SpaceX launch on Sunday will put a Sirius-XM satellite into orbit

SpaceX launch on Sunday will put a Sirius-XM satellite into orbit

In the last few years, anyone who purchased a vehicle probably got a free subscription to Sirius-XM satellite radio with it. Satellite radio is very convenient for people who drive all the time or don't have any radio stations in their area that play the type of music they like. The best thing about satellite radio is that you can drive coast-to-coast listening to the same station.

Warming in the lower atmosphere may be more significant than expected

Warming in the lower atmosphere may be more significant than expected

Research conducted at the Lawrence Livermore National Laboratory (LLNL) has found something that may surprise many people. According to climate scientists and contributors on the project, satellite measurements of the troposphere temperature may have underestimated global warming over the last four decades. The troposphere is the lowest region of the atmosphere.

Starlink Internet service could be “fully mobile” by the end of the year

SpaceX CEO Elon Musk and his company are working hard to put more satellites into orbit capable of providing Internet access to people worldwide. So far, SpaceX has hundreds of Starlink satellites in orbit, with more set to launch during the year. Recently Musk made an exciting announcement that the Starlink Internet service could be fully mobile by the end of 2021.

Decommissioned NOAA-17 satellite breaks up in orbit

Decommissioned NOAA-17 satellite breaks up in orbit

One of the biggest concerns about space junk and decommissioned satellites orbiting the earth is a collision. It appears that satellites are moving very slowly when we see them on video taken from spacecraft or the ISS shared by NASA. However, satellites are orbiting at extremely high velocities, and even the smallest amount of debris can cause catastrophic consequences to other satellites, the ISS, and its crew members. Recently, the NOAA-17 satellite that was decommissioned in 2013 broke up in orbit.

Japan is holding microsatellites built with Myanmar aboard the ISS

Japan is holding microsatellites built with Myanmar aboard the ISS

JAXA is holding a pair of microsatellites built in cooperation with Japan's Hokkaido University in a joint project with the government-funded Myanmar Aerospace Engineering University (MAEU) aboard the ISS. The satellites being held aboard the space station are a pair of 50-kilogram microsatellites fitted with cameras intended to monitor agriculture and fisheries. The satellites are being held aboard the ISS while JAXA and the University are trying to decide what to do with them. Some Japanese officials fear the satellites could be used for military purposes after a coup by the junta seized power on February 1.

SpaceX wants to put Starlink satellite dishes on large vehicles

SpaceX wants to put Starlink satellite dishes on large vehicles

SpaceX's somewhat controversial Starlink satellite constellation aims to bring high-speed Internet to places that traditional cables and radio waves don't always reach. It seems that it doesn't just apply to remote areas but also to moving vehicles that don't always get the best Internet connectivity. In line with that grand goal, SpaceX is asking the FCC for permission to deploy Starlink even on trucks, aircraft, and trucks.

Space hurricane discovered in observation data from 2014

Space hurricane discovered in observation data from 2014

Scientists have recently confirmed the first observations of a space hurricane in the earth's upper atmosphere. The observations were made by satellites in August 2014 but were only recently discovered by a team of scientists from the University of reading and Shandong University in China. The observations confirm the existence of space hurricanes and shine a light on the relationship between planets and space.

Odd stripes spotted by NASA satellite in Russia baffle scientist

Odd stripes spotted by NASA satellite in Russia baffle scientist

A NASA satellite orbiting the earth taking pictures has spotted something that has scientists stumped in Siberia's cold Arctic reaches in Russia. Near the Markha River in Siberia, the earth has ripples that scientists don't completely understand. NASA recently posted new images of the odd landscape to its Earth Observatory website, taken with the Landsat 8 satellite over several years.

Lockheed Martin makes changes to GPS satellites so they can be upgraded in orbit

Lockheed Martin makes changes to GPS satellites so they can be upgraded in orbit

Typically when a satellite needs to be upgraded, it's simply replaced with a new satellite. Lockheed Martin is looking to change that and is redesigning the bus used for GPS satellites so they can be or upgraded with new hardware while in orbit. Word of the satellite changes came from a Lockheed Martin executive earlier this week.

Brazil’s first self-developed satellite will keep an eye on the rain forests

Brazil’s first self-developed satellite will keep an eye on the rain forests

Much of Brazil is packed full of dense rain forests that are critical to our planet's environment. Many feel like the clearing of the Amazonian rain forests are a detriment to the entire world, and efforts are being made to protect them. Brazil is set to launch its first homemade satellite known as Amazonia-1, and the entire satellite was developed within the country.
