ISRO GSLV-F10 / GISAT-1 MISSION

 ISRO is preparing for the launch of GISAT-1 

GISAT 1

Indian Space Research Organization (ISRO) is preparing for the launch of the Earth-monitoring satellite 'GISAT-1'. 

This mission will start at a time when the PSLV-C51 mission is also to be executed on 28 February. 'GISAT-1' will be launched through GSLV-F10 rocket. 

The satellite was scheduled to be launched on March 5 last year, but was postponed a day ahead of schedule due to technical reasons.

 Space Secretary and ISRO Chairman K.K. Sivan told PTI-language that the technical issues had been resolved and the delay in launch was due to the Covid-19 lockdown which affected normal operations. ISRO sources said the launch could now be done from the Sriharikota Space Center in late March or early April.

 According to the Space Agency, 'GISAT-1' will continue to monitor the Indian subcontinent at regular 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.

A 4 metre diameter Ogive shaped payload fairing is being flown for the first time in this GSLV flight. This is the fourteenth flight of the GSLV.

Operating from geostationary orbit, GISAT-1 will facilitate near real time observation of the Indian sub continent, under cloud free condition, at frequent intervals.

human spaceflight missions and the Chandrayaan-3 lunar landing mission

 ISRO has updated deadlines for dispatches of its human spaceflight missions and the Chandrayaan-3 lunar landing following COVID-19-related postponements. 

The Indian Space Research Organization (ISRO) was focusing on August 2022 for the dispatch to check the 75th commemoration of Indian autonomy. Anyway the main human spaceflight showing will currently trail a second uncrewed experimental drill presently got ready for 2022-23, executive K Sivan has said. 

ISRO is focusing on a first uncrewed dry run in December this year. The mission will include human-appraised Geosynchronous Satellite Launch Vehicle Mark III rocket with an adjusted upper stage viable with a team module and group get away from framework, as indicated by Times of India. 

The first uncrewed mission was at first wanted to dispatch in December 2020, following the proper declaration of the Gaganyaan project in August 2018. India had toward the end of last year expressed that the Gaganyaan venture will be "marginally postponed" because of COVID-19. 

The initially manned mission will convey three space travelers with one reinforcement. Four pilots chose for the program are partaking in space traveler preparing in Russia. 

India is meaning to join Russia, the United States and China as the solitary nations to have accomplished free human spaceflight capacities. The nation is additionally at this beginning phase looking past low Earth circle. 

India's Department of Space as of late delivered the draft "People in Space Policy" into the public area for remarks and proposals in front of potential bureau endorsement. 

The report expresses that the Humans in Space Policy "focuses on supported human presence in space as an instrument for improvement, advancement and encourage joint efforts in arrangement with public interests." 

In seeking after the draft the Department of room would be required to "characterize [a] long haul guide for supported human presence in low earth circle and undertaking investigation missions past low earth circle." 

Fundamental advances for empowering supported human presence in LEO and past as expressed to incorporate regenerative life emotionally supportive networks, meeting and docking frameworks, inflatable territories and extravehicular action suits. 

Using global participation, creating biological systems, empowering business venture and improving public contribution are likewise noted as key assignments. 

Second lunar landing endeavor deferred 

Chandrayaan-3, India's third mission to the moon, is probably going to slip to 2022, ISRO executive K Sivan disclosed to Press Trust of India news office. 

The mission will include a lander and a little meanderer like Chandrayaan-2, yet no orbiter. 

The 2019 Chandrayaan-2 mission effectively put an orbiter around the moon however the arrival endeavor finished in loss of correspondences notwithstanding an ostensible plummet down to a height of around two kilometers. 

Chandrayaan-3 is relied upon to focus on a similar landing site, around 70.9 degrees south of the lunar equator. The Chandrayaan-2 orbiter will work as a correspondences hand-off for the Chandrayaan-3 lander. 

On the off chance that fruitful Chandrayaan-3 could make India the fourth nation to effectively delicate land on the moon. 

K Sivan told press that the mission and its arranged achievement will shape the premise of ISRO interplanetary missions. India is likewise arranging a Venus orbiter for dispatch in 2024. 

India is in the interim getting ready for the dispatch of the PSLV-C51 (the 53rd Polar Satellite Launch Vehicle mission) from Satish Dhawan Space Center, Sriharikota, at 10:24 a.m. Eastern, Feb. 28. 

The Amazonia-1 optical earth perception satellite of National Institute for Space Research (INPE) of Brazil is the essential payload. It will be joined by 18 more modest traveler satellites. 

The mission will be India's first dispatch of 2021, following a COVID-19-hit 2020.

nothing can be taken for granted when you get to mars there's a lot of things we just don't know space always has a way of throwing us curveballs and surprising us i mean until we get the data that says we're on the ground safely i'm gonna be worried that we're not gonna make it entry descent and landing is often referred to as the seven minutes of terror because it takes about seven minutes to get from the top of the atmosphere of mars to the ground safely the spacecraft has to do all of this by itself there are many things that have to go right to get perseverance onto the ground safely there's a lot counting on this this is the first leg of our sample return relay race there's a lot of work on the line starting about 10 minutes before atmospheric entry we get rid of really the spacecraft part of of the rover that's been supporting us we come screaming in to the martian atmosphere at 12 to 13 000 miles per hour and the heat shield is what dissipates all that initial energy through friction the vehicle will continue actually flying itself through the atmosphere it's sort of like a transforming vehicle that went from spacecraft and now it's kind of like an aircraft actively guiding itself when we're going slow enough we deploy a parachute the biggest supersonic parachute we've ever sent to another planet it's critical for slowing down the vehicle perseverance entry descent and landing borrows heavily from that of curiosity but fundamentally perseverance is a different rover she's bigger she has different instruments we've added a lot of smarts on the inside to make it more capable so that it can deal with the landing site that we've given the science team identified jezreel crater as basically an ancient lake bed and one of the most promising places to look for evidence of ancient microbial life and to collect samples for future return to earth the problem is it's a much more hazardous place to land you look at jezreel all you see is danger how do we go to a site that we never thought was safe enough to go to before so the heat shield which has protected us all the way through entry is no longer necessary we need to get that off so that we can actually see the ground and we can see the ground in a couple different ways perseverance will be the first mission to use terrain relative navigation so while it's descending on the parachute it will actually be taking images of the surface of mars and determining where to go based on what it sees this is finally like landing with your eyes open having this new technology really allows perseverance to land in much more challenging terrain than curiosity or any previous mars mission could amongst the rocks and the craters and the cliffs these things are hazardous to the rover but these are the things that are interesting to the scientists once perseverance has figured out where she is we jettison the back shell and parachute and light up our rockets those rockets help us steer to a safe landing spot that's nearby that descent stage takes us all the way down to about 20 meters off the ground that's when we start the skycrane maneuver [Music] once the rover has hit the ground the descent stage will cut loose from the rover and fly away to a safe distance surviving that seven minutes is really just the beginning for perseverance its job right being the first leg of sample return to go look for those signs of past life on mars all that can't start until we get perseverant safely to the ground and then that's when the real mission begins 

China Mars mission: Tianwen-1 spacecraft enters into orbit

 China says it has successfully put its Tianwen-1 mission in orbit around Mars

It's the first run through the nation has figured out how to get a space apparatus to the Red Planet and comes a day after the United Arab Emirates achieved a similar accomplishment. 

Tianwen-1, or "Inquiries to Heaven", involves an orbiter and a wanderer. 

Designers will stick around for their chance prior to despatching the wheeled robot to the surface yet the assumption is that this will occur in May or June. 

Wednesday's circle inclusion underlines again the quick advancement China's space program is making. 

It follows December's great mission to recover rock and soil tests from Earth's Moon - by any measure an exceptionally unpredictable endeavor. 

Tianwen-1's main goal, especially the surface component, will be no less testing. 

Its five-ton rocket stack, comprised of orbiter and wanderer, was dispatched from Wenchang spaceport in July, and voyaged almost a large portion of a billion km to meet with the Red Planet. 

Architects had arranged a 14-minute slowing down consume on the orbiter's 3,000-newton engine, with the assumption that this would diminish its 23km/s speed adequately to permit catch by Mars' gravity. 

The move was computerized; it must be. Radio orders presently require 11 minutes to cross the 190 million km currently isolating Earth from Mars. 

It ought to have put Tianwen-1 of every an underlying enormous circle that comes in as close as 400km from the surface and out similar to 180,000km. 

This will be managed over the long haul to get more tight and more circularized.

Rather than the Emiratis' live TV inclusion on Tuesday, China decided to report the circle addition at Mars exclusively after it had happened. 

It was clear right off the bat, nonetheless, that occasions were continuing as they ought to in light of the fact that novice radio devotees could tune in across Tianwen-1's signs, and they could see every achievement in the move was being accomplished. 

China is following the procedure utilized by the Americans for their fruitful Viking landers during the 1970s. The thought at that point was to make circle solitary later send a robot to the surface. 

A time of surveillance will presently follow yet Tianwen-1's essential decision for a score is a level plain inside the Utopia sway bowl only north of Mars' equator. 

The meanderer, which still can't seem to be named, looks a ton like the US space organization's (Nasa) Spirit and Opportunity wanderers from the 2000s. It gauges some 240kg and is controlled by overlay out sunlight based boards. 

A tall pole conveys cameras to take pictures and help route; five extra instruments will help survey the mineralogy of neighborhood shakes and search for any water-ice. 

A key test will be the ground-entering radar, which ought to have the option to detect land layers at profundities of numerous meters. 

This surface examination is truly just a large portion of the mission, nonetheless, on the grounds that the orbiter that has been shepherding the meanderer will likewise consider the planet, utilizing a set-up of seven distant detecting instruments. 

Like past satellites, this space apparatus will notice attributes of the high air and analyze the constructions and structure of the surface. High-and medium-goal cameras should restore some noteworthy pictures. 

Tinawen-1 is one of three missions showing up at Mars this February. 

The UAE's Hope test made it securely into space on Tuesday. One week from now, Nasa will endeavor to put another of its enormous meanderers on a superficial level.

Scientist has taken new fusion and done pointer

Dr Fatima Ebrahimi has invented a new fusion rocket thruster concept which could power humans to Mars and beyond.

A woman scientist working with the US government has prepared a new fusion card that can be used to transport a human to Mars by 10 times (compared to the existing used ornaments). Dr. who works at the Princeton Pledge Physics Laboratory (PPPL), USA. Fatima Ibrahim said that the new ready made shoots the magnet parts through the magnetic field. (Image- PPPL)

The physicist who works for the US Department of Energy's Princeton Plasma Physics Laboratory (PPPL) designed the rocket which will use magnetic fields to shoot plasma particles - electrically charged gas - into the vacuum of space.

According to Newton's second and third laws of motion, the conservation of momentum would mean the rocket was propelled forwards - and at speeds 10 times faster than comparable devices.

The marble that is currently being used involves shooting parts through an electric field. But the use of magnetic fields in new clothes made by Fatima will help to gain more momentum.

According to the Daily Mail report, Fatima says that he had been working on his idea since 2017. Explain that fusion is called the power that is produced by sun or stars. 

Scientists have been working on fusion technology in Japan for a long time to help achieve electricity for the future.

At the Princeton Pluz Physics Laboratory in the US and the National Energy Research Scientific Computing Center, it was observed that higher speeds could be achieved with the new plot thruster concept. Gaining more speed during the initial journey of the spacecraft can make it easier for humans to reach Mars.

There, it usually takes several months and many years to travel long distances in space because chemical cap engines travel at comparatively slow speeds. But experts say that it may be possible to achieve higher speeds through magnetic field thrusters.

However, the use of fusion technology in frames is not new. But some new things have been used in Fatima's design that makes it different. For example, the thrust can be reduced or increased by changing the magnetic field.
