Astroscale ships its space junk removal demonstration satellite for March 2021 mission
Japanese startup Astroscale has shipped its ELSA-d spacecraft to the Baikonur Cosmodrome in Kazahkstan, where it will be integrated with a Soyuz rocket for a launch scheduled for March of next year. This is a crucial mission for Astroscale, since it’ll be the first in-space demonstration of the company’s technology for de-orbiting space debris, a cornerstone of its proposed space sustainability service business.
The ELSA-d mission by Astroscale is a small satellite mission that will demonstrate two key technologies that enable the company’s vision for orbital debris removal. First will be a targeting component, demonstrating an ability to locate and dock with a piece of space debris, using positioning sensors including GPS and laser locating technologies. That will be used by a so-called “servicer” satellite to find and attach to a “target” satellite launched at the same time, which will stand in for a potential piece of debris.
Astroscale intends to dock and release with the “target” using its “servicer” multiple times over the course of the mission, showing that it can identify and capture uncontrolled objects in space, and that it can maneuver them for controlled de-orbit. This will basically prove out the feasibility of the technology underlying its business model, and set it up for future commercial operations.
In October, Astroscale announced that it had raised $51 million, making its total raised to date $191 million. The company also acquired the staff and IP of a company called Effective Space Solutions in June, which it will use to build out the geostationary servicing arm of its business, in addition to the LEO operations that ELSA-d will demonstrate.

3 VCs discuss space junk and what else they’re betting on right now
Space may be the final frontier, but in terms of investment, VCs are just getting started. With that in mind during TC Sessions: Space 2020 last week, we spoke to three investors who’ve been actively funding what could become tomorrow’s biggest companies to learn where they might focus next.
Sustainability is a major issue for all of their portfolio companies.
Our guests — Tess Hatch of Bessemer Venture Partners, who has long focused on the commercialization of space; Mike Collett of Promus Ventures, a venture firm that invests in deep tech software and hardware companies; and Chris Boshuizen of the venture firm DCVC and a cofounder of Planet Labs — had a lot of intriguing observations on topics, including the dangers of orbital debris, the merits of space manufacturing, and how they’d rate the U.S. government when it comes to fostering space-related innovations.
For those who missed the event, we’ve posted a video of our conversation below.
Space junk could affect long-term sustainability
Hatch, who recently co-authored an informative piece on the topic, said there’s little consensus about whether space junk is a critical matter that deserves more regulatory attention or an issue that will resolve itself through tech advancements, even while startups like Astroscale and D-Orbit are focused on the issue. The commercial industry’s expectation seems to be that space companies can regulate themselves and launch constellations without leaving pieces of launch vehicles or rocket stages in space, she said.
For her part, Hatch said it’s something to potentially invest in within a “handful of years.” At the moment, she added, “it’s not at the top of my list just due to looking for a shorter return on my investment for my LPs in the fund.”
Collett and the others stressed that in the meantime, sustainability is a major issue for all of their portfolio companies. “Everybody wants to do their job as a corporate citizen to make sure they’re not leaving anything else up there that doesn’t need to be there. Indeed, Boshuizen noted that at Planet Labs, best practices were taken very seriously.
Still, Boshuizen noted concerns about newer capital sources that might be less focused on the issue of space debris. “I don’t think everyone necessarily has the same space background,” he said, explaining that “we’re seeing a lot of outside investment from new people joining the industry, which is exciting, but also they don’t really know how important this is [and] it’s important for people to realize that they’ve got to pay attention to this.”

Microsoft debuts Azure Space to cater to the space industry, partners with SpaceX for Starlink data center broadband
Microsoft is taking its Azure cloud computing platform to the final frontier — space. It now has a dedicated business unit called Azure Space for that purpose, made up of industry heavyweights and engineers who are focused on space-sector services, including simulation of space missions, gathering and interpreting satellite data to provide insights and providing global satellite networking capabilities through new and expanded partnerships.
One of Microsoft’s new partners for Azure Space is SpaceX, the progenitor and major current player in the so-called “New Space” industry. SpaceX will be providing Microsoft with access to its Starlink low-latency satellite-based broadband network for Microsoft’s new Azure Modular Datacenter (MDC) — essentially an on-demand container-based data center unit that can be deployed in remote locations, either to operate on their own or boost local capabilities.

The MDC is a contained unit, and can operate off-grid using its own satellite network connectivity add-on. It’s similar in concept to the company’s work on underwater data centres, but keeping it on the ground obviously opens up more opportunities in terms of locating it where people need it, rather than having to be proximate to an ocean or sea.
The other big part of this announcement focuses on space preparedness via simulation. Microsoft revealed the Azure Orbital Emulator today, which provides in a computer emulated environment the ability to test satellite constellation operations in simulation, using both software and hardware. It’s basically aiming to provide as close to in-space conditions as are possible on the ground in order to get everything ready for coordinating large, interconnected constellations of automated satellites in low Earth orbit, an increasing need as more defense agencies and private companies pursue this approach versus the legacy method of relying on one, two or just a few large geosynchronous spacecraft.

Microsoft says the goal with the Orbital Emulator is to train AI for use on orbital spacecraft before those spacecraft are actually launched — from the early development phase, right up to working with production hardware on the ground before it takes its trip to space. That’s definitely a big potential competitive advantage, because it should help companies spot even more potential problems early on while they’re still relatively easy to fix (not the case on orbit).
This emulated environment for on-orbit mission prep is already in use by Azure Government customers, the company notes. It’s also looking for more partners across government and industry for space-related services, including communication, national security, satellite services including observation and telemetry and more.

Orbital debris startup Astroscale chosen by JAXA for its first space junk removal mission
Japanese orbital debris removal technology startup Astroscale is going to be working with the Japan Aerospace Exploration Agency (JAXA) on the agency’s first mission to remove some of the junk that currently exists on orbit. They’ve been selected by the agency to participate in its Commercial Removal of Debris Demonstration project (CRD2), which includes two separate mission phases that together will aim to accomplish the removal of a large body currently on orbit, the spent upper stage of a Japanese rocket.
Astroscale, which was founded in 2013, is focused entirely on cleaning up orbital space, which it sees as a necessary step for long-term sustainable activity on orbit. Space debris has become a hot-button topic in the space industry, with current projections anticipating massive increases in the number of active satellites orbiting the planet, thanks to the uptick in satellite constellation projects in the works from commercial operators including SpaceX, Amazon and OneWeb.
The JAXA mission aims to complete its first phase by the end of 2022, and Astroscale will support that phase by building, launching and operating a satellite that will observe and acquire data on the rocket upper stage that the second phase will seek to de-orbit. The goal is to find out more about its movement and the surrounding debris environment in order to set up a safe and successful removal.
“The data obtained in Phase I of CRD2 is expected to reinforce the dangers of existing debris and the necessity to remove them,” said Astroscale founder and CEO Nobu Okada in a press release. “Debris removal is still a new market and our mission has always been to establish routine debris removal services in space in order to secure orbital sustainability for the benefit of future generations. The international community is growing more aware of the risks of space debris and we are committed more than ever to turning this potential market into a reality.”
Astroscale is also already involved in other orbital debris-removal projects, and plans to launch a demonstration mission of its “End-of-Life Services” offering sometime in the second half of this year. This mission will be a world-first demo of commercial orbital debris removal if all goes to plan, a key step in proving that its technology can meet the needs of this growing opportunity.
Earlier this year, a near-miss of two defunct orbital spacecraft made headlines, and observers noted that had a collision occurred, it would’ve resulted in a new debris cloud with “at least hundreds” of new pieces of trackable debris. Astroscale and others like it could, combined with other initiatives like more granular tracking and information sharing among satellite operators, provide a much more sustainable in-space operating environment for the range of commercial activities either planned or in progress for orbital space.
