Tag: Falcon 9

SpaceX tonight successfully launched a commercial communications satellite. They did not recover the first stage because the seas were too rough to send out the drone ship.

The leaders in the 2018 launch standings:

7 China
5 SpaceX
3 Japan
3 ULA
2 Russia

Though I have removed Rocket Lab as an American company, crediting it instead to New Zealand, the U.S. still has 8 successful launches total, one more than China.

Link here. The article contains lots of good information and background, including some cost figures that suggest this recovery scheme will only work if they can recovery a lot of fairings while doing a lot of launches. Since SpaceX’s goal is to do a lot of launches, the numbers seem reasonable.

They also intended to try to recover the rocket’s fairing, but they did not telecast this, and there is no word yet whether they were successful. In fact, their low-key approach here suggests a shift in policy. Previously, SpaceX was eager to show off its test programs. Now, this silence suggests a desire to throttle back on that openness, possibly in order to protect their proprietary engineering.

Update: It appears that at least one fairing half landed in the water intact, though that also means they were unable to catch it. According to a Musk tweet at the link, the fairing missed the ship net by “a few hundred meters.” Musk also indicates the need for larger chutes in the future. Either way, I wonder if the fairing in the water can still be reused.

The 2018 launch standings:

7 China
4 SpaceX
2 ULA
2 Russia
2 Japan

As a nation, the U.S. now has 7 launches total, tying China.

Link here. The article has some additional excellent images, but it was this paragraph that I thought was most significant:

To oversimplify, after launch, the payload fairing separates (mechanically) from the second stage once Falcon 9 or Heavy has left behind the majority of Earth’s atmosphere. After separation, each fairing half orients itself for a gentler reentry into the atmosphere with cold nitrogen gas thrusters, likely the exact same thrusters used in part to achieve Falcon 9’s accurate and reliable landings. Due to their massive surface area and comparatively tiny weight, fairing halves effectively become exceptionally finicky and awkward sails falling through the atmosphere at insane velocities, with the goal generally being to orient each half like a boat’s hull to provide some stability. Once they are low enough, assuming they’ve survived the journey from TEN TIMES THE SPEED OF SOUND and 62 MILES above Earth’s surface to a more reasonable ~Mach 0.5 and maybe 5 miles of altitude, the fun parts begin. At this point, each fairing half deploys a GPS-connected parachute system (a parasail, to be exact) capable of directing the massive hunks of carbon fiber and aluminum to a very specific point on the surface of the ocean.

What we don’t yet know is whether SpaceX will have cameras on the fairing, and if so, whether they will make those images available to the public, during launch.

Capitalism in space: SpaceX will include two test smallsats for its planned internet constellation of more than 11k satellites when launches a Spanish radar satellite in two days.

The FCC gave SpaceX permission for the test in November, and new documents now show that SpaceX will piggyback Microsat-2a and Microsat-2b onto its launch of a Spanish radar satellite called Paz. The mission is set to lift off from the Vandenberg Air Force Base in California on Saturday at 9:14 a.m. ET aboard a Falcon 9 rocket, according to Spaceflight Now.

Ajit Jai, chairperson of the FCC — the government entity which must ultimately approve SpaceX’s plans — endorsed the effort on Wednesday. “Satellite technology can help reach Americans who live in rural or hard-to-serve places where fiber optic cables and cell towers do not reach,” Pai told Reuters in a statement.

A lot of news sources have made a big deal about Jai’s endorsement, as if that endorsement guarantees FCC approval of SpaceX’s gigantic constellation. It doesn’t, though it certainly helps.

Capitalism in space: SpaceX today successfully launched Luxembourg’s first government satellite, GovSat 1.

The launch used a previously flown first stage, which was intentionally not recovered on this flight. They did however land it in the ocean, probably to simply practice the entire routine.

The 2018 launch standings:

5 China
2 SpaceX
2 ULA
1 Rocket Lab
1 Europe
1 India
1 Japan

This launch puts the U.S. and China in a tie for the lead. I must also note that the world’s aerospace industry completed 13 launches in the first month of 2018. If this pace is maintained, we shall see about 150 launches in 2018, the most since before 1980, and possible the most in a single year ever. (I need to check the records for the 1970s, as it is possible but very unlikely this number was topped during that time.)

Capitalism in space: SpaceX successfully placed a top secret government satellite into orbit tonight, completing the first launch of 2018.

As has become routine, they also successfully landed the first stage on their launchpad at Cape Canaveral. You can watch the replay here.

Numerous news articles today have noted that last night’s launch by SpaceX of ten Iridium satellites produced a somewhat unusual light show for Californians. Reader Frank Kelly sent me some images he took, noting,

I was able to catch the booster ascent, stage separation, second stage burn and what looks like the booster spinning with at least one engine firing. The spinning went on for a while so it must have had some fuel left.

I read SpaceX said they would not land this booster so maybe they had some fun with it for us folks in LA. It spun around for a minute like a pinwheel. A great show.

The image above right is one of his images, reduced in resolution to post here. Below that is a cropped section of the full resolution image, showing the “pinwheel” being performed by the first stage. And as other readers of BtB have also noted, the launch crew was clearly performing engine tests and maneuvers with this first stage, all the way down to the ocean.

As is typical of SpaceX, they waste no opportunity to test their equipment and find out what it can do, on the extreme. I suspect these maneuvers were designed to push the first stage’s ability to recover from an out-of-control spin. From the call-outs by engineers during the launch, it appears that this test was a success, as it appears from those call outs that the first stage “landed” properly upright in the ocean.

Let me add that in reviewing some of the youtube videos posted by my readers in the comments below, I also think these first stage maneuvers might be tests in preparation for the first Falcon Heavy launch, which will involve landing three first stages at the same time, two landing very close together at Kennedy. The flight tests yesterday could be an effort to demonstrate how well they can program those first stages for their return.

Capitalism in space: SpaceX today successfully launched ten 10 Iridium satellites.

This launch for Iridium reused a first stage from a previous Iridium launch. This was the first time Iridium launched with a used first stage. SpaceX did not try to recover the stage, which could be for several reasons, including the possible desire by the customer that they devote their entire effort to getting the satellites in orbit.

This was also SpaceX’s last launch for the year. The launch standings for the year now are thus:

29 United States
19 Russia
18 SpaceX
15 China

Sometime in the first week of 2018 I will post a full table showing this year’s launches plus the launch totals going back to the early 1980s. It reveals a great deal about the history of the launch industry for the past half century, as well as where that launch industry is likely heading in the coming half century.

Capitalism in space: In its current round of stock sales SpaceX had raised another $100 million in investment capital.

In August, the space exploration company sold $349.9 million worth of shares, a Securities and Exchange Commission (SEC) filing showed. That amount has now risen to $449.9 million, a new filing showed on Monday, adding an extra $100 million onto the current fundraising effort.

The latest injection of cash values SpaceX at $21.5 billion, according to Equidate, a platform that facilitates the trading of shares in private technology firms. SpaceX was not immediately available for comment on the valuation when contacted by CNBC.

If I was a big money investor I too would be interested in buying some SpaceX stock. Meanwhile, Aviation Week is reporting that the first Falcon Heavy launch has slipped to 2018. I am not surprised, but I have also not seen any other news reports on this, so I am withholding judgement.

Capitalism in space: According to SpaceX’s CEO, they plan to up their annual launch rate by 50% in 2018, and hope to average 30 to 40 launches per year thereafter.

They also hope to introduce their Big Falcon Rocket (BFR) by 2022, but will continue operations with both the Falcon 9 and Falcon Heavy, if that is what their customers prefer.

The expected Falcon 9 launch this past week of the mysterious Zuma government payload, built by Northrop Grumman but linked to no government agency, has been postponed indefinitely because of a fairing issue identified during testing for a different customer.

This delay also suggests that this may be an issue that will delay more than one launch, which could effect SpaceX’s effort to achieve 20 launches in 2017.

Capitalism in space: NASA revealed today that it is close to approving the use of a Falcon 9 reused first stage for the next Dragon cargo mission to ISS.

During a press conference at NASA’s Wallops Flight Facility here Nov. 10 about the launch of a Cygnus cargo mission to the ISS, a NASA manager said the agency would likely approve the use of a reused booster on that mission, designated SpX-13, assuming it clears an upcoming review. “We’re in the final stages of doing all those assessments,” Dan Hartman, ISS deputy program manager, said. SpaceX first requested to use a previously-flown booster for a cargo mission about a year ago. “On the NASA side, we’ve had a lot of major reviews.”

He said SpaceX itself had one more readiness review for the booster they’re planning to refly before deciding if they can use it for the SpX-13 mission, scheduled for launch Dec. 4. “If that comes back positive,” he said, “I’d say the chances are that we’ll be flying a reuse on SpX-13.”

It appears that about a year from now the use of reused boosters will have become completely normalized, with no one thinking anything unusual about their use. This, after almost a half century of old-school engineers and managers repeatedly saying such a thing made no sense and was impossible in terms of engineering and economics.

Capitalism in space: SpaceX yesterday successfully launched a South Korean communications satellite while also successfully landing the first stage on a barge.

This was the company’s sixteenth launch in 2017, doubling their previous high of eight in 2016. This places the company one behind the Russians in the race to complete for the most launches in 2017.

The drone barge used by SpaceX to successfully land a 1st stage during its October 11 launch was subsequently damaged by a fire on board during the return to port.

The exact series of events is unclear, but it is understood the booster leaked some of its residue RP-1 fuel, which flowed along the deck of the ASDS and pooled near the containers at the aft of the drone ship.

The booster then continued post-landing operations, designed to safe the booster ahead of crews boarding the ship to complete the safing process ahead of the trip back to port. At some point shortly after landing there was an ignition of the pooled RP-1, likely via the purging of the Triethylaluminum-Triethylborane (TEA-TEB) that is used as the first stage ignitor. This has to be purged as part of the safing procedures for allowing crew near the rocket. Fire hoses – staged on the deck of the ship – quickly doused the fire. However, the garage containing the robot – nicknamed “Roomba” or “OctaGrabber” (among other names) – was caught in the fire and damaged.

This was confirmed by the lack of the robot in view under the rocket during the ASDS’ return to Port.

It appears they are repairing the damages and that future barge landings will not be affected.
