+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! is the only website that has a public DB of satellite observations where you can search for flare reports

31/10/2014 - The Orbital Sciences Corporation, that built and launched Antares supply rocket crashed in Virginia, may replace the spacecraft's current AJ-26 Russian rocket engine, once their investigation of the crash is finalized, the company's CEO David Thompson stated. "Orbital has been reviewing alternatives since the middle of last year and recently selected a different main propulsion system for future use by Antares," Thompson said during a press conference Wednesday. "It is possible that we may d ... (source: - more...)

29/10/2014 - In what is proving to be a dramatic week for space flight, United Launch Alliance’s Atlas V rocket made its fiftieth flight on Wednesday, tasked with orbiting the GPS IIF-8 satellite for the US Air Force. Liftoff from SLC-41 at Cape Canaveral was on schedule at the start of an eighteen minute window that opened at 13:21 local time (17:21 UTC). (source: - more...)

29/10/2014 - An unmanned rocket owned by Orbital Sciences Corporation exploded Tuesday in a giant fireball and plummeted back to Earth just seconds after launch on what was to be a resupply mission to the International Space Station. "The Antares rocket suffered an accident shortly after lift-off," NASA mission control in Houston said, describing the blast at Wallops Island, Virginia, as a "catastrophic anomaly." Orbital's unmanned Cygnus cargo ship was carrying 5,000 pounds (2,200 kilograms) of supplies for the six astronauts living at the research outpost. (source: - more...)

29/10/2014 - A Russian Soyuz 2-1A rocket has lofted the latest Progress resupply vehicle (M-25M) en route for a fast rendezvous trip to the International Space Station (ISS). The launch of the Progress – riding on a Soyuz 2-1A for the first time – occurred at 07:09 GMT on Wednesday from the Baikonur Cosmodrome in Kazakhstan, ahead of a six hour trip to the orbital outpost.

27/10/2014 - Orbital Sciences postponed its planned launch of the Cygnus cargo ship toward the International Space Station on Monday due to a boat in the waters near the Virginia launch pad. "Tonight's launch of the Antares rocket carrying the Cygnus cargo craft has been scrubbed," a NASA commentator said on the US space agency's live broadcast. The boat was located inside the rocket's designated safety range, just to the southeast, and Orbital decided it was too risky to send the rocket soaring overhead. ... (source: - more...)

27/10/2014 - The Chinese have launched what appears to be the final satellite of the Shijian-11 series. Shijian 11-08 was launched at 06:59UTC on October 27, 2014, using a Long March-2C launch vehicle. The launch took place from the Jiuquan Satellite Launch Center’s LC43/603 launch complex.

26/10/2014 - China's spacecraft testing technology for the Chang'e-5 return lunar mission, trimmed its orbit on Friday afternoon. This was the first modification during a journey scheduled to take about eight days, according to a statement from the State Administration of Science, Technology and Industry for National Defense. The modification was necessary because the unmanned spacecraft is affected by external factors during the transfer from a terrestrial orbit to a lunar orbit, according to the statem ...

23/10/2014 - The Chinese have launched the third phase of its lunar exploration program on Thursday. Launch of the Chang e-5-T1 mission took place at 1800UTC, utilizing a Long March-3C/G2 launch vehicle from the LC2 launch complex of the Xichang Satellite Launch Center, Sichuan Province. The mission is aimed at testing the technologies that are vital for the success of the future Chang’e-5 sample return probe. (source: - more...)

22/10/2014 - Following two successful US EVA that, among other tasks, saw the failed ammonia Pump Module relocation and Sequential Shunt Unit (SSU) changeout, the Russian members of the Expedition 41 crew will take their turn in stepping outside into the vacuum of space, removing and jettisoning unneeded hardware and decommissioned experiments in the final EVA of 2014.

20/10/2014 - The longest-lived robot ever sent to Mars came through its latest challenge in good health, reporting home on schedule after sheltering behind Mars from possible comet dust. NASA's Mars Odyssey was out of communications with Earth, as planned, while conducting observations of comet C/2013 A1 Siding Spring on Sunday, Oct. 19, as the comet flew near Mars. The comet sped within about 88,000 miles (139,500 kilometers) of Mars, equivalent to about one-third of the distance between Earth and Earth's moo ... (source: - more...)

17/10/2014 - A top secret US robot space plane landed back on Earth on Friday after a 22-month orbit, officials said, although the craft's mission remains shrouded in mystery.
