Solar System: Things To Know This Week

Solar System: Things to Know This Week

Here are a few things you should know about our solar system this week:

1. The Bright and the Beautiful

In its lowest-altitude mapping orbit, at a distance of 240 miles (385 kilometers) from Ceres, Dawn has provided scientists with spectacular views of the dwarf planet, especially of its bright, young, hexagonal craters like Haulani.

2. Mars Needs Brains

NASA is soliciting ideas from U.S. industry for designs of a Mars orbiter for potential launch in the 2020s. The satellite would provide advanced communications and imaging, as well as robotic science exploration, in support of NASA’s Journey to Mars. This effort seeks to take advantage of industry capabilities to improve deep space, solar electric propulsion-enabled orbiters.

3. Seeing Double

NASA measured a solar flare from two different spots in space, using three solar observatories. During a December 2013 solar flare, three sun-observing spacecraft captured the most comprehensive observations ever of an electromagnetic phenomenon called a current sheet.

4. Set a Course for Europa

This artist’s rendering shows NASA’s Europa mission spacecraft, which is being developed for a launch in the 2020s. The mission would place a spacecraft in orbit around Jupiter in order to perform a detailed investigation of the giant planet’s moon Europa—a world that shows strong evidence for an ocean of liquid water beneath its icy crust and which could host conditions favorable for life.

5. Go Deep

Jupiter is huge, powerful and spectacular. But what lies hidden inside the giant planet? The Juno mission arrives at Jupiter in July to help us find out. Join Dr. Fran Bagenal to learn more about the mission and how it plans to delve deep into Jupiter’s secrets this year.

Solar System: Things to Know This Week

Here are a few things you should know about our solar system this week:

1. Gearing Up for a Grand Finale

There’s just a year left until the Cassini mission begins its Grand Finale – the final phase of its mission, during which the spacecraft will dive repeatedly between the planet and the rings. To get ready, the Cassini team has launched an enhanced, mobile device-friendly version of the mission website. The site includes information about Cassini, Saturn, the moons and the rings – but it also tells the human stories behind one of the most ambitions expeditions of all time.

2.Caught in Transit

On Monday, May 9, the planet Mercury will cross directly in front of the sun, an event that hasn’t occurred since 2006 and won’t happen again until 2019. Find out how to watch HERE.

3. A Moon for Makemake

Our Hubble Space Telescope has spotted a small, dark moon orbiting Makemake (pronounced “MAH-kay MAH-kay). Make make is the second brightest icy dwarf planet – after Pluto – in the faraway Kuiper Belt.

4. The Age of the Aquarids

The Eta Aquarid meteor shower is the first of two showers that occur each year as a result of Earth passing through dust released by Halley’s Comet. This year, it should peak on the night of May 5/6. Get tips for watching HERE.

5. The Southern Lights of Saturn

On May 4, Cassini will reach periapse, the closest point to Saturn in the spacecraft’s orbit. At about this time, Cassini’s cameras will monitor Saturn’s south polar aurorae, and also image the bright limb of the planet to better understand its upper haze layers.

Psychedelic Pluto : New Horizons scientists made this false color image of Pluto using a technique called principal component analysis to highlight the many subtle color differences between Plutos distinct regions.
