50 Years Ago: First Woman in Space!

Cosmonaut Valentina Tershkovova

Fifty years ago today, the Soviet Union took another leap forward in launching the first woman into space aboard Vostok 6. Valentina Tereshkova also became the first civilian to fly into space. She also saved her space mission!

Launch of Vostok 6 from Baikonur.

I've read in several accounts that the original mission goal was to have two women in space at the same time in Vostok 5 and 6, making a rendezvous, but that plan changed and instead Valery Bykovsky piloted the previous craft into orbit. Two days after that launch, Tereshkova lifted off in Vostok 6, and she made radio contact with Bykovsky after she reached orbit. Near the beginnings of the flight, Tereshkova made a discovery that there was an error in the descent program which would have caused the craft to ascend in orbit instead of descend. After she informed this to the Russian flight control, the engineers sent up correct instructions to Tereshkova, which she entered into the navigation program, thus saving her from problems during deorbit. This event was kept a secret until 2004.

Keeping contact with Vostok 5 by radio, Tershkova flew within several miles of Bykovsky. Encyclopedia Astronautica has an interesting account by Tereshkova of what her mission was like, including an unfortunate event caused by eating food that was not very good: http://www.astronautix.com/flights/vostok6.htm

After re-entry, according to procedures, Tershkova ejected from the capsule and parachuted to the ground separate from the capsule chutes. They landed nearby each other, but she was stuck on her back in the ejection couch until rescuers reached her by plane and parachuted down to assist.

Vostok 6 was the last mission using the Vostok 3KA spacecraft. The capsule is on display at the RKK Energia Museum in Korolyev.

Two Dockings, Two Stations

The Shenzhou 10 spacecraft completed docking with the Tiangong 1 space station on Thursday afternoon, Beijing time. Although the procedure was run automatically, Mission COntrol on the ground and Pilots in the spacecraft stood ready to intervene in case of malfunction. This success makes the second manned docking of spacecraft for China. China is the third nation after America and Russia to develop their space program to include rendezvous and docking two spaceships.

The docking at the International Space Station was a bit trickier. A busy place at normal times, when Europes largest spacecraft comes calling, you have to make room. A couple of Progress robotic space cargo ships were already docked at the ISS, so Progress 51 was released. The craft had been filled with garbage, waste, and unwanted items to make room for new supplies coming up. Originally, when Progress 51 blasted up into orbit, it had suffered a communications antenna failure and had to rely on backup systems. With the release from the station, engineers will have a few days to work with the system from mission control and try to resolve the problem from the ground. Then they will deorbit the craft to burn up over the ocean.

ATV-4, "Albert Einstein" is the 4th and heaviest spacecraft launched by the European Space Agency. it is carrying 5000+ pounds of cargo, hardware and supplies, plus 1200+ pounds of water and 200+ pounds of atmosphere. It has now docked at the end of the Russian Zvesda module. Once emptied of supplies, it will serve as more room for the astronauts and as storage space. WHen it is time to remove more waste and garbage, it will follow Progress 51 into a deorbit burn.

Currently, only the SpaceX Dragon Cargo ship is capable of returning experiments and valuable items to Earth for study.

50 Years Ago: Vostok 5 begins Joint MIssion

On June 14, 1963 the Soviet Union launched Vostok 5 from Baikonur. This mission was a joint mission similar to Vostok 3 and 4, which made a close approach. Cosmonaut Valery Bykovsky in his spacecraft would attempt a close pass of Vostok 6 which would shortly launch.

As with the other Vostok missions, the cosmonaut was the single occupant of the spacecraft. The Vostok 5 mission was expected to last 8 days. The second spacecraft, Vostok 6 was scheduled for launch on June 16.

Things did not go as planned for the mission.  Increased levels of solar activity presented a radiation danger for anyone staying up for a long time, and there was a problem with the waste collection machinery. No doubt Valery detected a new odor in space. However, being the professional pilot that he was, Valery maintained his flight duties and was finally recalled to return to Earth after 82 orbits. Although shorter than planned, to this day it remains the longest duration flight of a single occupant spacecraft, setting a record and putting America farther behind in the space race.

For his mission, Bykovsky was awarded "Hero of the Soviet Union," Russia's highest honor. He would eventually reach the rank of Major General of the Soviet Air Force. He was later scheduled to fly on the Soyuz 2 mission. Remarkably, after the accident with Soyuz 1, the mission was postponed, and it was discovered that the craft had the same problem as the first one. If he had flown the Soyuz 2 mission before alterations, he would have perished.

Shenzhou 10 Launch Attempts China's Longest Mission Yet

China has set herself on an ambitious schedule of missions. On this, only the fifth manned space mission, Chinese astronauts (sometimes called taikonauts) are attempting a 15-day mission to the Tiangong space module in orbit around the Earth. Unlike ISS, the Tiangong 1 is not permanently manned. It is being used as a temporary way station on a scheduled path for China to build their own space station by the year 2020. The first manned mission to Tiangong 1 was last year. Each mission brings China closer to their stated goals, eventually to reach the Moon.

China has gone from first manned launch to second docking with a space station in just five missions. Their planning has been careful and ambitious. But it shows that countries entering the manned space age on their own no longer need to go through the long and difficult process of scientific progression on their own. America and Russia paid for that discovery during the last 50 years. China just showed other countries that you can buy the technology (as they did from Russia, although some advanced navigational technology was taken from American sources) and develop your own space program. Soon, once the US commercial companies like SpaceX and Boeing complete their own manned rockets to the ISS, a country will merely need to buy a complete rocket and capsule set. Currently, other countries will still need to develop their own space infrastructure (launch bases) of their own of use a previous existing one. However, I believe that we will soon see space construction companies contract out to build launch facilities for other countries.

The Shenzhou 10 mission improves upon the last visit to the station. In addition to bringing supplies, the crew will install a new waste processing facility (think about that- no doubt a welcome addition), the crew will enjoy a greater variety of food for their meals, and an educational lesson will be televised to the students of China. They will practice docking maneuvers, and generally set the stage for the next Chinese manned flight.

On Monday June 3, the Chinese Space Agency CMSE (China Manned Space Engineering) rolled out the Shenzhou 10 to the launch pad. The spacecraft sits atop a Long March 2F rocket and is planned to lift three Taikonauts into space sometime around June 9-11. So really, any time now.

This will be the second Chinese mission to the Tiangong 1 space station, currently orbiting the Earth. The last mission there, Shenzhou 9 in June 2012, took three spacefarers on a short visit to the station and included China's first woman astronaut, or Taikonaut as Chinese space travelers are designated. On that mission, Liu Yang and her fellow crewmembers stayed with the station for 10-11 days.

The Shenzhou 10 mission is expected to attempt a fly-around of the station, followed by a docking and a 12-day (I think) stay before coming back to Earth. According to Space.com, Chinese space agency leaders claim this will be the third in a series of tests for the Agency to master the art of placing a station in space and transferring crew members. The goal is for China to build a larger manned station by 2020.

Another Asteroid Passes close to Earth

Asteroid orbit path comes close to Earth, left of center.

2013 continues to be the Year of the Asteroid Menace. Today a recently-discovered asteroid, 2013 LR6, will approach the Earth's orbit today and pass close by tomorrow. The 50 foot-wide rock will come closer than does the Moon, at about 68,000 miles (the Moon is at about 240,000 miles). That's close in NEO terms (Near Earth Objects). 

Yahoo News has a good article explaining more about this event and a link to watch the approach LIVE: http://news.yahoo.com/asteroid-fly-within-moons-orbit-tomorrow-watch-live-153153909.html

From the SpaceRubble Command Bunker: We often hear that scientists have discovered such-and-such percent of the asteroids that could hit us. Yet rocks such as this one, the recent big one and the Chelyabinsk meteor hit prove that it's the ones you don't see coming that are the true danger to the Earth. And if they aren't seeing all of them, then we really don't have a number we can pin a percentage on, we only have a Wild-a** guess to go on, 'cause who in the heck knows everything that's out there in space!

Einstein goes to the ISS

The European Space Agency (ESA) launched their 4th large cargo spacecraft to the ISS yesterday. The Automated Transfer Vehicle (ATV-4), named after the famous physicist Albert Einstein, blasted off from the Kourou space launch facility in French Guiana carrying supplies for the International space station.  This particular mission is the heaviest that has been launched by the ESA, weighing in at 20+ tons of craft and supplies. The spacecraft will maneuver into a matching orbit with the ISS over the next 10 days, expecting to dock on Saturday June 15. It will remain attached until october, when it will be deorbited with garbage  from the station to burn up in the atmosphere.
