I4IS presents at the Scottish Dark Sky Observatory

23 August 2015

Milky Way galaxy over Pakistan

Rob Swinney and Terry Regan attended a special event at the Scottish Dark Sky Observatory in August. Over two evenings the pair, representing both i4is and the British Interplanetary Society discussed the prospects of real interstellar flight in the near future.

The interstellar minimum

13 August 2015

As a part of our educational initiatives, our team has recently put together a small test paper for starship design, known as ‘the interstellar minimum’ after the famous Russian physicist Lev Landau and his ‘theoretical minimum’ entrance exam for university degree programs.

Issue 10 of Principium, the quarterly publication of the Initiative and Institute for Interstellar Studies is now published.

Pluto flyby success

15 July 2015

Pluto

Yesterday the NASA New Horizons spacecraft successfully executed a flyby of the dwarf planet Pluto, one of the Trans-Neptunian objects, to within a distance of just over 12,500 km.

Principium 9

Project Dragonfly: Kickstarter campaign launched

18 April 2015

Sail

Project Dragonfly is a feasibility study for an interstellar mission, conducted by small, distributed spacecraft, propelled primarily by laser sails. The spacecraft shall be capable of reaching the target star system within a century and be able to decelerate.

The Mariner program

26 February 2015

The Mariner program was a joint NASA/JPL initiative which ran from 1962 to 1973 and saw robotic probes sent to nearly all of the planets of the solar system. The program achieved many firsts, including the first planetary flyby, the first pictures from another planet, the first planetary orbiter, the first gravity assist manoeuvre.

To the Voyagers and escaping from the sun

25 February 2015

Uranus Voyager 2

The Voyager 1 and 2 spacecraft were launched in the 1970s. They are now heading out into interstellar space. One day, we may build faster spacecraft and overtake them.

Mission to 2002 XV93

21 May 2026

Adam Hibberd Tony Dunn’s fantastic animation of a trajectory discovered by my software ‘Optimum Interplanetary Trajectory Software’ (OITS) to the distant Kuiper Belt Object (KBO) designated 2002 XV93. This object has recently made news in that it has a tenuous atmosphere, probably caused by an impact quite recently. Scientists believe this atmosphere will last no […]

Mission to an Interstellar Object

5 May 2026

Adam Hibberd Many readers in-the-know will have heard of the future ESA ‘Comet Interceptor’ mission, due to launch in 2029. For those not-in-the-know it is a spacecraft desgined to loiter at the famous Sun/Earth Lagrange 2 (L2) point for a few years, waiting for a ‘pristine’ Oort Cloud comet to come flying in to the […]
