As Isro works on human spaceflight, a glimpse of challenges from the past

Image
On December 28, the Government of India okayed India’s first human spaceflight programme at a cost of Rs 9,023 crore. The programme will attempt to launch three Indian astronauts to low-Earth orbit for as many as seven days. If the mission – slated to happen in 2022 – succeeds, India will become only the fourth country in the world able to launch astronauts into space. It is not yet clear what the astronauts will do in space. The Indian Space Research Organisation (ISRO), which is leading the programme, has said they will perform some science experiments on their first flight but nothing of what comes after. But there’s no doubt that there are a lot of possibilities, and that astronauts – Indian and otherwise – have lots left to do in the coming decades. They’re crucial in everything from extraterrestrial mining to Mars missions, space diplomacy to weaponisation,. In this sense, it is important for space organisations to maintain a keen awareness of their spacefarers’ f...

Nasa launching laser satellite in September to study Earth's changing ice

ICESat-2 will improve upon Nasa's 15-year record of monitoring the change in polar ice heights Technology News : Nasa is launching a laser-armed satellite next month that will measure -- in unprecedented detail -- changes in the heights of Earth's polar ice to understand what is causing ice sheets to melt fast. In recent years, contributions of melt from the ice sheets of Greenland and Antarctica alone have raised global sea level by more than a millimeter a year, accounting for approximately one-third of observed sea level rise, and the rate is increasing. Called the Ice, Cloud and Land Elevation Satellite-2 (ICESat-2), the mission is scheduled to be launched from Vandenberg Air Force Base in California on September 15, Nasa said in a statement late on Thursday. ICESat-2 will measure the average annual elevation change of land ice covering Greenland and Antarctica to within the width of a pencil, capturing 60,000 measurements every second. "The...
