Perseverance lands safely on Mars and sends back its first images of the surface

Published

on

Mars rover Perseverance has landed on the surface of Mars after a white-knuckle descent involving picking a landing spot just moments before making a rocket-powered sky crane landing. The rover immediately sent back its first image of Jezero crater, which it will be exploring over the course of its mission.

A clearly tense but optimistic team watched as Perseverance made its final approach to Mars a few hours ago, confirming it was on track to hit the bullseye of Jezero Crater, the ancient delta where the rover will soon be roving.

Except for a few brief but expected communications blackouts caused by the superheated air around the craft as it entered the thin Martian atmosphere, the lander sent back a continuous stream of updates to the team on Earth — considerably delayed, of course, by the distance to the other planet.

The team, and charmingly the on-screen hosts at mission HQ audibly gasped, whispered “yes!” and made other signs of their excitement as news trickled in that atmosphere entry had occurred on time, that the craft hadn’t broken up during the ten-G braking maneuver, that the parachute had deployed, that a landing site was found by the ground-facing radar, that the powered descent and sky crane had commenced, and at last finally that the rover had safely touched down on the surface.

Cheering but, in accordance with COVID-19 precautions not (as they normally would) hugging each other, the team celebrated the landing and soon were treated to the first images sent back from the rover.

These initial pictures are low-quality ones sent just seconds after landing by the “hazard camera,” a fisheye used for navigation. As the dust settles (literally) and the rover initiates its more powerful devices and cameras, we’ll have new, color images — probably within an hour or two.

For a more complete look at the mission and its remarkable landing method, you can read yesterday’s profile of the Perseverance mission. The next few days will probably be less exciting than the terror-inducing landing, but soon the rover will be up and running around Jezero, looking for evidence of life on Mars and testing technology that could be used by human visitors in the future.

“We’re not ready to go there with astronauts yet, but the robots are ready,” said JPL director Michael Watkins on the broadcast. “We start by sending, you know, our eyes and arms there in the form of a robot. It is just fantastic to be able to do that, and to learn from each rover, learn from the science and the engineering, and make the next one better, and make more and more discoveries. Every time we do one of these missions, we make fabulous discoveries — and you know, each one is more exciting than the last.”

The exciting thing everyone is looking forward to, Mars helicopter Ingenuity, will hopefully take flight soon as well.

“We have a series of major milestones between now and the first flight. Tomorrow, we’ll turn on the helicopter, and the space station could confirm its health. The next major milestone will be when the rover deploys the helicopter on the surface, and that marks the first moment that Ingenuity operates on its own in a standalone manner, said MiMi Aung, project manager and engineering lead for Ingenuity. “Surviving that first cold frigid night of Mars will be a major milestone, then we’ll execute a series of checkouts, and then we will perform that very important first flight. And if the first flight is successful, we have up to four more flights in the thirty Martian days that we have set aside for our flight experiments.”

The helicopter project will definitely be novel, but it’s not just about recording a first for the sake of NASA being able to say they did it; Ingenuity will hopefully lay a firm technical foundation for future exploration.

“A helicopter flying far ahead of rovers and astronauts in the future can provide high=definition reconnaissance information for the rovers and the astronauts before they take long journeys,” Aung said. “And as importantly, being able to fly will enable us to get to places that we cannot get to with rovers and astronauts, like sides of steep cliffs, deep inside crevices, all areas of high scientific interest. It will be game changing.”

Snowflake latest enterprise company to feel Wall Street’s wrath after good quarter

Published

on

Snowflake reported earnings this week, and the results look strong with revenue more than doubling year-over-year.

However, while the company’s fourth quarter revenue rose 117% to $190.5 million, it apparently wasn’t good enough for investors, who have sent the company’s stock tumbling since it reported Wednesday after the bell.

It was similar to the reaction that Salesforce received from Wall Street last week after it announced a positive earnings report. Snowflake’s stock closed down around 4% today, a recovery compared to its midday lows when it was off nearly 12%.

Why the declines? Wall Street’s reaction to earnings can lean more on what a company will do next more than its most recent results. But Snowflake’s guidance for its current quarter appeared strong as well, with a predicted $195 million to $200 million in revenue, numbers in line with analysts’ expectations.

Sounds good, right? Apparently being in line with analyst expectations isn’t good enough for investors for certain companies. You see, it didn’t exceed the stated expectations, so the results must be bad. I am not sure how meeting expectations is as good as a miss, but there you are.

It’s worth noting of course that tech stocks have taken a beating so far in 2021. And as my colleague Alex Wilhelm reported this morning, that trend only got worse this week. Consider that the tech-heavy Nasdaq is down 11.4% from its 52-week high, so perhaps investors are flogging everyone and Snowflake is merely caught up in the punishment.

Snowflake CEO Frank Slootman pointed out in the earnings call this week that Snowflake is well positioned, something proven by the fact that his company has removed the data limitations of on-prem infrastructure. The beauty of the cloud is limitless resources, and that forces the company to help customers manage consumption instead of usage, an evolution that works in Snowflake’s favor.

“The big change in paradigm is that historically in on-premise data centers, people have to manage capacity. And now they don’t manage capacity anymore, but they need to manage consumption. And that’s a new thing for — not for everybody but for most people — and people that are in the public cloud. I have gotten used to the notion of consumption obviously because it applies equally to the infrastructure clouds,” Slootman said in the earnings call.

Snowflake has to manage expectations, something that translated into a dozen customers paying $5 million or more per month to Snowflake. That’s a nice chunk of change by any measure. It’s also clear that while there is a clear tilt toward the cloud, the amount of data that has been moved there is still a small percentage of overall enterprise workloads, meaning there is lots of growth opportunity for Snowflake.

What’s more, Snowflake executives pointed out that there is a significant ramp up time for customers as they shift data into the Snowflake data lake, but before they push the consumption button. That means that as long as customers continue to move data onto Snowflake’s platform, they will pay more over time, even if it will take time for new clients to get started.

So why is Snowflake’s quarterly percentage growth not expanding? Well, as a company gets to the size of Snowflake, it gets harder to maintain those gaudy percentage growth numbers as the law of large numbers begins to kick in.

I’m not here to tell Wall Street investors how to do their job, anymore than I would expect them to tell me how to do mine. But when you look at the company’s overall financial picture, the amount of untapped cloud potential and the nature of Snowflake’s approach to billing, it’s hard not to be positive about this company’s outlook, regardless of the reaction of investors in the short term.

A first look at Coursera’s S-1 filing

Published

on

After TechCrunch broke the news yesterday that Coursera was planning to file its S-1 today, the edtech company officially dropped the document Friday evening.

Coursera was last valued at $2.4 billion by the private markets, when it most recently raised a Series F round in October 2020 that was worth $130 million.

Coursera’s S-1 filing offers a glimpse into the finances of how an edtech company, accelerated by the pandemic, performed over the past year. It paints a picture of growth, albeit one that came at steep expense.

Revenue

In 2020, Coursera saw $293.5 million in revenue. That’s a roughly 59% increase from the year prior when the company recorded $184.4 million in top line. During that same period, Coursera posted a net loss of nearly $67 million, up 46% from the previous year’s $46.7 million net deficit.

Notably the company had roughly the same noncash, share-based compensation expenses in both years. Even if we allow the company to judge its profitability on an adjusted EBITDA basis, Coursera’s losses still rose from 2019 to 2020, expanding from $26.9 million to $39.8 million.

To understand the difference between net losses and adjusted losses it’s worth unpacking the EBITDA acronym. Standing for “earnings before interest, taxes, depreciation and amortization,” EBITDA strips out some nonoperating costs to give investors a possible better picture of the continuing health of a business, without getting caught up in accounting nuance. Adjusted EBITDA takes the concept one step further, also removing the noncash cost of share-based compensation, and in an even more cheeky move, in this case also deducts “payroll tax expense related to stock-based activities” as well.

For our purposes, even when we grade Coursera’s profitability on a very polite curve it still winds up generating stiff losses. Indeed, the company’s adjusted EBITDA as a percentage of revenue — a way of determining profitability in contrast to revenue — barely improved from a 2019 result of -15% to -14% in 2020.

The owner of Anki’s assets plans to relaunch Cozmo and Vector this year

Published

on

Good robots don’t die — they just have their assets sold off to the highest bidder. Digital Dream Labs was there to sweep up IP in the wake of Anki’s premature implosion, back in 2019. The Pittsburgh-based edtech company had initially planned to relaunch Vector and Cozmo at some point in 2020, launching a Kickstarter campaign in March of last year.

The company eventually raised $1.8 million on the crowdfunding site, and today announced plans to deliver on the overdue relaunch, courtesy of a new distributor.

“There is a tremendous demand for these robots,” CEO Jacob Hanchar said in a release. “This partnership will complement the work our teams are already doing to relaunch these products and will ensure that Cozmo and Vector are on shelves for the holidays.”

I don’t doubt that a lot of folks are looking to get their hands on the robots. Cozmo, in particular, was well-received, and sold reasonably well — but ultimately (and in spite of a lot of funding), the company couldn’t avoid the fate that’s befallen many a robotics startup.

It will be fascinating to see how these machines look when they’re reintroduced. Anki invested tremendous resources into bringing them to life, including the hiring of ex-Pixar and DreamWorks staff to make the robots more lifelike. A lot of thought went into giving the robots a distinct personality, whereas, for instance, Vector’s new owners are making the robot open-source. Cozmo, meanwhile, will have programmable functionality through the company’s app.

It could certainly be an interesting play for the STEM market that companies like Sphero are approaching. It has become a fairly crowded space, but at least Anki’s new owners are building on top of a solid foundation, with the fascinating and emotionally complex toy robots their predecessors created.
