Only 1 300 out of about 6 000 satellites launched since the beginning of the space age are operational

Posted by in category: satellites

The D3 project, funded by the EU, is developing a decommissioning device, to be installed on the satellite prior to launch, that removes old satellites when they reach the end of their missions or their lives or when a major failure occurs.

China is once again being put to the spotlight after it has revealed that they are preparing to launch their anti-satellite missile that is believed to have the ability of destroying satellites in space. Authorities of the said project says that this is definitely one of Beijing’s most potent asymmetric warfare weapons. one of Beijing’s most potent asymmetric warfare weapons. It was found that the US intelligence officials have already detected preparations for a test launch of the Dong Neng-3 which is due to take place at a military facility in central China. However, despite these information, riva; countries said that little is known about the missile and the satellite.

SpaceX Wants to Surround Earth With an Internet Service That’s 200 Times Faster

Posted by in categories: Elon Musk, internet, satellites

SpaceX, the aerospace company founded by the Mars-hungry tech entrepreneur Elon Musk, just made a big move to enshroud the planet in high-speed internet coverage.

On November 15, the company filed a lengthy application with the Federal Communications Commission (FCC) to launch 4,425 satellites. (We first heard about the filing through the r/SpaceX community on Reddit.) That is a hell of a lot of satellites.

According to a database compiled by the Union of Concerned Scientists, there are 1,419 active satellites currently orbiting Earth.

DARPA developing robots to fix and maintain satellites that are one tenth of the distance to the moon

Posted by in categories: robotics/AI, satellites

DARPA is developing robotic support and maintenance of geosynchronous Earth orbit satellites with the Phoenix and GEO programs

The traditional process of designing, developing, building and deploying space systems is long, expensive and complex. These difficulties apply especially to the increasing number of expensive, mission-critical satellites launched every year into geosynchronous Earth orbit (GEO), approximately 22,000 miles above the Earth. Unlike objects in low Earth orbit (LEO), such as the Hubble Space Telescope, satellites in GEO are essentially unreachable with current technology.

Minimum Interstellar Precursor Mission

Posted by in categories: energy, satellites

With the continuous advancements in nano-satellite technology, there has been a significant increase in proposed CubeSat missions for sophisticated space exploration. Due to their cost efficiency, rapid development and ongoing miniaturization of satellite bus systems and scientific payloads, CubeSats offer the potential to increase the range of capabilities of deep space explorations. Missions already on launch manifests such as Mars Cube One, Lunar Flashlight, and NEA Scout will demonstrate the use of CubeSat technology for planetary explorations. CubeSat capabilities are also being expanded for other deep space missions and for the detection technique of Near Earth Objects (NEOs). With the increase in anticipated that CubeSats will increasingly become an attractive option to conduct cost-effective interplanetary missions. This increase in interest and development allows further advancement of Technology Readiness Level (TRL) of the present technology, which can be extrapolated for extra-solar and near interstellar missions. The work presented in this paper addresses the potential utilization for interplanetary and near interstellar missions using technology developed from off-the-shelf components. The paper introduces the current CubeSat technologies, their baselines TRLs, and the requirements needed to conduct such missions. It further presents the feasibility study of the available CubeSat technology to conduct near interstellar mission by the year 2030. The feasibility of different propulsion, communication, electrical and power subsystems with a TRL level of 5 and higher in the next 10 years is evaluated. This paper outlines the fundamental mission and spacecraft architecture required to exit the solar system using miniaturized space system technologies. The analysis and suggestions presented in this paper help recognize the resourcefulness of CubeSat for interplanetary and the edge of the solar system missions.

Elon Musk’s SpaceX wants to launch thousands of satellites into space with the aim of providing super-fast global internet coverage, according to a regulatory filing.

SpaceX – the company on a mission to colonize Mars – outlined plans to put 4,425 satellites into space in a Federal Communications Commission (FCC) filing from earlier this week.

Australia developing low cost hypersonic second stage for small satellite launches

Posted by in category: satellites

Once you get to mach 5+ hypersonic speed, then a scramjet works and it is by far the most efficient type of engine for hypersonic speeds. A scramjet needs some other form of propulsion to get it to Mach 5. As a result, scramjets have become something of a well-studied technology in search of a practical application.

To reach these hypersonic speeds, Michael Smart, professor of hypersonics at the University of Queensland in Brisbane plans to combine an uncrewed scramjet with conventional rockets. He believes his Spartan launch system could radically reduce the costs of blasting satellites into orbit.

“All conventional satellite launch systems use different stages,” says Smart. “There’ll be a first stage rocket that normally gets up to Mach 5 or 6, you’ll have a second scramjet stage that goes two thirds of the way to space and you’ll have a final upper stage that takes the satellite into orbit.”

SpaceX filed with FCC to operate 4400 satellites and Elon Musk SpaceX shares are worth $8.1 billion

Posted by in categories: Elon Musk, internet, satellites

Today, SpaceX filed with the FCC to obtain the rights to operate 4,400 satellites to offer internet services from orbit, a plan that was announced last year.

Elon Musk’s trust currently owns 54% of the outstanding stock of SpaceX and has voting control of 78% of the outstanding stock of SpaceX.
