Aurora Borealis can cause damage to satellites in severe solar storms. Scientists are experimenting to understand near-space weather better.
Some of the more well-known examples include retrievable and reusable rockets, retrieval at sea, mid-air retrieval, single-stage-to-orbit (SSTO) rockets, and kinetic launch systems.
In addition, there are also efforts to develop propulsion systems that do not rely on conventional propellants. This technology offers many advantages, including lower mass and improved energy efficiency, ultimately lowering costs.
On June 10, 2023, an all-electrical propulsion system for satellites (the IVO Quantum Drive) will fly to space for the first time. The system was built by North Dakota-based wireless power company IVO, Ltd. and will serve as a testbed for an alternative theory of inertia that could have applications for propulsion.
OneWeb’s latest satellite launch gives it enough coverage to offer global broadband from space, putting it in direct competition with SpaceX’s Starlink service.
The company will charge $50 million per launch of its next-gen rocket, bringing it in line with SpaceX.
Rocket Lab is developing a larger, reusable rocket called Neutron to help it compete with SpaceX’s Falcon 9 launch capabilities.
Rocket Lab’s Neutron will “compete directly with the Falcon 9”.

The SpaceX CEO explained that some satellites would likely have to be deorbited to burn up in Earth’s atmosphere.
(CNN) — Startup Relativity Space sent what it’s calling the “world’s first 3D-printed rocket” toward space on Wednesday, vaulting it into the upper reaches of the atmosphere. Though, it suffered an engine issue after launch and failed to reach orbit.
Terran 1, a 110-foot-tall (33.5-meter) vehicle designed to haul lightweight satellites into orbital space, lifted off from Cape Canaveral Space Force Station on Florida’s eastern coast at just before 11:30 pm ET. The rocket, powered by super-chilled methane and oxygen, burned a bright blue-green against the night sky.
After the first stage of the rocket — the bottommost portion of the rocket that gives the initial thrust at liftoff — expended its fuel, it detached from the rocket’s upper stage. But the engine meant to propel that portion appeared to ignite only briefly, leaving the rocket without enough power to reach orbit.
United Launch Alliance’s second-to-last Delta 4-Heavy rocket is scheduled to blast off from Cape Canaveral April 20 with a classified cargo for the U.S. government’s spy satellite agency, a mission that will mark ULA’s first flight of the year, officials announced this week.
ULA and the National Reconnaissance Office, the customer for the national security mission, announced the target launch date Tuesday.
The mission is known as NROL-68, and is expected to loft a large surveillance satellite into geosynchronous orbit, joining a fleet of government-owned spacecraft designed to eavesdrop on the communications of adversaries and foreign powers. But the NRO does not disclose details about its missions, and independent analysts use information about the rocket’s lift capability, trajectory, and similar past launches to predict the purpose of spy satellite missions.
It’s called the Einstein Probe and it’s meant to observe the changing universe.
China has ambitious plans to launch a new X-ray astronomical satellite called the Einstein Probe (EP) at the end of this year. This is according to a report by the ChinaDaily.
“The satellite has entered the final stage of development,” he said at the recent 35th National Symposium on Space Exploration.

This week the FCC voted 4–0 to approve a new effort to help satellite providers like SpaceX offer wireless cell phone service from space. SpaceX’s Starlink service already had a deal in place with T-Mobile to offer phone service in areas that currently does not have it.
“The Notice of Proposed Rulemaking adopted today proposes a framework through which satellite operators collaborating with terrestrial service providers would be able to obtain FCC authorization to operate space stations on certain currently licensed, flexible-use spectrum allocated to terrestrial services. The Commission is proposing to add a mobile-satellite service allocation on some terrestrial flexible-use bands.” The FCC said in a statement.
The FCC went on to say that this service could “serve a wireless provider’s customers should they need connectivity in remote areas, for example in the middle of the Chihuahuan Desert, Lake Michigan, the 100-Mile Wilderness, or the Uinta Mountains.”
There’s a mystery happening in some satellites facing the sun, and scientists from the National Institute of Standards and Technology (NIST) and the Laboratory for Atmospheric and Space Physics (LASP) are on the case. The team has been trying to figure out what is clouding up and compromising the performance of tiny, thin metal membranes that filter sunlight as it enters detectors that monitor the sun’s ultraviolet (UV) rays.
These detectors can warn us about impending solar storms—bursts of radiation from the surface of the sun—that could reach Earth and temporarily disrupt communications or interfere with GPS readings.
Last year, the team disproved the prevailing theory: that this clouding was a buildup of carbon on the surface of the filters from organic sources stowing away on the satellite.
