T-Mobile and Starlink to team up

SpaceX and T-Mobile today announced that sometime next year T-Mobile cell phones will use the Starlink satellite constellation to fill in any dead zones in its cell coverage.

T-Mobile says it’s getting rid of mobile dead zones thanks to a new partnership with SpaceX’s Starlink satellite internet, at an event hosted by T-Mobile CEO Mike Sievert and Elon Musk. With their “Coverage Above and Beyond” setup, mobile phones could connect to satellites and use a slice of a connection providing around 2 to 4 Megabits per second connection (total) across a given coverage area.

That connection should be enough to let you text, send MMS messages, and even use “select messaging apps” whenever you have a clear view of the sky, even if there’s no traditional service available. According to a press release from T-Mobile, the “satellite-to-cellular service” will be available “everywhere in the continental US, Hawaii, parts of Alaska, Puerto Rico and territorial waters.” The service is scheduled to launch in beta by the end of next year in “select areas,” and Sievert says he hopes it will someday include data.

The system will require Starlink’s second generation satellites, which right now also require SpaceX’s big Starship for launch. Once operational however it will work on the cell phones customers already own.

SpaceX remounts Superheavy prototype #7 on launchpad

Superheavy #7 lifted onto launchpad

Capitalism in space: Using its giant launch tower crane that Elon Musk has dubbed Mechazilla, SpaceX engineers yesterday remounted the seventh Superheavy prototype onto the orbital launchpad in preparation for more engine tests leading to its first flight.

Booster 7 has been atop this launch mount before. Earlier this month, SpaceX conducted two “static fire” tests with Booster 7, firing the vehicle up while it remained attached to the mount.

Both of those tests — which occurred on Aug. 9 and Aug. 11, respectively — lit up just a single Raptor engine (apparently, a different one each time). And Booster 7 wasn’t fully outfitted at the time, sporting just 20 of its 33 engines (opens in new tab) (the vast majority of which stayed dormant during the tests).

After the Aug. 11 test, SpaceX lifted the Super Heavy prototype off the mount and hauled it back to a processing bay at Starbase. Technicians installed the remaining 13 Raptors and got it ready for Tuesday’s move back to the pad.

The picture above was sent out by Musk on his Twitter feed. Note the number of engines at the base. The tower itself, acting as a crane, has also simplified and speeded up operations. SpaceX can now quickly move the rocket back and forth from the assembly building, without the need of separate cranes.

The company is still targeting early September for the first orbital launch, though it also still needs to stack Starship prototype #24 (seen in the background) on top of Superheavy, and then do more tests.

NASA describes Starship’s first unmanned test lunar landing

In a briefing focused on the science that could be placed on the mission, a NASA official yesterday provided a status update of SpaceX’s first unmanned test flight by Starship to the Moon.

First, the official revealed that NASA is only requiring SpaceX to demonstrate a successful landing. Take-off will not be required. Also,

Starship is not designed to fly directly to the Moon like NASA’s Space Launch System, however. Instead, the first stage puts it only in Earth orbit. To go further, it must fill up with propellant at a yet-to-be-built orbiting fuel depot. Other Starships are needed to deliver propellant to the depot.

Watson-Morgan described the Concept of Operations for Starship’s Artemis III mission, starting with launch of the fuel depot, then a number of “propellant aggregation” launches to fill up the depot, then launch of the Starship that will go to Moon.

Previously SpaceX suggested that the ship would be directly refueled by subsequent Starships, with no middle-man fueling depot. It could be either engineering had made the depot necessary, or NASA politics have insisted upon it.

Finally, the talk outlined the elevator SpaceX is developing to lower the astronauts and equipment to the ground from Starship’s top.

SpaceX to use both Falcon 9 and Starship to launch 2nd gen Starlink satellites

Capitalism in space: In a letter sent to the FCC, SpaceX has revealed that it has revised its plans for launching the second generation of Starlink satellites, and has decided to launch them with both Falcon 9 and Starship rockets.

SpaceX has decided to use a mix of Falcon 9 and Starship rockets to launch the 30,000 satellites in its proposed second-generation Starlink broadband constellation. Launching some of the satellites with SpaceX’s “tested and dependable Falcon 9” will accelerate the constellation’s deployment to improve Starlink services. SpaceX director of satellite policy David Goldman wrote in an Aug. 19 letter to the Federal Communications Commission. Goldman did not say when SpaceX could start launching the second-generation constellation, which remains subject to FCC approval.

Previously the company’s plan had been to use Starship only, essentially retiring Falcon 9 once Starship was flying. This change could be for two fundamental reasons. First, the company has been launching Starlinks on Falcon 9 like clockwork this year, at a pace that could launch as many as 2,500 Starlink satellites in 2022 alone. With about 70% of that rocket reusable, it might now seem cost effective to continue to use it, even after Starship is flying.

The second reason is more worrisome, and has to do with Starship itself. SpaceX officials might now realize that the delays being imposed by the federal regulatory leviathan on Starship development might be significant enough that it won’t be ready when they need it for the full deployment of Starlink’s second generation constellation. If the FCC approves that deployment (an approval that is presently pending), SpaceX will have to launch at least half the full constellation of 30,000 satellites by around 2024 (thought that date might have been revised slightly).

It now might be necessary to use Falcon 9, because the federal government under Biden is standing in the way of Starship development.

Of course, it is possible that the engineering challenge of building Starship might be another reason. SpaceX might have realized that the rocket will be delayed anyway, and thus needs Falcon 9 to meet its timetable as promised to the FCC.

NASA again approves design concept for Orbital Reef commercial space station

Proposed Orbital Reef space station

Capitalism in space: Sierra Space announced today that NASA has completed, apparently for the second time, the design review for the Orbital Reef space station that the company wants to build in partnership with Blue Origin and others, thus allowing the actual design of the station to begin.

This press release announcement, on August 22, 2022, is a bit puzzling, as Sierra Space made almost the exact same announcement in April 2022. What, did NASA have to do this twice? Did issues come up after the first approval? Was the agency reviewing different things?

Regardless, NASA as usual is slowing things down considerably. Sierra Space and Blue Origin, the primary partners in this private space station project, first announced it in October 2021. It took the government almost a year to simply approve the basic concept so that the design phase could finally begin. At this pace it will be 2090 before the station is launched.

SpaceX and China complete launches

Two launches have just occurred in the 2022 launch race. First, SpaceX today successfully launched another 53 Starlink satellites, using its Falcon 9 rocket.

The first stage successfully landed on its drone ship in the Atlantic, completing its ninth flight.

China in turn used its Long March 2D rocket to launch three military reconnaissance satellites, at what was the early morning hours of August 20, 2022, China time. The launch path took the rocket over China’s interior as well as Taiwan, with the first stage crashing somewhere in China.

The leaders in the 2022 launch race:

37 SpaceX
31 China
11 Russia
6 Rocket Lab
5 ULA

American private enterprise still leads China 52 to 31 in the national rankings, and the entire world 52 to 49. The 52 launches so far this year is now the fifth best total for the U.S. since the launch of Sputnik in 1957.

Firefly completes a dress rehearsal countdown of Alpha rocket; schedules launch

Capitalism in space: Having successfully completed both a full dress rehearsal countdown and static fire test of its fully stacked Alpha rocket, Firefly Aerospace has now scheduled the rocket’s launch for September 11, 2022.

These details come from a tweet by the company, so details are very limited. Nonetheless, this will be the company’s second attempt to complete an orbital launch. The first attempt, in September 2021, failed when one of its first stage engines shut down prematurely.

The company had hoped to attempt this second launch ten months ago, but was forced to delay it when the federal government demanded its chief investor, Ukrainian billionaire Max Polykov, first sell off his share in the company.

Raytheon & Northrop Grumman successfully complete the second flight of a hypersonic missile prototype

Raytheon and Northrop Grumman, working in partnership, have successfully flown a hypersonic missile prototype for the second time in eleven months.

For the latest test, the HAWC prototype was carried under the wing of an aircraft and flown to high altitude, where it was released. A solid rocket booster then accelerated the vehicle to supersonic speed and a scramjet ignited. An engine without moving parts, a scramjet uses its forward motion to compress the incoming air into a shockwave that burns with fuel, producing enough thrust to propel the missile to over five times the speed of sound.

The latest prototype had only minor modifications from the previous flight and met all of its objectives. The data recovered by telemetry will be used to improve the digital models using artificial intelligence, machine learning, and big data, which will increase the efficiency and performance as the weapon concept comes closer to practical deployment.

As this is a military project, not many details about the prototype were released, such as its size, speed, design.etc. One shouldn’t even trust the illustrations of the missile, provided by Northrop Grumman. Each shows the missile with a rounded lifting body shape on its bottom side, likely to protect and guide it on its re-entry, but there is no guarantee the illustrations’ shape matches that of the real missile.

Maritime Launch Services signs land lease for its Nova Scotia spaceport

Capitalism in space: Maritime Launch Services yesterday obtained a 20-year land lease for its Nova Scotia spaceport from the province of Nova Scotia.

The lease covers 334.5 acres, and is renewable for an additional 20 years.

Unlike other spaceports, Maritime isn’t merely providing a launch site for rocket companies. Instead the company will also launch smallsats itself, using a Ukrainian-built rocket dubbed the Cyclone-4M. Initially the plan was to fly all launches in this manner, but the invasion of the Ukraine by Russia has caused Maritime to look for other launch providers as well.
