SpinLaunch kinetic launch system celebrates a successful test flight

SpinLaunch kinetic launch system celebrates a successful test flight

The thing that has been common for every satellite put into orbit in the history of spaceflight is that they've all used rockets. However, the need for rockets is changing with a company called SpinLaunch celebrating the first successful test launch for its kinetic launch system. The launch system doesn't use a rocket and is zero emissions.

NASA shares the first images from Landsat 9

NASA shares the first images from Landsat 9

In late September of this year, NASA and the US Geological Survey launched the latest satellite in the Landsat fleet called Landsat 9. The satellite has now collected and shared its first images of Earth. The images were taken on October 31 and show how the mission will help manage resources and understand how climate change is impacting the planet. The Landsat series of satellites have been in operation for nearly five decades.

Landsat 9 will launch on Monday

NASA plans to launch a new and advanced satellite for studying the Earth on Monday. The satellite is called Landsat 9, and as its name suggests it is the ninth satellite in the line to head into orbit. Landsat satellites have been in orbit and imaging the Earth for the last five decades. The satellite has seval high-tech instruments aboard.

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.
