ExoMars team delays 2020 Red Planet road trip after failing to complete all necessary testing

Absolute mad lads


The European Space Agency (ESA) and Roscosmos Space Corporation (RSC) have blinked and postponed the planned 2020 launch of the ExoMars rover Rosalind Franklin.

The mission had been on shaky ground after failures during the testing of the lander's parachutes and despite help from the likes of NASA, the team finally accepted that things would simply not be ready in time to meet the narrow July-August launch window.

Instead, the rover will be sent on its way during a window that extends from July to October in 2022.

Speaking in Paris today, ESA director general Jan Wörner insisted the gang had to be 100 per cent sure (or as near as they could be) that the mission would be a success and, after praising how complete both the Russian and European sides were, admitted that things just weren't going to be ready in time.

ESA also noted that the whole virus furore wasn't helping matters either. The press conference was, after all, supposed to have been in Moscow and RSC boss Dmitry Rogozin, who was supposed to have been in attendance, did not turn up due to "technical issues."

However, it is the fact that testing just isn't going to be completed in time that has put paid to plans for a 2020 launch.

As well as a final two high-altitude parachute tests due in March in the US (and competing with other NASA priorities), the team noted some "technical bugs" in the electronics of the descent module. All solvable, they said, but, alas, not in time to get the flight software finalised, validated and ready for launch.

"We could launch," the DG noted, but after the experience of the agency's previous attempts at landing on the Martian surface (Scaparelli and Beagle 2) the motto is: "Do all the tests before you launch."

As for what happens now, a small fix is required to the solar array of the rover before it begins its lengthy period of clean-room storage.

Bit dusty, innit?

The Register queried the impact of those years of storage on the spacecraft and asked whether there might be any shortening of the lifetime of its components. Francois Spoto, the programme team leader for the project, was unsure. "So far, we don't think so, but there has to be further study."

Wörner added that if it transpired that there was a specific component that turned out to have an issue, then it could be changed.

Of course, two years sitting motionless in storage prior to launch will do the rover's lubricated moving parts no good at all, and Spoto said that it would need to be "awakened" every now and again.

We also asked what the additional costs for the delay would be. David Parker, ESA's director of Human and Robotic Exploration, replied the final figure was "pending negotiations with industry", although the team had highlighted the risk of delay and included a risk mitigation budget in the overall Mars exploration programme.

Delaying a mission to ensure all tests are complete? We could think of one aviation giant that could learn a thing or two from such a revolutionary approach.

Wörner rounded out the press conference with the comment "Stay healthy". We're not entirely sure if he meant the humans listening in or the rover facing an unexpected stay in clean room quarantine. Possibly both. ®

    Puny human brains baffled by K8s complexity, leading to blunder fears

    Kubernetes, despite being widely regarded as an important technology by IT leaders, continues to pose problems for those deploying it. And the problem, apparently, is us.

    The open source container orchestration software, being used or evaluated by 96 per cent of organizations surveyed [PDF] last year by the Cloud Native Computing Foundation, has a reputation for complexity.

    Witness the sarcasm: "Kubernetes is so easy to use that a company devoted solely to troubleshooting issues with it has raised $67 million," quipped Corey Quinn, chief cloud economist at IT consultancy The Duckbill Group, in a Twitter post on Monday referencing investment in a startup called Komodor. And the consequences of the software's complication can be seen in the difficulties reported by those using it.

    Google has quietly dropped its demand that users of its free G Suite legacy edition cough up to continue enjoying custom email domains and cloudy productivity tools.

    This story starts in 2006 with the launch of “Google Apps for Your Domain”, a bundle of services that included email, a calendar, Google Talk, and a website building tool. Beta users were offered the service at no cost, complete with the ability to use a custom domain if users let Google handle their MX record.

    The service evolved over the years and added more services, and in 2020 Google rebranded its online productivity offering as “Workspace”. Beta users got most of the updated offerings at no cost.
