ISRO to launch GISAT-1 geo-imaging satellite on March 5

Taking the partial success of Chandrayaan-2 in its stride, the Indian Space Research Organisation (ISRO) has announced its plans to launch a new geo-imaging satellite called GISAT-1 into space on March 5 at 5:43pm (IST). The space agency will launch the new satellite from Satish Dhawan Space Centre (SDSC) SHAR in Sriharikota using the GSLV-F10 (Geosynchronous Satellite Launch Vehicle). The satellite is designed to help observe the Indian subcontinent under ‘cloud-free conditions’ at frequent intervals.

“Weighing about 2268 kg, GISAT-1 is the first state-of-the-art agile Earth observation satellite which will be placed in a Geosynchronous Transfer Orbit by GSLV-F10. Subsequently, the satellite will reach the final geostationary orbit using its onboard propulsion system,” says ISRO about its new satellite. The satellite is equipped with multi-spectral (visible, near infra-red and thermal), multi-resolution (50 m to 1.5 km) imaging instruments.

According to the Indian space agency, GISAT-1 has a diameter of four metres and its payload fairing bears the shape of an ogive. With the launch of GISAT-1, ISRO will use its GSLV for the fourteenth time. Once deployed, GISAT-1 can capture selected field images every five minutes and the entire Indian landmass every thirty minutes at a spatial resolution of 50m. GISAT-1 has a planned lifespan of 7 years.

In related news, ISRO Chairman K Sivan announced at the beginning of the year that the space agency would develop a Chandrayaan-3 to accomplish what Chandrayaan-2 couldn’t apart from working on the Gaganyaan crewed lunar mission. Chandrayaan-3 is scheduled to take flight to the moon towards the end of the current year or at the beginning of the next. Gaganyaan, on the other hand, will take as many as four Indian astronauts to the moon sometime in 2022.

PS5 unboxing videos show how huge the console is

To say that Sony has been a bit coy when it comes to the PlayStation 5 would be a bit of an understatement. The company only recently announced the India pricing of the console and now finally we have unboxings of the console going live and one thing is pretty clear - The console is HUGE!  So what do you get in the box? Well… besides the console itself (and the manuals), you get: DualSense controller USB Type-C charging cable for the controller HDMI 2.1 cable Power cable for the console (no bulky adapter/box) Plastic stand Now the plastic stand is used if you place the console on its side. As there is no flat surface on either side of the console, the stand will ensure that it remains still. But you can also place it when propping up the console vertically. However, it does seem like the PS5 can stand on its own vertically if need be. IGN’s unboxing video gives you a good idea of how to place the stand. All of the unboxing videos mention the size of the console because it is pr...
