Those regular readers of my blog will notice, that things have been,how shall I say,somwhat ‘quiet’ on the article front of late. This is due to a personal matter, that for a while had a real effect on my life. I couldn’t do anything that involved any kind of effort, and while I LOVED creating articles, even that was just FAR too much effort.
Even this 1st post back is somewhat of a departure from my normal articles about space news and rocket launches? WHY?
Because I’d like to ask YOU a question
What are the sounds that relax you?
What are the sounds that, when you hear them, gives you a feeling of relaxtion and wellbeing?
After a hard day at work, what are the sounds, that when you hear them, make the tension simply ‘wash away’?
Over the last few months,sounds that helped me relax have included:
– Birds chirpping in a forest
– The sound of the sea lapping against the beach
– Wind in the trees
– Water in a stream
Relaxtion has had a very important part to play in the life recently, and I’m interested in what sounds make YOU relax; feel in control.
The United Launch Alliance Atlas 5 rocket (AV023) carrying the NROL-38 classified military satellite will launch tomorrow (20th June 2012) in the 401 configuration. Sounds impressively scientific, but what EXACTLY does that mean?
The First digit indicates the diameter (in metres) of the payload fairing, and always has a value of either 4 or 5. For the NROL-38 mission the payload fairing is 4 metres in diameter.
The second digit indicates the number of solid rocket boosters attached to the base of the rocket, and can range from 0 through 3 for the 4 metre fairing, and 0 through 5 with the larger 5-metre fairing. The Atlas V carrying NROL-38 mission has no additional solid rocket boosters.
The third digit represents the number of engines on the Centaur upper stage. This can be either 1 or 2. This particular Atlas 5 has 1 Centaur upper stage engine.
The Atlas 5 rocket is a very capable and reliable rocket, having had 29 successes of its 30 flights so far. Atlas first stage propulsion is provided by an RD-180 engine. This engine provides a single engine with 2 thrust chambers. It burns RP1 (Rocket Propellant 1 – highly purified kerosene) and liquid oxygen and provides 3,827 kN (Kilonewtons) of thrust at sea-level.
The Atlas 5 rocket is capable of carrying between 9 and almost 15 tonnes into low Earth orbit, and between 4 1/2 and 7 1/2 tonnes into a geosynchronous transfer orbit (dependent on exactly which configuration is used). It’s two designated launch facilities are at Launch Complex 41 (LC-41) at Cape Canaveral Air Force Station in Florida and Launch Complex 3 (SLC-3) at Vandenberg Air Force Base in California.
Recent missions that have used an Atlas 5 rocket include, Mars Reconnaissance Orbiter, Solar Dynamics Observatory, Boeing X-37B, Juno,
China yesterday launched its latest manned mission into space yesterday carrying 3 astronauts to their orbiting space laboratory, Tiangong-1.
The crew, two men and a woman, were lofted aboard a Long March 2F rocket today (Saturday 16th June) on schedule at 18:37 Beijing time (10:37 GMT, 11:37 BST).
The 3 crew members consist of:
Jing Haipeng, born in 1966 and Shenzhou-9´s commander.
Prior to becoming an astronaut, he was a fighter pilot in the People’s Liberation Army Air Force for 8 years.
Liu Wang, 42, served in the PLA for 6 years. With 1,000 hours of flying time.
Liu Yang, born in October 1978, China´s first female astronaut .
She has served in the PLA for 9 years, with 1,680 hours of flying time.
In 2010, she became a member of the second generation of Chinese astronauts.
The successful launch of Shenzhou-9 continues the incremental achievements China has made since the launch of the first Chinese astronaut into space in October 2003.
The Beijing command and control centre, over 1,600 km from the Jiuquan satellite launch centre, monitored the closing stages of the pre-flight and launch. The launch appeared to go flawlessly.
The Shenzhou-9 and its Long March 2F rocket were mated on the 7th June, and the final transfer to the launch pad occurred on 9th June.
Prior to launch, the Long March 2F is completely cocooned by its launch gantry. Around 45 minutes prior to launch the launch gantry was slowly removed from the lower section of the rocket, and then as the countdown nears completion, is retracted from the manned capsule segment.
The internal capsule view is very reminiscient of a Soyuz, with the 3 astronauts strapped into fairly cramped quarters. As the astronauts sit quite a way from the control panel, the Chinese have employed a similar mechanism to the Russians, with the introduction of a large metal pole that allows the pilot to press the appropriate button.
The Long March 2F rocket launched on time at 18:37 Beijing time and climbed effortlessly into a clear blue Chinese sky.
Apart from the initial launch fumes at the pad, which appeared a muddy brown, there was no characteristic launch plume showing its journey towards the heavens.
The Tiangong-1 laboratory is currently orbiting 343 km above the Earth in a circular orbit inclined at around 42 degrees.
Docking of the Shenzhou 9 capsule carrying the 3 Chinese astronauts, to the Tiangong-1 orbital laboratory is scheduled to occur at 15:00 Beijing time (07:00 GMT/UTC, 08:00 BST) on Monday 17th June.
The launch of an ILS Proton launch vehicle with the SES-5 satellite was postponed today (19th June 2012) due to technical reasons with the launch vehicle.
On June 18th, Khrunichev engineers at the launch site received an out of tolerance telemetry reading on a first stage subsystem during pre-flight testing. However, based on additional pre-flight testing performed on June 19, it was determined that further investigation is necessary, requiring the launch vehicle be returned to the processing hall for additional testing.
It has been emphasised that the vehicle and satellite remain in a safe configuration at the launch site.
The launch date will be determined at a later time.
Perhaps taking some of the shine off the Chinese launch today, the X37-B launch vehicle landed today (Saturday 16th June) at Vandenburg Air Force Base in California at 09:48 EDT after nearly 469 days (15 months) in orbit.
This was only the second flight of the military launch vehicle and smashes the previous test flight record (225 days) of the inaugural flight of the X37-B back in 2010. It was launched, in a mission designated USA-226, aboard an Atlas V rocket from the Cape Canaveral Air Force Station in Florida on 5th March 2011. The mission was classified and described by the U.S. military as an effort to test new space technologies. In late November 2011, the U S Air Force announced that it would extend the second mission of the X37-B beyond its 270-day duration.
Total mission elasped time at “wheel stop” was 468 days, 13 hours and 2 minutes. The craft orbited the Earth more than 7,000 times.
The X37-B craft is loosely based on the larger American Space Shuttle, carries no crew, and is a fully autonomous vehicle, capable of landing itself with no human intervention. Being almost 30 ft (9 metres) long, it is sent into orbit on top of an Atlas V rocket
The project was initially conceived by NASA,in conjunction with the US Air force, but due to budgetary contraints and other factors the project became the sole responsibility of the Department of Defence in September 2004. The nature of the mission was highly classified, with very few details being made available to the public.
In the almost endless cycle of new extra-solar planetary systems being discovered, this weeks discovery may lead scientists to re-appraise their theories of planetary formation.
The exoctically named GJ 1214b lies ‘just’ 40 light years from our solar system, orbiting a cool red dwarf star. The planet is said to be around 3 times the Earth’s diameter, but analysis by the Hubble space Telescope suggests a large percentage of its weight is water.
Added to the fact the planet orbits its parent star at a distance of only 2 million kilometeres, this makes GJ 1214b a VERY strange place indeed.
Questions scientists are asking include:
– How can water still be on the planet?
– Why was the planet not incinerated when the parent star turned into a red giant
– What form does water exist on a planet where temperatures reach in excess of 200 degrees centigrade?
I personally am looking forward to the answers.
On Friday 17th China launched another of its Beidou-2 navigation satellites. Launched from the Xichang space base in southwest China’s Sichuan province, the Long March 3C rocket lifted off at 16:12 GMT/UTC.
Beidou-2, which this satellite launch formed part, is the Chinese equivalent of the US global positioning system (GPS) system. It is hoped that by the time the system is fully operational, in around 2020, it will consist of around 35 satellites. Currently there are 11 satellites in the fleet.
Also on Friday, the MUOS satellite was lauched from launch complex 41 Cape Canaveral Air force Base. The Atlas V carrying the first MUOS (Mobile User Objective system) satellite for the American Navy lifted off at 22:15 GMT/UTC after a week of weather related delays.
MUOS is a narrowband satellite system that will provide the US military and its allies simultaneous voice, video and data capability by using advanced 3G mobile communications technology. Available 24/7,it greatly enhances the current capability by more than 10 times.
The complete MUOS system, once fully deployed, in around 2015, will be a four satellite system, with an in-orbit spare.
ESA contract signed
On Febraury 24th The European Space Agency (ESA), signed the biggest satellite construction contract in its history, a $1.8 billion, six-satellite deal with Thales Alenia Space to provide meteorological services from geostationary orbit for 20 years starting in 2017.
The first two satellites will be launched in 2017 and 2019, and will offer an all new infrared sounding capability and imaging of global lightning that will provide early warning of severe storms.
In a typically European decision, that was almost derailed by wranglings between Germany and France, many European Aerospace companies will see parts of the satellite contracts come to their countries.
This week marked as exciting week in space launches with 2 successful launches, a twice aborted launch, a 6 hour spacewalk and a postponed launch. Along with that was the initial submission by NASA of its suggested 2013 budget
The first launch of the week came from the European space Agency (ESA), and marked the inaugrial launch of the new small payload rocket VEGA. This took place on Monday 13th February. The launch took place from the ESA facility in Kourou and VEGA launched successfully at 10:00 GMT.
The rocket, mainly developed by the Italians has been in development since 1998. As this was the 1st qualification flight of the rocket, dubbed VV01, ESA offered the payloads, which included 7 pico (or cube) satellites from European universities, LARES (a Laser Relativity Satellite to test various aspects of general relativity) and ALMASat-1. a free ride. The mission performed flawlessly. The VEGA rocket is 30 metres tall, and weighs 137 tonnes at lift off, which is 1/6 the weight of a fully loaded Ariane 5 rocket.
ESA hope that VEGA will allow smaller payloads to be launched into orbit at a greatly reduced cost. Time alone will tell, if this turns out to be the case.
This week saw the launch, at the third attempt, of the SES-4 communications satellite. Originally delayed since late December 2011, this finally launched on 14th February at 19:36 GMT/UTC from the Baikonur Cosmodrome in Kazakhstan. The SES-4 satellite was carried on top of a Proton-M rocket standing 58 metres in height, weighing 705,000 Kg at lift off. The upper stage of the rocket was a Breeze-M upper stage.
Manufactured by Space Systems Loral, the SES-4 satellite is a hybrid satellite featuring both C and Ku-band payloads and provides enhanced coverage and capacity across Europe, the Middle East, Africa, Western Africa and Latin America. The satellites estimated lifespan is expected to be around 15 years.
First spacewalk of 2012
Cosmonauts aboard the International Space Station (ISS), Oleg Kononenko and Anton Shkaplerov spent 6 hours in the first spacewalk of 2012. They exited the PIRS module at 14:15 GMT/UTC on February. Wearing the Russian Orlan spacesuits, the cosmonauts had issues getting out of the hatch and were 20 minutes late starting their work. The main task was moving the Strela-1 crane from the PIRS module to the POISK module. The crane needs to be relocated so that the new Russian module, Nauka, can be installed by the Russians later in 2012.
They also installed a material experiment on the exterior of the station, and took samples from the station’s insulation to access its quality in protecting the station and also to assess the damage it has sustained so far. Due to the earlier tasks over-running the cosmonauts did not have the opportunity to install new debris shields on the Zvezda module.
The launch of a Proton-M rocket from Baikonur, carrying the Sirus FM-6 satellite that was supposed to launch in early March 2012, has been delayed for several months. It has been reported that technicians found problems with the solar panels attached to the satellite and that the satellite has now been returned to the manufacturer; Space Systems Loral.
The launch of the US Navy’s Atlas V rocket carrying the MUOS-1 (Mobile User Objective System) was twice postponed last week. On Thursday 16th February, the pre-planned 10 minute hold that occurs at T-minus 4 minuites was held at 5 minute intervals throughout the 45 minute launch window. This was to process high level wind data being sent by high altitude weather balloons that was preventing launch.
A final poll of the launch engineers gave a “GO” for launch, and the countdown proceeded at 23:25 GMT, until 1 minute and 14 seconds prior to launch an abort was signalled, again due to high level winds. As the abort came so close to the end of the launch window, the launch was immediately scrubbed for the day.
The following day the launch was also scrubbed; this time due to clouds and high level winds.
Launch engineers have now scheduled the launch of the MUOS-1 satellite to occur on the 24th February at 22:15 GMT/UTC. The launch window closes 44 minutes later at 22:59.
NASA Budget 2013
NASA announced on Monday 13th February a $17.7 billion budget request for fiscal year 2013. The budget includes $4 billion for space operations and $4 billion for exploration activities in the Human Exploration Operations mission directorate, including final close-out of the Space Shuttle Program, and funding for the International Space Station. $4.9 billion is allocated for science, $669 million for space technology and $552 million for aeronautics research.
What the figures don’t really show is that certain NASA budgets have been massively cut in order to continue funding the James Webb Space Telescope (JWST). Expenditure on the JWST, which has been plagued by cost overruns almost since the inception of the project, is set to increase to almost $700 million in 2014. To continue to fund the JWST, some projects, namely the 2016 and 2018 ExoMars missions, in collaboration with the European Space Agency will now not go ahead.
The budget will inevitably be trimmed by Congress, and in future years NASA sees its budget staying fairly flat in monetary terms.
The Progress craft that left Baikonur Cosmodrome on Wednesday has successfully docked with the International Space Station.
Docking occurred at 00:09 GMT/UTC on Saturday 28th January (19:06 EST Friday 27th January) approximately 250 statue miles above the Earth over the north east coast of Brazil.
The Progress craft conducted a fly-around of the ISS, before docking. After docking a period of “station keeping” was undertaken where all systems are checked to ensure correct operation. During this station keeping phase, the ISS and Progress craft maintain a safe distance between the 2 vehicles of around 200 metres.
Over the next few hours, various leak tests will be conducted to ensure a successful docking, before any personnel are allowed onto the Progress vehicle.
For more information about this resupply mission, about the launch and what the cargo manifest is, see following stories:
The latest unmanned Progress cargo ship (M-14M or 46 depending on your chosen designation), has successfully launched from the Baikonur Cosmodrome in Kazakhstan on its 2 day journey to the International Space Station (ISS).
The launch, atop a Soyuz-U rocket, was from Site 1/5 at Baikonur, and took place from the same launch pad that launched Yuri Gagarin into space back in 1961.
Final launch preparations started on Tuesday morning, after sunrise, when the Progress craft was taken, as is customary, by rail, lying horizontally on the rail car,from the processing hanger at the Baikonur cosmodrome.
It was then hydraulically lift into a vertical position, and the launch platform was inclined to the proper angle for launch.
It was very cold at the launch site with temperatures of around 5 degrees farenheit being recorded.
The launch of the latest Progress vehicle is the culmination of a series of carefully choreographed steps. These started on Tuesday with the undocking, from the PIRS docking module, on the Russian segment of the space station, of the previous Progress resupply ship.
After undocking from the ISS, the Progress craft was positioned in a higher orbit to deply the CHIBIS-M micro satellite. (For more details of the CHIBIS-M mission, click HERE. After successfully deploying the micro satellite, Russian controllers fired the engines for the Progress vehicle to burn up in the upper atmosphere over the Pacific Ocean.
The Progress M-14M craft contains almost 2.5 tonnes of supplies for the personnel aboard the ISS. The craft contains:
Main flight components (total weight – 1,259 kg) consisting of:
Fuel in the tanks refueling system
Gas in cylinders of oxygen
Fuel in the tanks of the DCD for use on the ISS
Cargo delivered in a sealed compartment (total mass – 1,410 kg) consisting of:
Equipment for life support (GM)
Equipment for water supply (WAS)
Equipment to ensure the thermal regime (Comp)
Command and control equipment “Regulus-OS”
Traffic control and navigation (ship), telephone and telegraph communications (STTS), control onboard equipment (Suba)
Means maintenance and repair (STORA)
Funds sanitary services (SSGO)
fire protection (DPSS)
Funds intermodule ventilation (SMV)
containers with food rations, fresh food
Medical equipment, clothes, personal hygiene, clean air controls and cleaning station
Equipment FGB “Zarya”
Equipment SB-1 “Pirs”
Equipment for MIM-1 “Dawn”
Equipment for MIM-2 “Search”
Equipment for scientific experiments, “Typology”, “Immune,” “Biodegradation”, “Matryoshka-R”, “Endurance”, “Test”

Set items for the Russian crew members
Equipment for the U.S. segment, including food, sanitation and hygiene facilities to ensure
The Progress craft, lifted off, flawlessly at 23:06:40 GMT/UTC on Wednesday.
Maximum dynamic pressure (or MAX-Q) occurred around 65 seconds into the flight. This is the point at where the pressures on the space ship, from the speed traveled and the density of the atmosphere is at its greatest.
The 4 strap on boosters and first stage were separated as the craft attained 3,500 miles an hour, 2 minutes and 6 seconds after lift off. The first stage is 68 feet in length and 24 feet in diameter and burns liquid fuel.
Most of the recent issues with the Soyuz launchers have revolved around problems with the third stage of the rocket. I imagine therefore, that during this phase, Russian flight engineers were holding their breath. They needn’t have worried, as the stage burned perfectly and confirmation that a successful preliminary orbit had been reached was relayed just over 10 minutes after launch.
Once Progress attained its preliminary orbit, the solar arrays and navigational attenna were successfully deployed. At this point, flight control was passed to the Russian mission control headquaters in Korolov near Moscow.
The Progress now begins a 2 day catch-up to the ISS. 2 rendezvous burns are planned for Tuesday, 1 for Thursday before the final automated rendezvous process starts on Friday.
The Progress vehicle is due to dock at the PIRS module of the ISS at 00:08 GMT/UTC on Saturday morning (04:08 Moscow Time. 19:08 EST on Friday)
At the time of launch, the ISS was orbiting 240 statue miles above the central African country of Chad, moving in a South West to North Easterly direction. The 6 astronauts (a full complement) were asleep during the launch.
After the Progress M-14M craft docks to the ISS, it will remain their until April 24th, when it will make way for the next Progress vehicle.
There are 3 unmanned resupply ships that ferry supplies the ISS. Progress, the Russian craft makes 4 visits a year. ESA provide the Automated Transfer Vehicle, the 3rd of which is due to launch from Kourou on March 9th.
The third resupply vehicle is provided by the Japanese space Agency. It is called the H-II Transfer Vehicle (HTV) and the third one is due to dock with the ISS later in 2012.
