Alexander Skvortsov, Mikhail Kornienko, Tracy Caldwell Dyson Returned to the Earth

25.09.2010


Soyuz TMA-18 descent capsule with the crew – Alexander Skvortsov, Mikhail Kornienko, Tracy Caldwell Dyson - this morning, landed successfully 35 km away from Kazakh’s Arkalyk at 9:23 (05:23 GMT).

The Soyuz departed from the International Space Station at 6.02.12 MSK. 
Health status of the crew is fine. All descent operations were nominal.
Skvortsov, Kornienko and Caldwell Dyson spent 176 days aboard the ISS. They received 3 Progresses and 2 shuttles, integrated new Russian module Rassvet with the station’s Russian segment. Kornienko and his colleague Fiodor Yurchikhin made one space walk.

In the ISS, the crew of expedition 25 continues its operations. Soyuz TMA-01M to fly from Baikonur on Oct. 8 will bring three new crew members to ISS-25 commander Douglas Wheelock, flight engineers Fiodor Yurchikhin and Shannon Walker.

That's not what I'm being told. DM cabin pressure issues have been raised. Let's all rattle our contacts about this.

Also, note "Космонавтов задержала на МКС собственная неаккуратность и болтик -- Аппарат корабля "Союз ТМА-18" со второй попытки прилетел на Землю."
http://www.gzt.ru/topnews/science/-kosmonavtov-zaderzhala-na-mks-sobstvennaya-/326707.html

...where Perminov blames the bolt break and consequent false pressure signal on the carelessness of the cosmonauts -- that would be Yurchikhin.

He used an old Russian proverb, "When you have enough muscles who needs brains?" to mock what he characterized as the cosmonaut approach.

This, after only a few hours of investigation. It stinks.

I don't ever seem to recall a NASA (Soyuz) crew member leaving for Houston so soon after landing.
Haven't previous NASA astronauts spent about 1 to 2 weeks in Russia before flying back home?
Thank you.

Thanks to GoforTLI for the excellent coverage.

Seconded. Thanks to everyone. Glad they made it safely to the ground.
Remembering those who made the ultimate sacrifice for our rights & freedoms, and for those injured, visible or otherwise, in that fight.

I belive TJ Creamer also flew back to Houston right after landing. (he was the first to do so)

Yep, it's called a direct return, and it was first done on TMA-17.

Have there been DM pressure issues before ?

Yes.

Regarding blaming the cosmonauts, too, it's happened before:

Blaming the Cosmonauts is practically SOP for TsuP. If they don't blame them, they turn to NASA, and after blowing smoke in those directions as long as possible, they grumble out an admission of a "technical fault" or something along those lines.

From ISS On-Orbit Status Report for 25/09/2010:

Yest posadka! (We have Landing!) Welcome back home, Tracy, Alex and Mikhail! After 177 days 1 hour 19 minutes in space (175 days 23 hours 58 minutes docked to ISS), Soyuz TMA-18/22S, carrying Exp. 24 crewmembers Alexander Skvortsov (Russia), Mikhail Kornienko (Russia) and Tracy Caldwell-Dyson (USA), landed successfully at 5:23 AM GMT this morning (local time: 11:23 AM) in central Kazakhstan near the city of Arkalyk (51.01°N, 66.57°E). The crew was in excellent condition. [TMA-18 (#228) undocked from MRM-2 last night at 2:02 AM GMT, after the crew had performed leak checks of the vestibule area between MRM-2 and the Soyuz, of their Sokol suits and of the hatch between the Descent Module (SA) and Orbital Module (BO). Three minutes after physical undocking, Soyuz performed a 15 second separation burn. The actual de-orbit burn of 4 minutes 17 seconds duration came at 4:31:17 AM GMT, resulting in a 115.2 m/s deceleration. Tri-module separation occurred at 4:56:10 AM GMT. 16 seconds after the separation command, software pitched the Instrumentation/Propulsion Module (PAO) in the rear to a specific angle (-78.5° from reference axis) which, if the PAO would have remained connected to the SA, would have resulted in enough heating on the connecting truss to melt it, thus ensuring separation. Atmospheric entry followed at 4:59:12 AM GMT and nominal parachute deployment at 5:07:42 AM GMT. Following initial observation by Russian SAR (Search And Recovery) personnel, the Soyuz vehicle landed at 5:23 AM GMT. The crew was flown by helicopter to Karaganda where Tracy boarded the waiting NASA Gulfstream-III airplane which today is bringing the crewmember back to Houston (with 2 refueling stops) - the second direct return for USOS crewmembers. Alexander & Mikhail meanwhile were flown on the GCTC (Gagarin Cosmonaut Training Center) Tu-154 back to Chkalovsky airfield of the GCTC at Zvesdniy Gorodok (Star City).]

Tasks currently listed on Doug's & Shannon's "job jar" job roster are:
• MARES (Muscle Atrophy Resistive Exercise System) hardware stowing
  [MARES is currently in need of troubleshooting due to a power issue].

It's a mistake, it should be 176 days, not 177.

I enjoyed the headline on this report of the landing:-


http://www.upi.com/Science_News/2010/09/25/Space-station-astronauts-land-in-China/UPI-78591285423165/

Rather ironic in view of UPI's strapline "100 Years of journalistic excellence" !!

Roscosmos Experts Have Found the Cause of Failed Soyuz Departure.

Roscosmos Head Anatoly Perminov explained the reason for failed Soyuz TMA-18 departure this Friday. According to him, this was a purely mechanical cause, which led to glitches in the software and false signals.
After the interrupted undocking sequence on Sept. 24, Soyuz TMA-18 descent capsule landed safely in Kazakhstan on the next day, Interfax informs.
Roscosmos Head said he appreciated the work done by all experts who supported the departure and landing operations.

Tracy did not stand to receive an honor as opposed to the two Russian cosmonauts. Looked like she was still struggling a bit to get accustomed to the new gravitational effects after spending 176 days in space.
