If low approach velocities are desired for orbiters or landers, ballistic flight times to Pluto and other similar distant Kuiper Belt Object-like targets like Triton can be very long – a generation. Even so, the New Horizons (NH) flyby took nearly 10 years to reach Pluto with the help of a Jupiter gravity assist and still the approach velocity was about 14 km/s.
How can one land on or orbit Pluto in a reasonable mission time without many hundreds of millions of dollars in nuclear power sources for low-thrust propulsion, or an exotic propulsion system that could take decades and many millions of dollars to develop, or a next generation launch vehicle and a massive chemical propulsion system? Also, can a Pluto mission be accomplished under the aegis of a NASA New Frontiers Program?
SAN ANTONIO, Texas, March 16, 2021 (Southwest Research Institute PR) — One of the most profound discoveries in planetary science over the past 25 years is that worlds with oceans beneath layers of rock and ice are common in our solar system. Such worlds include the icy satellites of the giant planets, like Europa, Titan and Enceladus, and distant planets like Pluto.

Atomic Planar Power for Lightweight Exploration (APPLE) E. Joseph Nemanick The Aerospace Corporation Santa Monica, Calif.
The Atomic Planar Power for Lightweight Exploration (APPLE) is an enabling architecture for deep solar system missions on low mass, fast transit space platforms. We explore an alternative vehicle architecture that integrates a long-lived, peak power capable, rechargeable, and modular power system with solar sail propulsion, and examine the new missions this architecture enables.
New Horizons Mission Update by Alan Stern Principal Investigator
New Horizons is healthy and performing perfectly as it flies deeper and deeper into the Kuiper Belt! Recently we conducted an engineering review of the spacecraft to “trend” how it was working compared to when it was launched. The result was amazing: Every system and science instrument aboard New Horizons is working as well as it did when we lifted off, more than 14 years and almost 5 billion miles ago. As mission principal investigator I could not be prouder — the men and women who designed, built and tested New Horizons literally created a masterpiece of American workmanship that will likely be able to perform and explore for many more years and many more miles!
SAN ANTONIO, Texas (SwRI PR) — NASA has funded Southwest Research Institute to study the important attributes, feasibility and cost of a possible future Pluto orbiter mission. This study will develop the spacecraft and payload design requirements and make preliminary cost and risk assessments for new technologies.
LAUREL, Md. (JHUAPL PR) — Years before a team of researchers proposed a mission called New Horizons to explore the dwarf planet Pluto, NASA’s Hubble Space Telescope had already made initial observations of the world at the dim outer fringes of our celestial neighborhood. Over many years, Hubble’s pioneering observations repeatedly accomplished what ground-based telescopes could not — imaging features on Pluto’s surface, finding new Plutonian moons, and tracking down a destination to visit after Pluto — an even tinier, icy object in a vast region of small worlds beyond the orbit of Neptune called the Kuiper Belt.
After a stellar flyby on Pluto, NASA’s New Horizons is set to make the first flyby of Kuiper belt object on New Year’s Eve as it zips past Ultima Thule. Now you can beam a greeting to the plucky probe that’s four billion miles from home at this website. Don’t delay. It’s a limited-time offer.

As America celebrated Independence Day on July 4, 2015, many members of the Johns Hopkins University Applied Physics Laboratory (APL) team that had guiding NASA’s New Horizons spacecraft toward the first ever exploration of Pluto took a little time off to relax before their lives became very busy.
After a 9.5-year long journey, the spacecraft was only 10 days out from its closest approach to the mysterious dwarf planet. All the secrets Pluto had kept hidden for 85 years since Clyde Tombaugh discovered in 1930 were about to be revealed.
And then the unthinkable happened. Controllers suddenly lost contact with the spacecraft as they were loading the final software needed to guide it through week-long flyby sequence set to begin in only three days. When communications were restored, controllers discovered to its horror that the program and all the supporting files they had spent months uploading had been wiped from the spacecraft’s computer.
New Horizons Team Celebrates Four Decades of Discovery on Pluto’s Large, Amazing Moon
Laurel, Md. (JHUAPL PR) — The largest of Pluto’s five moons, Charon, was discovered 40 years ago today by James Christy and Robert Harrington at the U.S. Naval Observatory in Flagstaff, Arizona – only about six miles from where Pluto itself was discovered at Lowell Observatory. They weren’t even looking for satellites of Pluto – Christy was trying to refine Pluto’s orbit around the Sun.
MOJAVE, Calif. (MASP PR) — Alan Stern will be at the Stuart O. Witt Event Center at the Mojave Air and Space Port on Tuesday, June 12, 2018 from 4:00 pm – 5:00 p.m. promoting his new book, “Chasing New Horizons”. He will speak for around 30 minutes and then will chat and sign books.
Seating is limited. If you plan to attend, Please RSVP to email@example.com no later than Thursday, June 7th.
An international fleet of spacecraft will be launched in 2018 to explore the Moon, Mars, Mercury and the Sun. Two sample-return spacecraft will enter orbit around asteroids while a third spacecraft will be launched to search for asteroids that contain water that can be mined.
NASA will also launch its next exoplanet hunting spacecraft in March. And the space agency will ring in 2019 with the first ever flyby of a Kuiper Belt object.
And, oh yes, Elon Musk is launching his car in the direction of Mars. (more…)
Video Caption: Using actual New Horizons data and digital elevation models of Pluto and its largest moon Charon, mission scientists have created flyover movies that offer spectacular new perspectives of the many unusual features that were discovered and which have reshaped our views of the Pluto system – from a vantage point even closer than the spacecraft itself.
This dramatic Pluto flyover begins over the highlands to the southwest of the great expanse of nitrogen ice plain informally named Sputnik Planitia. The viewer first passes over the western margin of Sputnik, where it borders the dark, cratered terrain of Cthulhu Macula, with the blocky mountain ranges located within the plains seen on the right. The tour moves north past the rugged and fractured highlands of Voyager Terra and then turns southward over Pioneer Terra — which exhibits deep and wide pits — before concluding over the bladed terrain of Tartarus Dorsa in the far east of the encounter hemisphere.
Digital mapping and rendering were performed by Paul Schenk and John Blackwell of the Lunar and Planetary Institute in Houston.
An airship for Mars, two spacecraft capable of exploring the hellish environment of Venus, and a fusion-powered orbiter and lander for Pluto are three of the planetary-related research projects recently funded by theNASA Innovative Advanced Concepts (NIAC) program.
In all, NIAC funded eight advanced projects focused on Mars, Venus and Pluto in its latest annual funding round. The space agency also funded two proposals aimed at identifying and extracting resources on planets, moons and asteroids. (more…)

Imagine a craft that could enter Pluto’s atmosphere at 14 km/s and deliver a 200 kg lander to the surface using aerodynamic drag and just a few kg of propellant.
Pluto’s surface pressure is just 10 millionths of Earth’s, but its atmosphere is about 7 times higher than Earth’s and its volume is about 350 times the volume of Pluto itself. Over a several hundred kilometer entry distance, this ultra-low ballistic coefficient craft can dissipate over 99.999% of its initial kinetic energy, resulting in a terminal velocity comparable to or less than past planetary landers or rovers.
With this architecture, the total propellant requirement for landing on Pluto is less than 3.5 kg! After making science measurements at its initial landing site, the lander switches to “hopper” mode, taking advantage of the low gravitational acceleration (0.063 gee) and a modest propellant store to literally hop, skip, and jump around the surface, sometimes kilometers at a time, investigating features of interest.
The proposed concept would enable in-situ surface science at Pluto with low overall mass, a reasonable cost, and in a timeframe of about 10-15 years.
