Expedition 41 Completes 3 EVAs in October

Astronaut Reid Wiseman prepares to exit the Station for a walk in space, October 7.

In one month, the crew of Expedition 41 aboard the ISS has completed three important EVAs to complete maintenance, science, and preparation goals. On October 7, 2014, astronauts Reid Wiseman (NASA) and Alexander Gerst (European Space Agency) completed a six-plus hour spacewalk that was the first US spacewalk for the year. It was the first spacewalk for both astronauts. Their first task was to move a failed water pump from a temporary holding location and place it in a more permanent spot on the outside of the station. Next, the pair replaced a lighting unit for a camera mounted on the US Destiny space module. Then Wiseman replaced a backup power unit for the mobile remote arm platform which is capable of traveling the length of the station truss. The pair then returned to the station.

During a second American EVA on the 14th, Reid Wiseman and Barry Wilmore exited the station to replace a failed power channel. Their second job was to begin preparations for the long-term reconfiguration of the station. As the new Commercial-built spacecraft come on line, along with the new Orion capsule, the station will have some of its docking ports rearranged to increase the number of spacecraft which can dock with the ISS at the same time. The EVA lasted a bit over 6 hours.

On EVA 40 (third of October and the last one scheduled for 2014), cosmonauts Maksin Suraev (commander) and Alexander Samokutyaev (flight engineer) successfully completed their spacewalk goals a couple of hours ahead of schedule! The first task was to remove the Radiometriya experiment from the exterior (having completed the experiment) and they gently shoved the item off from the station and into space. They next removed the cover from the Expose-R experiment, which tests certain biological samples in space. They then Moved two external communications antennas to a new location for improved performance. Finally they retrieved some samples by the Pirs airlock and returned to the station interior.

Damaged Soyuz carries crew to ISS

Soyuz rocket lifts off from Baikonur.

Reinforcements for Expedition 41 left Earth for a six month stay, blasting off from the Baikonur Cosmodrome on Saturday for a six-hour flight to the ISS. On board Soyuz TMA-14M were Soyuz commander Alexander Samokutyaev, cosmonaut Elena Serova, and NASA astronaut Barry Wilmore.  They will join Expedition 41 Commander Max Suraev (Russia), NASA astronaut Reid Wiseman, and ESA astronaut Alexander Gerst from Germany.

Wilson has flown in space before, on the space shuttle Atlantis on mission STS-129, delivering supplies to the ISS in 2009. Samokutyaev was previously a backup for Expedition 23/24, and served on the ISS on mission 27/28. Serova is the first Russian woman to crew on the ISS, and is on her first flight to the station.

After achieving orbit, and making burns for rendezvous with the ISS, one of the solar panel wing arrays failed to deploy. The right side array was still able to provide enough electrical power for the craft, which docked at the Russian-made Polsk module at a little over 8 pm Mountain time. The slight jarring of the docking maneuver may have been what the jammed panel needed, since it seems it opened on its own a little after docking.

Dragon Cargo Spacecraft Arrives at ISS

View of Dragon on approach to the ISS, just before grappling with the robotic arm.

SpaceX's Dragon cargo spacecraft has arrived at the International Space Station and was caught by the robotic arm just a couple of hours ago at 4:52 a.m. Mountain time. This was the 4th Dragon mission to the ISS by SpaceX. The craft will be docked at the US Harmony module, where astronauts will unload its supplies and experiments and eventually load it with items needing return to NASA engineers on the ground. The Dragon is the only robotic cargo ship that safely returns to the Earth. The US Cygnus, European ATV, and Russian Progress vehicles all terminate their missions by burning up in the atmosphere. Dragon will spend 4 weeks docked to the station before ending its mission. On this trip, besides all the regular supplies of fuel, water, food, and small experiments, the Dragon also brought up an experimental 3D printer that astronauts will use to create certain parts  for maintenance while in orbit.

Space crew returned to Earth

Soyuz TMA-12M departs from the ISS.

Now there's a sign that I've been too busy this last week. I missed setting a post about the departure of TMA-12M from the station! Last Thursday, Expedition 40 commander Steve Swanson, and flight engineers Alexander Skvortsov and Oleg Artemyev safely landed in Kazakhstan. They had left the station under the care of new commander Max Suraev, astronaut Reid Wiseman, and ESA astronaut Alexander Gerst. The new Expedition 41 crew will be joined by three more crewmembers on September 26th.

Duck and Cover! Here Comes Another One!

Omigosh!  It's coming right for us! OK, maybe not.

NASA says it won't hit us. But what if it does? WHAT IF IT DOES!?!?!?

Of course I'm warning you today about Sunday's imminent arrival of asteroid 2014 RC, which will zoom by the planet at about a distance of 22,000 miles. That's close, man! It's so close that it will pass near the orbital zone of our weather satellites and those way-out there communications satellites. 

NASA asteroid plot projection. See http://www.spaceweather.com/

At the time of close approach, the rock will hurtle over New Zealand at 18:18 UTC (universal time). I'll let you do the conversion math to your own time. I'm at Salt Lake City Comic Con, so I have a waiver from having to do any math in my head today. The rock is about 60 feet long, and was only discovered on August 31 by astronomers in Hawaii. So if you feel a big thump on Sunday, maybe the NASA guys were wrong and New Zealand just got smacked. That would be bad, because they make great movies down there.

ISS Summer Summary

It may not be the calendar end to summer, but students all over the USA know good and well that their summer vacation is over and they are heading back to school. And I am finished this year with company business travel, so it's time to get back to commenting on the rubble in space seen from my Space Bunker in Utah. Since my last post at the end of July, what's up with mankind's outpost in Earth Orbit?

Just hours ago, the Cygnus robotic cargo spacecraft burned up in re-entry into the Earth's atmosphere. It's been a busy 6 weeks of comings and goings for Expedition 40 up on the International Space Station. Back in June, both the SpaceX and Orbital launches had been postponed. ANd the new Russian Angara rocket had suffered a launch glitch on the 27th. On July 1st  a launch of a NASA Delta 2 was scrubbed when a problem developed with a sound-suppression system. At least India had success with the launch of a Polar-orbit rocket carrying 5 satellites.

The next day NASA's Delta 2 took off and launched a carbon-dioxide research rocket into space. And the rockets kept on flying. The Russians were next.

The Russians had a series of launches starting with the launch of a light-carrier class Rokot from the Plesestk space center on July 4th. Then on the 9th, a Soyuz rocket lifted off from Baikonur with a weather satellite and a couple other payloads. Finally, the new Angara rocket had a successful launch.

The first flight of the Angara on July 9th from Plesetsk lifted a dummy payload into space to test the rocket systems. The Angara is meant to supplement the Soyuz rocket type launches and relieve the burden of launches only a Soyuz can perform, though it is not man-rated. To show off the demand for the Soyuz rocket, another one was launched on the 10th from the French space Center in French Guiana placing 4 communications satellites into orbit. 

Antares lifts off.

On July 13, Orbital Sciences launched its Antares rocket from its facility on Wallops Island, Virginia to place the Cygnus cargo craft on a path to the ISS. Close behind, SpaceX launched a Falcon rocket placing 6 ORBCOMM satellites into orbit on the 14th. On Wednesday, the Cygnus cargo craft docked with the ISS.

Docking for the Cygnus with help from the CanadArm robotic arm.

Carrying food, oxygen, and supplies from Earth, the Cygnus also delivered 32 micro-satellites which will be released over time by the crew of Expedition 40. The Cygnus was docked by engineers on Earth this time using the robotic arm after astronaut Commander Steve Swanson captured the craft, and secured to the Harmony module of the station. The craft is named SS Janet Voss in commemoration of the astronaut who passed away in 2012.

The launches continued. A Soyuz carried a biological research satellite into space on July 20. On the 22nd, a Russian Progress Robot cargo ship was undocked from the ISS to make a place for an upcoming resupply mission. The Progress ship was then directed to deorbit and crash into the Pacific.

On Wednesday the 23rd, a new Progress craft was launched from Baikonur and arrived at the ISS six hours later. The M-24M carried supplies for the station. Once unloaded, it will eventually be filled with trash and undocked later.

On Monday the 28th, a Delta 4 carried the GSSAP classified secret satellite into orbit. The satellite, though developed in secret, will be used to do research on possible collisions in space and any potential enemy military weapons developments in space.

On Tuesday the 29th, the European Space Agency (ESA) launched the 5th and last of the ATV robot cargo ships to the ISS. It was lifted on the Ariane 5 rocket from the French space center in French Guiana, South America. It was the 60th successful launch of the Ariane 5, a remarkable achievement.

And the rockets kept flying. On August 1st an Atlas 5 blasted off from Cape Canaveral, carrying a GPS navigational satellite. On August 5th SpaceX launched a Falcon 9 rocket carrying the AsiaSat 8. On the same day, the ESA announced a remarkable success: the Rosetta space probe rendezvoused with comet 67P/Churyumov-Gerasimenko. Instead of just passing close by, the probe has matched its speed and direction and will travel with the comet, studying it from close up.

The ATV finally docked with the ISS on Tuesday the 12th. It was berthed at the Russian Zvesda module, and astronauts began unloading the cargo ship. Although it is the last of the ATV series of cargo craft, the technology from this version will be used to design and build the service module for NASA's future Orion spaceship.

China got back into the space scene on August 9th, launching a Long March 4C rocket from the Jiuquan Satellite Launch Center in Gansu Province. It carried a remote-sensing satellite. A few days later on the 12th, another Atlas 5 took off, this time from Vandenberg AFB in California, carrying its own remote-sensing satellite, the WorldView 3.

View from the ISS, Cygnus released from the station, seen just right of center.

And that brings us to the last couple of days. Orbital's CRS-2 mission was over, and the Cygnus craft undocked on Friday. The ground engineers gave the craft remote directions to de-orbit and burn up this morning as it re-entered the atmosphere.

A previous Cygnus craft disintegrates and burns up over the Pacific.

Orbital has 6 more cargo missions under the current contract, and will no doubt receive further contracts in this successful series. And with the morning's fireworks provided by Cygnus, we get back to the business of watching the business of working in space.

50 Years Ago: X-15 Number 2 Rebuilt, Flies Again

X-15 Number 2, on a later test flight using ablative coatings and extra fuel tanks, dropping from a B-52 mothership. NASA photo release.

On June 25, 1964, The second-built X-15 test rocket plane returned to service. The craft had suffered a significant, but not destructive, crash back in November 1962, when it had flipped over on its back after a rough landing on a dry lake bed. On it's return flight, Major Robert Rushworth of the USAF dropped from its B-52 carrier, ignited the engine, and flew to an altitude of 82,000 feet, reaching a speed of Mach 4.49! This aircraft survived the rest of its test flights, and is currently preserved for viewing at the Wright-Patterson AFB National Museum of the United States Air Force in Dayton, Ohio.
