BEIJING: China successfully launched an automated cargo resupply spacecraft to rendezvous with an orbiting module, in the second of a series of missions needed to complete its first permanent space station.
The Tianzhou-2, or “Heavenly Vessel” in Chinese, blasted off via a Long March-7 Y3 rocket from the Wenchang Space Launch Centre on the southern island of Hainan, the China Manned Space Engineering Office said.
Tianzhou-2 is the second of 11 missions needed to complete China’s first self-developed space station around 2022 and follows the launch of the key module Tianhe in late April.
The three-module space station will rival the only other station in service, the International Space Station (ISS), which is backed by countries including the United States, Russia and Japan. China was barred from participating in the ISS by the United States.
Tianzhou-2 will autonomously dock with Tianhe, which will provide supplies for future astronauts as well as propellant to maintain its orbital altitude. The rocket’s launch was postponed this month due to technical reasons.
The first cargo spacecraft Tianzhou-1 was sent to refuel a space lab – Tiangong-2 – three times in 2017, as a test of the technologies needed to support the construction of the space station. Both Tiangong-2 and an earlier space lab Tiangong-1 have been deorbited in recent years.
Next year, China will launch the two other core modules — Wentian and Mengtian — using the Long March 5B, its biggest and most powerful space transport vehicle.
That rocket, capable of sending 25 tonnes of payload into low Earth orbit, was a source of worry earlier in May as it re-entered the atmosphere after delivering Tianhe into orbit.
Media reports warned of an “uncontrolled” re-entry of the rocket’s core stage, reviving memories of debris from the flight of the first Long March 5B in May 2020, which damaged buildings when it landed in Ivory Coast.
Remnants from the rocket finally fell harmlessly in the Indian Ocean, but China drew criticism for not being transparent about the timing of the debris re-entry and predictions of its trajectory.
From June until 2022, four manned spacecraft and four cargo spacecraft will also be launched, by the smaller Long March-7 and 2F rockets, which have a maximum low Earth payload of 14 tonnes and 8.8 tonnes, respectively.
Before cloud storage, USB drives, and smartphones, there was the 1.44 MB Floppy Disk—a symbol of the early digital age that transformed how the world stored and shared information. For millions of people, the floppy disk was their first experience with digital storage, carrying school assignments, office documents, software programs, games, and precious memories.
Today, this iconic piece of technology has become a collectible artifact, representing an era that laid the foundation for the modern digital world.
The Legacy of the 1.44 MB Floppy Disk
Introduced as one of the most widely used storage mediums of its time, the 3.5-inch floppy disk became a global standard throughout the 1980s and 1990s. Although its storage capacity of 1.44 MB may seem tiny by today’s standards, it was once considered revolutionary.
Students carried their projects on floppy disks. Businesses stored important files and records. Computer enthusiasts exchanged software and games using these small plastic squares that became an essential part of everyday life.
A Nostalgic Tribute for the Digital Generation
The 1.44 MB Floppy Disk Heritage Frame transforms this historic technology into a premium display piece. Carefully mounted within an elegant 8×12-inch frame, it serves as a reminder of a simpler and pioneering era of computing.
Whether displayed in an office, study room, technology lab, or home, the framed floppy disk sparks conversations about innovation, creativity, and the remarkable journey of digital technology.

The era which we are praising
today is the product of the intellects of many millennium. Those are the gems
of intellect that worked out at that time when there were no scientific
resources. Those people have observed their surroundings and have produced
resources for humanity. The intellectual Muslims have contributed to every
field and their contributions are most valuable. Today all the advancements are
based on the discoveries and inventions of ancient scientists both Muslims and
Non-Muslims. Modern scientists are working and producing technological items that
are also based on the ideas of ancient ones.
Al-Hassan Ibn al-Haytham of Basra
is known to be the pioneer of Optics. He was the product of the Golden Age of
Muslim Civilisation that was a creative time period and brought out many
far-reaching advancements in the field of science, mathematics, and medicine.
He was the greatest Muslim physicist and one of the greatest students of optics
of all time. He was inspired by the works of other great philosophers and
scientists who were before him such as Aristotle, Euclid, Al-Kindi, Banu Musa,
Ibrahim Ibn Sinan, and Ibn Sahl. Ibna al-Haytham based his theories on the work
of Greek physician Galen. He is the one who introduced the methods of
verification, testing, and experimentation for the exploration of truth. He has
written books as well and in one of his books he says: “If learning the truth is the scientist’s goal . . . then he must make
himself the enemy of all that he reads.”
He was the person who has given
the concept of how vision works. And he has written a book about the “Book of
Optics” in which he has illustrated the eyes and optic nerves. He has drawn
images of eyes which have been used by the modern scientist to understand and
to produce lenses and other optics items. Al-Haytham used a dark chamber to
explore the nature of light and vision. Through this experiment, he observed
that light entering through a small hole would travel straight and would
project an image onto the opposite wall. From this concept, modern cameras have
been designed.
Today, if we can have different
lenses and glasses to replace or improve our vision artificially and can
capture our every moment, is all because of Al-Haytham. The world is grateful
for all his contributions.
