This 19-year-old could keep astronauts safe from space trash

  This 19-year-old could keep astronauts safe from space trash There are thousands of pieces of trash floating above the Earth. When we think of space, we often think of the vast emptiness of the next frontier. Unfortunately, that’s starting to change. There are more than 500,000 pieces of man-made trash floating above the Earth making “the next frontier” more of a hostile obstacle course for astronauts and satellites. The more we launch up there, the more difficult space travel becomes.

NASA 's next mission will give us InSight into Mars' interior. InSight is blasting off this week. The lander aims to rest in an isolated spot and detect " marsquakes ," which NASA described as "like a flashbulb that illuminates the structure of the planet 's interior."

"We want to use seismology to learn why Mars formed the way it did, and how planets take shape in general." When rocks crack or shift, they give off seismic waves that bounce throughout a planet .

Nasa has launched a spacecraft to land on Mars and explore the mysterious insides of the red planet.

A robotic geologist armed with a hammer and quake monitor is rocketing towards Mars after the successful launch of the craft on Saturday.

In a twist, Nasa launched the Mars InSight lander from California rather than Florida’s Cape Canaveral.

It was the first interplanetary mission ever to depart from the US West Coast, drawing pre-dawn crowds to Vandenberg Air Force Base and rocket watchers down the California coast into Baja.

The spacecraft will take more than six months to get to Mars and start its unprecedented geological excavations, travelling 300 million miles to get there.

InSight will dig deeper into Mars than ever before – nearly 16 feet – to take the planet’s temperature.

It will also attempt to make the first measurements of ‘Marsquakes’, using a high-tech seismometer placed directly on the Martian surface.

Also aboard the Atlas V rocket: A pair of mini-satellites, or CubeSats, meant to trail InSight all the way to Mars in a first-of-its-kind technology demonstration.

Pakistan sees 'hottest April day ever on Earth'

  Pakistan sees 'hottest April day ever on Earth' The hottest April temperature ever witnessed on Earth may have been recorded in Pakistan after meteorologists saw the weather reach a scorching 50.2C (122.4F).  The 1.1 million people who live in the southern district of Nawabshah observed the blistering heat on Monday, with some meteorologists calling it a record.On Twitter, Etienne Kapikian of Meteo France, said it was the hottest April temperature ever recorded in Pakistan and the entire continent of Asia.

When InSight does take off , NASA wants very few Earth germs on the spacecraft . Earthquakes are caused by shifts in tectonic plates on our planet , whereas “ Marsquakes ” are likely fueled by magma moving under the surface or the vibrations of cracks in the crust.

The one billion dollar mission involves scientists from the US, France, Germany and elsewhere in Europe.

“I can’t describe to you in words how very excited I am… to go off to Mars,” said project manager Tom Hoffman from Nasa’s Jet Propulsion Laboratory in Pasadena, California. “It’s going to be awesome.”

Nasa has not put a spacecraft down on Mars since the Curiosity rover in 2012. 

The US is the only country to successfully land and operate a spacecraft at Mars. Only about 40% of all missions to Mars from all countries – orbiters and landers alike – have proven successful over the decades.

If all goes well, the three-legged InSight will descend by parachute and engine firings onto a flat equatorial region of Mars – believed to be free of big, potentially dangerous rocks – on November 26.

With high temperature even ozone levels increase in Delhi, experts call it sunburn for lungs

  With high temperature even ozone levels increase in Delhi, experts call it sunburn for lungs With high temperature even ozone levels increase in Delhi, experts call it sunburn for lungsThis week, the Central Pollution Control Boards (CPCB) National Air Quality Index (NAQI) recorded Ozone as the primary pollutant in Delhi on three days May 4th, 2nd and 1st. This is when, generally, only PM (Particulate Matter) 10 and PM 2.5 emerge as the primary pollutants in the national Capital on most days, besides Nox and CO (Carbon Monoxide) rarely.

NASA 's " Marsquake " Detecting Spacecraft Arrives at Launch Site. It will be listening for " marsquakes .' The spacecraft will be propelled into space aboard a United Launch Alliance Atlas V-401 rocket. How can I help look for other planets ?

“It will use the seismic waves generated by marsquakes to develop a map of the planet ’s deep InSight had originally been scheduled to blast off in March 2016, although NASA suspended its The @NASAInSight lander will be the 1st spacecraft to take the Red Planet ’s vital signs & study its deep

Once down, it will stay put, using a mechanical arm to place the science instruments on the surface.

“This mission will probe the interior of another terrestrial planet, giving us an idea of the size of the core, the mantle, the crust and our ability then to compare that with the Earth,” said Nasa’s chief scientist, Jim Green.

“This is of fundamental importance to understand the origin of our solar system and how it became the way it is today.”

InSight’s chief scientist, Bruce Banerdt of JPL, said Mars is ideal for learning how the rocky planets of our solar system formed 4.5 billion years ago. Unlike our active Earth, Mars has not been transformed by plate tectonics and other processes, he noted.

Over the course of two Earth years – or one Martian year – scientists expect InSight’s three main experiments to provide a true 3-D image of Mars.

The lander is equipped with a seismometer for measuring Marsquakes, a self-hammering probe for burrowing beneath the surface, and a radio system for tracking the spacecraft’s position and planet’s wobbly rotation, thereby revealing the size and composition of Mars’ core.

“InSight, for seismologists, will really be a piece of history, a new page of history,” said the Paris Institute of Earth Physics’ Philippe Lognonne, lead scientist of the InSight seismometer.

Problems with the French-supplied seismometer kept InSight from launching two years ago. California was always part of the plan.

Nasa normally launches from Cape Canaveral, but decided to switch to California for InSight to take advantage of a shorter flight backlog.

2010 WC9: Asteroid the Size of the Statue of Liberty Set to Skim Past Earth .
The asteroid was mysteriously "lost" to astronomers for a number of years.Estimated to stretch about 170-400 feet across, asteroid 2010 WC9 should pass at about half the distance to the Moon at its closest approach at 6:05 p.m. ET. It’s not a particularly big asteroid, but this will be a pretty close encounter for a space rock of this size.
