+Flare Predictions
In this page you can track in real time all the satellites orbiting the Earth, with both 2D and 3D interactive representations, predict their passes, view their trajectory among stars on an interactive sky chart, predict satellite flares and transits (across the Sun and the Moon), find out the best location to see these events on a detailed Google map. You can also follow satellite re-entries and other special events, join the observer community, post messages and share your comments and observations. Currently in our database we have more than 9000 observation reports!. You won't find any other tracker that provides all these functions!

Read Observers' Reports! SatFlare.com is the only website that has a public DB of satellite observations where you can search for flare reports

Do you want to observe the International Space Station crossing your sky?
Install our 3D tracker for Android devices and you have just to point your phone to the sky and follow the line to find the ISS. You can also track the Station 24 hours a day with a 3D view of the Earth, constellations and more than 15.000 stars. A simple count down will inform you when you can actually see the ISS with the naked eye. Visit this web page for more details or for downloading the App.

News from Space and Spaceflights

16/09/2014 - Boeing and SpaceX will build the next generation of spacecraft that will carry US astronauts to the International Space Station (ISS), NASA said Tuesday, hailing a new chapter in space flight. The $6.8-billion contract announced by NASA administrator Charles Bolden at the Kennedy Space Center in Florida will enable the United States to develop its own crew transport vehicles that could carry astronauts to the ISS within the next three years, US officials said. "Today, with the selection of Boein ... (source: spacedaily.com - more...)

16/09/2014 - United Launch Alliance will launch an Atlas V rocket Tuesday evening, carrying into orbit a classified payload called CLIO for an undisclosed agency of the United States government. The launch is scheduled for a two-hour, 26-minute window opening at 17:44 local time (21:44 UTC) and closing at 20:10 (00:10 UTC). (source: nasaspaceflight.com - more...)

16/09/2014 - Astronauts from around the world have expressed interest in China's future space lab and station, hoping to cooperate with their Chinese counterparts on the Tiangong space station. Meeting in Beijing for the 27th annual meeting of the non-governmental Association of Space Explorers (ASE), astronauts from Russia, the United States and other countries visited Beijing Space Flight City, one of China's major space science and technology facilities. Dumitru Prunariu, president of ASE and Romania' ... (source: spacedaily.com - more...)

12/09/2014 - China has finished building of its fourth and most advanced space launch center, a senior space official said. Yang Liwei, deputy director of the China Manned Space Agency, said in Beijing on Wednesday that infrastructure construction on the Wenchang Satellite Launch Center in the southern island province of Hainan has been completed and that the station will soon become operational. "The center is basically ready for spacecraft launches," he said. Yang also said the nation's space pro ... (source: spacedaily.com - more...)

11/09/2014 - An Ariane 5 ECA has successfully launched two telecommunication satellites on Thursday. Optus 10 and MEASAT-3b both rode uphill on the Arianespace workhorse out of the European Spaceport in Kourou, French Guiana, following lift off late in the launch window – due to two technical holds – at 22:05 GMT.

10/09/2014 - A team of scientists led by Carnegie's Jacqueline Faherty has discovered the first evidence of water ice clouds on an object outside of our own Solar System. Water ice clouds exist on our own gas giant planets--Jupiter, Saturn, Uranus, and Neptune--but have not been seen outside of the planets orbiting our Sun until now. Their findings are published by The Astrophysical Journal Letters. At the Las Campanas Observatory in Chile, Faherty, along with a team including Carnegie's Andrew Monson, used th ...

08/09/2014 - A clandestine satellite launched on top of a Long March 4B rocket Monday to collect intelligence for the Chinese government. The Yaogan 21 satellite lifted off at 0322 GMT Monday (11:22 p.m. EDT Sunday) from the Taiyuan space center in northern China's Shanxi province, according to the state-run Xinhua news agency. Liftoff was at 11:22 a.m. Beijing time. The Long March 4B launcher also carried a secondary payload named Tiantuo 2 designed and built by the National University of Defense, Xinhua reported.

08/09/2014 - Nicaragua’s government said Sunday that a loud boom heard overnight by residents of the capital was made by a small meteorite that left a crater in a wooded area near the city’s airport. The crater left by the meteorite had a radius of 12 meters (39 feet) and a depth of 5 meters (16 feet). It is still not clear if the meteorite disintegrated or was buried. Humberto Garcia, of the Astronomy Center at the National Autonomous University of Nicaragua, said the meteorite could be related to an asteroid that was forecast to pass by the planet Saturday night.

06/09/2014 - SpaceX has conducted its second mission for China’s Asia Satellite Telecommunications Company Sunday, with a Falcon 9 launching the AsiaSat-6 satellite into a geosynchronous transfer orbit. Liftoff occurred at 01:00 local time (05:00 UTC) from the Cape Canaveral Air Force Station, ten minutes into a 104 minute window. (source: nasaspaceflight.com - more...)

05/09/2014 - A MicroMeteoroid and Orbital Debris (MMOD) strike on the Number 2 window of the International Space Station’s Cupola module appears to be contained within the debris pane, following evaluations by teams on the ground. The small, yet visible, damage to the window is not expected to impact on the operation of the Cupola – the Station’s main observation area and one of the star additions to the orbital outpost.

05/09/2014 - Later this year, China will launch a spacecraft to the Moon and back. A scale replica of the Shenzhou astronaut capsule will be carried atop a boxy spacecraft based on the Chang'e lunar orbiter, and launched by a Long March 3C rocket. The mission was originally expected to simply fly around the Moon on a "free-return" trajectory, but recent reports in China's state-run media claim that the spacecraft will actually enter orbit around the Moon. Then the spacecraft will fly back to Earth, and the She ... (source: spacedaily.com - more...)

03/09/2014 - The Chinese have launched a Long March 2D rocket on Thursday morning, lofting the Chuangxin 1-04 and the experimental Ling Qiao satellites into orbit. Launch occurred at 00:15 UTC from the LC43/603 launch complex of the Jiuquan Satellite Launch Center. As is the growing tradition with launches out of China, little information was released about the mission. (source: nasaspaceflight.com - more...)
