NASA's Near Earth Asteroid Scout (NEAScout) mission is launched
Overview
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.

Costa Rica is the first carbon-neutral country
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.

NASA DART spacecraft will perform kinetic impact deflection of a hazardous Asteroid
The Double Asteroid Redirection Test (DART) mission is directed by NASA to the Applied Physics Laboratory (APL) with support from several NASA centers: the Jet Propulsion Laboratory (JPL), Goddard Space Flight Center (GSFC), Johnson Space Center (JSC), Glenn Research Center (GRC), and Langley Research Center (LaRC).
DART is a planetary defense-driven test of technologies for preventing an impact of Earth by a hazardous asteroid. DART will be the first demonstration of the kinetic impactor technique to change the motion of an asteroid in space. The DART mission is in Phase C, led by APL and managed under NASA’s Solar System Exploration Program at Marshall Space Flight Center for NASA’s Planetary Defense Coordination Office and the Science Mission Directorate’s Planetary Science Division at NASA Headquarters in Washington, DC.
The binary near-Earth asteroid (65803) Didymos is the target for the DART demonstration. While the Didymos primary body is approximately 780 meters across, its secondary body (or “moonlet”) is about 160-meters in size, which is more typical of the size of asteroids that could pose the most likely significant threat to Earth. The Didymos binary is being intensely observed using telescopes on Earth to precisely measure its properties before DART arrives.
The DART spacecraft will achieve the kinetic impact deflection by deliberately crashing itself into the moonlet at a speed of approximately 6.6 km/s, with the aid of an onboard camera (named DRACO) and sophisticated autonomous navigation software. The collision will change the speed of the moonlet in its orbit around the main body by a fraction of one percent, but this will change the orbital period of the moonlet by several minutes - enough to be observed and measured using telescopes on Earth.
Once launched, DART will deploy Roll Out Solar Arrays (ROSA) to provide the solar power needed for DART’s electric propulsion system. The DART spacecraft will demonstrate the NASA Evolutionary Xenon Thruster – Commercial (NEXT-C)solar electric propulsion system as part of its in-space propulsion. NEXT-C is a next-generation system based on the Dawn spacecraft propulsion system, and was developed at NASA’s Glenn Research Center in Cleveland, Ohio. By utilizing electric propulsion, DART could benefit from significant flexibility to the mission timeline while demonstrating the next generation of ion engine technology, with applications to potential future NASA missions.
The DART spacecraft launch window begins in late July 2021. DART will launch aboard a SpaceX Falcon 9 rocket from Vandenberg Air Force Base, California. After separation from the launch vehicle and over a year of cruise it will intercept Didymos’ moonlet in late September 2022, when the Didymos system is within 11 million kilometers of Earth, enabling observations by ground-based telescopes and planetary radar to measure the change in momentum imparted to the moonlet.

ESA Solar Orbiter spacecraft will take the first photos of the Sun’s polar regions and images of the Solar Wind like never before
Solar Orbiter, a new collaborative mission between ESA (European Space Agency) and NASA to study the Sun, launched at 11:03 p.m. EST Sunday on a United Launch Alliance Atlas V rocket from Launch Complex 41 at Cape Canaveral Air Force Station in Florida.
At 12:24 a.m. Monday, mission controllers at the European Space Operations Centre in Darmstadt, Germany, received a signal from the spacecraft indicating that its solar panels had successfully deployed.
In the first two days after launch, Solar Orbiter will deploy its instrument boom and several antennas that will communicate with Earth and gather scientific data. Solar Orbiter is on a unique trajectory that will allow its comprehensive set of instruments to provide humanity with the first-ever images of the Sun's poles. This trajectory includes 22 close approaches to the Sun, bringing the spacecraft within the orbit of Mercury to study the Sun and its influence on space.
“As humans, we have always been familiar with the importance of the Sun to life on Earth, observing it and investigating how it works in detail, but we have also long known it has the potential to disrupt everyday life should we be in the firing line of a powerful solar storm,” said Günther Hasinger, ESA director of Science. “By the end of our Solar Orbiter mission, we will know more about the hidden force responsible for the Sun’s changing behavior and its influence on our home planet than ever before."
Solar Orbiter will spend about three months in its commissioning phase, during which the mission team will run checks on the spacecraft's 10 scientific instruments to ensure they are working properly. It will take Solar Orbiter about two years to reach its primary science orbit.
Solar Orbiter combines two main modes of study. In-situ instruments will measure the environment around the spacecraft, detecting such things as electric and magnetic fields and passing particles and waves. The remote-sensing instruments will image the Sun from afar, along with its atmosphere and its outflow of material, collecting data that will help scientists understand the Sun's inner workings.
During the mission's cruise phase, which lasts until November 2021, the spacecraft's in-situ instruments will gather scientific data about the environment around the spacecraft, while the remote-sensing telescopes will focus on calibration to prepare for science operations near the Sun. The cruise phase includes three gravity assists that Solar Orbiter will use to draw its orbit closer to the Sun: two past Venus in December 2020 and August 2021, and one past Earth in November 2021.
Following its Earth gravity assist, Solar Orbiter will begin the primary phase of its mission – leading up to its first close pass by the Sun in 2022 – at about a third the distance from the Sun to Earth. Throughout its mission, Solar Orbiter will use successive Venus gravity assists to draw its orbit closer to the Sun and lift it out of the ecliptic plane.
Solar Orbiter’s unique orbit will bring the spacecraft out of the plane that roughly aligns with the Sun's equator where Earth and the other planets orbit. Spacecraft launched from Earth naturally stay in this plane, which means that telescopes on Earth and telescopes on satellites have limited views of the Sun's north and south poles.
A previous ESA-NASA mission, Ulysses, launched in 1990, achieved an inclined orbit giving scientists their first measurements of the space around the Sun in this critical region. Unlike Ulysses, Solar Orbiter carries cameras that will provide the first-ever images of the Sun's poles. This vital information will help scientists fill in the gaps in models of the Sun's magnetic field, which drives the Sun's activity.
"Solar Orbiter is going to do amazing things. Combined with the other recently launched NASA missions to study the Sun, we are gaining unprecedented new knowledge about our star," said Thomas Zurbuchen, NASA’s associate administrator for Science at the agency’s headquarters in Washington. “Together with our European partners, we’re entering a new era of heliophysics that will transform the study of the Sun and help make astronauts safer as they travel on Artemis program missions to the Moon."
ESA's European Space Research and Technology Centre in the Netherlands manages the development effort. The European Space Operations Center in Germany will operate Solar Orbiter after launch. Solar Orbiter was built by Airbus Defense and Space. The spacecraft contains 10 instruments. Nine were provided by ESA member states and ESA. NASA provided one instrument, the Solar Orbiter Heliospheric Imager (SoloHI), and an additional sensor, the Heavy Ion Sensor, which is part of the Solar Wind Analyzer instrument suite.
Solar Orbiter complements a fleet of NASA Heliophysics spacecraft observing the star we live with and its effects on the space we travel through.

Because Jesus promised me better than this.
Dear me,
First of all, you better be staying true to your last name, always. Right now, I'm not in a healthy environment, and I'm exhausted from hurting both physically and emotionally. It's not that I just want to change only my life: I pray that the Lord changes his, too. Yesterday was my very first day of work at the candy shop after no work at all (due to school) for over a year, and it was the best day, until I had to go home. If you are reading this, please believe, understand, and acknowledge that I'm writing this to you because I believe in you--God is making miracles out of your messes, yet again. I'm witnessing His mercy, right this second. This is the start of your second stretch. Abuse does NOT define you. You are no longer a victim: YOU ARE A SURVIVOR. I just know that you'll be better off than I am now. I am going to do all I can possibly do to make sure that you live the life you deserve. No matter where you are, what you're going through--no matter how old you are--you are going to make it, I promise. Lucy, Charlotte, and Grandma Margaret are watching you from above, while Yeager, Ella, Morgan, Doc Holiday, and Wyatt are protecting you at your temporary home. All I have right now is my disabled, rescue dogs, but they will lead me to you. I didn't rescue them; they rescued me. Don't forget about the nursing home where you last saw Grandma laugh, and never forget to listen to "Wagon Wheel." Take care of your dad. Remember what Grandma taught you and practice her teachings daily. Never forget that you want a pastel, yellow jeep with a cheetah-print, fuzzy interior (LOL). Bring your love of mathematics wherever you go. You are, indeed, beautiful and blonde, yet these physical qualities do not define your knowledge. Yes, you are, indeed, blonde and beautiful, but you are brilliant. NASA is waiting for you (also, fight for Pluto to be a planet lol:). Never stop writing, even if no one is ever going to read what you wrote. Lastly, go out there and be extraordinary. You are a game changer. You are going to experiencing happiness that you never knew existed BECAUSE JESUS PROMISED ME BETTER THAN THIS. P.s. don't forget about the 400,00 children in the U.S. foster care system (not including street kids and/or runaways); advocate for them. Be the person I need right now. P.s.s. continue to write on this time capsule, every single time you open it. Love, Nicole Nice
