SpaceX and the company’s drone ship Of Course I Still Love You (OCISLY) have successfully wrapped up their second Falcon 9 recovery in less than two weeks, bringing booster B1051 back to Port Canaveral to be broken over and refurbished for a second launch.

Following its support of Crew Dragon’s thus far flawless launch debut, the booster will likely be exceptionally easy to turn around for its next flight. That second launch could occur as early as late April for Cargo Dragon’s 17th mission, a consequence of NASA’s desire to keep its SpaceX missions on boosters that are ‘in family‘ (i.e. only new boosters or flight-proven boosters that have only launched NASA payloads).

Although B1051’s reentry profile was relatively slow and gentle with main engine cut-off (MECO) and booster separation occurring at ~1.9 km/s (4250 mph) and 85 km (53 mi), its recovery was made intriguingly difficult by high seas at drone ship OCISLY’s Atlantic Ocean station. These bad conditions were readily visible at several points during SpaceX’s DM-1 livestream, with OCISLY heeling several degrees as the Falcon 9 booster’s Merlin 1D engine lit up the surrounding area like a floodlight. In fact, B1051’s post-landing struggle could actually be seen live as the booster clearly slide several meters across the drone ship’s deck almost immediately after touching down.

This issue of boosters sliding about and generally being difficult to deal with is actually one of the leading motivations that lead to SpaceX developing Octagrabber, a tank-like robot used to remotely secure recovery Falcon 9 first stages while minimizing the risk to the recovery team. In a situation like DM-1, with B1051 already sliding around OCISLY’s deck immediately after a night landing, Octagrabber would nominally be remotely activated and controlled, crawling from its garage to grab Falcon 9’s hold-down clamps and secure the stage with its own weight.

It’s actually unclear whether Octagrabber is capable of this sort of remote operation without SpaceX technicians aboard OCISLY, nor if SpaceX – as of late – has even tried to attempt to secure Falcon 9 boosters at night. The process of transferring crew between ships in heavy seas is actually quite dangerous on its own, so it would be less than surprising to hear that SpaceX’s recovery managers have cut down on nighttime operations in bad weather if Octagrabber can only be operated with crew present on OCISLY. For B1051, the drone ship, a tugboat, and crew boat GO Quest remained in the vicinity of the landing target until the following morning (still March 2nd) before beginning the ~500 km (~300 mi) trek back to Port Canaveral. Greeted by moody low-hanging clouds and scattered showers, observers were actually able to capture the rare sight – as pictured above – of Octagrabber being driven back into its blast shield/garage.

Regardless, future Commercial Crew launches – aside, perhaps, from SpaceX’s second demonstration launch (DM-2) later this year – will likely be able perform return-to-launch-site (RTLS) landings at the company’s Florida landing zones, much like Falcon 9 boosters already do after Cargo Dragon (CRS) missions. According to VP of Mission Assurance Hans Koenigsmann, B1051 had to conduct a drone ship (ASDS) recovery at sea due to NASA’s desire for conservative performance reserves to guard against the potential (and extremely unlikely) failure of one or several Merlin engines during the launch’s boost stage. In 2012, Falcon 9 suffered its first and only (known) in-flight Merlin failure, an anomaly which the rocket’s autonomously avionics perfectly dealt with to save the primary mission (Cargo Dragon’s operational debut, CRS-1). A secondary Orbcomm communications satellite sadly failed to make it to its operational orbit, however, classifying the mission as a partial failure. More recently, there have been unconfirmed hints pointing to other potential in-flight Merlin 1D failures, albeit during booster recovery attempts instead of the main boost phase. Whether or not those anomalies actually occurred, NASA is clearly all about extreme conservatism and ‘safety first’ approaches for the Commercial Crew Program (or at least SpaceX’s side of it).

SpaceX’s successful recovery of B1051 marks the company’s third launch and landing of 2019, thus far averaging a relatively slow one mission per month. While schedules can change, it currently appears that Crew Dragon’s DM-1 orbital debut will be the only SpaceX launch in March, barring Falcon Heavy’s own commercial debut occurring in the last few days of the month. According to a SpaceX representative speaking earlier this year, the company is actually aiming to equal or even surpass its 2018 record – 21 launches – in 2019, requiring a minimum average of two launches per month for the remainder of the year.

Numbers aside, SpaceX’s 2019 calendar will undoubtedly aim to surpass the number of major company milestones in a single year, a hard act to follow after 2017 and 2018. Ranging from the first operational Starlink satellite launches and the first SpaceX launch with astronauts aboard to major flight test and developmental milestones for the company’s next-gen Starship spaceship and Super Heavy booster, there are an incredible wealth of events to look forward to.

SpaceX scores another massive Pentagon deal to support military satellites

Published

on

By

SpaceX just picked up another $1.6 billion from the Pentagon, with the U.S. Space Force awarding two task orders worth $1.6 billion to fly 18 Falcon 9 missions from Vandenberg Space Force Base in California through the end of 2027. The launches will carry satellites for the Space Based Sensing and Targeting portfolio, a set of programs meant to help the military detect and track airborne threats and relay that information across forces in near real time.

The award falls under National Security Space Launch Phase 3 Lane 1, the Space Force’s faster, commercial style procurement track for missions that do not require the military’s most demanding certification process. It is also the largest single order publicly disclosed under that program so far, and the first task order issued since the Space Force nearly tripled Lane 1’s contract ceiling from $5.6 billion to $17 billion on July 17.

SpaceX to become America’s Military data backbone for missiles, drones, and warfighters

Eric Zarybnisky, the Space Force’s acting portfolio acquisition executive for space access, said the entire process, from identifying the requirement to signing the contract, took about two months, including a month set aside for companies to prepare proposals.

SpaceX is not just launching these satellites. It already holds the contracts to build two of the programs within the same portfolio, $4.16 billion for the Space Based Airborne Moving Target Indicator system and $2.29 billion for the Space Data Network Backbone, which Teslarati covered in May. That means SpaceX is now responsible for both building key pieces of the military’s next generation sensing network and getting them into orbit.

With this latest award, SpaceX’s Pentagon contract total for 2026 alone tops $8 billion, adding to a defense portfolio that already includes the Golden Dome missile defense software group SpaceX joined in April and a string of GPS launches it inherited after ULA’s Vulcan rocket ran into a booster anomaly, which we detailed in March.

Lane 1’s vendor pool technically includes seven companies: SpaceX, ULA, Blue Origin, Rocket Lab, Stoke Space, Impulse Space, and Relativity Space. In practice, SpaceX remains the only provider with the combination of launch cadence, flight proven Falcon 9 hardware, and West Coast infrastructure to support a campaign requiring roughly one Vandenberg launch a month for the next year and a half.

Some lawmakers have flagged the growing concentration of national security launches with one company as a risk worth watching. For now, the Space Force keeps backing SpaceX, with it being the company that shows up ready to launch.

Elon Musk sheds two new bits of detail on Starship after 13th test launch

Elon Musk shed two new bits of detail on Starship following its 13th test launch, which was an overwhelming success.

SpaceX launched Starship for the 13th time last Friday after two delays: one on Monday when several Raptor engines did not ignite, and another on Thursday due to unfavorable weather conditions in Starbase, Texas.

The launch was overwhelmingly successful. SpaceX was able to complete a necessary test of the heat shield tiles by increasing the acceleration of Starship from launch throughout the flight; 20 Starlink v3 satellites were released with no issue; the Super Heavy Booster landed safely in the Gulf of America, Ship successfully reignited engines while in space; and it also splashed down without incident in the Indian Ocean.

SpaceX Starship just nailed something it’s never done before

Nevertheless, more details are coming out about Starship, and Musk is doing the talking.

Starship Will Be Retrieved in the Ocean

Musk revealed on Tuesday night that Starship would be recovered by a ship in the Indian Ocean. SpaceX routinely tries to recover Starship after splashdown in an effort to find out more about the flight by examining the spacecraft afterward.

This helps engineers find out more about why things might have happened, allows them to examine any potential damage or anomalies that might have occurred, and increases the chances of an even more successful flight next time thanks to the additional information recovered.

Ship Could Have Been Caught by Tower Arms, Musk claims

Musk has already indicated that SpaceX will plan to attempt a catch of Starship with the 14th test flight. While this would be a major accomplishment, it would be an expected next step, considering the fact that the Super Heavy Booster has already been caught by the chopsticks on numerous occasions.

A ship catch would be a great indication of where SpaceX stands in terms of reusability and launch cadence. A successful catch with relatively no incidents would be a good sign that SpaceX is nearing a more frequent launch of Starship, but also that the reusability of the massive rocket would be something many would expect in the near future.

It is a necessity to make life multiplanetary.

Elon Musk updates the SpaceX timeline for Mars

Published

Elon Musk has updated his timeline for when humans will walk on Mars and for when ships will simply get there.

The objective of getting to Mars has been one of Musk’s biggest goals since becoming a serial entrepreneur and realizing that time on Earth is limited. Musk has said several times he hopes to die on Mars, and not by impact.

Musk now believes that people will be on Mars in “roughly 5 to 7 years.” He said that a Mars lander will get there “a few years sooner.”

The response from Musk comes after NASA Administrator Jared Isaacman said that SpaceX’s biggest priority is the Moon and not Mars. Because of this, Isaacman conceded that he believes nuclear power and propulsion investments will provide “potentially the pathway with the fewest miracles required to put four people on Mars in the next 10 to 15 years.”

Of course, this is what NASA can do through taxpayer funding and nuclear investments, he added.

Musk’s grand ambitions are much more optimistic than most, and it is certainly a double-edged sword. This is not the first time timelines for Mars have been somewhat lofty, especially to those normal thinkers like you and me, not super geniuses like Musk.

SpaceX Board has set a Mars bonus for Elon Musk

In fact, the SpaceX and Tesla frontman has said on at least a dozen occasions that we could be on Mars in the coming years. Musk said 2020 would be the big year as early as 2009. In 2020, he was “highly confident” of a landing in 2026, and had even said 2024 in a best-case scenario.

The point is, the range has varied, and it’s anyone’s guess when we’ll get there. This latest adjustment to the timeline is typical of Musk, and while the Moon has seemingly taken priority over Mars, it is still worth mentioning that the ultimate goal is to make life multiplanetary, and it starts potentially with the Red Planet.
