
That said, most Starship spaceports will probably need to be ~20 miles / 30km offshore for acceptable noise levels, especially for frequent daily flights, as would occur for point to point flights on Earth
A sampling of links to recent space policy, politics, and government (US and international) related space news and resource items that I found of interest (find previous space policy roundups here):
How can a simple report—just words on a page—lead to creation of a spacecraft? We explore how a 2019 report on the need for a dedicated, space-based telescope to find threatening near-Earth asteroids motivated NASA to pursue that very mission. We speak with Dr. Jay Melosh, planetary scientist and chair of the National Academies committee behind that report, on how it came together and how the process works behind the scenes. We also check on NASA’s budget process in Congress and news from the International Astronautical Congress in Washington, D.C.
The 70th International Astronautical Congress descended on Washington, DC this week, with 6300 delegates from around the world coming together to talk about space technology, policy and more. Jake is on site to report on the happenings, and connected with a range of people on robotic missions and human architectures.

** Tue, 10/29/2019 – Dr. Umair Siddiqui discussed the Phase Four “radio frequency plasma thruster, plasma science, Hall thrusters, LEO, comsats, mega satellite constellations and more”.
A sampling of recent articles, press releases, etc. related to student and amateur CubeSat / SmallSat projects and programs (find previous smallsat roundups here):
** NG Cygnus carries HuskySat-1, built by Univ. Washington students, to ISS.
HuskySat-1 is being developed by an interdisciplinary team at the University of Washington and will be launched into Low Earth Orbit to become the first amateur satellite from Washington state. This CubeSat will demonstrate the capabilities of new technologies being developed at the University of Washington and expand the capabilities of CubeSats as a whole. In particular, a high-thrust pulsed plasma thruster (PPT), and high-gain communications system will form the core technology suite on board the satellite. The HuskySat-1 will also be flying a newly developed Amateur Radio Linear Transponder developed by AMSAT which will contribute to the worldwide communication networks built and operated by ham radio enthusiasts.
Some of the student-built parts will still be in test mode. A custom-built thruster uses sparks to vaporize small amounts of solid sulfur as a propellant. The thruster will fire about 100 times as the satellite passes over Seattle, only enough thrust to provide a slight nudge. A high-bandwidth communications system built by former graduate student Paul Sturmer, now at Blue Origin, transmits at 24 Gigahertz, allowing the satellite to quickly send reams of data. That system will send down a test packet from space.
“Usually people buy most of the satellite and build one part of it. We built all the parts,” Northway said. “It was a pretty serious undertaking.”
On Saturday, seven small research satellites, or CubeSats, developed by students from eight universities across the nation will fly on Northrop Grumman’s Antares rocket from NASA’s Wallops Flight Facility in Wallops, Virginia, targeting a launch at 9:59 a.m. EDT.
All seven CubeSats were selected through NASA’s CubeSat Launch Initiative (CSLI) and are a part of the 25thEducational Launch of Nanosatellites (ELaNa) mission. CSLI enables the launch of CubeSat projects designed, built and operated by students, teachers and faculty, as well as NASA Centers and nonprofit organizations. ELaNa missions provide launch and deployment opportunities and ride-shares to space for CubeSats selected through CSLI. Students are heavily involved in all aspects of the mission from developing, assembling, and testing payloads to working with NASA and the launch vehicle integration teams. The ELaNa CubeSats are held to rigorous standards similar to those adhered to by the primary spacecraft.
Five of the CubeSats were developed through NASA’s Undergraduate Student Instrument Project or USIP.
The 5 USIP CubeSats flying on Antares are:
RadSat-u – Montana State University – Bozeman
Phoenix – Arizona State University – Tempe
SOCRATES (Signal of Opportunity CubeSat Ranging and Timing ExperimentS) – University of Minnesota – Minneapolis
HuskySat-1 – University of Washington – Seattle
SwampSat II – University of Florida – Gainesville
…
The additional two CubeSats flying through CSLI are:
Argus-02 – St. Louis University – Missouri
HARP (Hyper Angular Rainbow Polarimeter) – University of Maryland, Baltimore County – Baltimore and Utah State University – Logan
A constellation of South African nanosatellites will be put in orbit next year to monitor shipping to prevent the poaching of marine resources such as abalone and sharks, while they will also track fires so ground-based personnel can move livestock out of harm’s way and prevent the spread of the fire.
The technology for this constellation is being proven right now as the ZACube 2 research nanosatellite from the Cape Peninsula University of Technology (CPUT) will log its 300th day in orbit on the 23rd October 2019. ZACube 1, also known as TshepisoSat, was launched on 21st November 2013 and is still communicating with the ground station.
…
The ZACube 2 satellite is performing well in orbit and proving the technology that the university has developed,” Professor Robert van Zyl, the Director of French South African Institute of Technology (FSATI) said.
