SpaceX’s "autonomous spaceport drone ship" measures 300 by 170 feet (91 by 52 meters) with its "wings" extended.Image: SpaceX SpaceX will attempt one of the boldest maneuvers in the history of rocketry early Tuesday morning (Jan. 6) during a supply mission to the International Space Station for NASA, and you can watch the attempt live online. The California-based private spaceflight company will try to land the first stage of its Falcon 9 rocket on a floating platform in the Atlantic Ocean, shortly after the booster launches SpaceX’s robotic Dragon cargo capsule from Cape Canaveral Air Force Station in Florida at 6:20 a.m. ET Tuesday. NASA officials have said there is a 60% chance of good launch weather for the planned launch. You can watch the SpaceX launch live on Space.com, courtesy of NASA TV, beginning at 5 a.m. EST (1000 GMT). “The odds of success are not great — perhaps 50% at best,” SpaceX representatives wrote of the platform landing in a mission update last month. “However, this test represents the first in a series of similar tests that will ultimately deliver a fully reusable Falcon 9 first stage.” SpaceX will offer its own launch webcast on the company’s website beginning at 6 a.m. ET). Developing a fully and rapidly reusable rocket is a key priority for SpaceX and its billionaire founder, Elon Musk, who has said that such technology could cut the cost of spaceflight by a factor of 100. SpaceX has made strides toward this ambitious goal already. For example, the company successfully brought a Falcon 9 first stage down for a soft ocean splashdown twice last year — once in April and again in July. But Tuesday’s test will be much more challenging. The drone ship measures just 300 feet long by 170 feet wide (91 by 52 meters) with its “wings” extended, and the 14-story-tall Falcon 9’s leg span is about 70 feet (21 m), SpaceX representatives said. “During previous attempts, we could only expect a landing accuracy of within 10 km [6 miles],” they wrote in the update. “For this attempt, we’re targeting a landing accuracy of within 10 meters [33 feet].” Furthermore, although the drone ship will be equipped with position-stabilizing thrusters, it will not be anchored. Three separate engine burns will help get the rocket stage on course and slow its speed from 2,900 mph (4,600 km/h) down to 4.5 mph (7.2 km/h) at the time of touchdown. The landing legs will deploy during the final burn, company representatives said. SpaceX has also outfitted the Falcon 9 stage with four independently steerable “hypersonic grid fins,” which will be deployed upon atmospheric re-entry to aid in precision targeting. As bold as Tuesday’s test is, SpaceX has even more ambitious goals in mind for 2015. “Over the next year, SpaceX has at least a dozen launches planned, with a number of additional testing opportunities,” company representatives wrote. “Given what we know today, we believe it is quite likely that with one of those flights, we […]
Private spaceflight company SpaceX has been testing its Grasshopper rocket over the past few months, but it set a record last week with its latest launch in which it flew 2,440.94 feet in the air — the vehicle’s highest leap yet. Using a single camera hexacopter drone, SpaceX was able to get closer than ever to record the video above, which the company released Monday. As the rocket climbed gracefully into the air, the drone camera — which you can see in the right-hand corner of the frame — adjusted to capture the seemingly slow launch. Grasshopper soared in an almost-perfect straight line — quite different from its August launch, when it leapt sideways. The 10-story-high Grasshopper is one of SpaceX’s most outside-the-box experiments. Most rockets burn up when reentering Earth’s atmosphere, but Grasshopper is a reusable Vertical Takeoff Vertical Landing (VTVL) vehicle built to withstand these harsh conditions and return to the planet’s surface intact. Grasshopper holds the first-stage tank of the Falcon 9 rocket, which boosts SpaceX’s unmanned Dragon capsule to the International Space Station.
