SpaceX will attempt to launch five Falcon 9 rockets in April. This includes an International Space Station (ISS) resupply mission and a mission to launch Bangabandhu-1, Bangladesh's first satellite. The Bangabandhu-1 launch is planned to be the first to use SpaceX's Falcon 9 Block 5 rocket, which may be the final major iteration of Falcon 9 before replacement by BFR.
At a South by Southwest (SXSW) panel, Elon Musk said that SpaceX could test the Big Falcon Rocket (BFR) "spaceship" as soon as the first half of 2019. The spaceship is the second stage of the complete BFR rocket, would be capable of reaching orbit without the first stage booster, and alone has over 50% more thrust than an entire Falcon 9.
The initial tests would likely be similar to the Grasshopper vertical takeoff and landing tests.
The United Launch Alliance's CEO Tory Bruno has been making his case for the upcoming Vulcan rocket and Advanced Cryogenic Evolved Stage. The system could compete against SpaceX's Falcon Heavy and BFR in the mid-2020s:
The maiden flight of the Vulcan currently is targeted for the middle of 2020. Two successful commercial launches are required as part of the government certification process, followed by a required upper stage upgrade to improve performance, either moving from two to four Centaur RL10 engines or using a different set of engines altogether. If all goes well, ULA will introduce its new upper stage in 2024, the Advanced Cryogenic Evolved Stage, or ACES, that Bruno says will revolutionize spaceflight. "This is on the scale of inventing the airplane," Bruno told reporters during the media roundtable. "That's how revolutionary this upper stage is. It's 1900, and I'm inventing the airplane. People don't even know what they're going to do with it yet. But I'm confident it's going to create a large economy in space that doesn't exist today. No one is working on anything like this."
The Vulcan will stand 228 feet tall with a first stage powered by two engines provided by either Blue Origin, a company owned by Amazon-founder Jeff Bezos, or Aerojet Rocketdyne. Blue Origin's BE-4 engine burns methane and liquid oxygen while Aerojet Rocketdyne's AR-1 powerplant burns a more traditional mixture of oxygen and highly refined kerosene.
[...] ULA plans to begin engine recovery operations after the Vulcan is routinely flying and after the ACES upper stage is implemented. Bruno said the engines represent two-thirds of the cost of the stage and getting them back every time, with no impact on mission performance, will pay big dividends. SpaceX, in contrast, must use propellant to fly its Falcon 9 stages back to touchdown. Heavy payloads bound for high orbits require most if not all of the rocket's propellant and in those cases, recovery may not be possible. As a result, SpaceX's ability to recover rocket stages depends on its manifest and the orbital demands of those payloads.
"Simplistically, if you recover the old booster propulsively then you can do that part of the time, you get all the value back some of the time," Bruno said. "Or, you can recover just the engine, which is our concept, and then you get only part of the value back, about two thirds ... but you get to do it every single time because there's no performance hit. So it really turns into math."

SpaceX can start building its "Big Fucking Rocket," now that it has officially found a home in LA. Mayor Eric Garcetti has announced on Twitter that the private space giant "will start production development of the Big Falcon Rocket (the spacecraft's tamer name, apparently)" at the port of Los Angeles. SpaceX designed the 348-foot-long behemoth to fly humanity to the moon, Mars and beyond. It will be able to carry up to  tons in payload, whereas Falcon Heavy can only carry [63.8] tons. "This vehicle holds the promise of taking humanity deeper into the cosmos than ever before," he added, along with an illustration of the company's massive interplanetary spacecraft.
Finally, it's worth noting just how shockingly busy the BFR tent was on both April 13th and 14th, as well as the 8th (the first day Pauline visited the facility). With upwards of 40 cars parked at the tent, it's blindingly clear that SpaceX is not simply using the tent as a temporary storage location – alongside the arrival of composite fabrication materials (prepreg sheets, epoxy, etc) from Airtech International, SpaceX undeniably intends to begin initial fabrication of the first BFR prototypes in this tent, although they will likely eventually move the activities to the Berth 240 Mars rocket factory. That's certainly not a sentence I ever expected to write, but it is what it is.
The BFR's height may be elongated from its planned total of 106 meters.
The Los Angeles City Council on Tuesday approved a plan allowing SpaceX to build and operate a facility at the Port of L.A., where the Hawthorne space company will produce its next-generation BFR rockets and spacecraft.
The vote gives formal approval to a plan that got the greenlight last month from the L.A. Board of Harbor Commissioners.
During a presentation to the council, L.A. City Councilman Joe Buscaino said the project could result in up to 700 new jobs.
Under the terms of the deal, SpaceX will have an initial 10-year lease with two additional 10-year extension options. The company's initial rent will be $1.38 million a year, with annual adjustments based on the Consumer Price Index, but it can offset a total of $44.1 million in rent by making improvements to the Terminal Island site at Berth 240 in its first 20 years of tenancy.
After a previously planned flight around the Moon using a Falcon Heavy fizzled out, SpaceX has announced that it will send a private passenger around the Moon using a BFR launch vehicle. More details will be announced on Monday:
On Thursday evening, without any advance notice, SpaceX tweeted that is had signed the world's "first private passenger to fly around the Moon aboard our BFR launch vehicle." Moreover, the company promised to reveal "who's flying and why" on Monday, September 17. The announcement will take place at the company's headquarters in Hawthorne, Calif.
There were only two other clues—tweets from Elon Musk himself. Was the rendering of the Big Falcon Spaceship in SpaceX's tweet new? Yes, Musk said. And was he the passenger? In response to this, the founder of SpaceX simply tweeted a Japanese flag emoji. This would seem to be a strong clue that the passenger is from Japan. Or maybe Musk was enjoying the epic Seven Samurai movie at that moment.
By announcing this on Thursday, and waiting four days to provide more details, the company has set off a big guessing game as to who will fly. Of course that is an interesting question, but we have many other questions that we'd like to see answered before that. We've included some of those questions below, along with some wild and (slightly) informed guesses. Musk even answered one of them for us.
The design of the BFS has apparently changed to include three prominent fins and an underside heat shield.
