SpaceX lands 100th Falcon booster

Posted by in categories: materials, satellites

Exactly six years after its first successful recovery, SpaceX has landed a Falcon booster for the 100th time.

On December 21st, 2015, the first Falcon 9 V1.2 Full Thrust (Block 1) rocket lifted off from SpaceX’s Cape Canaveral LC-40 launch pad on the company’s return-to-flight mission after a catastrophic in-flight failure just six months prior. Unwilling as ever to waste an opportunity, no matter how important the mission, SpaceX – on top of debuting a major Falcon 9 upgrade – chose to take advantage of the return to flight to attempt to land a Falcon booster back on land for the first time ever. Ultimately, on top of successfully deploying multiple Orbcomm OG2 communications satellites in orbit for a paying customer, Falcon 9 booster B1019 sailed through its boostback, reentry, and landing burns without issue. About nine minutes after liftoff, the rocket ultimately touched down on a concrete “landing zone” just a few miles from where it lifted off with uncanny ease relative to SpaceX’s numerous failed attempts in the ~18 months prior.

Exactly six years later, on December 21st, 2021, Falcon 9 booster B1069 lifted off from Kennedy Space Center (KSC) Pad 39A with an upgraded, flight-proven Cargo Dragon in tow for SpaceX’s 24th International Space Station (ISS) resupply mission. CRS-24 also marked the company’s 31st and final launch of 2021, representing more successful Falcon launches completed in a single year than SpaceX had even attempted in its entire nine-year history up to the point of that first successful booster landing.

A global model for tackling space sustainability and safety

Posted by in categories: business, geopolitics, military, satellites, sustainability, treaties

For more than 50 years, near space has been viewed as a vast resource to exploit with few limits. In reality, near space is a very scarce resource. While international agreements such as the Outer Space Treaty and the Registration Convention take steps to protect this precious resource, no single global body is responsible for ensuring the long-term sustainability and safety of near space.

The current surge in the exploitation of outer space means that this lack of a global framework for space sustainability must be addressed immediately, or it will be too late; near space will be cluttered and unrecoverable. We are seeing increased use of near space for tourism and other business ventures and the deployment of megaconstellations comprising tens to hundreds of thousands of satellites. And this is just the start. Last month, we witnessed a Russian anti-satellite test that left portions of near space cluttered with orbital debris. Failure to implement a global framework with an enforcement mechanism for space sustainability could severely impact the ability to fully utilize the resource in the near future.

Today near space activities are subject to disparate space sustainability requirements, generally reliant on the requirements of the object’s launching state or conditions imposed by countries in which entities have market access. Some countries have developed well-crafted requirements for at least some space objects, but others have not. In addition, except for the items covered in existing treaties, like launching state liability, there is almost no harmonization on requirements, which further jeopardizes space sustainability.

Malaysia outlines national space blueprint with focus on remote-sensing satellite development

Posted by in categories: economics, policy, satellites, security, space

SEOUL, South Korea — Malaysia is developing a national space blueprint to drive the growth of its space sector, particularly the manufacturing of remote-sensing satellites, satellite components and data-driven downstream services.

During a Dec. 13 parliamentary hearing, a deputy minister shared the latest update on the “Malaysia Space Exploration 2030” blueprint being fleshed out by Malaysia’s Ministry of Science, Technology and Innovation.

The deputy minister overseeing the effort, Datuk Ahmad Amzad Hashim, said the blueprint outlines a 10-year strategy in line with Malaysia’s National Space Policy 2030. The policy, adopted in 2017, recognizes the importance of space technologies for the country’s economic growth and national security.

Orbital Insight to build AI for intelligence community based on artificial data

Posted by in categories: business, information science, robotics/AI, satellites

WASHINGTON – The National Geospatial-Intelligence Agency has selected a team of commercial and academic partners to build an artificial intelligence system with synthetic data, which will further help the agency determine how it builds machine learning algorithms moving forward.

Orbital Insight was issued a Phase II Small Business Innovation Research contract by the NGA, the company announced. Dec. 16. It will collaborate with Rendered.ai and the University of California, Berkeley, to develop a computer vision model.

As the organization charged with analyzing satellite imagery for the intelligence community, NGA has put increased emphasis on using AI for its mission. The agency sees human-machine pairing as critical for its success, with machine learning algorithms taking over the rote task of processing the torrent of satellite data to find potential intelligence and freeing up human operators to do more high level analysis and tasks.

Stanford’s gecko-inspired robot hand sets its sights on fruit picking

Posted by in categories: robotics/AI, satellites

Stanford’s made a lot of progress over the years with its gecko-inspired robotic hand. In May, a version of the “gecko gripper” even found its way onto the International Space Station to test its ability to perform tasks like collecting debris and fixing satellites.

In a paper published today in Science Robotics, researchers at the university are demonstrating a far more terrestrial application for the tech: picking delicate objects. It’s something that’s long been a challenge for rigid robot hands, leading to a wide range of different solutions, including soft robotic grippers.

Watch NASA’s IXPE Observatory Launch Into Space — Official Live Broadcast

Posted by in categories: cosmology, satellites

We’re sending a new pair of X-ray eyes into the universe!

NASA’s Imaging X-ray Polarimetry Explorer (IXPE) is our first satellite dedicated to measuring the polarization of X-rays. Polarized light is made up of electric fields that vibrate in a single direction—and IXPE’s state-of-the-art X-ray vision will help scientists study the spin of black holes, the magnetic fields of pulsars, and other cosmic phenomena.

Visualizing the propagation path of electromagnetic waves from space to ground

Posted by in categories: particle physics, satellites

Using data on electromagnetic (EM) waves and plasma particles measured simultaneously via multiple satellites, an international collaborative research group has discovered the existence of invisible “propagation path” of EM waves and elucidated the mechanism by which EM waves propagate to the ground.

It is known that various kinds of EM occur naturally in geospace and cause variations in the plasma environment that surrounds the Earth via a known as wave–particle interaction. In particular, when geospace storms occur due to disturbances of sun and solar wind, EM waves become more active, and variations of geospace environment sometimes, may cause damage to spacecrafts, expose astronauts to radiation, and cause terrestrial power grid failures. To understand variation in the plasma environment caused by EM waves in , in-situ measurement has been performed in space using spacecrafts, such as the Japanese geospace satellite Arase.

As EM waves in space propagate far away from their origin, to correctly understand the effects of EM waves, it is crucial to understand where in space the EM waves are generated and how they are propagated. However, it has been difficult to unravel the origin of EM waves and the mysteries of how EM waves spread spatially using only single-point observation. “Electromagnetic ion cyclotron waves (EMIC waves),” which are the focus of this study, are an important class of EM wave in geospace that control variations in the geospace plasma environment. The source region of ion mode waves has a finite spatial extent, and generated EMIC waves are considered to propagate north to south along the geomagnetic field lines. The specific spatial size of the EMIC wave source region and the 3D aspect of how the propagation path is formed from space to ground are yet to be elucidated.
