Successful flight test of fuel cell in PSLV-C58 by ISRO..

Fuel cell payload

The Indian Space Research Organisation (ISRO) has achieved a significant milestone with the successful flight test of a 100 W class Polymer Electrolyte Membrane Fuel Cell based Power System (FCPS) onboard its orbital platform, POEM3. Launched as part of PSLV-C58 on January 1, 2024, this breakthrough experiment marks a pivotal step in assessing the operation of Polymer Electrolyte Membrane Fuel cells in space and gathering crucial data for the design of systems for future space missions.

During the short-duration test aboard POEM, the FCPS generated 180 W power by harnessing Hydrogen and Oxygen gases stored onboard in high-pressure vessels. The success of this experiment provides a wealth of data on the performance of various static and dynamic systems integral to the power system, shedding light on the intricate physics involved.

Hydrogen Fuel Cells, employed in this innovative system, directly produce electricity from Hydrogen and Oxygen gases, yielding pure water and heat as byproducts. Operating on electrochemical principles rather than combustion reactions, these fuel cells prove highly efficient. Notably, their emission-free nature, with water as the sole byproduct, positions them as ideal candidates for space missions involving human presence. The ability to simultaneously generate electric power, water, and heat makes them versatile for meeting multiple mission requirements.

Beyond space exploration, Fuel Cells hold substantial potential for societal applications, offering a clean energy solution for various types of vehicles and standby power systems. Their efficiency, comparable range, and rapid fuel recharge time distinguish them from conventional engines, presenting a promising avenue for emission-free transportation.

Fuel Cells emerge as an ideal power source for space stations, providing not only power but also pure water—a critical resource in space environments. ISRO's successful flight test of the Fuel Cell in PSLV-C58 marks a leap forward in advancing clean and efficient energy solutions for both space exploration and terrestrial applications, ushering in a new era of sustainable technology.

In the triple-star system, KOI-5Ab is seen orbiting the primary star...

KOI-5Ab continues to be a topic of discussion for researchers, as koi-5Ab has been seen orbiting the primary Star, confirming it has also been announced. koi-5ab revolves around the primary star, it was thought to be a planet half the size of Saturn in a planetary system, and was the only other planet candidate to be detected by the KOI-5Ab mission. Kepler mission operations were initiated by NASA in 2009, by the end of spacecraft operations in 2018, the Kepler spacecraft had discovered 2,394 exoplanets, or planets orbiting stars beyond our sun, and about 2,366 exoplanets such There are also those, which are still to be confirmed. David Ciardi, chief scientist at NASA's Exoplanet Science Institute, says the KOI-5AB was abandoned, because it was complicated, and we had thousands of candidates, and we were learning something new every day from Kepler, so that the KOI Mostly forgot to -5. KOI-5Ab is part of the Triple Star system, where KOI-5 is a group of three st...

NASA's Spitzer Space Telescope will be closed.

NASA briefly informed that the Spitzer Space Telescope will be permanently discontinued on January 30, 2020. After about 16 years of discovering the universe in light energy. And by that time, the space shuttle has been working for more than 11 years beyond its prime mission, Spitzer examines the universe's various objects in infrared light. It was in 2003 through the rocket that the American Space Research Organization NASA entered the space and entered the orbit around the Earth. Spitzer rotates the sun on a path similar to that of the Earth but it runs a bit slower. Today it is about 158 million miles (254 million kilometers) away from our planet - more than 600 times the distance between Earth and Moon. The spacing of Spitzer's orbit curve means that when the spacecraft indicates its fixed antenna on the earth to download data or receive commands, its solar panels tend to lean away from the sun. During those periods, to operate the space shut...

SpaceX is launching its next dragon spacecraft.

SpaceX is preparing for its next mission, very soon Spacex will launch the Dragon Spacecraft with its Falcon 9 Rocket. SpaceX is the 18th commercial reproduction service mission, dragon spacecraft will be loaded with dozens of experiments made in space. Launch date: Sunday, July 21, 2019 at 7:35 pm International Space Station (ISS) us The National Laboratory SpaceX's dragon is giving a finalization to more than two dozen payloads for launch in a circular circular laboratory. Many of these payloads are aimed at improving human health on the earth, many of which are focused on drug development. In addition, a series of payloads from identified private sector partners will be launched on this mission. More than 40 student experiments and demonstrations have been included on the 18th Commercial Recepti Services Mission (CRS-18) of SpaceX. One part of ISS American National Laboratory's goal is to encourage and engage next generation scientists. ...

NASA's review of the flight design of the Nancy Grace Roman Space Telescope successfully confirmed.

Critical design work for the NASA Nancy Grace Roman Space Telescope has been completed, and the design analysis has also been successfully completed, indicating that all design and developmental engineering work is now complete. The Nancy Grace Roman Space Telescope is being managed at NASA's Goddard Space Flight Center in Greenbelt, Maryland, along with NASA's Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science stream consisting of various scientists team is involved. After an analysis of extensive hardware testing and sophisticated modeling, an independent review panel confirms that the observatory we used, said Julie McEnery, senior project scientist for the Roman Space Telescope at NASA's Goddard Space Flight Center in Greenbelt, Maryland. Ready, it will work. Julie McNairy says of the Roman Space Telescope, what we know, what it will look like, and what it is capable of doing, and now th...

SpaceX,Dragon Cargo Returns Mission in Pacific ends with SplashDown

SpaceX dragon cargo spaceship dropped at 5:48 pm in the Pacific Ocean. The EDT (2:48 p.m. PDT) is located approximately 202 miles southwest of Long Beach, California, which is located at the end of the company's 17th contracted Cargo Resipulli mission for NASA. Spacecraft returned more than 4,200 pounds for other valuable scientific uses. Some scientific investigations of Dragon's return to Earth include: Overview of protein crystals growth, in the ...

A cluster of three galaxies was imaged with the help of the Hubble telescope's camera.

Using the Hubble Telescope's Advanced Camera (ACS) and Wide Field Camera 3 (WFC3), a cluster of three galaxies was imaged. As shown in the image, the two galaxies have merged, scientists say, just as the two galaxies in the upper right appear to be interacting with each other, it is, in fact, stars. Its long trails and the gas spreading from both of them gives the impression that these two have just collided with each other very fast. In the lower left of the image is the bowling-ball-sized galaxy. Scientists say that the interaction between two galaxies occurs over a long time period, however, rarely will the galaxies collide with each other. These galaxies are so close to each other in space that they form a cluster, which scientists have named NGC 7764A. The mass between these galaxies has caused the formation of a shape at the end that, from the point of view of our solar system, resembles the starship known as the USS Enterprise from Star Trek. This gr...
