NASA has called the descent the most difficult part of the mission and they coined the landing as 'Seven minutes of terror'. Stay tuned for more updates for Perseverance landing. The Debate. Breaking News. They equipped it with the Nvidia board, antennas, filters, and the S-band radios. At the Army's behest, the team came up with a plan to use the flying network to demonstrate leader-follower autonomous-vehicle mobility. It's a convoy : A human drives a lead vehicle, and up to eight autonomous vehicles follow behind, using routing information transmitted to them from the lead vehicle.
Just as in the tip-and-cue demonstration, the team established a heterogeneous 5G and S-band network with the upgraded 5G payload and a series of supporting copters that formed a connected S-band mesh network. This mesh connected the convoy to a second, identical convoy several kilometers away, which was also served by a copter-based 5G and S-band base station.
After the commander initiated the mission, the Freefly Alta X flew itself above the lead vehicle at a height of about meters and connected to it via the 5G link. The HiveStar mission-controller software directed the supporting multicopters to launch, form, and maintain the mesh network. The vehicle convoy started its circuit around a test range about 10 km in circumference.
During this time, the copter connected via 5G to the lead convoy vehicle would relay position and other telemetric information to the other vehicles in the convoy, while following overhead as the convoy traveled at around 50 km per hour. Data from the lead vehicle was shared by this relay to following vehicles as well as the second convoy via the distributed multicopter-based S-band mesh network. Current 5G standards do not include connections via satellites or aircraft.
But planned revisions, designated Release 17 by the 3rd Generation Partnership Project consortium, are expected next year and will support nonterrestrial networking capabilities for 5G. Chris Philpot. The team also challenged the system by simulating the loss of one of the data links either 5G or S-band due to jamming or malfunction.
If a 5G link was severed, the system immediately switched to the S band, and vice versa, to maintain connectivity. Such a capability would be important in a war zone, where jamming is a constant threat. Though encouraging, the Hydra and HiveStar trials were but first steps, and many high hurdles will have to be cleared before the scenario that opens this article can become reality.
Chief among these is expanding the coverage and range of the 5G-enabled networks to continental or intercontinental range, increasing their security, and managing their myriad connections. We are looking to the commercial sector to bring big ideas to these challenges.
Satellite constellations, for instance, can provide a degree of global coverage, along with cloud-computing services via the internet and the opportunity for mesh networking and distributed computing. And though today's 5G standards do not include space-based 5G access, the Release 17 standards coming in from the 3rd Generation Partnership Project consortium will natively support nonterrestrial networking capabilities for the 5G ecosystem. So we're working with our commercial partners to integrate their 3GPP-compliant capabilities to enable direct-to-device 5G connectivity from space.
Security will entail many challenges. Cyberattackers can be counted on to attempt to exploit any vulnerabilities in the software-defined networking and network-virtualization capabilities of the 5G architecture. The huge number of vendors and their suppliers will make it hard to perform due diligence on all of them.
And yet we must protect against such attacks in a way that works with any vendor's products rather than rely, as in the past, on a limited pool of preapproved solutions with proprietary and incompatible security modifications. The advent of ultrafast 5G technology is an inflection point in military technology.
Another interesting little challenge is presented by the 5G waveform itself. It's made to be easily discovered to establish the strongest connection. But that won't work in military operations where lives depend on stealth. Modifications to the standard 5G waveform, and how it's processed within the gNodeB, can achieve transmission that's hard for adversaries to pick up.
Perhaps the greatest challenge, though, is how to orchestrate a global network built on mixed commercial and military infrastructure. To succeed here will require collaboration with commercial mobile-network operators to develop better ways to authenticate user connections, control network capacity, and share RF spectrum.
For software applications to make use of 5G's low latency, we'll also have to find new, innovative ways of managing distributed cloud-computing resources. It's not a leap to see the advent of ultrafast 5G technology as an inflection point in military technology. As artificial intelligence, unpiloted systems, directed-energy weapons, and other technologies become cheaper and more widely available, threats will proliferate in both number and diversity.
Communications and command and control will only become more important relative to more traditional factors such as the physical capabilities of platforms and kinetic weapons.
This sentiment was highlighted in the summary of the U. National Defense Strategy , the strategic guidance document issued every four years by the U.
DOD: "Success no longer goes to the country that develops a new technology first, but rather to the one that better integrates it and adapts its way of fighting. Here, it is worth noting that Chinese companies are among the most active in developing 5G and emerging 6G technologies. Chinese market share could very well increase: According to the Council on Foreign Relations , the Chinese government backs companies that build 5G infrastructures in countries China invests in as part of its Belt and Road Initiative.
Norway, notably, is exploring dedicating software-defined networks in commercial 5G infrastructure to support military missions. Perhaps this convergence of commercial and defense-sector development around 5G, 6G, and future communications technologies will lead to powerful and unexpected commercial applications. The defense sector gave the world the Internet. The world now gives militaries 5G communications and beyond.
Let's find out what the defense sector can give back. Authors' note: 5G. The authors wish to acknowledge the help of Brandon Martin in the writing of this article. Explore by topic.

As part of the programme known as Mars Sample Return, a separate mission will be sent to land on Mars to pick up the tubes using a "fetch" rover.
The ascent vehicle blasts the samples into Martian orbit where they are captured by an orbiter. This orbiter will then deliver the sample containers to Earth, possibly by Follow Paul on Twitter.
