New Horizons Fine-Tunes Its Course for MU69

A little goes a long way—especially when you’re traveling 51,000 mph! On Feb. 1, 2017 NASA’s New Horizons spacecraft performed a 44-second thruster burn that adjusted its course by just under 1 mph toward its next target, the Kuiper Belt object 2014 MU69.

“One mile per hour may not sound like much,” said mission Principal Investigator Alan Stern, “but over the next 23 months, as we approach MU69, that maneuver will add up to an aim point refinement of almost six thousand miles (10,000 kilometers).”

New Horizons made its closest pass by Pluto on July 14, 2015. It will perform a similar flyby of the much smaller MU69 on Jan. 1, 2019.

Here’s What It Would Look Like to Land on Pluto’s Heart

What would it look like to approach Pluto for a landing? Perhaps some day in the future a robotic mission will do exactly that and we’ll know for sure, but for now we have to use our imaginations…luckily we do have some incredible images of Pluto to help with the details, thanks to NASA’s New Horizons spacecraft!

Using images and data acquired by New Horizons during its historic close pass by Pluto on July 14, 2015, researchers have assembled a video simulating an approach to Pluto’s surface, centering in on a “landing site” along the edge of Sputnik Planum: the heart-shaped “sea” of nitrogen ice cells.

Are You Ready For Pluto?

New Horizons sure is! With just over two weeks to go before the first-ever (and I repeat: EVER!) visit to Pluto and its family of moons the excitement has really ramped up exponentially, especially considering the increasingly detailed views of Pluto and Charon that the spacecraft has been capturing on approach. No longer just a couple of bright pixels against a background of stars, the two worlds now show actual detail that can be easily discerned. In other words, things are getting REAL!

It’s only going to be getting better from here – and quickly. As Principal Investigator Dr. Alan Stern said, “There’s only one Pluto flyby planned in all of history, and it’s happening next month!”

New Horizons Has Caught Its First Color Pic of Pluto

Pluto and Charon imaged by New Horizons on April 9, 2015

Pluto and Charon imaged by New Horizons on April 9, 2015

In a historic first – just one of many that will be made over the next several months, to be sure! – the New Horizons spacecraft captured its first color image of Pluto and its partner/satellite Charon on April 9 from a distance of 71 million miles – about equivalent to that between Venus and the Sun. The orange blobs above are the two worlds locked in an orbital dance a mere 12,200 miles apart… that’s 20 times less than the distance between Earth and the Moon!

The image was captured with New Horizons’ “Ralph” instrument, a Multispectral Visible Imaging Camera (MVIC) built for the mission by Ball Aerospace (which is a spinoff of the same company that became famous in the U.S. for its glass canning jars.)

Ralph is one of six science instruments aboard New Horizons; it is paired with “Alice,” an ultraviolet imaging camera. (Think Ralph and Alice Kramden.) When New Horizons makes its close pass by Pluto and Charon on July 14 these cameras will capture details of the icy worlds like never before seen.

Closing In on Planet Pluto: an Interview with New Horizons PI Alan Stern

After more than nine years of traveling through space the New Horizons spacecraft is now in the home stretch of its journey, with less than 120 days and 143 million kilometers to go before it makes its historic flyby of the Pluto system on July 14. It will be the first time we get a good close-up look at the distant world which had for over seven decades held reign over the frozen edges of our Solar System as the outermost planet, much like its namesake governed the cold darkness of the mythological Greek underworld.

Discovered on February 18, 1930, the ninth planet Pluto lost its “full” planetary status in August 2006 as the result of a highly-contested decision by the International Astronomical Union (IAU) to create a new class of “dwarf planets,” of which Pluto, Ceres, and the then-recently-discovered Eris became charter members. Seven months after New Horizons launched, the edict did not sit well with both many members of the planetary science community and the public, who were suddenly informed that little Pluto just didn’t measure up and had to be let go… nothing serious, right?

Wrong. It was a serious scientific issue for many people, and especially for Dr. Alan Stern, Associate Vice President of Space Science and Engineering at the Southwest Research Institute in Boulder, CO and principal investigator of New Horizons. And understandably so – Dr. Stern’s planetary exploration mission is on its way to Pluto after all, and what it’s expected to encounter is far more complex than what’s implied by the diminutive moniker of “dwarf planet” (which, oddly enough, was coined by Stern himself in 1990.)

I had a change to talk briefly with Dr. Stern on Friday, March 13 – which, incidentally, was the 85th anniversary of Pluto’s first announcement to the world – and got some insight from him on the mission and what we can expect from the upcoming flyby, as well as his views on the whole “planet/dwarf planet” thing. (And yes, it certainly does still matter!)
