Superheavy prototype #7 undergoes 14 engine static fire test

SpaceX’s seventh prototype of its Superheavy first stage booster — intended to launch its Starship orbital craft on the first orbital flight — successfully completed a 10-second static fire test of 14 of its 33 engines yesterday.

I have embedded video of the test below the fold. It shows the burn repeatedly from different angles. It appears the engine test went exactly as planned, with no subsequent fires near the launch pad.

According to the article at the link, this test fire, even with only 14 engines, made this Superheavy booster the most powerful rocket on Earth, at least until tonight when NASA’s SLS launches. Once this booster fires all of its 33 Raptor-2 engines however it will then exceed SLS in power. That it hasn’t launched however makes this claim a little overstated.

Regardless, SpaceX continues to move quite smoothly towards that first orbital launch of Starship, which the company hopes to do before the end of the year.

ABL scrubs first launch attempt

The rocket startup ABL yesterday scrubbed its first attempt to launch its new RS1 smallsat rocket from Alaska, due to “off-nominal data on the first stage during propellant loading.”

This test launch carries two cubesats for a customer, but its prime mission is to demonstrate the rocket’s ability to put those smallsats into orbit.

The company is trying again today, but is providing no live stream of the countdown or launch. We can only wait for updates.

Several major rocket companies to the FCC: stay out!

In response to the proposal by managers at the Federal Communications Commission (FCC) that it regulate satellite operations despite having no actual legal authority to do so, a cohort of major rocket companies as well as others have responded in firm opposition.

Major space companies, including SpaceX and Relativity, are urging the U.S. Federal Communications Commission (FCC) to stick to its purview β€” spectrum usage β€” as it looks to potentially update its rules for in-space servicing, assembly and manufacturing (ISAM) missions.

There is plenty that the FCC could β€” and should do β€” to support ISAM missions that sit squarely within its regulatory bounds, the companies said. SpaceX and others, as well as startups like Orbit Fab, which wants to build refueling depots in space, and Starfish Space, which is developing a satellite servicing vehicle, submitted recommendations related to spectrum and ISAM. The commission also heard from Blue Origin, Lockheed Martin, United Launch Alliance and other space companies and industry groups.

…Relativity Space and the industry association Commercial Spaceflight Federation separately argued that the FCC’s involvement in issues outside of those related to spectrum could result in duplicative approvals processes. These could be especially challenging for smaller startups and newer space entrants to navigate.

It is likely that if the FCC tries to impose regulations outside of its legal authority, one or more of these companies are going to sue to nullify those regulations, and will likely win. In the process nothing will be gained, and much lost. Thus, this advice from the industry makes great sense, and the FCC and the Biden administration should stop playing empire-building games and focus on what it is legally supposed to do.

CAPSTONE successfully enters lunar orbit

CAPSTONE successfully entered orbit around the Moon today, putting it into the planned Lunar Gateway halo orbit to test operations in that location.

CAPSTONE is now in a near-rectilinear halo orbit, or NRHO. This particular NRHO is the same orbit that will be used by Gateway, the Moon-orbiting space station that will support NASA’s Artemis missions. CAPSTONE is the first spacecraft to fly an NRHO, and the first CubeSat to operate at the Moon.

Mission engineers plan two more engine burns over the next five days to refine the orbit more precisely.

China launches environmental satellite

Using its Long March 6 rocket, China early today launched what China’s state-run press claimed was an environmental satellite for “atmospheric and marine environment surveys, space environment surveys, disaster prevention and reduction, and scientific experiments.” Whether that is true is anybody’s guess.

The leaders in the 2022 launch race:

52 SpaceX
50 China
19 Russia
9 Rocket Lab
8 ULA

American private enterprise now leads China 75 to 50 in the national rankings, and trails the rest of the world combined 78 to 75.

FYI, posting is late today because today Diane and I were out hiking, having fun.

China launches Tianzhou freighter to Tiangong-3 space station

Earlier today China successfully used its Long March 7 rocket to launch the fifth Tianzhou freighter to its Tiangong-3 space station.

At 12:10 p.m., Tianzhou-5 conducted a fast automated rendezvous and docking at the rear docking port of the space station’s core module Tianhe. This is the first time that China’s cargo craft has completed a fast automated rendezvous and docking in about two hours, setting a world record, according to Pan Weizhen, a designer of the cargo craft system from the China Academy of Space Technology.

The leaders in the 2022 launch race:

52 SpaceX
49 China
19 Russia
9 Rocket Lab

SpaceX launches two Intelsat communications satellites

Using its Falcon 9 rocket SpaceX today successfully launched two Intelsat geosynchronous communications satellites into orbit.

The first stage completed its 14th flight, but was not recovered. This was not a failure, but intended because the rocket needed the fuel to instead get the satellite into its proper geosynchronous orbit.

The leaders in the 2022 launch race:

52 SpaceX
48 China
19 Russia
9 Rocket Lab
8 ULA

American private enterprise now leads China 75 to 48 in the national rankings, and only trails the rest of the world combined 76 to 75.

China: We like dumping out-of-control rockets on your head!

China has now signaled that it intends to ramp up the launch rate of its Long March 5B rocket, its most powerful rocket but also a rocket with a core stage that falls to Earth out-of-control after each launch, risking injury and damage to others.

Liu Bing, director of the general design department at the China Academy of Launch Vehicle Technology (CALT), told Chinese media that the the Long March 5B, designed for launches to low Earth orbit, would be used together with the Yuanzheng upper stage series to launch multiple satellites for constellations.

Though not clearly stated, the launcher and YZ-2 combination could be used to help deliver high numbers of satellites into orbit for the planned national β€œguowang” satellite internet megaconstellation.

It is very possible that with the addition of an upper stage, engineers could reconfigure the rocket so that the first stage is shut down and separated earlier so that it immediately falls into an ocean drop zone following launch. At the same time, making sure that drop zone is always over the ocean might be difficult for some polar launches.

What China really has to do is to upgrade the engines on the core stage so that they can be restarted. At present these engines can only be started once, and once shut down they are dead. If the stage reaches orbit — which it has done on all previous launches — there is then no way to control it, and since that orbit is unstable the stage crashes to Earth, who knows where, shortly thereafter. With restartable engines the stage could easily be de-orbited properly.

China has expressed utter contempt for the complaints of other nations about these out-of-control crashes, claiming the risk is infinitesimal. While quite small, it still exists.

Ted Muelhaupt of the Aerospace Corporation said in July that the odds of debris from the reentry following the launch of the Wentian module ranged from one in 230 to one in 1,000. This was more than an order of magnitude greater than internationally accepted casualty risk threshold for the uncontrolled reentry of rockets of one in 10,000, stated in a 2019 report issued by the U.S. Government Orbital Debris Mitigation Standard Practices.

Small or not, China is a signatory to the Outer Space Treaty, and every out-of-control crash has been a violation of that treaty. This behavior clearly makes China a rogue nation, not to be trusted.

Advanced Space wins lunar orbiter contract with Air Force

Advanced Space, the company that is presently running the CAPSTONE mission that will arrive in lunar orbit on November 13th, has won a $72 million contract with the Air Force Research Laboratory to build and operate a new experimental lunar orbiter.

The mission, dubbed Oracle, is targeting a 2025 launch and will operate in lunar orbit for two years.

β€œOur primary goals for the program are to advance techniques to detect previously unknown objects through search and discovery, to detect small or distant objects, and to study spacecraft positioning and navigation in the XGEO realm,” said James Frith, the principal investigator. XGEO refers to the space beyond geosynchronous orbit out to the moon. Oracle will operate in the vicinity of Earth-moon Lagrange Point 1, about 200,000 miles from Earth. The GEO belt, by comparison, is about 22,000 miles above Earth.

An additional goal of Oracle is to help mature AFRL’s green propellant technology. β€œWhile there are no specific plans yet to refuel Oracle, AFRL wants to encourage civil and commercial development of on-orbit refueling services,” said Frith.

The federal government’s transition from the building rockets, spacecraft, and satellites to simply buying them from the private sector continues. In the past, when the Air Force attempted to design and build everything, a project like this would have cost at least five times more and taken two to five times longer to get launched. Now, it hires Advanced Space to do it, and gets what it wants quickly for lower cost.

UK govt requests public comment on Shetland spaceport

The Civil Aviation Authority (CAA) of the United Kingdom, tasked with regulating space operations, has requested public comment on the environmental impact of the proposed Shetland spaceport, dubbed SaxaVord and presently under construction.

Shetland Islands Council granted planning permission in February, with Lockheed Martin and Skyrora among the companies looking at launching satellites, as early as next year.

One of the environmental considerations is for no launches or tests between mid-May and the end of June to avoid disturbing breeding birds. U nst’s 135 bird species include red-throated divers, merlins, puffins and Arctic terns.

The spaceport has said it expects to conduct at least 30 launches a year, once operational. That number is probably optimistic.

Meanwhile, it is beginning to appear that — at least in these early stages — the CAA is not going to be helpful to Great Britain’s effort to develop a space industry. Not only does this action suggest it is not enthused about this spaceport and is putting up barriers to it, it has slow-walked the licensing of the Virgin Orbit launch from Cornwall, costing that company so much money because of the delay that its liquidity was threatened.
