Masten Space Qualifies for Lunar Lander Challenge X-Prize

NOTE: Cross-posted to the Blog at Getting There From Here.

Congratulations to Masten Space Systems on successfully completing their qualifying flight for the $1 million prize in the Northrop Grumman Lunar Lander Challenge X-Prize. They join Armadillo Aerospace in qualifying for this prize.

To qualify, both companies had to demonstrate control of their vehicle by flying to an altitude of more than 50 meters, flying laterally for 100 meters, and landing on a simulated lunar surface complete with craters and boulders. After doing so, they vehicle had to take off from the simulated lunar surface and return to its starting point (with the option of refueling the vehicle between flights). And, oh yeah, they had to complete all of this (including any necessary refueling) in less than two-and-a-half hours.

Another team, Unreasonable Rocket, will attempt to complete their qualification tomorrow. BonNovA had intended to compete but had to withdraw.

We at Getting There From Here are huge fans of these types of competitions, as they allow a small amount of money to go a long, long way. In this case, the $2 million total prize money for the Lunar Lander Challenge has generated more than $20 million in research on rockets and helped at least a couple of small, entrepreneurial rocket companies to literally get off the ground. Kudos to the X Prize Foundation and Northrop Grumman for organizing and funding such a great contest.

Orion First Launch Date Slips One Year

As part of the government's Vision for Space Exploration (VSE), NASA had proposed to create a new launch system called Orion to enter use by 2015 as part of the Constellation program. Whatever you may think of Orion (and there are plenty of detractors) this is the launch system that—for better or worse—NASA will be using post-shuttle. With the space shuttle retiring in 2010 (or 2011, depending on Congressional priorities and willingness to take risks with a 30+ year old launch system) there will be a gap in the United States' ability to launch astronauts into orbit until Orion is available.

The deadline in the VSE for Orion's first launch is March 2015, but NASA always thought they could get it done a little earlier, possibly as early as 2013, in an attempt to shorten the gap in launch capabilities. Unfortunately, their hopes have now slipped to September of 2014 as the earliest possible launch date for Orion due to insufficient funding from Congress.

My opinion, though, is that NASA won't hit that September 2014 date, or even the Congressionally-mandated March 2015 date due to the amount of work still to be done and the uncertainties that crop up along the way. A while back it was revealed that the Orion launcher has problems with vibrations that could possibly shake the astronauts to death. The solution they came up with involved—get this—using springs to dampen the vibration. That's right, it took them six months to come up with the idea of using the same technology that your car uses to reduce the amount by which you feel bumps in the road.

The bureaucratic nightmare that is the U.S. government takes six months to put springs under the astronauts' seats... figuring out the complicated parts of a launch system (and testing it until it works reliably) will likely take considerably longer.

Third Falcon 1 Fails To Reach Orbit

Yesterday, SpaceX attempted to launch a Falcon 1 rocket into orbit for the third time (I blogged about one of the payloads here). Unfortunately, they also failed for the third time, this time due to the failure of the two stages to properly separate.

Elon Musk, CEO of SpaceX, issued the following statement:
It was obviously a big disappointment not to reach orbit on this flight [Falcon 1, Flight 3]. On the plus side, the flight of our first stage, with the new Merlin 1C engine that will be used in Falcon 9, was picture perfect. Unfortunately, a problem occurred with stage separation, causing the stages to be held together. This is under investigation and I will send out a note as soon as we understand exactly what happened.

The most important message I’d like to send right now is that SpaceX will not skip a beat in execution going forward. We have flight four of Falcon 1 almost ready for flight and flight five right behind that. I have also given the go ahead to begin fabrication of flight six. Falcon 9 development will also continue unabated, taking into account the lessons learned with Falcon 1. We have made great progress this past week with the successful nine engine firing.

As a precautionary measure to guard against the possibility of flight 3 not reaching orbit, SpaceX recently accepted a significant investment. Combined with our existing cash reserves, that ensures we will have more than sufficient funding on hand to continue launching Falcon 1 and develop Falcon 9 and Dragon. There should be absolutely zero question that SpaceX will prevail in reaching orbit and demonstrating reliable space transport. For my part, I will never give up and I mean never.

Thanks for your hard work and now on to flight four.

Falcon 1 to Launch Solar Sail

The next few days should be pretty exciting for advocates of space exploration. SpaceX's launch window for their 3rd Falcon 1 launch starts tomorrow (Aug. 1) and ends on the 5th. If this launch is successful, it will be the first time SpaceX has successfully put a payload into orbit aboard its low-cost Falcon 1 rocket, potentially ushering in a new era of less-costly space launches.

Not only that, the rocket will be delivering several payloads to orbit, but one of the most exciting (for space exploration advocates) is NASA's NanoSail-D, a 100-square foot solar sail created by NASA in just six months. Solar sails are an exciting technology, because they could allow spacecraft to accelerate without the need for on-board fuel, which greatly increases the costs. Also, fuel is the number one limiting factor in space travel, because the more fuel a spacecraft carries, the more mass it has, and the more mass it has, the more fuel it takes to move it. Every kilogram of fuel added provides less total thrust than the kilogram before it, so a system that can reduce or eliminate the amount of fuel needed could allow spacecraft to function further and longer.

Wikipedia has a pretty good page about solar sails.

I'm curious as to how well the NanoSail-D experiment will work, as Falcon 1 is not designed to lift payloads into high orbits. Lower orbits have increased drag, which is especially bad for solar sails given their surface area and the limited amount of pressure they receive from the solar wind.

You can watch the launch by going to the SpaceX website.

Endeavour Launches Tonight

Space Shuttle Endeavour launches tonight or early tomorrow morning, depending on what time zone you live in. The launch is scheduled for 2:28 AM EDT (1:28 AM here in the Central time zone) which means this will be the first launch in quite a while I have not watched live online.

This is a major mission, the longest duration flight to the ISS so far at 16 days. Over the course of the mission, the Japanese Kibo laboratory module will be added to the space station, along with a newer, improved robotic arm system (with two arms and fine manipulator "hands") from the Canadian Space Agency.

Additionally, Endeavour will be delivering Garrett Reisman for a stay aboard the ISS as part of Expedition 16 and will bring European astronaut Leopold Eyharts home from the space station.

Forecasters are projecting a ninety percent chance of good weather, and no problems have been indicated as of now, nine hours before the launch.

Atlantis Reaches Space

The weather turned out to be benign (at least at Cape Canaveral) and the fuel sensors worked successfully, allowing Atlantis to launch on-time at 2:45 PM EST. The shuttle reached space several minutes later and is on its way to the International Space Station carrying the Columbus science laboratory (Europe's single largest contribution to the station).

Columbus is about 23 feet long and 15 feet wide, allowing it to hold 10 "racks" of experiments, each approximately the size of a phone booth. Five NASA racks will be added to the laboratory once it is in orbit. Each rack provides independent controls for power and cooling, as well as communication links to earthbound controllers and researchers. These links will allow scientists all over Europe to participate in their own experiments in space from several user centers and, in some cases, even from their own work locations.

Atlantis Passes Fuel Sensor Checks; to Launch at 2:45 PM EST

Space Shuttle Atlantis passed all checks on the low-fuel sensors that failed in December, prompting NASA's two-month delay. The shuttle is due to launch in just a few minutes, at 2:45 PM EST, if the weather holds.

Launch Postponed

12/17/2007 - 9:28 AM - UPDATE: In order to give their staff some time off over the holidays, NASA has pushed the shuttle's launch date back again, this time to January 10. If they dalay much longer, the launch of Atlantis could impact the timeline for 2008's remaining shuttle launches. NASA has a pretty limited lifespan for these shuttles, which are supposed to be retired by 2010, so any delay in launching missions this year could have serious repercussions.

12/10/2007 - 8:11 AM - UPDATE: Still unable to find and correct the fuel sensor glitch, NASA has decided to postpone the launch until January 2, 2008. Doing so will hopefully give their people time to figure out why the sensors are failing (or replace them with a different set that will hopefully work better).

12/08/2007 10:26 AM - UPDATE: NASA has added a further delay, but odds are looking pretty good for a launch tomorrow. These sensors are a four-piece backup system, and when they fueled the shuttle on Thursday only two of the four registered. NASA's rules call for at least three to be functioning in order to launch, but they may relax that rule. They are also planning to shorten their launch window from the normal five minutes to just one minute to conserve a little extra fuel. The reason is that the sensors in question are designed to shut off the engines after fuel gets pretty low, and this way if they fail to shut off there will be a little bit more fuel left at the end of the burn.

12/07/2007 8:09 AM - UPDATE: It's not going to be today, either. NASA is going to spend a little time trying to figure out how to fix the wiring to the sensors. If they can't come up with a solution quickly, they may just launch tomorrow, anyway. These sensors are redundant systems, so not having them won't impact the launch unless the primary systems fail.

So the weather was perfect, but the shuttle wasn't. Two of four low-level fuel sensors on the Atlantis' external fuel tank malfunctioned, prompting a delay of at least 24 hours. Hopefully they'll get things fixed and launch the shuttle tomorrow.

Discovery Beats the Odds

Despite predictions of bad weather threatening the launch, the space shuttle Discovery made NASA's first night launch in four years tonight, rocketing off the launch pad at the Kennedy Space Center in Cape Canaveral, Florida.

This launch is one of fourteen remaining launches for the space shuttle fleet, thirteen of which will focus on completing assembly of the International Space Station. The remaining flight, in 2008, will be the final servicing mission for the Hubble Space Telescope.

In addition to supplies and a new piece of the space station, Discovery is delivering a new crew member to ISS, American Suni Williams, and returning German astronaut Thomas Reiter.

No Joy for Discovery

Last night's launch of the Discovery space shuttle was scrubbed due to poor weather, as expected. Since NASA has no expectation for better results today, the next attempt will be Saturday at 8:47 PM EST.

Discovery Launch Unlikely Tonight

NASA's first night-time shuttle launch in four years appears to be in jeopardy due to weather concerns. There is only a 40% chance of decent weather at the launch site this evening. Tomorrow night, the forecast is even worse, with only a 30% chance of acceptable weather, and then the forecast goes back to 40% for Saturday night.

Additionally, the weather forecasts for the emergency landing sites in Spain and France are pretty poor. Even if the weather is pristine in Florida, NASA won't launch the shuttle unless there is clear weather at at least one of the emergency landing sites.

My guess would be Saturday for Discovery's launch, but that's just a guess.

The purpose of this launch is to ferry supplies to the International Space Station, add another truss segment, and re-wire some of the station's power grid.
