Jupiter’s moons create invisible ‘killer’ waves that could destroy spacecraft

Posted by in categories: particle physics, robotics/AI, space travel

Here on Earth, electromagnetic waves around the planet are typically pretty calm. When the Sun fires a burst of charged particles at the Earth we are treated to an aurora (often called Northern Lights), but rarely are they a cause for concern. If you were to head to Jupiter, however, things would change dramatically.

In a new study published in Nature Communications, researchers describe the incredible electromagnetic field structure around two of Jupiter’s moons: Europa and Ganymede. The invisible magnetic fields around these bodies is being powered by Jupiter’s own magnetic field, and the result is an ultra-powerful particle accelerator of sorts, which might be capable of seriously damaging or even destroying a spacecraft.

“Chorus waves” are low-frequency electromagnetic waves that occur naturally around planets, including Earth. Near our planet they’re mostly harmless, but they do have the capability to produce extremely fast-moving “killer” particles that could cause damage to manmade technology if we happened to be in the wrong place at the wrong time.

SpaceX organizes inaugural conference to plan landings on Mars

Posted by in categories: Elon Musk, government, space travel

No one can deny that SpaceX founder Elon Musk has thought a lot about how to transport humans safely to Mars with his Big Falcon Rocket. But when it comes to Musk’s highly ambitious plans to settle Mars in the coming decades, some critics say Musk hasn’t paid enough attention to what people will do once they get there.

However, SpaceX may be getting more serious about preparing for human landings on Mars, both in terms of how to keep people alive as well as to provide them with something meaningful to do. According to private invitations seen by Ars, the company will host a “Mars Workshop” on Tuesday and Wednesday this week at the University of Colorado Boulder. Although the company would not comment directly, a SpaceX official confirmed the event and said the company regularly meets with a variety of experts concerning its missions to Mars.

This appears to be the first meeting of such magnitude, however, with nearly 60 key scientists and engineers from industry, academia, and government attending the workshop, including a handful of leaders from NASA’s Mars exploration program. The invitation for the inaugural Mars meeting encourages participants to contribute to “active discussions regarding what will be needed to make such missions happen.” Attendees are being asked to not publicize the workshop or their attendance.

Sorry Elon Musk, But It’s Now Clear That Colonizing Mars Is Unlikely — And A Bad Idea

Posted by in categories: Elon Musk, engineering, environmental, government, space travel, sustainability

This article was originally published at The Conversation. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights.

Space X and Tesla founder Elon Musk has a vision for colonising Mars, based on a big rocket, nuclear explosions and an infrastructure to transport millions of people there. This was seen as highly ambitious but technically challenging in several ways. Planetary protection rules and the difficulties of terraforming (making the planet hospitable by, for example, warming it up) and dealing with the harsh radiation were quoted as severe obstacles.

Undeterred, Musk took a first step towards his aim in February this year with the launch of a Tesla roadster car into an orbit travelling beyond Mars on the first Falcon Heavy rocket. This dramatically illustrated the increasing launch capability for future missions made available by partnerships between commercial and government agencies.

Scientists Discover a Giant Rogue Planet Bumbling Around Space

Posted by in category: space travel

What a dumb planet.


Not all who wander are lost, but that might be the case for a newly discovered rogue planet. Scientists have found evidence of a giant planetary mass outside our solar system that appears to be traveling without any sort of set orbit or parent star.

This bumbling fool of a planet was first discovered by astronomers using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA). From the radio astronomy observatory, scientists were able to pick up its magnetic activity and study it, the findings of which were made public on Thursday. It’s the first time the observatory’s radio-telescope detection was able to pick up a planetary-mass object beyond our solar system.

Astronomers Finally Understand 170-Year-Old Stellar Eruption

Posted by in categories: materials, space travel

Data collected from the Gemini South telescope in Chile has shed light on a nearly-200-year-old stellar eruption.

Gemini spectroscopy shows that ejected material from the blast was the fastest ever seen from a star that remained intact.

Britain looks to bring commercial rocket launches to home soil

Posted by in categories: government, habitats, space travel

The British government is preparing to launch its first commercial rocket from the country by 2021, and has upped its funding and partnerships with American companies to do so, reports CNBC.

The details: Lockheed Martin has already been allotted the largest chunk of UKSA’s (United Kingdom Space Agency) funding, receiving over $30 million “to develop an orbital launch site for small rockets in Melness, Scotland.” The company told CNBC, “[t]he launcher will be a flight-proven, dedicated small sat vehicle.” Richard Branson’s Virgin Orbit also locked in a deal with UKSA “to launch its LauncherOne rocket from Cosmic Girl,” and plans to be the first to launch a commercial rocket from the island in the next three years.

Work begins on rocket engines for SLS flights a decade from now

Posted by in category: space travel

Long lead time

This timeline represents quite a long lead-up for the engines and the fifth flight. Nominally, NASA now plans to make the first SLS launch in June 2020, although that date may slip into 2021 or later if further technical or hardware problems arise with the new rocket. Eventually, NASA wants to get to a cadence of one flight every year of the rocket, but that is unlikely to happen right away. Therefore, the fifth flight of the SLS rocket is unlikely before the second half of the 2020s.

There is also some question as to whether the rocket will actually make multiple flights. By the mid-2020s, Blue Origin’s large New Glenn booster should be flying. Additionally, SpaceX’s larger Big Falcon Rocket may also have begun making test flights by then. Both of these boosters would offer NASA significant lift with privately developed, reusable rockets at a fraction of the cost of the SLS rocket.
