Russian space agency Roscosmos [1]reported the "temporary" fix on 19 October after the source of the seepage was identified using the drift of a tea bag, [2]according to Russian News Agency, Tass .
The fix was good news for the new Expedition 64 crew, consisting of NASA astronaut Kate Rubins and Roscosmos cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov. The trio [3]arrived at the ISS for a six month stint aboard the outpost after a speedy transit in Soyuz MS-17. The welcoming crew, including commander Chris Cassidy, [4]returned to Earth safely last night.
Rubins could well take the honour of being the last NASA 'naut to require a Soyuz seat as the US commercial crew schedule picks up pace, with SpaceX expected to launch the first operational crew mission some time in November.
The new crew will also welcome another SpaceX vehicle, in the form of the company's 21st commercial resupply services (CRS-21) mission in late November or early December. Notable for being the first flight of the upgraded cargo version of the Dragon, the freighter will also carry [5]the first commercially funded airlock for the ISS, the Nanoracks Bishop Airlock.
Another batch of Starlinks added to the heavens while GPS sulks
SpaceX repeated the never less-than-impressive feat of launching a Falcon 9 and landing its first stage on a droneship on 18 October while the rocket due to launch a GPS satellite remained firmly grounded as investigations continued into the cause of the scrub.
The payload of 60 satellites brought the total launched to date for the constellation to only a few Falcon 9s shy of the 1,000 mark. The launch, from Kennedy Space Center's LC-39A pad, was the sixth flight of that particular booster as well as a reuse for the payload fairing halves.
The company has yet to give an exact date for when it will try again to launch the GPS satellite, with the firing currently likely for November. Instead, it is pressing ahead with the launch of the next batch of Starlink satellites atop another flight-proven Falcon 9, this from Cape Canaveral Air Force Base's SLC-40 in the coming days.
[6]Microsoft will be so pleased .
Rocket Lab keeps focus
Rocket Lab scrubbed the first launch opportunity of its [7]next mission from Pad A of Launch Complex 1 on New Zealand's Mahia Peninsula. The company cited some [8]iffy sensor data as the cause.
The mission's launch window runs from 21 October to 2 November with the next opportuniy kicking off tonight at 22:02 UTC. The Electron is to send 10 small satellites to a 500km circular low Earth orbit.
As well nine SuperDove imaging satellites for Planet, the mission will also carry Canon's telescope-equipped Earth imaging satellite CE-SAT-IIB. Canon's CE-SAT-IB was lost when the "Pics Or It Didn't Happen" mission failed to reach orbit in July.
Dubbed "In Focus", the mission is the fifteenth for the Electron booster and the fifth of 2020 for the small satellite launcher outfit.
Those hoping to see parachutes pop out from the descending first stage are, however, in for disappointment. The company is not planning any recovery testing this time around.
From Pluto to New Mexico
Dr Alan Stern, famed for his work on the New Horizons mission, is to take to suborbital space as the first researcher to conduct NASA-funded science experiments while flying aboard a commercial spacecraft.
The spacecraft in question will be Virgin Galactic's [9]SpaceShipTwo , which will carry Dr Stern on a suborbital mission on a to-be-determined date. Among other work, he will be tasked with operating a former space shuttle camera to determine how well space astronomical observations can be conducted.
Stern, who has been involved in 29 space mission science teams, but never actually been there in person, [10]described the event as "a major career highlight."
Hopefully he will not have too long to wait. SpaceShipTwo has only managed two flights to space; the last being well over a year ago. Since then it has undertaken two test flights from its new home in New Mexico, but passengers hoping to use their ticket to space have been kept waiting.
The [11]company is planning its first flight to space from New Mexico this autumn. ®

Re: Earl grey or english breakfast?
Its nice to see a low cost, low tech solution succeed once again.
Re: Earl grey or english breakfast?
The FOUND the leak with a tea bag, but didn't plug the hole with it.
Re: Earl grey or english breakfast?
I was disappointed by that headline. I read it and thought, well if you leave a teabag in a cup for too long, it does tend to stick to the sides and be hard to remove. Not to mention that time someone put one in the dishwasher at work, and it got stuck in the plastic rotating water jet thingymagig. That took a lot of work to get clear - so I can attest that dried teabags can be pretty strong. But I'm not sure I'd trust my life support to one.
For a repair I'd stake my life on I'd use either dried porridge or gaffer tape...
Re: Earl grey or english breakfast?
Hmm dried porridge indeed would give a repair that might survive reentry, I'd suggest dried soft boiled egg yolk as another near eternal repair
Re: Earl grey or english breakfast?
> dried porridge or gaffer tape
You'd want a Soreen Banana loaf for that really. Just the right amount of squish and it never seems to dry out.
Re: Earl grey or english breakfast?
I thnk specifically what you need is anything squidgy or chewable applied liberally by a weaning 6 month old.
Re: Earl grey or english breakfast?
Thanks for the cue! I need one about now!
Re: Earl grey or english breakfast?
Another proof that there's no trouble a tea can't solve.
Tea and [1]duct tape .

Good to hear you stand a chance of getting a decent cuppa on the ISS. It would have been a long way to go if you couldn't. But is it Yorkshire Tea? Earl Grey? Lapsang Souchong?
I doubt you could make a decent cuppa on the ISS. IIUC, while the O2 partial pressure is about Earth normal, the total air pressure is much lower. Meaning that water will boil at below the temperature required to make a good cuppa. They have a similar problem in the Everest base camps.
So they just need a pressurized water boiling device? Doesn't sound that complex. I'll design one for NASA for $5million or so.
Trouble is that to open said pressure device you got to cool it down - then you are back where you started from.
A Nimrod Variation
In 2006 crew of an RAF Nimrod used a teapot to block up a hole when a hatch failed to shut properly. Mitch Benn even wrote a song about it for The Now Show.
Much more importantly, what temperature do they heat the water to on the ISS to make tea? I think Italy provided an espresso machine, but who gave the tea-making facilities?
(I think we can forgive them for using teabags. Loose tea and weightlessness would be a little undesirable.)
Re: A Nimrod Variation
Given the usual state of so called tea in the colonies, one would hope the Russian side has a decent samovar installed with appropriate supplies.
Re: A Nimrod Variation
On operation Black Buck - the first successful attempt to bomb the Falkland Islands runway was nearly aborted because the backup aircraft had a refuelling problem. Earlier, the strike aircraft had been unable to pressurise the cockpit after take-off, because they couldn't close one of the windows.
However, they were determined to make it. So they unwrapped one of the pilot's sandwiches, and blocked the gap with the wrapping. Not sure if it was clingfilm, brown paper bag or tinfoil though. Neither does history record what the sandwich filling was. However I'm pretty certain that there would have been plenty of flasks of tea on board - especially as the cabin heater on a Vulcan apparently took half an hour to get up to temperature - so you were pretty chilly for the first bit of any Vulcan flight. Especially with the windows open.
Re: A Nimrod Variation
Not that I would want to drink too many cups of tea on an aircraft where the only toilet is a bottle ...
tea to taste
Was that the teabag they were planning to brew up, pour out and connect to the infinite improbability drive?
Rocket Report
Is this The Register's version of the Rocket Report (Ars Technica)?
Re: Rocket Report
No, this is the Hot Drink Revue. The rocket stuff is just a side effect.
Another leak?
I seem to remember there being a leak some months back. They've just gotten the idea on how to fix it? Is it rocket science?? No, just spaceship science, right? Now they have a procedure for the next leak!
Re: spaceship science
I'd say this is spaceship technology, which is arguably harder than spaceship science.
Bishop Airlock?
What's his diocese?
'Ow do you tell?
Tattooed on the back of his neck.
Did I miss something?
A section heading says "From Pluto to New Mexico". The New Mexico bit I saw, but what's that about Pluto?
Re: Did I miss something?
