China To Launch Space Station Module Prototype

During a 2010 presentation at the China Academy of Space Technology a full-scale model of Tiangong 1 was on display.

China’s space program is in the news again, this time with unconfirmed reports that the Tiangong 1 space lab may be launching into orbit sometime this year – possibly later this month.  Previous news reports cited potential launch dates in 2010 or 2011,  so this launch isn’t too far behind schedule.

What plans does China have for their first orbital space station prototype?

The space lab, named “Tiangong” translates from Mandarin Chinese into English as “Heavenly Palace”.  Weighing just under 9 tons, the prototype module will orbit for two years. China will use the module to practice docking maneuvers and test orbital technologies during the module’s lifetime.

China plans to follow the Tiangong 1 orbital lab with two more lab launches over the next few years to continue testing systems and technologies before starting construction on their own space station in the 2020’s.  Based on China’s current plans, the Tiangong orbital labs will not be used in the Chinese space station.

Many space analysts believe China’s lack of a perceived “space race” is a potential reason for the country’s slow, methodical space program build-up.  So far, China has only launched three manned space flights:  Shenzhou 5 and Shenzhou 6 ( 2003 and 2005, respectively). China’s first mission to include a spacewalk was Shenzhou 7 (2008).

While China is making great strides with their manned space program, there are no current plans to include China in the ongoing International Space Station project.  Despite several political and technological issues preventing China’s participation in the ISS, recent comments from officials at the China National Space Administration have indicated a willingness to allow other countries to visit the country’s space station once it is operational.

SpaceX: Dragon ISS Bound

Space Exploration Technologies (SpaceX) is preparing its next Dragon spacecraft for a trip to the International Space Station (ISS). SpaceX has worked over the last several months to make sure that the spacecraft is set for the Nov. 30 launch date that has been given to the commercial space company. If all goes according to plan, a little more than a week after launch – the Dragon will dock with the ISS.

NASA has technically agreed to allow SpaceX to combine all of the tests and demonstration activities that were originally slated to take place on two separate flights (COTS demo missions 2 and 3). SpaceX is working to further maximize the cost-effectiveness of this mission by including additional payloads in the Falcon 9’s second stage. These will be deployed after the Dragon separates from the rocket.

“SpaceX has been making steady progress towards our next launch,” said SpaceX’s Communications Director Kirstin Brost-Grantham. “There are a number of challenges associated with berthing with the International Space Station, but challenges are the norm here. With each mission we are making history.”

NASA is waiting to provide final approval of the mission’s combined objectives once any and all potential risks that are associated with the secondary payloads have been worked out.

The Dragon spacecraft needs extra electrical power to conduct station operations. That power is provided via two solar arrays, one of which is seen in this image. Photo Credit: SpaceX

There is a lot riding on the Commercial Orbital Transportation Services (COTS) contract. If crew members on the orbiting laboratory can access the Dragon’s contents and the spacecraft conducts all of its requirements properly – it will go a long way to proving the viability of NASA’s new path toward using commercial spacecraft and it could usher in a new era of how space flight is conducted.

It is hoped that private-public partnerships could lower the cost related to access-to-orbit and in so doing also help to increase the reliability, safety and frequency of space flight.

SpaceX has been working from milestone to milestone in getting the next mission ready to launch. Just this week the company conducted what is known as a wet dress rehearsal or WDR of the Falcon 9 rocket out at Cape Canaveral Air Force Station’s Space Launch Complex 40 (SLC 40). The Falcon 9 was loaded with propellant and went through all of the operations that lead up to launch – right down to T-1 second. At that point, the launch team stands down and the Falcon 9 is detanked.

SpaceX last launched from SLC 40 last December, during the intervening months the company has worked to upgrade the launch pad. New liquid oxygen or LOX tanks have been installed. These new tanks should streamline loading time from 90 minutes – to under 30 minutes. It is hoped that these efforts will allow the Falcon 9 to move from the hangar to liftoff – in under an hour.

SpaceX has launched the Falcon 9 twice and the Dragon spacecraft once – each completed the primary objectives successfully and helped to establish SpaceX as a leader in the NewSpace movement. SpaceX has inked many lucrative contracts, both domestic and foreign as a result. Besides the COTS contract, SpaceX is also one of the companies that has a contract under the Commercial Crew Development contract (phase-02) or CCDev-02.

This scene might play out for real in the coming months as SpaceX prepares to launch one of its Dragon spacecraft to the International Space Station. Image Credit: SpaceX

KENNEDY SPACE CENTER, Fla. – The Kennedy Space Center Visitor Complex in Florida is looking to take guests where no one has gone before. During the “Sci-Fi Summer” that is going on now through September at the Visitor Complex guests can see, sit and experience actual artifacts that appeared in the hit TV series and motion pictures.

Guests are greeted by two Starfleet officers; today they were Lieutenant Commander “Hawk” and T’Lanna. Both of whom were part of Starfleet’s temporal division. The fact that they were in the 21st Century and escorting guests around appeared to be a sore point with them – but more on that later.

Your other guide is T'lanna - knowledgeable - but has a bit of a temper. Photo Credit: Alan Walters/awaltersphoto.com

Throughout the Visitor Complex were items from the Star Trek Franchise. The original TV series was represented by the bridge of the Enterprise. Contained within the IMAX building, also has the portal from the original series episode “City on the Edge of Forever.” That is just a small part of the display that is spread throughout the Visitor Complex. One can even find the Scorpion Attack Fighter from Star Trek: Nemesis.

Subtly, here and there the operators of the complex show how science fiction and science fact are tied together. One in particular is a display showing size comparisons between Star Trek vessels and modern spacecraft including the International Space Station and the Saturn V rocket. This allows guests to see how fantasy relates to reality.

“There has always been a kind of synergy between science fiction and science fact, especially with the Star Trek franchise,” said Kennedy Space Center Visitor Complex Public Relations Manager Andrea Farmer. “We wanted to highlight and honor this – which is one reason we decided to extend the exhibit past summer.”

For both fans and non-fans alike, the exhibit is an addition that makes a trip to the Visitor Complex all the more entertaining. Just heed this advice – be nice to the Vulcan…

Shuttle Duo Nose-to-Nose Rendezvous highlights Retirement Duty

Space Shuttles Discovery and Endeavour meet for a nose-to nose encounter of gaping holes at the Kennedy Space Center on Aug. 11. The two NASA shuttles shorn of spaceflight maneuvering capability swapped locations to continue the transition to retirement and public display at museum in Virginia and California respectively.

To see one shorn shuttle is bad enough. Seeing two NASA space shuttles edged together and voluntarily gutted of their spaceflight capability for lack of Federal Government funding in the prime of their lives is beyond sad.

Two of NASA’s trio of space shuttle orbiters – Discovery & Endeavour – switched locations at the Kennedy Space Center (KSC) on August 11, moving them further down the path to eternal retirement and public exhibit at their future homes in museums. That’s far afield from their intended purpose to soar as spaceships of exploration to the High Frontier.

Discovery and Endeavour briefly met in a matchless nose-to-nose configuration for a roadside photo opportunity between the humongous Vehicle Assembly Building (VAB) and the processing hanger – dubbed the Orbiter Processing Facility – where the orbiters are prepared for flight.

Space Shuttle’s Discovery and Endeavour swapped places at KSC so that technicians could resume preparations towards the transition and retirement of shuttle Discovery – the first of NASA’s orbiters to be officially withdrawn from active duty spaceflight service.

First, Discovery was backed out of temporary storage from a high bay inside the VAB. Then Endeavour was towed out of Orbiter Processing Facility-1. Technicians then maneuvered the orbiters to a rendezvous point in between on the ground. Just imagine how grand this vista would have appeared in space.

At last Discovery and Endeavour met for the truly sad nosy encounter of gaping holes where the forward reaction control thrusters once fired to meticulously maneuver the shuttles in orbit. Protective plastic sheeting meant to shield the empty thruster bay from FOD – or Foreign Object Debris – was in tatters and whipping wildly in the wind almost from the moment Discovery emerged from the VAB.

The rear ends of both orbiters looked like the main engines had been sawed off. Both orbiters have been stripped of their trio of mighty space shuttle main engines (SSME’s) and duo of bulbous Orbital Maneuvering System (OMS’s) pods for months of decommissioning work.

Discovery was then pulled into the Orbiter Processing Facility-1 (OPF-1) where the next step is to extract even more of her guts, namely the Auxiliary Power Units (APU’s) and associated systems for “safing” over the coming months. In April 2012, Discovery is scheduled to depart KSC forever and be flown off for permanent public display at the Smithsonian’s National Air and Space Museum Steven F. Udvar-Hazy Center in Virginia.

Endeavour was towed into the VAB for storage until October, when she will be moved into OPF-2 for further work to ready her for public display at the California Science Center in Los Angles sometime next summer.

Atlantis is next on the chopping block. And America retains zero indigenous capability for human spaceflight.

The situation likely won’t change for at least several years until one of the commercial providers launches a human rated “space taxi” to low earth orbit.

JPL’s ‘Muscle Car’ – MSL – Takes Center Stage

JPL's 'Hot Wheels' - The Mars Science Laboratory or 'Curiosity' is being prepared to launch to mars this November. Photo Credit: Alan Walters/awaltersphoto.com

[/caption]
CAPE CANAVERAL, Fla. – NASA is experiencing what could be dubbed a “summer of planetary exploration.” With the Juno mission to Jupiter on its way as of Aug. 5, NASA is prepping not one but two more missions – this time to terrestrial bodies – specifically the Moon and Mars.

On Sept. 8 NASA is planning to launch GRAIL (Gravity Recovery And Interior Laboratory). This mirror image spacecraft consists of two elements that will fly in tandem with one another and scan the Moon from its core to its crust. This mission will serve to expand our understanding of the mechanics of how terrestrial bodies are formed. GRAIL will provide the most accurate gravitational map of the Moon to date.

When it comes to upcoming projects that have “celebrity” status – few can compete with the Mars Science Laboratory (MSL) or Curiosity. The six-wheeled rover was part of a media event Friday Aug. 12 that included the “Sky-Crane” jetpack that is hoped will safely deliver the car-sized rover the Martian surface. Also on display was the back half of the rover’s aeroshell which will keep the robot safe as in enters the red planet’s atmosphere.

Numerous engineers were available for interview, one expert on hand to explain the intricacies of how Curiosity works was the Rover Integration Lead on the project, Peter Illsley.

One fascinating aspect of MSL is how the rover will land. As it pops free of the aeroshell, a jet pack will conduct a powered descent to Mars’ surface. From there the rover will be lowered to the ground via wires, making Curiosity look like an alien spider descending from its web. Once the rover makes contact with the ground, the wires will be severed and the “Sky-Crane” will fly off to conduct a controlled crash. Ben Thoma, the mechanical lead on this aspect of the project, described how he felt about what it is like to work on MSL.

MSL is slated to launch this November atop a United Launch Alliance (ULA) Atlas V 541 rocket. If everything goes according to plan the rover will begin exploring Mars’ Gale Crater for a period of approximately two years. In every way Curiosity is an upgraded, super-charged version of the rovers that have preceded her. The Pathfinder rover tested out many of the concepts that led to the Mars Exploration Rovers Spirit and Opportunity and now MSL has incorporated lessons learned to take more robust scientific explorations of the Martian surface.

NASA’s GRAIL twins – dubbed GRAIL-A & GRAIL-B – are ready to embark on America’s next science expedition to the moon in less than 1 month’s time from Cape Canaveral Air Force Station, Fla.

The twin Gravity Recovery and Interior Laboratory (GRAIL) spacecraft have been exhaustively tested, fueled for flight and mounted side-by-side on a specially designed payload adapter inside the controlled environment of a clean room at the Astrotech Space Operations facility in nearby Titusville, Fla.

The next processing step is to encapsulate the lunar probes inside their protective payload fairing. The duo are set to be shipped from Astrotech to their Cape Canaveral launch pad next week on Aug. 16, where they will be mated to an already assembled Delta II booster.

Liftoff of the GRAIL twins is slated for Sept. 8 at 8:37 a.m. EDT by a Delta II Heavy rocket from Launch Complex 17 at Cape Canaveral for a nearly four month voyage to the moon.

After entering lunar orbit, the two GRAIL spacecraft will fly in a tandam formation just 50 kilometers above the lunar surface with an average separation of 200 km during the 90 day science phase.

GRAIL’s mission goal is to map the moon’s gravity field to high precision and thereby deduce the structure of the lunar interior from crust to core. This will also lead to a better understanding of the composition of the moon’s interior, according to Sami Asmar, GRAIL co-investigator from NASA’s Jet Propulsion Laboratory in Pasasdena, Calif., during an interview inside the Astrotech clean room at a photo opportunity for the media. A gravity experiment is also aboard the just launched Jupiter bound Juno spacecraft.

In Their Own Words: Experts Talk Juno

Several scientists and experts discussed the Juno mission to Jupiter with Universe Today. Photo Credit: Alan Walters/awaltersphoto.com

CAPE CANAVERAL Fla. – Many experts took time out of their hectic schedules to talk with Universe Today in the day leading up to the launch of the Juno spacecraft. Some even took the time to talk to us just minutes before the probe was scheduled to be launched on its mission. Check out what they had to say below:

Juno Project Scientist Steve Levin was at Kennedy Space Center to watch the Juno probe begin its five-year journey to Jupiter. He took a few minutes of his time to talk about what his expectations are for this mission.

Levin has been with JPL since 1990, one of the previous projects he worked on is the Planck mission which launched in 2009.

Levin believes that Juno could fundamentally change the way we view Jupiter. He was one of many VIPs that descended on Kennedy Space Center to watch as Juno thundered to orbit atop at Atlas V rocket.

Sami Asmar is part of the science team that is working on the Juno project. He was at the rollout of the Atlas rocket to the pad. Here is what he had to say about the mission (note the Atlas rocket moving out behind him).

Bill Nye the Science Guy was a very busy man while at Kennedy Space Center. He still took the time to chat with Universe Today about his views on this mission. Unfortunately, with little time to spare, we had to conduct the interview within minutes of the first launch attempt. A good chunk of Nye’s interview – was drowned out by the lead up to the countdown!

The usual launch of an Atlas consists of the launch team coming in, pushing a button and going home – the launch vehicle is that reliable. This day, things occurred quite differently. A technical issue coupled with a wayward boat that had drifted too close to the launch pad saw the launch time slip from 11:34 a.m. EDT to 12:25 p.m. When the rocket did take off however it was a spectacular sight to behold, faster than other iterations of the Atlas, it roared off the pad, sending Juno on its way to Jupiter.

SpaceX: Mars Is Our Future

Could an image similar to this be in our near future? If Elon Musk has his way - the answer is yes. Falcon 9 Image Courtesy of SpaceX - Mars Image Courtesy of NASA

[/caption]Elon Musk is not one to rest on prior accomplishments; he likes to continue to push forward – his plans for the future of commercial space flight reflect that philosophy. He has stated his plans to begin crewed flights to Mars. Musk thinks that humans can set foot on the red planet within the next 10 to 20 years. He stated that the rationale behind mankind becoming a multi-planet species should be obvious to all.

“Ultimately, it is vital that we are on a path to becoming a multi-planet species,” said Musk. “If we don’t then our future isn’t very bright, we’ll simply be hanging out on Earth until some calamity claims us.”

Musk made the announcement of his intent during this month’s meeting of the American Institute of Aeronautics and Astronautics (AIAA) that was held in San Diego, California.

SpaceX would presumably utilize the Falcon Heavy rocket, which is slated to conduct its first launch either at the end of 2012 or the beginning of 2013. Whereas the Falcon 9 features nine engines in its first stage, the Falcon Heavy, being a triple-body design similar of the Delta IV Heavy – would utilize 27 Merlin engines. It is estimated that the Falcon Heavy could send 12 to 15 metric tons to orbit.

The proposed Falcon Heavy is scheduled to launch either some time next year or in the early part of 2013. Image Credit: SpaceX

The spacecraft that would fly any mission to the red planet would theoretically be an offshoot of the vehicle that SpaceX sent to orbit last December, the Dragon. In fact the craft/project has already been dubbed the “Red Dragon.”

NASA currently plans to send astronauts to an asteroid by 2025 and to Mars sometime in the 2030s. If SpaceX is successful, this would be far faster than what the space agency has stated it is capable of accomplishing.

SpaceX has had a number of successes lately. It has successfully launched two of its heavy-lift Falcon 9 rockets, the second of which carried the first of the company’s Dragon spacecraft to orbit. Shortly thereafter the company recovered the vehicle as it bobbed safely in the Pacific Ocean after returning safely to Earth. The feat of sending spacecraft to and from orbit had only been accomplished by nations before this.

The NewSpace firm is working to speed up the timeline of the Commercial Orbital Transportation Services (COTS) contract, worth an estimated $1.6 billion, that the company has with NASA. SpaceX has requested and technically received permission to send the next Dragon spacecraft to the International Space Station (ISS) this December. Originally this flight would have been a flyby of the orbiting laboratory to test out several of the spacecraft’s key operating systems. However, one of the ISS partners, Russia, has yet to sign off on this plan however.

The California-based company was also tapped to participate in NASA’s Crew Commercial Development contract (phase 2) – more commonly known as CCDev-02. SpaceX was selected along with Boeing, Sierra Nevada Corporation and Blue Origin. Each firm was awarded a different cash sum to accomplish the proposals that they had set forth.

SpaceX is a company whose scope appears to be rapidly expanding. The announcement at the AIAA by Musk appears to highlight this fact. Mars has long been the destination of choice for many within the space community. Funding and logistics woes have delayed the first manned mission from ever taking place. It remains to be explained how the mission will be flown, will it be unilateral, multi-national or some other mixture? Will private industry take the lead? For his part Musk has thrown down the gauntlet – “Red Dragon” could fly as early as 2018.

Juno Spacecraft Honors Those Who Started It All

Juno begins its five-year journey to the planet Jupiter. On board are several artifacts meant to honor the history of the gas giant. Photo Credit: Alan Walters/awaltersphoto.com

[/caption]
The Juno spacecraft, now safely on its way to the planet Jupiter, is carrying along with it several artifacts in honor of its voyage. Onboard the probe are three, tiny figurines of key players in the mythological and historical background of the gas giant. LEGO figurines of the Roman god Jupiter, his wife Juno and Italian astronomer Galileo Galilei have had their 1.5-inch likenesses added to the voyage.

In Roman mythology Jupiter had cast a veil of clouds over himself to hide his activities. Undeterred, his wife, Juno, peered through the clouds to see Jupiter’s true nature. Hence, her representation onboard the Juno spacecraft – is holding a spyglass. The last member of this odd ‘crew’ is Galileo, the man who made a number of important discoveries regarding the Jovian system.

The inclusion of these three figures is part of a joint effort between NASA and the LEGO group to spark interest in Science, Technology, Engineering and Math or STEM in children. NASA went one step further in acknowledging the accomplishments of the man that made so many discoveries about this massive world. It has included a plaque in honor or Galileo.

During his life, Galileo contributed greatly to mankind’s understanding of the solar system. He discovered in 1610 what have since been dubbed the “Galilean moons” – Io, Europa, Ganymede and Callisto.

This plaque is affixed to the Juno probe bound for Jupiter. It shows an illustration of Galileo as well as an inscription he made regarding the gas giant. Photo Credit: NASA

The plaque was donated by the Italian Space Agency and it measures 2.8 by 2 inches (71 by 51 millimeters). The plaque is manufactured from flight grade aluminum and weighs six grams or about 0.2 ounces. The plaque includes an illustration of the famous astronomer along with an inscription – in his own hand – a passage he made in 1610 concerning his observations of Jupiter. The inscription reads:

“On the 11th it was in this formation — and the star closest to Jupiter was half the size than the other and very close to the other so that during the previous nights all of the three observed stars looked of the same dimension and among them equally afar; so that it is evident that around Jupiter there are three moving stars invisible till this time to everyone.”

Juno successfully lifted off from Cape Canaveral Air Force Station’s Space Launch Complex 41 at 12:25 p.m. EDT on Friday, August 5. It will take the probe about five years to reach Jupiter. Once there it will enter in a polar orbit around the world where it will use its suite of instruments to peer beneath the veil of Jupiter’s clouds to study the planet’s gravity, magnetosphere and whether-or-not the planet has a rocky core.

NASA’s Jet Propulsion Laboratory (JPL) manages the Juno mission for the principal investigator, Scott Bolton, from the Southwest Research Institute in San Antonio. The Juno mission is part of the New Frontiers Program managed at NASA’s Marshall Space Flight Center in Huntsville, Ala. Lockheed Martin Space Systems, Denver, built the Juno spacecraft.
