NASA Plans New Moon Mission

NASA is set to work with American companies to design and develop new reusable systems, in a major step to land astronauts on the surface of the Moon.
NASA is planning to test new human-class landers on the Moon beginning in 2024, with the goal of sending crew to the surface in 2028.
Through upcoming multiphased lunar exploration partnerships, NASA will ask American companies to study the best approach to landing astronauts on the Moon and start the development as quickly as possible with current and future anticipated technologies.

Aircraft-like Black Box Systems in Trains

The Indian Railways is soon going to install aircraft-like black box systems in trains.
The Indian Railway has started installing Loco cab audio video recording system (LCAVR) / Crew Voice/Video Recording System (CVVRS) in Diesel and Electric locomotives.
This system provides invaluable data to investigators which will help them in understanding the sequence of events leading up to an accident and for identifying operational issues and human factors.

Eco-friendly Algae Curtains

Two European architects have developed plant-filled plastic curtains designed to turn building facades into "living walls" that help purify dirty air.
The curtains contain a maze-like network of tubes filled with microscopic algae, which like all green plants remove carbon dioxide from the air while pumping out oxygen via the carbon-sequestering process known as photosynthesis.
Air flows into the bottom of the curtains and rises through the tubes, feeding the microalgae along the way.

Messaging Feature by Instagram

Instagram has added the new communication feature to its app. A new microphone button has been added to the photo and video app.
Unlike WhatsApp where you first choose the recipient, on Instagram you can first record the message and then share it with a single contact or group.
Additionally, these voice messages appear in the receiver`s chat window as a Wav file and don`t disappear after being listened to.

Signs of Water Found on Asteroid Bennu

NASA's OSIRIS-REx spacecraft has discovered ingredients for water on a relatively nearby skyscraper-sized asteroid, a rocky acorn-shaped object that may hold clues to the origins of life on Earth.
The probe, on a mission to return samples from the asteroid to Earth for study, was launched in 2016. Bennu, roughly a third of a mile wide, orbits the sun at roughly the same distance as Earth.
There is concern among scientists about the possibility of Bennu impacting Earth late in the 22nd century.
