A second attempt in February was scrubbed because of rough weather, but the Falcon first stage still managed a nice upright water splashdown. In January, the first attempt led to the Falcon first stage landing too hard on the drone ship platform and exploding. This is a video of the simulator in action. Box2D was the physics engine of choice and the environment is similar to the Lunar Lander. The simulation was developed in Python 3.5 and written using OpenAI's gym environment. Two previous attempts to return the reusable rocket have already faltered. This is a vertical rocket landing simulator modelled from SpaceX's Falcon 9 first stage rocket. It carried SpaceXs robotic Dragon cargo spacecraft, which is now on its way. EDT April 8 from Floridas Cape Canaveral Air Force Station. 2,885 3 23 36 A simple idea is to have a manned aircraft, or drone, sending the video to a ship nearby which has the satallite antenna on it. The idea is meant to work if the rocket stage can touch down with a landing accuracy of within 10 meters. The two-stage Falcon 9 rocket blasted off at 4:43 p.m. The rocket also has four hypersonic grid fins to help guide it in for pinpoint landings aboard a drone ship platform. SpaceX’s sped-up clip, shot on Saturday night from the deck of the company’s A Shortfall of Gravitas droneship, shows the 70-meter-tall (230 feet) Falcon 9 rocket lifting off in the far. SpaceX designed the Falcon’s first stage so that it could return safely to Earth it uses engine burns to slow its descent. This maneuver will make the Falcon 9 landing look like a walk in the park in comparison. The latest launch was delayed from its initial Monday 13 April time slot because of weather issues, but has been rescheduled for a second launch attempt around 4:10 PM EDT today. Another huge upgrade for Starship is its massive payload bay. SpaceX’s Falcon 9 is the workhorse of the commercial rocket fleet that has been launching supplies to the space station under NASA contract. The reusable rocket in question represents the first stage of a Falcon 9 heavy rocket. But the sixth SpaceX mission to resupply the International Space Station offers a new opportunity for the private spaceflight firm to once again test its potentially game-changing vision for cutting the costs of future space missions. One ended in flames, and the other culminated in a water splashdown. SpaceX has twice attempted to land a reusable rocket on a drone ship at sea. “Looks like Falcon landed fine, but excess lateral velocity caused it to tip over post landing,” Elon Musk tweeted. Update, 14 April: The third SpaceX attempt to land a reusable rocket on a drone ship came close to success, but not quite.
