From the PR:

LONG BEACH, Calif.–Jonathan Yaney, founder and CEO of SpinLaunch, has announced that the company has been awarded a responsive launch prototype contract from the Department of Defense (DOD), facilitated by the Defense Innovation Unit (DIU).

SpinLaunch is developing a kinetic energy-based launch system that will provide the world’s lowest-cost orbital launch services for the rapidly growing small satellite industry. In 2018, the company received $40 million in a Series A financing round from Airbus Ventures, Google Ventures and Kleiner Perkins.

The recently published State of the Space Industrial Base states that the future and growth of the U.S. space economy is “critically dependent on continuing reductions in the costs and risks associated with launch. There is a bifurcation of launch providers between lower-cost, ‘bulk’ carriers…and higher-cost, ‘niche’ providers offering lower lift-mass, but launch to a specific orbit.”

“SpinLaunch fills this gap by providing dedicated orbital launch with high frequency at a magnitude lower cost than any current ‘niche’ launch system,” stated Yaney. “This will truly be a disruptive enabler for the emerging commercial space industry. There is a promising market surge in the demand for LEO constellations of inexpensive small satellites for disaster monitoring, weather, reconnaissance, communications and other services.”

In January 2019, SpinLaunch moved from Silicon Valley to its new 140,000 square foot headquarters in Long Beach, California and last month broke ground on a new $7 million test facility on 10 acres at New Mexico’s Spaceport America. First kinetic energy flight tests are expected to occur early 2020 and the company has announced its plans for first launch by 2022.

Few technical details are known publicly about the Spinlaunch system. This image was released with the PR but it’s difficult to decipher. It appears to show the launch projectile attached to the rotating mechanism that will bring the projectile up to a significant fraction of orbital velocity.

Due to its unique technology, SpinLaunch is able to offer readily-available, low cost, dedicated launches at high frequencies. SpinLaunch is working to provide up to five launches per day at a price of $250,000 / launch.

** Orbit Fab‘s satellite water propulsion initiative begins with water sent to the ISS: Orbit Fab Becomes the First Private Company to Supply the International Space Station with Water – Orbit Fab

Within a year of securing venture funding, Orbit Fab has launched their hardware twice to the International Space Station (ISS) and supplied the station with water. Following the success of the multi-day microgravity refueling demonstration, Kenneth Shields, COO of the ISS U.S. National Laboratory, said in a statement, “With their recent successful completion of in-orbit water transfer operations aboard the space station, Orbit Fab became the first private company to supply the ISS with water using its own proprietary refueling equipment and processes. This concept of operations was not previously conceived of in the original design of the ISS, thus demonstrating NASA’s flexibility and desire to accommodate private sector clients who are utilizing the ISS U.S. National Laboratory as a steppingstone to an industrialized Low Earth Orbit.”

Using water as an in-space propellant has the advantage of being a very safe substance, which is important on the station where NASA is extremely cautious about such things.

Water was used for this propellant transfer demonstration as it is one of the most inert and easy to handle propellants available. Several companies offer satellite thrusters that use water as a propellant, among them is OrbitFab co-founder Daniel Faber’s former company, Deep Space Industries, which was recently acquired by Bradford Space. Orbit Fab plans on offering a variety of storable propellants on orbit, including water, xenon, green monopropellants, hydrazine, NTO, and hydrogen peroxide.

** The window for the next Rocket Lab Electron launch opens on June 27th.

The Make It Rain mission will launch multiple spacecraft as part of a rideshare flight procured by Spaceflight. The launch window will open in late June, with launch taking place from Rocket Lab Launch Complex 1 on New Zealand’s Māhia Peninsula.

The mission is named ‘Make it Rain’ in a nod to the high volume of rainfall in Seattle, where Spaceflight is headquartered, as well in New Zealand where Launch Complex 1 is located. Among the payloads on the mission for Spaceflight are BlackSky’s Global-4 satellite and Melbourne Space Program’s ACRUX-1 CubeSat.

** Ariane V successfully launches two satellites to GEO:

** Commercial launch industry must deal with the double challenges of the introduction of lower priced reusable rocket flight services and a drop in the number of orders for big GEO communications satellites:

It’s been a little more than three years since Space X launched the Falcon 9 reusable rocket booster B1021 on a mission to the International Space Station (ISS) in April 2016. When the rocket came back to Earth, it became the first to land vertically on a ship at sea, and then the first to be flown again, on a March 2017 SES-10 mission. Shortly before then, in November 2015, Blue Origin launched its suborbital New Shepard booster, and successfully achieved a powered vertical soft landing.

Such demonstrations have proven that it is possible to bring big payloads into Low Earth Orbit (LEO) — and potentially do so at a fraction of the cost of expendable launches.

“The big factor here is time,” notes Marco Caceres, an analyst with Reston, Va.-based consultancy Teal Group. “When you have an expendable launch vehicle, everything is brand new and you have to test everything. And typically, you don’t launch more than once a month. With reusability your check out time is less, because everything tends to work. As long as there are no cracks, you’re going to launch again within a couple of weeks.”

** Student rocket teams battle it out at the Spaceport America Cup competition in New Mexico:

** EXOS Aerospace sets June 30th for next SARGE launch from Spaceport America. This will be the third flight of the reusable sounding rocker.

** Sweden’s arctic Esrange spaceport will support reusable rocket operations:

SSC is currently developing Esrange Space Center in northern Sweden with new capabilities and services. A testbed for reusable rockets is currently being established, and SSC aims at launching small satellites in a couple of years. In addition, SSC is now introducing a new flight ticket service for suborbital space flights, accessible and affordable for both current and new types of customers. The new concept introduces both the opportunity to fly fractional payloads, ranging from only a few kg up to 800 kg, and a substantially more frequent flight schedule. The flight ticket service is carried out jointly between SSC and DLR MORABA within the EuroLaunch partnership.

Swedish Space Corporation SSC has been launching more than 560 suborbital rockets from Esrange Space Center since the 1966. At Esrange, SSC also operates one of the world largest ground stations for satellite control and data reception. This legacy gives SSC a unique position in the European space community.

For scientists and researchers using microgravity as a tool, the new flight ticket concept SubOrbital Express covers a complete set of services ranging from a flight ticket including launch, quick and safe land recovery to customized services such as design and development of experiment payload modules.

The Spaceport Sweden project is a separate initiative aimed towards suborbital space tourism. The goal is to enable spaceflight participants one day to view the aurora from a Virgin Galactic SpaceShipTwo or other high altitude vehicle.

SpaceX has a webpage dedicated to the STP-2 Mission:

…this mission will deliver 24 satellites to space on the DoD’s first ever SpaceX Falcon Heavy launch vehicle. The STP-2 mission will be among the most challenging launches in SpaceX history with four separate upper-stage engine burns, three separate deployment orbits, a final propulsive passivation maneuver and a total mission duration of over six hours. In addition, the U.S. Air Force plans to reuse side boosters from the Arabsat-6A Falcon Heavy launch, recovered after a return to launch site landing, making it the first reused Falcon Heavy ever flown for the U.S. Air Force.
