NASA Verifies The Trends For Global Warming Through Their Study

Researchers of NASA have conducted a new study, which has verified the accurate figures with respect to Global Warming. The team made use of measurements of the skin temperature of the Earth, which was taken by an infrared measurement system based on a satellite, known as AIRS from the year 2003 to 2017. They made a comparison of these with analysis based on station, regarding the anomalies with regard to the surface air temperature. The principal analysis carried out was the Goddard Institute for Space Studies Surface Temperature Analysis. What they found was a high level of consistency between the two sets of data over the last 15 years.

Lead author, Dr Joel Susskind while making a comment on the study said that the data from AIRS tend to complement GISTEMP. It is because they lie at a much higher spatial resolution compared to GISTEMP. Both sets of data clearly demonstrate that the earth’s surface has been suffering from global warming over this period of time. This has significance due to the intensity of interest in the detail as to how estimates regarding the change in global and regional temperature get constructed from the data regarding surface temperature. Plus, the manner in which the known imperfections in the raw data get handled. The data from AIRS tends to reflect skin temperature that exists at the surface of the ocean, land and the regions covered by snow or ice.

Dr Gavin Schmidt, the co-author from the Institute for Space Studies of NASA said that their findings clearly revealed that the data based on the surface might well underestimate the changes in temperature occurring in the Arctic. This goes to show, the warming that takes place at the poles might well be happening more swiftly than it was thought earlier.

Beresheet Does Not Manage To Land Safely On The Moon

Beresheet Does Not Manage To Land Safely On The Moon

On Thursday evening, Israel was almost successful in getting lunar history rewritten. Unfortunately, it fell short after the spacecraft Beresheet did not manage to make a safe landing on the surface of the Moon. Millions of people all across the world had tuned in to watch the live telecast of the SpaceIL vessel, carrying the flag of Israel and a small Bible. It was set to descend to the Mare Serenitatis of the Moon. The moment was such that the State of Israel had sought to become only the fourth member of a prestigious pool of nations to complete the formidable task of landing up a spacecraft on the surface of the moon. The SpaceIL went over to lose contact with the spacecraft just minutes before it was set to complete the landing.

The spacecraft landing was only achieved before by the United States, Russia, and China. This was after covering a journey of 6.5 million km for a period of seven weeks since Beresheet. It is quite an ambitious project that is developed by SpaceIL and Israel Aerospace Industries. The spacecraft was blasted off from Cape Canaveral, Florida with the SpaceX rocket on board on 22nd February. For a period of 48 days, the ground crew of Beresheet had watched,m monitored and went on to execute each and every movement of the spacecraft right from a control centre at the Yehud headquarters of IAI.

Once they were in a position to go down, the landing operation split into two phases of decreased horizontal velocity, followed by vertical velocity. The commencement to descend had started but ultimately failed to land after contact got lost with the main engine of the spacecraft. Thus it led to a loss of altitude and a crash landing in a subsequent manner.
