A sampling of the stories is available.

Going InterstellarCo-editor Les Johnson is a NASA physicist and author.  Check out the list of his books at Baen.

And the other co-editor Jack McDevitt is the Nebula Award–winning author of The Academy [Amazon link] series, including The Long Sunset [Amazon link]. McDevitt posted about the new release of the book in paperback:  Blog #80

As co-editor, I am of course not objective about the collection. Nevertheless I can’t avoid mentioning that the fiction is compelling. What might it really be like to board an interstellar vehicle on a mission to a nearby star that will take years or decades? That some of us would realize, going out, that we would not live long enough to return? And what would it feel like to actually visit another star?

NIAC project aims to image exoplanets with solar gravity lens system enabled by advanced solar sail

Xplore sent me this press release:

NASA $2M Grant Advances Study to Directly Image Exoplanets Light Years Away
Xplore’s Advanced Solar Sail Design will be the Fastest Spacecraft Ever Made,
Expanding Xplore’s Reach Beyond the Inner Solar System

Xplore Inc., a commercial space exploration company providing Space as a Service™ today announced they and their teammates won a NASA Innovative Advanced Concepts (NIAC) Phase III award for a two-year, $2M NASA grant to further mature the Solar Gravity Lens Focus (SGLF) architecture to image planets in orbit around distant stars starting with a Technology Demonstration Mission (TDM). Dr. Slava G. Turyshev, a NIAC Fellow and Senior Research Scientist at NASA’s Jet Propulsion Laboratory (JPL) is the Principal Investigator leading the SGLF mission which includes Xplore, JPL and The Aerospace Corporation. The SGLF mission study is only the third Phase III award granted in the NIAC program ever.

Reaching the focus region where the Sun’s gravity acts like a magnifying lens to the background sky is an immense technological challenge. This region, the SGLF, is over 500 times the distance between Earth and the Sun (547 AU). One Astonomical Unit (AU) is the distance from Earth to the Sun, about 93 million miles (149.5 million km). Even by using our fastest deep space probe, Voyager 1, moving at 11 miles/s (17 km/s) it will take over 150 years to reach just the edge of the SGLF region.

During the previous two NIAC phases nearly every credible propulsion technology was assessed to not only accurately navigate across this vast distance, but also to communicate and operate once at the SGLF — all within a goal of 25 years from launch. To reach the SGLF on a timescale of 25 years requires a propulsion system capable of accelerating a spacecraft to a speed seven times faster than Voyager 1 (> 20 AU/yr or 100 km/s). The resulting propulsion technology was found to meet both the high speed requirement and the proposed architecture of sending many vehicles to the SGLF. This propulsion does not exploit chemical or nuclear reactions, but simply harnesses sunlight reflecting from a solar sail.

As a key enabler for the SGLF mission, Xplore will design the spacecraft for the SGLF’s Technology Demonstration Mission (TDM). The TDM vehicle as pictured is an advanced solar sail design based upon L’Garde’s SunVane concept. The SunVane concept addresses the control, packaging and scalability challenges of traditional large planar solar sails by breaking up the required overall sail area into smaller rotatable vanes distributed across a lightweight truss. Xplore will transition this concept to a prototype design as a first step toward demonstrating the key technologies necessary to achieve the SGLF mission. The goal for the Xplore TDM vehicle using current technologies is to reach speeds in excess of two to three times that of Voyager 1 (5-8 AU/year). At these unprecedented speeds it would allow the TDM vehicle to reach Jupiter in less than a year and Saturn in two years.

Xplore Founder Lisa Rich said,

“Xplore is laying the groundwork to revolutionize the transit speed to destinations in our solar system, and beyond. Once Xplore completes the design, build and first flight of the TDM vehicle, the company would accelerate these missions — perhaps sending one per year, to rapidly advance solar system exploration while providing fast reaction options for flybys of newly-discovered interstellar objects like Oumuamua and high energy intercepts for planetary defense.”

The TDM will enable rapid transit to dramatically transform and ease the exploration of the outer solar system and Kuiper belt objects. At 5-8 AU per year, the TDM vehicle’s extraordinary speed will allow it to reach Voyager in 20 years. To put these distances into perspective, New Horizons launched in 2006 and thirteen years later performed the first flyby of Ultima Thule, a distant Kuiper Belt object that lies 1 billion miles (1.6 billion km) beyond Pluto.

Alan Stern, planetary scientist, Associate Vice President of the Southwest Research Institute and the Principal Investigator on New Horizons mission to Pluto said,

“This is an incredible mission with incredible technology. I am incredibly excited to see it selected for study by NIAC. SGLF offers to revolutionize both exoplanet science and propulsion technology if implemented.”

The design of the TDM spacecraft is led by Xplore Founder and Chief Technology Officer, Dr. Darren Garber, who helped develop L’Garde’s SunVane concept and provided operational support to LightSail. Dr. Garber will coordinate with JPL and Aerospace team members to ensure that the TDM vehicle’s design and future flight will represent the next step toward traversing 500 AU in 25 years or less.

Dr. Louis D. Friedman, Xplore Advisor and Co-Founder of The Planetary Society, worked on numerous flagship missions including Mariner, Voyager, Magellan and the Mars Program. A well-known champion of the Halley’s Comet Rendezvous-Solar Sail project back in the 70s with Dr. Carl Sagan, Dr. Friedman said,

“I’m proud that Xplore, led by our colleague Dr. Slava Turyshev, will advance the vision for space exploration Carl Sagan and I put in motion many years ago. The ability to harness the power of the Sun to rapidly transit to distant corners of our universe is a groundbreaking effort that will impact the science community for generations.”

Xplore’s team is comprised entirely of experienced U.S. space professionals who have supported all aspects of the design, development and operations of advanced technology missions for commercial, civil and national security space customers.

For the TDM, Dr. Garber and Xplore’s advanced engineering team will leverage key components, software and system engineering processes employed for its Xcraft™, a high-performance, ESPA-class, multi-mission spacecraft uniquely designed for missions in the inner solar system with a planned lunar radar mapping mission in early 2022. Their expertise will further define the SGLF Phase III study mission and architecture analysis such as using clusters of follow-on TDM vehicles to collectively mitigate risk and lower total system cost. Multiple mass-produced TDM spacecraft offer resiliency and scalability for a future decades-long mission, and the concept could allow other partners to contribute their own set of clustered spacecraft to cooperatively operate during the journey to the solar gravitational lens region in deep space.

Lisa Rich said,

“Designing the fastest object ever made in the history of humanity is a challenge worthy of the legacy of Carl Sagan, and we look forward to advancing solar sail technologies with our Advisor, Dr. Lou Friedman. SGLF aligns with Xplore’s long-term vision for frequent, low-cost commercial missions to deep space. The ability to rapidly travel anywhere in the solar system expands our human footprint and will open up new avenues for scientific exploration.”

Space Adventures to fly private citizens on SpaceX Crew Dragon

Space Adventures and SpaceX announced today plans to fly four private citizens on a Crew Dragon flight. The Dragon would not go to the ISS but would be a “free flyer” mission in which the citizen astronauts would enjoy microgravity and views of Earth in the spacecraft. The spacecraft would go to 2-3 times the altitude of the ISS. The first launch is aimed for the late 2021 to mid-2022 time frame. The mission would last up to five days.

Space Adventures Announces Agreement with SpaceX
to Launch Private Citizens on the Crew Dragon Spacecraft

Mission profile provides opportunity to break a world record

February 18, 2020 – Vienna, Va. — Building on the success of Crew Dragon’s first demonstration mission to the International Space Station in March 2019 and the recent successful test of the spacecraft’s launch escape system, Space Adventures, Inc. has entered into an agreement with SpaceX to fly private citizens on the first Crew Dragon free-flyer mission. This will provide up to four individuals with the opportunity to break the world altitude record for private citizen spaceflight and see planet Earth the way no one has since the Gemini program.

If interested parties are secured, this mission will be the first orbital space tourism experience provided entirely with American technology. Private citizens will fly aboard SpaceX’s fully autonomous Crew Dragon spacecraft launched by the company’s Falcon 9 rocket, the same spacecraft and launch vehicle that SpaceX will use to transport NASA astronauts to the International Space Station.

“This historic mission will forge a path to making spaceflight possible for all people who dream of it, and we are pleased to work with the  Space Adventures’ team on the mission,”

said Gwynne Shotwell, President and Chief Operating Officer, SpaceX.

“Creating unique and previously impossible opportunities for private citizens to experience space is why Space Adventures exists. From 2001-2009 our clients made history by flying over 36 million miles in space on eight separate missions to the ISS. Since its maiden mission in 2010, no engineering achievement has consistently impressed the industry more than the Dragon/Falcon 9 reusable system. Honoring our combined histories, this Dragon mission will be a special experience and a once in a lifetime opportunity – capable of reaching twice the altitude of any prior civilian astronaut mission or space station visitor,”

said Eric Anderson, Chairman, Space Adventures.

Our Dream Of Spaceflight

“Frozen Orbit” – A new space novel by Patrick Chiles

Patrick Chiles has released the new novel, Frozen Orbit:

The Beginning of Life Awaits at the End of the Solar System

Frozen Orbit by Patrick Chiles

When a tiny space probe hurtled past Pluto in 2015, no one could know that its most amazing discovery would remain hidden for years. Only when a long-lost Soyuz is destroyed in the skies above Siberia does the truth begin to emerge.

About to embark on NASA’s first expedition to the outer planets, the crew of the spacecraft Magellan learns someone else has beaten them by a few decades: a top-secret Soviet project codenamed Arkangel. It was a mission that began before most of them were even born, and the Kremlin believes it drove their most trusted crew mad.

During their long race to the Kuiper Belt, astronauts Jack Templeton and Traci Keene unwind a decades-old mystery buried in the pages of a dead cosmonaut’s journal. Challenging their own beliefs about the nature of humanity, they will soon confront the question of existence itself.

Check out also Patrick’s other novels, Farside and Perigee.
