SpaceX launches SuperDracos without anomalies, ISS asters launch iFixit into orbit, and Buran turns 31.



Overview Last week SpaceX proved that Crew Dragon's abortion motors could work, ISS nuts went into EVA to fix their particle physics detector, and Search for Skylab get a directorial job.

SpaceX launches Crew Dragon abortions, nothing explodes

SpaceX successfully completes a static static fire test of engines designed to detonate a Crew Dragon capsule in an interruption scenario.

During an attempt for a similar test in April, the only Crew Dragon capsule to reach the International Space Station (ISS), was blown to the ground. No one was aboard or injured by what SpaceX and NASA delicately called an "anomaly."

Last week's test in the SpaceX 1 landing area of ​​Cape Canaveral Air Station gave Draco the tubes commonly used to orbit maneuver. These engines are also used to refocus the capsule during abortion. Afterwards, a full continuous firing of the eight Crew Dragon SuperDraco engines was carried out.

The April explosion was caused by a surprising "ignition event" of titanium and SpaceX reworked it to prevent recurrence. This time everything went well – because these SuperDracos are needed to get Crew Dragon away from the failed Falcon 9.

SpaceX intends to demonstrate this scenario with a sacrificial Falcon 9 in the months ahead before the first crew to the ISS in 2020 [19659002] "No User-Generated Parts": ISS astros Launches iFixit EVA

We hope the iFixit gang paid much attention to NASA TV last week as NASA astronauts Luca Parmitano and NASA's Andrei Morgan launch an ambitious set of oblique for the repair of the scythe station ic particle detector AMS-02.

The device, which was launched on one of the last space shuttle missions in 2011, fails, but has never had to be repaired into orbit. As such, engineers and astronauts have spent years pondering how to actually deal with machine problems. Simply launching another is not really an option.

Last week in space, the duo took off a roof for debris, pre-placed materials and mounted railings before the next set of EVAs, when things would get even more serious. The next space flight, on November 22, will see "cut the nuts and mark the stainless steel pipes that attach the current cooling system to AMS. A third space path will be required to attach a new block to the side of the instrument before any leakage checks can be performed.

Astronauts have never had to cut and reconnect fluid lines like those during space travel, which adds to the complexity of the procedure. .

The robots are coming. With Rockets

Rocket Lab added a robot called "Rosie" to its production line in an attempt to accelerate the production of its Electron starter.

The company believes that adding an assistant will allow it to increase the frequency of electron production from one every 30 days to one every seven days.

It is far from us to point out that so far the company has not yet managed the launch frequency once a month, let alone once a week, and so we are afraid that soon Rosie may end up with a bunch of backup rockets ready to go.

Those who are afraid of human android armed with launchers need not worry. Rosie includes a 3.5m by 16m five-blade window combined with a custom six-axis rotary axis. The thing is big enough for the machine to be driven the entire first stage. According to the company, you could "park the bus" in this thing.

We think more about Bertha than Arnold Schwarzenegger.

The next Rocket Lab mission, called Running Out Of Fingers, has a launch window that opens on November 25th and will depart from the company's New Zealand launch complex.

Happy Birthday, Buran

While Apollo is grabbing the headlines of the anniversary, it is worth noting that the 31st anniversary of the Soviet Council occupied a winged orbiter, Buran, turned last week.

Started in response to the US Space Shuttle Program, work on the project began in the early 1970s, commencing the construction of orbits (only one of which would fly into space). in 1980. Although visually similar to the US shuttle, Buran relies on the engines of a power booster to send the spacecraft into orbit. Without having to haul three major space shuttle engines (SSMEs) around, Buran would also enjoy greater payload capacity.

If he had flown more than one non-stretched test flight.

After a long series of jet-assisted atmospheric tests, the First Operational Spacecraft was launched on November 15, 1988. The orbit advanced took off two orbits before successfully landing in pilotage. After the money was withdrawn, another flight was withdrawn as well as missions. For all its magic, putting something on Buran was downright expensive compared to the alternatives.

Unfortunately, the flight version of Buran was destroyed when the roof of its hangar Baikonur collapsed. However, the Buran prototype, OK-GLI, can however be viewed in Germany at the excellent Technik Museum Speyer.

Listen Al Shepard Gives Trio Nuts, Dress Up

The makers of an indie movie Search for Skylab tweaked the documentary on America's first space station as they found the audio of an Al Shepherd astronaut boss crew that failed to notify mission control that one of the three, Bill Pogue, had dropped while in orbit.

The Shepard Crew Operational Lock comes in 1 hour and 12 minutes.

Other welcome improvements were made in the quality of some of the film material (except for the 1970s cinemas) and the insertion of some additional content, such as. interview with a farmer from Esperance who monitored the impact of Skylab in 1979.

We looked at the original cut in March and we liked what we saw.

The creator, Dwight Steven-Boniecki, also cut himself a lot from the movie and told us, "For me personally, there are no more moments in the movie where I would like to change it."

Those (like us). who paid cash for this thing on Vimeo during the day will now have an updated version available. Otherwise, the price of a few beers remains the price for anyone interested in a little-forgotten American space history. ®
