There are currently thousands of Starlink satellites that belong to SpaceX, and they are causing a lot of disputes in the science and astronomy communities. They are disrupting scientific research by causing streaks in deep space photos, and according to a new study are also dumping “unintended electromagnetic radiation” into space, which could be a major problem for Earth-bound astronauts.

The study published in Astronomy & Astrophysics states that the satellites in low Earth orbit could be muddling or even drowning out signals from deep space that radio astronomers search for.

SpaceX’s veteran Falcon 9 booster, B1058, made its 16th launch on Sunday. This was the 216th successful mission for the series and a record-breaking event for the company.

On the night of July 9, 2023, SpaceX made space history with yet another successful Falcon 9 rocket launch. Blasting off from the Space Force Station in Cape Canaveral, Florida, the rocket carried a payload of Starlink satellites before landing its first stage booster on a drone ship in the Atlantic Ocean.

This is pretty much par for the course for SpaceX, but what is more incredible is that this was the 16th launch and landing of its B1058 Falcon 9 rocket booster. The company now hopes to be able to use the same booster… More.

China’s LandSpace is getting ready to launch its revolutionary ZQ-2 methane-powered rocket for the second time sometime this year.

Chinese space tech company LandSpace is gearing up to launch its revolutionary methane-propelled rocket, the Zhuque-2 (ZQ 2), for the second time sometime this year. Scheduled to blast off from the company’s launch facility in the Gobi Desert, the mission will deliver a satellite into space. LandSpace, widely considered China’s answer to SpaceX, the launch is hoped to cement further the utility of using methane as a reliable next generation of rocket fuel.

The company’s rockets are ferrying astronauts, launching satellites and dominating any competition.

The joint research team of Electrical Engineering and Computer Science Professor JeongHo Kwak at the DGIST and Aerospace Engineering Professor Jihwan Choi at the KAIST have proposed a novel network slicing planning and handover technique applicable to next-generation low-Earth orbit (LEO) satellite network systems. Findings of the study have been published in the journal IEEE Vehicular Technology Magazine.

LEO satellite networks refer to communications networks with satellites launched within 300–1,500km, established for a stable supply of Internet services. Unlike base stations on land in which radio signals are often interfered with by mountains or buildings, LEO satellites can be launched to build communications networks to places with low population density where base stations could not be set up, thereby allowing them to receive the spotlight as a next-generation satellite communications system.

Accordingly, as more and more satellites are placed in lower orbits, satellite networks are expected to be formed as an alternative to terrestrial networks using links between LEO satellites. However, LEO satellites move in predictable orbits, and their connection within the network is wireless, which is why LEO satellite networks must be considered from a different view than terrestrial networks.

UK company ODIN Space has demonstrated a space junk sensor, which could map and analyse debris with sub-centimetre precision.

SpaceX recently launched a Falcon 9 rocket delivering the Transporter 8 mission, a rideshare carrying various microsatellites and nanosatellites into orbit for commercial and government customers. These payloads included new sensor technology by ODIN Space, installed on a D-Orbit ION satellite. ODIN Space has now confirmed that the spacecraft has successfully begun to capture data from its surroundings.

A new navigation system that tracks subatomic particles constantly bombarding Earth could help us get around indoors, underground, and underwater — all the places GPS fails.

The challenge: GPS (the Global Positioning System) is a group of 31 satellites, constantly transmitting radio signals from about 12,500 miles above Earth’s surface. Receivers in phones, cars, planes, and ships then use data from multiple satellites’ signals to calculate their own locations on Earth.

While GPS has revolutionized surface transportation, satellite signals can reflect off solid surfaces, making the navigation system incapable of accurately pinpointing the locations of receivers indoors, underground, and underwater.

This advancement is made possible through lasers acting as data carriers, offering a much wider spectrum than traditional microwave technology. The deployment of this cutting-edge technology is expected to revolutionize ground communication with satellites.

SpaceX has announced a plan to give T-Mobile customers direct access to the Starlink satellite constellation, ensuring they’ll have mobile coverage nearly everywhere in the US.

“I think this is really a massive game changer,” said SpaceX CEO Elon Musk during a live event at SpaceX’s Starbase facility in Texas. “In a nutshell, it’s no more dead zones.”

The challenge: Cell coverage is widespread in the US, but there are still more than half a million square miles — nearly twice the size of Texas — where you won’t find a signal from any carrier.
