In addition to its expanded rideshare launch program, SpaceX also announced an agreement with in-space transportation company Momentus Aug. 22. Momentus will fly its Vigoride tug on a SpaceX dedicated rideshare mission, allowing satellites with a total mass of up to 250 kilograms to fly to custom orbits after deployment from the Falcon 9. SpaceX identified Momentus as its first customer for a dedicated rideshare mission."We are showing that ridesharing from the Falcon 9 will be a game-changer. By ferrying payloads to multiple orbits from a single launch, we multiply the capability of an already very impressive system," said Mikhail Kokorich, chief executive of Momentus, in the statement announcing the agreement.

ЦитироватьSingapore startups' NuX-1 cubesat to be orbited via Momentus, SpaceX
By Deyana Goh -
February 7, 2020

              Singapore startups Aliena and NuSpace  have signed a launch service agreement with US-based Momentus for their  NuX-1 cubesat, to be orbited during the first quarter of 2021.


Under the agreement, Momentus will use their Vigoride orbital  transfer vehicle to propel NuX-1 to its final orbit using the company's  water plasma thrusters, after launching onboard a SpaceX Falcon 9 rocket  from Vandenberg, California.


The 3U cubesat will demonstrate autonomous orbit control maneuvers  using Aliena's ultra-low power miniature Hall-thruster as well as  NuSpace's Attitude Determination & Control Systems (ADCS) that comes  equipped with an autonomous orbit control system. The nanosatellite  will also carry an Internet-of-Things (IoT) payload for NuSpace.


"We are honored to be carrying out the orbital placement of the very  first satellite for two innovative startups from the burgeoning  Singaporean newspace industry," said Mikhail Kokorich, CEO of Momentus.  "We trust this is a foundational step toward future partnerships with  local space companies who, like Momentus, are pushing the limits of  technology and exploring uncharted territories."


Zhen Ning, CEO of NuSpace, added: "I believe that this partnership is  just the beginning of greater things to come for NuSpace and Aliena. It  demonstrates that Singapore, albeit being a small nation, has local  talents and capabilities to support a space industry that through  collaborative initiatives will allow the local space sector to  thrive.The extended partnership with Momentus is very important for  NuSpace as it demonstrates our capabilities to innovate with  international partners and create truly unique commercial solutions."


"From Aliena's point of view, most of our customers are constellation operators – or look to run applications that acquire data from a fleet of satellites managed by Aliena. To that note, the solution offered by Momentus provides an accelerated way to rapidly populate and operationalize constellation services while reducing fuel requirements onboard miniature platforms, hence allowing users to dedicate more real-estate for in-orbit operations, as well as to better utilize onboard fuel for advanced manoeuvres", said Mark Lim. "We too believe that this working relationship with NuSpace and Momentus will serve as a springboard to better serve the needs of the International Commercial Space community in the days to follow."

ЦитироватьMomentus announces customers for in-space shuttle service
by Debra Werner — February 4, 2020  

Momentus  plans to deploy a SteamJet cubesat on the Vigoride demonstration  mission scheduled to launch later this year on a Russian Soyuz rocket.  Shown here, Vigoride undergoing vibration testing. Credit: Momentus    Mountain View, Calif. – SteamJet Space Systems is the latest customer to sign up for Momentus' Vigoride space transportation service.


Momentus announced plans at the SmallSat Symposium here to deploy a  SteamJet cubesat on its Vigoride demonstration mission scheduled to  launch later this year on a Russian Soyuz rocket. SteamJet, a United  Kingdom propulsion startup founded in 2017, builds water-fueled  resistojet propulsion for small satellites and cubesats.


"It's a pleasure to be working with Momentus on launch integration  and using their technology for our final orbital placement," SteamJet  CEO Pavel Savin said in a statement. "Momentus has created a fantastic  efficiency-to-cost ratio. We look forward to continuing the relationship  with future SteamJet satellites."


SteamJet's 1.5-unit cubesat will be integrated into a deployer  designed to fit multiple cubesats built by Innovative Solutions in Space  of the Netherlands. The deployer will then be mounted on Momentus'  Vigoride transfer vehicle, Dawn Harms, Momentus chief revenue officer,  said by email.


Once in orbit, SteamJet intends to demonstrate a propulsion system  that uses water or another low pressure, non-toxic, non-corrosive fluid  propellant to create thrust. SteamJet houses its propulsion system in a  module shaped like a tuna can that attaches to the exterior of a  cubesat.


"We are excited to be a part of SteamJet's important flight  heritage," Momentus CEO Mikhail Kokorich said in a statement. "Momentus  and SteamJet share the goal of expanding the current mission  capabilities of smallsats, enabling satellites to stay in space longer."


Momentus launched its first 16-unit cubesat mission  in 2019. The firm plans to conduct two Vigoride missions in 2020 to  demonstate "in-orbit servicing maneuvers and payload deployment  capabilities," Harms said.


SteamJet and startup NuSpace of Singapore are the first two customers  to announce rides on Momentus' shuttle service, which includes launch  arrangements and transfer from the rocket's drop-off point to another  orbit. Momentus plans to begin offering quarterly shuttles to  sun-synchronous and mid-inclination in 2021, according to its website.


In total, Momentus has five customers lined up for shuttle flights in  2020 and 2021. Five more customers, including Deimos and Exolaunch, have signed up for Momentus charter flights to destinations not served by shuttle flights.


Singapore startups NuSpace and Aliena  plan to send their joint NuX-1 demonstration satellite on Momentus'  Vigoride orbital transfer vehicle after it launches in early 2021 on a  SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California. 


NuX-1 is a mission designed to demonstrate autonomous  orbit control maneuvers with Aliena's miniature Hall-thruster and  NuSpace's attitude determination and control system. The NuX-1 triple  cubesat also will house an an Internet-of-Things (IoT) payload for  NuSpace, which plans to establish an IoT constellation.


Momentus won a U.S. Air Force Small Business Innovation Research  (SBIR) Phase I contract to accelerate work on in-space transportation  services and satellite upper stage technologies. Momentus did not reveal  the value of the SBIR contract awarded through a streamlined SBIR  process developed by the Air Force Research Lab and AFWERX, an Air Force organization focused on innovation.

ЦитироватьMomentus signs in-space transportation pact
by Debra Werner — February 5, 2019  

Artist's rendering of Momentus Vigoride moving a satellite to a new location in low Earth orbit. Credit: Momentus    MOUNTAIN VIEW, CALIFORNIA – Exolaunch, the German launch services  provider formerly known as ECM Space, signed a contract to pay in-space  transportation startup Momentus more than $6 million to move satellites  in low Earth orbit in 2020 with a service called Vigoride and from low  Earth to geosynchronous orbit in 2021 with Vigoride Extended.


With Vigoride, Exolaunch will send "cubesat and microsatellite  constellations to multiple orbits, giving clients an unprecedented  flexibility of satellite deployment, reducing the price of launch, and  giving access to orbits not typical for ridesharing vehicles," Dmitriy  Bogdanov, Exolaunch chief executive, said in a statement. "We also plan  to deliver smallsats to geosynchronous orbit using the Vigoride Extended  service. Momentus will enable us to service a larger segment of the  market by enabling our customers to reach custom orbits in an efficient  and cost-effective manner."


Vigoride, with a preliminary pricetag of $1.2 million, is designed to  move satellites with a mass of 250 kilograms or less to  new destinations in low Earth orbit. For example, "you could put  different satellites at different altitudes," Mikhail Kokorich, Momentus  founder and president, told SpaceNews at the SmallSat Symposium.


Vigoride Extended, with a preliminary price of $4.8 million, will  move satellites with a mass of 300 kilograms from low Earth orbit to  geostationary transfer orbit, geostationary orbit or the moon, said  Kokorich, the entrepreneur who founded Russian small satellite builder  Dauria Aerospace, co-founded Astro Digital, an Earth imaging and analysis firm, and invested in Helios Wire, a satellite-enabled internet-of-things startup.


Momentus plans to conduct an in-orbit demonstration of its key  technology, a water-plasma engine, in March or April. After extensive  laboratory testing, Momentus engineers are confident the technology  works but this type of water plasma engine has never flown in space,  said Negar Feher, Momentus product and business development vice  president.


Momentus' orbital transport vehicle is housed in a 61 by 71 by 25 centimeter aluminum bus with a fueled mass of 80 kilograms.


In addition to the Exolaunch contract, Momentus has nonbinding  letters of intent worth about $400 million for its in-space  transportation services, Feher said.


Momentus, a firm founded in Santa Clara, California, in 2017, raised $8.3 million in seed funding last year.

ЦитироватьService Roadmap for Vigoride
2.5.2020

2020 is a big year for Momentus, as our Vigoride shuttle will fly two demo missions, paving the way for commercial missions from 2021 onward.

Through joint efforts in flexible ridesharing this will open a new paradigm in flexibility for custom drop-off altitudes and orbits in space. You can read about some of our first customers on Space News here and here.

The first ever water-powered microwave electro-thermal (MET) thruster was launched and tested in space on our El Camino Real mission in 2019. The first full-scale Vigoride test mission "Strait of Magellan" is planned for Q3 2020 on the Soyuz rocket. Another planned ride is titled "Amber Road" in December 2020 on the SpaceX dedicated rideshare mission.

What all of this means is a very exciting future for satellite owners and operators with regards to price and efficiency. Whereas our Charter Service includes only an orbital transfer and requires the customer to procure a launch, our Shuttle Service includes launch provisions and the orbital transfer. More options...flexibility, and savings ultimately!

After demos are completed in Q3/Q4, quarterly launches will be available in 2021 and beyond.

ЦитироватьMomentus and EnduroSat sign two launch agreements
by Debra Werner — June 16, 2020

SAN FRANCISCO – In-space transportation provider Momentus announced agreements June 16 with Bulgaria's EnduroSat to provide transportation for two cubesats scheduled to launch on a SpaceX Falcon 9 rideshare flight in February 2021.
Under the agreement, Momentus will enclose Kuwait's first spacecraft, QMR-KWT, and EnduroSat's Shared Platform for Applied Research and Technology Affirmation (SPARTAN) in its Vigoride orbit transfer vehicle for the Falcon 9 launch. At the conclusion of the Falcon 9 flight, Vigoride will transport the cubesats to different orbits.
SPARTAN, a six-unit cubesat, is home to seven technology demonstrations and commercial payloads, according to a June 16 news release. EnduroSat intends the mission to serve as a pilot for its Shared Satellite Service.
For Shared Satellite Service missions, EnduroSat plans to handle integration, validation, testing, launch and operations of the satellite and payloads. EnduroSat customers will have access to payload data in the cloud through a digital ground station, according to the news release.
"The goal is to provide easy access to space for visionary entrepreneurs, scientists and technologists, helping them drive innovation at the final frontier," EnduroSat CEO Raycho Raychev said in a statement. "EnduroSat is proud to cooperate on this pilot mission with the team of Momentus, and we look forward to the next missions."
The agreements signal Momentus' expansion in Eastern Europe as well as the Middle East through its partner EnduroSat, Momentus CEO Mikhail Kokorich said in a statement.
QMR-KWT is an educational mission funded by the Kuwaiti company Orbital Space and EnduroSat. Students around the world will write software to be uploaded to one of the satellite's onboard computers, according to the news release.
Momentus purchased rides on five SpaceX Falcon 9 smallSat rideshare missions in 2020 and 2021 to showcase the ability of its Vigoride in-space transportation vehicle to move customer satellites 300 to 1,200 kilometers beyond the drop-off point.

ЦитироватьSpace startup Momentus provides 'last mile delivery' for satellites launched on any rocket
Published Thu, Jul 2 20201:41 PM EDT

Key Points
  • Space startup Momentus has so far struck $40 million worth of customer contracts this year and announced on Thursday its latest deal with Dutch small satellite specialist ISILaunch.
  • The company offers a "last mile delivery" service for spacecraft, tapping into the growing small satellite market.
  • "From a single launch we can drop into multiple orbits, and just change altitude or change inclination, dropping you in several spots. Basically increasing the flexibility of a big rocket launch dramatically," Momentus CEO Mikhail Kokorich told CNBC.

A space startup offering a "last mile delivery" service for spacecraft is continuing its deal spree this year, becoming an increasingly important player in the growing small satellite market.
Momentus, a Santa Clara, California-based company, has so far struck $40 million worth of customer contracts this year and announced on Thursday its latest deal with Dutch small satellite specialist ISILaunch. Its the eighth such deal Momentus has unveiled in 2020, with the company providing its orbit transfer services for ISILaunch on a SpaceX Falcon 9 launch in December.

The core of Momentus' business is Vigoride, a simple vehicle that consists of frame, an engine, solar panels, avionics and a set of satellite deployers. The company calls it a transfer vehicle, akin to the delivery truck that would bring a package to its final destination after a large cargo aircraft delivered it to the airport. The Momentus transfer vehicle is especially important for satellites that hitch a ride on large rockets, an increasingly popular industry practice called ridesharing. Additionally, the company touts its transfer vehicles as adaptable to essentially any rocket available on the market.
The Momentus service essentially shuttles spacecraft from a rocket to each spacecraft's intended final orbit, in what Momentus CEO Mikhail Kokorich explained as an "extremely cost efficient manner."
"Vigoride is especially designed to use big rockets to distribute satellites in low Earth orbit," Kokorich told CNBC. "From a single launch we can drop into multiple orbits, and just change altitude or change inclination, dropping you in several spots. Basically increasing the flexibility of a big rocket launch dramatically."

Momentus

The company launched its first demonstration mission last year, which proved that the key part of its transfer vehicle — the water plasma engines — worked. It has the first two missions for Vigoride lined up this year, currently slated for launch on a Russian Soyuz rocket in the third quarter and a SpaceX Falcon 9 rocket in December. 
Momentus has raised nearly $50 million in capital to date, from investors including Prime Movers Lab and Y Combinator. It's grown to more than 60 employees quickly after its founding in 2017.

Although its water plasma engines are key to Momentus' business, Kokorich emphasized his operation is "not a propulsion company."

"We're a delivery service," Kokorich said. 
Momentus pointed to market analysis by consulting firm Northern Sky Research, which issued a report in November 2019 that gave a very bullish forecast on the market for small satellites. The number of satellites launched each year has steadily grown, the report found, from 70 satellites in 2010 to 493 satellites in 2019 — and Northern Sky expects that to reach over 1000 a year by 2030.
Likewise, the report found that Momentus' initial target market — small satellites launched to low Earth orbit, one of the most common destinations — would grow from less than $250 million in 2018 to about $750 million in 2020 and nearly $1.5 billion by 2024. That's why Kokorich plans for Vigoride to be just the first of an increasingly more capable fleet of transfer vehicles that Momentus offers.
"In the big picture, we would like to build the infrastructure for industrialization beyond Earth in space," Kokorich  said. "The first step is developing a last mile delivery in space transportation."

"As a next step we need in our vehicles to deliver like stuff to high orbits, like other activities that can be an extremely unique service," Kokorich added.
He believes the cost of transportation "is always the enabler of any industry." The cost of launching satellites has steadily dropped, which Kokorich attributed to the competitive pricing that SpaceX has introduced with its largely reusable rockets.
"The larger the rocket you have, the more efficient you can launch the payload, because the proportion of the rocket mass is less," Kokorich explained. "And the side of rocket reusability as a technology is pushing the price for rocket launches much lower."

The market for Momentus' transfer vehicles comes into play due to satellites becoming smaller and smaller, but needing a way to get from the orbit the rocket drops them off in to the orbit the spacecraft will operate in. Kokorich noted that small spacecraft have also created a market for smaller rockets, such as those by Rocket LabVirgin OrbitAstra, and Relativitiy
"That service is really valuable but it's kind of like a private jet, when you need to be going very fast. The small rockets will forever be more expensive than large rockets," Kokorich said.
Momentus is therefore focused on those rideshare customers, who want a cheap way to get to orbit but need a boost to get to the precise destination. 
"It's essentially created the need for last mile delivery, so [small satellites can use big rockets. It will not substitute in all cases small rockets, because sometimes you need to fly fast. But if you don't need to fly fast, if you just need to deploy your stuff, you can do this much cheaper with Vigoride," Kokorich said.

ЦитироватьDeployers from Netherlands-based ISISpace will launch with satellites pre-integrated on Vigoride.
July 2, 2020 by Andreia

2nd July 2020 – Santa Clara, CA — Momentus (www.momentus.space), a provider of in-space transportation services for satellites, and Innovative Space Logistics BV (ISILAUNCH), a launch services subsidiary of Netherlands based ISISpace, announced today the execution of a launch agreement for 5 Vigoride shuttle services from 2021 through 2022.
The agreement includes the first launch onboard the SpaceX Falcon 9 rideshare mission in December 2020, with additional launches to be scheduled over the 2021-2022 time frame. ISILAUNCH is focused on the provision of frequent and fully serviced launches for CubeSats and microsatellites since 2009 and to date they have executed or supported numerous launch campaigns on various launch vehicles, successfully sending 380 satellites into orbit.

"This partnership is of great importance to both ISILAUNCH and Momentus", said Mikhail Kokorich, CEO of Momentus. "It provides ISILAUNCH with the ability to offer precision orbital insertions and enables greater efficiencies for some of our mutual customers to pre-integrate their satellites into QuadPack deployers at ISILAUNCH's facilities in Europe prior to shipment to Momentus for Launch. For Momentus, it gives us access to new markets and generates a steady flow of business volume to help fill our launch manifest." 
"Through this partnership, with the orbit transfer and insertion services offered by Momentus, we are able to offer even greater flexibility to our customers with launches to the orbit their mission requires, while still enjoying the benefit of low cost rideshare launches. Based on our vast experience with launching small satellites, ISILAUNCH can support Momentus to select the right combination of orbits and customers for each ride", says Abe Bonnema, ISILAUNCH director. "With Momentus having selected our deployer range as baseline, we look forward to a fruitful cooperation to best serve the small satellite community needs together."
A graduate of the prestigious Y Combinator program and based in Santa Clara, California, Momentus announced a $25.5MM Series A raise last year, bringing total funding to nearly $50M. Momentus employs new and proprietary technologies, including water plasma propulsion to enable revolutionary low-cost orbital shuttle and charter services. The prototype of the Vigoride vehicle, "El Camino Real", was launched and tested last year. The first full-scale Vigoride test mission is planned for Q4 of 2020 on the SpaceX dedicated rideshare mission. 
About Momentus
Momentus is the first company providing in-space transportation services for satellites. The company was founded in 2017 in Santa Clara, CA. Momentus designs and builds transfer vehicles propelled by proprietary water plasma thrusters.

Нет, по крайней мере сейчас. Первичный источник энергии - солнечные батареи. Хотя в дальней перспективе, особенно при полётах к внешним планетам, может быть использован и реактор. Но здесь есть проблема - плазменный двигатель имеет принципиально меньший УИ, чем ионный или, тем более, термоядерный, зато большую тягу. Поэтому плазменный двигатель намного эффективнее ионного для полётов ГСО, на Луну, и на Марс Хотя необходимо учесть дешевизну и доступность воды как рабочего тела (а вода в этом двигателе именно рабочее тело), возможно и дальше, по крайней мере для грузовых перевозок, для которых стоимость перевозки важнее времени в пути.

Цитата: Zhilinsky Valerij от 05.07.2020 13:40:38плазменный двигатель имеет принципиально меньший УИ, чем ионный
а это откуда следует?
Из метода разгона рабочего тела. Ионный двигатель - своего рода ускоритель, где ионы ускоряются под действием электрического поля, плазменный - своего рода микроволновка, где плазма разогревается микроволновым излучением. Поэтому скорость истечения рабочего тела у ионного двигателя (а следовательно и УИ) больше, зато при одинаковой мощности тяга меньше.
   
И тут возникает своего рода засада. Большой УИ тем выгоднее, чем длительнее работает двигатель, и выясняется, что для Луны, например, классический ионный двигатель имеет слишком большой УИ и маленькую тягу, поэтому полёт будет длительным. Отсюда интересное следствие - для классического полёта к Марсу и обратно плазменный двигатель тратит слишком много рабочего тела. Но ситуация меняется, если на орбите Марса есть возможность заправиться рабочим телом на обратную дорогу...
