The STS-135 crew of space shuttle Atlantis and the Expedition 28 crew of the International Space Station were treated with great views of the Aurora Australis. Here’s one shot the crews photographed, showing a panoramic view of the station/shuttle complex along with several different astronomical beauties! The aurora shows up brightly, but what else is in the image? Looking closely –and southern hemisphere observers might recognize some objects better — but do you see the globular cluster Omega Centauri, the Coalsack Nebula and the Southern Cross? Anyone see anything else?
See below for another great aurora shot from the ISS, where the green glow shows up even better:
These images were taken on Thursday during one of the “night” passes for the station/shuttle. The astronauts mentioned the aurora during media interviews on Friday. “We saw an incredible Southern Lights aurora,” said STS-135 pilot Doug Hurley. “It was the best one I’ve seen in my two spaceflights. It was just unbelievable, the view out the cupola.”
CAPE CANAVERAL, Fla. – The U.S. Air Force launched the GPS IIF-2 satellite into orbit Saturday (July 16) on a mission to enhance the country’s constellation of Global Positioning System satellites. The satellite was launched atop a Delta IV Medium 4, 2 rocket from Cape Canaveral Air Force Station’s Launch Complex 37B at 2:41 a.m. EDT. The Delta IV had been scheduled to launch two days prior but slipped one day due to a technical issue with the satellite and a second day when technicians were prevented from rolling the Mobile Service Tower or MST back because of weather.
This morning’s launch
The rocket was provided by United Launch Alliance (ULA) and the company oversaw the liftoff. This configuration of the Delta IV Medium has two solid rocket boosters which are provided by Utah’s Alliant Techsystems (ATK). The boosters are required to provide the extra boost required to send the spacecraft into the correct orbit.
Weather was the biggest concern for the launch, but when the clock reached zero the launch vehicle thundered off of the pad in a spectacle of sound and light. The weather turned out to be a non-issue with mostly clear moonlit skies and almost no breeze. Lightning could still be seen lighting up the Florida sky off in the distance – but the summer light show only served as a backdrop for the launch.
“This is an exciting time for ULA, we are happy to have launched our 52nd mission,” said United Launch Alliance Spokesman Chris Chavez. “We’re happy to support the U.S. Air Force along with our customer and partner Boeing – it was a great launch and a great morning.”
The satellite
Boeing is the prime contractor that provided the U.S. Air Force with the GPS satellite. The GPS IIF system is expected to provide next-generation performance to the GPS constellation of satellites. These abilities are considered to be vital to U.S. national security as well as maintaining the GPS constellation’s availability for civil, commercial and military requirements. The IIF is expected to provide enhanced capability and better performance.
The first GPS IIF satellite was launched in 2010. It is hoped that the pulse-line production method that is employed by Boeing will ensure that the IIF fleet is placed on orbit on schedule. This production method is very similar to how airplanes are developed. The process is named because satellites are moved from one work station to the next in a steady rhythm – similar to a pulse.
The GPS IIF-2 satellite will be utilized for both for civilian and military purposes. A new civilian L5 signal will assist with search and rescue missions, while the military will benefit from the satellite’s resistance to jamming. The satellite also has a reprogrammable processor that can receive uploads on-orbit. GPS IIF-2 has a design life of 12 years and it is hoped that it will provide long-term service will keeping operating costs low.
“The enhancements that the GPS IIF-2 satellite has should strengthen the constellation for many years to come,” said Boeing Spokesperson Angie Yoshimura.
President Barack Obama called out for pizza today and ending up talking with the crews of STS-135 and Expedition 28 on the International Space Station. Well, that was his story anyway, but he did talk with the crews, offering a challenge for commercial space companies, as well as remembering the first flight of cooperation between the US and the Soviet Union – the Apollo-Soyuz test project which launched 36 years ago today — and reiterating the challenge of sending humans to Mars.
The STS-135 crew brought a flag that was flown on STS-1, the first shuttle mission, up to the ISS. “We’ll present the flag to the space station crew and it will hopefully maintain a position of honor until the next vehicle launched from US soil brings US astronauts up to dock with the space station,” STS-135 commander Chris Ferguson told the president.
Space Shuttle Discovery was briefly on public display on Wednesday July 13 as she emerged from the hanger at the Kennedy Space Center where she has been undergoing processing for retirement since her final landing on the STS-133 mission.
It was a rather stark and sad moment because Discovery looked almost naked and downtrodden – and there was no doubt that she would never again fly majestically to space because huge parts of the orbiter were totally absent.
Discovery was stripped bare of her three main engines and orbital maneuvering pods at the rear and she had a giant hole in the front, just behind the nose, that was covered in see through plastic sheeting that formerly housed her now missing forward thrusters. Without these essential components, Discovery cannot move 1 nanometer.
When the Space Shuttle is forcibly retired in about a week, America will have no capability to launch astronauts into space and to the International Space Station for many many years to come.
Discovery was pulled a quarter mile from the Orbiter Processing Facility (OPF) to the Vehicle Assembly Building (VAB) to make room for Space Shuttle Atlantis when she returns next week from the STS-135 mission, according to Stephanie Stilson, the flow manager for Discovery, in an interview with Universe Today.
STS-135 is the 135th and final mission of NASA’s 30 year long Space Shuttle Program.
NASA now only has control of two of the three shuttle OPF’s since one OPF has been handed over to an unnamed client, Stilson said.
Stilson is leading the NASA team responsible for safing all three Space Shuttle Orbiters. “We are removing the hypergolic fuel and other toxic residues to prepare the orbiters for display in the museums where they will be permanently housed.”
“The safing work on Discovery should be complete by February 2012,” Stilson told me. “NASA plans to transport Discovery to her permanent home at the Smithsonian Air and Space Museum on April 12, 2012, which coincides with the anniversary of the first shuttle launch on April 12, 1981.”
Always a good show and a unique, fun view, NASA released today the videos taken from the cameras mounted on the solid rocket boosters for Atlantis’ launch for the STS-135 mission.
CAPE CANAVERAL Fla. – As Florida’s Space Coast braces for the end of the shuttle program this month, signs of life after shuttle are starting to emerge. Space Exploration Technologies (SpaceX) returned the Dragon Spacecraft that launched this past December to Cape Canaveral Air Force Station. The Dragon however, was not alone. Two more capsules, one a test article, the other a mock-up were on display at Kennedy Space Center’s press site, signaling the coming way of the future for human spaceflight.
The Dragon Spacecraft was on display outside of Cape Canaveral Air Force Station. Placed between SpaceX’s Launch Control Center (LCC) and the U.S. Air Force Space and Missile History Center, the Dragon’s scorched hull was displayed to remind Space Coast residents that the space program was not retiring along with the shuttles.
“A lot of people are sad that the shuttle program is ending, it has been such an integral part of the area for three decades that they have a right to feel this way,” said SpaceX’s Vice President of Communications, Bobby Block. “Just because the shuttles are retiring however, does not mean that the entire space program is ending – it’s not over – it is the ending of one program, but it also is the start of another.”
That sentiment was shared by Lockheed Martin who brought their Orion Multi-Purpose Crew Vehicle to sit near the iconic Countdown Clock, a mere 3.5 miles away from shuttle Atlantis out at Launch Complex 39A. At first glance the fact that the capsule was still chained to the back of a trailer appeared to suggest that its appearance was rushed but in fact it highlighted a campaign by Lockheed Martin to let the public view Orion.
“We were taking the Orion to Kennedy Space Center so we took the opportunity to stop along the way,” said Lockheed Martin’s Communications Manager for the Orion Project Linda Singleton. “This way we could tell the public about the Orion Program, let them see the spacecraft first hand. We stopped at Tucson, Austin and Tallahassee and met with 20,000 people in person across the country and talked to them about Orion.”
Not to be outdone, the Boeing Company had a replica of its CST-100 Space Taxi – split down the middle allowing guests to get an up close and in-depth look at the capsule-concept that it is submitting, in collaboration with Bigelow Aerospace, as their entry for NASA’s Commercial Crew Development (CCDev) program. If chosen, it would be used to ferry astronauts to the International Space Station. Boeing also had a structural article on display nearby.
“The reason we selected a capsule is that it is a simple system, we’ve been flown since John Glenn did his first flight on Mercury,” said Boeing’s Vice-President and Program Manager of Commercial Crew Programs John Elbon. “The purpose of this transportation system is just to take passengers to the space station, so our design is focused on that mission.”
The numerous capsules on display as well as other “Space-Taxi” systems such as the one proposed by Sierra Nevada highlight efforts to shrink the human space flight gap that will start on July 21, when Atlantis conducts its final wheel stop. With the number of spacecraft that have flown, are being tested or just now emerging off the drawing boards it is possible that the U.S. might have a variety of craft for a wide range of missions. For now however, NASA will have to rely on Russia’s Soyuz Spacecraft.
Videographers David Gonzales, Kurt Johnson and Mike Deep filmed the final launch of the Space Shuttle from the Kennedy Space Center Press Site. The team used multiple cameras along with a high definition stereo audio recording device to capture the sights and sounds as Atlantis thundered into orbit. The goal was to provide the closest launch experience for the viewer without actually being there.
A Space Shuttle launch is a spectacle that will never again be seen. The sequence begins with a tight shot of the pad in the final seconds of the count. As the 3 Space Shuttle Main Engines ignite they flash water from the sound suppression water system into steam, sending a plume billowing away. The entire stack rocks a couple of feet before settling back vertical. The Solid Rocket boosters ignite, launching out a second plume and lifting the 4.5 million pound stack off the ground. Spectators erupt into cheers and the shutters of thousands of press cameras click away.
I’m just making out my shopping list for going to the grocery store tomorrow, and it includes everything I need to share a virtual dinner with the astronauts in space on Thursday, July 14. And no, unfortunately, I’m not launching to the ISS to join them. Food scientists at NASA’s Johnson Space Center in Houston thought it would be fun to give the crew an “All American Meal” — a typical American meal for the final mission of the shuttle and invite the public to join in by preparing the same food. Whatever you prepare it will be more aesthetically pleasing than the rehydrated food in plastic bags the shuttle and ISS crews will eat. Here’s the menu:
An appetizer of brie cheese, crackers and sausage; your choice of grilled chicken (which the shuttle crew will eat) or beef brisket (which will be enjoyed by the ISS crew), Southwestern corn and baked beans. The ISS crew will have beef brisket instead of chicken, but will enjoy the same side dishes as the shuttle crew. Desert for both crews consists of apple pie. The meal concludes with the quintessential American dessert, apple pie.
“Since the mission is in July, we thought it would be fun to have a typical summer meal often enjoyed in our backyards with friends and family,” said Michele Perchonok, NASA food scientist and manager of the shuttle food system.
For the special space recipes or “formulations” as they are called by NASA food scientists, plus more information, video and imagery, visit this NASA webpage.
The crackers, brie, sausage and apple pie are commercial off-the-shelf products repackaged for spaceflight. NASA food scientists prepared the chicken, brisket, corn and beans in a laboratory at Johnson before the mission.
NASA didn’t specify what time the astronauts will be eating their All American Meal, so you can eat at any time during the day and know you’re eating the same thing as the astronauts in space did. Well, pretty close to the same thing anyway. Hopefully those of us sitting on Earth don’t have to rehydrate our food and eat out of plastic bags.
It’s the end of an era: the final spacewalk during the space shuttle era was conducted by astronauts on July 12, 2011 during the final shuttle mission, STS-135. This is the 160th spacewalk supporting assembly and maintenance of the space station and the 249th EVA conducted by U.S. astronauts. The two spacwalkers were actually from the International Space Station crew, Expedition 28’s Mike Fossum and Ron Garan, but were assisted by the shuttle crew. Shuttle Pilot Doug Hurley and Mission Specialist Sandy Magnus operated operate the station’s 58-foot-long Canadarm 2 to maneuver the spacewalkers around during the spacewalk.
A next-generation plasma rocket being developed by former NASA astronaut Franklin Chang Diaz called the Variable Specific Impulse Magnetoplasma Rocket (VASIMR) has been touted as a way to get astronauts to Mars in weeks rather than months, as well as an innovative, cheap way to re-boost the International Space Station. But in a biting commentary posted on Space News and the Mars Society website, “Mars Direct” advocate Robert Zubrin calls VASIMR a “hoax” saying the engine “is neither revolutionary nor particularly promising. Rather, it is just another addition to the family of electric thrusters, which convert electric power to jet thrust, but are markedly inferior to the ones we already have,” adding, “There is thus no basis whatsoever for believing in the feasibility of Chang Diaz’s fantasy power system.”
The VASIMR uses plasma as a propellant. A gas is ionized using radio waves entering into a plasma state. As ions the plasma can be directed and accelerated by a magnetic field to create specific thrust. The purported advantage of the VASIMR lies in its ability to change from high impulse to low impulse thrust as needed, making it an ideal candidate for a mission beyond low Earth orbit.
Chang Diaz’ company, the Ad Astra Rocket Company successfully tested the VASIMR VX-200 plasma engine in 2009. It ran at 201 kilowatts in a vacuum chamber, passing the 200-kilowatt mark for the first time. “It’s the most powerful plasma rocket in the world right now,” said Chang-Diaz at the time. Ad Astra has signed a Space Act agreement with NASA to test a 200-kilowatt VASIMR engine on the International Space Station, reportedly in 2013.
The tests would provide periodic boosts to the space station, which gradually drops in altitude due to atmospheric drag. ISS boosts are currently provided by spacecraft with conventional thrusters, which consume about 7.5 tons of propellant per year. By cutting this amount down to 0.3 tons, Chang-Diaz estimates that VASIMR could save NASA millions of dollars per year.
For the engine to enable trips to Mars in a reported 39 days, a 10- to 20-megawatt VASIMR engine ion engine would need to be coupled with nuclear power to dramatically shorten human transit times between planets.
Zubrin is the president of the Mars Society and author of the book “The Case for Mars: The Plan to Settle the Red Planet and Why We Must.” He has long touted the “Mars Direct” approach of getting humans to Mars to create a sustainable human settlement. The plan includes a series of unmanned and human flights to Mars using existing technology, as well as “living off the land” on Mars by creating rocket fuel to return to Earth, and using underground reservoirs of water on Mars.
In his commentary on VASIMR, Zubrin says, “existing ion thrusters routinely achieve 70 percent efficiency and have operated successfully both on the test stand and in space for thousands of hours. In contrast, after 30 years of research, the VASIMR has only obtained about 50 percent efficiency in test stand burns of a few seconds’ duration.”
On the ‘39 days to Mars’ claim, Zubrin says VASIMR would need to couple with a nuclear reactor system with a power of 200,000 kilowatts and a power-to-mass ratio of 1,000 watts per kilogram, while the largest space nuclear reactor ever built, the Soviet Topaz, had a power of 10 kilowatts and a power-to-mass ratio of 10 watts per kilogram.
Zubrin has invited Chang Diaz to a formal public debate the VASIMR at a Mars Society convention in Dallas next month.
