Get Ready For More Interstellar Objects

Gregory Laughlin and Malena Rice weren't exactly surprised a few weeks ago when they learned that a second interstellar object had made its way into our solar system.

This paper discusses the physics, engineering and mission architecture relating to a gram-sized interstellar probe propelled by a laser beam.

In April last year, billionaire Yuri Milner announced the Breakthrough Starshot Initiative. He plans to invest 100 million US dollars in the development of an ultra-light light sail that can be accelerated to 20 percent of the speed of light to reach the Alpha Centauri star system within 20 years.

The Breakthrough Starshot initiative aims to launch a gram-scale spacecraft to a speed of v∼0.2c, capable of reaching the nearest star system, α Centauri, in about 20 years.

Last month The Breakthrough Foundation announced its plans for humanity's first interstellar mission, Project Starshot. While much has ben written about that announcement, only the basic details behind the technology have been released. Until now.

Alpha Centauri As Seen From Saturn

The nearest star system (and the destination of Breakthrough Starshot) the trinary star Alpha Centauri, hangs above the horizon of Saturn.

Plans for Earth's first starships are being announced today in New York City. At a midday press conference, Yuri Milner's Breakthrough Prize Foundation is unveiling its latest project: "Breakthrough Starshot".

Shred a document, and you can piece it back together. Burn a book, and you could theoretically do the same. But send information into a black hole, and it's lost forever.

The team responsible for the Oscar-nominated visual effects at the center of Christopher Nolan's epic, Interstellar, have turned science fiction into science fact by providing new insights into the powerful effects of black holes.

Based on the latest evidence and theories our galaxy could be a huge wormhole (or space-time tunnel; have you seen "Interstellar?") and, if that were true, it would be "stable and navigable."

Visiting Interstellar's Spacecraft

I had an opportunity to stand next to a spaceship from the film "Interstellar" last Friday and fly through a simulation of yet another spacecraft from the film.

The new Paramount film "Interstellar" imagines a future where astronauts must find a new planet suitable for human life after climate change destroys the Earth's ability to sustain us.

Voyager 1 Has Left Our Solar System

Thirty-five years after its launch, Voyager 1 appears to have travelled beyond the influence of the Sun and exited the heliosphere, according to a new study appearing online today.

NASA's Voyager 1 spacecraft has entered a new region at the far reaches of our solar system that scientists feel is the final area the spacecraft has to cross before reaching interstellar space.

Thirty-five years ago yesterday, NASA's Voyager 2 spacecraft, the first Voyager spacecraft to launch, departed on a journey that would make it the only spacecraft to visit Uranus and Neptune and the longest-operating NASA spacecraft ever.

Data from NASA's Voyager 1 spacecraft indicate that the venerable deep-space explorer has encountered a region in space where the intensity of charged particles from beyond our solar system has markedly increased. Voyager scientists looking at this rapid rise draw closer to an inevitable but historic conclusion - that humanity's first emissary to interstellar space is on the edge of our solar system.

Using Pulsars To Navigate in Space

Autonomous Spacecraft Navigation Based on Pulsar Timing Information

"Pulsars are rapidly rotating neutron stars that are observable as variable celestial sources of electromagnetic radiation. Their periodic signals have timing stabilities comparable to atomic clocks and provide characteristic temporal signatures that can be used as natural navigation beacons, quite similar to the use of GPS satellites for navigation on Earth."

Keith's note: This is the plaque placed on the Voyager 1 and 2 probes, now heading out of our solar system into interstellar space. According to Wikipedia: "The drawing in the lower left-hand corner of the cover is the pulsar map previously sent as part of the plaques on Pioneers 10 and 11. It shows the location of the solar system with respect to 14 pulsars, whose precise periods are given."
