Abort command sent from blockhouse at Baikonur seconds before ignition. Countdown proceeded without any problems until the scrub.

NASA wrapping up coverage. Engineers at Baikonur are still trying to find the problem.

With a 48 hours postponement and a possible two days rendezvous, this could have an impact on U.S. EVA-48...

Progress MS-08 liftoff aborted at the last moment

The planned launch of the Progress MS-08 spacecraft bound to the International Space Station, ISS, was aborted just moments before scheduled liftoff at 11:58 Moscow Time (3:58 a.m. EST) on February 11.
The Automated Engine Cutoff, AVD, command was issued indicating a technical problem with the final automated sequence. The launch vehicle remained safely on the pad. According to Roskosmos, the backup launch date is on February 13.

Anybody wants to translate?

very rough translation: "Regardless how tight the schedule is, that's not a reason to compromise the rules and measures related to safety-at-work procedures"

This is the second time in a row that a last-minute abort followed by a 48-hour turnaround has happened for a Progress mission bound for a 2-orbit rendezvous.
Because the Falcon Heavy Test Flight was successful, it has inspired thousands of people to consider changing the future of space travel.

No urgency of work is the basis for violating the rules and measures of safetyless technology!

Kind of.

Not sure this is the right place for it but the article for this mission has some typos (Most noticeably the use of MS-07 where it should be MS-08).

Also a question: The mentioned deltaV's (e.g.  35.917 m/s for Impulse 3 burn) in the article are quite precise (4 or 5 digits). Can the burns of Progress be timed so precisely to achieve such a control and can one know beforehand how much (to 0.01%) deltaV is needed for the orbit changes? I would assume the exact orbit of the ISS is not known until a few hours before launch due to interactions with the thin atmosphere up there and therefore the burns should vary a bit in length and deltaV.

Cheers,
Shanuson

Also, why does the article call it "record-breaking" when Gemini 11 did it in just one orbit in 1966?

And Cosmos 188 docked with Cosmos 186 67 minutes after the former's launch in 1967: and Cosmos 213 docked with Cosmos 212 47 minutes after the former's launch in 1968.
I've always been crazy but it's kept me from going insane - WJ.

Record breaking to the ISS.
