The European Space Agency (ESA) is running some of the final tests required to launch its Hera mission this October, which aims to investigate the asteroid that NASA intentionally slammed a spacecraft into back in 2022. The goal is to gather more accurate information about the collision to help develop systems that can protect our planet by deflecting asteroids that head our way.

The spacecraft for the Hera mission is undergoing preflight testing, alongside the Guidance Navigation and Control (GNC) system it needs to maneuver around the Dimorphos and Didymos binary asteroid system. The GNC system is being validated via virtual tests conducted in Spain and Germany using replicas of Hera spacecraft components.

“The system for Hera’s interplanetary cruise phase — which of course is the most critical to be ready for launch — is now fully tested using the actual spacecraft flight model,” said ESA GNC engineer Jesus Gil Fernandez in the announcement blog. “This phase will end at asteroid arrival when camera images will be used to distinguish the asteroid from background stars by spotting its gradual motion across successive images.”

The main objective of the autonomous Hera mission is to assess what actually happened to Dimorphos, the smaller asteroid that NASA’s Double Asteroid Redirection Test (DART) mission impacted, to help guide planetary defense systems. Even for a space mission, the nature of the paired asteroid system — which has a combined gravity field tens of thousands of times weaker than Earth — makes it a difficult destination to navigate. The collision with NASA’s DART spacecraft has also shifted the orbit around Didymos and likely made some major changes to its overall shape.

The ESA is currently focused on the GNC for the follow-on proximity operations phase of Hera’s mission, according to Gil Fernandez, which is needed to bring the spacecraft as close as one kilometer (0.6 miles) to the two asteroids.

Like the technology behind autonomous cars, Hera’s GNC system will use a variety of different data sources to operate safely around Didymos. “Its main data source will be its main Asteroid Framing Camera, whose images are being used both for science and navigation,” said Gil Fernandez. “These images will be combined with other inputs to make a robust estimate of its position.”

You can read all the specific technical details about how the ESA is planning for Hera to overcome these navigational issues, including surface feature tracking and repeat velocity changes, in the agency’s blog post

Provided the Hera mission is launched successfully this October, the spacecraft is expected to spend two years journeying through space — making a flyby past Mars to gain speed and observe its moon Deimos — before reaching the Didymos binary asteroid system in October 2026.

Starlink Mini brings space internet to backpackers

Published

SpaceX’s Starlink internet-from-space service is already available for boatsplanes, vanlifersAmazonian villages, and rural homes in over 75 countries — now it’s coming to backpackers.

The new compact DC-powered Starlink Mini is about the size of a thick laptop and integrates the Wi-Fi router right inside the dish. And despite using less power than other Starlink terminals, it can still deliver speeds over 100Mbps.

“This product will change the world,” claimed SpaceX CEO Elon Musk on X, saying it took less than five minutes to setup.

Notably, the Mini kit consumes an average of just 20-40W compared to the 33-62W we measured just two years ago with a Standard Actuated dish and separate AC-powered Wi-Fi router. That means you can power the Mini dish for two to three hours from something like an Anker Prime 27,650mAh (99.54Wh) power bank, or a little over an hour with smaller 10,000mAh (40Wh) portable batteries you probably already have laying about. It requires a USB-C PD power source with a minimum rating of 100W (20V/5A). 

The Mini dish measures 11.75 x 10.2 x 1.45 inches (298.5 x 259 x 38.5mm) and weighs just 2.43 pounds (1.1kg), or 3.37 pounds (1.53kg) with the 49.2 foot (15m) DC power cable and kickstand. It has an IP67 rating meaning it’s protected from dust and rain, including short periods of water immersion.

In the US, Starlink Mini is an add-on to Residential plans — at least for now. The Mini kit costs $599 which is $100 more than the standard dish, and will cost an extra $30 per month to add the Mini Roam service to existing $120 Residential plans. That gives Starlink Mini users up to 50GB of mobile data each month, with the option to purchase more for $1 per GB, according to early-access invitations sent to some exiting US Starlink customers. 

While Starlink Mini is new to the US, a Starlink support page says it’s already available in Colombia, El Salvador, Guatemala, and Panama where it can be purchased with Mini Service or Mobile – Regional Service plans. In those countries, there’s no data or speed caps to use Mini, and in-motion and ocean use is not allowed. SpaceX says it’ll expand to more markets over time.

“Our goal is to reduce the price of Starlink, especially for those around the world where connectivity has been unaffordable or completely unavailable,” reads the Starlink support page. “In regions with high usage, like the US, where Starlink Mini places additional demand on the satellite network, we are offering a limited number of the Starlink Mini Kits to start at a higher price point.”

As a standalone service, Starlink Mini could be transformative for anyone in need of an inexpensive and sharable internet service that efficiently sips DC battery power. This includes families that depend upon a cobbled together solar generator for power, a squad of soldiers trying to fight back an invasion, or just bikepackers and overlanders taking the road less traveled.

Elon Musk has another secret child with exec at his brain implant company

Elon Musk, who has long touted claims about the world’s supposed depopulation crisis, had another child with an executive at his brain implant company Neuralink, according to a report from Bloomberg. Neuralink director Shivon Zilis reportedly had the child with Musk earlier this year.

As noted by Bloomberg, Musk has repeated that line several times in the past, including during a 2022 interview with Tucker Carlson and again during an interview at the Milken Institute conference in May. He told Carlson “a collapsing birth rate is the biggest danger civilization faces, by far.” In 2021, Musk’s nonprofit organization donated $10 million to the University of Austin to fund the Population Wellbeing Initiative, a research group that studies the human population.

The revelation also follows multiple reports alleging inappropriate conduct from Musk in the workplace and with subordinates. A recent report from The Wall Street Journal said Musk had a sexual relationship with a former SpaceX intern who later became one of the company’s executives. Another employee says she refused Musk’s requests to have children with him several times, according to the Journal.

Youth plaintiffs in Hawaii reach historic climate deal

Published

A group of young plaintiffs reached a historic climate settlement with the state of Hawaii and Hawaii Department of Transportation in a deal that will push the state to clean up tailpipe pollution.

The 13 youth plaintiffs filed suit in 2022 when they were all between the ages of 9 and 18. In the suit, Navahine F. v. Hawaii Department of Transportation (HDOT), they alleged that the state and HDOT had violated their right to “a clean and healthful environment,” which is enshrined in Hawaii’s constitution.

“We got what we came for, and we got it faster than we expected.”

The settlement, reached on Thursday, affirms that right and commits the DOT to creating a plan to reach zero greenhouse gas emissions from transportation by 2045. To hit that goal, the state will have to dedicate at least $40 million to building out its EV charging network by the end of the decade and complete new pedestrian, bicycle, and transit networks over the next five years. The settlement also creates a new unit within HDOT tasked with coordinating CO2 emission reductions and a volunteer youth council to advise HDOT.

“I am so proud of all the hard work to get us to this historic moment. We got what we came for, and we got it faster than we expected,” the lead plaintiff, Navahine F., said in an emailed statement.

Back in 2018, Hawaii committed to reaching net-zero carbon dioxide emissions by 2045 — in line with what climate research determined was necessary to meet the Paris climate accord goal of stopping global warming. But the state wasn’t doing enough to reach that goal, the plaintiffs alleged. Transportation makes up the biggest chunk of the state’s greenhouse gas pollution.

“Climate change is indisputable,” Ed Sniffen, HDOT director of transportation, said in a press release. “Burying our heads in the sand and making it the next generation’s problem is not pono.”

Youth in Montana scored another historic legal win last year after the first climate case of its kind to go to trial. A state court found that a Montana policy that barred officials from considering the consequences of climate change when permitting new energy projects violated the rights of the plaintiffs to a “clean and healthful environment.” The lawsuit in Hawaii was expected to be the next landmark youth climate case to go to trial in the US. Several other state and federal youth climate suits are still pending in the US.
