SpaceX’s highly anticipated launch of four “MicroGEO” communications satellites was called off at the final second on December 21. A Falcon 9 rocket, prepared for liftoff from Cape Canaveral Space Force Station in Florida at midnight EST (0500 GMT), faced an abrupt halt as its engines ignited. The reason for the mission’s suspension remains undisclosed, with the company yet to confirm a rescheduled launch date.

As per a report by Space.com, an initial statement by SpaceX indicated an attempt to relaunch on December 22, which was later reconsidered following detailed inspections of the rocket.The event marked an unexpected delay for a mission designed to deploy Astranis’ advanced satellites, highlighting the complexities inherent in space missions.

Mission Overview and Satellite Objectives

The satellites onboard were developed by Astranis, a San Francisco-based firm aiming to expand its satellite portfolio. Two satellites will serve Anuvu, a Colorado-based provider of in-flight connectivity for travellers. Another is destined for operations in the Philippines, while the fourth, named UtilitySat, will cater to diverse customers over its operational lifespan.

John Gedmark, Chief Executive Officer of Astranis, underscored the importance of this mission, in a statement, describing it as a pivotal step in expanding their satellite operations. He stated that the launch was to demonstrate the capability of deploying multiple satellites simultaneously, a milestone for the company.

Planned Deployment and Falcon 9 Reusability

Once launched, the Falcon 9’s upper stage was expected to place the satellites in geosynchronous transfer orbit approximately 35 minutes after liftoff. Meanwhile, the rocket’s first stage was scheduled to land on the droneship “A Shortfall of Gravitas,” marking its 17th flight. Astranis’ mission, titled “From One to Many,” reflects its ambition to expand geostationary broadband services. The next launch schedule is pending confirmation, as per the report.

NASA’s X-59 Moves Closer to First Flight with Advanced Taxi Tests and Augmented Vision

X-59 of NASA has been designed from the ground to fly at a faster speed of sound without making thunderous sonic booms, which are usually associated with supersonic flight. This 99-foot aircraft, which features a logically elongated design, jettisons the front windscreen and is now heading towards the runway. Pilots can see what is at the front through an augmented reality (AR) enabled closed-circuit camera system, which is termed by NASA as the External Vision System (XVS). NASA took control of an experimental aircraft and performed taxi tests on it during this month.

X-59’s Futuristic Design: Eliminating Sonic Booms with External Vision System

According to As per NASA, the test pilot Nils Larson, during the test, drove the X-59 at the runway by keeping a low speed. This is done to ensure the working of the steering and braking systems of the jet. Lockheed Martina and NASA would perform the taxi tests at high speed, in which the X-59 will move faster to make it to the speed at which it will go for takeoff.

Taxi tests are held at the U.S. Air Force’s Plant 42 facility in Palmdale, California. The contractors and the Air Force utilise the plant for manufacturing and testing the aircraft. Lockheed Martin has developed this aircraft, whose Skunk Works is found in Plant 42.

Taxi Tests at Plant 42: NASA and Lockheed Martin Prepare X-59 for First Flight

Some advanced aircraft of the U.S. military were developed to a certain extent at Plant 42, together with the B-2 Spirit, the F-22 Raptor, and the uncrewed RQ-170 Sentinel spy drone.

SOFIA airborne observatory aircraft, which is a flying telescope called Plant 42, home recently retired. The space shuttle of the agency is the world’s first reusable spacecraft; these were assembled and tested at the facility.

Such taxi tests have started over the last months. NASA worked in collaboration with the Japan Aerospace Exploration Agency for testing a scale model of the X-59 in the supersonic wind tunnel to measure the noise created under the aircraft.

Unusual Plasma Waves Above Jupiter’s North Pole Can Possibly Be Explained

In recent observations, NASA’s Juno spacecraft has significantly detected the presence of a variety of plasma waves. The emergence of these waves on Jupiter’s powerful magnetic field is projected to be surprising, as their existence was never marked in the planetary magnetospheres. However, scientists might have come out with an explanation. Furthermore, the current studies have been questioned by scientists surfacing the activity at the North Pole. The article below will exemplify the findings and shed light on the plasmas. 

Uncovering Mystery at Jupiter’s North Pole 

According to a paper published in the Physical Review Letters, the scientists have uncovered the explanation behind the presence of these strange waves. They mainly suspect that the formation of these waves lies behind their evolution as a plasma, which later transforms into something different. 

Inside Jupiter’s Plasmas and Their Variants 

Plasmas are best referred to as the waves that pass through the amalgamation of the charged particles in the planet’s magnetosphere.These plasma waves come across in two forms: One, Langmuir waves, which are high-pitched lights crafted with electrons, while the other, Alfven waves, are slower, formed by ions (heavy particles). 

About Juno’s Findings

As unveiled by the Juno, the findings turned out to be questionable after the scientists noted that in Jupiter’s far northern region, the plasma waves were relatively slower. The magnetic field is about 40 times stronger than the Earth’s, but scientists were shocked to witness the results as the waves were slower. To analyse this further, a team from the University of Minnesota, led by Robert Lysak, identified the possibility of Alfven waves transforming into Langmuir waves. Post studying the data extracted from the Juno, the researchers then began to compare the relationship between the plasma wave frequency and number. 

According to Lysak’s research team, near Jupiter’s north pole, there might be a potential pathway of Alfven waves, which are massive in numbers, transforming into Langmuir waves. Scientists are also predicting that the reason behind evolution might be strong electrons that are shooting upwards at a very high energy. This discovery was made in the year 2016. Considering the current findings, the researchers indicate that Jupiter’s magnetosphere may comprise a new type of plasma wave mode that occurs during high magnetic field strength.

Russia Expands Space Weather Network, Launches Iran’s Nahid-2 in Joint Mission

Russia sent two new Ionosfera-M satellites into orbit on a Soyuz-2 on July 25, 2025. Rocket 1b from the Vostochny Cosmodrome in Siberia. The mission also placed Iran’s Nahid-2 communications satellite in orbit. These satellites will complement a four-satellite constellation aimed at keeping track of Earth’s upper atmosphere and space weather conditions, particularly the solar wind that can knock satellites and communications systems offline. The flight indicates Russia’s scientific ambitions and collaboration with Iran’s space program, showing Russia’s function in launching Tehran’s orbital assets. Both countries gain from the collaborative mission.

Russian Space Weather Satellites

According to official sources, Russia’s new Ionosfera-M probes, 3 and 4, follow two identical satellites launched in November 2024. Together the four craft form a mini-constellation orbiting about 820 kilometers above Earth. The network is explicitly designed to study space weather in the ionosphere, the charged upper atmosphere.

It will track solar wind and related phenomena that can disturb communications and navigation systems. The latest pair is being inserted into an orbital plane perpendicular to the first two, greatly expanding three-dimensional coverage of near-Earth space. They also carry a new Ozonometr-TM instrument to measure upper-atmosphere ozone for the first time in this mission.

Iranian Payload and International Implications

An Iranian communications satellite, Nahid-2, was also aboard the Soyuz mission.Nahid-2 is intended to bolster Iran’s civilian communications in space, an important capability given Iran’s limited homegrown launch capabilities. Russia’s role in the delivery of the payload reflects cooperation between the countries in space technology.

With the help of Russia, Iran can continue its satellite building efforts, even though these are restricted by the international community from also involving rocket export limitations. That Moscow has such a product even while Iran is under sanctions underscores the depth of their two-nation space partnership. This mission represents Russia’s support for ally’s space aspirations and the broader geopolitical implications of such collaborative efforts.
