Recent advancements in space exploration include groundbreaking exoplanet imaging, progress in private space missions, and the expansion of satellite constellations. These developments are pushing the boundaries of our understanding of the universe and enhancing our capabilities in Earth observation and space-based research.

Webb Telescope’s new Discoveries in Exoplanet Imaging

The James Webb Space Telescope (JWST) continues to revolutionize our understanding of exoplanets with its advanced infrared capabilities. Recent studies have focused on imaging colder, older exoplanets, a feat previously unattainable. This new capability allows scientists to study a wider range of exoplanets, providing insights into their composition, structure, and potential habitability.

“The colder an exoplanet,the harder it is indeed to image,so this is a totally new regime of study that Webb has unlocked with its extreme sensitivity in the infrared,” said William Balmer,a Ph.D.student at Johns Hopkins University and first co-author of the published study. “We are now able to add to the catalog of not just hot, young exoplanets imaged, but older exoplanets that are far colder than we’ve directly seen before Webb.”

The new study uncovers fascinating details about the system’s structure. Unlike most known solar systems, where planets orbit in the same plane, the two planets here follow orbital paths tilted 40 degrees apart-forming an unusual X-shaped configuration. Researchers are now trying to understand what caused this unusual alignment, speculating that a third planet may once have existed and was violently ejected, altering the orbits of the remaining planets.

“we are now able to add to the catalog of not just hot, young exoplanets imaged, but older exoplanets that are far colder than we’ve directly seen before Webb.”

Private Mission to the ISS Faces Delays

Axiom Space’s fourth private mission to the International Space Station (ISS), AX-4, has experienced multiple postponements. Originally scheduled for launch last week, the mission faced delays due to a liquid oxygen (LOx) leak from the first stage of the Falcon 9 rocket. Axiom and SpaceX have announced an indefinite postponement as they address the technical issues.

Commanding the mission is veteran astronaut Peggy Whitson, who holds the U.S. record for the most cumulative time in space-675 days.She is joined by three astronauts sponsored by their respective home countries: Shubhanshu Shukla from India, Sławosz Uznański-Wiśniewski from Poland (representing the European Space Agency) and Tibor Kapu from Hungary.

among the mission’s scientific objectives is an Israeli-led experiment investigating upper-atmospheric phenomena that occur during thunderstorms-transient events that flash above the clouds and last onyl fractions of a second. The experiment is led by Prof. Yoav Yair of Reichman university, who provides the astronauts with exact instructions for capturing these split-second events by coordinating lightning storm data with the ISS’s position. Hungarian astronaut Tibor Kapu is expected to carry out the imaging, but the entire AX-4 crew was trained for the experiment by Yair and Israeli astronaut Eytan Stibbe, in the hope that others will also contribute during their free time.

The experiment, in its current form, has been ongoing since AX-1, nearly three years ago, when it was first carried out by Israeli private astronaut Eytan Stibbe during the Rakia Mission.The Rakia Mission later became a public benefit company, and has continued to support the experiment’s inclusion in subsequent Axiom missions. While AX-2 yielded disappointing results, AX-3 produced promising data. For AX-4, the experiment will be conducted in collaboration with Prof. József Bór of the Hungarian Institute of Earth and Space Sciences.

The Rakia Mission is also contributing to the Indian component of AX-4, assisting in the progress of educational content and helping to establish a visitor center and mission control room at the massive CMS school in Lucknow, India-where astronaut shukla studied.

Rocket Lab Expands Satellite Constellation for iQPS

Rocket Lab has successfully launched another radar satellite for the Japanese company iQPS. The satellite was launched aboard Rocket lab’s Electron rocket from its launch site in New Zealand and entered its planned orbit-at an altitude of 575 kilometers-shortly after liftoff. This is the fourth satellite Rocket Lab has launched for the Japanese company and the third launch this year in this series,part of a deal to launch eight satellites over the course of this year and next.

iQPS is developing a satellite constellation to provide radar imaging services to its clients. The goal is to establish a 36-satellite network offering global coverage, which would enable real-time tracking of surface changes-ranging from the movement of ships at sea to herds of animals on land.

Rocket lab is steadily establishing itself as a leading player in launching small- to medium-sized satellites using its Electron rocket.Last week’s launch marked the 66th flight of the Electron and the eighth so far this year. The company has secured several contracts with firms deploying satellite constellations for military and civilian data purposes, including BlackSky, Synspective and OroraTech and it aims to reach 20 prosperous launches in 2025.
