ISS: Progress Spacecraft Docking Test Completed

Progress M-21M  during docking test.

I have to admit, the look of a Russian spacecraft is growing on me. Although very cramped for space travelers, and certainly with this design "form meets function," the graceful maneuvering  of a spacecraft with its parallel solar panels looking like a pair of wings is pretty cool. On Friday cosmonauts onboard the International Space Station redocked the robotic-controlled Progress M-12M spacecraft to the Russian module. Also designated Progress 53, the Russian craft had docked with the ISS back in November, bringing up needed supplies and equipment. The spacecraft sported the new KURS-NA automated docking systems, which allows for an easier r robotically controlled approach and docking. About 60 feet away from the station, the system suddenly suffered a glitch and required Oleg Kotov to use the station arm to grapple the craft and dock it manually. DUring this test, the craft undocked on April 23 just ahead of a planned EVA by American astronauts. The cosmonauts carefully ran the craft with help from ground engineers, testing maneuverability and robotic procedures. On April 25th, the tests were declared complete and the Progress redocked to the ISS. Ground engineers will spend the next couple of days studying the flight data.

Basically the Dragon resupply craft has a similar configuration to the Russian one, that is, with extended "wing" solar panels, a service module, and a cargo capsule. It does not have a disposable science module. The front science module on the Russian spacecraft is left over from the manned Soyuz capsule design, and in the case of a Progress mission, used for carrying more cargo. The true difference between the two designs, is that the Russian craft gets filled with waste and is then is "disposed of" by undocking it and letting it burn up during re-entry over the ocean. The Dragon capsule gets filled with items needed back on Earth, separates from the service module and is returned safely by parachute after de-orbiting.

During the EVA last week, astronauts successfully replaced a backup computer system that would control the orientation of the solar panels of the ISS. In a short couple of hours, the astronauts again made the spacewalk look easy, despite the always-dangerous environment of outer space. 

Update: From the April 20th docking of the SpaceX Dragon. Japanese astronaut and Expedition 39 commander Koichi Wakata (in blue) and NASA Flight Engineer Rick Mastracchio use the controls of the ISS robotic arm to grapple the Dragon once it moved into position near the station. NASA publishes the best of their activity photos within a few days after the event, so I get to "revisit" the event if I want to link to the improved images. As usual, uncredited photos on this blog are usually from NASA itself.

What's next for ISS? Of course every day brings astronaut activity inside the station, maintaining equipment, exercising to fight the effects of weightlessness, performing experiments and preparing for special events. The Progress 53 spacecraft will stay at the station until June 9. On May 29 Tuesday, it's thrusters will be used to orient the station for an upcoming May 13 undocking of the Soyuz TMA-11M which will carry Mikhail Tyurin, Koichi Wakata, and Rick Mastracchio back to Earth, edning Expedition 39. COming to replace them will be Expedition 40/41 crewmembers Max Suraev, Reid Wiseman, and Alexander Gerst, who will blast off from Kazakhstan on May 28.

50 Years Ago: 1964 New York World's Fair

U.S. Space Park at the World's Fair in 1964: Showing off American space efforts to the world.

Fifty years ago an excited world gathered in New York to see exhibits from all over the globe displayed for visitors to see, to touch, and take pictures to share with folks back home. Each participating country wanted to show off their best and brightest developments, and so it comes as no shock that the Americans wanted to show off their advancing space programs.

Centerpiece of the World's Fair: the Unisphere, which is still in that same position in New York today.

With the Mercury manned space program completed, NASA was starting Project Gemini and developing the Apollo program to land on the Moon. While the Soviets still seemed to be ahead in their space program, America was catching up and the people wanted to see more of it. The US Space Park included a full-scale mockup of the bottom section of the Saturn first stage and its five giant motors; a Titan rocket with a Gemini Capsule; an Atlas rocket with Mercury capsule; a Thor-Delta rocket; The Mercury capsule Aurora 7 flown by Scott Carpenter; a full-scale model of an X-15 research rocket plane; an Agena upper stage; a mockup of the Gemini capsule,; mockups of the Apollo COmmand and service modules and LEM lander; and more than a half dozen mockups of important space probes and satellites.

Model of the Fair.

Now I move off on a slightly different tangent. The 1964 World's Fair was not only noticeable for its US Space Park. Many other American manufacturers we present, showing off the latest technology and how it would impact American society. IBM, Coca-Cola, Bell Telephone, and dozens more set up exhibits, pavillions, and built buildings and entertainment rides to display their leadership in American technology. ANd some of them asked for help to make their displays more memorable. For some, they turned to the master of showmanship, Walt Disney. And Walt used the opportunity and the funding to create some truly innovative rides and exhibits. This new entertainment technology would be used later as he rebuilt them in Disneyland after the Fair closed at the end of 1965. See how many you've interacted or seen yourself, years later!

Yes, that's right - "It's A Small World" is now 50 years old this month. Sponsored by the Pepsi-COla company. If you're a fan of IASW, go have a Pepsi today.

From GE's Progressland guidebook. GE sponsored and funded the "Carousel of Progress" which featured the use of Disney's new "Animatronic" robots used in place of actors. The Carousel of Progress can be found today only in Magic Kingdom in Florida. I made SURE to ride the moving stage when I last visited there in March. 50 Years old and still awesome!

The pinnacle of animatronics. Sponsored by the state of Illinois, "Great Moments with Mr. Lincoln" was a stage show which featured parts of Lincoln's speeches. The robot stood up, moved, talked, and seemed life-like. The exhibit was quickly duplicated at Disneyland before the World's Fair ended, and lasted many years. When the Disney company closed the event, public outcry was so much that it was soon reopened with improvements. Today you can see a newer, first ever, electric Autonomotronic figure in "The Disneyland Story Featuring Great Moments with Mr. Lincoln" in the Disneyland Main Street. Lincoln can also be seen in the "Hall of Presidents" in Liberty Square at Magic Kingdom in Florida.

Excited fair-goers ride the "Ford's Magic Skyway" in an actual Ford convertible (without actual motor). The car is controlled underneath the "skyway" by a prototype of what would later become the PeopleMover ride system (which is still today in the Magic Kingdom in Florida, one of my favorite rides). 50 FOrd automobiles including Ford Mustangs moved along a track featuring scenes exhibiting full-size animatronic dinosaurs and cavemen. Those robots would be later moved to Disneyland, where they feature in a musical diorama  joining the original Grand Canyon as Primeval WOrld. The Disneyland Railroad brings passengers slowly through the exhibit while the "Grand Canyon Suite" plays in its respective scene, and the Rite of Spring music from the movie Fantasia played in Primeval World. Though the dinosaurs look dated, at the time they were as correct as they could be for 1964.

The automated car ride moves passengers into the Skyway tunnel. I haven't figured out yet why it was called a skyway.

Passengers are greeted by scenes from the world of Dinoasurs. There were several exhibits at the Fair featuring dinosaurs including life-size dinos exhibited by the oil company Sinclair, which uses a dinosaur as it's logo.

Short EVA to Repair ISS Computer

Astronaut Rick Mastracchio working on the S0 Truss segment computer.

NASA includes redundancy on many items because when something breaks in space, you can't just run down to the local Apple Store for a fix. Last April 11, during a routine check, the backup computer MDM  for the test failed. The main computer still functioned, so the crew was in no risk of losing capabilities, but the backup needed to be replaced. There are 45 MDM computers on the station and this set controlled the Truss systems as well as the mobility of the adjustable solar panels. The Truss is the framework backbone of the ISS, on which hang all the solar panels and modules. This backup computer has been working ever since this S0 section had been delivered to the station by shuttle.

As the station flew into the Earth's shadow, the astronauts had to rely on their suit lights.

No Problem. Back in 2001 the space shuttle Endeavor had brought up a spare MDM which was then stored in the US-built Destiny module. During a short spacewalk yesterday morning astronauts Rick Mastracchio and Steve Swanson floated over to the Truss segment housing the failed computer and replaced it with the spare. All systems are working fine now, and the astronauts returned in what seemed to be a very short time.

Dragon Capsule Docks at ISS

Did the Easter Bunny arrive at the ISS on Easter morning? Well, there might be a little stuffed bunny inside, but actually it's SpaceX's Dragon unmanned cargo spacecraft that was grappled by the Station's robotic arm this morning and docked to an open port. The docking was secured at 8:06 AM MDT.

On the other side of the dock. Astronauts prepare to match atmospheres and make sure all the berthing steps have been completed, then need to equalize the pressures. Opening will occur tomorrow morning.

The third successful mission of a dragon resupply spacecraft brings about 2.5 tons of supplies to the ISS, including some new science experiments, and a set of robotic legs for the robot R2, which currently has only a torso, arms, and head.

View from the other side of the pad. Blastoff went very well!

After MECO (Main Engine CutOff) the first stage fell away and the second stage boosted the payloads into orbit.

Coming up on the ISS: Members of the Expedition 39 crew are preparing the Russian Progress 43 spacecraft for undocking on April 23, to test out the Kurs radio navigation system, and then redock it on April 25th.  Also on the 23, astronauts will perform a 2-3 hour EVA to replace a malfunctioning computer part on the Truss.

SpaceX Gets the Big Pad

NASA and SpaceX officials announce historic deal next to Pad LC39A.

While I was busy posting about important events from 50 years ago, some new historic events were taking place at the Kennedy Space Center. Just before SpaceX was scheduled to launch another Dragon cargo spacecraft to the International SPace Station, NASA and SpaceX officials held a press conference to announce that the Famous LC39A launch pad would be turned over under a lease to SpaceX.  Although the launch was scrubbed due to a helium leak (rescheduled now for Friday afternoon), the historic deal means that SpaceX will now control and modify the launch pad and tower where Apollo rockets sent men to the Moon and Space Shuttles into orbit.

From Mission STS134: Shuttle Endeavor sit s on pad 39A for its last mission to the ISS.

Until now, SpaceX had been in the running against space competitor Blue Origin (which is designing a crew orbital vehicle of their own) who had teamed with ULA (United Launch Alliance, which manages rocket launches for NASA). Recently, fearing that NASA was leaning towards deciding in favor of SpaceX, Blue Origin filed a complaint with the government that their own program better matched NASA's requirements for management of the site. The government office turned down the protest, stating that NASA had not claimed a preference of approach. SpaceX won the contract.

Pad 39A was originally host to the Saturn V launches of the Apollo era. The Saturn V was the heavy lift vehicle that took men and equipment to the Moon, and later placed the Skylab space station in orbit. SpaceX intends to use the pad to launch its upcoming Falcon Heavy rocket, which will be the most powerful American rocket since the Saturn V. The first test launch of the Falcon Heavy is expected to be near the end of 2015. If it does launch, it will beat NASA's own SLS rocket, also a heavy-lift vehicle, by a couple of years.  You can find out more about the Falcon Heavy here:

50 Years Ago: FIrst Lunar Test Vehicle Ready

LLRV in flight over Edwards AFB in 1965.

Back in 1964 on April 15, the NASA FLight Research Center received the first version of the LLRV (Lunar Landing Research Vehicle). Built by Bell Aerosystems Company, the cage-like vehicle operationally resembled the flight characteristics of the Apollo Lunar Excursion Module. On this machine, astronauts and test pilots would practice maneuvers that would be required to land the LEM on the Moon in future Apollo missions. The controls were adapted to function in Earth gravity, but feel to the pilot how engineers thought they would feel while simulating Lunar gravity. The vehicle was very unstable, and was considered one of the most dangerous craft a test pilot could ride. This was the first of two vehicles delivered.

A closer look at the LLRV. COl. Emil "Jack" Klueger was one of the test pilots who would learn to tame the beast.

50 Years Ago: Project Fire

Atlas D rocket lifting off with Project FIRE from Pad LC-12.

Fifty years ago, scientists designing the spacecraft for Project Apollo knew that the command module with three astronauts would be slamming into the Earth's atmosphere at over 25,000 mph. To understand the heat stresses on the craft's protective shield, they needed to actually plunge an object with sensors into the atmosphere at that speed and analyze the results. Project FIRE (Flight Investigation Reentry Environment) studied these effects for the various NASA spacecraft.  On April 14, 1964, NASA launched an Atlas D rocket carrying a Project Fire test object from LC12 into a 500 mile arc into space. Never intending to reach orbit, the craft separated and plunged down at a steep angle replicating the speed the Apollo capsule would be travelling. Sensors on board the experiment could then measure and define the stresses encountered and the heat effects.

To reach the incredible speed, as the object prepared to return to Earth, and Antares II motor ignited and pushed the experiment even faster. Lasting about 30 seconds, the eventual speed of about 26,000 mph was achieved. While cameras on the ground filmed the fiery descent the craft recorded heat on the exterior at about 20,000 degrees F. After 32 minutes from launch time, the craft impacted into the Atlantic Ocean.

50 Years Ago: Gemini-Titan 3 Crew Announced

Gemini-Titan 3 Prime and Backup crews: (L-R) Young, Grissom, Schirra, Stafford.

Fifty years ago, with the excitement of a successful test mission of the GT-1 unmanned vehicle just completed, NASA made official the names of the astronauts who would pilot the first manned mission in Project Gemini. The Prime crew would include veteran astronaut Gus Grissom and new astronaut John Young. The backup crew, who would launch in case of illness or injury to either of the prime crew before the flight, would be veteran astronaut Wally Schirra and new astronaut Tom Stafford.

Gus Grissom was the astronaut on board the Mercury space capsule Liberty Bell 7 when in arced over the Atlantic on the second flight in Project Mercury. His 15-minute sub-orbital flight was a success, but his spacecraft experienced a hatch jettison malfunction after landing in the water. With the capsule filling with water, Grissom was able to escape as Navy frogmen struggled to hook the craft to helicopter tow cables. Unfortunately the craft sank to the bottom of the Atlantic. After a review, Grissom was cleared from any mistakes and became one of NASA's top astronauts. He was previously a test pilot, and had flown 100 combat missions during the Korean War. He would be the first American to fly twice into space.

John Young, in Gemini-era spacesuit.

John Young graduated from Georgia Institute of Technology with a degree in Aeronautical Engineering. He served in the Navy during the Korean War and became a jet pilot afterwards. After tours of duty on aircraft carriers, he became a test pilot and finally joined NASA in Astronaut Group 2, known as the "New Nine." Young would have a very adventurous career with NASA, but his addition to the first Gemini flight came about because the original planned commander was Alan Shepherd, the first American in space, had suddenly come down with an ear and balance ailment which grounded him from flight. Tom Stafford had been planned as pilot, but with Shepherd's removal, the backup crew moved forward leaving Grissom as Commander and Young as Pilot. Wally Schirra then became the new backup crew commander working with Tom Stafford. Such is the life of a NASA astronaut.

50 Years Ago: Gemini Program FIrst Unmanned Launch

NASA published image of Gemini Launching atop a modified Titan II rocket. The Launch tower more closely resembles the familiar tower design we would see later with the Apollo program.

Between the end of the Mercury program and the start of launches for Project Gemini, there were lots of rockets tested, satellites put into space, and experiments conducted in the upper atmosphere and Earth orbit. Then 50 years ago on April 8th, the look and feel of the new Gemini program came to life as the twin engines on the Titan II rocket roared into action. With the exhaust plume directed under the pad and to the side, cameras had a clear view of the rocket flames as the vehicle lifted off and cleared the tower. Perched on top of the rocket was a mockup of the Gemini capsule (called the boilerplate) that gave us the view of how missions would look in future launches. In the future, two astronauts would ride the rocket and no American would go into space alone again. 

Before the launch. The gantry tower, which was used to help stack the stages of the rocket together with the capsule, lowered into a horizontal position to avoid damage from the blast-off. 

Designated mission GT-1 (Gemini-Titan 1), this test mission was designed to evaluate the entire Titan II launch vehicle system, and the Gemini spacecraft integrity and compatibility with the rocket. After a perfect countdown and liftoff, the rocket staged and placed not only the capsule but also the second stage into orbit about 204 miles at its highest. OK, maybe not perfect. The vehicle faster than expected placing the craft in orbit going 14 miles faster than planned. The orbit path was not meant to last a long time, and the assembly was calculated to re-enter the atmosphere in 3 and a half days.

The next day, Titan II ICBM testing at Florida came to an end. The 33rd and final rocket launch for the USAF made a successful trip out over the Atlantic, and the ICBM portion of Titan II Research and development was completed.

Atlas V Blast-off Restarts Florida Launches

Mission NROL-67 blasts off from SLC-41 in Cape Canaveral. All pics in this post are from ULA.

Yesterday at 1:45 PM EDT an Atlas V carrying a spy satellite lifted off without problems for an eastern flight across the Atlantic Ocean and up into geosynchronous orbit. With this successful launch, and no reported problems from the recently repaired Range radar, the launch schedule from Florida can resume. The next flight is on April 14, when SpaceX launches the Falcon rocket with its Dragon resupply spacecraft to the ISS.

Atlas V on pad SLC-41.

It was a beautiful day for a launch, and congratulations to the ULA (United Launch Alliance) team that has launched two Atlas V missions across the country from each other within about a week's time.

Ground view of the Atlas V.

Liftoff!

The Atlas V goes supersonic. The solid rocket boosters give a tremendous push.

With their fuel expended, the boosters are jettisoned and the rocket continues to climb using its core fuel. 

US Cargo Missions to ISS to Resume

SpaceX Falcon rocket with Dragon cargo spacecraft at Complex SLC-40. 

The main radar installation that supports launches from both the Kennedy Space Center and the Cape Canaveral Air Force Station suffered a fire a few weeks ago. It turns out that the radar, operated by the 45th Space Wing of Patrick Air Force Base, required major surgery to repair. As a consequence, launches scheduled from the east coast of Florida were delayed. Today that delay will end, hopefully, with the launch of an Atlas V carrying a classified military satellite. Following today's launch, SpaceX will be clear to launch its Dragon cargo spacecraft to the ISS on April 14th.

Atlas V launch last Thursday from Vandenberg AFB.

Today's Altas V launch was itself dependent on a successful launch of another Atlas V mission last week from Vandenberg AFB in California. That mission, carrying an Air Force weather satellite, started a 7 day turnaround for support crew elements and a review of the launch data. Once the data had been cleared, and the support crew from the United Launch Alliance (ULA) had transferred over to  Florida to work on the launch of the new updated Atlas V 541, which can launch heavier payloads than the earlier Atlas V versions. Today's mission carries a secret spy satellite for the National Reconnaissance Office. 

Progress spacecraft approaches the ISS.

In the meantime, the glitch that occurred on the recent Russian Soyuz launch to the ISS seems not to have repeated with the launch this week of a Progress robotic cargo spacecraft to the station. Using the navigational shortcut trajectory, the Progress M-23M (P55) spacecraft successfully arrived to dock with the station after a six hour flight on Wednesday April 9th. A previous Progress spacecraft, Progress M-22M (P54), undocked from the ISS on Monday. Filled with garbage and waste, the craft will remain in orbit for 11 days while engineers on the ground conduct some final experiments, then it will burn up in the atmosphere. The current Progress is docked at the Russian-built Pirs module.
