Experience the encounter of New Horizons with a new world of mobile apps

On January 1, 2019 at 12:33 pm EST (0533 GMT), a robot envoy of humanity will fly past the outer solar system on an unprecedented world. The New Horizons spacecraft, which had a highly successful encounter with Pluto on July 14, 2015, received an expanded mission to explore a remote Kuiper Belt facility called the 2014 MU69 and unofficially named Ultima Thule.

At one billion miles from Pluto, this is the farthest spaceship in human history. At the time of the next approach, New Horizons will travel at a speed of 32,279 miles per hour (or 51

,948 kilometers per hour) and will be only 3,500 kilometers from the object. This is three times closer than Pluto ever has. The sun is a tiny point of light that is more than 43 astronomical units away (AU, the mean distance between Earth and Sun). Nevertheless, we expect exciting images of the reddish, two-lobed (or possibly two-body) object that helps us understand the formation and evolution of our solar system.

Astronomy and space enthusiasts will celebrate New Year's Day with a flyby at a special time. But the radio signals from New Horizons and the tantalizing new images they'll bring us will arrive at Earth's receivers only 6 hours later. In this issue of Mobile Astronomy, we'll discuss how to make the most of this historic event. You can use your favorite mobile device to read a fascinating book about the mission, see NASA TV coverage of the event in the NASA app, which starts at midnight on December 31 (when the government shutdown is over, and NASA TV back in action – otherwise) Johns Hopkins & # 39; Applied Physics Laboratory has a live feed), and you can experience the encounter virtually with the free Pluto Safari app from the manufacturers of the SkySafari 6 Astronomy app.

  The Pluto Safari app homepage provides real-time status updates for the mission. On the voting page, users can read the arguments for and against the Pluto classification by the IAU as dwarf planets, vote on the issue, and see the voting results.

The Solar System Simulator in Pluto Safari is known to users of the SkySafari app series. It is used for the timeline and location features in the app. The Timeline page displays information about each milestone in the New Horizons mission. This allows the user to go through each phase of the mission – starting in 2006 through the Jupiter Gravitation Wizard, various distance milestones, first images of objects, the encounter with Pluto and the Ultima Thule flyby. In any case, the date and time as well as the distance from New Horizons to Earth and to Pluto are given.

A View button launches the simulated 3D view of each Timeline event from the perspective of New Horizons in Space. In this mode, you can squeeze and zoom the display to change the size of the objects, move your finger over the finger to reorient the view, or use the up and down arrows to change the distance to the spacecraft. (The current distance is displayed in the upper-left corner of the screen.)

  The Pluto Safari timeline option allows you to review all the milestones of the New Horizons mission, from the launch of the 2015 Pluto encounter to the Ultima Thule flyby on January 1, 2019. Tapping on the view icon will open an annotated, dynamic 3D simulation of each event that you can zoom in and out of. The clock icon opens timers to run the event virtually, in real time or at different rates.

Most simulations start by default with time. Tapping the clock icon at the bottom of the screen will open a time-out control panel that allows you to fast-forward or rewind the time, continuously or incrementally. Touch one of the two innermost arrows to pause the flow of time. Touch one of the outermost arrows to continue. The time flow rate is controlled by selecting each time or date parameter, such as month or hour. If you're passing the event, revert to the time or just go back to the Timeline page and touch the View icon to restart the event.

For a clear overview of each encounter, the options displayed on the screen vary. For example, the Pluto flyby shows the orbits of Pluto's moons, while the Ultima Thule flyby shows the orbits of all planets and Ultima Thule, as well as the trajectory of the spacecraft through them.

The Location page offers seven ways to view the current mission status of New Horizons. One of them shows the position of the spacecraft and the Ultima Thule in the sky when viewed from your location on Earth. On January 1, 2019, her position is 0.25 degrees northwest of the star Al Baldah (also called 41 Sagittarii). This part of the sky will go down shortly after the evening sun in early January, but the objects are too close to the sun to be watched, and they will be far below the horizon for western hemisphere observers at the time of the flyby. A second view of the sky is reserved for Pluto, which will be even closer to the Sun on January 1, 2019.

  The "Kuiper Belt Object (KBO)" view in the "Locations" menu brings the exciting new science that emerges from the outer sunlight system. In addition to displaying the trajectory of the New Horizons and the position of the tiny Ultima Thule, it shows the totally different orbits of the many Pluto-class objects discovered so far.

The other five simulated views are three-dimensional models of the spacecraft and the solar system. One shows the trajectory of New Horizons, Ultima Thule and its orbit, as well as the orbits of the main planets, all of which are viewed from high above the plane of the solar system. Another view shows the approach of the probe to Ultima Thule from a vantage point near the plane of the solar system inward.

The most interesting option, the Kuiper Belt Objects View, contains the basic elements of the other two views, but adds 9 of the major KBOs discovered so far, including Eris, the object that led to Pluto's downgrade to the dwarf planet. You can also use the Pinch option to create Sedna's enormous orbit. The tilt of the model to bring the orbits of the classical planets into a single plane will show how different the inclinations of these distant worlds are.

The last two simulations focus on Pluto. As before, the option to zoom in and out of the model as well as turnaround time will allow you to virtually experience the flyby. Having your device handy when New Horizons passes Ultima Thule makes you feel like you're coming along.
