News From SpaceX: Falcon 9 Completes Second Test Flight

falcon-9-reusable-test2In yet another impressive feat from Elon Musk’s private space company, the Falcon 9 Reusable Rocket completed it’s second test on Friday April 2nd, 2014. In this latest test of the reusable rocket system, the Falcon 9 effectively quadrupled its height from its last test. Having reached 250 meters during its last test flight, the rocket now reached a full kilometer and then descended safely back to Earth and achieving a soft landing.

This comes just two weeks after SpaceX launched one of its Falcon 9’s on a supply mission to the ISS, which included the soft landing of its stage one rocket. Unfortunately, high sea waves prevented a boat from meeting the rocket on its ocean-based pad. And so, the rocket landed in the ocean, hovering for a few seconds before toppling into the sea. Still, the fact that the rocket was able to make it back to just above sea level was good news, and confirms that SpaceX is that much closer to the dream of reusability.

In addition to reaching higher altitudes, they will also be testing the rocket’s retractable landing legs, and working more with unpowered guidance. According to the description that came with the recently-released video of the 1000m test:

F9R test flights in New Mexico will allow us to test at higher altitudes than we are permitted for at our test site in Texas, to do more with unpowered guidance and to prove out landing cases that are more-flight like.

This is also good news for NASA, which officially announced the cessation of cooperation with the Russian Federal Space Agency in early April. While their inability to rely on Russian Soyuz rockets to send astronauts into orbit (and bring them home) has allowed NASA to apply greater pressure on the federal government to fund its Reusable Launch Vehicle (RLV) system. However, Russian Deputy Prime Minister Dmitry Rogozin had a more mocking suggestion.

The joke was naturally irrelevant, since day-to-day operations involving the ISS are not going to be affected by these sanctions. Still, the inability to rely on Russian Soyuz’s in the near future will mean that US satellites – which are used for everything from GPS to spying – will be undeployable for the time being.

It also means that orbit conducted in Low-Earth Orbit will be complicated. As such, a reusable rocket system, be it NASA’s own or an external contractor’s (in this case, SpaceX) will give the US sanctions against Russia additional weight. It will also ensure that the dream of cost-effective space travel, which is intrinsic to everything from colonizing the Moon and Mars to establishing a Space Elevator and asteroid mining, will be become a reality in the not-too-distant future.

The sky is no longer the limit, people! And be sure to enjoy this video of the F9R 1000 meter test flight.

News from SpaceX: Falcon 9 Reusable Rocket Test

falcon-9-reusable-test-640x353For over two years now, Elon Musk and his private space company (SpaceX) have been working towards the creation of a reusable rocket system. Known as the Falcon 9 Reusable Development Vehicle (F9R Dev) – or “Grasshopper” – this system  may prove to be the greatest development in space travel since the invention of the multistage rocket. After multiple tests that reached greater and greater altitudes, the latest attempt at a takeoff and soft landing took place this past month.

Timed to coincide with SpaceX’s launch to the International Space Station (which took place on Friday April, 18th) the landing was apparently a success. Several days after the launch, Elon Musk tweeted that the “[d]ata upload from tracking plane shows landing in Atlantic was good!” This update came on April 22nd, and as of yet, no definitive data of whether the first stage landed correctly, or whether it was still in one piece by the time the recovery boats got to it.

In the meantime, they took the opportunity to release a rather awesome video of what the Falcon 9 Reusable should look like when successfully performing a vertical takeoff and vertical landing (VTVL). The video has accumulated an astonishing 3,598,143 views in the last two weeks, which is indicative of the level of interest this project and its impications have garnered over the past few years.

Meanwhile, the resupply mission went off without a hitch. Officially designated as CRS-3, this mission was even more significant due to the fact that its Falcon 9 launch vehicle featured the same retractable landing legs and the ability to soft land as the Grasshopper test rocket. However, in the case of the ISS mission, it was the first time where a Falcon 9 was tested in a real-world scenario where the rocket would return to Earth after reaching Low Earth Orbit (LEO).

Though the rocket was successfully picked up by the ISS, the jury is still out on whether or not the soft landing was a success or not. To minimize any risk, the first stage of the Falcon 9 attempted to “soft land” in the Atlantic. Unfortunately, according to Elon Musk, due to “13- to 20-foot waves… It’s unlikely that the rocket was able to splash down successfully.” Using telemetry data gathered from a SpaceX spotter plane, it appears that everything else went to plan, though.

Because of the rough seas, though, the retrieval boats couldn’t make it to the landing site, and thus the rocket is unlikely to be recovered. In the meantime, SpaceX will spend the following days and weeks analyzing more detailed data from the launch, and then update the Falcon 9 design and launch protocol accordingly. However, it is clear at this point that these latest tests are not being considered a failure, or reason to cease in their efforts.

falcon-9-r-580x386As Musk himself explained in a series of public statements and interviews after the launch:

I would consider it a success in the sense that we were able to control the boost stage to a zero roll rate, which is previously what has destroyed the stage — an uncontrolled roll… I think we’re really starting to connect the dots of what’s needed [to bring the rocket back to the launch site]. I think that we’ve got a decent chance of bringing a stage back this year, which would be wonderful.

Considering the benefits of cheap, reusable rockets, and all the things they will make possible – space-based solar power, the construction of a Moon settlement, missions to Mars, the construction of a Space Elevator – there’s simply no way that a single unsuccessful rocket recovery will deter them. In the meantime, be sure to check out this video of what a successful Falcon 9 VTVL test looks like. Hopefully, we’ll be seeing a real-world example of this happening soon:
