Japan to launch first wooden satellite by 2023

 

Wooden satellites, which burn completely on atmospheric re-entry without releasing harmful aluminium-rich particles, are being developed in Japan.


WHY WOODEN SATELLITE

  • According to researchers, not only would wooden satellites be better for the environment, they will also go a long way in paving new and simpler designs, if used to make a craft's outer shell.
  • Since electromagnetic signals pass more easily through wood, scientists said, the antennas could be placed within rather than outside the satellite body.
  • The Japanese team of experts have also revealed that their first wooden satellite will be ready to launch into space by the year 2023.

Did You Know

  • At present, space satellites are typically made up of aluminium and its alloys, as the metal is relatively cheap, lightweight and durable.
  • Though aluminium-based components have the benefit of being able to withstand both extremes of temperature and bombardment by space radiation, they add to the thousands of space junk around the Earth, if they are left in orbit, becoming a hazard to other satellites and rockets.

Educate Girls To Fight Climate Change: Malala

  Keeping girls in school and taking young climate leaders seriously are keys to tackling climate change, Nobel Peace Prize winner  Malala  Yousafzai said on Friday. Speaking to a virtual panel,  Malala , 23, said educating girls and young women, particularly in developing countries, would give them a chance to pursue green jobs and be part of solving the climate crisis in their communities. "Girls' education, gender equality and climate change are not separate issues. Girl's education and gender equality can be used as solutions against climate change,"  Malala  told an online event by British think-tank Chatham House. Before the COVID-19 pandemic, some 130 million girls worldwide were already out of school, according to the United Nations cultural agency UNESCO, which said more than 11 million may not return to classes after the pandemic. "When we educate girls ... they can become farmers, conservationists, solar technicians, they can fill other green job...

Post 7% Cut In Emissions,Experts Warn Of Rebound

Image
  Coronavirus restrictions led to a record 7% fall in global carbon emissions last year, but the drop will be short-lived unless efforts to phase out fossil fuel are intensified, a study by scientists in the journal Nature Climate Change said. The study by scientists from institutions in Australia, Britain, France, Norway and the United States, confirmed preliminary estimates from May last year that global CO2 emissions from fossil fuels fell by 7%, or 2.6 billion tonnes, to 34 billion tonnes. On Tuesday, the International Energy Agency said global CO2 emissions dropped by 5.8% in 2020. The study in Nature Climate Change analysed daily CO2 emissions across 71 countries and six economic sectors, using data from daily electricity use and mobility tracking services. To keep the global temperature rise to 1.5-2 degrees Celsius (2.7 degrees Fahrenheit) this century, emissions must decrease by 1-2 billion tonnes a year, the United Nations says. "When fossil fuel infrastructure is put in...

Now, a low-cost portable machine to grab plastic bags

A team of students has developed an innovative portable and lowcost machine, which efficiently collects discarded plastic bags. The machine, created by six final year engineering students from the Sona College of Technology in Salem, Tamil Nadu, is currently undergoing rigorous trials on the streets, within the municipal limits of the steel and textiles town. "The plastic waste collecting device is mounted on a sturdy frame with an infra-red sensor attached to a mobile vacuum chamber. It is capable of sensing plastic on the roads and attract it," project leader TV Kishore Kumar said.The idea and the execution. The Idea and execution Kumar, along with classmates N Javeeth Khan, R Akash, S Lokeshwar, R Dinesh Babu and R Ilavarasan, were inspired to create this device, after a call by the PM to make India plastic-free. The team integrated a shredder as an add-on accessory, which shreds the collected plastic bags. This shredded material was then mixed to concrete as a replacement...
