50 years on, mobile phones continue to change our lives

The first call on a mobile phone was a victory in the competition. On April 3, 1973, Motorola engineer Martin Cooper contacted his AT&T rival and proposed a 2.4-pound prototype. He wanted his competitor to be the first to know that his team had successfully completed a working mobile phone.

This spirit of competition and innovation has pushed technology up and changed society so much that it is now hard to imagine life without mobile phones.

Fifty years ago, the idea of ​​calling someone on the phone in your pocket was unthinkable—until it was. Since the first cell phone call on April 3, 1973, technology has continued to change the way people communicate.

Mobile devices will never go away because people always want to stay connected, says futurist Brian David Johnson of Arizona State University. “The more technology we have, the more human we become,” says Mr. Johnson.

But there’s a downside, says Joanne Orlando, a digital wellbeing specialist based in Sydney, Australia. Most of the people she talks to tell her they are “addicted” to their cell phones.

She suggests asking yourself how your phone can work for you and not the other way around. “How,” she asks, “is it possible to have such an amazing thing and not use it properly?”

The first call on a mobile phone was a victory in the competition. On April 3, 1973, Motorola engineer Martin Cooper called his AT&T rival on a phone that weighed 2.4 pounds and was about the size of a brick. He wanted his competitor to be the first to know that his team had successfully completed a working mobile phone.

This was just the beginning.

Fifty years ago, the idea of ​​calling someone on the phone in your pocket was unthinkable—until it was. Since the first cell phone call on April 3, 1973, technology has continued to change the way people communicate.

How did cell phones originate and spread?

The mobile phone Mr. Cooper used to call was a DynaTAC 8000X, and a 30-minute call required a 10-hour charge. It will be another ten years before it becomes commercially available. In 1983, consumers were finally able to buy it for $3,995 ($12,000 in today’s money).

In 1992, IBM released the first smartphone, or phone, that could function as a computer. Variations followed: downsized, flip phone and Blackberry. In 2007, Apple combined the touch screen and other technologies with its iPhone, popularizing the smartphone as a pocket computer. The phone has become a camera and a device for all sorts of applications, not just calls and text messages. Development continued under the leadership of Apple and Google’s rival Android platform.

Japanese lander most likely crashed, Ispace reports

Published

on

A Japanese company has lost contact with a small robotic spacecraft it was sending to the moon. Analysis of data from the craft indicates that it ran out of fuel on its final approach and instead of landing, it crashed softly into the lunar surface.

After the launch of the main engine, the lander Hakuto-R Mission 1, built by the Japanese company Ispace, descended from the lunar orbit. About an hour later, at 12:40 pm ET Tuesday, the about 7.5-foot-tall lander was due to land in Atlas Crater, which formed in the 54-mile-wide northeast quadrant of the moon’s near side.

But after the moment of landing, no signal was received from the spacecraft. In a video broadcast live by the company, a shroud of silence shrouded the control room in Tokyo, where Ispace engineers, mostly young from around the world, looked worriedly at their screens.

In a statement released on Wednesday morning in Japan, the company said Ispace engineers noticed that the estimated remaining fuel capacity was “at the low end and the rate of descent increased dramatically shortly thereafter.”

In other words, the spacecraft ran out of fuel and crashed.

After that, communication with the spacecraft was lost. “Based on this, it has been determined that there is a high probability that the lander eventually made a hard landing on the lunar surface,” the company said.

The investigation will now have to determine why the spacecraft appears to have misjudged its altitude. Analysis shows that he was still high up when he should have been on the ground.

In an interview, Takeshi Hakamada, chief executive of Ispace, said that he was “very, very proud” of the result nonetheless. “I’m not disappointed,” he said.

With data from the spacecraft, the company will be able to apply “lessons learned” to its next two missions, Mr Khakamada said.

The Hakuto-R spacecraft launched in December and took a circuitous but energy-efficient route to the Moon, entering lunar orbit in March. For the past month, engineers have been testing the lander’s systems before embarking on a landing attempt.

The Ispace lander could be the first step towards a new space exploration paradigm, with governments, research institutes and companies sending scientific experiments and other payloads to the Moon.

The start of this lunar transport transition will now have to wait for other companies later this year. Two commercial landers built by US companies and funded by NASA are scheduled to launch to the moon in the coming months.

NASA established its Commercial Lunar Payload Servicing Program, or CLPS, in 2018 because buying private spacecraft flights for tools and equipment to the Moon promises to be cheaper than building your own vehicles. In addition, NASA hopes to stimulate new commercial industry around the moon, and competition between lunar companies is likely to drive down costs even further. The program was modeled in part on similar efforts that successfully provided transportation to and from the International Space Station.

For now, however, NASA has little to show for its own efforts. The first two missions later this year, by Pittsburgh-based Astrobotic Technology and Houston-based Intuitive Machines, are years behind schedule, and some of the companies selected by NASA to participate in the CLPS missions have already gone out of business.

Ispace is planning a second mission using a lander of much the same design next year. In 2026, the larger Ispace lander is due to carry NASA payloads to the far side of the Moon as part of the CLPS mission led by the Draper Laboratory in Cambridge, Massachusetts.

Two countries – Japan and the United Arab Emirates – lost payloads aboard the lander. The Japanese space agency JAXA wanted to test a two-wheeled transformable lunar robot, and the Mohammed bin Rashid Space Center in Dubai sent a small rover to explore the landing site. Each of them would be the first robot explorer of this country on the lunar surface.

Other payloads included a solid-state battery test module from NGK Spark Plug Company, an AI onboard computer, and 360-degree cameras from Canadensys Aerospace.

During their space race more than 50 years ago, the United States and the Soviet Union successfully sent robotic spacecraft to the surface of the Moon. Most recently, China has landed an undamaged spacecraft on the Moon three times.

However, other attempts were unsuccessful.

Beresheet, a project of the Israeli non-profit organization SpaceIL, crashed in April 2019 when a crew sent to the spacecraft inadvertently turned off the main engine, causing the spacecraft to plummet and disintegrate.

Eight months later, the Indian lander Vikram veered off course about a mile above the surface during a landing attempt, then silently left.

If the Ispace lander does crash, it may take some time to figure out from the telemetry sent from the spacecraft to figure out what happened. NASA’s Lunar Reconnaissance Orbiter was eventually able to locate the crash sites of Bereshit and Vikram, and may also be able to find M1’s resting place in Atlas Crater.

Ispace isn’t the only private space company struggling in the first few months of 2023. New rocket models built by SpaceX, ABL Space Systems, Mitsubishi Heavy Industries, and Relativity all failed on their first flights, although some have gone further into space than others. . Virgin Orbit’s last rocket launch failed and the company later filed for bankruptcy, although it continues to work on a new launch.

At the same time, the frequency of launches is higher than ever: the SpaceX Falcon 9 rocket has already made dozens of successful launches in 2023. The Arianespace rocket also sent the European Space Agency probe to Jupiter.
