SpaceX’s Starship blew itself up in the air, Elon Musk’s private space company has said. Starship underwent its second flight test over the weekend, when the company attempted to send the rocket almost into orbit and then have it land in the ocean. It completed the first part of that mission – but disappeared around eight minutes into its flight. Now the company has confirmed that it lost data from the flight at that moment, which came near the end of the burn of the second stage of the rocket. At that point, the spacecraft used a “safe command destruct” that meant that it caused itself to explode in the air, the company said. It did not say why that had been issued, but did indicate that it had been “appropriately triggered based on available vehicle performance data”. SpaceX noted that until that moment the flight appeared to have been going as planned. The Super Heavy Booster on the bottom of the spacecraft completed a full burn for the first time, for instance, and the two pieces of Starship separated successfully. The booster also managed to flip after it had separated from the upper part of the rocket, SpaceX said. It started another burn then but then “experienced a rapid unscheduled disassembly”, as SpaceX refers to explosions. That came three and a half minutes into the flight and happened around 90 kilometres above the Gulf of Mexico, SpaceX said. The company said that the explosions would prove useful in adjusting future builds of the Starship spacecraft. Before the flight it had explicitly said that the launch was intended as a test and could go wrong – and it reiterated that “while it didn’t happen in a lab or on a test stand, it was absolutely a test”. “With a test like this, success comes from what we learn, and this flight test will help us improve Starship’s reliability as SpaceX seeks to make life multiplanetary,” SpaceX said. “Data review is ongoing as we look for improvements to make for the next flight. The team at Starbase is already working final preparations on the vehicles slated for use in Starship’s third flight test, with Ship and Booster static fires coming up next.” Read More SpaceX launches “limitless” ‘zero fuel’ engine into space SpaceX hints next Starship launch attempt could be soon SpaceX launches world’s most powerful rocket – and then it disappears

Nasa has received a signal from a spacecraft 10 million miles away. The message, delivered using a distant laser, could “transform” communications with spacecraft, the space agency has said. It represents a successful test of Nasa’s Deep Space Optical Communications or DSOC experiment. It is also the first time that data has been successfully relayed through a laser from further away than the Moon – and marks a rapid increase, at more than 40 times the distance from the lunar surface. At the moment, almost all communications with craft in deep space is achieved through radio signals, sent and received from vast antennas on Earth. They have proven reliable but their bandwidth is limited, meaning that it is slow or impossible to send large files such as high-definition photos and videos. Nasa’s work on DSOC is an attempt to use optical communications through lasers instead. The technology could improve data rates by as much as 100 times, the space agency says. The first attempt to test the technology beyond the Moon left the Earth on Nasa’s Psyche mission, which left Earth last month on a mission to study a distant asteroid. The spacecraft is carrying a laser transceiver than can both send and receive laser signals in near-infrared. Last week, that equipment locked onto a Nasa laser beacon in California. Nasa says that “first light” breakthrough is one part of a host of experiments that they hope will prove the laser technology can work. “Achieving first light is one of many critical DSOC milestones in the coming months, paving the way toward higher-data-rate communications capable of sending scientific information, high-definition imagery, and streaming video in support of humanity’s next giant leap: sending humans to Mars,” said Trudy Kortes, director of technology demonstrations for the Space Technology Mission Directorate at Nasa Headquarters in Washington. Nasa likens the precision pointing of the laser signal to trying to point a light at a coin from a mile away. What’s more, the laser and its target are constantly moving: in the 20 minutes it will take for the light to travel to Earth from Psyche’s furthest distance, both the planet and the spacecraft will have moved significantly. The team will now work to refine the systems that ensure the spacecraft is pointing its lasers in the right direction. When that happens, Nasa will try an experiment to demonstrate that the spacecraft is able to maintain high-bandwidth data transfer at different distances from Earth. It will do so by breaking the data into bits that can be encoded in the photons of light sent by the spacecraft. That light then arrives at the telescope on Earth and can be reassembled into images or other important data that will be sent by spacecraft – and perhaps humans – in the future.
