SpaceX has launched, on average, about 1.5 times per month during this year. From that perspective, the company's 16th launch of 2017 may not seem all that spectacular. After all, sending something like the Koreasat-5A commercial communications satellite to a geostationary transfer orbit is becoming old hat for the new space company. However, Monday's launch attempt is significant because it would double SpaceX's total number of launches for any given year, which was eight. Moreover, it is yet another commercial launch for SpaceX, which before 2017 had launched mostly government missions for NASA and NOAA. But this year, 11 of 16 SpaceX launches have been for private companies or foreign governments. The launch window for Monday's attempt from Kennedy Space Center opens at 3:34pm ET and will remain open until 5:58pm ET. The webcast below should begin about 15 minutes before the launch window opens. After delivering the satellite into orbit, the Falcon 9 rocket's first stage will attempt a landing on the “Of Course I Still Love You” drone ship at just under 9 minutes after launch. The satellite will be deployed about 36 minutes after liftoff. Following Monday's attempt, it is likely that SpaceX will launch two or three additional missions in 2017, which would bring the company's tally for the year to 19 missions. That total would be one shy of the company's total for 2014, 2015, and 2016 combined. Source | ||

The Mars 2020 rover will be able to show us more of the red planet than any of its predecessors ever did. NASA says the extraterrestrial vehicle will be equipped with 23 cameras, six more than Curiosity's and all a lot more capable. Seven of those "eyes" are tasked with collecting data for scientific experiments, nine are engineering cameras that will keep an eye on its surroundings for navigation and the last seven will capture the rover's descent and landing. Its main camera, however, is Mastcam-Z -- an upgraded version of Curiosity's Mastcam with a 3:1 zoom (hence, "Z") lens the original didn't have. Mastcam-Z will have the capability to take more 3D images than the first Mastcam and will give NASA scientists more info on the planet's geological features. Meanwhile, the engineering/navigation cameras will be able to capture high-resolution, 20-megapixel colored images for the first time. Previous Navcams were only able to take one-megapixel black-and-white photos, so they have to capture several and stitch them together to be able to get a clear view of the surroundings. Since these new cameras have a wider field of view as well, they don't have to waste time and processing power stitching photos together. The rover can spend that time collecting more samples and snapping more pictures instead. All those cameras will help the Mars 2020 rover achieve its goal to search for signs of past life on the red planet. Earlier this year, the agency picked three potential sites to drill, all of which have elements that could have supported life. Source | ||

A major question for SpaceX’s end of year manifest appears to be gaining some answers as the company aims to debut its Falcon Heavy rocket in the late-December time period. With one launch left off LC-39A before the pad’s final conversion for the new rocket occurs, SpaceX is understood to be targeting mid-December for the Static Fire of Falcon Heavy followed by a late-December, No Earlier Than 29 December, launch of the heavy lift rocket. The schedule for Falcon Heavy has been a fluid campaign as operations to bring SLC-40 back into operation took major priority this year following the activation and historically high use of LC-39A to ramp up and maintain SpaceX’s impressive launch cadence. This year alone has already seen 12 launches from the SpaceX-leased pad, with two more – Zuma and Falcon Heavy – planned before year end. Currently, all three cores for Falcon Heavy’s first stage are inside the Horizontal Integration Facility (HIF) outside the perimeter of LC-39A at the Kennedy Space Center, as is the second stage. Also present in the HIF is the brand new core that will launch the Zuma mission for Northrop Grumman on NET 15 November 2017 in the launch window that extends from 20:00-22:00 EST (01:00-03:00 UTC on 16 November). Once Zuma is off the ground, Falcon 9 single stick launches will largely move back to SLC-40 starting with the CRS-13 Dragon launch to the International Space Station, set for No Earlier Than (NET) 4 December. That move will free Pad-A for the final round of work needed to finish configuring the Transporter/Erector/Launcher (TEL) for Falcon Heavy. According to L2 processing notes, final TEL conversion includes cutting and welding operations and rewiring work for installation of the Falcon Heavy Tail Service Masts (TSMs) at the base of the TEL reaction frame, the removal of the Falcon 9 east/west hold down clamp inserts used for single stick Falcon 9 missions, and installation of the Falcon Heavy compression bridges to hold part of the weight between the side-mounted boosters and the center booster of the heavy-lift rocket. The Falcon 9 east/west hold down clamps have to be removed as their presence overlaps with the positioning of the Falcon Heavy side-mounted cores’ engines. Those east/west hold down clamps are currently installed on inserts to the TEL reaction frame, and once removed will create the needed exhaust holes for the side-mounted FH cores. However, the sheer weight of the Falcon Heavy necessitates the installation of compression bridges that will help hold and distribute the weight of Falcon Heavy. Source | ||

Vice President Mike Pence discussed the National Space Council with entrepreneur and inventor Elon Musk during a trip to California last month, a source familiar with the meeting says. The two powwowed at a Los Angeles hotel one evening while the vice president was in the state for a fundraising swing. The conversation focused on the council, which aims to streamline and coordinate national space policy. Pence leads the panel at President Donald Trump's direction. Musk is one of several business leaders exploring private space travel through his company, SpaceX. Musk quit two presidential advisory councils after Trump announced the United States' withdrawal from the Paris climate agreement. Musk tweeted at the time: "Am departing presidential councils. Climate change is real. Leaving Paris is not good for America or the world." On Friday, the federal government released a congressionally mandated report that found "no convincing alternative explanation" for the changing climate other than "human activities, especially emissions of greenhouse gases." SpaceX has scored a number of lucrative government contracts in recent years. The company is currently fulfilling a $1.6 billion contract with NASA to send supplies to the International Space Station. It also has an $83 million contract to send an Air Force satellite into space in 2018. Last month, it launched a spy satellite for a US intelligence agency. SpaceX referred questions to the vice president's office. Source | ||

Interesting article: According to the new research paper by Edgar Zapata, who works at Kennedy Space Center, the supply services offered by SpaceX and Orbital ATK have cost NASA two to three times less than if the space agency had continued to fly the space shuttle. For his analysis, Zapata attempted to make an "apples to apples" comparison between the commercial vehicles, through June 2017, and the space shuttle. ... For example, Zapata notes that NASA invested about $140 million in the Falcon 9 rocket to help complete its development. However, because of this investment, SpaceX has been able to launch more than 20 payloads for private customers—launches that would otherwise have almost certainly gone to overseas providers. "it is arguable that the US Treasury has already made that initial investment back and then some merely from the taxation of jobs at SpaceX and its suppliers only from non-government economic activity," the study finds. "The over $1 billion (net difference) is US economic activity that would have otherwise mostly gone abroad. This is very different from the economic benefit when NASA is a sole user of a system." Seems like the commercial crew and other programs were a pretty resounding success for the US. | ||

WASHINGTON — SpaceX said Nov. 8 that it suffered a failure of a Merlin engine during a recent test at its Texas facility, but that the incident would not delay any upcoming launches. The incident, which took place Nov. 4 and was first reported by the Washington Post, may have involved a new version of the Merlin engine being developed by SpaceX for the next upgrade of the company’s Falcon 9 launch vehicle. “SpaceX experienced an anomaly during a Qualification test set up of a Merlin engine at our rocket development facility in McGregor, Texas,” the company said in a statement to SpaceNews. No one was injured in the test, the company said, and “a thorough and fully transparent investigation” is underway, in coordination with various government agencies. SpaceX has yet to disclose specific details about the incident, which a company source said took place on a Merlin test stand that has two bays. One bay reportedly suffered damage that will take two to four weeks to repair, while the neighboring bay received only minor damage that can be repaired in days. spacenews.com Cool. | ||

In the past three years, SpaceX has made incredible progress in their program of reusability. In the practice’s first year, the young space company led by serial tech entrepreneur Elon Musk has performed three successful commercial reuses of Falcon 9 boosters in approximately eight months, and has at least two more reused flights scheduled before 2017 is out. Blue Origin, headed and funded by Jeff Bezos of Amazon fame, is perhaps most famous for its supreme confidence, best illustrated by Bezos offhandedly welcoming SpaceX “to the club” after the company first recovered the booster stage of its Falcon 9 rocket in 2015. Blue Origin began in the early 2000s as a pet project of Bezos, a long-time fan of spaceflight and proponent of developing economies in space. After more than a decade of persistent development and increasingly complex testbeds, Blue Origin began a multi-year program of test flights with its small New Shepard launch vehicle. Designed to eventually launch tourists to the veritable edge of Earth’s atmosphere in a capsule atop it, New Shepard began its test flights in 2015 and after one partial failure, has completed five successful flights in a row. The space tourism company has subtly and not-so-subtly belittled SpaceX’s accomplishments over the last several years, and has engendered a fair bit of hostility towards it as a result. Admittedly, CEO Elon Musk nurtured high expectations for the consequences of reuse, and has frequently discussed SpaceX’s ambition to reduce the cost of access to orbit by a factor of 10 to 100. However, after several reuses, it is clear that costs have decreased no more than 10-20%. What gives? Well, Musk’s many comments on magnitudes of cost reduction were clearly premised upon rapid and complete reuse of both stages of Falcon 9, best evidenced by a concept video the company released in 2011. The reality was considerably harder and Musk clearly underestimated the difficulty of second stage reuse, something he himself has admitted. COO Gwynne Shotwell was interviewed earlier this summer and discussed SpaceX’s updated approach to complete reusability, and acknowledged that second stage reuse was no longer a real priority, although the company will likely attempt second stage recovery as a validation of future technologies. Instead of pursuing the development of a completely reusable Falcon 9, SpaceX is instead pushing ahead with the development of a much larger rocket, BFR. BFR being designed to enable the sustainable colonization of space by realizing Musk’s original ambition of magnitudes-cheaper orbital launch capabilities. Meanwhile, SpaceX’s only near-term competitor interested in serious reuse has made gradual progress over the last several years, accelerating its pace of development more recently. Blue Origin’s second New Shepard vehicle, designed to serve the suborbital space tourism industry, conducted an impressive five successful launches and landings over the course of 2016 before being summarily retired. NS2’s antecedent suffered a failure while attempting its first landing and was destroyed in 2015, but Blue learned quickly from the issues of Shepard 1 and has already shipped New Shepard 3 to its suborbital launch facilities near Van Horn, Texas. While NS3 is aiming for an inaugural flight later this year, NS4 is under construction in Kent, Washington and could support Blue’s first crewed suborbital launches in 2018. More significant waves were made with an announcement in 2016 that Blue was pursuing development of a partially reusable orbital-class launch vehicle, the massive New Glenn. On paper, New Glenn is quite a bit larger than even SpaceX’s Falcon 9, and appears to likely be more capable than the company’s “world’s most powerful rocket” while completely recovering its boost stage. In a completed, manufactured, and demonstrably reliable form, New Glenn would be an extraordinarily impressive and capable launch vehicle that could undoubtedly catapult Blue Origin into position of true competition with SpaceX’s reusability efforts. However, while Blue Origin executives brag about “operational reusability” and tastelessly lampoon efforts that “decided to slap some legs on [to] see if [they] could land it”, the unmentioned company implicated in those barbs has begun to routintely and commercially reuse orbital-class boosters five times the size of Blue’s suborbital testbed, New Shepard. The only point at which Blue Origin poses a risk to SpaceX’s business can be found in a comparison of funding sources. SpaceX first successes (and failures) were funded out of Elon Musk’s own pocket, but nearly all of the funding that followed was won through competitive government contracts and rounds of private investment. To put it more simply, SpaceX is a business that must balance costs and returns, while Blue Origin is funded exclusively out of billionaire CEO Jeff Bezos’ pocket. As a result of being completely privately funded, Bezos’ deep pockets could render Blue more flexible than SpaceX when pricing launches. If Blue chooses to aggressively price New Glenn by accounting for booster reusability, it could pose a threat to SpaceX’s own business strategy. If SpaceX is unable to recoup its investment in reusability before New Glenn is regularly conducting multiple commercial missions per year, likely no earlier than 2021 or 2022, SpaceX’s Falcon 9 pricing could be rendered distinctly noncompetitive. However, this concern seems almost entirely misplaced. SpaceX has half a decade of experience mass-producing orbital-class (reusable) rockets, (reusable) fairings, and propulsion systems, whereas Blue Origin at best has minimal experience manufacturing a handful of suborbital vehicles over a period of a few years. Blue has a respectable amount of experience with their BE-3 hydrolox propulsion system, and that will likely transfer over to the BE-3U vacuum variant to be used for New Glenn’s third stage. The large methalox rocket engine (BE-4) that will power New Glenn’s first stage also conducted its first-ever hot-fire just weeks ago, a major milestone in propulsion development but also a reminder that BE-4 has an exhaustive regime of engineering verification and flight qualification testing ahead of it. Perhaps more importantly, the company’s relative success with New Shepard’s launch, recovery, and reuse has not and cannot move beyond small suborbital hops, and thus cannot provide the experience at the level of orbital rocketry. New Shepard is admittedly capable of reaching an altitude of 100km, but the suborbital vehicle’s flight regime does not require it to travel beyond Mach 4 (~1300 m/s). The first stage of Falcon 9, however, is approximately four times as tall and three times the mass of New Shepard, and boosters attempting recovery during geostationary missions routinely reach almost twice the velocity of New Shepard, entering the thicker atmosphere at more than 2300 m/s (1500-1800 m/s for LEO missions). Falcon 9’s larger mass and velocity translates into intense reentry heating and aerodynamic forces, best demonstrated by the glowing aluminum grid fins that can often be seen in SpaceX’s live coverage of booster recovery. Blue Origin’s New Glenn concept is extremely impressive on paper, but the company will have to pull off an extraordinary leap of technological maturation to move directly from suborbital single-stage hops to multi-stage orbital rocketry. Blue’s accomplishments with New Shepard are nothing to scoff at, but they are a far cry from routine orbital launch services. Translating back to the new establishment, Falcon 9 will likely remain SpaceX’s workhorse rocket for some five or more years, at least until BFR can prove itself to be a reliable and affordable replacement. This change in focus, combined with the downsides of second stage recovery and reuse on a Falcon 9-sized vehicle, means that SpaceX will ‘only’ end up operationally reusing first stages and fairings from the vehicle. The second stage accounts for approximately 20-30% of Falcon 9’s total cost, suggesting that rapid and complete reuse of the fairing and first stage could more than halve its ~$62 million price. Yet this too ignores another mundane fact of corporate life SpaceX must face. Its executives, Musk included, have lately expressed a desire to at least partially recoup the ~$1 billion that was invested to develop reuse. Assuming a partial 10% reduction in cost to reuse customers and profit margins of 50% with rapid and total reuse of the first stage and fairing, 20 to 30 commercial reuses would recoup most or all of SpaceX’s reusability investment. Musk recently revealed that SpaceX is aiming to complete 30 launches in 2018, and that figure will likely continue to grow in 2019, assuming no major anomalies occur. Manufacturing will rapidly become the main choke point for increased launch cadence, suggesting that drastically higher cadences will largely depend upon first stage reuse with minimal refurbishment, which just so happens to be the goal of the Falcon 9’s upcoming Block 5 iteration. Even if the modifications only manage a handful of launches without refurbishment, rather than the ten flights being pursued, each additional flight without maintenance will effectively multiply SpaceX’s manufacturing capabilities. More bluntly: ten Falcon 9s capable of five reflights could do the same job of 50 brand new rockets with 1/5th of the manufacturing backend. Assuming that upcoming reuses proceed without significant failures and Falcon 9 Block 5 subsumes all manufacturing sometime in 2018 or 2019, it is entirely possible that SpaceX will undergo an extraordinarily rapid phase change from expendability to reusability. Mirroring 2017, we can imagine that SpaceX’s Hawthorne factory will continue to churn out at least 10 to 20 Block 5 Falcon 9s over the course of 2018. Assuming 5 to 10 maintenance-free reuses and a lifespan of as many as 100 flights with intermittent refurb, a single year of manufacturing could provide SpaceX with enough first stages to launch anywhere from 50 to 2000 missions. The reality will inevitably find itself somewhere between those extremely pessimistic and optimistic bookends, and they of course do not account for fairings, second stages, or expendable flights. If we assume that the proportional cost of Falcon 9’s many components very roughly approximates the amount of manufacturing backend needed to produce them, downsizing Falcon 9 booster production by a factor of two or more could free a huge fraction of SpaceX’s workforce and floor space to be repurposed for fairing and second stage production, as well as the company’s Mars efforts. Such a phase change would also free up a considerable fraction of the capital SpaceX continually invests in its manufacturing infrastructure and workforce, capital that could then be used to ready SpaceX’s facilities for production and testing of its Mars-focused BFR and BFS. It cannot be overstated that the speculation in this article is speculation. Nevertheless, it is speculation built on real information provided over the years by SpaceX’s own executives. Rough estimates like this offer a glimpse into a new launch industry paradigm that could be only a year or two away and could allow SpaceX to begin aggressively pursuing its goal of enabling a sustainable human presence on Mars and throughout the Solar System. Blue Origin’s future endeavors shine on paper and their goal of enabling millions to work and live space are admirable, but the years between the present and a future of routine orbital missions for the company may not be kind. The engineering hurdles that litter the path to orbital rocketry are unforgiving and can only be exacerbated by blind overconfidence, a lesson that is often only learned the hard way. Blue Origin’s proud motto “Gradatim ferociter” roughly translates to “Step by step, ferociously.” One can only hope that some level of humility and sobriety might temper that ferocity before customers entrust New Glenn with their infrastructural foundations and passengers entrust New Shepard with their lives.

Current promises of changing everything failed for the exact reason that people who have been doing this for a long time said it would - move on to the next bullshit promise! Sounds like a great way to run a racket. At this point the biggest innovation seems to be price dumping. | ||

Importantly, the failure is not significant and was not a failure of an engine but rather of the associated test stand Ground Support Equipment (GSE). According to sources, the failure occurred ahead of an engine firing, which involved a Merlin 1D Block 5 qualification unit. https://www.nasaspaceflight.com/2017/11/spacex-static-fire-zuma-falcon-9-engine-no-issue-manifest/ | ||
