+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

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.

20/10/2014 - The Chinese have launched another new satellite in the military’s Yaogan Weixing series via the use of a Long March-4C (Chang Zheng-4C) rocket. The mission began with lift off at 06:31 UTC on Monday from the LC901 launch platform of the LC9 launch complex at the Taiyuan Satellite Launch Center. (source: - more...)

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. The unmanned X-37B, which looks like a miniature space shuttle, glided into the Vandenberg Air Force Base in California after having launched on December 11, 2012, on a mission that military officers say is still strictly secret. "I'm extremely proud of our team for coming together to execute this third safe and successful landing, sai ... (source: - more...)

17/10/2014 - Astronomers using the National Science Foundation's Green Bank Telescope (GBT) in West Virginia, along with data from other large radio telescopes, have discovered that our nearest galactic neighbors, the dwarf spheroidal galaxies, are devoid of star-forming gas, and that our Milky Way Galaxy is to blame. These new radio observations, which are the highest sensitivity of their kind ever undertaken, reveal that within a well-defined boundary around our Galaxy, dwarf galaxies are completely devoid o ...

16/10/2014 - An Ariane 5 ECA returned to action on Thursday evening, lofting two satellites into space. ArSat-1 and Intelsat DLA-1 (Intelsat 30) rode uphill on the Arianespace workhorse out of the European Spaceport in Kourou, French Guiana. Lift off came midway through a 51 minute launch window that opened at 21:44 GMT, following a weather and satellite related hold. (source: - more...)

16/10/2014 - NASA's MAVEN spacecraft has provided scientists their first look at a storm of energetic solar particles at Mars and produced unprecedented ultraviolet images of the tenuous oxygen, hydrogen and carbon coronas surrounding the Red Planet, said University of Colorado Boulder Professor Bruce Jakosky, the mission's principal investigator. In addition, the new observations allowed scientists to make a comprehensive map of highly variable ozone in the Martian atmosphere underlying the coronas, he said. ... (source: - more...)

15/10/2014 - Astronauts Reid Wiseman and Barry "Butch" Wilmore floated outside the International Space Station Wednesday and, after a bit of trouble with a balky bolt, replaced a broken voltage regulator in one of eight solar power channels to restore the lab's electrical grid to normal operation.

14/10/2014 - The US military's mysterious robot space plane is expected to land this week after a 22-month orbit, officials said Tuesday, but the craft's mission remains shrouded in secrecy. The unmanned X-37B, which looks like a miniature space shuttle, is due to glide back to Earth after having launched on December 11, 2012, on a mission that military officers say is strictly top secret. "Preparations for the third landing of the X-37B are underway at Vandenberg Air Force Base" in California, said a US Air ... (source: - more...)

14/10/2014 - Two US astronauts are set to step outside the International Space Station (ISS) to conduct the second of two recent spacewalks, aimed at replacing failed components and beginning the process of reconfiguring the station for the arrival of future commercial crew vehicles. The 6.5 hour EVA is scheduled to begin at 12:10 PM GMT on Wednesday. (source: - more...)

14/10/2014 - Russia will take the Moon exploration as a core of its space program for the next decade, Federal Space Agency Roscosmos said Friday. "This year Roscosmos has prepared a long-term program of deep space exploration, with exploration of the Moon as the core," the agency's official Yuri Makarov said. According to the Roscosmos official website, the new program is also aimed at exploring other planets in the Solar System. The program envisages building infrastructure of the permanent lunar ...

12/10/2014 - A $26 million science instrument carried to the International Space Station last month by SpaceX's Dragon cargo capsule has been switched on and is measuring winds over the world's oceans to help forecasters track the intensity of tropical cyclones, NASA officials said.

11/10/2014 - Mars One is a nonprofit that has plans to put humans on Mars by 2025, but doctoral students at MIT believe the current plans could put the colonists at risk of starving to death. The students used public information to simulate the mission and found that under the current plan, which calls for growing crops inside, it will be difficult to grow enough food for the colony while maintaining safe oxygen levels. "Our habitation simulations revealed that crop growth, if large enough to provide ... (source: - more...)

11/10/2014 - European satellite launch company Arianespace on Wednesday said a shortcoming in the design stages was behind an anomaly that occurred during August's Soyuz mission to carry two satellites in the Galileo constellation from Europe's Spaceport in French Guiana. "The root cause of the anomaly on flight VS09 is a shortcoming in the system thermal analysis during stage design, and not an operator error during stage assembly," an independent inquiry commission said. "The system thermal analyses ha ... (source: - more...)

08/10/2014 - Orbital’s Cygnus spacecraft will begin her latest trip to the International Space Station (ISS) on October 24, atop of the Antares carrier rocket – the rocket’s fifth launch in 18 months of operation. The ORB-3/CRS-3 mission will also debut the use of the more powerful Castor XL second stage motor, supplied by ATK. (source: - more...)

07/10/2014 - Japan put a new weather satellite into space Tuesday in the hope it can improve the forecasting of typhoons and detect volcanic gas plumes. The successful launch comes the day after a typhoon strafed Japan and just over a week after a volcano killed more than 60 people when it erupted without warning. The Japanese-made H-2A rocket carrying the Himawari-8 weather satellite blasted into a blue sky at the Tanegashima Space Center in southern Kagoshima prefecture at 2:16 pm (0516 GMT). The 17 bi ...
