China Sends New Astronomical Satellite

China sent a new astronomical satellite shaped like a lotus into space to observe mysterious transient phenomena in the universe that flicker like fireworks.
The satellite named Einstein Probe (EP), which uses new X-ray detection technology inspired by the functioning of a lobster eye, was launched by a Long March-2C carrier rocket from the Xichang Satellite Launch Centre in southwest China's Sichuan Province.
Weighing about 1.45 tonnes and as large as a full-size SUV, the satellite is shaped like a lotus in full bloom and features 12 petals and 2 stamens.
The 12 petals are 12 modules consisting of wide-field X-ray telescopes (WXT), while the two "stamens" consist of 2 modules of follow-up X-ray telescopes (FXT).

NASA Sends Five Payloads to the Moon on Astrobotic's Peregrine Lander

The first American spacecraft to attempt to land on the Moon in more than half a century was successfully launched.
United Launch Alliance's Vulcan Centaur, lifted off from Cape Canaveral Space Force Station in Florida for its maiden voyage, carrying Astrobotic's Peregrine Lunar Lander.
The Peregrine lander is targeted to land February 23 at Sinus Viscositatis, a lunar feature outside of the hardened lava Gruithuisen Domes on the near side of the Moon. Similar natural structures on Earth require large volumes of water to form, leading scientists to believe that this landing site may contain evidence of water on the Moon.

India's First Solar Observatory Aditya L1 Reaches Its Destination Halo Orbit

India's first solar observatory Aditya-L1 achieved a major milestone as it reached the Halo Orbit's L1 point, a unique spot in space outside the orbit of the Moon to give a clear view of the Sun throughout the year. Prime Minister Narendra Modi congratulated the achievement.
Objects positioned at L1 remain in a stable configuration relative to the Earth and the Sun, making it an advantageous location for certain types of satellites, like those used for solar observations or monitoring space weather. However, maintaining a satellite at L1 requires constant adjustments due to gravitational perturbations from other celestial bodies.

ISRO Tests Fuel Cell on PSLV-C58's POEM3 Platform Successfully

The Indian Space Research Organisation (ISRO) achieved a significant milestone by successfully testing a 100 W class Polymer Electrolyte Membrane Fuel Cell based Power System (FCPS) in its orbital platform, POEM3. This remarkable feat took place aboard the PSLV-C58 mission, marking a crucial step in the assessment of fuel cell technology for future space missions.
The primary objective of the experiment was to evaluate the operation of Polymer Electrolyte Membrane Fuel cells in the challenging environment of space. Additionally, the mission aimed to gather valuable data to inform the design of power systems for upcoming space endeavours.

ISRO to Tie-up with Elon Musk's SpaceX to Launch Satellite

ISRO's (Indian Space Research Oragnisation) commercial arm NewSpace India Limited (NSIL) announced that it will use Elon Musk-led SpaceX's Falcon-9 for one of its mission launches later this year (2024).
The mission to launch GSAT-20, is slated for a launch in second quarter of 2024. This mission will be the first time ISRO will be using a SpaceX rocket to launch one of its satellites.
