Self-sailing Mayflower ship to have another crack at Atlantic crossing next year

Big Blue to return to the big blue waves

The Mayflower, the crewless, autonomous ship built with the help of IBM, will try to sail across the Atlantic again next year, after its first attempt failed shortly after it left the UK for the US.

Created by maritime non-profit Promare, the vessel was designed to not only steer itself but also collect data for scientists to study all sorts of stuff from microplastics to whales. The Mayflower was designed to operate autonomously; it has a mixture of cameras, radar sensors, and machine learning software to detect objects in its environment and navigate safely around cargo ships and fishing vessels. It also has GPS to stay on course, and runs on solar power with a diesel generator for getting through rough conditions.

In June, three days into an attempt to sail over 3,000 miles from Plymouth in the UK to its counterpart port Plymouth in Massachusetts, it suddenly malfunctioned, and was brought back to British shores for some engineering attention.

A real-time camera feed onboard the Mayflower was shut down; the breakdown was blamed on a mechanical issue that couldn’t be patched with software. After trying to figure out what went wrong, engineers discovered a metal component of the ship’s generator had fractured.

The mishap caused diesel fuel to leak from the equipment, preventing it from working properly. Without this essential power source, the Mayflower was totally reliant on its solar panels and its speed dropped. Mission control directed the ship to limp back to base. The ship is now at sea again to resume data collection, though it isn’t straying too far away from human support while its software and hardware onboard continues to be tested.

"A coupling component of the hybrid drive system developed a leak," Promare's president, Ayse Atauz Phaneuf, told The Reg. "We previously used a commercially available component, but now we have replaced this with one that we designed and manufactured, so it is purpose built, and will not have the same issue."

“On 7 September 2021, Mayflower Autonomous Ship (MAS) was re-launched to resume its testing and scientific research schedule,” according to a statement on the mission’s official website.

“Science teams associated with the equipment installed on MAS will continue collecting and analysing data in order to establish the methodology of using autonomous platforms for oceanographic surveys and research...Camera and data feeds will be turned back on for the cruises along the UK coast planned for Autumn and Winter. The next attempt for the Atlantic Crossing is planned for Spring 2022.”

The Register has asked IBM for further comment. ®

  • Cheers ransomware hits VMware ESXi systems
    Now we can say extortionware has jumped the shark

    Another ransomware strain is targeting VMware ESXi servers, which have been the focus of extortionists and other miscreants in recent months.

    ESXi, a bare-metal hypervisor used by a broad range of organizations throughout the world, has become the target of such ransomware families as LockBit, Hive, and RansomEXX. The ubiquitous use of the technology, and the size of some companies that use it has made it an efficient way for crooks to infect large numbers of virtualized systems and connected devices and equipment, according to researchers with Trend Micro.

    "ESXi is widely used in enterprise settings for server virtualization," Trend Micro noted in a write-up this week. "It is therefore a popular target for ransomware attacks … Compromising ESXi servers has been a scheme used by some notorious cybercriminal groups because it is a means to swiftly spread the ransomware to many devices."

  • Twitter founder Dorsey beats hasty retweet from the board
    As shareholders sue the social network amid Elon Musk's takeover scramble

    Twitter has officially entered the post-Dorsey age: its founder and two-time CEO's board term expired Wednesday, marking the first time the social media company hasn't had him around in some capacity.

    Jack Dorsey announced his resignation as Twitter chief exec in November 2021, and passed the baton to Parag Agrawal while remaining on the board. Now that board term has ended, and Dorsey has stepped down as expected. Agrawal has taken Dorsey's board seat; Salesforce co-CEO Bret Taylor has assumed the role of Twitter's board chair. 

    In his resignation announcement, Dorsey – who co-founded and is CEO of Block (formerly Square) – said having founders leading the companies they created can be severely limiting for an organization and can serve as a single point of failure. "I believe it's critical a company can stand on its own, free of its founder's influence or direction," Dorsey said. He didn't respond to a request for further comment today.

  • Snowflake stock drops as some top customers cut usage
    You might say its valuation is melting away

    IPO darling Snowflake's share price took a beating in an already bearish market for tech stocks after filing weaker than expected financial guidance amid a slowdown in orders from some of its largest customers.

    For its first quarter of fiscal 2023, ended April 30, Snowflake's revenue grew 85 percent year-on-year to $422.4 million. The company made an operating loss of $188.8 million, albeit down from $205.6 million a year ago.

    Although surpassing revenue expectations, the cloud-based data warehousing business saw its valuation tumble 16 percent in extended trading on Wednesday. Its stock price dived from $133 apiece to $117 in after-hours trading, and today is cruising back at $127. That stumble arrived amid a general tech stock sell-off some observers said was overdue.

  • Amazon investors nuke proposed ethics overhaul and say yes to $212m CEO pay
    Workplace safety, labor organizing, sustainability and, um, wage 'fairness' all struck down in vote

    Amazon CEO Andy Jassy's first shareholder meeting was a rousing success for Amazon leadership and Jassy's bank account. But for activist investors intent on making Amazon more open and transparent, it was nothing short of a disaster.

    While actual voting results haven't been released yet, Amazon general counsel David Zapolsky told Reuters that stock owners voted down fifteen shareholder resolutions addressing topics including workplace safety, labor organizing, sustainability, and pay fairness. Amazon's board recommended voting no on all of the proposals.

    Jassy and the board scored additional victories in the form of shareholder approval for board appointments, executive compensation and a 20-for-1 stock split. Jassy's executive compensation package, which is tied to Amazon stock price and mostly delivered as stock awards over a multi-year period, was $212 million in 2021.

  • Confirmed: Broadcom, VMware agree to $61b merger
    Unless anyone out there can make a better offer. Oh, Elon?

    Broadcom has confirmed it intends to acquire VMware in a deal that looks set to be worth $61 billion, if it goes ahead: the agreement provides for a “go-shop” provision under which the virtualization giant may solicit alternative offers.

    Rumors of the proposed merger emerged earlier this week, amid much speculation, but neither of the companies was prepared to comment on the deal before today, when it was disclosed that the boards of directors of both organizations have unanimously approved the agreement.

    Michael Dell and Silver Lake investors, which own just over half of the outstanding shares in VMware between both, have apparently signed support agreements to vote in favor of the transaction, so long as the VMware board continues to recommend the proposed transaction with chip designer Broadcom.
