NASA awards small orbital tug study contracts to six companies

8:35 am

NASA yesterday awarded six companies small study contracts in connection with orbital tug operations, with some to study using their rocket upper stage for this purpose while others to see how they can refine the use of their tugs.

The press release was not entirely clear on how much money was involved in each contract, though in each case the amounts are relatively small.

The firm-fixed-price awards comprise nine studies with a maximum total value of approximately $1.4 million. The awardees are:

Arrow Science and Technology LLC, Webster, Texas [tug study]
Blue Origin LLC, Merritt Island, Florida [both tug and upper stage studies]
Firefly Aerospace Inc., Cedar Park, Texas [tug study]
Impulse Space Inc., Redondo Beach, California [tug study]
Rocket Lab, Long Beach, California [both tug and upper stage studies]
United Launch Services LLC, Centennial, Colorado [upper stage study]

The studies are expected to be finished by September 2025, and will be used by NASA to determine how it will get some of its future spacecraft to their intended orbits.

Orbital tug startup Impulse Space wins contract with satellite company SES

3:15 pm

The orbital tug startup Impulse Space has won a contract to use its Helios tug to transport the satellites of the long established Luxembourg company SES to their correct orbit after launch.

The companies announced May 22 that they signed a multi-launch agreement that starts with a mission in 2027 where Impulse’s Helios kick stage, placed into low Earth orbit by a medium-class rocket, will send a four-ton SES satellite from LEO to GEO within eight hours. The announcement did not disclose the vehicle that will launch Helios and the satellite, or the specific SES satellite.

The agreement, the companies said, includes an “opportunity” for additional missions to transport SES satellites to GEO or medium Earth orbits.

This the first satellite tug contract for Impulse’s Helios tug, which is the larger of the company’s two tugs, the smaller version dubbed Mira. While Mira has completed an orbital demo mission, Helios has not yet flown, though it has three planned launches beginning in 2026.

Firefly wins Space Force contract to test orbital maneuvers with its Elytra space tug

12:33 pm

Firefly yesterday announced it has been awarded a Space Force contract to use its Elytra space tug to test orbital maneuvers designed for military purposes.

As part of the mission, Elytra will host a suite of government payloads, including optical visible and infrared cameras, a responsive navigation unit, and a universal electrical bus with a payload interface module. Firefly’s Elytra Dawn configuration will utilize common components from the company’s launch vehicles and lunar landers, including the avionics, composite structures, and propulsion systems, to enable on-demand mobility, plane changes, and maneuvers with high delta-V capabilities and reliability.

Though unstated, the inclusion of cameras suggests the Pentagon wants to test Elytra’s ability to maneuver close to other satellites and photograph them.

This contract further illustrates Firefly’s effort to diversify its space products. Like Rocket Lab, it is not relying solely on its rocket division to make money, but is also developing and selling a range of space products, from lunar landers to orbital tugs to satellite equipment.

Orbital tug startup Impulse Space buys three SpaceX Falcon 9 launches

12:53 pm

The orbital tug startup Impulse Space announced yesterday that it has signed a contract with SpaceX for three Falcon 9 launches in order to fly its Helios orbital tug as well as its smaller Mira tug on several commercial missions.

The first launch, planned for mid-2026, will be the first flight of Helios. The transfer vehicle will transport the company’s smaller Mira vehicle, carrying a commercial optical payload, from low Earth orbit to geostationary transfer orbit on the Victus Surgo mission for the Space Force and Defense Innovation Unit. Impulse Space received a $34.5 million contract for Victus Surgo and another mission, Victus Salo, Oct. 3. Impulse Space said the schedule and payloads for the other two Helios launches will be determined later.

This development signals a major shift in the nascent orbital tug industry. Up until now the varous tug companies would buy launch space on rockets as secondary payloads. This I think is the first time a tug company has purchased the rocket itself as the primary payload, giving it the ability to control the rocket in order to make its tug operations more precise for all of its customers.

Orbital tug startup D-Orbit raises another 150 million euros

8:44 am

The orbital tug company D-Orbit announced today that it was able to extend its more recent round of fund-raising by 50 million euros, and raise a total of 150 million in private investment capital instead.

Japan’s Marubeni Corp. led the Series C round. Marubeni has exclusive rights to distribute D-Orbit’s services in Japan in Southeast Asia, according to the news release.

New and existing investors participating in the round include: Avantgarde, CDP Venture Capital, Iberis Capital, Indaco Venture Partners, the European Innovation Council, Neva, Phaistos Investment Fund, Primo Ventures and Seraphim Space Investment Trust. Also joining the round was a consortium led by United Ventures that included the European Investment Bank and the European Investment Fund.

I call the company a “startup” in the headline, but that probably is now incorrect. It already has flown fourteen orbital tug missions, with seven more scheduled in 2025. At this point it is well established, and could extend this most recent funding round.

D-Orbit newest orbital tug deploys four smallsats

10:24 am

The Italian orbital tug company D-Orbit has now successfully deployed four smallsats from its newest tug, having been launched on August 16, 2024 on a SpaceX Falcon 9 rocket.

The tug still has one more satellite to deploy, after which it will remain in orbit as it also carries four additional customer “hosted” payloads that are using the tug itself as their service module.

This is D-Orbit’s second demo mission, the first flying in 2023. It also appears be completely successful, which puts this company in an excellent position to garner future contracts from many small satellite companies. It is also a partner in a $256 million Italian project to test in-orbit robotic satellite repair.

Orbital tug startup Astroscale expands partnership with European aerospace giant Airbus

9:36 am

The Japanese-based orbital tug startup Astroscale has signed an agreement with the European company Airbus to expand their partnership beyond an earlier agreement to use Airbus’s robot arm on Astroscale’s tug.

Under the MoU, Astroscale and Airbus will explore ways to boost the development of navigation and docking technologies for satellite servicing and debris removal missions they did not specify. According to the news release, the expanded partnership seeks to combine Airbus’s satellite manufacturing and space systems heritage with technologies Astroscale is developing for in-orbit servicing.

Astroscale has been aggressively working to get business both in Europe and the U.S. by opening divisions in both regions. This deal is clearly part of that effort. It also provides Astroscale resources as a new startup it previously did not have.

Orbital tug startup Impulse Space increases the kinds of satellites it will offer rides to geosynchronous orbit

9:16 am

The orbital tug startup Impulse Space, founder by former SpaceX engineer Tom Mueller, has announced new plans to make it possible for its tugs to take more kinds of satellites to geosynchronous orbit.

First, the company is revising the design of its larger Helios tug, set to do its first commercial mission in 2027, to carry multiple satellites ranging in weight from 300 to 5000 kilograms. Second, it is upgrading its already-flown smaller Mira tug so that it can be attached to Helios and act as a secondary tug once Helios gets to geosynchronous orbit.

The first Mira demo mission, launched in November 2023, had some communications and software issues but was still considered an overall success. The next mission will fly later this year.

The Japanese orbital tug start-up Astroscale announced yesterday that it is becoming a publicly traded company on the Tokyo stock market, beginning June 5, 2024.

The company plans to offer 20.8 million shares in the initial public offering, but has not announced a share price. According to filings with the exchange, Astroscale will set that price May 27.

Astroscale has raised more than $375 million through a series of private rounds, most recently a $76 million Series G round in February 2023. That funding has primarily come from Japanese investors, including a strategic investment by Mitsubishi Electric in that Series G round.

The company has also won two major contracts with Japan’s space agency JAXA, building its two ADRAS-J missions to first rendezvous and survey an abandoned upper stage (as shown to the right) and then fly a grapple mission to de-orbit that stage sometime in the future.

Momentus is now selling a version of its orbital tug simply as a service module for satellites

9:09 am

The orbital tug company Momentus has discovered that it can make money selling a version of its orbital tug simply as a service module, or bus, for commercial and military satellites.

The company announced Aug. 2 that it was now offering customers a bus called the M-1000. The bus is similar to the Vigoride orbital transfer vehicle that Momentus has flown three times so far, but without the water-based propulsion system it uses for changing orbits.

The bus emerged from limitations flying hosted payloads on Vigoride, which remain attached to the tug rather than deployed as satellites. Rob Schwarz, chief technology officer at Momentus, said in an interview that the company started gauging interest a year ago in hosted payloads on Vigoride, including from U.S. government agencies. “What we’re finding is that a lot of government customers don’t really want to borrow the bus and lease it, but instead they want to own it,” he said. “Also, in some cases, because of the sensitivity of the payloads they don’t want to share it with other users.”

That led Momentus to instead consider a version of Vigoride that would be a satellite bus sold to customers instead of provided as a service. It uses many of the same subsystems, like avionics and power, as Vigoride. Changes include improved pointing and options for third-party chemical and electric propulsion systems.

This is just good and smart business practice. Momentus has a product that doesn’t appeal to some customers, in its designed iteration. Rather than trying to deny reality, the company quickly accepted the situation and revised its product in a somewhat easy way so it can be sold to those customers.

Momentus completes deployment of all payloads launched on board its Vigoride-6 tug

9:14 am

Momentus yesterday announced that it has successfully completed deployment of all the payloads that were launched in April on its Vigoride-6 orbital tug.

So far, in three demonstration missions in fourteen months, the company has deployed fifteen customer satellites using its Vigoride tug, though two were sent into an incorrect orbit because of a “human error in the mapping of a software command.”

The company next two missions are presently scheduled to be launched in November 2023 and February 2024.

Startup orbital tug company experiences technical issues on demo flight

9:36 am

The first test rendezvous and docking of two smallsats built by the startup orbital tug company Starfish Space and space station startup Launcher/Vast are facing significant technical issues because both spacecraft are spinning in an unexpected manner.

Soon after Orbiter SN3 separated from the Falcon 9 upper stage, it experienced an anomaly that set it spinning at a rate on the order of one revolution per second, far outside the bounds of normal operating conditions.

By the time Launcher’s team made contact with Orbiter, fuel and power levels were critically low — and the team made an emergency decision to deploy Otter Pup immediately. In a joint statement issued today, Launcher and Starfish Space said that quick action “gave the Otter Pup mission a chance to continue.”

With assistance from Astro Digital and ground station partners, Starfish’s team contacted Otter Pup and determined that it was generating power — but was also spinning because of the circumstances of its emergency deployment.

The plan had been to deploy Otter Pup and have it rendezvous and then dock with Orbiter, demonstrating the maneuverability of both spacecraft as well as their docking equipment. The spinning now threatens the company’s ability to do this. Over the next few months engineers will make attempts to slow the spinning of Orbiter, but it is unlikely a docking can now be attempted.

Momentus test orbital tug successfully raises orbit using water-ionized thrusters

9:29 am

Momentus’s Vigoride test orbital tug has successfully raised its orbit using a ion thrusters that use water as their fuel, proving that the tug can be used to bring smallsats launched as secondary payloads to their preferred orbits.

According to tracking data, Vigoride-5 is in an orbit at an average altitude of 524.3 kilometers as of late May 7, about two kilometers higher than it was in early April, when the maneuvers started. The vehicle’s orbit had been gradually decaying since its launch in early January on the SpaceX Transporter-6 smallsat rideshare mission, descending about five kilometers before the maneuvers started.

The test of the MET is a major milestone for Momentus, which is relying on the technology to propel its tugs that will deliver satellites to their desired orbits. Technical problems with its first tug, Vigoride-3, launched nearly a year ago, kept the company from testing the MET on that vehicle.

Vigoride-5 is carrying a single smallsat, for Singapore-based Qosmosys, that it will release, although the companies have not disclosed the planned orbit for that spacecraft. The tug will also operate a hosted payload from Caltech to demonstrate space-based solar power technologies for several months.

The company already has another Vigoride in orbit that launched in April, carrying its own set of payloads for orbital transport.

Momentus reports successful use of its new water-based thrusters on its orbiting Vigoride-5 tug

8:55 pm

The orbital tug startup Momentus on March 23, 2023 reported the successful use of its new water-based thrusters on its orbiting Vigoride-5 prototype tug, proving the design works.

The Reaction Control System operates using the same propellant and tank with water as the Vigoride spacecraft’s primary MET propulsion system. The MET is designed to use water as a propellant and produce thrust by expelling extremely hot gases through a rocket nozzle. Unlike a conventional chemical rocket engine, which creates thrust through a chemical reaction, the MET is designed to create a plasma and thrust using microwave energy. When operational, the MET will be used to raise the orbital altitude and inclination of Vigoride-5.

Essentially this is a variation of an ion engine. The thrust will be low, but very efficient. The thrusters can therefore fire for a very long time, building up accelerations infeasible for chemical engines, and thus allowing the tug to significantly change the orbits of satellites in ways that was previously impossible.

This release came out the day before NASDAQ announced that Momentus has six months to raise the price of its stock above one dollar or be delisted from the stock exchange. Since its release, the stock price rose from $0.54 to $0.63, still below a dollar but going in the right direction, despite the NASDAQ announcement.

Another orbital tug & servicing company raises investment capital

9:29 am

Starfish Space, a new entrant into the orbital tug & servicing industry, has successfully raised $14 million in new investment capital, in addition to the $7 million it had raised in a previous fund-raising round.

The company hopes to launch a test satellite later this year, dubbed Otter Pup, which will undock from the orbital tub of another company, Launcher Space, do maneuvers, and then redock.

Starfish’s plan calls for Otter Pup to be sent into orbit this summer as a rideshare payload on SpaceX’s Transporter-8 mission. The spacecraft will be deployed from Launcher Space’s Orbiter space tug, and then will execute a series of maneuvers with a xenon-fueled electric propulsion system to move away from the tug.

If all goes well, the Otter Pup will return to the vicinity of the Orbiter, and then use an electrostatic-based capture mechanism to latch onto a docking target on the space tug. It could take months to test out the Otter Pup’s systems and tweak them as necessary for its test hookups.

Though the company says it will offer tug services once operational, it appears it is mostly aiming for the satellite robotic servicing market. It, like Astroscale, has developed its own docking capture device, which it will try to convince satellite companies to attach to their satellites. It will then use this to dock and service those satellites. Since these capture devices are proprietary, the number that each company gets onboard satellites will determine that company’s future sales.

This orbital servicing industry appears to be growing very quickly, now that launch costs have come down by about 90% since the arrival of SpaceX. For example, the orbital tug company Momentus is getting ready to launch its third mission.

First orbital tug from the startup Launcher fails shortly after deployment

1:18 pm

The first orbital tug, dubbed Orbiter SN1, of the startup company Launcher failed shortly after deployment from a SpaceX Falcon 9 rocket on January 3, 2023.

The vehicle communicated with a ground station on its first scheduled pass after deployment while on battery power. “We also communicated with the vehicle for the duration of expected battery life,” the company said.

However, the Hawthorne, California-based company said the spacecraft could not get into the proper attitude so that its solar cells could generate power, which it blamed on “an orientation control issue caused by a fault in our GPS antenna system.” That, in turn, kept Orbiter from deploying its satellite payloads.

The tug was carrying payloads from eight customers, four of which were satellites to be deployed while the others would remain on the tug, using it as the base of operations.

The company presently has plans to launch upgraded tugs on two different Falcon 9 launches, in June and October respectively.

German rocket startup Isar Aerospace gets first American customer

9:28 am

The German rocket startup Isar Aerospace, which hopes to complete the first launch of its Spectrum rocket this year, has signed its first launch contract with an American company, the satellite broker and space tug company Spaceflight.

U.S.-based launch services provider Spaceflight said Jan. 25 it has booked a dedicated launch in 2026 from Isar Aerospace, the German rocket developer aiming to perform the first test flight of its Spectrum vehicle this year. The mission is slated to lift off from Isar’s launchpad in Andøya, Norway, to sun-synchronous orbit (SSO).

Their agreement also includes an option for an additional dedicated launch in 2025, which Isar chief commercial officer Stella Guillen told SpaceNews could also use a launchpad it is developing at the Guiana Space Center near Kourou, French Guiana.

Spaceflight has been scrambling to find rockets for its tugs, since SpaceX announced in March 2022 it would no longer carry them. It signed a deal with Arianespace to fly on its Vega rocket, but launch failures have delayed its launch.

Isar is one of three German rocket startups vying for business. The race to be the first to launch remains very tight.

Impulse’s first demo space tug scheduled for launch

10:14 am

Impulse Space announced on January 4, 2023 that it has now scheduled the launch of its first demo space tug, Mira, for the fourth quarter of 2023.

Impulse Space said its LEO Express-1 mission, using a transfer vehicle it is developing called Mira, is manifested for launch on SpaceX’s Transporter-9 rideshare mission currently scheduled for launch in the fourth quarter of 2023. LEO Express-1 will carry a primary payload for an undisclosed customer.

Barry Matsumori, chief operating officer of Impulse Space, said in an interview that the mission can accommodate additional payloads, like cubesats. The mission profile is still being finalized, but he said the vehicle, after making some initial deployments, may raise its orbit, then lower it to demonstrate operations in what’s known as very low Earth orbit, around 300 kilometers.

After this demonstration flight the company has plans for additional flights in 2024. This tug will then join a growing fleet of companies offering this orbital transport capability to cubesats.

Orbital tug company signs launch agreement with German rocket startup Isar Aerospace

9:24 am

The German rocket startup company, Isar Aerospace, has now signed a launch agreement with a French orbital tug company, Exotrail, to put multiple tugs into orbit over a five year period.

The companies announced Nov. 3 they signed a launch services agreement to launch Exotrail’s spacevan vehicle on Isar’s Spectrum rocket on multiple missions between 2024 and 2029. The launches will take place from Andøya, Norway, and Kourou, French Guiana. The companies did not disclose a specific number of launches or the value of the agreement.

Exotrail will apparently act as the agent to get the satellite customer by providing that customer transportation to the desired orbit after deployment from Isar’s rocket.

This is the second orbital tug launch contract that Isar has won, with the first from the Italian company D-Orbit. Both deals will fly on Isar’s rocket Spectrum, which it hopes to launch for the first time next year.

Satellite about to burn up because Sherpa orbital tug has done nothing

8:46 am

Capitalism in space: A Boeing cubesat satellite launched last month is about to burn up as it returns to Earth because the Spaceflight Sherpa orbital tug that was supposed to raise its orbit has as yet done nothing.

Spaceflight planned to use a chemical propulsion system on the Sherpa, provided by Benchmark Space Systems, to raise the orbit of the vehicle to an altitude of 1,000 kilometers. The Sherpa payload, initially not disclosed by Spaceflight, is a V-band communications demonstration by Boeing called Varuna.

However, tracking information from the U.S. Space Force shows that Sherpa has yet to raise its orbit. Atmospheric drag has caused that orbit to gradually decay, and the spacecraft was most recently tracked in an orbit of 283 by 296 kilometers. That raised concerns that the spacecraft could reenter in a matter of weeks if it does not start firing its thrusters.

Spaceflight officials explain the lack of action is because they are still “commissioning” the tug, whatever that means. It also appears that problems was this same propulsion system caused SpaceX to ban Spaceflight in March as a customer on future rideshare launches.

Merger deal between Italian orbital tug company D-Orbit and Breeze canceled

8:52 am

Capitalism in space: The merger deal between the Italian orbital tug company D-Orbit and the special purpose acquisition investment company (SPAC) Breeze has been canceled.

The Italian company had hoped to raise $185 million from the deal to expand staff and accelerate investments in ION Satellite Carrier, its orbital transfer vehicle (OTV) that completed its first commercial mission in late 2020.

However, “financial markets have changed substantially” since the deal was announced Jan. 27, Breeze CEO Douglas Ramsey said, amid rising interest rates, soaring inflation, and an ongoing war in Ukraine. “As we look ahead, we remain focused on identifying another value creating opportunity for Breeze shareholders,” Ramsey added.

A SPAC is a shell company designed solely to gather investment capital that is then used to either buy or merge with another company. In the process the company that is taken over goes public, its stock available on the stock market for trade. There have been a number of such takeovers in the space sector in the past few years, but most have turned out poorly for the investors in those SPACs, as noted in the article:

Of the nine space companies that went public through SPAC mergers in 2021, only Rocket Lab’s shares finished the year trading above their price when the merger closed. [Ed: both Virgin Galactic and Astra are examples of these failures.]

Demand for new SPAC deals has also been waning amid declining investor appetite for risk and increasing regulatory scrutiny over how these blank check firms operate. More than 40 SPAC mergers have been canceled so far this year, reported Bloomberg.

To put it more bluntly, investors have found these SPACs to be poor investments, and are bailing from them. This is likely what happened at Breeze, thus forcing the cancellation of the deal with D-Orbit.

Momentus has now deployed seven of ten customer payloads from its Vigoride tug

10:59 am

Capitalism in space: Despite technical communications issues after deployment of the first test flight of its Vigoride orbital tug, Momentus yesterday announced that has now deployed seven of ten customer payloads.

This announcement is somewhat of a surprise, as in June the company had said it would not be able to deploy anymore payloads due to the communications and solar panel problems Vigoride was experiencing.

The update also noted that the company is incorporating changes in its next Vigoride tug, scheduled to launch in November.

Relativity signs deal to launch Impulse Space’s missions to Mars

10:20 am

Capitalism in space: The commercial rocket startup Relativity has now signed a deal with the orbital tug startup Impulse Space to launch at least one mission to Mars, possibly as early as 2024.

Impulse Space has announced that the company will launch the first commercial payload to Mars on board Relativity Space’s Terran R rocket. Under the new partnership, Relativity will launch Impulse’s Mars Cruise Vehicle and Mars Lander from Cape Canaveral, Florida, as part of an exclusive agreement until 2029.

The earliest anticipated launch window occurs between 2024 and 2025 and would make use of Relativity’s fully reusable Terran R rocket launching from Space Launch Complex 16 (SLC-16) at the Cape Canaveral Space Force Station.

Terran R is planned to complete the trans-Mars injection burn to place the cruise vehicle, carrying the lander, on a trajectory toward Mars. The cruise vehicle will then separate from the lander that, protected by an aeroshell, will enter the Martian atmosphere and attempt to propulsively land on the surface of the red planet.

To say that this plan is tentative is to state the obvious. First, Relativity has not yet launched its first rocket. It hopes to do so before the end of this year, but that rocket is the Terran-1, much smaller than the proposed Terran-R. Second, Impulse itself has not yet launched any tugs, though its founder, Tom Mueller, was the head engine development at SpaceX when it developed the Merlin, Draco, Super Draco, and Raptor engines. After leaving SpaceX he created Impulse Space to provide orbital and interplanetary transportation for others. It appears he has decided that an early Mars mission will be the best way to put his company on the map.

First test flight of Momentus’s orbital tug has issues

8:49 am

Capitalism in space: According to a short press release from the company, tirst test flight of Momentus’s orbital tug — launched on a Falcon 9 on May 25th, has communications issues.

We have established two-way contact with the Vigoride Orbital Transfer Vehicle, and as is often the case with a new spacecraft, have had some initial anomalies. We are using an unplanned frequency as we work through this and are applying for a Special Temporary Authority (STA) with the FCC to address that in order to help command the vehicle back to nominal configuration. Our engineering and operations team is working to address the anomalies.

No further details have so far been released.
