Celestis’ Sunjammer solar sail is a NASA-funded starship that will travel many millions of miles toward the Sun, demonstrating – for the first time – a solar sail’s ability to fly and to navigate, as well as to provide early warning against the dangers of solar storms heading Earth’s way. This will also be a memorial spaceflight mission, carrying the cremated remains of people on this history-making journey.
But what are these solar storms, and what dangers do they pose?

The solar storms are technically called “coronal mass ejections” (CMEs):
Satellites that currently observe the Sun for CMEs. The STEREO spacecraft travel in the same orbit around the Sun as Earth's orbit. Sunjammer will fly to the same position as the SOHO and ACE spacecraft -- to a point called "L1," where the gravitational effects of the Sun and Earth offset each other. If Sunjammer succeeds, future solar sails could maintain observing locations even closer to the Sun, and thus provide earlier warning of CMEs than existing satellites. Image Credit: NASA[/caption]
The Celestis Sunjammer mission will be truly historic, helping to defend Earth from dangerous CMEs. Reservations for this important mission are open. Pre-arrangements can also be made for yourself. Contact Celestis today for more information.

- The outer layer of the Sun is referred to as the Sun’s “corona.”
- From time to time, the corona will erupt, spewing (ejecting) huge amounts of charged particles (part of the mass of the Sun) into space.
- The danger is, if one of these CME’s impacts Earth, the charged particles -- interacting with Earth’s magnetic field -- can play havoc with electricity grids, radio communications, computer systems, etc., which could result in widespread chaos lasting for years at a time.

When Star Trek's Nichelle Nichols died in late July at age 89, she was lauded as the trailblazer she was during her lifetime. However, her story is far from over. In early 2023, she will fly alongside the DNA of her son, Kyle Johnson, aboard Celestis’ Enterprise Flight. In addition, the Nichelle Nichols Foundation – announced today, on what would have been her 90th birthday – will continue to promote diversity in STEM fields.
