Yes, it’s been twelve months since my last post. So, I thought I’d give a quick run down of spaceflight activities for the past year. It’s been a busy one with many exciting developments.
Let’s start with the ISS’s growth spurt. The installation of ESA’s Columbus module, and JAXA’s Kibo Pressurized Logistics Module, and NASA’s Node 2 Harmony greatly expanded that habitable volume of the orbital outpost. It also means that. ESA and JAXA activated their own control rooms to support their modules. ESA also wins bonus points for finally getting Jules Vern, their first ATV cargo ship off the ground last month. After several rendezvous tests, the unmanned vehicle automatically docked to a Russian port. Just the other day, Jules Vern fired two of its four engines to boost the Space Station’s orbit.
Canada also has new hardware on orbit. Dexter, a two-armed extension for the Canada Arm II, accompanied the Kibo module on STS-123. It’s designed to complete some of the maintenance and repair tasks usually handle by space walking astronauts. Considering how dangerous those activities are, Dexter is a welcome contribution to this great experiment in space.
The ISS also played host to numerous international astronauts. Germany’s Hans Schlegel helped install ESA’s Columbus module on STS-122. Frances’s Leopold Eyharts also rode up on STS-122 and remained on orbit for a month to configure Columbus before returning on STS-123. Japan’s Takao Doi flew aboard STS-123 to deliver and install the Kibo PLM. South Korea also sent its first astronaut into space. Engineer Yi So Yeon joined Russia’s most recent Soyuz taxi flight. She spent ten days on orbit, and introduced the crew to some Korean foods including spicy kimchi, and fermented soybean paste. Both of which I can personally confirm are delicious, as I currently reside just north of Seoul. Soon the ISS may boast both an international cuisine as well as an international crew.
In other news, NASA’s project Orion is proceeding. The mockup capsule for the launch abort test is complete. Orbital Sciences is building the abort tower that will cap the module. Launch pad modifications are under way for the Ares I-X test. The dummy upper stage for the test is also complete. NASA also conducted numerous airbag tests to see if the vehicle can safely perform a landing on dry ground. They performed drop tests for the larger parachutes needed for the extended five segment solid booster. It’s great to see real hardware under construction and in tests.
The private sector hasn’t been sitting on its laurels either. Bigelow Aerospace successfully launched Genesis II, and is pushing forward with plans for full-scale inflatable orbital modules.
Armadillo Aerospace again failed to capture the Lunar Lander Challenge at the XPrize Cup. However, they were the only team to field a vehicle, and their repeat attempts were the highlight of the Cup. They also posses an experimental launch permit which has allowed them to log a great deal of low altitude flight time beyond tethered flights. They also have a modular sub-orbital design, which looks like it could be a commercial success.
SpaceX still hasn’t orbited any hardware, but progress continues on the Falcon 1 and Falcon 9. Flights of both are still scheduled for this year, and the company has plenty of paying customers lined up. They’ve improved their Merlin engine with a regeneratively cooled version that increases the available thrust, and their engine test stand has been keeping their neighbors on their toes. SpaceX is still on track for the COTS program, and has past several critical reviews and funding milestones. NASA also awarded them an indefinite quantity, indefinite time contract for launch services to be specified as needed.
Scaled Composites/ The Spaceship Company has had the roughest year. They had an engine blow up on a test stand. The accident resulted in two deaths, and has slowed down development work on SpaceShip II. Burt Rutan is in it for the long haul, and is an experienced aircraft designer. They will investigate the causes of the accident, and prevent it from occurring again. This will not end the SpaceShip II program. One interesting idea to come out of Virgin Galactic is that this model could be used for point to point supersonic flights as well as space tourism.
One last note: NASA finally managed to get rid of Rocket Plane Kistler and re-award their portion of the COTS contract to Orbital Sciences. RPK failed to make required funding deadlines. Few space insiders really believed RPK had the muscle to launch any hardware into space. Their K-1 vehicle has been “90% complete” for the past five years, and they haven’t done anything in that time but burn money. Orbital Sciences was a new aerospace startup during the Reagan administration. They still think like a small, young organization, but they have a successful development track record including three launch vehicles.

2006 was a pretty good year in space. The international launch community averaged over one orbital launch per week. U.S. and Russian providers carried out the bulk of the operations but the E.U., Japan, Israel and China also had successes under their belts. With four failed launch attempts, the failure rate was a mere 6%, which is considerably better than the historical average of 10%.
Manned spaceflight had a banner year. The International Space Station returned to a three-person crew and played host to astronauts and cosmonauts from the U.S., Russia, Germany, Sweden, and Japan. Although U.S. citizens, Astronauts born in Australia and England also visited the ISS and truly put the “International” in the International Space Station. Anousheh Ansari, perhaps the most famous space tourist to date, traveled to the station on one of two Soyuz flights this year. Her blog carried many dreamers with her on the ten-day journey.
NASA also managed to conduct two ISS construction flights. Space walkers and the robotic arm installed the P4 solar arrays, the P5 spacer truss, and rewired the electrical system to its permanent configuration. For the first time several years, the ISS actually looks different from the outside. Not only that, the increased power supplied by the new photovoltaic cells sets the stage for the installation of Japanese and European modules over the course of the next two years.
The emerging aerospace companies had more of a mixed year. SpaceX attempted to launch a partly reusable Falcon 1 at the start of the year, but suffered a major engine failure. Even with the loss of the vehicle, NASA still awarded them $278 million to develop cargo delivery and possibly human taxi services to the ISS. Rocketplane-Kistler won the other COTS development contract for $207 million to develop the same services.
UP Aerospace and Armadillo Aerospace both struggled with suborbital flights. UP Aerospace lost their launcher the New Mexico’s innaugerral spaceport flight, when it veered off course and disappeared into the White Sands Missile Range. It took them over a week to recover the broken hardware so they could analyze the failure.
Armadillo conducted several spectacular flights at the X Prize Cup in October. In an attempt to secure the Lunar Lander Challenge, a golf cart sized LH/LOX rocket vehicle named Pixel had to traverse 100 feet, land, and then return to its launch pad. The team made three tries at the event, and accomplished the first half of the challenge, but suffered equipment malfunctions and other difficulties at the landing site. If their vehicle had been a bit more robust, they certainly would have succeeded.
Bigelow Aerospace impressed most space watchers with the launch of their first test of an inflatable orbital habitat. The subscale vehicle was launched on a Russian Dnepr rocket and surpassed expectations. The inflation was flawless, and the mini-space station established contact with Beigelow’s ground station. The on-board thrusters stabilized the initial tumbling, and the solar cells fed power to the systems. Video cameras mounted inside and outside let the world witness this privately funded success.
In the next installment we’ll take a look at the accomplishments of our unmanned explorers over 2006.
Space Flight Is Still Challenging September 26, 2006

Today, both UP Aerospace and Rocketplane Kistler suffered serious setbacks. Though one was technical and the other financial and administrative, the both demonstrate that even suborbital space flights are not easy. UP Aerospace’s Spaceloft XL attempted it’s maiden flight, but the vehicle was lost after 13 minutes of flight. The solid fueled unmanned rocket was also the first launch at New Mexico’s new spaceport. The vehicle never made it to its intended altitude, and the exact nature of the malfunction is still unknown.
Rocketplane Kistler suffered a different kind of malfunction. Last month NASA awarded them $207 to fund their ISS resupply demonstrator as part of the COTS program. This should have made it easier for Kistler to secure the rest of the funding needed to complete the K-1 rocket. Unfortunately, their prime contractor, Orbital Sciences pulled out citing disagreements over Kistler’s business plan. Orbital also withdrew the $10 million they had promised to invest in the project. Almost as importantly, Rocketplane Kistler will loose the legitimacy brought by working with an established aerospace firm like Orbital Sciences.
With the high cost of spaceflight, a single setback like this can be devastating for a startup. President Reagan’s administration also attempted to encourage the development of private space flight. Out of all the startups that sprang into being, only one managed a launch during his presidency. The Conestoga was the nation’s first privately funded launch vehicle. Instead of leading to an era of private space launch, it exploded, causing investors to flee the industry. There was no second launch attempt for the Conestoga. Only one startup from that era is still in the launch business today. Orbital Sciences, and their Pegasus rocket have a proven track record for small payloads.
Hopefully, today’s aerospace startups will prove a bit more resilient. They’ll have to be if they want to succeed. The average launch failure rate around the world is still one in ten. This means that everyone who wants to launch rockets must expect launch failures during and even after development. In March, SpaceX, the other COTS contract recipient, suffered a technical malfunction on the maiden flight of their Falcon 1. Interestingly, NASA selected them after this failure. At least one investor has appears to have the guts it takes to stomach rocket development pains. Perhaps the industry will maintain a stronger base of support this time around.
