Amsterdam’s Orquesta raises €800,000 for no-code LLM gateway

Amsterdam-based startup Orquesta today announced an oversubscribed €800,000 pre-seed funding round. The company has developed a platform through which companies can integrate various Large Language Models (LLMs) directly into their business operations. 

Generative AI and LLMs have been developing at breakneck speed over the past year — a velocity seemingly matched  by investor appetite for all things GenAI. Indeed, just last week, Europe’s homegrown contribution in the form of Mistral 7B was made available free of charge to the public. 

Adding to the plethora of offerings, the technology itself will keep on developing rapidly (to where and to what end only time will tell). As such, organisations will undoubtedly struggle to keep up and, what’s more, quite probably end up with patchwork solutions as they try to integrate various models. (Who doesn’t love a good Frankenstein system?)  

Rather than relying on a fragmented AI tech stack, Orquesta proposes a single gateway no-code platform it says allows SaaS companies to centralise prompt management, streamline experimentation, collect feedback, and get real-time insights into performance and costs.

“The accelerated development of new AI functionalities, leads to increased fragmentation, complexity, and a need for speed within the technology landscape for our clients,” said Sohrab Hosseini, co-founder of Orquesta. “This prevents the already scarce talent of our clients from focusing on strategic work and growth.” 

Shortening release cycles

Hosseini, who founded Orquesta together with Anthony Diaz in 2022, said that with one LLM gateway, including all the necessary tooling, Orquesta was the “partner for them [clients] to remain competitive. He further added that the company was very excited about the focus and multidisciplinary experience of the various VCs and angel investors who had joined to “match and support Orquesta’s level of ambition.”

The round was led by Dutch venture capital firm Curiosity VC, while Spacetime, the investment office of Dutch entrepreneur Adriaan Mol, was co-lead. Meanwhile, angel investors include Koen Köppen (Mollie), Milan Daniels and Max Klijnstra (Otrium), and Arjé Cahn (Bloomreach). 

“Due to the acceleration of AI capabilities and adoption, we expect the landscape of LLM providers and models to grow exponentially,” said Adriaan Mol, founder of Mollie, Messagebird, and Spacetime. “Orquesta has built a best-in-class no-code platform that allows engineers to focus on their proprietary product and shorten release cycles instead of managing LLM integrations, configurations, and rules.”

It is Confirmed. M87’s Black Gap is Truly Spinning

Fifty-five million light-years away, in the galaxy known as M87, lies a supermassive black hole. It is a powerfully active black hole with a mass of 6.5 billion Suns, and in 2019 it was the first black hole to be imaged directly. The radio image captured by the Event Horizon Telescope (EHT) shows a halo of ambient light warped by the black hole’s gravity and directed our way. On one side of the halo, the light is brighter, which according to general relativity is due to the rotation or spin of the black hole. It was the first direct confirmation that the black hole rotates. A new study published in Nature has given us more rotational evidence.

It’s not surprising that M87’s supermassive black hole spins. Everything from stars to planets rotate, so astronomers expect that all black holes do as well. The challenge is proving it. Since black holes don’t have surface features, the only way you can determine black hole spin is by its torsional effect on space and time and how that affects nearby light, gas, and dust. The EHT observations are consistent with a rotating black hole, but of course, this assumes Einstein’s theory of general relativity is correct. So it would be nice to have some rotational evidence that doesn’t rely on that assumption.

This new study looks at a rotational effect known as precession. You may have noticed this effect in things like spinning tops. If you set a top spinning, you might notice that its orientation slowly shifts. The axis of rotation precesses thanks to the pull of Earth’s gravity trying to make it fall. Lots of rotating bodies precess. Earth, for example, precesses thanks to the pull of the Moon. This is why thousands of years ago the north star wasn’t Polaris, but the star Thuban in the constellation Draco.

Since M87’s black hole is active, it generates tremendous jets that stream away from the rotational poles of the black hole at nearly the speed of light. If the black hole is precessing, then the direction of those jets should change over time. This is what the new study looked for.

The team analyzed more than 17 years of radio data on the black hole’s jet and found that the jet’s orientation shifted slightly over time. It oscillates over about 10 degrees with a periodic cycle of 8 – 10 years. This means the black hole’s axis of rotation is precessing within this range. Since precession is a direct effect of rotation, this confirms the black hole rotates.

Although the team confirmed rotation, the study does raise the question of what exactly causes the black hole to precess. Earth and tops precess because they experience a gravitational tug from another body. The M87 black hole is the largest mass in the room, and there isn’t a nearby body of similar mass. So what gives? The answer could lie in the Lense-Thirring effect, also known as frame dragging. In general relativity, a rotating mass twists spacetime around it, which means anything orbiting it can have a skewed orbit. The effect is tiny for bodies such as Earth, though it has been observed. For black holes, the Lense-Thirring effect can be powerful. It’s possible that this causes the accretion disk of material surrounding the black hole to be slightly askew, and when its material is consumed by the black hole it exerts a slight torque on the black hole, causing it to precess. If that’s true, then the jets of many other supermassive black holes should see a similar effect.

What’s great about this study is that it gives us solid data on the dynamic behavior of a black hole. We don’t have to rely purely on computational models to understand how black holes interact with their environment. We can now compare models to data, which will help us not only better understand black holes, but also the galaxies in which they live.

Fever’s Aliyah Boston named unanimous WNBA Rookie of the Yr

  • Michael Voepel, ESPN.comOct 2, 2023, 11:00 AM ET

    Close

      Michael Voepel covers the WNBA, women’s college basketball, and other college sports for espnW. Voepel began covering women’s basketball in 1984, and has been with ESPN since 1996.

In April, Aliyah Boston became the Indiana Fever’s first No. 1 draft pick. Monday, she was named the franchise’s second WNBA Rookie of the Year.

She is the fifth player to win the honor unanimously, joining A’ja Wilson (2018), Elena Delle Donne (2013), Tina Charles (2010) and Candace Parker (2008). Boston got all 60 votes from a media panel.

She is the third player out of South Carolina to be named the league’s top rookie, along with Wilson and Allisha Gray (2017). Boston was the sixth rookie to be chosen an All-Star starter.

Boston led the WNBA’s all-rookie team, which also included Seattle Storm guard/forward Jordan Horston (from Tennessee), Minnesota Lynx forwards Dorka Juhász (UConn) and Diamond Miller (Maryland), and Washington Mystics guard Li Meng (China).

The Fever’s other Rookie of the Year was Tamika Catchings in 2002. She was drafted No. 3 in 2001 but didn’t play that season due to a knee injury that prematurely ended her college career at Tennessee. Catchings went on to have an outstanding WNBA career for the Fever; they have not made the playoffs since she retired in 2016.

Boston, a 6-foot-5 center/forward, started every game for the 13-27 Fever, averaging 14.5 points, 8.4 rebounds, 2.2 assists, 1.3 steals and 1.3 blocked shots. Her 57.8 shooting percentage from the field made her the first rookie to lead the league in that category for a season. She finished with 11 double-doubles.

“I feel like over games, I was able to adjust, especially playing teams the second or third time around,” Boston said. “I’m very proud of myself because as a rookie coming into this league, it is very hard.”

Under first-year coach Christie Sides, the Fever made progress this season, reaching double-digit wins for just the second time in the past seven years. Boston was a big part of that and of the Fever’s future. They will be a draft lottery team in 2024, too, and have the best odds of getting the No. 1 pick again.

“Thinking about our future as a team, I just think we’re going to grow this franchise,” Boston said. “We’re going to continue to build it up.”

Kellanova bets on snacking as Ozempic, Wegovy take off

The snack aisle is seen during a tour of a new Amazon Go store in the Capitol Hill neighborhood of Seattle, Washington, U.S., on Monday, Feb. 24, 2020.

For more than a century, frosted cornflakes have been the backbone of Kellogg’s business. That changes Monday, when the company will spin off its stable cereal business in favor of its faster-growing snack unit and rename itself Kellanova.

The spinoff comes weeks after another wager that consumers will graze between meals, when J.M. Smucker bought Twinkie maker Hostess Brands for $5.6 billion in a bid to expand its snack lineup.

But food companies’ major bets on snacking come as investors fear the looming danger of Big Pharma’s blockbuster obesity and diabetes drugs Wegovy and Ozempic. Many investors have high hopes for the pharmaceuticals’ future, but their success could mean slower sales for the companies that produce Oreos, Doritos and Hershey’s Kisses.

Big Food’s bet on snacking began roughly a decade ago, and it’s only accelerated as the rest of the grocery aisles see sales stagnate, particularly as prices rise. The U.S. market for savory snacks is expected to grow 6% annually from 2022 through 2027, and sweet snacks’ sales are expected to rise 4.6% annually during that time, according to HSBC. Roughly three-quarters of consumers plan to snack every day, according to Accenture data.

Millennials and Generation Z consumers are fueling the trend. Younger generations snack more often than older consumers, said Kelsey Olsen, food and drink analyst for market research firm Mintel. Millennials and Gen-Z consumers tend to eat smaller meals that are closer together, creating more occasions to grab a snack.

At the same time, Novo Nordisk’s Ozempic and Wegovy have taken off, fueled by prescriptions to help patients lose weight. The drugs, known as GLP-1 agonists, suppress appetites by mimicking a gut hormone. Some patients even report developing aversions to foods with higher sugar and fat content — a category that includes many big snack brands.

More than 9 million prescriptions for these kinds of drugs were written in the U.S. in the fourth quarter of 2022, according to a Trilliant Health report.

Morgan Stanley estimates that the number of patients taking GLP-1 drugs could reach 24 million, or nearly 7% of the U.S. population, by 2035.

If so, consumption of baked goods and salty snacks could fall 3% — or even more if the new eating habits of the people using the treatments extend to their broader households and friends, according to Morgan Stanley’s research. That puts companies like Hershey, Mondelez, PepsiCo, General Mills and Kellogg’s successor Kellanova at risk.

But not everyone in the industry agrees with that assessment.

Weight loss drug uptake could be slow

Boxes of Ozempic, a semaglutide injection drug used for treating type 2 diabetes and made by Novo Nordisk, is seen at a Rock Canyon Pharmacy in Provo, Utah, May 29, 2023.

After buying Hostess Brands, Smucker CEO Mark Smucker defended the future of Twinkies and Ding Dongs against the threat of GLP-1 drugs.

“There are multiple ways that consumers will continue to snack. … And given that consumers are going to continue to seek all different types of snacks, and sweet snacks are going to continue to be on the radar, we view that our projections here are sound,” he told analysts on a conference call.

For one, GLP-1 drugs like Wegovy and Ozempic are expensive, with a list price of roughly $1,000 a month. That high price has led some insurers to decide not to cover the treatments.

While some of the nation’s largest insurers, like CVS’s Aetna, cover prescriptions of these drugs, the federal Medicare program, many state Medicaid programs and some commercial insurers don’t, leaving patients to pick up the bills themselves.

Another factor could work in the favor of snack sales. Many of the consumers who eat the most junk food likely won’t be able to afford Wegovy or Ozempic.

“Consumption of indulgent salty snacks that would be considered ‘junk food’ generally over-indexes toward lower-income individuals, who are unlikely to be these drugs’ primary users, ” RBC analyst Nik Modi said in a research note Tuesday.

Modi wrote that he doesn’t believe the drugs will ultimately be problematic for the manufacturers of salty snacks.

What’s more, patients have to inject themselves once a week, and if they stop taking the treatments, their effects disappear, usually erasing any weight loss that had occurred over time.

“This sort of drug is super interesting in what it can do, but I think until it comes in a radically different formulation, in a pill or something like that, and something that has enduring impact and obviously the much lower price point, I think it’s going to be tricky,” said Oliver Wright, senior managing director of Accenture’s consumer goods and services unit.

Even if the drugs become more affordable and are more widely adopted, the change won’t happen overnight. Food companies will have time to adjust to shifting consumer behavior.

“We acknowledge that the impact in the near term is likely to be limited given drug adoption will grow gradually over time, but we could see a longer-term impact as drug prevalence increases,” Morgan Stanley’s Paula Kaufman wrote in a note to clients. “Moreover, we expect companies to adapt to changes in consumer behavior through innovation and portfolio reshaping efforts.”

That may mean slower sales growth than expected and moves to divest some brands. But Big Food has been making strides toward healthier options anyway. GLP-1 drugs could just put more pressure on companies to update their portfolios.

PepsiCo and Mondelez are among the companies that have snapped up smaller brands that make healthier snacks. Still, growing them into global powerhouses will take time.

Food companies are also looking internally, investing in their research and development teams to create new formulations that mirror the taste of their full-sugar and salt versions.

“My prediction is, before the end of the decade, we will have a healthy Oreo that can be put on a plate with an old one, and consumers won’t be able to tell them apart — and that will be a good thing,” Accenture’s Wright said.

Taylor Swift Brings Squad Alongside to Cheer on Travis Kelce at NFL Recreation

The princess has returned to cheer on her prince—and she brought along her squad.

While it not confirmed that Taylor Swift and Travis Kelce have begun a love story, the “Blank Space” singer made her second appearance at one of the Kansas City Chiefs star tight end’s football games. On Oct. 1, the pop star arrived at Metlife Stadium in New Jersey to watch the athlete and his team take on the New York Jets.

The singer was accompanied by several of her celeb friends, including Sophie TurnerSabrina CarpenterBlake Lively and husband Ryan Reynolds, his mock frenemy Hugh Jackman and Queer Eye’s Antoni Porowski, as well as her brother Austin Swift. Taylor wore a black long-sleeve top, a matching jacket, denim shorts and black knee-high boots.

The group watched the game from a luxury suite. The “Wildest Dreams” singer was later joined by Chiefs quarterback Patrick Mahomes‘ wife Brittany Mahomes—who had met Taylor and her friends for dinner the night before, as well as Travis’ mom, Donna Kelce. The two were seen hugging and chatting.

41% of French inhabitants favors limiting EVERYONE to ONLY Four airplane flights of their ENTIRE LIFE to ‘struggle in opposition to world warming’ • Watts Up With That?

From CLIMATE DEPOT

Consumer Science & Analytics (CSA): (Via Google translate) Engineer Jean-Marc Jancovici, an expert on climate change, once again called for drastically limiting plane travel, and declared the need to establish a quota of 4 flights per person in a lifetime…

HERE study: The French and the proposal for a quota of 4 flights per person in a lifetime

A CSA & HERE study

41% OF FRENCH IN FAVOR OF THE PROPOSAL OF A QUOTA OF 4 FLIGHTS PER PERSON IN A LIFETIME, ADVANCED BY ENGINEER JEAN-MARC JANCOVICI

On May 30, engineer Jean-Marc Jancovici, an expert on climate change, once again called for drastically limiting plane travel, and declared the need to establish a quota of 4 flights per person in a lifetime. Numerous reactions followed, for and against this proposal.

While the carbon footprint of the aviation sector is regularly singled out in the fight against global warming, and the reduction in the use of aircraft is often cited as one of the measures having the greatest impact on on an individual scale, HERE and the CSA Institute wanted to take stock of the French’s relationship with airplanes. They have just carried out a survey among the French on a possible restriction of the use of airplanes to fight against global warming and to anticipate the depletion of resources.

A majority of French people ready to reduce their use of planes

Questioned by the CSA institute, 64% of French people aged 18 and over say they are in favor of reducing their use of airplanes in the medium term for environmental reasons (including 40% completely in favor). This share peaks at 72% if we focus on those under 35, and at 77% of French people taking a plane (17% of French people surveyed do not take a plane).

“  We are certainly declarative, these intentions must pass the test of facts declares Philippine van TICHELEN, General Director of HERE . But these figures show a very clear majority in favor of a reduction in the use of the plane. Ecological awareness is obvious, in a context where natural disasters worsened by global warming (extreme heatwaves, fires, etc.) themselves have repercussions on the vacation plans of the French in Greece and Italy in the very short term… Added to this is also the impact of inflation and the increase in the cost of air travel, which in the medium term is directing the French towards other modes of transport for their travel.  »

In this sense, the proposal by engineer Jean-Marc JANCOVICI to limit each person to 4 plane journeys over a lifetime is rather well received since 41% of French people say they are in favor.
We once again find a higher score among those under 35 (48%).
“While the 18-35 year old period is often a period conducive to discoveries, to first initiatory journeys, this age group turns out to be the quickest to engage in a very reasoned use of the plane: close to the half of them are in favor of JM Jancovici’s proposal, and this rises to 59% of 18-24 year olds , specifies Philippine van TICHELEN. »

Conversely, Ile-de-France residents are less favourable: only 33% (and 43% would not be at all favourable). “A surprising figure, which could be explained by the fact that Ile-de-France residents are more often required to take the plane for their professional trips, and therefore that the remaining share for their personal trips on the quota of 4 flights per life per person would be even more reduced, argues Philippine van TICHELEN. »

The top 4 destinations in case of air flight quotas

If this measure were adopted, the French would mainly turn to 4 countries on 3 different continents: the United States (31%), Canada (14%), Japan (13%) and Australia (11%).

In terms of organization, travelers would spread their 4 flights over a fairly concentrated period of around 5 years for 24% of them, 40% over a period of 10/15 years , and 28% over a period of 20/ 30 years. Logically, those aged 65 and over would organize their flights in a more concentrated manner over 5 years (41%).

This study was conducted by the CSA Institute and carried out online, on July 18, 2023, with a representative sample of 1,010 French people aged 18 and over, constituted using the quota method.

European House Company opens proposal name for lunar mission tech

The European Space Agency (ESA) is enabling tech companies to take part in its Terrae Novae exploration programme, calling for proposals for small missions to the Moon.

Sending the first European astronaut to explore the Moon’s surface stands at the core of the Terrae Novae 2030+ strategy. It further aims to boost Europe’s presence in low-Earth orbit and participate in the first human mission to Mars.

Small lunar missions form a recent addition to the strategy, “focusing on closing technology gaps and expanding our scientific knowledge of both the Moon and Mars,” said Xavier Barbier, ESA engineer, leading the call for ideas.

The call is open to both private companies and consortia including research institutions. According to Barbier, this presents “an excellent opportunity for small and medium-sized companies to increase their role in the field of space exploration.”

Powering the next business revolution

Join the Financial Times & TNW Future of AI Summit on November 15 & 16

The scope of the proposed missions is broad, as long as they focus on exploration and scientific activities. This can range from fly-by satellites and rovers to resource-extraction processes and improved mapping of potential landing sites.

Applicants need to show that their project’s development from kickoff to launch won’t take longer than 4.5 years, with a total cost no higher than €50mn. Ideally, they should also be able to develop their idea from start to finish, and see it through implementation.

The ESA itself will offer access to resources such as the Ariane 6 launcher for piggyback rides, and the Moonlight programme for lunar communications and navigation services.

The call is open until December 14, 2023, and the submitted proposals will be evaluated in early 2024. Potential candidates should be based in states that participate in Terrae Novae with a small to medium contribution. These are Austria, Belgium, Canada, Czechia, Denmark, Estonia, Finland, Greece, Hungary, Ireland, Luxemburg, the Netherlands, Norway, Poland, Portugal, Romania, Slovenia, Spain, Sweden, and Switzerland.

Meanwhile, UK-based companies can now apply to the National Space Innovation Programme’s (NSIP) £34mn kickstarter call, inviting proposals that can accelerate the development of new space technologies, satellite applications, and services.

The call is open until November 13, 2023, and the selected projects will receive a grant ranging between £150,000 and £1mn. They need to be completed within 18 months.

NSIP’s total funding — backed by the UK Space Agency — reaches £65mn and will be split across further calls in 2024 and 2025.

Weight problems tablet information boosts Construction Therapeutics shares

Aykut Karahan | Istock | Getty Images

Shares of Structure Therapeutics rose more than 30% on Friday after the biotech startup’s experimental obesity pill succeeded in a small early-stage trial. 

The once-daily drug helped overweight or obese participants reduce up to 10 pounds of weight on average after four weeks of treatment, according to a release from the company. Structure said it plans to test its pill in two longer midstage trials as a treatment for diabetes and obesity.

Structure’s pill is part of the same class of drugs as Novo Nordisk‘s blockbuster diabetes drug Ozempic and weight loss counterpart Wegovy. 

Those treatments, known as GLP-1s, have soared in popularity this year due to their ability to help patients lose unwanted pounds. GLP-1s mimic a hormone produced in the gut to suppress a person’s appetite. 

Companies like Structure are trying to capitalize on the booming obesity drug industry, which analysts say could be a $100 billion global market by the end of the decade. 

Structure’s pill could potentially compete with oral obesity drugs from Eli Lilly, Novo Nordisk and Pfizer, which are not approved in the U.S. yet. Analysts say the arrival of cheaper, more convenient pill versions of the GLP-1s could increase access for patients and expand the market for obesity drugs.

Pills are easier to manufacture than injections, making them less likely to run into the supply shortages plaguing injectable drugs such as Ozempic, Wegovy and Eli Lilly’s diabetes drug Mounjaro. Pills are also typically cheaper than injections, though it’s unclear if that will be the case with the obesity treatments. 

Wegovy’s list price tops $1,300 per monthly package, and Ozempic’s is about $935. Novo Nordisk has a diabetes pill called Rybelsus, which has the same list price as Ozempic for a monthly package of 30 tablets.

Sources – Raiders rookie QB Aidan O’Connell to begin vs. Chargers

With Jimmy Garoppolo ruled out due to a concussion and not making the trip to Los Angeles, the Raiders have decided to start rookie quarterback Aidan O’Connell against the Chargers on Sunday, league sources told ESPN.

The Raiders are opting to go with O’Connell, a fourth-round draft selection, over veteran Brian Hoyer, who last won a start in October 2016. The two quarterbacks both received reps during practice last week while Garoppolo was in the concussion protocol, but O’Connell got the majority — if not all — of the reps at practice by the end of the week, according to sources.

O’Connell will make his first NFL start and attempt the first passes of his pro career in an AFC West divisional showdown at SoFi Stadium against a Chargers defense that enters Sunday giving up an average of over 450 yards per game through the first three games of this season.

O’Connell was a preseason standout this summer, drawing comparisons from some NFL scouts and executives to Brock Purdy, another late-round pick who got the opportunity to start last season for the San Francisco 49ers.

In three preseason games in August, O’Connell completed 43-of-62 passes (69.4%) for 482 yards and three touchdowns without an interception. He left some Raiders fans wondering why he wasn’t the backup quarterback to open the season, when Las Vegas listed Hoyer as the No. 2 quarterback.

O’Connell also shined during his college career at Purdue, where he passed for 9,219 yards and 65 touchdowns.

“I think the preseason was valuable for me at the time, just to get out there and play and get it under my belt,” O’Connell told ESPN on Friday. “But I think at this point it’s pretty far gone and it’s different teams and different schemes and different game plans for us. So I’m happy it happened, but it’s time to move on, I think, and see what happens.”

The Raiders signed Garoppolo to a three-year, $72.75 million free agent contract this offseason to replace nine-year starter Derek Carr, even as Garoppolo needed surgery on his left foot after coming to terms with Las Vegas.

Garoppolo, who suffered the concussion in last Sunday night’s loss to the Pittsburgh Steelers, has missed at least 16 regular-season and playoff games because of injury since 2020.

Let the Robotic Take the Wheel. Autonomous Navigation in Area

Tracking spacecraft as they traverse deep space isn’t easy. So far, it’s been done manually, with operators of NASA’s Deep Space Network, one of the most capable communication arrays for contacting probes on interplanetary journeys, checking data from each spacecraft to determine where it is in the solar system. As more and more spacecraft start to make those harrowing trips between planets, that system will not be scalable. So engineers and orbital mechanics experts are rushing to solve this problem – and now a team from Politecnico di Milano has developed an effective technique that would be familiar to anyone who has seen an autonomous car.  

Visual systems are at the heart of most autonomous vehicles here on Earth, and they are also the heart of the system outlined by Eleonora Andreis and her colleagues. Instead of taking pictures of the surrounding landscape, these visual systems, essentially highly sensitive cameras, take pictures of the light sources surrounding the probe and focus on a specific kind.

Those light sources are known to wander and are also known as planets. Combining their positioning in a visual frame with a precise time calculated on the probe can accurately place where the probe is in the solar system. Importantly, such a calculation can be done with relatively minimal computing power, making it possible to automate the entire process on board, even a Cubesat. 

Fraser discusses how to get around in deep space.

This contrasts with more complicated algorithms, such as those that use pulsars or radio signals from ground stations as their basis for navigation. These require many more images (or radio signals) in order to calculate an exact position, thereby requiring more computing power that can reasonably be put onto a Cubesat at their current levels of development.

Using planets to navigate isn’t as simple as it sounds, though, and the recent paper describing this technique points out the different tasks that any such algorithm has to accomplish. Capturing the image is just the start – figuring out what planets are in the image, and therefore, which would be the most useful for navigation, would be the next step. Using that information to calculate trajectories and speeds is up next and requires an excellent orbital mechanics algorithm. 

After calculating the current position, trajectory, and speed, the probe must make any course adjustments to ensure it stays on the right track. On Cubesats, this can be as simple as firing off some thrusters. Still, any significant difference between the expected and actual thrust output can result in significant discrepancies in the probe’s eventual location.

To calculate those discrepancies and any other problems that might arise as part of this autonomous control system, the team in Milan implemented a model of how the algorithm would work on a flight from Earth to Mars. Using just the visual-based autonomous navigation system, their model probe calculated its location within 2000 km and its speed to within .5 km/s at the end of its journey. Not bad for a total trip of around 225 million kilometers. 

However, implementing a solution in silicon is one thing – implementing it on an actual Cubesate deep space probe is another. The research that resulted in the algorithm is part of an ongoing European Research Council funding program, so there is a chance that the team could receive additional funding to implement their algorithm in hardware. For now, though, it is unclear what the next steps are for the algorithm are. Maybe an enterprising Cubesat designer somewhere can pick it up and run with it – or better yet, let it run itself.
