Following a one day delay, due to a wayward plane during the countdown yesterday, Orbital ATK successfully launched their Cygnus spacecraft, S.S. Gene Cernan today for an International Space Station rendezvous on Tuesday.
This was the second Cygnus launch on the companies own Antares 230 vehicle, which uses the Russia RD-181 engines. This was the seventh launch of Antares with six successfully completing their missions and one failure. That failure led to the redesign of the Antares rocket which caused a two-year delay in launches, during that time Orbital made use of United Launch Alliances Atlas V to launch Cygnus to the ISS.
In what looks to become another busy day for SpaceX the Dragon cargo vehicle that spent a month at the station following its successful launch last month was released by the station this morning and completed a successful splashdown in the Pacific Ocean at 8:12 EDT.
This was the second mission for this vehicle and clearly shows that SpaceX’s goals of creating reusable rockets and spacecraft have moved another important step forward.
The spacecraft returned 4,100+ lbs of research and other cargo from the station which will now be returned to port before being transported directly to NASA to be offloaded.
Good splashdown of Dragon confirmed—completing first re-flight of a commercial spacecraft to and from the @Space_Station.
At present SpaceX has not said when another flight-proven Dragon will be used however there have been indications that this is under consideration as well as the possibility of using flight-proven Falcon 9 to launch them.
Astronauts Peggy Whitson and Jack Fischer completed a 4 hours, 13 minute spacewalk successfully today, this was the 200th at the International Space Station.
The spacewalk which was shortened due to an issue with a Service and Cooling Umbilical hose used to provide power and consumables to the spacesuits while inside of the station, this resulted in both Astronauts having to share one reducing the overall battery time they had available.
However, despite this, they were able to complete the following tasks:-
At 3:13 AM EDT today the Soyuz MS-04 was launched from Baikonur to begin a four orbit, six hour journey to dock with the International Space Station (ISS).
For the first time since October 2005, the vehicle was only carrying two crew members instead of the typical three. This is due to a change made by Russian to switch to only having two crew members on board ISS.
This morning at 11:14 AM EDT United Launch Alliance (ULA) successfully launched another Orbital ATK Cygnus spacecraft towards the International Space Station (ISS). This was the third Cygnus that ULA has launched for Orbital and at the present time the last.
Named after the late John Glenn, former Astronaut and US Senator who passed away last December. The launch was delayed several times to allow ULA time to address some issues with the launch vehicle and pad, and then to accommodate the hectic ISS schedule. The vehicle is carrying 3,459 kg (7,626 lb) of cargo to the space station and will spend at least 80 days at the station before being released. After it is successfully completed its mission another of the Saffire experiments will be performed, where a controlled fire will lite. Once that is complete the vehicle will burn up in the atmosphere.
The countdown proceeded smoothly this morning with an on-time launch, which concluded when the Cygnus spacecraft was delivered to orbit.
This was ULA’s 71st Atlas V, 36th 401 config, 4th launch of 2017 and 119th consecutive successful launch keeping their perfect 100% record.
As a side note, this was the last launch for NASA PAO George Diller who has been the voice of NASA for many launches in the past. We hope that he has a great and long retirement and will miss hearing his commentary.
One of the experiments making its way to the International Space Station (ISS) today is the Advanced Plant Habitat (APH). As part of the journey to Mars and beyond being able to grow plants for eating will be very important. This experiment builds on the older Veggie experiment that has been active on the station for a while now.
APH will be an enclosed facility that will allow the team to control the environment including lighting levels, humidity, watering etc. Once installed on the station the first two plants to be grown are Wheat and Arabidopsis which will allow the scientists determine how the facility is operating and have well-known structures that have been studied on Earth.
As with the early Veggie experiments, the crew will not eat anything that has been grown initially, however, one of the scientists said during the NASA “What’s On Board” briefing mentioned.
The APH has the ability to grow four different plants even if they have different growth times, this could allow future crews to grow lettuce, tomato, onions and peppers and have a fresh salad.
NASA Astronaut Jeff Williams broke NASA Astronaut Scott Kelly’s record today for the longest cumulative time spent in space for a US astronaut. Jeff is on his fourth mission to space, which include one Space Shuttle mission and three long duration missions to the International Space Station.
For this current mission Jeff launched on March 18th, 2016 with Cosmonauts Aleksey Ovchinin and Oleg Skripochka aboard their Soyuz TMA-20M vehicle and docked at the station 6 hours later. Jeff later took command of the station just before the departure of previous commander NASA Astronaut Tim Kopra.
Jeff previous flew on STS-101, Soyuz TMA-8 (Expedition 13), Soyuz TMA-16 (Expedition 21/22).
Jeff will return to Earth in September having surpassed 533 cumulative days in space.
The Russian Progress MS-02 spacecraft launched successfully today beginning a two day journey to dock with the International Space Station.
Roscosmos elected to do the two day journey to allow time to fully test all the upgraded systems on the newer MS version of the vehicle. The first Soyuz MS crewed mission is due to launch in June and validation of the systems is required before that can occur.
This is the second of three cargo vehicles scheduled to travel to the station in less than a month.
European Space Agency Astronaut Tim Peake of the UK arrived at the International Space Station today following a smooth launch and four orbit accelerated rendezvous. Tim and fellow travelers NASA’s Tim Kopra and RSA’s Yuri Malenchenko lifted off from Baikonur Cosmodrome at 6:03 AM EST today and once in orbit begun there four orbit, six hour journey to the station.
The crew had to perform a manual docking after the KURS automated docking was aborted when the craft was just 20 metres away from the station.
Tim’s mission called Principia will see him stay at the station for six months during which time he will perform numerous experiments including interacting with two Raspberry PI’s that were recently launched to the station aboard the Cygnus spacecraft. The PI’s will be executing programs created by school children around the UK which were selected during a competition.
Tim is the second UK astronaut to travel into space and the first to the ISS, the previous traveler Helen Sharman visited the Mir station.
Current station commander Scott Kelly posted the following picture of the launch captured from the station today.
