![]() Well, it could happen as soon as Wednesday. "So when will this cursed thing launch?" you might've been asking. Thankfully, only minor repairs were necessary to get the rocket back into shape. But that decision jeopardized the launch timeline one more time because it meant Artemis I had to battle incredibly high winds it wasn't quite built to withstand. ![]() The rocket wasn't rolled off the launchpad this time. And then , as if Artemis I hadn't already been through enough, Hurricane Nicole blew in last week. ![]() The agency finally announced a new launch date of Nov. 2 because the storm forced NASA to roll the tangerine machine off the launchpad and back to safety in the Vehicle Assembly Building. Hurricane Ian even ruined the agency's backup launch date of Oct. The third attempt got nixed in late September as Hurricane Ian threatened Artemis I's launch site at Kennedy Space Center in Cape Canaveral, Florida. On the second attempt a few days later, a pesky hydrogen leak kept it grounded. NASA scrubbed the craft's first launch attempt in late August due to a troublesome engine issue. NASA's ambitious, expensive and intricate moon rocket, Artemis I, has had a rough run. What follows below is the original story. If the growth of this space junk continues unhindered, we risk losing the most useful and economically vital orbital pathways around Earth which are used by satellites like the International Space Station.NASA launched the Artemis I mission on Wednesday morning. However, we will have a talk by Ralph “Dinz” Dinsley as he explores the growth of space debris. The hectic schedule, featuring many vehicle arrivals and complex spacewalks, unfortunately made it impossible to arrange another link-up with this year’s New Scientist Live on 10-13 October. It is an exceptionally busy period for the ISS right now, with three new arrivals on 25 September bringing the head count up to nine. “Our ESA astronauts’ schedules are packed with science and technology experiments, ISS operations such as extravehicular activities and maintenance, so finding the slots is difficult,” he says. Courtenay Taylor can recall only one such mishap in the past 10 years.Ĭommunication and outreach is an important duty for astronauts, says Marco Trovatello at the European Astronaut Centre, but making time for link-ups like these is challenging. Remarkably, it is rare for the connection to fail. “That’s fine – everybody expects there to be a delay,” says Courtenay Taylor. The lag on the pictures at such events is around 5 to 6 seconds, as a result of three sets of satellite transmissions and a conversion between video standards between the US and Europe. Both are connected by fibre to the main NASA communications hub.įor events in Europe, NASA’s TV desk sends the pictures via a domestic satellite to Toronto, then via a transatlantic satellite to the venue. Signals from TDRS are received at two NASA facilities on Earth: one at White Sands, New Mexico, and one on Guam in the Pacific. The International Space Station orbits the Earth at an average distance of about 400 kilometres, and relies on geostationary satellites for communication with the ground. These have data rates similar to a home fibre internet connection. To maintain the data link, NASA has a small constellation of satellites, known as Tracking and Data Relay Satellites (TDRS), which enable near constant communication between the ground and orbiting satellites. Since the space station crosses the horizon every 4 minutes, it is impossible to track using ground stations. How does the International Space Station communicate with Earth? But setting up the video link and broadcasting live pictures from low Earth orbit is no easy feat. They don’t get to see pictures from the event. When NASA sets up a video link to Earth like at New Scientist Live, astronauts only get to hear the audio side of the call. The phone number at NASA Johnson Space Center is +1 28, but your chances of getting through to the ISS are slim. If someone does need to “call” the ISS, operators at mission control centres simply relay the audio through a telephone line to Houston into the very high frequency space-to-ground radio network. Phones on the ground cannot call them back, however.Īstronauts also have tablet computers that they can use to send emails, and although some do send tweets from orbit, these are normally emailed to their communications teams on the ground, who do the posting. For private calls, the space station has an internet-connected phone system that works through a computer, which astronauts can use to call any number on Earth. It has no phone number in the traditional sense, and astronauts have to leave their smartphones at home. ![]() Unfortunately, it isn’t possible to call, Skype or WhatsApp the ISS. Can you call the International Space Station? ![]()
