NASA calls the Perseids meteor shower the best of the year, thanks to its many bright meteors that streak across the sky in late summer. This year, the shower reaches its peak on August 12, before dawn.
hi,a hi from 2021 .-.

THE YEAR OF AMONG US
oh yeah,i forgot,theres also a pandemic that has spread around all the world and killed millions of people and left us in cuarentine for 4 months straight.
But that's not important,,,
ESA Solar Orbiter flies past Venus . It will use its gravity and draw its orbit closer to the Sun in a mission to make the first photos of the Sun's poles.
NASA launched the European Space Agency's Solar Orbiter in February. Five months later, the probe beamed back the closest photos ever taken of the sun.
Over its seven-year mission, the orbiter is expected to take the first photos of the sun's poles and capture images of the largest holes in its atmosphere. The spacecraft is also designed to pinpoint the origins of space weather and track eruptions on the sun in near-real time.
In order to see the sun's poles, the orbiter must fly past Venus and use the planet's gravity to swing itself into an orbit that takes it above the plane of our solar system. It will do so three more times over the course of its mission.
NASA's Near Earth Asteroid Scout (NEAScout) mission is launched
NEA Scout is an exciting new mission that was recently selected by NASA’s Advanced Exploration Systems (AES) by a team from the Jet Propulsion Laboratory and Marshall Space Flight Center. This innovative, low-cost concept will map an asteroid and demonstrate several technological firsts, including being the first CubeSat to reach an asteroid.
Before sending astronauts to any new space environments, it is important to send robotic scouts to survey the destination and learn about the risks and challenges they may pose to future human explorers. Near-Earth Asteroid Scout, or NEA Scout, will perform reconnaissance of an asteroid using a CubeSat and solar sail propulsion, which offers navigation agility during cruise for approaching the target. Propelled by sunlight, NEA Scout will flyby and observe a small asteroid (<300 feet in diameter), taking pictures and observing its position in space, the asteroid’s shape, rotational properties, spectral class, local dust and debris field, regional morphology and regolith properties. NEA Scout’s observations will directly assist in retiring the unknowns related to human exploration of asteroids and planetary small bodies. The data collected will enhance the current understanding of asteroidal environments and will yield key information for future human asteroid explorers.
This is YOU from the past.I just want to say that if you are an army brat then congratulations.
if you are not than ALLAH has a better plan for you.
May love finds you,
when you least expect,
where you least expect.
Costa Rica deserves a huge round of applause, and perhaps even a high five, for managing to produce all of its electricity from renewables for 75 days straight. According to the state-owned Costa Rican Electricity Institute (ICE), the country hasn’t had to burn fossil fuels to supply the grid with electricity so far in 2015, a stretch that has never been previously attained by any nation. Of course, we don’t mean all of their energy has come from renewables as their vehicles, for example, still use fossil fuels, but what they have achieved is extremely laudable.
“The year 2015 has been one of electricity totally friendly to the environment for Costa Rica,” the ICE said in a statement last week.
As reported by Think Progress, the country’s clean streak is predominantly attributable to heavy rains experienced this year, which have kept four of the main hydroelectric power stations busy. In fact, these have been churning out so much energy that virtually all of 2015’s electricity demands have been met through these plants, according to Quartz. The remainder of the country’s grid requirements have been met through a combination of wind, solar, biomass and geothermal energy.
In Latin America, Costa Rica ranks second in terms of electricity service provision (behind Uruguay) with a household coverage rate of 99.4%. And thanks to this boon in renewables, citizens are shortly due a 12% drop in electricity rates this year and given the reserves so far accumulated, this downward trend is predicted to continue in the second quarter, Latin American Herald Tribune reports.
Costa Rica is determined to become carbon-neutral by 2021, which seems an achievable goal given that the country is currently meeting around 94% of its energy needs from renewables. Around 68% is sourced from hydroelectric power plants, followed by geothermal energy that contributes about 15%. This dedication to clean energy combined with the country’s broader environmental policies has meant that Costa Rica has been consistently ranked in the top five eco-friendly countries worldwide, according to The Telegraph.
Although what Costa Rica is achieving is something to aspire towards, it won’t be easy for many countries to follow in their footsteps. The tropical country is adorned with a string of active volcanoes that allow for geothermal projects, such as the $958 million endeavor approved last year. Costa Rica also experiences high rainfall and features a mountainous landscape, both of which are ideal for the generation of renewable energy. Furthermore, the country is able to invest substantial amounts into environmental issues due to the fact that it ditched its military back in 1948.
While Costa Rica’s dependence on renewables is commendable, it also has its drawbacks and leaves the country vulnerable to the effects of climate change. A drought, for example, would impede their ability to produce electricity from hydropower stations. Furthermore, hydroelectric dams can have negative effects on fish populations.
Costa Rica is, of course, not the only country dedicated to going green. The EU has set renewable energy goals for 2020, but Sweden, Bulgaria and Estonia managed to meet these eight years ahead of schedule. China is also investing a substantial amount in renewables, which has been proposed to be a key factor in the fact that CO2 emissions stalled last year. Bonaire, a small Caribbean island, also currently produces almost all of its energy from renewable sources.
